EXECUTIVE SUMMARY-PERIOD 1

In the Division of Waste Management (DWM) Job Code (JC), the Center for Nuclear Waste Regulatory Analyses (CNWRA) staff transmitted External Peer Review of the Total-system Performance Assessment Version 3.2 Code-Letter Report and Draft Environmental Impact Statement Evaluative Review Comments. The staff produced papers and posters for presentation at various technical meetings. These papers have been or will be submitted for acceptance in recognized technical journals. Staff also participated in workshops, symposia, and other technical meetings.

The DWM JC year-to-date (YTD) cost variance was - 11.3 percent. Spending fell slightly from the last period, but again exceeded spending estimates for the period.

In the TankWaste Remediation System JC, staff pursued activities in the various subtasks, and they attended several design review meetings. The YTD cost variance was 24.2 percent. Spending declined from the previous period, but the cumulative variance is expected to decrease as new activities begin.

In the Dry Transfer System (DTS) JC, staff continued developing the DTS draft safety evaluation report (SER), using CNWRA and Southwest Research Institute (SwRI) staffs and one consultant. The YTD cost variance was 7.9 percent, down sharply from the first period as a result of intensive work on the SER. Spending increased significantly since the last period, and is expected to remain fairly steady as the staff prepares the draft SER.

In the Centralized Interim Storage Facility (CISF) JC, staff pursued the review of the U.S. Department of Energy response to the Spent Fuel Project Office request for additional information on the HI-STAR and HI-STORM topical report for high seismic risk sites. The YTD cost variance for the CISF was 43.1 percent. Spending remained constant from last period, but it may increase significantly after the NRC comments on the draft assessment report are received at the CNWRA.

In the Private Fuel Storage Facility (PFSF) JC, staff, in addition to visiting the site at Utah, participated in the Nuclear Regulatory Commission (NRC) and PFSF meeting at Salt Lake City, Utah, on revised seismic design and worked interactively with the NRC staff to prepare the public release version of the site-specific portion of the PFSF SER. The YTD cost variance was 26.6 percent. Spending rose significantly from last period, and it is expected to be generally consistent with estimated spending for the following period.

1.3 Igneous Activity (IA)

Staff attended and made presentations at the USGS workshop on probabilistic risk assessment for geologic hazards. The goals of this workshop were to (i) bring together experts in probabilistic hazard and risk assessment methodologies for earthquakes, floods, landslides, and volcanoes; (ii) increase awareness of the tools used to assess hazard and risk across disciplines; and (iii) determine if a common framework for assessing risks from different geologic hazards can be developed. Staff attended primarily to assess how the volcanic hazard models developed at the CNWRA for the proposed HLW repository at YM compare with hazard models developed in other disciplines by the USGS and others.

Work continued this period on the analysis of geophysical data collected at the Cerro Negro volcano, Nicaragua, during field work conducted shortly after the August eruption of this small-volume basaltic cinder cone. Staff visited the Rosensteil School of Marine and Atmospheric Sciences to learn techniques for numerical modeling of 3D deformation, which was observed during basaltic dike injection during the 1999 Cerro Negro eruption. Preliminary modeling of the Cerro Negro fracture system indicates that surface deformation occurred with dike injection to a depth of <100 m. Modeling of Cerro Negro transient electromagnetic data is continuing at the University of Southern Maine.

Physical analog experiments for magma-repository interactions continued this period. These experiments are conducted to evaluate the rate and extent of flow if basaltic magma enters a repository drift. These experiments aim to evaluate the current DOE TSPA assumption of limited flow into a drift. Several low volatile (golden syrup) and volatile-rich (gum-resin-acetone) experiments were conducted successfully during this period. Work focused on development of an equation of state for the gum-resin-acetone mixture to better quantify the analogy with basaltic magma.

Staff gave two invited lectures at Idaho State University this period. These lectures presented risk assessment methodologies at Cerro Negro volcano, Nicaragua, and how volcanic risks are being evaluated and compared with other risks in the YMRP. Staff also began preparations for the NRC Annual Review of the CNWRA and the Fall AGU meeting.

In the next period, staff will (i) make presentations at the NRC Annual Review of the CNWRA, (ii) complete preparations for presentations at the Fall AGU meeting, (iii) continue to analyze and model data from the August activity at the Cerro Negro volcano, and (iv) conduct analog experiments of magma-repository interactions that evaluate the response of a high-volatile content system during sudden decompression and fragmentation.

1.4 Structural Deformation and Seismicity (SDS)

The EarthVision geologic model that will be used as input for hydrologic modeling of the SZ, and the accompanying CNWRA report are being reviewed.

Staff continued an analysis of the field data on faults and fractures recently collected in the Volcanic Tablelands of California. The deformation of the Tablelands serves as an analog for deformation at YM. Results of the analysis will be used in resolving uncertainties in

3

orientation and distribution of fracture sets at YM and in the review and evaluation of the faulting models proposed in the DOE PSHA expert elicitation.

Staff continued development of the Strain Distribution and Tectonic Setting of Yucca Mountain and Crater Flat-Journal Article. This article will evaluate the geological relationships in Crater Flat and present a 3D model of the fault system at Bare Mountain. Alternatives of the model will be used to evaluate sensitivities of the potential seismic hazard at YM.

Paleomagnetic measurements of 136 samples from southern Crater Flat and the Volcanic Tablelands were completed during this period. Analysis of the data will be accomplished during the next several periods.

Staff finished and placed in review an AI report on the portability of SEISM 1.1. This report documents the completion of all SEISM 1.1 activities, including archiving the software.

In the next period, staff will (i) make presentations at the NRC Annual Review of the CNWRA; (ii) modify and add to the 3DStress software leading to Version 2.0, following completion of the TOP-018 requirements; and (iii) continue work on two milestones (the Strain Distribution and the Tectonic Setting Yucca Mountain and Crater Flat-Journal Article and Resolve Selective Field Relationships for the Three-Dimensional Structural Model of Amargosa Desert for Input to the USFIC-CNWRA Report).

1.5 Evolution of the Near-Field Environment (ENFE)

Staff completed the author-final draft of an analysis of ENFE-relevant content in the DOE database of FEPs, focusing on inclusiveness and FEPs screening.

NRC and CNWRA staffs continued a review of the DOE Disposal Criticality Analysis Methodology Topical Report. Staff attended a meeting at Bettis Atomic Power Laboratory, West Mifflin, Pennsylvania, with technical staff from the DOE Naval Nuclear Propulsion Program.

Staff participated in the NRC/CNWRA workshop on the third laboratory-scale heater test held at TWFN. A work plan to model coupled THC processes in the laboratory tests was developed and presented.

A poster titled Hydrothermal or Deuteric Alteration of Tuffs at the Paiute Ridge Intrusive Complex, Nevada, was presented at the Annual Meeting of the GSA in Denver, Colorado. Manuscripts and presentation material were prepared for two papers to be presented at the upcoming Materials Research Society Fall Meeting in Boston, Massachusetts. The papers are Thermodynamic Interpretations of Chemical Analyses of Unsaturated Zone Water from Yucca Mountain, Nevada, and Natural Analogs and Performance Assessment for Geologic Disposal of Nuclear Waste.

Staff continued development of the MULTIFLO code, focusing on release of Version 1.2. Staff also began revisions to the MULTIFLO User's Manual.

4

In addition to an assessment of the potential radiolysis effects on the near-field environment-inside and outside the WP--on the basis of the EDA II design, staff pursued the development of a webpage for the Pefia Blanca natural analog site. A draft of the webpage contents was sent to NRC staff.

Staff prepared presentations for the NRC Annual Review of the CNWRA.

In the next period, staff will (i) submit the report on FEPs Database Analysis; (ii) present results of ENFE activities at the Materials Research Society Fall Meeting in Boston, Massachusetts; (iii) begin SER on the DOE Disposal Criticality Analysis Methodology Topical Report; and (iv) participate in the NRC Annual Review of the CNWRA, December 7-9, 1999 in San Antonio, Texas.

1.6 Container Life and Source Term (CLST)

Staff continued to evaluate the applicability of repassivation and corrosion potentials as adequate electrochemical parameters to predict the long-term, localized corrosion of corrosion-resistant container materials through prolonged corrosion testing. Potentiostatic and open-circuit tests continued, conducted in chloride-containing solutions at 95 'C using Alloy 825 specimens with attached crevice-forming devices. The total test times reached 1,514 and 1,368 days, respectively. In addition, for the past several months, three creviced Alloy 22 specimens have been tested at 95 'C in a 4 M NaC1 solution at pH 8.0. Two of these specimens are being tested at 300 and 400 mVsCE, and the third at the open-circuit potential in an air-saturated solution. The time-dependent changes in the corrosion potential are monitored in the test under open-circuit conditions.

Staff measured the passive corrosion rates of welded Alloy 22 specimens in slightly alkaline (pH 8.2) and acidic (pH 2.7) chloride solutions at 95 'C. Having begun tests to measure the passive corrosion rate of welded specimens in highly alkaline solutions (pH 11.0), results obtained to date indicate that the passive dissolution rate of the welded material is similar to that measured for the base metal. Staff began modeling the passive behavior of Ni-Cr-Mo alloys using a modified version of the point-defect model to provide a solid mechanistic interpretation to the experimentally measured long-term passive corrosion rates.

Staff continued the SCC testing of Alloy 22 and type 316L SS in hot chloride-containing solutions. Fatigue precracked, wedge-loaded DCB specimens of each material were tested in a deaerated 5 percent NaCl solution, acidified to pH 2.7 by the addition of HCI, and heated to 90 'C to duplicate experimental conditions used at the LLNL. No cracking of the two alloys was observed under these conditions for a cumulative test time of 51 wk. In addition, no crack growth was observed on Alloy 22 specimens exposed to a more aggressive environment, 40 percent MgCI2 solution at 110 'C under open-circuit potential conditions. In contrast, significant crack growth was observed in type 316L SS specimens after a short exposure period in MgC12 solutions (both 30 and 40 percent) at 110 'C. Tests of type 316L SS specimens conducted at various applied potentials in 30 percent MgC12 solution at 110 'C showed that the crack growth rate decreases with decreasing potential. It appears that no SCC propagation would occur below the repassivation potential. Staff are planning more tests to confirm whether the repassivation potential may be used as a

5

threshold criterion for precracked specimens as was demonstrated previously for smooth specimens in slow strain rate tests.

Staff prepared a paper containing the results obtained in all these studies on Alloy 22 for presentation at the NACE Corrosion/2000 conference. This paper is currently under programmatic review.

Staff also attended a workshop on life prediction of engineered structures subject to corrosion that was sponsored by the ASTM in Kansas City, Missouri. They made a presentation at this workshop showing how experimental results were used in the TPA code to predict corrosion lifetimes of WP materials. Included in the presentation were examples of the effects of Ni base alloy selection (Alloy 825 vs 625 vs 22) as well as fabrication effects on the localized and uniform corrosion resistance and, consequently, predicted life times of WPs. Staff are preparing a trip report describing the presentation.

Staff evaluated the effects of environmental variables on the corrosion behavior of Ti-grade 7 (identified by the DOE as a possible candidate material for drip shield construction). Long-term tests continued to confirm the high resistance of these alloys to localized corrosion. The galvanic coupling of Ti to carbon steel is also being examined because carbon steel components may be used for ground support, which may lead to conditions favorable for hydrogen embrittlement. Limited crevice corrosion testing continued at temperatures greater than 100 'C to examine the effects of temperature on the critical potentials for the localized corrosion of Ti. Given the high resistance of Ti alloys to localized corrosion, staff conducted measurements of the passive dissolution rate. In addition, welded specimens are being evaluated to examine the possible detrimental effects of weldments on corrosion resistance. A paper to be presented at the NACE Corrosion/2000 conference detailing the results obtained to date is currently being finalized, incorporating technical and programmatic reviews comments.

Another paper for presentation at the NACE Corrosion/2000 conference is being finalized for submission. The topic of the paper is Localized Corrosion Behavior of Zircaloy-4, and it is based on collaborative work conducted by NRC and CNWRA staffs.

Staff pursued testing glass wasteforms using the standard EA glass and two simulated waste glasses (DWPF Blend 1 and WVNS Reference 6) using the ASTM PCT, Method B. Long-term tests on these three glasses are conducted in deionized water and concentrated FeC12 and FeC13 solutions (0.25 and 0.0025 M), with solution replacements twice a week for the first 12 wk using PFA TFE-flourocarbon vessels. A 1-wk solution replacement interval has begun. Twenty-eight solution replacements have been made and the leachates analyzed using ICP to determine the effect of iron cations on the dissolution rate of the reference glasses. This effect is important for assessing the influence of steel corrosion products on glass degradation. In addition, staff used PUF test equipment to study the dissolution behavior of simulated wasteforms under repository conditions. Long-term tests exceeding 6 mo are planned.

Staff continued evaluating the suitability of corrosion potential and chemistry (Cl concentration and pH) sensors for heat transfer conditions as part of a performance confirmation test evaluation program. Results during elevated temperature exposure indicate that the chloride and pH electrodes show promise, though the reference electrode

6

shows some variability with time and solution chemistry. Examination began of the effects of episodic dryout and rewetting on the performance of these electrodes. Based on limited testing, the pH and chloride electrodes seem to perform reasonably. The choice of a suitable reference electrode is still problematic. The results obtained to date were presented at an NRC/CNWRA workshop on the third laboratory-scale heater test at TWFN.

In the next period, staff will (i) participate in the NRC Annual Review of the CNWRA; (ii) pursue long-term corrosion testing of Alloys 825 and C-22 together with SCC tests using Alloy C-22 and type 316L SS along with the Ti-grade 7 test program, including examination of localized corrosion of welded specimens; (iii) examine the effect of preoxidation on the passive film and subsequent corrosion behavior of Zircaloy-4; (iv) evaluate sensor designs to be used in the simulated drift experiments; (v) perform additional glass-dissolution tests; and (vi) begin an investigation of the internal WP environment in coordination with other CNWRA staff associated with the ENFE and TEF KTIs. In addition, technical and programmatic reviews will be completed on the various papers submitted for presentation at the Corrosion/2000 conference and for subsequent publication.

1.7 Thermal Effects on Flow (TEF)

The NRC/CNWRA workshop on the third laboratory-scale heater test was held November 9, 1999, at TWFN. CNWRA representatives from the TEF, ENFE, and CLST KTIs led discussions on test design, test objectives, and details of instrumentation. NRC staff attending the workshop provided valuable input on the design of the experiment that addressed important objectives. Alpine miner muck from the lower lithophysal unit of the Topopah Spring Tuff in the ECRB is being prepared for the experiment.

Staff completed preliminary calculations of temperature and RH inside a backfilled drift and in fractured rock adjacent to the drift wall. These calculations were made available to colleagues in the ENFE KTI. In addition, one TEF KTI staff member attended the Ninth Thermal Workshop held at SNL in Albuquerque, New Mexico. He submitted a trip report summarizing discussions regarding the DST and concerns regarding heat and moisture loss through the thermal bulkhead.

Laboratory investigation is ongoing of an artificial fracture to determine whether or not a capillary threshold for dripping exists for preferential "finger" flow along a fracture at the drift wall boundary. Preliminary TH simulations of the DST in 3D are progressing to investigate the effects of moisture and heat loss through the thermal bulkhead on the development of refluxing above the heated drift. Simulations of mountain-scale and driftscale TH are continuing to look at the effects of repository edge cooling and preclosure ventilation.

In the next period, staff plan to (i) make presentations at the NRC Annual Review of the CNWRA; (ii) provide results of capillary diversion in an artificial fracture at the Fall Meeting of the AGU; and (iii) continue 3D modeling of the DST and 2D modeling of TH at the drift and mountain scales.

1.8 Repository Design and Thermal-Mechanical Effects (RDTME)

The ABAQUS code modeling of WPs continued to investigate the thermal stress of WPs and assess the WP responses when subjected to the impact of falling rocks at various times considering the long-term effect of corrosion on WPs. This analysis will develop a reasonable failure criterion for use in the SEISMO module to assess the effect of rockfalls on WP integrity.

Staff began a discontinuous analysis using the UDEC code to assess the stability of emplacement drifts under the newly proposed EDA II. The analysis focused on the effect of data input uncertainties on rock-mass behavior surrounding the emplacement drifts. The data under consideration include both mechanical and strength properties. The effect of lithophysae also will be included in the analysis in the future. In addition, staff pursued efforts to examine rockfall potential using the Key Block Theory considering thermal stress and seismic loads.

Development activities related to the ISA prediction tool began. During this reporting period, activities focused on (i) identifying computer codes suitable for conducting various aspects of the analysis and (ii) becoming familiar with the ISA process so that appropriate acceptance criteria and review methods can be developed for review of the DOE ISA in the LA. Modeling work started on one subtask of the DECOVALEX mI Program. This subtask is part of Task 2 (Drift Scale Test at the Yucca Mountain) of the DECOVALEX III Program.

One RDTME staff member attended the Ninth Thermal Workshop held at SNL in Albuquerque, New Mexico. Staff participated in the Appendix 7 Meeting on QA Classification and ISA Approach held in Las Vegas, Nevada, November 16, 1999, and the Appendix 7 Meeting on Ground Control held in Las Vegas, Nevada, November 17-18, 1999.

In the next period, staff plan to (i) make presentations at the NRC Annual Review of the CNWRA; (ii) investigate rock mass behavior under heated conditions on both repository and drift scales with an emphasis on long-term degradation of rock mass material properties and strengths using the new EDA II design; (iii) conduct rockfall simulations; (iv) use the ABAQUS code to model WPs; (v) model the TMH coupled effects for the DECOVALEX III Program; (vi) participate in the NRC Annual Review of the CNWRA; and (vii) attend the DECOVALEX III Task Force Meeting to be held in Barcelona, Spain, December 13-15, 1999.

1.9 Total System Performance Assessment and Integration (TSPAI)

Staff continued testing the TPA Version 3.3 code and preparing documents for software configuration control. The CNWRA and the NRC PA staffs finalized the prioritization of the TPA Version 4.0 code process-level changes proposed by staff associated with the various KTIs. The CNWRA PA staff proposed additional system-level changes. Also, the CNWRA staff began developing the SRD for the TPA Version 4.0 code. In support of SRD development, staff conducted feasibility studies using the TPA code to identify code changes needed to accommodate the DOE new repository and WP designs.

8

The report, External Peer Review of the Total-system Performance Assessment Version 3.2 Code, was submitted. The report compiles the independent reports from each of the eight external peer reviewers and summarizes their findings on the suitability of the TPA Version 3.2 code as a tool for reviewing the DOE TSPA-LA. Staff will use the comments of the external reviewers to guide the development of future versions of the TPA code.

The CNWRA and NRC staffs continued revising Input to TSPAI IRSR, Revision 2-Letter Report based on new guidance received from the NRC for a systematic, logical, and easyto-read style of presentation. The draft version of the section on transparency and traceability in the performance assessment was completed, provided to the NRC staff for review, and submitted for incorporation into the TSPAI IRSR.

Staff made two presentations at the ANS Winter Meeting, held November 14-19, 1999, in Long Beach, California. Staff also traveled to Rockville, Maryland, to attend the 114th

ACNW Meeting and discuss with subcontractor staff the development of a post-processor for the systematic presentation of TPA output. Other activities during this period include preparation of papers for the NRC-approved presentations at the Waste Management 2000 Conference to be held February 28-March 2, 2000, in Tucson, Arizona, and the European Safety and Reliability Conference (ESREL2000) scheduled for May 15-17, 2000, in Edinburgh, Scotland, United Kingdom.

Four papers were submitted during this period for NRC programmatic review. Two of these papers will be published in the proceedings of the Scientific Basis for Nuclear Waste Management Symposium scheduled for November 29-December 3, 1999, in Boston, Massachusetts. The other two will be submitted for publication in the Nuclear Engineering and Design journal.

In the next period, the staff will focus on (i) participating in the NRC Annual Review of the CNWRA on December 7-9, 1999, at San Antonio, Texas; (ii) completing Input to TSPAI IRSR, Revision 2-Letter Report; (iii) finalizing testing and documentation documents for the TPA Version 3.3 code; (iv) discussing with staff in other KTIs changes to be implemented in the TPA Version 4.0 code and preparing the associated SRD and SDP; (v) preparing papers for conferences; and (vi) beginning work on the strategic plan for review of the TSPA-SR. Two PA staff will join the CNWRA in the January-February timeframe; active recruitment for the two remaining PA positions will be postponed until later in the year.

1.10 Activities Related to Development of the NRC High-Level Waste Regulations (ARDR)

Staff continued writing responses to public comments on the 10 CFR Part 63 proposed rule. They also continued consideration of potential changes to the Statements of Consideration and this proposed rule based on review of the comments.

In the next period, emphasis will be placed on (i) participating in the NRC Annual Review of the CNWRA on December 7-9, 1999 at San Antonio, Texas; (ii) completing draft responses to the NRC comments on the proposed 10 CFR Part 63 and the identification of potential changes to the proposed rule and the Statements of Consideration that result from the responses to public comments; and (iii) conducting analyses supporting these responses

9

to public comments needed for the upcoming deliverable, Analyses Supporting Responses to Public Comments on Draft HLW Rulemaking.

1.11 Unsaturated and Saturated Flow Under Isothermal Conditions (USFIC)

Staff pursued watershed modeling, using existing data and recent confirmatory field observations of soil cover and bedrock lithology, in an effort to investigate the alternative conceptual model of high, focused infiltration in the upper watershed caused by focusing of runoff into channels and the thin alluvial cover in those channels.

Staff also continued modeling analyses to assess the importance of well-screen length, dispersivity, source mixing, and plume geometries on dilution of contaminants in pumping wells. Because and DOE is likely to take credit for well-bore dilution, these analyses will allow staff to rank the importance of various controlling factors and focus review efforts accordingly.

SZ flow modeling was used to test the alternative conceptual model of enhanced permeability along fault zones and reduced permeability across fault zones. Inclusion of such characteristics in the flow model resulted in improved model calibration. In a parallel effort, reduction of YM well data continued in the ongoing review of aquifer permeability and the potential for increased permeability along faults.

Staff continued to review pertinent DOE reports, literature, meeting transcripts, and data. One staff member attended a meeting in Beatty, Nevada, on the development of the USGS Death Valley Regional Groundwater Flow.Model.

In the next period, USFIC activities will include (i) delivery of a presentation at the NRC Annual Review of the CNWRA on December 7-9, 1999 in San Antonio, Texas; (ii) participation in the AGU Fall Meeting, December 13-17, 1999, in San Francisco, California; (iii) review of DOE models for seepage and dripping in underground cavities; (iv) analysis of processes affecting deep percolation; (v) analysis of YM well data; and (vi) continued use of a site-scale model for SZ flow to investigate alternative conceptual models for flow.

1.12 Radionuclide Transport (RT)

Staff presented an invited paper, Role of Radionuclide Sorption in High-Level Waste Performance Assessment: Approaches for the Abstraction of Detailed Models, at the Soil Science Society of America Annual Meeting held October 31-November 5, 1999, in Salt Lake City, Utah. Staff completed the manuscript, Technetium-99 Chemistry in Reducing Groundwaters: Implications for the Performance of a Proposed High-Level Nuclear Waste Repository at Yucca Mountain, Nevada, for presentation at the Materials Research Society Annual Meeting to be held in Boston, Massachusetts, November 29-December 3, 1999. Staff prepared presentation materials for the NRC Annual Review of the CNWRA to be held December 7-9, 1999, in San Antonio, Texas.

Experiments continued on the sorption behavior of Tc and coprecipitation for Np and calcite. The effect of calcite growth rate on Np coprecipitation, as controlled by supersaturation with respect to calcite, is being studied. XAFS spectra were collected at

10

Brookhaven National Laboratory for investigating mechanisms for uranyl sorption onto montmorillonite and clinoptilolite. Analyzed samples include ion-exchanged and surfaceadsorbed uranyl ion with clinoptilolite and montmorillonite, reacted at pH 3 and 6, respectively.

Staff participated in the November sampling event for the Nye County EWDP wells. Samples from well NC-EWDP-3S were collected from the 408 ft and 500 ft sampling ports and were analyzed for temperature, pH, conductivity, oxidation-reduction potential, and alkalinity. The samples are being processed for further chemical analyses.

In the next period, staff will (i) make a presentation at the NRC Annual Review of the CNWRA, (ii) work with staff associated with the TSPAI KTI to implement proposed sorption response surfaces for the TPA Version 4.0 code, (iii) continue to revise reports on ion exchange and surface complexation, and (iv) pursue sorption experiments on alluvium minerals.

1.13 Review of the Draft Environmental Impact Statement (DEIS)

Staff and external consultants completed review of the DOE DEIS for the proposed repository and submitted Draft Environmental Impact Statement Evaluative Review Comments. The CNWRA staff participated in public meetings in Caliente, Nevada, and attended a DEIS briefing to the ACNW.

In the next period, the staff and external consultants will work with the NRC staff to finalize DEIS comments for submission to the Commission.

1.14 Public Outreach

Discussions continued with a risk communications expert about conducting a 1- or 2-day course at the CNWRA. Although a date for this course still has not been established, staff believes it can be conducted by the end of period 5.

In the next period, efforts will continue to establish a schedule and agenda for the short course on risk communications.

1.15 Development of the Yucca Mountain Review Plan (YMRP)

YMRP development continued in collaboration with the NRC staff. KTI and ISI staff leads continued preparation of the model abstraction portions of the plan, and some ISI sections completed the internal CNWRA review process. Staff proceeded on the preclosure and QA portions of the plan. The CNWRA project manager participated in a presentation to the ACNW on YMRP development. An Annotated Yucca Mountain Review Plan Outline was prepared for submittal as an IM during the next period.

In the next period, staff will continue development of Revision 0 of the YMRP, focusing on completion of the postclosure safety sections. The CNWRA project manager will participate in meetings with NRC staff and management at TWFN. Development of the preclosure safety and administrative and programmatic portions of the YMRP will also continue. The CNWRA will draft a white paper that proposes options for the integration

11

of the IRSR and the YMRP structures. The CNWRA will also identify activities that should be conducted under YMRP development rather than under the KTIs to address an existing resource imbalance. The Annotated Yucca Mountain Review Plan outline will be submitted.

1.16 Tank Waste Remediation System (TWRS)

In subtask 1.2, staff started work on the technical review report on Ultrafilters. Also, staff is reformatting the Survey of Solidification Technologies report to NUREG/CR format and awaiting copyright permissions for figures and tables from authors and publishers.

In subtask 1.4, staff started work on the classification and categorization of process safety issues.

In subtask 1.6, staff continued development of a spreadsheet model of the pretreatment process, based on mass-balance considerations using reported waste feed envelope compositions and reported or assumed concentration factors or decontamination factors. A preliminary version was sent.

In subtask 2.1, CNWRA staff attended a topical meeting on Cs storage vessel cooling and seismic probabilistic risk analysis and a design review meeting on low activity waste and high-level waste melter design. CNWRA staff attended a design review meeting on pretreatment ion exchange systems and equipment. Trip reports on these meetings have been transmitted. Staff provided comments to the NRC on the Management of Risks Posed by Explosive Hazards Present at the River Protection Project-Waste Treatment Plant on October 13, 1999. On November 11, 1999, staff provided response to BNFL Inc. comments on the CNWRA document, Review of BNFL Inc. Design Safety Features Deliverable: Hydrogen Control in High-Level Waste Storage Tanks. Staff started review of the BNFL Inc. document entitled Summary of ISM Cycle 1 Results and Identification of Preliminary Design Basis Events. As agreed with the NRC, initial comments will be provided as an AI on November 24, 1999, and final comments by December 21, 1999, after incorporating new information provided by BNFL Inc. at a topical meeting on November 30, 1999.

In the next period, in subtask 1.2, staff will continue work on reformatting the Survey of Solidification Technologies report and the technical review report on Ultrafilters. In subtask 1.4, staff will continue the classification and categorization of process safety issues. In subtask 1.6, development of a spreadsheet model for the TWRS waste pretreatment will progress. In subtask 2.1, staff will review the document, Summary of ISM Cycle 1 Results and Identification of Preliminary Design Basis Events. In addition, staff plan to attend a topical meeting on November 30, 1999, and a design review meeting on December 7-8, 1999.

1.17 Dry Transfer System (DTS)

Development of the DTS draft SER progressed during this period, making use of the CNWRA and SwRI staffs and a consultant. Significant progress was made developing this draft SER. It will be delivered as Safety Evaluation Report of Dry Transfer System Topical Safety Analysis Report-Draft during the next reporting period.

12

In the next period, the staff will complete development of the draft SER.

1.18 Centralized Interim Storage Facility (CISF)

Staff continued reviewing the DOE response to the SFPO first round RAI on the HI-STAR and HI-STORM topical report for high seismic sites. Further, staff began developing the second round RAI.

In the next period, the staff will continue reviewing and evaluating the DOE response to the SFPO first round RAI on the HI-STAR and HI-STORM topical report for high seismic risk

sites. The development of the second round RAI will also be ongoing.

1.19 Private Fuel Storage Facility (PFSF)

Three PFSF staff members visited the site in Utah and participated in the NRC/PFSF

meeting at Salt Lake City, Utah, on revised seismic design. Two PFSF staff members also

attended a meeting with the Air Force staff at Hill Air Force Base to discuss aircraft accident issues. The staff worked interactively with the NRC staff to prepare the public release version of the site-specific portion of the PFSF SER. They also worked on various contentions.

In the next period, the staff plans to continue working interactively with the NRC staff to

prepare the public release version of the site-specific portion of the PFSF SER, review and

evaluate the revised seismic design reports, and assist the NRC staff on ASLB hearing activities.

4 SUMMARY OF SCHEDULE CHANGES

Schedule changes for IMs are included in table 3. Completed deliverables are noted in table 4.

5 SUMMARY OF FINANCIAL STATUS

Table 5 summarizes the CNWRA financial status in the context of authorized funds. Total

commitments are $368,227. The appendix lists planned and actual costs to date, as well as variances

between these, without allowance for fee, on both a per-period and a cumulative basis. These data

do not include commitments. Pertinent financial information is provided for the DWM JC, including

COPS, EQA, DEIS, Public Outreach, YMRP, and ten KTIs, TWRS JC, DTS JC, CISF JC, and PFSF

JC. The planned costs per period are based on the revised spending plans contained in the FY2000 OPS conveyed to the NRC.

13

Period 2 FY2000 CNWRA composite expenditures rose a modest 0.14 percent from last period, and this aggregate of all JCs was overspent by $143,786 or -6.7 percent. Since the previous period, spending rose in the DTS and PFSF JCs, but fell in the DWM, TWRS, and CISF JCs. With the exception of the DWM JC, all other JCs have a positive cumulative variance in period 2.

Expenditures on SwRI labor, consultants, and subcontractors as a proportion of composite spending on all JCs were 19.4 percent. Expense of consultants and subcontractors as a fraction of composite spending on all JCs was 12.1 percent. The CNWRA continues the judicious employment of consultants and subcontractors in the conduct of CNWRA work.

As shown in table 1, the CNWRA has 56 staff members. The available pool of approved consultants and subcontractors is 85.

This FYTD, no capital or sensitive equipment was purchased with NRC funds (other than overhead, general and administrative expenses, and fees).

The DWM JC was overspent by $209,240 or - 11.3 percent. Overall expenditures decreased about 1.4 percent from the previous period as costs rose in the IA, TSPA, and USFIC KTIs as well as the EQA and YMRP, but declined in COPS and the SDS, ENFE, CLST, TEF, RDTME, ARDR, and RT KTIs as well as the DEIS and Public Outreach. With the exception of EQA, Public Outreach, and YMRP, DEIS, COPS, and all ten KTIs have a negative cumulative variance in period 2. In various meetings with NRC senior management staff and other interested parties, CNWRA senior management staff continue to discuss current and expected levels of spending, recruitment efforts for core staff, and effective engagement of consultants and subcontractors. The CNWRA revised its award fee pool and estimate of carryover monies.

The cost variance for COPS was -30.4 percent: -35.7 percent for the Management, Planning, and Computer Support subtask (158) and -2.8 percent for the QA subtask (159). The negative variance in subtask 158 resulted primarily from delayed payment to consultants and subcontractors for FY1999, increased travel and time related to staff professional development, staff travel and time for an NRC/CNWRA Management Meeting, and late payment of costs related to the development and submittal of OPS. In the next period, spending in subtask 158 is expected to decline, but may still exceed the estimated amount. CNWRA management will monitor expenditures to ensure that

the cognizant NRC PEM for COPS is provided sufficient notice concerning expected negative variances from estimated spending in the next couple of periods. In subtask 159, spending decreased in period 2 relative to last period because of a temporary slowdown in the QA surveillance schedule and reduced consultant costs.

The cumulative cost variance for EQA was 34.5 percent. Spending this period exceeded the planned amount because of heavier activities in the field and preparation for additional NRC observation audit teams in the year 2000. In the third period of the FY, spending in subtask 331 is expected to continue near the period 2 level as the two observation audit reports are written and transmitted to the NRC.

The cost variance for the IA KTI was -25.0 percent. This overspending continues to be driven by payment of outstanding charges from FY1999. FY2000 expenditures for external labor will be controlled during the second quarter to bring expenditures within anticipated costs.

14

The cost variance for the SDS KTI was -5.4 percent. The overspending decreased significantly this period and continues to be driven by commitments incurred last FY.

The cost variance for the ENFE KTI was -45.8 percent. Although this variance is a decrease in percentage terms from period 1, the absolute value of the variance increased substantially during this period. This variance is likely to persist until activity under the YMRP increases.

The cost variance for the CLST KTI was -30.4 percent. Per period spending and cumulative variance are down, and, once the startup phase is completed, project spending will be brought in line with budgeted funds during the second quarter.

The cost variance for the TEF KTI was -6.6 percent. This variance is significantly lower than that of the previous period, and will be reduced further during the next period. The FY2000 total expenditures are expected to converge to the FY2000 allocation.

The cost variance for the RDTME KTI was -2.1 percent. FY2000 total expenditures are anticipated to converge to the planned amount.

The cost variance for the TSPAI KTI was -38.1 percent. Spending increased from the first period of FY2000 because of additional work on the modifications to Revision 2 of the TSPAI IRSR. The spending is expected to decrease in the next period following completion of the IRSR and staff vacations during the winter holidays.

The cost variance for the ARDR KTI was - 1.1 percent. Spending should continue at the same pace during the next period to complete the responses to the public comments on 10 CFR Part 63.

The cost variance for the USFIC KTI was -3.4 percent. This small negative variance resulted from an increase in activities relative to period 1. Future costs are likely to be somewhat above planned as a new hydrologist starts work during period 3. Appropriate reduction in use of external labor will be used to bring the project into convergence with the budget.

The cost variance for the RT KTI was -54.0 percent. This represents a significant decrease in the period cost variance from period 1, but the cumulative continued to increase significantly. Costs for consultants and subcontractors from FY1999 posted to this account during period 1 of FY2000 and travel costs are responsible for this variance. The cost variance should be reduced as activities increase related to YMRP development.

The cost variance for review of the DEIS was -31.3 percent. This variance was the result of the concentrated effort by CNWRA staff and external consultants to complete their reviews of the DEIS. The variance is expected to continue to increase through the next period as consultant billings are paid, but spending will then decrease substantially as DEIS review activity slows. This project is ultimately expected to have net underspending, because the level of required travel and consultant support for public meetings is expected to be less than was envisioned in the original statement of work.

The cost variance for Public Outreach was 83.7 percent. This amount understates the actual variance because labor that should have been charged to the DEIS project was inadvertently charged to this account. A transfer of labor will be processed to correct this error. Significant spending is not expected until periods 5 and 6.

15

Although costs more than doubled relative to period 1, the cumulative cost variance for development of the YMRP was 65.4 percent. The large variance is partially due to priority given by the project manager to review of the YM DEIS. The CNWRA is identifying work that can appropriately be shifted to YMRP development from the KTI structure.

The cost variance for the TWRS project was 24.2 percent. The variance will decline when new activities accelerate.

The cost variance for the DTS project was 7.9 percent. This cost variance is considerably less than that of the previous period. The FY2000 total expenditures are expected to converge to the FY2000 allocation.

The cost variance for the CISF project was 43.1 percent. This cost variance is due to lack of assignment from the NRC and lagging charges from a consultant.

The cost variance for the PFSF project was 26.6 percent. This cost variance is because of delay in receiving the final seismic design reports, aircraft crash hazard report, and other submittals from the applicant that have caused rescheduling of the delivery date of the PFSF SER supplement.
