Description and Assessment

1.0 DESCRIPTION

This letter is a request to amend Operating License DPR-72 for Crystal River Unit 3(CR-3).

The proposed changes would replace the current limits on primary coolant gross specificactivity with limits on primary coolant noble gas activity. The noble gas activity wouldbe based on DOSE EQUIVALENT XE-133 and would take into account only the noblegas activity in the primary coolant. The changes were approved by the NuclearRegulatory Commission (NRC) staff Safety Evaluation (SE) dated September 27, 2006(ADAMS ML062700612) (Reference 1). Technical Specification Task Force (TSTF)change traveler TSTF-490, Revision 0, "Deletion of E Bar Definition and Revision toRCS Specific Activity Tech Spec" was announced for availability in the Federal Registeron March 19, 2007 (72 FR 12838) as part of the consolidated line item improvementprocess (CLIIP).

2.0 PROPOSED CHANGES

Consistent with NRC-approved TSTF-490, Revision 0, the proposed ITS changes are asfollows:* Revise the definition of DOSE EQUIVALENT 1-13 1.* Delete the definition of"E Bar, AVERAGE DISINTEGRATION ENERGY.* Add a new TS definition for DOSE EQUIVALENT XE-133.* Revise LCO 3.4.15, "RCS Specific Activity" to delete references to gross specific

activity; add limits for DOSE EQUIVALENT 1-131 and DOSE EQUIVALENTXE-133; and delete Figure 3.4.15-1, "Reactor Coolant DOSE EQUIVALENT 1-131Specific Activity Limit versus Percent of RATED THERMAL POWER."

* Revise LCO 3.4.15 "Applicability" to specify the LCO is applicable in MODES 1, 2,3, and 4.

* Modify ITS 3.4.15 ACTIONS Table as follows:A. Condition A is modified to delete the reference to Figure 3.4.15-1, and define an

upper limit that is applicable at all power levels.B. ACTIONS are reordered, moving Condition C to Condition B to be consistent

with the Writer's Guide.C. Condition B is modified to provide a Condition and Required Action for DOSE

EQUIVALENT XE-133 instead of gross specific activity. The Completion Timeis changed from 6 hours to 48 hours. A Note allowing the applicability of LCO3.0.4.c is added, consistent with the Note to Required Action A. 1.

D. Condition C is modified based on the changes to Conditions A and B and toreflect the change in the LCO Applicability.

* Revise. SR 3.4.15.1 to verify the limit for DOSE EQUIVALENT XE-133. A Note isadded, consistent with SR 3.4.15.2 to allow entry into MODES 2, 3, and 4 prior toperformance of the SR.

* Delete SR 3.4.15.3.

3.0 BACKGROUND

The background for this application is as stated in the model SE in NRC's Notice ofAvailability published on March 19, 2007 (72 FR 12838), the NRC Notice for Commentpublished on November 20, 2006 (71 FR 67170), and TSTF-490, Revision 0.

4.0 TECHNICAL ANALYSIS

In the model SE, the NRC included statements that would require Florida PowerCorporation (FPC) to identify specific information in support of adopting TSTF-490.The following provides the CR-3 specific information in this regard.

1. Section 3.1.1 of the model SE includes a list of acceptable dose conversion factors(DCF) for use in the determination of dose equivalent iodine (DEI) in relation to doseconsequence analysis. The CR-3 analyses employ Committed Effective DoseEquivalent (CEDE) dose conversion factors from Table 2.1 of EPA Federal GuidanceReport No. 11, "Limiting Values of Radionuclide Intake and Air Concentration andDose Conversion Factors for Inhalation, Submersion, and Ingestion."

2. In the first paragraph of Section 3.1.2 of the Model SE, a bracketed list of isotopes isprovided that designates the noble gases that may be used in the determination ofdose equivalent xenon (DEX). All isotopes depicted within these brackets arecurrently considered in the CR-3 calculation of, DEX. This is reflected in theproposed CR-3 definition Of DEX.

3. Section 3.1.2 of the model SE also provides two possible determination methods forDEX. CR-3 uses the effective dose conversion factors for air submersion listed inTable 111.1 of EA Federal Guidance Report No. 12, 1993, "External Exposure toRadionuclides in Air, Water, and Soil." This is also reflected in the proposed CR-3definition of DEX.

4. Section 3.1.3 of the model SE states that it is incumbent on the licensee to ensure thatthe site specific limits for both DEI and DEX are consistent with the current steamgenerator tube rupture (SGTR) and main steam line break (MSLB) radiologicalconsequence analyses. CR-3 is requesting this LAR for post EPU conditions whichwill be 0.35 ýiCi/g for DEI and 646 gCi/g for DEX as depicted in the proposed CR-3ITS pages. These proposed changes will be implemented prior to the end of Refuel17, scheduled for Fall 2011.

FPC, doing business as Progress Energy Florida, Inc., has reviewed References 1, 2 and3, and the model SE published on November 20, 2006 (71 FR 67170) as part of theCLIIP Notice for Comment. FPC has applied the methodology in Reference 1 to developthe proposed TS changes. FPC has also concluded that the justifications presented inTSTF-490, Revision 0, and the model SE prepared by the NRC staff are applicable toCR-3, and justify this amendment for the incorporation of the changes to the CR-3Improved Technical Specifications (ITS).

RCS Specific Acti vi tyB 3.4.15

B 3.4 REACTOR COOLANT SYSTEM (RCS)

B 3.4.15 RCS Specific Activity

BASES

BACKGROUND The maximum dose that an individual at the exclusion areaboundary can receive for 2 hours following an accident, or atthe low population zone outer boundary for the radiologicalrelease duration, is specified in 10 CFR 50.67 (Ref. 1). Dosesto control room operators must be limited per GDC 19. Thelimits on specific activity ensure that the offsite and controlroom doses are appropriately limited during analyzed transientsand accidents.

The RCS specific activity LCO limits the allowableconcentration level of radionuclides in the reactor coolant.The LCO limits are established to minimize the doseconsequences in the event of a steam line break (SLB) or steamgenerator tube rupture (SGTR) accident.

The LCO contains specific activity limits for both DOSEEQUIVALENT 1-131 and DOSE EQUIVALENT XE-133. The allowablelevels are intended to ensure that offsite and control roomdoses meet the appropriate acceptance criteria in the StandardReview Plan (Ref. 2).

APPLICABLESAFETY ANALYSES

The LCO limits on the specific activity of the reactorcoolant ensure that the resulting offsite and control roomdoses meet the appropriate SRP acceptance criteriafollowing a SLB or SGTR accident. The safety analyses(Refs. 3 and 4) assume the specific activity of the reactorcoolant is at the LCO limits, and an existing reactorcoolant steam generator (SG) tube leakage rate of 1.0 gpmexists. The safety analyses assume the specific activityof the secondary coolant is at its limit of 4.5E-4 pCi/gDOSE EQUIVALENT 1-131 from LCO 3.7.16, "Secondary SpecificActivity."

The analyses for the SLB and SGTR accidents establish theacceptance limits for RCS specific activity. Reference tothese analyses is used to assess changes to the unit thatcould affect RCS specific activity, as they relate to theacceptance limits.

RCS Specific ActivityB 3.4.15

BASES

APPLICABLESAFETY ANALYSES(continued)

The safety analyses consider two cases of reactorcoolant iodine specific activity. One case assumesspecific activity at 0.35 pCi/g DOSE EQUIVALENT 1-131 witha concurrent large iodine spike that increases the rate ofrelease of iodine from the fuel rods containing claddingdefects to the primary coolant immediately after a SLB (bya factor of 500), or SGTR (by a factor of 335),respectively. The second case assumes the initial reactorcoolant iodine activity at 21.0 pCi/g DOSE EQUIVALENT 1-131due to an iodine spike caused by a reactor or an RCStransient priorto the accident. In both cases, the noblegas specific activity is assumed to be 646 pCi/g DOSEEQUIVALENT XE-133.

The SGTR analysis assumes a rise in pressure in theruptured SG causes radioactively contaminated steam todischarge to the atmosphere through the atmospheric dumpvalves or the main steam safety valves. The atmosphericdischarge stops when the turbine bypass to the condenserremoves the excess energy to rapidly reduce the RCSpressure and close the valves. The unaffected SG removescore decay heat by venting steam until the cooldown endsand the Decay Heat Removal (DHR) system is placed inservice.

The SLB radiological analysis. assumes that offsite power islost at the same time as the pipe break occurs outsideContainment. The affected .SG blows down completely andsteam is vented directly to the atmosphere. The unaffectedSG removes core decay heat iby venting steam to theatmosphereunt'il the cooldown:ends and the DHR system isplaced in service.

Operation with iodine specific activity levels greater thanthe LCO limit is permissible, if the activity levels do notexceed 21.0 pCi/g for more than 48 hours.

The limits on RCS specific activity are also used forestablishing standardization in radiation shielding andplant personnel radiation protection practices.

RCS specific activity satisfies Criterion 2 of 10 CFR50.36(c) (2) (ii).

LCO The iodine specific activity in the reactor coolant islimited to 0.35 pCi/g DOSE EQUIVALENT 1-131, and the noblegas specific activity in the reactor coolant is limited to646 pCi/g DOSE EQUIVALENT XE-133. The limits on specificactivity ensure that offsite and control room doses willmeet the appropriate SRP acceptance criteria (Ref. 2).

The SLB and SGTR accident analyses (Refs. 3 and 4) show

RCS Specific ActivityB 3.4.15

BASES

LCO that the calculated doses are within acceptable limits.(continued) Violation of the LCO may result in reactor coolant

radioactivity levels that could, in the event of a SLB orSGTR, lead to doses that exceed the SRP acceptance criteria(Ref. 2).

APPLICABILITY In MODES 1, 2, 3, and 4, operation within the LCO limitsfor DOSE EQUIVALENT 1-131 and DOSE EQUIVALENT XE-133 isnecessary to limit the potential consequences of a SLB orSGTR to within the SRP acceptance criteria (Ref. 2).

In MODES 5 and 6, the steam generators are not being usedfor decay heat removal, the RCS and steam generators aredepressurized, and primary to secondary leakage is minimal.Therefore, the monitoring of RCS specific activity is notrequi red.

ACTIONS A.1 and A.2

With the DOSE EQUIVALENT 1-131 greater than the LCO limit,samples at intervals of 4 hours must be taken todemonstrate that the specific activity is < 21.0 pCi/g.The Completion Time of 4 hours is required to obtain andanalyze a sample. Sampling is continued every 4 hours toprovide a trend.

The DOSE EQUIVALENT 1-131 must be restored to within limitwithin 48 hours. The Completion Time of 48 hours isacceptable since it is expected that, if there were aniodine spike, the normal coolant iodine concentration wouldbe restored within this time period. Also, there is a lowprobability of a SLB or SGTR occurring during this timeperiod.

A Note permits the use of the provisions of LCO 3.0.4.c.This allowance permits entry into the applicable MODE(S),relying on Required Actions A.1 and A.2 while the DOSEEQUIVALENT 1-131 LCO limit is not met. This allowance isacceptable due to the significant conservatism incorporatedinto the specific activity limit, the low probability of anevent which is limiting due to exceeding this limit, andthe ability to restore transient-specific activityexcursions while the plant remains at, or proceeds to,power operation.

BASES

ACTIONS B.1(continued)

With the DOSE EQUIVALENT XE-133 greater than the LCO limit,DOSE EQUIVALENT XE-133 must be restored to within limitwithin 48 hours. The allowed Completion Time of 48 hoursis acceptable since it is expected that, if there were anoble gas spike, the normal coolant noble gas concentrationwould be restored within this time period. Also, there isa low probability of a SLB or SGTR occurring during thistime period.

A Note permits the use of the provisions of LCO 3.0.4.c.This allowance permits entry into the applicable MODES(S),relying on Required Action B.1 while the DOSE EQUIVALENTXE-133 LCO limit is not met. This allowance is acceptabledue to the significant conservatism incorporated into thespecific activity limit, the low probability of an eventwhich is limiting due to exceeding this limit, and theability to restore transient-specific activity excursionswhile the plant remains at, or proceeds to, poweroperation.

C.1 and C.2

If the Required Action and associated Completion Time ofCondition A or B is not met, or if the DOSE EQUIVALENT1-131 is > 21.0 pCi/g, the reactor must be brought to MODE3 within 6 hours and MODE 5 within 36 hours. The allowedCompletion Times are reasonable, based on operatingexperience, to reach the required plant conditions fromfull power conditions in an orderly manner and withoutchallenging plant systems.

SURVEILLANCE SR 3.4.15.1REQUIREMENTS

SR 3.4.15.1 requires performing a gamma isotopic analysisas a measure of the noble gas specific activity of thereactor coolant at least once every 7 days. Thismeasurement is the sum of the degassed gamma activities andthe gaseous gamma activities in the sample taken. ThisSurveillance provides an indication of any increase in thenoble gas specific activity.

BASES

SURVEILLANCE SR 3.4.15.1 (continued)REQUIREMENTS

Trending the results of this Surveillance allows properremedial action to be taken before reaching the LCO limitunder normal operating conditions. The 7 day Frequencyconsiders the low probability of a gross fuel failureduring this time.

Due to the inherent difficulty in detecting Kr-85 in areactor coolant sample due to masking from radioisotopeswith similar decay energies, such as F-18 and 1-134, it isacceptable to include the minimum detectable activity forKr-85 in the SR 3.4.15.1 calculation. If a specific noblegas nuclide listed in the definition of DOSE EQUIVALENTXE-133 is not detected, it should be assumed to be presentat the minimum detectable activity.

A Note modifies the SR to allow entry into and operation inMODE 4, MODE 3, and MODE 2 prior to performing the SR.This allows the Surveillance to be performed in thoseMODES, prior to entering MODE 1.

SR 3.4.15.2

This Surveillance is performed to ensure iodine specificactivity remains within the LCO limit during normaloperation and following fast power changes when iodinespiking is more apt to occur. The 14 day Frequency isadequate to trend changes in the iodine activity level,considering noble gas activity is monitored every 7 days.The Frequency, between 2 and 6 hours after a power change> 15% RTP within a 1 hour period, is established becausethe iodine levels peak during this time following iodinespike initiation; samples at other times would provideinaccurate results.

The Note modifies this SR to allow entry into and operationin MODE 4, MODE 3, and MODE 2 prior to performing the SR.This allows the Surveillance to be performed in thoseMODES, prior to entering MODE 1.
