1.0 INTRODUCTION

1.1 PURPOSE

This Waste Analysis P lan (WAF) provides the plan for obtaining information needed for proper waste hand l ing and processing i n the 242-A Evaporator (Evaporator) located on the Hanford Site. manage the waste according t o Washington Administrat ive Code (WAC) 173-303 and Parts 264 and 265 of the Code o f Federal Regulations (CFR) . Regulatory and safety issues are addressed by establishing boundary conditions for waste received and treated a t the 242-A Evaporator. The boundary conditions are set by establishing limits for items such as potential exothermic reactions, waste compatibility. and control o f vessel vent organic emi ssi ons , considerations and t o ensure waste acceptance a t receiving fac i l i t i es .

In particular i t addresses analysis necessary t o

Boundary conditions are a1 so set for operational

1.2 SCOPE

The issues t h a t are addressed i n this p l a n include prevention of exotherms i n the waste, waste compati bi 1 i t y , and vessel vent emissions. Samples from the other streams associated w i t h the Evaporator are taken as required by Process Control Plans b u t are excluded from this plan because either the streams do not contain dangerous waste or the analyses are not required by WAC 173-303-300.

2.0 FACILITY AND PROCESS DESCRIPTION

The 242-A Evaporator is located i n the 200 East Area of the Hanford Site. This Evaporator separates the waste i n t o three components as described i n the following paragraph. Also associated w i t h this Evaporator are u t i l i t y waste streams such as cooling water and steam condensate. The types of wastes processed by the Evaporator are described i n Section 3.0.

The 242-A Evaporator process uses a conventional forced circulation and vacuum evaporation system t o concentrate mixed waste solutions. The 242-A Evaporator feed stream is separated i n t o two l i q u i d streams: a concentrated slurry stream and a process condensate. A gaseous exhaust stream is also produced. The slurry contains the majority o f the radi onucl i des and inorganic constituents . This stream i s pumped back t o the double shell tanks (DSTs) and stored for further treatment after being concentrated t o target levels. The process condensate ( P C ) is primarily water t h a t contains trace amounts of organic material and a greatly reduced concentration of radionuclides. Currently, the PC i s stored i n the Liquid Effluent Retention Facility ( L E R F ) u n t i l i t can be further processed i n the Effluent Treatment Facility (ETF) once i t i s operational. The process exhaust or vessel vent stream i s filtered for fine particulate and discharged through a n exhaust stack. simplified schematic of the Evaporator. Evaporator i s contained i n the 242-A Evaporator Part B Dangerous Waste Permit App7ication (DOE-RL 1991a).

3.0 WASTE STREAM IDENTIFICATION


All of the waste accepted by the Evaporator comes from double-shell tanks (DSTs). The waste i n the DSTs is received from onsite generators, which characterize the waste before transfer t o the DSTs. Waste characterization is based on actual analytical knowledge and/or process know1 edge. Based on t h i s and other avai 1 ab1 e information, certain DSTs are selected as "candidates" for being processed i n the Evaporator. The contents of these candidate feed tanks are subjected t o closer scrutiny and evaluated aga ins t processing criteria before the f ina l t a n k selection is made. I n order t o meet processing cr i ter ia , the contents of several tanks may be blended together i n the Evaporator Feed Tank (TK-241-AW-102) prior t o actually being processed i n the Evaporator.

3.1 IDENTIFICATION OF WASTE

The waste processed i n the evaporator i s classified as a mixed waste because i t contains both radioactive and hazardous chemical components. H i stori cal analytical d a t a for the three dangerous waste streams (feed, slurry, and process condensate) are presented i n Chapter 3.0 of the 242-A Evaporator Part B Dangerous Waste Permit Application (DOE-RL 1991a). stream are classified as extremely hazardous waste as specified i n WAC 173-303-100 (5 ) . sl urry after bei ng processed i n the Evaporator. Because some radi onucl ides and dangerous waste constituents may carry over i n t o the process condensate. The PC remains classified as a dangerous waste per WAC 173-303-100. Table 3-1 l i s t s the waste codes which are applied t o the feed and slurry streams a t the 242-A Evaporator.

The candidate feed tanks, feed stream, and slurry

Most of the radionuclides and dangerous waste constituents remain i n the

Analysi s of u t i 1 i t y streams i ncl udi ng cool i ng water and steam condensate are conducted. These analyses are not discussed i n this plan because these streams are not considered dangerous wastes under WAC 173-303.

3.2 GENERAL CONSTITUENT DESCRIPTION

The waste sent t o the Evaporator contains water as a major constituent of the waste. The pH of the waste can be 12.5 or higher due t o the quant i ty of hydroxide used as corrosion protection for the DSTs. Qualitatively, the other major constituents o f the mixed waste are sodium salts of nitrate, n i t r i t e , fluoride, phosphate, carbonate, and sulfate. Additionally other salts including calcium, aluminum, and potassium sal ts may be present. Detectable levels of halogenated and non-

4



halogenated organic compounds may also be present. The mixed waste i n some t a n k s has detectable levels of heavy metals such as lead, chromium, and cadmium. The radionuclide content includes fission products such as the isotopes 'OSr and 137Cs and actinide series elements such as uranium and plutonium.

3.3 WASTE CHARACTERISTICS

Due t o the blending which occurs i n the Evaporator Feed T a n k , the composition of waste actually sent t o the Evaporator is more homogenized t h a n the waste i n the candidate feed tanks. Generally, this waste i s a stable aqueous l i q u i d w i t h a low organic content. The waste has been desi gnated as characteri s t i cal l y i gni tab1 e , corrosive, reactive, and TCLP toxic per WAC 173-303-090. I t has also been designated as a n extremely hazardous waste because i t meets the toxic, carcinogenic, and persistent cri teria described i n WAC 173-303-100. The waste has also been assigned the nonspecific waste codes FOOl t o F005 due t o the presence of spent ha1 ogenated and nonhal ogenated sol vents. The Evaporator may a1 so process waste from leachate systems t h a t has been assigned the nonspecific waste code F039.

The Evaporator separates the waste i n t o two streams (slurry and the process condensate) which are sent t o other treatment, storage, or disposal (TSD) units. Process knowledge and historical d a t a indicate t h a t the slurry stream exhibits the same dangerous waste properties as the waste feed, so the same dangerous waste codes are appl i cab1 e t o the slurry. The process condensate exhibits d i fferent dangerous waste characteristics because most of the nonvolatile toxic compounds have remained i n the slurry. The process condensate has s t i l l been assigned the nonspecific source codes FOOl t o F005 and F039 because i t has been derived from the treatment o f a l isted waste. The PC i s also designated s ta te characteristically toxic (WT02) due t o the potential ammonia concentration.

Table 3-1 contains a l i s t of the dangerous waste codes assigned t o the feed and slurry streams o f the 242-A Evaporator i n the Hanford F a c i l i t y Dangerous Waste Part A Permit App7ication (DOE/RL-88-21). Table 3-2 contains a l i s t i n g of the dangerous waste codes which have been assigned t o the process condensate i n the LERF portion of the Hanford F a c i l i t y Dangerous Waste Part A Permit Appl icat ion (DOEIRL-88-21). A detailed description of waste designation i s contained i n Chapter 3.0 of the Evaporator Part 5 permit app7ication (DOE-RL 1991a) .

The DST waste was designated ignitable due t o the presence of nitrates and n i t r i t es , which are classified as oxidizers i n 49 CFR 173. However the concentrations of these nitrogen compounds i n the waste are normally so dilute t h a t i g n i t a b i l i t y i s not an issue. DSTs which contain concentrated quantities of these materials, such as t a n k lOl-SY, will not be processed i n the Evaporator without an evaluation of the potential i g n i t a b i l i t y problem.

To confirm t h a t a waste wi l l n o t produce a n exothermic or spontaneous reaction t h a t would result i n a violent change, a differential scanning calorimetry (DSC) check is performed on samples from the candidate feed tanks. the waste is not reactive.

4.0 EVAPORATOR PROCESSING CRITERIA

Processing criteria have been established from regulatory requi rements, operating experience , process know1 edge, analyses, and cal cul a t i ons . Processing cri ter i a are maximum and/or minimum values of a waste analyte t h a t , i f exceeded, alert the operator t h a t the waste requires further attention before proceeding. Prior t o each evaporator campaign, candidate feed t a n k analyses i n conjunction w i t h processing criteria are used t o develop a control p l a n which is used t o ensure t h a t established limits will not be exceeded. The criteria selection process is discussed i n detail i n the 242-A Evaporator/LERF DQO Document (Von Bargen 1995). The reason for selecting a given analyte for inclusion i n this WAP as required by WAC 173-303, is indicated i n Sections 4 .1 and 4 . 2 of this p l a n .

Add i t iona l analyses of the Evaporator streams (feed, slurry, and PC) v i a process control sampling are conducted for the purpose of monitoring the evaporation process and ensuring t h a t a l l streams will meet a l l established operating cr i ter ia . This type of sampling i s considered outside the scope of this p l a n and i s addressed by the latest editions of the 242-A Evaporator Process Control P l a n (the p l a n for each campaign has a unique number beginning w i t h WHC-SD-WM-PCP-) , and the DST WAP (Mu1 key and Jones 1995).

4.1 CANDIDATE FEED TANK WASTE ACCEPTANCE AND PROCESS CRITERIA

Sections 4.1.1 through 4.1.4 discuss waste acceptance analysis i ssues and the assurances t h a t processing criteria will not be exceeded when waste from the candidate feed tanks is processed i n the Evaporator.

4.1.1 Exothermic R e a c t i o n s

To eval uate the probabi 1 i t y of an uncontrol 1 ed reaction, a di fferenti a1 scanning calorimeter (DSC) tes t is performed on a l l waste t o be processed i n the Evaporator. Waste exhibiting exotherms below 335 OF (1680C1, or w i t h an absolute value of the exotherm-to-endotherm ratio greater t h a n one, wi 11 not be processed i n the Evaporator w i t h o u t further technical evaluation.

4.1.2 Compati bi 1 i t y

A compatibility evaluation is performed on wastes from the candidate feed t a n k s i n order t o verify t h a t there will be no adverse affects due t o mixing the contents o f different waste t a n k s i n the 242-A Evaporator feed t a n k . The evaluation uses information gained from a mixing and compatibility study. As part of the mixing and compatibility study, samples of waste from the candidate feed tanks are taken t o the

12

2 4 2 - A EVAPORATOR WASTE ANALYSIS PLAN A p r i l 13, 1995


laboratory where they are combined, mixed, and then observed for any unusual changes i n color, temperature, clari ty, solids formation, or other visual characteristic. I f any changes are observed, further compati bi 1 i t y evaluations w i 11 be conducted or the wastes wi l l not be processed.

4.1.3 Organic Constituents

The levels of volatile organics i n the candidate feed tanks must be limited t o prevent organic vessel vent emissions from exceeding 3 lbs/hr and 3.1 tons/yr dur ing processing (40 CFR 265). To ensure t h a t these limits are not exceeded, equilibrium calculations were performed i n the 242-A Evaporator Part 5 Dangerous Waste Permit Appl icat ion (DOE/RL 1991a) t o determine limits for i n d i v i d u a l organic constituents. These l imits , shown i n Table 4 . 1 , include a modifier "R-l/R". which adjusts the limits based on the campaign's planned boil-off rate ( R i s the ratio of feed flow rate t o slurry flow rate) .

The organic limits i n the permit application were based on twelve months of continuous operation each year. These limits were adjusted t o six months continuous operation each year for this p lan . The six months operating i s a realist ic l imi t because the Evaporator must shut down during the year for maintenance outages, candidate feed t a n k analysis, and establ i shi ng transfer routes for staging the waste into the feed t a n k . Since the limits are based on a calendar year and they depend on operating time, the limits i n Table 4 . 1 may need t o be adjusted t o reflect actual operation. The t o t a l carbon (TC) minus the t o t a l inorganic carbon (TIC) is used as a screening tool to account for a l l organic species (Von Bargen 1995). TIC l imit i s exceeded, a more detailed evaluation will be conducted t o determine organic emissions out of the vessel vent. This l imit of 87 mg/L i s based on the assumption t h a t a l l organic species are volatile and are calculated as acetone (as i f a l l organic species were acetone) due t o i t s relatively low carbon percentage (Von Bargen 1995).

I f the TC-

In addition t o the organics w i t h limits shown i n Table 4 .1 , analyses for 2-hexanone, 2-pentanone, methyl isobutyl ketone, and tetrahydrofuran w i 11 be conducted t o ensure they are not routinely present i n the waste. In the future, characterizations of candidate feed t a n k waste ( i f these compounds are regularly seen) feed limits will be added for these organics as well.

The level of volatile organics i n the feed must be limited to ensure PC is compatible w i t h the LERF l iner. The HDPE liner used a t the LERF is exposed t o PC t h a t may contain trace quantities of chemicals, which i n turn may cause degradation of the liner material. Based on the liner manufacturer's d a t a , the concentration limits i n Table 4 .2 are imposed on those classes of constituents t h a t could potentially degrade the liner (Von Bargen 1995). To ensure t h a t these limits are

13

242-A EVAPORATOR WASTE ANALYSIS PLAN April 13. 1995


not exceeded i n the process condensate, the concentration limits are applied t o the candidate feed tanks as well and modified by " R - l / R , " as appropriate.

4.1.4 Ammonia

The candidate feed t a n k s must be sampled for ammonia so t h a t processing can be adjusted t o ensure the process condensate does n o t exceed 1 w t % ammonia, which i s the l imi t for Washington State extremely hazardous waste as indicated i n WAC 173- 303-100. The 1 w t % limit equates t o a concentration o f O.58M-ammonia i n the process condensate. This assumes a typical 50% waste volume reduction per pass ( R equals 2) through the Evaporator and conservatively assumes a1 1 the ammoni a transfers w i t h the process condensate, processing adjustments such as candidate feed t a n k blending are made t o ensure the ammonia concentration i n the feed stream remains below 0.29M- (5 ,000 mg/L).

5.0 CANDIDATE FEED TANK SAMPLING AND ANALYSIS

This section di scusses parameters associated w i t h the candidate feed tanks. The parameters include t a n k selection, sampling frequency, and selection of analytes. Due t o the highly radioactive nature of the samples, i t i s anticipated t h a t a l l analyses will be conducted a t one of the laboratories on the Hanford Site because they are equipped t o handle such samples. the analysis needed and the a v a i l a b i l i t y and capability of the laboratories a t the time of sampling.

Laboratory selection will be dependent on

I t is recognized t h a t analytical d a t a from candidate feed tanks may be available from other programs. Data from other programs which meets the cri teria contained i,n the 242-A Evaporator DQO (Von Bargen 95) can be substituted for the sampling and analysis requi red by this document.

5 . 1 SELECTION OF CANDIDATE FEED TANKS

The Evaporator feed stream originates from the DSTs. For each campaign of the 242-A Evaporator, DSTs will be selected based on process knowledge of waste characteri s t i cs (components) w i t h respect t o waste acceptabi 1 i t y cri teria provided i n Section 4 . 0 of this p l a n . I f the waste i s suitable for evaporation, i t wi l l be transferred t o the evaporator feed t a n k , TK-241-AW-102.

5 . 2 SAMPLE COLLECTION

The number of lateral sampling locations i n candidate feed tanks i s limited by the availability o f t a n k risers providing access i n t o the t a n k . Generally, only a few risers i n each t a n k are actually available for sampling because some of the risers are dedicated t o instrumentation or other uses. Sampling w i t h i n a vertical column is generally limited only by the depth of waste i n the t a n k . The number of available sample locations, information on the proximity of expected t a n k analyte concentration t o a decision point or target threshold, and information from previous Evaporator runs will be used t o statist ically determine the number of samples necessary t o verify the composition of the t a n k . The statist ical analysis includes the generation of power curves as indicated i n the 242-A Evaporator/LERF DQO Document (Von Bargen 1995). The number of samples required are based on the criteria action level (target threshold), estimated or known concentrations, and the required confidence levels (which are based on the consequences of a wrong decision). (cri teri a 1 then more samples are requi red t o minimize sampl i ng anomal i es .

5-1 i l lustrates the decision logic p a t h which can be used t o determine the number of samples needed for a given t a n k . Generally three t o five samples will be taken from each candidate feed t a n k .

Samples will be obtained by using a grab sampling (e.g. "bottle on a string method") method approved for use on the Hanford Site. Normally only one set of samples will be needed for each candidate feed t a n k . Additional samples may be taken i f needed t o confirm t h a t processing criteria will be met. Table 5.1 should be used when determining the specific sampling locations:

Table 5 - 1 Sample Point Selection

I Number o f Samples Location o f Sample Points

Two Samples One sample taken from the upper h a l f of the'waste from one riser and the other sample taken from the lower h a l f of the waste from another riser.

I

Three Samples Two Samples taken from one riser (one from the t o p h a l f and the other from the bottom half of the waste) and one sample from another riser (determined by random number generator).

I

Four Samples Two samples taken from each of two separate risers. One sample is t o be taken from the t o p h a l f of the waste and one from the bottom h a l f of the waste from each of the selected risers.

I

Five Samples Same as for four samples except one sample from either the top or bottom ha l f of the t a n k will be taken from a t h i r d riser

I

Riser selection wi l l be made by numbering the available risers which are a t least 15 feet from each other and using a random number generator t o select which risers will be used. Sample depth will be determined by d i v i d i n g the t a n k level into one foot

increments and then by using a random number generator t o determine a depth which meets the cri teria given i n Table 5-1.

Presence of a separable organic layer i s determined by collection of one a d d i t i o n a l surface grab sample from each of the candidate feed t anks . The samples are analyzed for TOC as well as a visual determination and compared t o the TOC for the supernate layer i n the tanks t o determine i f a separable organic layer is present. Analytical d a t a taken for other purposes (such as from a compatibility study) can be used for the determination of the presence of a separable organic layer i f i t is available and meets the evaporator program requirements.

The requirements contained i n the latest editions of the 242-A Evaporator/LERF DQO (Von Bargen 1995) and the 242-A Evaporator Qua l i ty Assurance Project P l a n (Basra 1995) regarding QA/QC requirements, sample size, and holding times must be met. A chain of custody must also be completed for all samples required to be taken by this p l a n . The chain of custody must include a discrete sample number, date and time sample was taken, shipment number, and signature.

5.3 ANALYTE SELECTION AND RATIONALE

The 242-A Evaporator/LERF DQO Document (Von Bargen 1995) examined the d a t a needs for sampling the candidate feed tanks and determined t h a t the analyses i n Table 5-2 should be conducted i n order t o satisfy WAC 173-303-300 ( b ) requirements. The 242-A Evaporator/LERF DQO Document (Von Bargen 1995) contains additional information on how and why these analytes were selected.

5.4 ANALYTICAL MEMODS AND QA/QC

Performance based specifications rather t h a n procedure based specifications were used for determining appropriate analytical methods due to problems associated w i t h analysis of waste w i t h high radioactivity and the sample matrix. This allows adjustments for Hanford site-specific issues while ensuring acceptable d a t a q u a l i t y . The tes t methods which must be followed are included i n Table 5-2. The analyses will i n some cases deviate from SW-846 specifications for holding times, sample preservation, and other specific analytical procedures. discussed i n Analyt ical Methods fo r Mixed Waste Analysis a t the Hanford S i t e (DOE/RL 1994). All analytical and sampling methods conducted as part of this p l a n must meet the d a t a q u a l i t y requirements contained i n the latest editions of the 242-A Evaporator/LERF DQO (Von Bargen 1995) and the 242-A Evaporator Quality Assurance Project Plan (Basra 1995).
