Docket Mos. 50-460 and 50-513 11.0 Radioactive Waste Management 11.1 _ Summary Description The radioactive waste systems will consist of the liquid waste systen, the gaseous vaste system, and the solid waste system. The liquid ~
waste system will process vaste liquid streams such as equipment
~
drair.s, coolant leakage, domineralizer regenerant liquids, decon-tamination and laboratory waste liquids, and laundry and shower waste water. The treated liquid waste will be recycled for reuse if the plant water balance requires makeup and if the water quality is adequate. The liquid waste systems will utilize evaporation, reverse osmosis, demineralization, and filtration for removal of
, radioactive material, chemical impurities, ar.d particulates.
Gaseous vastes will be generated during the operation of the plant from degassing primary coolant, from vents for equipment hcndling radioactive materials, and due to leakage from systems and components.
containing radioactive material. The gaseous vaste system will treat gaseous streams for radioactive material removal by filtration, adsorption, and holdup for radioactivity decay. The treated gas streams will be released to the environment.
Solid wastes will be generated during plant operation. The wastes will consist of waste materials such as contaminated clothing, reverse osmosis concentrates, boron recovery evaporator bottoms, demineralizer e
o
e-
- 2- .
resins and discarded radioactive components and tools. Treatment a
will consist of solidification, packaging, and shipping to a licensed burial site. Each unit will have separate liquid, gaseous and solid radioactive waste management systems.
In Amendment 11, the applicant has agreed to incorporate the guide-lines of ETSB Position No. 1 for the liquid, gaseous, and solid radwaste systems. Our' evaluation is based on this commitment.
- 1 In the Draft Environmental Statement (DES) for Washington Nuclear Projects Units 1 and 4, we performed an evaluation to determine the quantities of radioactive materials that will be released in
.the liquid and gaseous plant effluents, and that will be shipped 1
offsite as solid wastes for burial. In that evaluation we considered waste flows, waste activities, and equipment operating performance that are consistent with normal plant operation, including anticipated operational occurrences, over the life of
.the plant. ,
t The parameters used in the DES evaluation, along with their bases, l
are given in Appendix B to WASH-1258. Modified versions of the ORIGEN and STEFFEG Codes, which were the liquid and gaseous cal-
!- culational models, are given in Appendix C to WASH-1258. Our evaluation of the system decontamination factors, along with a listing of plant dependent parameters, is given in Table 3.5.1 of the DES.

11.2 Liquid Raduaste Treatment System -
11.2.1 Description and Evaluation In our evaluation of the liquid radwaste system we have considered:
- 1) the system's capability to reduce radioactive releases to "as low as practicable" levels based on expected radwaste inputs
-over the life o'f the plant; 2) the system's capability to maintain releases below the limits in 10 CFR Part 20 Appendix B, Table 2, Column II,during periods of fission product Icakage at design levels from the' fuel; 3) the system's capab11Iity to meet the processing demands of the station during anticipated operational occurrences in-cluding back to back refueling; 4) the quality group classification and seismic category applied to the system designt and 5) the design features incorporated to preclude uncontrolled releases of i
radioactive materials due to tank overflows. The process and s
effluent monitoring design capabilitics are considered in Section 11.5.
The Boron Recycle System (BRS) will process shim bleed and equipment drain waste, collected inside the reactor containtaent, as well as process equipment drain wastes and tank overflows vastes, from components outside reactor containment. BRS wastes will be processed by means of evaporation and demineralization. Each unit will be is provided with two BRS evaporators, with design capacities of 22,600 gpd each. We calculate the average expected vaste flows to the BRS to be 29,000 gpd/ reactor. The difference between the
i expected flows and the total design capacity of 45,200 gpd Will provide adequate reserve for processing surge flows.
Liquid radwastes from the general services building drcins will be collected in sumps and transferred to the liquid radwaste receiver tanks. The contents of the tanks will be processed through a reverse osmosis module and two demineralizers in series on a -
l batch basis and pumped directly to one of the liquid waste test i
tanks for final testing prior to recycle for inplant use or release to the cooling tower blowdown. Tritiated liquid radwastes and aerated liquid radwastes will be segregated by separate sucp and transfer systems; however, both types of liquid raduaste wi11 he processed through the same reverse osmosis modules and dcmineralizer trains. Tritiated wastes will be recycled to the reactor coolant
\ distillate storage tank while aerated wastes will be recycled to
\
the reactor coolant distillate storage tank, condensate makeup tank,'
or the reprocessed water system, depending on the tritium content.
The' design capacitics of the two reverse osmosis modules and four domineralizers are 10 gpm each. Two parallel trains of one reverse i .
i osmosis module and two series-connected domineralizers will be provided.
Interconnections will be provided for operational ficxibility. Con-tents of collection tanks will be pumped batchwise to process feed tanks where the p11 will be adjusted on a batch basis for optimum reverse osmosis membrane efficiency. We estimate the average input to the liquid radwaste system to be 1800 gpd per reactor. Since the system can handle approximately 23,800 gpd '
per reactor based on 1
the capacity of tuo parallel reverse osmosis modules, we find the system adequate for meeting the demands during normal operation, including anticipated operational occurrences.
Turbine building sump wastes will normally be released without treatment after monitoring for radioactivity.
, once through steam generators will be used and therefore no steam generator blowdown treatment system will be provided.
i '
j Our evaluation of the liquid radwaste treatment systems for normal l operation is given in the Draft Environmental Statement (DES) for Washington Nuclear Project, Units 1 and 4. As indicated in the DES, ne ha,0 determined, that the proposed liquid radwaste treatment systems
__ j will be capable of reducing the release of radioactive materials in liquid effluents to approximately 0.1 Ci/yr/ reactor, excluding
\
tritium and dissolved gaces. An isotopic listing of our calculated liquid source term is given in Tabic 3.5.2 of the DES. Based on that evalcation, we have found that the release of radioactive materials in liquid effluents will not result in whole body or I
critical organ doses in excess of 5 mrem /yr at or beyond the site j
boundary, and radioactive materials released in liquid effluents, exclusive of tritium and dissolved gases, will not exceed 5 Ci/yr/
g reactor. We have reviewed the effects of reactor operation with 1% of the operating fission product inventory in the core being I

released to the primary coolan,t. We have determined that under theseconditions,theconce$trationsofradioactivematerialsin 11guld effluents will be a small fraction of the limits in 10 CFR Part 20, Table 2, Column II.
The liquid radwaste system components will be designed to Quality Group D (Augmented) and non-seismic Category I classification, and will be located in a structure designed to seismic Category I requirements, consistent with our guidelines. the quality group designations of the equipment are listed in Table 11.2.1.
The system will be designed to preclude the uncontrolled release of radioactive materials due to overflows from indoor and outdoor tanks by providing level instrumentation which will alarm in the control room, and by means of curbs and seismic Category I dikes to collect spillage and retain it for processing. We consider these provisions to be capable of preventing the uncontrolled release of radioactive materials to the environment. We find the applicant's .
proposed system design to be acceptable.
11.2.2 Findings The liquid radwaste system includes the equipment and instru=entation to control the release of radioactive materials in liquid effluents.
The scope of our review included the system's capability to reduce releases of radioactive materials in liquid effluents to "as low as i
7
f practicable" levels in accordance with'10 CFR Parts 20 and 50.36a, considering normal operation and anticipated operational occurrences, and the design provisions incorporated to preclude uncontrolled releases of radioactive materials in liquids due to leakage or overflows in accordance with General Design Criterion 60.
The review has included an evaluation of effluent releases based
. the proposed treatment processes.
Included in the review were piping and instrumentation diagrams, s,chematic diagrams, and descriptive information from the PSAR.
The basis for acceptance in our review has been conformance of the applicant 's design, design criteria, and design bases for the liquid radwaste system to the Commission's Regulations and to ..
applicable Regulatory Guides, as referenced above, as well as staff technical positions and industry standards.
Based on the foregoing evaluation, we conclude that the proposed liquid radwaste system is acceptable.
11.3 Caseous Radcaste Treatment System 11.3.1 Description and Evaluation In our evaluation of the gaseous radwaste treatment system we have considered:
- 1) the system's capability to reduce radioactive releases to "as low as practicable" levels based on expected gaseous waste inputs and radioactive leakage rates over the life of the plant, 9
e N. 3 +
b o.
'g s
- 2) the system's capability to maintain releases below the limits in 10 CFR Part '20, Appendix D, Table 2, Column I during periods of fission product leakage at design levels from the fuel, 3) the system's capabilities to meet the processing demands of the station during anticipated operational occurrences, and 4) the
-quality group classification and seismic category applied to the system design. The process and effluent monitoring design capabilities are considered in Section 11.5.
In our evaluation we have considered the following systems:
(1) Radioactive Caseous Waste System (2) Main Condenser Offgas System (3) Ventilation Exhaust Systems 11.3.1.1 Radioactive Cascous Uaste System g
The Radioactive Gaseous Waste System (RCUS) will process gases (1) stripped from the primary coolant in the CVCS and BRS, (2) from the reactor coolant drain tank cover gas and miscellaneous tank cover gas system's and (3) from the FailedFuel Detection System (an 3
estimated 500 ft /yr of potentially contaminated nitrogen). All of ti.a listed sources enter the RGWS header upstream of the comprecsor.
The gases, consisting mostly of nitrogen, hydrogen, and small amounts of radioactive gases will be mixed with the 40 scfm recirculating nitrogen stream to keep the composition below the flammable limits.
The gases will be compressed by one of two 40 scfm capacity compressors I-
II 4
-9_
and passed through one of tuo 1.4 scfm' capacity recombiners, where the hydrogen is recombined with oxygen and removed as water from the system. The compressed gases will be stored in four gas decay tanks (600 cu.ft. each) at 75 psig. One tank will be filling while being used in the recirculating stream, while one will be venting to the atmosphere, one tank will be holding up gases, and the fourth tank vill be kept in reserve to accomodate unexpected operational occurrences. The gases uill held for approximately 90daysbeforetheyarereleasedtothicatmosphere,thusonly small amounts (approximately 1,000 Ci/yr/ reactor) of krypton-85 and
- kenon-133 will be discharged to the environment.
11.3.1.2 !!a2.c :ondenser Offgan Systen' Radioactive gases from the main condenser vacuum pumps will
\
normally be released without treatment. If concentrations of particulates or iodine exceed predetermined levels, a standby system consisting of liEPA filters' and charcoal adcorbers can be placed in operati,on to reduce releases. ,
11.3.1.3 ventilation F.xhaust Systems Ventilation exhausts from the primary auxiliary area of the general services building, from the safeguards building, and from the containment building purge system will be processed through HEPA filters and charcoal adsorbers prior to release. In addition, the D
I.
4-containment building atmosphere will be recirculated through HEPA filters and charcoal adosrbers prior to purging. The recirculation system has a capacity of 30,000 cim, which is sufficient to reduce the iodine-131 concentration by a factor of 77 in 16 hours1.851852e-4 days <br />0.00444 hours <br />2.645503e-5 weeks <br />6.088e-6 months <br /> of operation. ,
Ventilation exhausts from the radwaste processing area of the general services building will be passed through HEPA filters prior to release. Ventilation exhausts from the fuel handling area of the general services building will normally be released without treatment but can be exhausted through HEPA filters and charcoal adosrbers when effluent concentrations exceed a predetermined icvel.
.The. turbine bui1 ding ventilation exhausts will be released without treatment. -
- s. The plant ventilation systems will be designed to induce air flows from potentially less radioactivsly contaminated arcas to areas hav!ng a greater potential for radioactive contamination. Potentially contaminated building areas will be maintained at a slightly negative pressure with respect to the exterior pressure to procote collection of radioactive materials by the ventilation system and allow dispersion through roof and plant vent exhausts while reducing exfiltration. The ventilation system will have adequate capacity to limit radioactive material concentrations in areas within the plant that are accessible during operatica to below the limits in 10 CFR Part 20.
r Based on the proposed equipment, capacities of the components, and estimated flow quantitics, we consider the gaseous radwaste treatment system capacity adequate for normal operation and anticipated operational occurrences.
In the DES, we have determined that the proposed gaseous radwaste treatment systems and plant ventilation systems will be capable' of reducing the release of radioactive naterials in gaseous effluents to approximately 2,000 C1/yr/ reactor o.f noble gases and 0.032 Ci/yr/ reactor of iodine-131. An isotopic listing of our calculated gaseous source term is given in Table 3.5.3 of the DES. Based on that evaluation, the release of radioactive naterials in gaseous effluents will not result in an annual air dose, at or beyond the cite boundary, in excess of 10 mrad for gamma radiation and 20 mrad for beta radiation, the annual thyroid dose to an individual will be less than 15 mrem considering the location of the nearest cow, 4.3 miles SE of the site and the annual quantity of iodine-131 released will not exceed 1 Ci for each reactor at the site.
Design Features The RGUS will be located in the radwaste arca of the General Services Building, which is a seismic Category I structure. The gas decay tanks will be designed to Quality Group C and neismic-Category I classification up to an including the second isolation valve. The compressors, recombiners and other system components will be designed to Quality Croup D (Augnented) and non-seismic Category I 9
e
f classification, consistent with our guidelines. The quality group and seismic-category to which the equipment will be designed are listed in Table 11.3.1.
Most of the gas entering the RGUS during normal operations vill be from the CVCS gas stripper, .BRS evaporator, and cover gas displaced from the BRS holdup tanks containing hydrogen. To prevent .
oxygen inicakage into the system the vent header is designed to operate at a slightly positive pressure'. The contents of the gas decay tanks uill be continuously monitored for the presence of oxygen and hydrogen. When the oxygen content of the system exceeds 2%
the system vill be automatically isolated and an alarm in the control room will be activated. In this manner, the potential for explosive
, hydrogen / oxygen mixtures will be mitigated.
\
We find the system quality group and seismic design criteria along with the design provisions incorporated for the prevention of hydrogen explosions to be adequate.
11.3.2 Caseous Radwaste System Evaluation Findings The gaseous radwaste system includes the equipment and instrumentation to control the release of radioactive materials in gaseous effluents.
The scope of our revicu included the system's capability to reduce releases of radioactive materials in gaseous effluents to "as low as practicable" levels in accordance with 10 CFR Parts 20 and 50.36a considering normal operation and anticipated operationni occurrences, the quality group and seismic design criteria and the design provisions 9
p incorporated to reduce the potential for hydrogen explosions. The review has included an evaluation of effluent releares based on the proposed treatment processes and considering pathways due to
. process vents and leakage affecting building ventilation systems.

- 1 Based on the foregoing evaluation' we conclude that the proposed solid radwaste system is acceptable.
11.5 Process and Effluent Radiological Monitoring 11.5.1 System Evaluation and Description _
In our evaluation of the process and effluent monitoring system we have considered the system's capability 1) to monitor all normal and potential pathways for release of radioactive materials to the environment, 2) to control the release of radioactive materials to the environment, 3) to monitor the performance of process equipment and detect radioactive material leakage between systems, 4) to periodically take samples for analyses for systems which are not amenable to continuous monitoring or where detailed isotopic analysis are required.
17 '
We have. reviewed the locations,and types of effluent.and process o
monitoring provided. Based on the plant design and the continuous monitoring locations of gaseous and liquid effluents and sampling locations, we have concluded that all normal and potential release pathways will be monitored. ~
The design includes provisions for automatically terminating effluent releases in the event radiation levels in discharge lines er.ceed a predetermined level. Sampling and monitor 1ug provisions will be provided for detecting radioactive material leakage to normally uncontaminated systems and for monitoring plant processes which affect radioactivity releases.
11.5.2 Process and Effluent Radiological Monitoring Evaluation Findings.
The provisions for process and effluent radiological monitoring include the instrumentation and controls for monitoring and controlling the releases of radioactive materials in plant effluents and monitoring the level of radioactivity in process. streams. The scope of our review included the provisions for monitoring and controlling the release of radioactive materials in plant effluents in accordance with General Design Criteria 69 and 64 and Regulatory Guide 1.21, and for monitoring radioactivity Icycis within the plant in process streams in accordance with General Design Criterion 13.

e
. _ 18 ,' .
Regulations as set forth in the General Design Criteria and to applicable Regulatory Guides, as referenced above, as well as o t staff technical positions and industry standards.
Based on the foregoing evaluation, we conclude that the proposed provisions for monitoring process and effluent streams meet the requirements of General Design Criteria 13, 60 and 64 and the guidelines of Regulatory Guide 1.21 and ther fore, are acceptable.
- 7 15.24 Pontulated Radioactive Releases Due to Linuid Tank Failurcs We have evaluated the consequences of component failures which will result in contaminated liquid releases to the environs for components i
containing liquid radioact'ive materials lccated cutside reactor containment. The scope of our review included the calculation of radionuclide inventories in ctation components at design basis fission product levels, the mitigating effects of the plant design, and the effect of site geology and hydrology.
The radwaste tank that will contain the higheat total activity is the Tritiated Waste Collection Tank. This tank will have a volume of 12,000 gal. and is assumed to be 80% full with n liquid activity ,
concentration of approximately 10 uCi/ml (based on a 1% operating power fission product release to the primary coolant).
In our evaluation ue assumed the flow of ground uater will move in the direction of the Columbia River. The water supply for the city of i
Richland. Washington is taken from the Columbia River, at a point approximately 12 miles downstream from the plant. Based on the
.. description of the site hydrology in the PSAR, we evaluated the liquid cransit time for radwaste leakage to the Columbia' River to be 6.2 3 cars. Our evaluation assumes a ground water. dilution factor of 64 and neglects decay during transit. Upon entering the river, concentrations would be diluted by mixing uith a minimum stream flow of 36,00C cfs. Based on our evaluation, we conclude that a rupture-of the tritiated waste collection tank will give a concentration acLthe intake of less than the limits of 10 CFR Part 20, Appendix D,

The scope of our review included the-calcularien of radionuclide inventories in station components at design basis fission product icvels, the mitigating effects of the plant design, and the effect of site geology and hydrology. Radionuclide concentrations were calculated at the nearest potabic water supply.
The basis for acceptance in our review has been that the postulated failures should not result in radionuclide concentrations in excess of 10 CFR Part 20 limits at the water sources considered above.
