INTRODUCTION This report is submitted in compliance with 10CFR50.36a(a)(2) and Technical Specification 6.9.1.11. It includes a summary of the quantities of radioactive liquid and gaseous effluents and solid radwaste released from WNP-2 during the previous six months of operation. Effluent data is summarized on a quarterly basis.

2.0 LI UID EFFLUENTS The radwaste liquid effluents were released in "batch mode" during the reporting period. Seventy (70) liquid batch releases occurred during the third calendar quarter and 22 batch releases were performed during the fourth calendar quarter. The total time period for the batch releases was 179 hours0.00207 days 0.0497 hours 2.959656e-4 weeks 6.81095e-5 months , with the maximum, minimum and average time periods for a release being 2.7, 1.4, and 1.9 hours1.041667e-4 days 0.0025 hours 1.488095e-5 weeks 3.4245e-6 months , respectively. The volume of dilution water considered is assumed to be the total volume of recirculating cooling tower blowdown flow for the period. The average flow rate of the Columbia River during July through December 1992 was 8.9E+04 cubic feet per second.

Computer runs were performed to verify compliance with Offsite Dose Calculation Manual (ODCM) limits. The third quarter calculated dose for the maximum individual (adult age group) was 1.6E-03 mrem whole body and 2.7E-03 mrem for the maximum organ.

The fourth quarter calculated dose for the maximum individual (adult age group) was 4.1E-04 mrem whole body and 6.7E-04 mrem for the maximum organ.

The liquid batch releases were recirculated prior to sampling. A representative sample was obtained and analyzed for each batch release. A composite of the batch samples for each quarter was analyzed for strontium and iron. The methods used for measuring the total radioactivity were gamma spectroscopy, liquid scintillation and proportional counting. Table 2-1 provides a summation of all liquid releases during this reporting period.

The percent of MPC limit in Table 2-1 is based on the total of the MPC fractions using the nuclides in Table 2-2 and the concentrations listed in 10CFR20, Appendix B, Table 2, Column 2.

Estimated total errors are listed in Table 2-1, and are propagated from individual error estimates of sample activity, sample volume, tank volume, and tank homogeneity. The estimated total errors were calculated by obtaining the square root of the sum of the squares of the individual error contributions and multiplying by 1.96 for a 954 confidence level.

3.0 GASEOUS EFFLUENTS The gaseous radwaste effluents from WNP-2 were released from three (3) release points:

1. Main Plant Vent mixed mode release

2. Turbine Building ground level release

3. Radwaste Building ground level release The gaseous source terms from each release point are listed in Tables 3-1, 3-2, and 3-3. Table 3-4 provides a summation of the total activity released, the average release rate, the percent of ODCM Requirement For Operability limit, gross alpha radioactivity and the estimated total error associated with the measurements of radioactivity in the gaseous effluents. Included in Table 3-2 is the Tritium contribution by steam relief venting from the Turbine Building Auxiliary Boiler.

Radioactivity measurements for gaseous effluent releases are performed for fission and activation gases by collecting the samples on charcoal traps and analyzing them using gamma spectroscopy. Tritium is sampled by freeze trapping and analyzed by liquid scintillation counting. Particulates and iodines are sampled using particulate filters and charcoal cartridges. Both are analyzed using gamma spectroscopy.

Total error estimates are propagated from individual error estimates of sample volume, sample activity and effluent flow rate measurements. The overriding uncertainty in all cases is in the measurement of the effluent and sample volumes. The estimated error was determined to be 36~ at the 95% confidence level.

The percent of ODCM limit for fission and activation gases (air dose) was determined for locations 1 through 8 and was based on quarterly limits of ten (10) millirads for beta and five (5) millirads for gamma. Locations 1 through 8 were used to determine the most restrictive value to be used in Table 3-4, Section A.3.

The percent of ODCM limit calculations for iodines, particulates with half-lives greater than eight (8) days and tritium are based on the quarterly limit of 7.5 mrem to any organ. Locations 4 through 8 were used to determine the most restrictive value to be used in Table 3-4 for each quarter.

Calculations were performed for releases using the NRC GASPAR II computer program and parameters as outlined in the ODCM.

Quarterly doses were determined at the following locations:

In addition to the reactor facility, WNP-2 has a permanent laundry facility located approximately 0.75 miles from the reactor building. Its ventilation system contains HEPA filters on the discharge and is continuously monitored for particulates. Also, the backup chemistry laboratory within the Emergency Operations Facility (EOF) is located adjacent to the laundry facility. The hood within the backup chemistry lab contains HEPA filters and is monitored for radioactive releases when in

'adiochemical operation. Gamma spectrometry indicated no radioactive material present other than that attributable to natural background.

There were no abnormal releases of gaseous effluent during the third and fourth quarters of 1992."'here were two reportable occurrences for inclusion into this Radioactive Effluent Release Report.

1 ~ PER NUMBER 292-1019 was issued to identify a flow verification being greater than a four hour interval. ODCM Table 6.1.2.1-1, Radioactive Gaseous Effluent Monitoring Instrumentation, Instrument 4, Item e, Sampler Flow Rate Monitor refers to Compensatory Measure 113. Compensatory Measure 113 states,"With the number of Channels OPERABLE less than required by the Minimum Channels OPERABLE requirement, effluent releases via this pathway may continue for up to 30 days provided that the flow rate is estimated at least once per 4 hours4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months ". Contrary to this requirement, a flow verification was 2.5 hours5.787037e-5 days 0.00139 hours 8.267196e-6 weeks 1.9025e-6 months overdue.

The above mentioned occurrence had no adverse effect on plant emissions or the health and safety of the public or plant personnel.

2 ~ A ten millicurie Nickel-63 gas ionization source was inadvertently opened within a clean work area, the attendant Health Physics Technician smeared the source surface and found removable activity. PER 292-0254 was issued, the resolution was to modify the procedure so that the equipment requiring source disassembly will be moved to a designated radiologically controlled area prior to disassembly. The source was reassembled and was verified radiologically clean.

4.0 SOLID RADWASTE A total volume of 10670.9 ft3 (302.0 m~) of solid waste was transported in 42 shipments during the July through December 1992 reporting period. The reported volumes are the disposal volumes of the containers shipped for burial. The total activity of the waste shipped was 777 Ci; 725 Ci was contained in dewatered spent resins and 51.5 Ci was contained in DAW.

A. Dewatered S ent Resin Twenty five (25) shipments consisted of dewatered resins which accounted for 4028.2 ft'114.0 m') of the radioactive wastes shipped during the reporting period.

The burial containers were ES-190 and EL-142 liners provided by NUPAC Services, Inc. The total activity of the resins shipped during the reporting period was 725 Ci.

The principal nuclides and their percent contribution to the total activity are listed in Table 4-3. The solid wastes were shipped to the U S Ecology Hanford Burial Site using NUPAC 10-142, NUPAC 14-210 casks or Supply System flatbed trucks.

The counting error associated with the total activity has consistently been found to be less than 3.0% at one standard deviation for previous reporting periods. The statistical counting error is assumed to be 3.04 for the purpose of this error evaluation.

Other parameters considered in estimating the total error of the activity shipped included the error in measuring the absolute volume, the weight of the waste in the liners, the representativeness of the sample taken, the homogeneity of the nuclide distribution within a batch or liner and the geometry error in the gamma spectroscopy analysis. The gamma spectroscopy calibration error is approximately 5%. The best estimate of the total error in the activity of spent resin shipped is assumed to be approximately plus or minus 25%.

B. Dr Active Waste DAW A total of 6642.7 ft (188.0 m ) of DAW was shipped in Container Products Corporation B-25 boxes or NUPAC Services ES-190,ES-210 or EA-50 encapsulation liners. Three shipments (out of 17 total DAW shipments) were comprised of DAW which was volume reduced (supercompacted) and shipped by a vendor waste processor. The total activity of the DAW shipped was 51.5 Ci. The value of the activity shipped was determined by using computerized dose rate-to-Curie conversion factors. The conversion factors were based on a nuclide distribution taken from analysis of contamination representative of the major DAW production areas. This distribution is updated annually in conjunction with offsite (EFFLUENT.RPT/RADAR) analyses of hard-to-measure nuclides. Because of the high 19

activity in a single EA-50 (CRD filters) shipment, the normal DAW scaling factors were carefully scrutinized and adjusted to more accurately represent this waste stream for this shipment. Specifically Fe-55 and I-129 scaling factors were reduced (Fe-55/Co-60 from 7.12 to 1.12 and I-129/Cs-137 from 0.231 to 2.5E-07) based on comparisons with industry experience, past history, and more accurate sample results.

A meaningful counting error cannot be generated for DAW; however, the total error may be assumed to be less than or equal to 25%, since DAW would be subjected to similar error contributions as spent resin.

C. IRRADIATED COMPONENTS No Irradiated Components were shipped during the reporting period.

D. Other Waste No other waste was shipped during the reporting period.

4.1 Scalin Factor Methodolo Scaling factors are based on outside laboratory (SCIENTECH Inc.

formerly SAIC) analysis of hard-to-measure nuclides. Scaling factors are updated on an annual basis or when triggered by an order of magnitude change in corrosion to fission product ratios (Co-60/Cs-137) in the resin waste streams, as compared to the previous offsite analysis.

C-14 Ni-63 Fe-55 The ratio of each of these nuclides to Co-60 is determined after outside laboratory analysis of each waste stream. The resulting scaling factors are applied to the measured Co-60 concentration for a particular batch or container of radwaste to arrive at the C-14, Ni-63 and Fe-55 concentrations.

H-3 Tc-99 I-129 Sr-90 The ratio of each of these nuclides to Cs-137 is determined after outside laboratory analysis of each waste stream. The resulting scaling factors are applied to the measured Cs-137 concentration for a particular batch or container of radwaste to arrive at the H-3, Tc-99, I-129 and Sr-90 concentrations.

Transuranics The ratio of hard to measure TRU nuclides to Ce-144 is determined after outside laboratory analysis of each waste stream, as recommended by the AIF report, "Methodologies for Classification of Low Level Radioactive Waste for Nuclear Power Plants." These nuclides will be reported if Ce-144 is detected and TRU nuclides gPPLUENT.RPi'IRADI) 20

have been detected by outside laboratory analyses. TRU nuclides include Pu-239, Pu-238, Pu-241, Am-241, Cm-242 and Cm-244.

Outside laboratory LLDs must be at least 1 nCi/g for TRU, 35 nCi/g for PU-241 and 200 nCi/g for CM-242.

5.0 METEOROLOGY The meteorological data contained in Tables 5-1 through 5-10 were obtained from the WNP-2 meteorological tower located 2500 ft west of WNP-2. Data was recovered from 33 ft and 245 ft levels. The meteorological data is a composite file from both the manual and automated data recovery systems.

The year was wetter and the wind calmer than 1991. Precipitation was normal for 1992 with the occurrence of fog and haze and blowing dust much less than 1991. There were few arctic outbreaks of cold air with the one significant outbreak causing extensive soft fruit damage in early February 1992. The year 1992 was very rainy in the fall. Snowfall and rain were above normal.

In summary, the dispersive environment for WNP-2 for 1992 was normal.

The automated data recovery system continued to function at greater than 90% joint data recovery when power was provided by WNP-2 to the meteorological tower system. Power outages contributed to a total data recovery of less than 90% for 1992.

All significant outages coincided with scheduled and unscheduled outages at WNP-2. Lightening strikes and thunderstorms were of minor concern and had no significant, effect on meteorological tower operations. Backup alternative power is being added in 1993.

Tables 5-1 through 5-8 ft list the and the 245 ft levels joint frequency distributions at the 33 for 1992 by quarter with 5-9 and 5-10 listing the annual joint frequency distributions for 1992.

The NRC stability classes A-G and seven wind categories along with the 16 wind sectors were used to prepare each joint frequency table. The annual joint frequency tables should be used to evaluate any vents and purges during 1992 as the releases were random in time.

Calibrations performed in 1992 produced no values exceeding WNP-2 FSAR meteorological equipment tolerances. Therefore, there has been no corrections applied to the raw data.

C DOSE ASSESSMENT IMPACT ON MAN Liciuid Effluents The doses to the maximum individual from WNP-2 liquid effluents were calculated using the NRC LADTAP II computer code and the site specific input parameters.

Table 6-1 lists the doses to the maximum individual by calendar quarter along with the cumulative total body and maximum organ values. Doses by calendar quarters to the average exposed individual are listed in Table 6-2. The 50-mile population doses by calendar quarters are listed in Table 6-3. Table 6-4 provides annual dosages to the average individual and 50-mile population doses from liquid effluents. All doses were calculated using the NRC LADTAP II computer code.

An evaluation of the nearest orchard (approximately 3 miles downstream) using Columbia River water for its irrigation showed an adult total body dose value of 8.8E-05 mrem/yr, thyroid dose of 3.7E-06 mrem/yr and an organ dose value of 1.5E-04 mrem/yr.

The population doses at this location showed a total body value of 2.3E-04 person-rem, thyroid dose of 2.4E-07 person-rem and an organ value of 4.0E-04 person-rem.

Gaseous Effluents The NRC GASPAR II computer code was used to calculate doses at and beyond the site boundary. Table 6-5 furnishes a summary of quarterly air and organ doses. It also provides the annual total body and skin doses at and beyond the site boundary. Table 6-6 lists the annual 50-mile dose using values obtained from the ALARA annual integrated population dose summary (person-rem). Table 6-6 also provides the annual individual doses associated with each pathway. These values were obtained by dividing the ALARA integrated dose (person-rem) by the 50-mile population (252,356 for year 1987) and converting to mrem. The GASPAR II runs utilized quarterly and annual meteorological data and site specific input parameters.

6.1 Ex osure to "A Member of the Public" The WNP-2 Visitor Center was evaluated for assessment of radiation doses to "Members of the Public" due to their activities within the site boundary. The ODCM assumes an eight (8) hour per year occupancy by "A Member of the Public" at the Visitor Center. The dose assessment resulted in an annual calculated total body dose of 7.7E-04 mrem. The annual thyroid dose was 2.6E-03 mrem and the maximum dose to any other organ was 8.4E-04 mrem. The air dose contribution was as follows; Beta air dose was 2.3E-03 mrad and the Gamma air dose was 3.2E-03 mrad. The direct radiation contribution from TLD results calculated to an average of 1.7E-01 mrem per eight hour period.

(EPFLUENT.RPT/RAD1) 36

The annual assessment of radiation doses to the most likely exposed "Member of the Public" to show conformance with 40CFR Part 190 is assumed to be located in the Taylor Flats vicinity (6.4 miles in a Southeasterly direction). The NRC GASPAR computer code with annual source terms and XOQDOQ meteorological II data was used to obtain the dose assessment from gaseous effluents. It is assumed there is no dose contribution from liquid effluents at this location. The assessment of the maximum age group resulted in annual calculated total body dose of 2.8E-03 mrem. The annual thyroid dose was 2.9E-02 mrem and the maximum dose to any other organ was 3.8E-03 mrem. Exposure pathways were ground, meat, cow milk and inhalation. The air dose contribution was as follows; Beta air dose was 3.1E-03 mrad/yr and the Gamma air dose was 2.2E-03 mrad/yr.

An annual assessment of radiation doses to a "Member of the Public" was also made at a location in the vicinity of 4.5 miles east southeast. This location receives irrigation water from the Columbia River as mentioned in paragraph 6.0 above. The annual GASPAR II computer run resulted in a child total body dose of 6.7E-03 mrem. The annual child age group thyroid dose was 3.1E-02 mrem and the maximum dose to any other organ for the child age group was 8.6E-03 mrem. The annual Beta air dose was 4.8E-03 mrad and the Gamma air dose was 3.5E-03 mrad. The annual dose contribution due to liquid releases using vegetation from the irrigated food pathway and the child age group in the NRC LADTAP II computer run showed a total body dose of 1.4E-04 mrem. The annual thyroid dose was 1.1E-05 mrem and the maximum dose to any other organ was 3.4E-04 mrem.

The direct radiation contribution showed no'ignificant amount above normal background. The 1992 average TLD summary was 94 mrem per year.

For the NRC LADTAP II computer code which uses NUREG/CR-4013, "LADTAP II Technical Reference and User Guide," a dilution factor of 2,000 was an assumption due to the large flowrates in the Columbia River and assumed locations where fish may be caught. The use of the two different'dilutions, when applied to fish, would produce a factor of four (4) difference in the dose calculations. the dilution factor for LADTAP II input for aquatic food and the applicable factor for the near field dilution will both use 500.

The average discharge structure exit flow rate used will be two (2) cubic feet per second (cfs).

Therefore, the product of the average blowdown flow to the Columbia River, in cfs, and the applicable factor will be 1000 cfs, as per NUREG-0133.

The average discharge structure flowrate is the total blowdown flow for the periods of each semiannual report (i.e., each calendar quarter). The use of average flowrate was a concern to the NRC contractor, EGGG Idaho, Inc. NUREG-0133 specifies an aveiacVe blowdown flow can be used.

Electrofishing from four to three (one requires an intensive effort for anadromous and two resident). 4-5 days in the spring and in the fall. Because of the fluctuating water levels on the Snake River, in particular, it has become very difficult to obtain three resident species, in addition to the anadromous species. The effort expended to fulfillthe current requirements for frequency and number of samples is not justified by the results received. The fish sample results from the Snake River do not differ significantly from results from Columbia River fish. Cesium-137 is the only detectable radionuclide besides Potassium-40 (naturally occurring). The Cesium levels are comparable in both samples. This revision requires that if a significant increase occurs in the Columbia River results over the Snake River results, semiannual RFf/RADAR) sampling of both rivers would resume.
