WNP-2 RADIOACTIVEEFFLUENT RELEASE REPORT JANUARY THROUGH DECEMBER 1997 WASHINGTON PUBLIC POWER SUPPLY SYSTEM LICENSE NO. NPF-21 9803030420 980223 PDR ADQCK 05000397 R PDR

i 1.0 Introduction This report is submitted in compliance with 10CFR50.36a(a)(2) and Technical Specification 5.6.3. It includes a summary of the quantities of radioactive liquid and gaseous effluents and solid radwaste released from WNP-2 during the previous twelve months of operation. Effluent data is summarized on a quarterly basis.

2.0 Liquid Effluents The radwaste liquid effluents were released in "batch mode" during the reporting period.

Table 2-0 summarizes the number and duration of batch releases, dilution flow and calculated maximum individual doses. The liquid batch releases were recirculated before sampling. A representative sample was obtained and analyzed for each batch release. A composite of the batch samples for each month was analyzed for tritium, and a composite sample for each quarter in which liquids were discharged was analyzed for strontium 89, strontium 90, and iron 55. 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 average flow rate of the Columbia River during January through December 1997 was 1.65E+05 cubic feet per second.

The percentage 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 the former 10CFR20, Appendix B, Table 2, Column 2.

Doses were calculated using the LADTAP II computer code, NUREG/CR-4013.

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 95 percent confidence level.

There were no liquid effluent monitors which were out of service for more than 30 days.

There were no abnormal releases.

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 percentage of ODCM Requirement For Operability limit, gross alpha radioactivity and the estimated total error associated with the measurements of radioactivity in the gaseous effluents.

Radioactivity measurements for gaseous effluent releases are performed for fission and activation gases by collecting the samples in a marinelli beaker and analyzing them using gamma spectroscopy. Tritium is analyzed by collecting the sample on a desiccant, distillation, and liquid scintillation counting. Particulates and iodines are sampled using particulate filters'and charcoal cartridges. Both are analyzed using gamma spectroscopy.

E bar was 4.30E-02 meV per disintegration.

Noble gas activities are commonly below detection limits in the building effluent ducts.

Where possible, noble gas concentrations in the effluent have been calculated from plant process data. Reactor building noble gas concentrations were calculated from offgas post treatment data.

Calculations were performed for releases using the NRC GASPAR II computer program and parameters as outlined in the ODCM. Quarterly doses to a member of the public were determined at the locations identified in the Annual Land Use Census and at the site boundary.

Table 3-0 summarizes the results of these calculations.

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 activity and sample volumes. The estimated error was determined to be 36 percent at the 95 percent confidence level.

The percent of ODCM limit for fission and activation gases (air dose) was determined for locations identified in the annual land use census, and was based on quarterly limits of ten (10) millirads for beta and five (5) millirads for gamma. These locations were used to determine the most restrictive value to be used in Table 3-4 for each quarter.

The ODCM limits are listed in Table 3-0.

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 near the laundry facility. The radiochemical hood within the backup chemistry lab contains HEPA filters and is monitored for radioactive releases when in operation. Gamma spectrometry indicated no radioactive materials present other than that attributable to natural background.

There were no abnormal releases of gaseous effluent during this reporting period.

The Radwaste building Intermediate Range noble gas monitor was out of service for 31 days between March 18 and April 18, 1997. The reason for the extended outage was that the calibration procedure contained inadequate guidance for correcting a decrease in monitor efficiency. Additional guidance for correcting this type of failure has been added to the calibration procedure for this and the one other similar monitor. This should prevent recurrence of this event.

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 instruments at the 33 ft and 245 ft levels. The meteorological data is a composite file from the automated data recovery systems for the calendar year 1997. Data is archived on Supply System Local Area Network.

Precipitation was slightly above normal in 1997. Total precipitation measured at the Hanford Meteorology Station was 6.39 inches, which is 102% of the normal 6.26 inches. Snowfall for January through March of the year was 6 inches, 96% of the normal 6.2 inches. The total snowfall for the November-December period was 24% of the normal 7.5 inches at 1.8 inches, Calendar year 1997 was warmer than normal, averaging 54.8'F or 1.3'bove normal. The occurrence of fog and haze and blowing dust in 1997 was similar to that observed in previous years. In summary, the dispersive environment for WNP-2 for 1997 was near normal.

Joint data recovery for 1997 was 92.2%. Scheduled power outages at WNP-2 coincided with the outages of the data recovery system. Lightning strikes and thunderstorms were of minor concern and had no significant effect on meteorological tower operations Tables 5-1 through 5-8 list the joint frequency distributions at the 33 ft and 245 ft levels by quarter for 1997. Table 5-9 and 5-10 list the annual joint frequency distributions for those levels for 1997. The NRC stability classes A through 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 1997 as the releases were random in time.

Calibrations performed in 1997 produced no values exceeding WNP-2 FSAR meteorological equipment tolerances and required no corrections be applied to the raw data. Data below 0.07 MPH has been determined to result from system malfunction and is not included in the results.

C 6.0 DOSE ASSESSMENT IMPACT ON MAN Liquid Effluents - The doses to the maximum individual from WNP-2 liquid effluents were calculated using the NRC LADTAP II computer code and 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 quarter are listed in Table 6-3. Table 6-4 provides annual doses to the average individual and 50-mile population doses from liquid effluents. All doses were calculated using the NRC LADTAP II computer code.

Gaseous Effluents - The NRC GASPAR II computer code was used to calculate doses at and beyond the site boundary. Table 6-5 lists the annual 50-mile dose using values obtained from the ALARAannual integrated population dose summary (person-rem).

Table 6-5 also provides the annual individual doses associated with each pathway. These values were obtained by dividing the ALARAintegrated dose (person-rem) by the 50-mile population (252,356 for year 1987) and converting to mrem. The GASPAR II runs use quarterly and annual meteorological data and site specific input parameters.

Exposure fo "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 3.81E-05 mrem. The annual thyroid dose was 3.91E-05 mrem and the maximum dose to any other organ was 4.67E-05 mrem. The air dose contribution was as follows; Beta air dose was 4.22E-03 mrad/yr and the Gamma air dose was 1.18E-02 mrad/yr.

The 1997 TLD summary showed no significant change from pre-operational values.

Based on one sigma error, the maximum direct radiation exposure to the public for calendar year 1997 was less than 10 mrem.

7.0 REVISIONS TO THE ODCM This section completes the requirement of Technical Specification 5.5.1. A complete, legible copy of the entire ODCM is included as an enclosure to the letter transmitting this Radioactive Effluent Release Report. ODCM's are sent only to the Nuclear Regulatory Commission (NRC).

8.0 REVISIONS TO THE PROCESS CONTROL PROGRAM (PCP)

There have been no major changes to the Process Control Program (PPM 1.12.2) during the reporting period, however, the procedure was revised effective 8/11/97. The description of dewatering system process controls was expanded to include the basis for concluding that adequate dryness is achieved and the role of the relative humidity endpoint was specified. Various references were added (or updated) including 10CFR61.56, ETSB 11-3, 10CFR20.2001 - 2006, Dewatering System Topical Report TP-02-P-A, IEB 79-19 and the BTP on Waste Form. Words specifying the controls applicable to solidification of oil in excess of 10% were replaced by prohibition of this activity since this waste form is no longer permitted at the US Ecology burial site. Volume based radioactive material characterization was described. The description of radioactive waste and radioactive material storage areas was expanded to reflect current conditions. Controls arising from the implementation of Industrial Packaging requirements were added and words specifying annual reverification of shipping computer codes were removed since code verification is required for each use and following updates. The required reporting of violations of Certificate of Compliance conditions for NRC approved shipping containers was specified.

Other changes included minor rewording or format changes.

9.0 NEW OR DELETED LOCATIONS FOR DOSE ASSESSMENTS AND/OR ENVIRONMENTALMONITORING LOCATIONS There were no new or deleted locations for dose assessments or environmental monitoring.

10.0 MAJOR CHANGES TO RADIOACTIVELIQUID, GASEOUS AND SOLID WASTE TREATMENT SYSTEMS No major changes were made to the radioactive waste systems (liquid, gaseous, or solid) during this reporting period.
