..G 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 twelve 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. Twenty eight (28) liquid batch releases occurred during the first calendar quarter, 41 batch releases were performed during the second calendar quarter. There were 77 releases during the third calendar quarter.and 55 releases in the fourth calendar quarter. The total time period for the batch releases was 399 hours0.00462 days 0.111 hours 6.597222e-4 weeks 1.518195e-4 months , with the maximum, minimum and average time periods for a release being 5.33, 0.75, and 1.98 hours0.00113 days 0.0272 hours 1.62037e-4 weeks 3.7289e-5 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 January through December 1993 was 9.3E+04 cubic feet per second.

Computer runs were performed to verify compliance with Offsite Dose Calculation Manual (ODCM) limits. The first quarter calculated dose for the maximum individual (adult age group) was 9.3E-04 mrem whole body and 1.8E-03 to the maximum organ. The second quarter was 3.7E-02 whole body and 5.9E-02 to the maximum organ. The third quarter was 7.5E-02 mrem whole body and 1.2E-01 mrem to the maximum organ and the fourth quarter calculated dose was 6.7E-03 mrem whole body and 9.8E-03 mrem to 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 the former 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 95 percent confidence level.

EFPLUENT.RFf/RADI

A storm drain pond is located approximately 1500 feet northeast of the WNP-2. No routine releases of water containing radioactivity occurs to the storm drain pond. However, there are pathways which could contribute to tritium being found. Some normal sources, such as HVAC air wash units and steam releases which could condense on building roofs, could provide a source of tritium. A gradual buildup of other radioactive materials from extremely low levels of effluent activity is expected. The levels of tritium, and other radionuclides present and anticipated, are an insignificant contribution to site doses.

While the storm drain pond is not intended to be a radioactive liquid disposal area, some accumulation of radioactive materials will occur through these unpreventable paths. Although the storm drain pond is within the site boundary, there is a physical barrier (fence) to restrict unauthorized entry. There are also administrative controls to prevent intentional release of radioactive materials to this pond. Since there is no occupancy of the storm drain pond'area, and no consumption of the water, there is no actual dose from the release of the described radioactivity to the pond. Even under worst case assumptions, the tritium produced doses were calculated to be less than 0.02 millirem per year.

This storm drain pond is a sample station within the Radiological Environmental Monitoring Program (REMP).

~.o 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....

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. E bar was 0.433 mev per disintegration.

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 percent at the 95 percent confidence level.

The percent of ODCM limit for fission and activation gases (air dose) was determined for locations 1 through 9 and was based on quarterly limits of ten (10) millirads.for= beta"and-five'(5) millirads for gamma. Locations 1 through 9 were used to determine the most restrictive value to be used in Table 3-4 for each quarter.

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

The Auxiliary Boiler and associated heating steam system has been included in the Offsite Dose Calculation Manual (ODCM) as a possible unmonitored source of radioactive effluent when in operation. Its operation as a contaminated system should be at or below 2 E+06 picocuries per liter in the Auxiliary Boiler water. Tritium is the primary radionuclide present; the estimated steam leakrate, determined by the difference between makeup and blowdown waters, would have produced (0.3 percent of the Turbine Building Tritium releases.

Operation of the Auxiliary Boiler as a contaminated system does not increase the probability of the occurrence of an accident previously evaluated because safe shutdown and accident occurrence are not directly affected by its operation. Periodic sampling of the concentration of Tritium in the Auxiliary Boiler water will be tracked and trended to assure compliance to the 2 E+06 picocurie per liter source term.

Three strontium quarterly composite samples for the first quarter of the ye'ar, were lost due to the lack of chemical yield factors.

The results for the Turbine Building and two of the three Radwaste Building vents were lost, PER 293-422 was initiated.

The strontium values from the previous quarter were used for effluent calculations. The strontium levels for the following quarter were also compared with the previous quarter. There was no indication of a change in release rate for the quarter in which the sample data was lost. Strontium levels are an indication of a levelized release.

Concern about the release of Tritium from steam vents and its condensation onto roof surfaces was addressed in PER 293-050.

The concern was addressed in ODCM amendment 14, August 1993, which discussed the design bases of the HVAC system and its environmental effects. The effluent condensations due to natural events allows water to be sent to a storm-drain pond; as stated, on Page 2 of this report, the radiological consequences are insignificant.

Recalibration of the REA Elevated Release Duct Isokinetic Flow and Sampling Control System by a maintenance routine was missed and identified by PER 293-1421. The system surveillance for flow control was carried out and found still in- tolerance. The maintenance task was completed and the system returned to service.

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

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 levels. The meteorological data is a composite ftfile and 245 ft from both the manual and automated data recovery systems for the calendar year 1993.

The year 1993 was drier, warmer and the winds calmer than 1992.

Precipitation was near normal for 1993 with the occurrence of fog and haze and blowing dust much less than 1992. There were few arctic outbreaks of cold air. 1993 was very rainy in the fall. Snowfall and rain were below normal. In summary, the dispersive environment for WNP-2 for 1993 was below normal.

The automated data recovery system continued to function at greater than 90 percent joint data recovery when power was provided by WNP-2 to the meteorological tower system. Power outages contributed to a total data recovery near 90 percent for 1993. All significant outages coincided with scheduled and unscheduled power outages at WNP-2. Lightning strikes and thunderstorms were of minor concern and had no significant effect on meteorological tower operations. Backup alternative power was added in 1993.

Tables 5-1 through 5-8 list the joint frequency distributions at the 5-10 33 ft and the 245 ft levels for 1993 by quarter with 5-9 and listing the annual joint frequency distributions for 1993.

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 1993 as the xeleases were random in time.

Calibrations performed in 1993 produced no values exceeding WNP-2 FSAR meteorological equipment tolerances. Therefore, no corrections have been applied to the raw data.

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 3.3E-04 mrem/yr, thyroid dose of 5.4E-05 mrem/yr and an organ dose value of 4.8E-04 mrem/yr.

The population doses at this location showed a total body value of 8.5E-04 person-rem, thyroid dose of 8.7E-05 person-rem and an organ value of 1.5E-03 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 1.1E-03 mrem. The annu'al thyroid dose was 3.1E-03 mrem and the maximum dose to any other organ was 1.6E-03 mrem.--The -air dose-contribution-was -as follows; Beta air dose was 1.2E-03 mrad and the Gamma air dose was 1.9E-03 mrad. The direct radiation contribution from TLD results calculated to an average of 1.6E-01 mrem per eight hour period.

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 (4.2 miles in a East Southeasterly direction). The NRC GASPAR II computer code with annual source terms and XOQDOQ meteorological 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 2.2E-02 mrem. The annual thyroid dose was 6.3E-02 mrem and the maximum dose to any other organ was 2.3E-02 mrem. Exposure pathways were ground, vegetable and inhalation. The air dose contribution was as follows; Beta air dose was 2.9E-03 mrad/yr and the Gamma air dose was 3.2E-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 2.0E-02 mrem. The annual child age group thyroid dose was 5.6E-02 mrem and the maximum dose to any other organ for the child age group was 2.0E-02 mrem. The annual Beta air dose was 2.4E-03 mrad and the Gamma air dose was 2.5E-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 mrem.

II computer run showed a total body dose of 5.0E-04 The annual thyroid dose was 1.3E-04 mrem and the maximum dose to any other organ was 1.3E-03 mrem.

The direct radiation contribution showed no significant amount above normal background. The 1993 average TLD summary was 91 mrem per year.

EFFLUENT.RPT/RAD1

Additional Basis To Allow POC To Confirm SCN NO.93-093 1~ The limitation of credit for discharge flow to 2.0 cfs for dose calculation is made to bring the ODCM into compliance with NUREG 0133 and commitments in the LBD, and to ensure that the doses calculated will agree with the values generated by the LADTAP II program. This change is conservative, and while increasing the value of the dose calculated by the ODCM methodology, will not result in any increase in the actual value of the dose to the public. This change does not alter the limits or design basis for radioactive releases.

2. The clarification of the method for calculating the Radiation Monitor setpoint does not change the actual method the setpoint is calculated. The changes correct a previous omission of one factor used in the calculation, and clarify the use and calculation method of the Alarm setpoint and the Alarm/Trip setpoint.

3 ~ The relocation of one environmental sample point and the addition of a new sample point will not alter any plant effluent or setpoint calculation. The changes merely reflect the changes in the physical environment surrounding WNP-2.

4 ~ Various editorial changes.

Item gl above will change the values calculated for effluent dose calculation, but will not adversely impact the accuracy or reliability of effluent dose or setpoint calculations.

Item g2 above changes the setpoint, calculation formula given in the ODCM, but does not change the actual value calculated.

Items g3 and g4 have no affect on the effluent dose or setpoint calculation.

8.0 REVISIONS TO THE PROCESS CONTROL PROGRAM PCP The Process Control Program (PCP) was revised during this reporting period. The changes were for the most part minor clarifications or rewordings, however, descriptions of the more significant changes follow.

A. The number of waste streams listed in the PCP procedure was changed from a total of eight, to six primary streams with examples of additional streams that may be generated from time-to-time.

B. The description of reactor coolant trending was expanded to add I-134 as an indicator of fuel failure or other changes which could affect scaling factors..

C. The basis for the tritium concentration of radwaste, which was previously scaled to Cs-137 if tritium was detected in offsite 10CFR61 sample analysis and if Cs-137 was detected in in-house waste stream sample analysis, was changed to scale directly to the reactor coolant tritium concentration.

D. A description of second order scaling was added.

The WNP-2 Process Control Program is proceduralized in PPM 1.12.2 of the Plant Procedures Manual.

9.0 NEW OR DELETED LOCATIONS FOR DOSE ASSESSMENTS AND OR ENVIRONMENTAL MONITORING LOCATIONS 9.1 There was one new location identified during this reporting period which required dose calculations. It is located 7.2 miles ESE and provides for a cow milk dose pathway.

9.2 One additional environmental monitoring location was added for cow milk at 7.2 miles ESE during this reporting period for dose calculations. Amendment, 15 to the ODCM furnishes revised Figures and Tables to provide consistency with the current Radiological Environmental Monitoring Program (REMP). A complete copy of the ODCM has been included as per Section 7.4 of this report.

9.3 There was one environmental monitoring sample type deleted during this reporting period which consisted of cow milk obtained from-6;4- miles SE -(Station 40).--The-owner sold their cow. A monitoring site (Station 59) at 9. 6 miles SE was discontinued as a cow milk location due to owner quitting the dairy business.
