1.0 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 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 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 1996 was 1.67E+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.

,f 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.

A program of processing small batches of containerized liquids collected from plant systems and operational activities has been initiated. This program permits us to segregrate high impurity, low activity liquid waste from the plant radwaste systems, and process it seperately for discharge. The result of this program is a significant reduction in discharged volume and radioactivity. Eleven of these liquid batch discharges had a duration of less than 30 minutes due to their small volume.

There were no abnormal releases.

d 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 0.763 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 effluent monitor was out of service for more than thirty days.

The monitor was out of service from February 2, 1996, to June 23, 1996, for a total of 142 days. The monitor was rendered inoperable by the failure of the sample pump due to overheating. The outage was extended as a result of an engineering evaluation that determined that flow restriction in the sample flow path caused excessive load on the sample pump. The flow restrictions were downstream of the iodine and particulate samplers, and did not affect the ability of the system to obtain a representative sample.

The excessive load shortened the pump's operational life sufficiently to potentially impact on its ability to meet its post accident function according to Regulatory Guide 1.97. The flow restrictions were a result of a design deficiency, rather than an operational failure, and therefore it was necessary to redesign the sample flow path to reduce the amount of restriction. The design and modification process resulted in the extended outage of the monitor. During the monitor outage, all ODCM required compensatory measures were completed. At no time during this monitor outage was any radioactive noble gas detected in this effluent pathway. No radioactive noble gas was measured above minimum detection limits in this effluent pathway during the entire calendar year of 1996. (Reference PER 296-0103-02.)

The Main Plant Vent release monitor, required by ODCM 6.1.2.1-1, instrument 3, was inoperable for more than 30 days between May 26, 1993, and July 15, 1993. This inoperablity was due to the installation of a new stack monitoring system, but was not reported in the next Radioactive Effluent Release Report, as required. This failure to report the extended outage was discovered on May 28, 1996, during an internal trend evaluation of effluent monitor outages. (Reference PER 296-0333-01.)

The accident range gaseous effluent monitors, PRM-RE-1B and PRM-RE-1C were incorrectly calibrated during their initial primary calibration in July 1993, resulting in a non-conservative efficiency factor. This was discovered on March 21, 1996, as a part of an internal evaluation of the monitor's compliance with applicable standards. Until this time, the ODCM required alarm function for the normal range monitor was based on the intermediate range detector, PRM-RE-1B. The non-conservative efficiency factor resulted in an alarm setpoint that was higher than is required by the ODCM. A review of effluent records indicates that WNP-2 effluents via this pathway did not at any time exceed a small fraction of the offsite dose limits. Subsequent to this discovery, the alarm function was relocated to the low range monitor, PRM-RE-1A, which was properly calibrated during its primary calibration. This condition was reported at the time of the discovery, and a Notice of Violation was issued. Refer to NRC Inspection Report NO. 50-397/95-15 for additional information. (Reference PER 296-0176-08.)

During an internal evaluation of compliance to effluent monitor surveillance requirements, it was discovered that the quarterly Channel Functional Test (CFT) required by ODCM 6.1.2.1.1-1, instrument 3.d, Reactor Building Effluent Flow Rate Monitor, had not been performed between March 29, 1995, and June 19, 1996. This failure to perform the surveillance was caused by the incorporation of the CFT instructions into the channel calibration procedure, and the subsequent cancellation of the CFT procedure. The surveillance frequency for the channel calibration should have been changed to quarterly then, but was not. The instrument was declared inoperable when the failure was discovered on June 18, 1996. The CFT was completed, and the instrument was returned to service on June 19, 1996. The frequency of the channel calibration procedure has been changed to quarterly. (Reference PER 296-0504-03.)

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 the 33 ft and 245 ft above ground level (AGL) elevations. The meteorological data is a composite file from both the manual and automated data recovery systems for the calendar year 1996. Data archives were moved this year from a PRIME Computer System to the Supply System's Local Area Network.

Calendar year 1996 was the second wettest year on record. Total precipitation measured at the Hanford Meteorology Station was 12. 19 inches, 195% of the normal 6.26 inches, Snowfall for 1996 was above normal. The period of January through March received snowfall 371% above normal and the two month period of November and December had snowfall 460% above normal. Temperatures for 1996 were, on the average, slightly lower than normal. The average temperature for 1996 was 52.3', which is 1.0' below normal. The occurrence of fog, haze and blowing dust in 1996 was nearly the same as in 1995. In summary, the dispersive environment for WNP-2 for 1996 was near normal.

Joint data recovery for 1996 was 97.3%. 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 AGL for 1996, by quarter. Table 5-9 and 5-10 list the annual joint frequency distribution for those levels for 1996. 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 1996 as the releases were random in time.

Calibrations performed in 1996 produced no values exceeding WNP-2 FSAR meteorological equipment tolerances. Data below 0.07 MPH has been determined to result from system malfunction and is not included in the results.

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 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 .

3.70E-05 mrem. The annual thyroid dose was 3.79E-05 mrem and the maximum dose to any other organ was 4.55E-05 mrem. The air dose contribution was as follows; Beta air dose was 4.60E-03 mrad and the Gamma air dose was 1.72E-02 mrad. The direct radiation contribution from TLD results calculated to an average of 9.30E-02 mrem per eight hour period.

The 1996 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 1996 was less than 10 mrem.

The report issued for calendar year 1995 did not include the values for total body and skin dose, These values were calculated and verified to be within limits at the time the report for 1995 was issued. This omission was identified by WNP-2 Quality Assurance in an audit of the Radioactive Effluents program in November 1996. Corrective actions have been initiated to prevent recurrence. (Reference PER 296-0724-02.) The values omitted from the 1995 report are listed below.

The highest annual skin dose at the site boundary for calendar year 1995 was 2.02E-03 mrem.

The highest annual total body dose at the site boundary for calendar year 1995 was 1.57E-03 mrem.

The highest annual skin dose beyond the site boundary for calendar year 1995 was 1.54E-03 mrem.

The highest annual total body dose beyond the site boundary for calendar year 1995 was 1.09E-03 mrem.
