0 1.0 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 LT ID EFFLUENT 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 prior to sampling. A representative sample was obtained and analyzed for each batch release. A composite of the batch samples for each month are analyzed for tritium, and a composite sample for each quarter is 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 1995 was 1.11E+05 cubic feet per second.

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.

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 abnormal releases.

On June 22, 1995 it was discovered that the methodology for determining the liquid effluent monitor setpoint was non-conservative. This method had been implemented in October, 1994. A thorough review of all liquid discharges in the intervening period showed that no discharge exceeded established regulatory, ODCM, or administrative limits. At the time the non-conservative calculation was discovered, the monitor was declared inoperable, in accordance with ODCM 6.1.1.1.a. The appropriate compensatory measures were initiated. This monitor remained out of service until an extensive review of the discharges made with the incorrect setpoint and the cause of the incorrect setpoint methodology was determined. This resulted in an outage period of greater than 30 days. (Reference PERA 295-0781-01, PERA 295-0617-01.)

~h 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 -'round 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 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 0.577 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 are estimated from offgas post treatment samples. Turbine building noble gas concentrations are estimated from steam jet air ejector samples and scaled to effluent tritium.

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 on Table 3-0.

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,

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.

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

Between April 17, 1995 at 13:19, and April 18, 1995 at 23:30, the required sample to compensate for an inoperable Radwaste building effluent monitor was not taken. This building has three separate exhaust ducts and fans. Two fans are normally operating.

The sample pump had failed in the normal effluent monitor, and continuous samples were being collected from the two operating effluent fans. On April 17, 1995, at 13:19, one of the operating effluent fans was switched off, and another was switched on. This was done without notifying Chemistry, the department responsible for sample collection, When this condition was discovered on April 18, 1995, at 23:30, the sampler was moved from the non-operating fan to the operating fan. A change to the Radwaste building exhaust system operating procedure has been made to preclude the recurrence of this event. There were no operational events or occurrences that would indicate that there was any change to the normal building effluent during this period of time. The air effluent activity has been estimated to be constant, for the purposes of effluent activity and dose calculation. (Reference PERA 295-0352-02.)

On July 11, 1995 the sample flow instrumentation for the Reactor building effluent monitor failed the channel functional test. This was reported to the control room, but due to a recent change in the equipment piece numbers (EPN) on these instruments, the ODCM required compensatory measure was incorrectly identified. Subsequent review revealed this error, and the correct compensatory measure was identified and initiated. The correct compensatory measure was to install auxiliary sampling equipment. The ODCM requires that this be completed within four hours. The auxiliary sampling equipment was not installed for five and one-half hours. The recent change in the EPN had been incorporated into plant documents properly, but the channel functional test which failed the test had been initiated prior to the change. It retained the old EPN. There were no operational events or occurrences that would indicate that there was any change to the normal building effluent during this period of time. The air effluent activity has been estimated to be constant, for the purposes of effluent activity and dose calculation. (Reference PERA 295-0839-00.)

EPF-95.RPF

The iodine and particulate sampler and sample flow instrumentabon required by ODCM 6.1.2.1, Table 6.1.2.1-1.3, was out of service for more that 30 days. This extended outage was due to the installation of a new sampling system. When the system was removed for modification, the corresponding compensatory measures were initiated, On June 3, 1995 at 17:55 the auxiliary sampling equipment, which had been installed to compensate for the inoperability of the Reactor building effluent sampler and sample flow instrumentation, was removed from service to support post modification testing. The auxiliary sampling equipment was disconnected for less than four hours, which is the allowable outage time for the installed equipment, but was not allowed for the auxiliary sampling equipment. When this was discovered, the auxiliary sampling equipment was returned to operation. Subsequent to this event the ODCM compensatory measure was amended, as per ODCM amendment 19, to permit this 4 hour4.62963e-5 days 0.00111 hours 6.613757e-6 weeks 1.522e-6 months outage for the auxiliary sampling equipment. (Reference PER 295-0697-01, PER 295-0342-01.)

On July 20, 1995 the auxiliary sampling equipment, which had been installed to compensate for the failure of the sample pump for the Reactor building particulate and iodine sampler, failed. It was not possible to repair the auxiliary sampling equipment within the allowable four hour period, so the Reactor building exhaust system was secured. This occurred at 07:46 hours. Without the Reactor building. exhaust air flow, several areas of the Reactor building began to approach thermal limits, which could have resulted in a reactor scram, resulting in a substantial increase in the effluent activity, so the Shift Manager directed that the Reactor building exhaust system be restored to operation. This occurred at 07:56 hours. The Reactor building exhaust system operated without the required auxiliary sampling equipment for sixteen minutes, until the repairs were complete and the sampling equipment was restored to operation. There were no operational events or occurrences that would indicate that there was any change to the normal building effluent during this period of time. The air effluent activity has been estimated to be constant, for the purposes of effluent activity and dose calculation. (Reference PERA 295;0868-00,)

On October 19, 1995 the Reactor building effluent low range activity monitor required by ODCM 6.1.2.1, Table 6.1.2.1-1.3a, failed. This monitor remained out of service for more than 30 days. It was returned to service on December 27, 1995.

During the monitor's outage, appropriate compensatory measures were completed.

The replacement for the failed part, which was stored in the onsite warehouse, had been damaged in shipping, and this had not been recognized in the receipt inspection.

This extended the system outage because this part is unique to this system, and it had to be returned to the manufacturer for repair. In order to prevent recurrence of this event, the vendor has improved the shipping container, and we have improved our receipt inspection criteria, (Reference PER 295-1207-01.)

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 levels. The meteorological data is a composite file from both the manual and automated data recovery systems for the calendar year 1995. Data is archived on a PRIME Computer System.

Precipitation was much higher than normal in 1995. Total precipitation measured at the Hanford Meteorology Station was 12.31 inches, 197% of the normal 6.26 inches.

However, snowfall for 1995 was approximately half that of normal an approximate total of 7 inches. Temperatures for 1995 were cooler than 1994 but were still slightly above normal. The occurrence of fog and haze and blowing dust in 1995 was nearly the same as in 1994. In summary, the dispersive environment for WNP-2 for 1994 was near normal.

Joint data recovery for 1994 was 93.9%. Scheduled and unscheduled 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 1995. Table 5-9 and 5-10 list the annual joint frequency distributions for those levels for 1995. 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 1995 as the releases were random in time.

Calibrations performed in 1995 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.

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 doses to the average individual and 50-mile population doses from liquid effluents. All doses were I! 'fl calculated using the NRC LADTAP II computer code.

-Th NRCGAIPARII 2 d I I I and beyond the site boundary. Table 6-5 lists the annual 50-mile dose using values obtained from the ALARA annual integrated population dose summary (person-rem).

d 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 utilized quarterly and annual meteorological data and site specific input parameters.

6.1 Ex o ret "AMem erof h P li" 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 2.51E-05 mrem. The annual thyroid dose was 3.90E-05 mrem and the maximum dose to any other organ was 3.59E-05 mrem. The air dose contribution was as follows; Beta air dose was 9.24E-03 mrad and the Gamma air dose was 1.96E-02 mrad. The direct radiation contribution from TLD results calculated to an average of 2.40E-01 mrem per eight hour period.

The 1995 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 1995 was less than 10 mrem.

1. 0 INTRODUCTION The purpose of this manual is to provide the information and methodologies to be used by the Washington Public Power Supply System to satisfy the requirements of 10 CFR 20.106, 40 CFR Part 190, 10 CFR 50.36a, and Appendix I to 10 CFR Part 50.

2.0 LI UID EFFLUENT DOSE CALCULATION The U.S. Nuclear Regulatory Commission's computer program LADTAP II can be used for dose analysis for liquid radioactive effluents from WNP-2 into surface waters. The analyses estimate radiation dose to individuals, population groups, and biota from ingestion (aquatic foods, water, and terrestrial irrigated foods) and external exposure (shoreline, swimming, and boating) pathways. The calculated doses provide for determining compliance with Appendix I to 10 CFR Part 50.

2.1 Introduction Liquid radwaste released from WNP-2 will meet 10 CFR 20 limits at the point of discharge to the Columbia River. Actual discharges of liquid radwaste effluents will only occur on a Batch Basis, and the average concentration at the point of discharge will be only a small percentage of the allowed limits.

A simplified block diagram of the liquid waste management system and effluent pathways is contained in Figure 2-1. Solid radioactive wastes are disposed of by way of an approved disposal site. A simplified block diagram of the solid radwaste system is described in Figure 2-2.

The cumulative quarterly dose contributions due to radioactive liquid effluents released to the unrestricted areas will be determined once every 31 days using the LADTAP II computer code.

AMENDMENT NO. 15 CONTROLLED COPY OCTOBER 1993 The dose contributions will be calculated for all radionuclides identified in the released effluent based on guidelines provided by NUREG-0133.

The methods for calculating the doses are discussed in Section 2.4 of this manual.

2.2 Radwaste Li uid Effluent Radiation Monitorin S stem This monitoring subsystem measures the radioactivity in the liquid effluent prior to its entering the cooling tower blowdown line.

All radwaste effluent passes through a four-inch line which has an off-line sodium iodide radiation monitor. The radwaste effluent flow, variable from 0 to 190 gpm, combines with the 36-inch cooling water blowdown line, variable from 0 to 7500 gpm and is discharged to the Columbia River with a total flow based on MPC, total, and cooling water flushing needs.

The radiation monitor is located on the 437'evel of the Radwaste Building and has a minimum sensitivity of 10 yCi/cc for Cs-137. The radiation indicator has seven decades of range.

2.3 10 CFR 20 Release Rate Limits The requirements pertaining to discharge of radwaste liquid effluents to the unrestricted area are specified in Requirement for Operability 6.2. 1. 1 (3.ll.l.l):

"The concentration of radioactive material released from the site to unrestricted areas shall be limited to the concentrations specified in 10 CFR 20, Appendix B, Table II, Column 2 for radionuclides other than noble gases, and 2 x 10 " pCi/ml total activity concentration for all dissolved or entrained noble gases."

CONTROLLED COPY AMENDMENT NO. 15 OCTOBER 1993 In order to comply with the requirements stated above, limits will be set to assure that blowdown line concentrations do not exceed 10 CFR 20, Appendix B, Table II, Column 2 at any time.

2.3. 1 Pre-Release Calculation The activity of the radionuclide mixture and the liquid effluent discharge rate will be determined in accordance with Supply System procedures. The effluent concentration is determined by the following equation:

Ci x fw Conc,.=

ft where:

Conc; Concentration of radionuclide i in the effluent at point of discharge - pCi/ml.

C; Concentration of radionuclide i in the batch to be released

- pCi/ml.

fw Discharge flow rate from sample tank to the blowdown line-variable from 0 to 190 gpm.

fb Blowdown flow rate - variable from 0 to 7500 gpm.

Total discharge (ft fb + fw) flow rate - variable from 0 to 7690 gpm.

The calculated concentration in the blowdown line must be less than the concentrations listed in 10 CFR 20, Appendix B. Before releasing the batch to the environment, the following equation must hold:

CONTROLLED COPY AMENDMENT NO. 15 OCTOBER 1993 (Conc i/MPC i) 1 (2) ie1 where:

Conc; The concentration of radionuclide i in the effluent at the point of discharge into the river.

MPC; Maximum permissible concentration of nuclide i as listed in 10 CFR 20, Appendix 8, Table II.

Total number of radionuclides in the batch.

2.3.2 Post-Release Calculation The concentration of each radionuclide in the unrestricted area, following the batch release, will be calculated as follows:

The average activity of radionuclide'i during the time period of the release is'ivided by the Plant Discharge Flow/Tank Discharge Flow ratio yielding the concentration at the point of discharge:

Ckx fw Conc .

ik (3) where:

Conc, The concentration of radionuclide i in the effluent at the point of discharge during the release period k - (pCi/ml).

Cik The concentration of radionuclide i in the batch during the release period k - (pCi/ml).

fw Discharge flow rate from sample tank to the blowdown line

- variable from 0 to 190 gpm.

CONTROLLED COPY AMENDMENT NO. 15 OCTOBER 1993 fb Blowdown flow rate - variable from 0 to 7500 gpm.

Total discharge (ft - fb + fw) flow rate - variable from 0 to 7690 gpm.

To assure compliance with 10 CFR 20, the following relationships must hold:

(Conc.,/HPC,) g 1 (4) ii1 where the terms are as defined in Equation (2).

2.3.3 Continuous Release Continuous release of liquid radwaste effluent is not planned for WNP-2.

However, should it occur, the concentrations of various radionuclides in the unrestricted area would be calculated according to Equation (3) and Equa-tion (4). To show compliance with 10 CFR 20, the two equations must again hold.

2.4 10 CFR 50 A endix I Release Rate Limits Periodic Test and Inspection 6.2. 1.2.1 (4. 11. 1.2) requires that the cumulative dose contributions be determined in accordance with the ODCH at least once per 31 days. Requirement for Operability 6.2. 1.2 (3. 11. 1.2) specifies that the dose to a member of the public from radioactive material in liquid effluents released to the unrestricted area shall be limited to:

~1.5 mrem/Calendar quarter - Total Body and

~5.0 mrem/Calendar quarter - Any Organ.

AMENDMENT NO. 15 CONTROLLED COPY OCTOBER 1993 The cumulative dose for the calendar year shall be limited to:

<3 mrem - Total Body and

~10 mrem - Any Organ.

The maximum exposed individual is assumed to be an adult whose exposure pathways include potable water and fish consumption. The choice of an adult as the maximum exposed individual is based on the highest fish and water consumption rates shown by that age group and the fact that most of the dose from the liquid effluent comes from these two pathways.

The dose contribution will be calculated for all radionuclides identified in the liquid effluent released to the unrestricted area, using the following equation:

Dr = gi (Ai, l~1 g htsCisFs) (5) where:

D7 The cumulative dose commitment to the total body or organ, m

7, from liquid effluents for the total time period g ht,,

1~1 in mrem.

The length of the 8th time period over which C;, and F, are averaged for all liquid releases, in hour s. .

The number of releases for the time period under consideration.

C The average concentration of radionuclide i in undiluted liquid effluent during time period ~t, from any liquid release, in pCi/ml.

AMENDMENT NO. 15 CONTROLLED COPY OCTOBER 1993 A;, The site-related ingestion dose commitment factor to the total body or any organ v for each identified principle gamma and beta emitter listed in Table 2-2, in mrem/hr per pCi/ml-.

The near field average dilution factor for C;, during any liquid waste release. This is defined as the ratio of the maximum undiluted I liquid waste flow during release to the product of the average flow from the-site discharge structure to unrestricted receiving waters times 500.

While the actual discharge structure exit flow is variable from 0 to 17. 1 cfs (0 to 7690 gpm), a maximum flow value of 2.0 cfs will be used for dose calculation purposes in accordance with the NUREG-0133 requirement that the product of the average blowdown flow to the receiving water body, in cfs and the applicable factor (500), is 1000 cfs or less.

The term A; the ingestion dose factors for the total body and critical organs, are tabulated in Table 2-2. It embodies the dose factor, fish bioaccumulation factor, pathway usage factor, and the dilution factor for the plant diffuser pipe to the Richland potable water intake. The following equation was used to calculate the ingestion dose factors:

The values 'of BF, and DF, are listed in Table 2-1. Dilution assumptions, calculations, and LADTAP II input parameters are provided in Radiological Health Calculation Log 92-2.

The quarterly limits mentioned before represent one-half of the annual design objective of Section II.A of 10 CFR 50, Appendix I. If any of the limits (either that of the calendar quarter or calendar year) are exceeded, a special report 'pursuant to Section IV.A of 10 CFR 50, Appendix I, shall be filed with the NRC.

2.4.1 Pro'ection of Doses The projected doses due to releases of WNP-2 radwaste liquid effluents will be calculated for each batch, using Equation (5) or LADTAP II. If the sum of the accumulated dose to date for the month and the projected dose for the remainder of the month exceeds the Requirement for Operability 6.2. 1.3 (3.11.1.3) limits, then the liquid radwaste treatment system shall be used.

This is to ensure compliance with Requirement for Operability 6.2.1.3 (3. 11. 1.3). This Requirement for Operability states that the liquid radwaste treatment system shall be maintained and the appropriate subsystem shall be used if the radioactive materials in liquid waste, prior to their discharge, when the dose, due to liquid effluent release to unrestricted areas when averaged over the month would exceed 0.06 mrem to total body or 0.2 mrem to any organ.

CONTROLLED COPY AHENDHENT NO. 15 OCTOBER 1993 2.5 Radwaste Li uid Effluent Dilution Ratio and Alarm Set pints Calculations 2.5.1 Introduction The dilution alarm ratio and setpoints of the sample liquid effluent monitor are established to ensure that the limits of 10 CFR 20, Appendix B, Table II, Column 2, are not exceeded in the effluent at the discharge point (i.e.,

compliance with Requirement for Operability 6.2. 1. 1 (3. 11. 1. 1), as discussed in section 2.3. 1 of this manual).

The alarm (HI) and the alarm/trip (HI-HI) setpoints for the liquid radwaste effluent monitor are calculated from the results of the radiochemical analysis of the effluent sample. The setpoints will be set into the radwaste monitor just prior to the release of each batch of radioactive liquid.

2.5.2 Hethodolo for Determinin the Haximum Permissible Concentration HPC Fraction Radwaste liquid effluents can only be discharged to the environment through the four-inch radwaste line. The maximum radwaste discharge flow rate is 190 gpm. Prior to discharge, the tank is isolated and recirculated for at least thirty minutes, and a representative sample is taken from the tank. An isotopic analysis of the batch will be made to determine the sum of the HPC fraction (NPC,) based on 10 CFR 20 limits. From the sample analysis and the HPC values in 10 CFR 20, the NPC, is determined using the following equation.

NPC, =g i~ ~ NPC.,

where:

HPC, Total fraction of the Naximum Permissible Concentrations (HPCs) in the liquid effluent waste sample.

C; The concentration of each measured radionuclide i observed by the radiochemical analysis of the liquid waste sample (pCi/ml).

AMENDMENT NO. 121 JUNE 1995 MPC( The limiting concentrations of the appropriate radionuclide i from 10 CFR 20, Appendix B, Table II, Column 2. For dissolved or entrained noble gases, the concentration shall be limited to 2.0E-04 pCi/ml total activity.

The total number of measured radionuclides in the liquid batch to be released.

If the'PC, is less than or equal to 0.8, the liquid batch may be released at any radwaste discharge or blowdown rate. If the HPC, exceeds 0.8, then a dilution factor (Fd) must be determined. The liquid effluent radiation monitor responds proportionally to radioactivity concentrations in the undiluted waste stream. Its setpoint must be determined for diluted releases.

2.5.3 ethodolo for the Deter 'nation of in'm D'tion Factor The measured radionuclide concentrations are used to calculate the dilution factor (Fd), which is the ratio of the total discharge flow rates (RW + CBD) to the radwaste tank effluent flow rate (RW) that is required to assure that the limiting concentrations of Requirement for Operability 6.2. 1. I (3. 11. 1. 1) are met at the point of discharge.

The minimum .dilution factor (Fd) is determined according to:

m i (9)

AMENDMENT NO. 21 JUNE 1995 2.5.4 Hethodolo for the Determination of Li uid Effluent Monitor Set pints Liquid effluents must meet the restrictions at the point of discharge to the river of 1 HPC or less after dilution. Therefore, the Liquid Effluent Monitor setpoint must be determined such that it will terminate a discharge at. less than or equal to that point. The dilution factor must satisfy Equation (10).

Setpoint the radwaste effluent monitor setpoint in pCi/ml.

C is the maximum permissible diluted concentration, in pCi/ml, at the point of release that is in compliance with 10CFR20 Appendix B Table II column 2.

The Liquid Effluent Monitor measures the undiluted effluent, therefore the term CBD + RW RW is used to correct for dilution.

The Hi alarm setpoint is determined to be at the monitor response for the current batch release multiplied by 1.25 to allow for normal variation in the monitor response.

2.7.2 Plant Parameters WNP-2 is a river shoreline site with a variable effluent discharge flow rate 0 to 7690 gpm. The population center nearest WNP-2 is the city of Richland, where drinking water withdrawal takes place. The applicable dilution factor is 50,000, using average river flow.

CONTROLLED COPY AMENDMENT NO. 9 JANUARY 1992 The total allowed activity (A~) is based on limiting WNP-1 well water to less than 1 HPC, of the entire liquid content of the tank spilled to ground and then migrated via ground water to the WNP-1 well. The WNP-1 well is the location of maximum concentration since it is the near est source of ground water and conditions are such that no spill of liquid should reach surface water. The 70-85 foot depth of the water table and the low ambient moisture of the soil requires a rather large volume of spillage for the liquid to even reach the water table in less than several hundred years. However, allowed tank activity (AT) is conservatively based on all liquid radwaste in the tank instantaneously reaching the water table.

The hydrological analysis performed for the WNP-2 FSAR (Section 2.4) deter-mined that the transit time through the ground water from WNP-2 to the WNP-1 well is 67 years for Strontium and 660 years for Cesium. These two radio-nuclides are representative of the radionuclides found in liquid radwaste.

Strontium is a moderate sorber and Cesium strongly sorbs to soil particles.

This calculation conservatively treats all radionuclides as moderate sorbers with a transit time of 67 years.

The concentration of each radionuclide in the well (CWi) is simply the con-centration in the tank (CT;) adjusted for radioactive decay during transit (e"') and divided by the minimum concentration reduction factor (CRF ).

23

CONTROLLED COPY AHENDHENT NO. 14 AUGUST 1993 There are three detectors to measure the activity of each of the three nonradioactive sumps. The monitors are located on the 441'evel of the Turbine Building. The readout meters and recorder are located in the Radwaste Control Room Panel BD-RAD-41. The alarm/setpoint for these detectors is established by design at 80% of the 10CFR Part 20, Appendix B, Table II value for Cs-137. In the event the setpoint is exceeded, the sump discharge will be automatically diverted to the Radwaste system for processing.

, Turbine building sumps, Tl, T2, and T3 are normally routed to the liquid radwaste system. Effluent from these turbine building sumps may be routed to the storm water system if analyses indicate no detectable radioactivity is present. Other inputs to the storm waste system, in addition to rain water, include water treatment filter backwashes, Service Building and Emergency Diesel Generator Building floor drains, HVAC air wash units, and condensed steam from plant steam leaks that collect on rooftops during cool weather.

The storm water system terminates in an unlined depression or pond located 1500 feet northeast of the plant. Releases to the storm drain pond are sampled as part of the Radiological Environmental Honitoring Program. Based on past experience, it is expected that there will be some accumulation of low levels of radioactive materials, particularly tritium, in the pond.

3. 0 GAS OU F U NTS DOS CA CU TIONS The U.S. Nuclear Regulatory Commission's computer program GASPAR II can be used to perform environmental dose analyses for releases of radioactive efflu-ents from WNP-2 into the atmosphere. The analyses estimate radiation dose to individuals and population groups from inhalation, ingestion (terrestrial foods), and external exposure (ground and plume) pathways. The calculated doses provide information for determining compliance with Appendix I of 10 CFR Part 50. This computer code has the subroutine "PARTS" which can be used for calculating dose factors.

The NRC computer program GASPAR II supplements the ODCH in monthly, quarterly and annual dose equivalent determinations from gaseous effluents. The method which is normally employed to calculate the annual dose to the maximally exposed organ sums the dose to the maximally exposed organ for each quarter.

As a result, the maximum annual organ dose may not represent the maximum dose to any one particular organ for that particular year. Actual specific organ doses will be less than or equal'o this calculated value.

Both the ODCH equations and the NRC GASPAR II computer program for estimating the highest dose to any organ for a particular age group provides conservatism in calculating maximum organ doses. This conservatism is recognized and is intentional.

WNP-2 gaseous effluents are released I

on a continuous basis; in addition, batch releases also occui when containment and mechanical vacuum pump purges are performed and when the off-gas treatment system operates in the charcoal bypass mode. The gaseous effluents released from WNP-2 will meet Requirement for Operability at the site boundary.

CONTROLLED COPY AMEHDMEHT NO. ll AUGUST 1992 Figure 3-1 delineates the WNP-2 Site boundary, which for dose calculation pur-poses, is considered circular with a radius of 1.2 miles. There are several low occupancy unrestricted locations within the site boundary. These loca-tions, with the exception of the WNP-2 visitor center, are not continuously controlled by the Supply System. The locations are:

1. Wye burial site - normally controlled by DOE.

2. DOE train - two railroad lines pass through the site (approximately 3 miles of line). According to DOE, the train makes one round trip a day, through the site at an average speed of 20 mph, 5 days a week, 52 weeks/year.

3. BPA Ashe Substation - occupied 2080 hour0.0241 days 0.578 hours 0.00344 weeks 7.9144e-4 months s/year . These people are not normally controlled by the Supply System but are involved in activities directly in support of WNP-2.

34a

AMENDMENT NO. 21 JUNE 1995

4. WNP-2 - Supply System Visitor Center - assumed occupied 8 hrs/yr by non-Supply System individuals.

5. WNP-1 - occupied 2080 hr s/yr. This location is controlled by the Supply System. However, activities are not in direct support of WNP-2.

6. WNP-4 - occupied 2080 hrs/yr. This location is controlled by the Supply System. However, activities are not in direct support of WNP-2.

All other locations listed in Figure 3-1 support WNP-2 activities and are controlled by the Supply System. Figure 3-2 provides a simplified block diagram of the gaseous radwaste system for the reactor, turbine and radwaste buildings. Figure 3-3 provides a simplified block diagram for the off-gas treatment system.

Air doses and doses to individuals at these locations were calculated based on the NRC GALE code design base mixture, location specific estimated occupancy, and 'X/Qs from XOQDOQ. (Note: Desert Sigmas were used in calculating X/Q and D/Q values, and are listed in Table 3-10 and 3-11). These doses are listed in Tables 3-16 and 3-17 along with the doses to the maximum exposed individual.

The most likel ex osed member o the ublic is considered to be residing in Taylor Flats (4.2 miles ESE .of WNP-2). This is the closest residential area with the highest X/Q and D/Q values.

The Auxiliary Boiler supplies heating steam to the Reactor, Radwaste, Turbine and Service buildings when Seal Steam Evaporator B is not in operation. The Auxiliary Boiler and associated heating steam system vents to the atmosphere and provides a possible unmonitored source of radioactive effluent when in operation. Samples have shown 2.0 E+06 picocuries per liter of tritium activity to be present within the Auxiliary Boiler system. Using NRC Regulatory Guide 1. 109 methodology with FSAR Low Population Zone (LPZ) X/Q 35

AMENDMENT NO. 23 SEPTEMBER 1995 values and assuming one gallon per minute (1 gpm) makeup flowrate for 180 days plus a one time complete boil-off of the total water inventory, the dose contribution from tritium would be less than one tenth of a millirem per year

(<0. I mrem/yr). Figure 3-4 provides a simplified diagram for the Auxiliary Boiler; Tritium in the form of tritiated water vapor is released to the environment through monitored/sampled effluent pathways. Under certain meteorological conditions, the tritiated water vapor may condense onto surfaces such as rooftops and parking lots. Subsequently, this condensed, recaptured tritiated water may be carried with precipitation into the Storm Drain Pond (SDP) which serves as a collection point for storm drainage. In addition, tritiated water vapor released onto WNP-2 buildings may condense on cold metal exterior walls and run onto adjacent rooftops, to be carried with precipitation to the SDP.

Influent to the SDP is continuously sampled and periodically analyzed for tritium content.

3.2 Gaseous Effluent Radiation Monitorin S stem 3.2.1 Main Plant Release Point The Main Plant Release is instrument monitored for gaseous radioactivity prior to discharge to the environment via the main plant vent release point.

Particulates and iodine activity are accumulated in filters which will be changed and analyzed as per Periodic Test and Inspection 6.2.2. 1.2 (4. 11.2. 1.2) and Table 6.2.2. 1.2-1 (4. 11-2). The effluent is supplied from:

the gland seal 35a

AMENDMENT NO. 18 APRIL 1995 exhauster, mechanical vacuum pumps, treated off gas, standby gas treatment, and exhaust air from the entire reactor building's ventilation.

Two 100-percent capacity vanaxial fans supply 80,000 CFM ventilation air. One is normally operating, the other is in standby. The radiation monitors are located on the ventilation exhaust plenum.

Effluent monitoring consists of a gamma spectroscopy system utilizing three in-line detectors to provide an isotopic analysis of the Elevated Release effluents. The low range (PRM-RE-1A) is a high efficiency, cryogenically cooled, high purity germanium detector located inside the duct at elevation 611'o monitor low level normal operation radioactivity. Low range response is approximately 8.0 x 10'ps/pCi/cc. Two additional detectors (PRH-RE-1B and PRM-RE-1C) are mounted in lead enclosures at elevation 618'7" for post-accident monitoring. They provide a range of 10'o 10 pCi/cc with one decade of overlap. All three have gross gamma Log Count Rate Heter ranges of 10 to 10 cps. PRM-LCRH-lA, -1B, and 1C are located on Radwaste Bldg.

elevation 525'n PRM-CP-1 and are recorded at PRM-RR-3 on BD-RAD-24 in the Main Control Room. Isotopic information from all three detectors is available at E-CP-H13/P814 on PRM-COMP-3. Power is from battery-backed, reliable 120 VAC buses. This monitor has no control function but annunciates in the Hain Control Room. The alarm will initiate proper action as defined in the WNP-2 plant procedures.

3.2.2 Radwaste Buildin Ventilation Exhaust Monitor The radwaste building ventilation exhaust monitoring system monitors the radioactivity in the exhaust air prior to discharge. Radioactivity can originate from: radwaste tank vents, laboratory hoods, and various cubicles housing liquid process treatment equipment and systems.

The radwaste building exhaust system has three 50-percent capacity exhaust filter units of 42,000 cfm capacity. Each exhaust unit has a medium-efficiency prefilter, a high efficiency particulate air filter (HEPA) and two centrifugal fans. Total exhaust flow will vary as the combined exhaust unit maintains a radwaste building differential pressure of -0.25 inches H,O to the environment.

Particulate and iodine air sample filters are changed weekly for laboratory 36

The turbine building main exhaust system consists of four roof-mounted cen-trifugal fans which draw air from a central exhaust plenum. Three fans operate, with one in standby to provide a flow of 360,000 cfm during summer months, and two fans operate with two in standby to provide a flow of 240,000 cfm during winter months.

A representative sample is extracted from the exhaust vent and passed through a particulate and charcoal filter. The air sample then passes to a beta scintillator.

The beta scintillators are mounted in lead shielded chambers. The low range beta scintillator has an approximate response of 80 cpm/pCi/cc to Kr-85, and 50 cpm/pCi/cc to Xe-133 and a meter range of 10 - 10 cpm.

3.6 Calculation of Gaseous Effluent Monitor Alarm Set pints 3.6.1 Introduction The following procedure is used to ensure that. the dose rate in the unrestricted areas due to noble gases in the WNP-2 gaseous effluent do not exceed 500 mrem/yr to the whole body or 3000 mrem/yr to the skin. The initial setpoints determination was calculated using a conservative radionuclide mix obtained from the WNP-2 GALE code. While the plant is operating and sufficient measurable process fission gases are in the effluent, then the actual radionuclide mix will be used to calculate the alarm setpoint.

3.6.2 Set oint Determination for all Gaseous Release Paths The setpoints for gaseous effluent are based on instantaneous noble gas dose rates. Sampling and analysis of radioiodines and radionuclides in particulate form will be performed in accordance with Requirement for Operability to ensure compliance with 10 CFR 20 and 10 CFR 50 Appendix I limits. The three release points will be partitioned such that their sum does not exceed 100 percent of the limit. Originally, the setpoints will be set at 40 percent for 56

CONTROLLED COPY AMENDMENT NO. 11 AUGUST 1992 the Reactor Building, 40 percent for the Turbine Building and 20 percent for the Radwaste Building. These percentages could vary at the plant discretion, should the operational conditions warrant such change. However, the combined releases due to variations in the setpoints will not result in doses which exceed the limit stated in Requirement for Operability. Both skin dose and whole body setpoints will be calculated and the lower limit will be used.

AMENDMENT NO. 9 CONTROLLED COPY JANUARY 1992 4.0 COMPLIANCE WITH 40 CFR 190 4.1 Re uirement For 0 erabilit Requirement for Operability 6.2.4.1 (3. 11.4) states, "The annual (calendar year) dose or dose commitment to any Member of the Public, due to release of radioactivity and radiation, from uranium fuel cycle sources shall be limited to less than or equal to 25 mrems to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems."

4.2 ODCM Methodolo for Determinin Dose and Dose Commitment from Uranium Fuel C cle Sources The annual dose or dose commitment to a Member of the Public for the uranium fuel cycle sources is determined as:

a) Dose to the total body due to the release of radioactive materials in liquid effluents.

b) Dose to any organ due to the release of radioactive materials in liquid effluents.

c) Air doses due to noble gases released in gaseous effluents.

d) Dose to any organ due to the release of radioiodines, tritium and radio-nuclides in particulate form with half-lives greater than 8 days in gaseous effluents.

e) Dose due to direct radiation from the plant.

The annual dose or dose commitment to a Member of the Public from the uranium fuel cycle sources is determined whenever the calculated doses from the release of radioactive materials in liquid or gaseous effluents exceed twice the limits in Requirement for Operability 6.2.1.2.a, 6.2.1.2.b, 6.2.2.2.a, 6.2.2.2.b, 6.2.2.3.a, or 6.2.2.3.b (3.11.1.2.a, 3.11.1.2.b, 3.11.2.2.a,

3. 11.2.2.b, 3. 11.2.3.a, or 3. 11.2.3.b). Direct radiation measurements will also be made to determine if the limits of Requirement for Operability 6.2.4. 1 (3. 11.4) have been exceeded.

92

0 AMENDMENT NO. 18 APRIL 1995 4.2.

~ ~ 1 Total Dose from Li uid Effluents The annual dose to a Member of the Public from liquid effluents will be determined using NRC LADTAP II computer code, and methodology presented by Equation (5) in Section 2.4. It is assumed that dose contribution pathways to a Member of the Public do not exist for areas within the site boundary.

4.2.2 Total Dose from Gaseous Effluents The annual dose to a Member of the Public from gaseous effluents will be determined using NRC GASPAR II computer code, and methodology presented by Equations (10), (11) and (13) in Section 3.4. Appropriate atmospheric dispersion parameters will be used.

4.2.3 Direct Radiation Contribution The dose to a Member of the Public due to direct radiation from the reactor plant will be determined using thermoluminescent dosimeters (TLDs)'or may be calculated. TLDs are placed at sample locations and analyzed as per Table 5-1. The direct radiation contribution will be documented in the Radioactive Effluent Release Report submitted 60 days after January I of each year.

TLD stations 1S-16S are special interest stations and will not be used for direct radiation dose determinations to a Member of the Public.

5.0 RADIOLOGICAL ENVIRONMENTAL MONITORING Radiological environmental monitoring is intended to supplement radiological efFluent monitoring by verifying that measurable concentrations of radioactive materials and levels of radiation in the environment are not greater than expected based on effluent measurement and dose modeling of environmental exposure pathways. The Radiological Environmental Monitoring Program (REMP) for WNP-2 provides for measurements of radiation and radioactive materials in those exposure pathways and for those radionuclides for which the highest potential dose commitment to a Member of the Public would result due to plant operations.

93

AMENDMENT NO. 9 CONTROLLED COPY JANUARY 1992 The WNP-2 REHP is designed to conform to regulatory guidance provided by Regulatory Guide 4. 1, 4.8 and the Radiological Assessment Branch Technical Position (BTP), taking into consideration certain site specific character-istics. The unique nature of the WNP-2 site on Federally owned and admin-istered land (Hanford Reservation) dedicated to energy facilities, research, waste management and as a natural reserve, forms the basis for many of the site specific parameters. Amongst the many site specific parameters con-sidered is demographic data such as:

1) No significant clusters of population including schools, hospitals, business facilities or primary public transportation routes are located within 8 km (5 mile) radius of the plant.

2) No private residences are located on the Hanford Reservation.

3) The closest resident is east of the Columbia River at a distance of approximately 4 miles.

Radiological environmental monitoring activities implemented by PPH 1. 11. 1 "Radiological Environmental Monitoring Program (REHP) Implementation Proce-dure", as detailed in the following sections, meet or exceed the criteria of the REHP plan as specified by Requirement for Operability, 6.3. 1. 1 (3. 12. 1).

5.1 Radiolo ical Environmental Monitorin Pro ram REMP Environmental samples for the REHP are collected in accordance with Table 5-1.

This table provides a detailed outline of the environmental sampling plan including both Requirement for Operability and non Requirement for Operability items by sample type, sample location code, sampling and collection frequency, and type and frequency of analysis of samples collected within exposure pathway. Deviations from 'the sampling frequency detailed in Table 5-1 may occur due to circumstances such as hazardous conditions, malfunction of automatic sampling equipment, seasonal unavailability, or other legitimate reasons. When sample media is unobtainable due to equipment malfunction, 94

CONTROLLED COPY AMENDMENT NO. 16 DECEMBER 1993 special actions per program instruction shall be taken to ensure that corrective action is implemented prior to the end of the next sampling period.

In some cases, alternate sample collection may be substituted for the missing specimen. All deviations from the sampling plan Requirement for Operability items detailed in the sampling plan, Table 5-1, shall be documented and reported in the Annual Radiological Environmental Operating Report in accordance with PPM 1. 10.2, "Routine or Periodic Reports Required by Regulatory Agencies", Regulatory Guide 4.8 and BTP.

In the event that it becomes impossible or impractical to continue sampling a media of choi.ce at currently established location(s) or time, an evaluation shall be made to determine a suitable alternative media and/or location to provide appropriate exposure pathway evaluations. The evaluation and any substitution made shall be implemented in the sampling program within 30 days of identification of the problem. All changes implemented in the sampling program due to unavailability of samples shall be fully documented in the next Radioactive Effluent Release Report and ODCM per PPM 1.10.1, "Reportable Events and Occurrences Required by Regulatory Agencies". Revised sampling plan table(s) and figure(s) reflecting the new locations and/or media shall be included with the documentation.

WNP-2 sampling stations are described in Table 5-2. Each station is identified by an assigned number or alphanumeric designation, meteorological sector (16 different, 22-1/2'ompass sections) in which the station is located, and radial distance from WNP-2 containment as estimated from map positions. Also included in Table 5-2 is information identifying the type(s) of samples collected at each station and whether or not the specific sample type satisfies a Requirement for Operability criteria. Figures 5-1 and 5-2 depict the geographical locations of each of the sample stations listed in Table 5-2.

5.2 Land Use Census A Land Use Census shall be conducted in accordance with the requirements of Requirement for Operability 6.3.2. 1 (3. 12.2). It shall identify within.,a distance of 8 km (5 miles) in each of the 16 meteorological sectors, the 95

AHENDHENT 'NO. 23 SEPTEHBER 1995 location of the nearest milk animal, the nearest residence and the nearest garden of greater than 50m (500 ft ) producing broad leaf vegetation.. Field activities pertaining to the Land Use Census will be initiated during the growing season and completed no later than September 30 each year. The information obtained during the field survey is used along with other demographic data to assess population changes in the unrestricted area that might require modifications in the sampling plan to ensure adequate evaluation of dose or dose commitment.

The results of the Land Use Census will be submitted no later than October 31 of each year for evaluation of maximum individual doses or dose commitment.

All changes, such as a location yielding a greater estimated dose or dose commitment or different location with a 20 percent greater estimated dose or dose commitment than a currently sampled location, will be reported in the next Radioactive Effluent Release Report in accordance with PPH 1.10.2 and Requirement for Operability 6.3.2. 1 (3. 12.2). The REHP plan, ODCH, will be changed to reflect new sampling location(s). The new sampling location(s) will be added to the REHP within 30 days.

The best available census information, whether obtained by aerial survey, door-to-door survey, or consultation with local authorities, shall be used to complete the Land Use Census and the census results shall be reported in the Annual Radiological Environmental Operating Report, in accordance with PPH

1. 10.2 and Technical Specification requirements.

5.3 Laborator Intercom arison Pro ra Analysis of,REHP samples is contracted to a provider of radiological analytical services. By contract, this analytical service vendor is required to conduct all activities in accordance with Regulatory Guides 4. 1, 4.8, and

4. 15 and to include in each quarterly report, actions pertinent to their participation in the Interlaboratory Comparison Program. A precontract award survey and periodic audit at the contractor's facility ensure that the contractor is participating in the Crosscheck Program, as reported.

96

AMENDMENT'NO. 23 SEPTEMBER 1995 The results of the contractor's analysis of Crosscheck samples shall be l

included in the Annual Radiological Environmental Operating Report in accordance with PPM 1.10.2 and Requirement for Operability 6.3.3. 1 (3. 12.3).

Besides the vendor's required participation in the Interlaboratory Comparison Program, the Department of Health (DOH) of the State of Washington over sees an analytical program for the Energy Facility Site Evaluation Council (EFSEC) to provide an independent test of WNP-2 REHP sample analyses. The WNP-2/DOH split samples are analyzed by Washington State's Office of Public Health Laboratories and Epidemiology, Environmental Radiation Laboratory (ERL). The results of the ERL analysis and Interlaboratory Comparison Program data are included in an annual report, "Environmental Radiation Program, Environmental Health Surveillance, State of Washington" and is available for comparison with the WNP-2 data.

The Supply System participates in the International Intercomparison of.

Environmental Dosimeter Program. Results of this'intercomparison program are reported in the REHP Annual Report, when available.

5.4 Re ortin Re uirements WNP-2 radiological environmental monitoring program activities are presented annually per PPH 1.10.2 in the Annual Radiological Environmental Operating Report (AREOR). The approved report .is submitted to the Administrator, Region IV Office of Inspection and Enforcement, with copies to the Director, Office of Nuclear Reactor Regulation, and the State of Washington Energy Facility Site Evaluation Council (EFSEC) and Radiation Control Section, DOH, by May I of each year for program activities conducted the previous calendar year. The period of the first operational report begins with the date of initial criticality.

The annual report is to include the following types of information: a tabulated summary; interpretations and analyses of trends for results of radiological environmental surveillance activities for the report period, including comparisons with operational controls, pr eoperational studies, and previous environmental surveillance reports as appropriate; an assessment of 97

AMENDMENT NO. 23 SEPTEMBER 1995 the observed impacts of plant operation on the environment; a brief description of the radiological environmental monitoring program; maps representing sampling station locations, keyed to tables of distance and direction from reactor containment; results of the Land Use Census; and the results of analytical laboratory participation in the Interlaboratory Comparison Program. The tabulated summary shall be presented in a format represented in Table 5-3. A supplementary. report is required if all analytical results are not available for inclusion in the annual report within the specified time frame. The missing data shall be submitted as soon as possible upon receipt of the results. Along with the missing data, the supplementary report shall include an explanation as to the cause for the delay in completion of the analysis within the report period.

A nonroutine radiological environmental operating report is required to be submitted within 30 days from the end of any quarter in which a confirmed measured radionuclide concentration in an environmental sample averaged over the quarter sampling period exceeds a reporting level. Table 5-4 specifies the reporting level (RL) for most radionuclides of environmental importance due to potential impact from plant op'erations. When more than one of the nuclides listed in Table 5-4 is detected in a sample, the reporting level is considered to be exceeded and a nonroutine report required if the following conditions are satisfied:

Concentration I Concentration 2 Reporting Level (I) Reporting Level (2)

For radionuclides other than those listed in Table 5-4, the reporting level is considered to have been exceeded if the potential annual dose to an individual is greater than or equal to the design objective doses of Appendix I, 10 CFR 50. When a nonroutine report on an unlisted (Table 5-4) radionuclide must be issued, it shall include an evaluation of any release conditions, environmental factors, or other aspects necessary to explain the anomalous sample results.

98

g0gyp0gLpp q0py AMENDMENT NO. 9 When it can be demonstrated that the anomalous sample result(s) exceeding reporting levels is not the result of plant effluents, a nonroutine report does not have to be submitted. A full discussion of the sample result and subsequent evaluation or investigation of the anomolous result will be included in the Annual Radiological Environmental Operational Report.

'Gamma isotopic means identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents of the facility.

'TLD refers to thermoluminescent dosimeter. For purposes of WNP-2 REHP, a TLD is a phosphor card (32mm x 45mm x 0.5mm) with eight individual read-out areas (four main dosimeter areas and four back-up dosimeter areas) in each badge case. TLDs used in REHP meet the requirements of Regulatory Guide 4.13 (ANSI N545-1975), except for specified energy-dependence response. Correction factors are available for energy ranges with response outside of the specified tolerances. TLD stations 1S-16S and 61 are special interest stations and are not included amongst the 34 routine TLD stations required by Requirement for Operability, Table 7.3. 1. 1-1 (3. 12-1).

A

'Composite samples will be collected with equipment which is capable of collecting an aliquot at time 0z intervals which are short relative to the compositing period. A composite sample is also one in which the quantity (aliquot) of liquid sampled is proportional to the quantity of flowing liquid and in which the method of sampling employed results in a specimen that is representative of the liquid flow.

'Station 26, WNP-2 makeup water intake from the Columbia River, satisfies the Requirement for Operability criteria for upstream surface water and drinking water control samples. The discharge water (Station 27) samples are used to fulfill the Requirement for Operability criteria for a downstream sample. a However, they provide very conservative estimates of downstream concentrations. Drinking water samples are A not routinely analyzed for 1-131 from two week composite, but I-131 analysis will be performed when the calculated dose for the consumption of water is greater than 1 mrem per year to the maximum organ. When the 0

gross beta result in drinking water is greater than ten times the mean of the previous month's data for the -C control location or greater than 8 pCi/liter, Sr-90 analysis shall be performed.

Hilk samples will be obtained from farms or individual milk animals which are located in sectors with high calculated annual average ground-level D/gs and high dose potential. There are no milk animals located within 5 km of WNP-2. If cesium-134 or cesium-137 is measured in an individual milk sample in excess of 30 pCi/1, then strontium-90 analysis shall be performed.

'There are no commercially important species in the Hanford reach of the Columbia River. Host recreationally important species in the area are anadromous, primarily salminoids. Three species will normally be collected by electroshock technique in the vicinity of the plant discharge (Station 30). If foal C7 electroshocking produces insufficient fish samples, anadromous species may be obtained from Ringold Fish 2 M C: Pl Hatchery (Station 39). Control samples are normally collected from the Snake River, in the vicinity of Ice Harbor Dam (salminoids may be obtained through the National Harine Fisheries Service at Lower Granite Dam). CA Three species (same ones obtained from the Columbia River) will be collected from the control location. If Cl any of the analytical results of the Columb'ia River fish samples are significantly higher than the results lD of the Snake River samples or the results of previous fish samples, sampling will be conducted semiannually..

This limitation provides additional assurance that the levels of radioactive materials in bodies of water in UNRESTRICTED AREAS will result in exposures within (1) the Section II.A design objectives of Appendix I, 10 CFR Part 50, to a HEHBER OF THE PUBLIC and (2) the limits of 10 CFR 20.106(e) to the population. The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-135 is the con-trolling radioisotope and its HPC in air (submersion) was converted to an equivalent concentration in water using the methods described in International Commission on Radiological Protection (ICRP) Publication 2.

This Requirement for Operability applies to the release of radioactive materials in liquid effluents from all reactor units at the site.

The required detection capabilities for radioactive materials in liquid waste samples are tabulated in terms of the lower limits of detection (LLDs).

Detailed discussion of the LLD, and other detection limits can be found in HASL Procedures Manual, ~ASL-300 (revised annually), Corrie, L. A., "Limits for gualitative Detection and guantitative Determination - Application to Udl I Ity,"6 1. I ~. I -96))99), dll t Il,d.d.,

B6.2.1.2 3 4.11.1.2 DOS This Requirement for Operability is provided to implement the requirements of Sections II.A, III.A, and IV.A of Appendix I, 10 CFR Part 50. The Require-ment for Operability implements the guides set forth in Section II.A of Appendix I. The COHPENSATORY HEASURES statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in liquid effluents to UNRESTRICTED AREAS will be kept "as low as is reason-ably achievable." Also, for fresh water sites with drinking water supplies that can be potentially affected by plant operations, there is reasonable assurance that the operation of the facility will not result in radionuclide concentrations in the finished drinking water that are in excess of the requirements of 40 CFR Part 141. The dose calculation methodology and parameters in the ODCH implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data, such that the actual exposure of a HEHBER OF THE PUBLIC through appropriate pathways is unlikely to be substantially underestimated.

This Requirement for Operability applies to the release of radioactive materials in liquid effluents from each reactor unit at the site.

B6.2.1.3 (3/4. 11. 1.3) LI UID RADWASTE TREATMENT SYSTEM The OPERABILITY of the liquid radwaste treatment system ensures that this system will be available for use whenever liquid effluents require treatment prior to release to the environment. The requirement that the appropriate portions of this system be used, when specified, provides assurance that the releases of radioactive materials in liquid effluent will be kept "as low as is reasonably achievable." This Requirement for Operability implements the requirements of 10 CFR 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50 and the design objective given in Section II.D of Appendix I to 10 CFR Part 50. The specified limits governing the use of appropriate portions of the liquid radwaste treatment system were specified as a suitable fraction of the dose design objectives set forth in Section II.A of Appendix I, 10 CFR Part 50, for liquid effluents.

66.2.2.1 )t3/4.11.2.1) ~DOS RATE This Requirement for Operability is provided to ensure that the dose at any time at and beyond the SITE BOUNDARY from gaseous effluents from all units on the site will be within the annual dose limits of 10 CFR Part 20 to UNRESTRICTED AREAS. The annual dose limits are the doses associated with the concentrations of 10 CFR Part 20, Appendix B, Table II, Column l. These limits provide reasonable assurance that radioactive material discharged in gaseous effluents will not result in the exposure of a MEMBER OF THE PUBLIC in an UNRESTRICTED AREA, either within or outside the SITE BOUNDARY, to annual average concentrations exceeding the limits specified in Appendix B, Table II of 10 CFR Part 20 (10 CFR 20. 106(b)). For MEMBERS OF THE PUBLIC who may at times be within the SITE BOUNDARY, the occupancy of that MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for any increase in the atmospheric'iffusion factor above that for the SITE BOUNDARY. Examples of calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors, is provided in the ODCH. The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a HEHBER OF THE PUBLIC at or beyond the SITE BOUNDARY to less than or equal to 500 mrems/year to the total body or to less than or equal to 3000 mrems/year to the skin. These release rate limits also restrict, at all times, the corresponding thyroid dose rate above background to a child via the inhalation pathway to less than or equal to 1500 mrems/year.

CONTROLLED COPY AMENDMENT NO. 10 JANUARY 1992 B6.2.2. 1 (3/4. 11.2. 1) DOSE RATE Continued This Requirement for Operability applies to the release of radioactive materials in gaseous effluents from all reactor units at the site.

The required detection capabilities for radioactive materials in gaseous waste samples are tabulated in terms of the lower limits of detection (LLDs).

Detailed discussion of the LLD and other detection limits can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L. A., "Limits for Qualitative Detection and Quantitative Determination - Application to Radio-chemistry," Anal. Chem. 40, 586-93 (1968), and Hartwell, J. K. , "Detection Limits for Radioanalytical Counting Techniques," Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

B6.2.2.2 (3/4. 11.2.2) DOSE - NOBLE GASES This Requirement for Operability is provided to implement the requirements of Sections II.B, III.A, and IV.A of Appendix I, 10 CFR Part 50. The Require-ment for Operability implements the guides set forth in Section II.B of Appendix I. The COMPENSATORY MEASURES statements provide the required operating flexibility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive material in gaseous effluents to UNRESTRICTED AREAS will be kept "as low as is reason-ably achievable." The PERIODIC TESTS AND INSPECTIONS requirements implement the requirements in Section III.A of Appendix I that conformance with the guides of Appendix I be shown by calculational procedures based on models and data such that the actual exposure of a MEMBER OF THE PUBLIC through appro-priate pathways is unlikely to be sub'stantially underestimated. The dose calculation methodology and parameters established in the ODCH for calculating the doses due to the actual release rates of radioactive noble gases in gaseous effluents are consistent with the methodology provided in Regulatory Guide 1. 109, "Calculation of Annual Doses to Han from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1. 111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water Cooled Reactors," Revision 1, July 1977.

The ODCH equations provided for determining the air doses at and beyond the SITE BOUNDARY are based upon the historical average atmospheric conditions.

This Requirement for Operability applies to the release of radioactive materials in gaseous effluents from each reactor unit at the site.

B6.2.2.3 (3/4.11.2.3) DOSE - IODINE- 131 IODINE- 133 TRITIUM AND RADIONUCLIDES IN PARTICULATE FORM This Requirement for Operability is provided to implement the requirements of Sections II.C, III.A, and IV.A of Appendix I, 10 CFR Part 50. The Require-ment for Operability are the guides set forth in Section II.C of Appendix I.

The COMPENSATORY MEASURES statements provide the required operating flexi-bility and at the same time implement the guides set forth in Section IV.A of Appendix I to assure that the releases of radioactive materials in gaseous effluents to UNRESTRICTED AREAS will be kept "as low as is reasonably achievable."

The ODCH calculational methodology and parameters for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in Regulatory Guide 1. 109, "Calculation of Annual Doses to Han from Routine Releases of Reactor Effluents for the Purpose of Evalu'ating Compliance with 10 CFR Part 50, Appendix I,"

Revision 1, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Mater-Cooled Reactors," Revision 1, July 1977. These equations also provide for determining the actual doses based upon the historical average atmospheric conditions or concurrent meteorology. The release rate specifications for iodine-131, iodine-133, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent upon the existing radionuclide pathways to man, in the areas at and beyond the SITE BOUNDARY. The pathways that were examined in the development of these calculations were: (1) individual inhalation of airborne radionuclides, (2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, (3) deposition onto grassy areas where milk animals and meat-producing animals graze with consumption of the milk and meat by man, and (4) deposition on the ground with subsequent exposure of man.

The requirement that the appropriate portions of these systems be used, when specified, provides reasonable assurance that the releases of radioactive materials in gaseous effluents will be kept "as low as is reason-ably achievable." This Requirement for Operability implements the require-ments of 10 CFR 50.36a, General Design Criterion 60 of Appendix A to 10 CFR Part 50, and the design objectives given in Section II.D of Appendix I to 10 CFR Part 50.

CGNTROLLED COPY AMENDMENT NO. 9 JANUARY 1992 B6. 2 RADIOACTIV EFF VENTS BASES B6.2.4.1 (3/4.11.4) ~TOTAL DOS This Requirement for Operability is provided to meet the dose limitations of 40 CFR Part 190 that have been incorporated into 10 CFR Part 20 by 46 FR 18525. The Requirement for Operability requires the preparation and submittal of a Special Report whenever the calculated doses from plant generated radioactive effluents and direct radiation exceed 25 mrems to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrems. For sites containing up to four reactors, it is highly unlikely that the resultant dose to a HEHBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the individual reactors remain within twice the dose design objectives of Appendix I, and if direct radiatiop doses from the reactor units and outside storage tanks are kept small. The Special Report will describe a course of action that should result in the limitation of the annual dose to a HEHBER OF THE PUBLIC to within the 40 CFR Part 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources is negligible with the exception that dose contributions from other nuclear fuel cycle facilities at the same site or within a radius of 8 km must be considered. If the dose to any MEMBER OF THE PUBLIC is estimated to exceed the requirements of 40 CFR Part 190, the Special Report with a request for a variance (provided the release conditions resulting in violation of 40 CFR Part 190 have not already been corrected), in accordance with the provisions of 40 CFR 190.11 and 10 CFR 20.405c, is considered to be a timely request and fulfills the requirements of 40 CFR Part 190 until NRC staff action is com-pleted. The variance only relates to the limits of 40 CFR Part 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR Part 20, as addressed in Requirement for Operability 6.2.1.1 (3. 11. 1.)1 and 6.2.2.1 (3.11.2.1). An individual is not considered a HEHBER OF THE PUBLIC during any period in which he/she is engaged in carrying out any operation that is part of the nuclear fuel cycle.

This monitoring program implementsSection IV.B.2 of Appendix I to 10 CFR Part 50 and thereby supplements the radiological effluent monitoring program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways. Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environ-mental Monitoring. The initially specified monitoring program will be effec-tive for at least the first 3 years of commercial operation. Following this period, program changes may be initiated on operational experience.

The required detection capabilities for environmental sample analyses are tabulated in terms of the lower limits of detection (LLDs}. The LLDs required by Table 6.3.1. 1. 1-1 (4. 12-1) are considered optimum for routine environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an g ~r ~or (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.

Detailed discussion on the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L. A., "Limits for gualitative ddl 6 ltd."II I. I ~ .66-Detection and quantitative Determination - Application to II66t,dd t. Il,l.d.,

B6.3.2.1 (3/4.12.2) LAND USE CENSUS This Requirement for Operability is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the radiological environmental monitoring program are made the results of this census. The best information from the door-to-door if requir'ed by survey, from aerial survey or from consulting wi,th local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10 CFR Part 50. Restricting the census to gardens of greater than 50 m'rovides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to produce the quantity (26 kg/year) of leafy vegetables assumed in Regulatory Guide 1. 109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: (1) 20/m of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage}, and (2} a vegetation yield of 2 kg/m'.

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 ID EFFLVENTS 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 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 average flow rate of the Columbia River during January through December 1994 was 9.5E+04 cubic feet per second.

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.

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 abnormal releases.

A EO EFFLUENT 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 in a marinelli beaker and analyzing them using gamma spectroscopy. Tritium is analyzed 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 0.577 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 ODCM limits are listed on Table 3-0.

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.

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 less than 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.

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

The Main Plant Vent Release Monitor was out of service for greater than 30 days.

Compensatory Measures in accordance with ODCM 6.1.2.1-1.3a, action 110 were initiated and continued until the detector was returned to service. A loss of vacuum on the HPGe detector caused the instrument to be inoperable. This equipment failure occurred on May 14, 1994. At that time the plant had begun its annual refueling outage. The detector is located on the refuel floor, and is not accessible during refueling operations, Repairs began after refueling activities were complete, and the instrument area was appropriately prepared for work. The exact nature of the equipment failure was not known when repairs began, which resulted in an extended repair and testing period. The instrument was returned to service on September 23, 1994. (Ref. PER 294-0563)

The Turbine Building Ventilation Exhaust Monitor was out of service for greater than 30 days. Compensatory Measures in accordance with ODCM 6.1.2.1-1.4a, b, c, actions 110 and 112 were initiated and continued until the detector was returned to service. A modification to the size of the building exhaust fan motors resulted in an increase in the maximum exhaust flow rate for the building from 320,000 cfm to 360,000 cfm. This increase in maximum flow rate required a modification in the sampling system to retain its ability to collect an isokinetic sample. The instrument was removed from service on May 6, 1994 and returned to service on July 24, 1994.

(Ref. PER 294-0702)

An independent review of our ODCM instrument surveillance program revealed a weakness in the method of performing a source check of the Offgas Pre-Treatment radiation monitor. This instrument has no built-in check source. Our method of performing this source check had been to collect a sample of the radioactive stream

'nd verify an appropriate reading. This method did not cause any change in the instrument's reading. We have modified our source check method to include opening of the sample chamber purge line. This produces a significant change in the instrument's reading, and provides a more positive verification of appropriate response to changes in offgas activity. (Ref. PER 294-0875)

A Quality Assurance audit of our radioactive effluents program recommended that we review the gas mixture used for our Main Plant Ventilation Effluent Monitor setpoint calculation. This setpoint can be based on either a normal operational gas mixture, or on a shorter lived gas mixture which is applicable when our offgas treatment system is in the bypass mode. The shorter lived gas mixture results in a lower setpoint. The determination was made to use the lower setpoint as our normal value to avoid the need to change the setpoint if it became necessary to bypass the offgas treatment system.

In the process of performing the new setpoint calculation instrument Setpoint Change Request ¹1235,) an error in the original calculation was discovered. The instrument was declared inoperable, in accordance with ODCM 6.1.2.1.a, and appropriate compensatory measures were initiated in accordance with ODCM 6.1.2.1-1.3a, action 110. The new setpoint was approved and installed in the instrument within twenty-four hours, and returned to service.

At no time during the operation of the Main Plant Ventilation Release Monitor with a non-conservative setpoint did the monitor's reading exceed the lower setpoint value.

This setpoint is an alarm function only, and causes no automatic actions. The setpoint for the Main Plant Ventilation Plenum Monitors, which do cause an automatic isolation of this system, were correct and continuously in service. (Ref. PER 294-0979)

A review of alpha activity published in previous effluent reports has revealed a calculational error in several reporting periods. The conversion factor of 2.83E+04 cm'/ft was omitted from the total alpha activity calculation.

The table below shows the old and corrected value for applicable reporting periods.

These values were reported in Table 3-4 of the applicable reports. This correction to the reported activity was purely calculational, and does not indicate an actual increase in the rate of discharge. These results do not indicate any fuel failure or other mode of alpha activity release.

5.0 METEOR L Y 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 for the. calendar year 1994. Data is archived on a PRIME Computer System through 1994. Data storage is being moved to the IBM LAN in 1995 for storage and processing.

The year 1994 was more moist, warmer and the winds calmer than 1993. Precipitation was near normal for 1994 with the occurrence of fog and haze and blowing dust much less than 1993. There were few arctic outbreaks of cold air. 1994 had normal rainfall in the fall. Snowfall and rain were near normal, In summary, the dispersive environment for WNP-2 for 1994 was near 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 1994.

All significant outages coincided with scheduled and unscheduled power outages at WNP-2. High winds resulted in broken wind propellers with 3 days data loss.

Lightning strikes and thunderstorms were of minor concern and had no significant effect on meteorological tower operations. Backup alternative power was added in 1993 and was used during the outage.

Tables 5-1 through 5-8 list the joint frequency distributions at the 33 ft and the 245 ft levels for 1994 by quarter with 5-9 and 5-10 listing the annual joint frequency distributions for 1994. 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 1994 as the releases were random in time.

Calibrations performed in 1994 produced no values exceeding WNP-2 FSAR meteorological equipment tolerances. Therefore, no corrections have been 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.

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 doses 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 3.5E-05 mrem/yr, thyroid dose of 7.2E-06 mrem/yr and a liver dose value of 4.4E-05 mrem/yr. The population doses at this location showed a total body value of 9.8E-05 person-rem, thyroid dose of 2.1E-05 person-rem and a bone value of 7,4E-05 person-rem.

fh Ph NRG GARPARif 2 d d 2 I d at and beyond the site boundary. Table 6-5 lists the annual 50-mile dose using values obtained from the ALARA annual 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 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 re o "A Mem er f 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 annual 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 maxiinum age group resulted in annual calculated total body dose of 1.3E-03 mrem. The annual thyroid dose was 9.9E-03 mrem and the maximum dose to any other organ was 1.4E-03 mrem. Exposure pathways were ground, vegetable and inhalation. The air dose contribution was as follows; Beta air dose was 1.2E-04 mrad/yr and the Gamma air dose was 1.4E-04 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 2.1E-04 mrem. The annual child age group thyroid dose was 1.6E-03 mrem and the maximum dose to any other organ for the child age group was 3.0E-04 mrem. The annual Beta air dose was 5.6E-05 mrad and the Gamma air dose was 5.0E-05 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 9.8E-05 mrem. The annual thyroid dose was 2. 1E-05 mrem and the maximum dose to any other organ was 7.4E-05 mrem.

The 1994 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 1994 was less than 11 mrem.
