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.This design objective will be kept at all times.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.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

AMENDMENT NO.9 JANUARY 1992 and the fact that most of the dose from the liquid effluent comes from these two pathways.The dose contributions will be calculated for all radionuclides identified in the released effluent.The calculations are based on guidelines provided by NUREG-0133 and the LADTAP II computer code.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, (average, based on operating data is 808 gpm)and is discharged to the Columbia River with a total flow based on MPC;total, and cooling water flushing needs.The radiation monitor has a minimum sensitivity of 10'Ci/cc of Cs-137, and the radiation indicator has a range of seven decades.The radiation monitor is located on the 437'evel of the Radwaste Building, 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 (3.11.1.1):

AMENDMENT NO.11 AUGUST 1992 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.I (3.11.1.1), as discussed in section 2.3.1 of this manual).The trip/alarm setpoint for the liquid radwaste effluent monitor is calculated from the results of the radiochemical analysis of the waste solution.The setpoint will be set into the radwaste monitor just prior to the release of each batch of radioactive liquid.2.5.2 Methodolo for Determinin the Maximum 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 (MPC,)based on 10 CFR 20 limits, From the sample analysis and the HPC values in 10 CFR 20, the HPC, is determined using the following equation.where: HPC, HPC,=g s-i MPC., Total fraction of the Maximum Permissible Concentrations (HPCs)in the liquid effluent waste sample.C;The concentration of each measured radionuclide i obse}ved by the radiochemical analysis of the liquid waste sample (pCi/ml).

dl p I AMENDMENT NO.11 AUGUST 1992 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 HPC, 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 Methodolo for the Determination of Li uid Effluent Monitor Set oint The measured radionuclide concentrations are used to calculate the dilution factor (Fd), which is the ratio of the total discharge flow rates (fw+fb)to the radwaste tank effluent flow rate (fw)that is required to assure that the limiting concentrations of Requirement for Operability 6.2.1.1 (3.11.1.1)are met at the point of discharge.

The dilution factor (Fd)is determined according to: Fd=m I s-i HPC., x Fs (9)where: Fd The dilution factor required for compliance with 10 CFR 20, Appendix B, Table II, Column 2.-C;The concentration of each radionuclide i observed by radiochemical analysis of the liquid waste sample (pCi/ml).10 AMENDMENT NO.9 JANUARY 1992 HPC;The limiting concentration 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.Fs The safety factor;a conservative factor used to compensate for statistical fluctuations and errors in measurements.

For example, a safety factor (Fs)of 1.5 corresponds to a fifty (50)percent (%)variation.

The total number of measured radionuclides i in the liquid batch to be released.The dilution which is required to ensure compliance with Requirement for Operability 6.2.1.1 (3.11.1.I)concentration limits will be set such that discharge rates are: fw+fb Fd<fw and follows that: fw<-fb Fd-1 or (10)(10a)where: fb>fw(Fd-1)(10b)The dilution factor from Equation (9).fw The discharge flow rate from the liquid radwaste tank to the blowdown line-variable from 0 to 190 gpm.fb The cooling tower blowdown flow rate-variable from 0 to 7500 gpm.The liquid effluent radiation monitor response is based on the results of the radiochemical analysis of the waste solution.Therefore the calculation for AMENDMENT NO.9 JANUARY 1992 the radiation monitor's alarm/trip setpoint is: where: SP=C+BKg+K[C+Bkg]'" SP Radiation monitor setpoint (count rate)(Cix E.)represents the count rate from the i~1 radionuclides in the liquid radwaste.C;The concentration of each measured radionuclide i observed by radiochemical analysis of the liquid waste sample (pCi/ml).Same as for Equation (9).E,;The radwaste effluent monitor's response to radionuclide i (count rate per pCi/ml).BKg Background count rate of the radwaste effluent monitor.A constant to compensate for normal expected statistical variations in the liquid effluent radiation monitor count rate to reduce the chance of false alarms/trips; K=3.2.6 Verification of Com liance with 10 CFR 50 A endix I and 10 CFR 20 A endix B Verification of compliance with 10 CFR 50,'ppendix I, and 10 CFR 20, Appen-dix B, limits will be achieved by following WNP-2 Plant Procedures for liquid discharge and the periodic application of the LADTAP II computer code.12

AHENDHENT NO.9 JANUARY 1992 Equation (18)will be used to calculate the curie limit for a temporary radwaste hold-up tank.The total tank concentration will be limited to less than or equal to ten (gl0)curies, excluding tritium and dissolved or entrained gases.Surveillance requirement 4.11.1.4, states that the quantity of radioactive material in the hold-up tanks shall be determined to be within the limit by analyzing a representative sample of the tank's contents at least once per 7 days when radioactive materials are being added to the tank.where: A T fi HPC,.e"" (18)Ag Total allowed activity in tank (curies).A;Activity of radioisotope i (curies).HPC;Haximum permissible concentration of radionuclide i (10 CFR 20, Appendix B, Table II, Column 2).Decay constant (years")radioisotope i.Transit time of ground water from WNP-2 to WNP-1 well (WNP-2 FSAR Section 2.4)=67 years.A,.Fraction of radioisotope fi=gA,.Index for all radioisotopes in tank except tritium and noble gases.Dispersion constant based on hydrological parameters, (2.4E+05 Ci per pCi/cc.)19 AMENDMENT NO.9 JANUARY 1992 The total allowed activity (A,)is based on limiting WNP-1 well water to less than 1 MPC, 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 nearest 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 (CW;)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;).Limiting well concentration to 1 MPC yields;CW,.CT., e"'PC,.CRF.MPCi (19)fFtom Section 2.4 of WNP-2 FSAR)(4 7r L)'" (a a a)'" 2V (20)where: L V o'x t o'y t o'z Migration distance-1 mile.Volume of tank.Dispersion constants.

If the setpoint is exceeded, an alarm will activate in the main control room.The control room operator can then terminate the discharge and mitigate any uncontrolled release of radioactive material.2.9.2 Turbine Buildin Service Water TSW Monitor~~This monitor is located on the 441'evel of the Turbine Building.The readout meter and recorder is located in the main control panel BD-RAD-24.

The flow rate through that monitor is variable, from zero (0)to six (6)gpm with a normal flow of 3-4 gpm.To ensure 10 CFR 20 limits are never exceeded, the alarm setpoint shall be established at 80%or less of the maximum setpoint plus background.

The Turbine Building Sump Water Effluents are not released to the Columbia River.This effluent is discharged to the Storm Drain System which is an open pond by the WNP-2 Warehouse.

The hydrological analysis performed for the WNP-2 FSAR (Section 2.4)determined that the transmit time through the ground water from WNP-2 to the WNP-1 well is 67 years for strontium and 660 years for cesium.In the event the setpoint is exceeded, the sump water will be automatically routed to the radioactive waste system.To prevent the sum of the sump water discharged from the three pumps from exceeding 10 CFR 20 limits, the alarm/setpoint will be established at 80%or less of the maximum setpoint plus background.

AMENDMENT NO.11 AUGUST 1992 3.0 GASEOUS EFFLUENTS DOSE CALCULATIONS 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 ODCN 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 to 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.

3.1 Introduction

WNP-2 gaseous effluents are released on a continuous basis;in addition, batch releases also occur 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.

'k AMENDMENT NO.11 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.

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/gs from XO(DOg.(Note: Desert Sigmas were used in calculating X/g and D/g values, and are listed in Table 3-10 to 3-12).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 of 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/g and D/g values.3.2 Gaseous Effluent Radiation Monitorin S stem 3.2.1 Hain Plant Release Point The Hain Plant Release is instrument monitored for gaseous radioactivity prior to discharge to the environment via the main plant vent release point.Par-ticulates 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 35 k

AMENDMENT NO.9 JANUARY 1992 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 low range beta scintillator, an intermediate range beta scintillator and two ion chamber LOCA monitors.The beta scintil-lators are mounted in thick 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.The intermediate range has a response from 10'10'Ci/cc Xe-133 equivalent, and reads in panel meter units (PMU)with a meter range of 10-10'MU.The readouts and recorder are located in the main control room panel BD-RAD-24.

Power is provided from 125 VDC divisional buses.This monitor has no control function but annunciates in the main 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

~a I AMENDMENT NO.9 JANUARY 1992 analysis.After the particulate and iodine filters, the air sample streams are combined in a manifold prior to being monitored by a beta scintillator.

The beta scintillators, on the 487'evel are mounted in lead shielded chambers.The low range beta scintillator has an approximate response of 80 cpm/pCi/cc to'r-85, and 50 cpm/pCi/cc to Xe-133 and a meter range of.10-10 cpm.The intermediate range has a response from 10-10 pCi/cc Xe-133 equivalent, and reads in panel meter units (PMU)with a meter range of 10-10'MU.The readouts and recorder are located in the main control room panel BD-RAD-24.

Power is provided from 125 VDC divisional buses.This monitor has no control functions but annunciates in the main control room.The alarm will initiate proper action as defined in the WNP-2 plant procedures.

3.2.3 Turbine Buildin Ventilation Exhaust Monitor This monitoring system detects fission and the activation products from the turbine building air which may be present due to leaks from the turbine and other primary components in the building.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 continuously, with one in standby to provide a flow of 260,000 cfm.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.The intermediate range has a response from 10-10'Ci/cc Xe-133 equivalent, and reads in panel meter units (PMU)with a meter range of 10-10'MU.The monitors are on the 525'evel of the radwaste building and the readouts and the recorder are located in the main control room panel BD-RAD-24.

Power is provided from 37 AMENDMENT NO.9 JANUARY 1992 the 125 VDC divisional buses.This monitor has no control functions but annunciates in the main control room.The alarm will initiate proper action as defined in the WNP-2 plant procedures.

Whenever the main condenser steam jet air ejector (evacuation) system is in operation." Prior to placing the gaseous radwaste treatment system in the charcoal bypass mode, the alarm setpoints on the main plant vent release monitor shall be set to account for the increased percentages of short-lived noble gases.Noble gas percentages shall be based either on actual measured values or on primary 55 A,I ANENDHENT NO.11 AUGUST 1992 coolant design base noble gas concentration percentages adjusted for 30-minute decay.Table 3-15 lists the percentage values for 30-minute decay.3.5.1 Pro'ection of Doses The projected doses due to WNP-2 gaseous effluent releases will be determined at least once per 31 days as stated in Requirement for Operability 6.2.2.5 (3.11.2.5).The projected dose when averaged over 31 days is not to exceed 0.3 mrem to any organ in a 31 day period to areas at and beyond the site boundary.Dose projection values will be determined by using a previous 31 day"Gaspar Output" (NRC Computer Code)for the site boundary and/or an area beyond the site boundary.Based on operating data, the projected dose should be adjusted accordingly to compensate for those anticipated changes in operations and/or source term values.3.6 Calculation of Gaseous Effluent Honitor 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 is calculated using a conservative radionuclide mix obtained from the WNP-2 GALE code.Once 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 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.3.6.2.1 Set pints Calculations Based on Whole Bod Dose Limits The fraction (x,.)of the total gaseous radioactivity in each gaseous effluent release path j for each noble gas radionuclide i will be determined by using the following equation: M,, x,,=-" (dimensionless)

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 AMENDMENT NO.9 JANUARY 1992 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 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 computer code, and methodology presented by Equations (10), (ll)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 1 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 (REHP)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.

'3 Pk AMENDMENT NO.9 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.Additional site information is available in the WNP-2 Environmental Report, Operating License Stage.Radiological environmental monitoring activities implemented by PPM 1.11.1"Radiological Environmental Monitoring Program (REHP)Implementation Proce-dure", as detailed in the following sections, meet or exceed the criteria of the REMP plan as specified by Requirement for Operability, 6.3.1.1 (3.12.1).5.1 Radiolo ical Environmental Honitorin Pro ram REHP 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, l N AMENDMENT NO.9 JANUARY 1992 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 choice 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 sub-stitution 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 Semiannual Radioactive Effluent Release Report and ODCH per PPH 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 iden-tified 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 location of the nearest milk animal, the nearest residence and the nearest 95 AMENDMENT NO.9 JANUARY 1992 garden of greater than 150m'500 ft')producing broad leaf vegetation.

Field activities pertaining to the Land Use Census (LUC)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'he 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 Semiannual Radioactive Effluent Report in accordance with PPH 1.10.2 and Requirement for Operability 6.3.2.1 (3.12.2).The REMP plan, ODCM, 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 ram Analysis of REHP samples is contracted to a provider of radiological analyti-cal 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 participa-tion in the Environmental Protection Agency's (EPA)Environmental Radioactivity Laboratory Intercomparison Studies (Crosscheck)

Program.A precontract award survey and annual audit at the contractor's facility ensure.that the contractor is participating in the Crosscheck Program, as reported.96

AMENDMENT NO.10 JANUARY 1992 The results of the contractor's analysis of Crosscheck samples shall be 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 EPA's Crosscheck Program, the Department of Health (DOH)of the State of Washington oversees an analytical program for the Energy Facility Site Evaluation Council (EFSEC)to provide an independent test of WNP-2 REMP 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 State's ERL participates in the EPA Crosscheck Program, as well as other federal participatory analytical quality assurance programs.The results of the ERL analysis and EPA Crosscheck 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 REMP Annual Report, when available.

5.4 Re ortin Re uirements WNP-2 radiological environmental monitoring program activities are presented annually per PPM 1.10.2 in the Annual Radiological Environmental Operating Report (AREOR).The approved report is submitted to the Administrator, Region V 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 1 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, preoperational studies, and previous environmental surveillance reports as appropriate; an assessment of 97 AMfNDHENT NO.9 JANUARY 1992 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 EPA's Crosscheck 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 operations.

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 (1)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 AMENDMENT NO.9 JANUARY 1992 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.99 TABLE 5-1 RADIOLOGICAL ENVIRONHENTAL HONITORING PROGRAH PLAN Sam le T e" Sam le Location Code*Sampling and Collection Fre uenc'ype and Frequency of Anal sis'.AIRBORNE a.Particulates and 1, 4-9A, 21, 23, 40, radioiodine 48 and 57 (5/12)Continuous sampling Weekly collection Particulate:

For purposes of WNP-2 RENP, 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).Composite samples will be collected with equipment which is capable of collecting an aliquot at time 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.However, they provide very conservative estimates of downstream concentrations.

Drinking water samples are 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 gross beta result in drinking water is greater than ten times the mean of the previous month's data for the 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 electroshocking produces insufficient fish samples, anadromous species may be obtained from Ringold Fish 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 Marine Fisheries Service at Lower Granite Dam).Three species (same ones obtained from the Columbia River)will be collected from the control location.If any of the analytical results of the Columbia River fish samples are significantly higher than the results of the Snake River samples or the results of previous fish samples, sampling will be conducted semiannually.

RADIOACTIVE LI UID EFFLUENT MONITORING INSTRUMENTATION The radioactive liquid effluent instrumentation. is provided to monitor and control, as applicable, the releases of radioactive materials in liquid effluents during actual or potential releases of liquid effluents. The alarm/trip setpoints for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCH to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20.The OPERABILITY and use of this instrumentation is consistent with the require-ments of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.The purpose of tank level indicating devices is to assure the detec-tion and control of leaks that if not controlled could potentially result in the transport of radioactive materials to UNRESTRICTED AREAS.B6.1.2 (3/4.3.7.12) RADIOACTIVE GASEOUS EFFLUENT MONITORING INSTRUMENTATION The radioactive gaseous effluent instrumentation is provided to monitor and control, as applicable, the releases of radioactive materials in gaseous effluents during actual or potential releases of gaseous effluents. The alarm/trip setpoints for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the ODCM to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20.This instrumentation also includes provisions for monitoring the concentrations of potentially explosive gas mixtures in the WASTE GAS HOLDUP SYSTEM.The OPERABILITY and use of this instrumentation is consistent with the require-ments of General Design Criteria 60, 63, and 64 of Appendix A to 10 CFR Part 50.169 B6.2 (3/4.11)RADIOACTIVE EFFLUENTS BASES AMENDMENT NO.9 JANUARY 1992 BN.E.I (6/N.ll)~LI I EFFL ENTE B6.2.1.1 (3/4.1.1.1)CONCENTRATION This Requirement for Operability is provided to ensure that the concentration of radioactive materials released in liquid waste effluents to UNRESTRICTED AREAS will be less than the concentration levels specified in 10 CFR Part 20, Appendix B, Table II, Column 2.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 MEMBER 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 b'ased upon the assumption that Xe-135 is the con-trolling radioisotope and its MPC 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, HASL-300 (revised annually), Currie, L.A.,"Limits for gualitative Detection and guantitative Determination -Application to Radiochemistry," 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).B6.2.1.2 3 4.11.1.2 DOSE 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 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 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 ODCM 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 appropriate pathways is unlikely to be substantially underestimated.

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. This Requirement for Operability applies to the release of radioactive mate-rials in liquid effluents from each reactor un'it at the site.86.2.2 (3/4.11.2)GASEOUS EFFLUENTS B6.2.2.1 (3/4.11.2.1)DOSE 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 1.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 diffusion 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 ODCM.The specified release rate limits restrict, at all times, the corresponding gamma and beta dose rates above background to a MEMBER 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. 171 B6.2.2.1 (3/4.11.2.1)DOSE RATE Continued AMENDMENT NO.10 JANUARY 1992 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 gualitative Detection and guantitative 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 substantially 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 methods specified in the Requirement for Operability implement the requirements in Section III.A of Appendix I that 172 AMENDMENT NO.9 JANUARY 1992 B6.2.2.3 (3/4.11.2.3) DOSE-IODINE-131 IODINE-133 TRITIUM AND RADIONUCLIDES IN PARTICULATE FORM Continued 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 appropriate pathways is unlikely to be substantially under-estimated. 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 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.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.This Requirement for Operability applies to the release of radioactive materials in gaseous effluents from each reactor unit at the site.173 B6.2 RADIOACTIVE EFFLUENTS BASES AMENDMENT NO.9 JANUARY 1992 B6:2.2.4 and 6.2.2.5 (3/4.11.2.4 and 3/4.11.2.5)GASEOUS OFFGAS RADWASTE TREATMENT SYSTEM and VENTILATION EXHAUST TREATMENT SYSTEM The OPERABILITY of the GASEOUS OFFGAS RADWASTE TREATMENT SYSTEM and the VENTI-LATION EXHAUST TREATMENT SYSTEM ensures that the systems will be available for use whenever gaseous effluents require treatment prior to release to the environment. 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.The specified limits governing the use of appropriate portions of the systems were specified as a suitable fraction of the dose design objectives set forth in Sections II.B and II.C of Appendix I, 10 CFR Part 50, for gaseous effluents. B6.2.2.6 (3/4.11.2.8) VENTING OR PURGING This Requirement for Operability provides reasonable assurance that releases from drywell purging operations will not exceed the annual dose limits of 10 CFR Part 20 for unrestricted areas.'B6.2.3.1 (3/4.11.3) SOLID RADIOACTIVE WASTE This Requirement for Operability implements the requirements of 10 CFR 50.36a and General Design Criterion 60 of Appendix A to 10 CFR Part 50.The process parameters included in establishing the PROCESS CONTROL PROGRAM may include, but are not limited to, waste type, waste pH, waste/liquid/solidification agent/catalyst ratios, waste oil content, waste principal chemical constit-uents, mixing and curing times.174 B6.2 RADIOACTIVE EFFLUENTS BASES AMENDMENT NO.9 JANUARY 1992 B6.2.4.1 (3/4.11.4)TOTAL DOSE 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 MEMBER 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 radiation 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 MEMBER 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 MEMBER 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.175 AMENDMENT NO.9 JANUARY 1992 B6.3 (3/4.12)RADIOLOGICAL ENVIRONMENTAL MONITORING BASES B6.3.1.1 (3/4.12.1) MONITORING PROGRAM The radiological environmental monitoring program required by this Require-ment for Operability provides representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the highest potential radiation exposures of MEMBERS OF THE PUBLIC resulting from the plant operation. This monitoring program implements Section 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 a griori (before the fact)limit representing the capability of a measurement system and not as an a gosteriori (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 Qualitative Detection and Quantitative Determination -Application to Radiochemistry," 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).B6.3.2.1 (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 if required by the results of this census.The best information from the door-to-door survey, from aerial survey or from consulting with 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%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'.176
