AMENDMENT NO. 6 November 1988 2.0 LI UID EFFLUENT DOSE CALCULATION 2.1 Introduction Liquid radwaste released from HNP-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'ctual 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 efflu-ents 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 consump-tion. 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 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.

Af1ENDtlENT NO. 3 February 1986 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 of 2690 gpm) and is discharged to the Columbia River with a total flow based on ~'IPCi 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 Technical Specification 3.11.1.1:

"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 10-4 pCi/m total activity concentratra-tion for all dissolved or entrained noble gases."

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 will be determined in accordance with Supply System procedure PPt1 12.5.3, Liquid Effluent Discharge Determination.

Liquid effluent discharge is determined and calculated according to PPtl 12.11.1, Radiological Effluent tIonitoring Gaseous and Liquid. The effluent Con<,. = ~

concentration is determined by the following equation:

Cixfw

AMENDMENT NO. 3 February 1986 where:

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

Ci Concentr ation 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 - var iable from 0 to 7500 gpm.

ft = Total discharge flow rate - (ft = fb + fw)

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

g'onC'/MPC' 1 (2) i=1 where:

C'nC. The concentration of radionuclide i in the effluent at the point of discharge into the river.

MPCi Maximum permissible concentration of nuclide i as listed in 10 CFR 20, Appendix B, Table II.

m = Total number of radionuclides in the batch.

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

'AMENDMENT NO. 3 February 1986 The average activity of radionuclide i during the time period of the release is divided by the Plant Discharge Flow/Tank Discharge Flow ratio yielding the concentration at the point of discharge:

Cik x fw (3)

Cik where:

ConC-k Cik

= The concentration of radionuclide i in the effluent at the point of discharge during the release period k

- (>Ci/ml).

Cik = The concentration of radionuclide i in the batch during the release per iod k - (~Ci/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.

ft = 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:

g (ConC,-k/MPC.

i=1 1

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

AHENDHENT NO. 6 November 1988 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 Technical Specification 4.11.1.2 requires that the cumulative dose contribu-tions be determined in accordance with the ODCH at least once per 31 days.

Technical Specification 3.11.1.2 specifies that the dose to a member of the public from radioactive material in liquid effluents released to the unre-stricted area shall be limited to:

< 1.5 mrem/Calendar quarter Total Body and

< 5.0 mrem/Calendar quarter Any Organ.

The cumulative dose for the calendar year shall be limited to:

< 3 mrem. Total Body and

< 10 mrem Any Organ.

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

listed in Table 2-1.

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 Projection of Doses The projected doses due to releases of WNP-2 radwaste liquid effluents will be calculated for each batch, using equation 5. If the sum of the accumulated dose to date for the month and the projected dose for the remainder of the month exceeds the technical specification 3.11.1.3 limits, then the liquid radwaste treatment system shall be used. This is to ensure compliance with Standard Technical Specification 3.11.1.3. This technical specification 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.

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 8, Table II, Column 2, are not exceeded in the effluent at the discharge point (i.e.,

compliance with Standard Technical Specification 3.11.1.1, as discussed in section 2.3.1 of this manual).

AMENDMENT NO. 3 February 1986 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 y for Determinin the Maximum Permissible Concentration (MPC)

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 MPC fraction (MPCf) based on 10 CFR 20 limits. From the sample analysis and the MPC values in 10 CFR 20, the MPCf is determined using the following equation.

m C.

1 MPC (8) i=1 i where:

4 h1PC f Total fraction of the Maximum Permissible Concentra-tions (MPCs) 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).

10

AMENDMENT NO. 3 February 1986 MPC. The 1 imi ting concentrations of the appropri ate 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 MCPf is less than or equal to 0.8, the liquid batch may be released at any radwaste discharge or blowdown rate. If the MPCf 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 y 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 Technical Specification 3. ll.l.l are met at the point of discharge.

The dilution factor (Fd) is determined accor ding to:

x Fs (9)

Where:

The dilution factor required for compliance with 10 CFR 20, Appendix B, Table II, Column 2.

AMENDMENT NO. 3 February 1986 C. The concentration of each radionuclide (i ) observed by radiochemical analysis of the liquid waste sample (yCi/ml).

MPCi The 1 imi ting 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 ('X) variation.

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

The dilution which is required to ensure compliance with Technical Specification 3.11.1.1 concentration limits will be set such that discharge rates are:

< fw + fb (10)

Fd fw and follows that:

fw- fb (loa) or fb ~ fw(Fd-1) (1 ob)

Where:

Fd The dilution factor from equation 9.

12

NENDMENT NO. 3 February 1986 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 the radiation monitor's alarm/trip setpoint is; SP = C + BKg + K [C + Bkg]l/2 Mhere:

SP Radiation monitor setpoint (count rate) i=1 (C; x Efi) represents the count rate from the radionuclides in the liquid radwaste.

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

Same as for equation 9.

Individual and population doses based on Richland parameters are calculated for all exposure pathways.

Only the population downstream of the WNP-2 site is affected by the liquid effluents released. There is no significant commercial fish harvest in the 50-mile radius region around WNP-2. Sportfish harvest is estimated at 14,000 kg/year.

For irrigated foods exposure pathways, it can be assumed that production with-in the 50-mile radius region around WNP-2 is sufficient to satisfy consumption requirements.

Other relevant parameters relating to the irrigated foods pathways are defined as follows:

Technical Specification 3.11.1.4 states the quantity of radioactive material contained in any outside temporary tanks shall be limited to the limits calculated in the ODCM such that a complete release of the tank contents would not result in a concentration at the nearest offsite potable water supply that would exceed the limits specified in 10 CFR Part 20 Appendix B, Table II.

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 ((10) 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.

AMENDMENT NO. 3 February 1986 The total allowed activity (AT) is based on limiting WNP-1 well water to less than 1 NPC.1 of the entire liquid content of the tank spilled to ground and then migrated via ground water to the WHP-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 conser vatively based on all liquid radwaste in the tank instantaneously reaching the water table.

The hydrological analysis performed for the WHP-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.) i is simply the con-centration in the tank (CT.) adjusted for radioactive decay during transit 1

~

As mentioned in Section 2.2 of this manual, all liquid radwaste effluent is discharged through a four-inch line that is monitored by an off-line sodium iodide radiation monitor. This monitor is located on the of the Radwaste Building. All WNP-2 radwaste liquid effluent is 437'evel discharged to the Columbia River through the 36-inch Cooling Mater Blowdown line. In addition to the liquid effluent discharge monitor there are three liquid streams that are normally non-radioactive but have a finite possibility of having radioactive material injected into them.

These liquid streams are:

o Standby Service Mater (SW) o Turbine Building Ser vice Mater (TSW) o Turbine Building Sump Water (FD) 22

AMENDMENT NO. 3 February 1986 To prevent any discharges of radioactive liquid from these streams, radiation monitoring systems have been installed to detect any increase above the normal background concentration of radioactive material.

Alarm/setpoints are established to prevent any release of radioactive material in concentrations greater than 10CFR20 limits. The maximum radiation detector setpoint calculation for the three systems is based on i concentration of Cs-137 which is 2. OE-05 pCi/ml; The follow-ing equation is used to calculate the maximum setpoint:

Setpoint max. = (2.0E-05 pCi/ml) (CF) (25)

(in cpm or cps) where:

2.0E-05 pCi/ml = MPC limit for Cs-137 CF = Monitor calibration factor - in cpm/ pCi/ml or cps/ pCi/ml 2.9.1 Standby Service Water (SW) Monitor - The Standby Service Water Monitors (SW) are located on the 522'evel of the Reactor Building.

The meter is located in the main control room on panel P-604.

The flow rate through the monitor is variable, from zero (0) to two (2) gpm with a normal flow of 1.0-.1.5 gpm.

To ensure 10CFR20 limits are never exceeded, the alarm setpoint shall be established at 80% or less of the maximum setpoint plus background.

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.

AMENDMENT NO. 2 February 1985 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 10CFR20 limits are never exceeded, the alarm setpoint shall be established at 80% or less of the maximum setpoint plus background.

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.

2.9.3 Turbine Buildin Sum s Water (FD) Monitor - There are three detec-tors to measure the activity of each of the three non-radioactive sumps. The monitors are located on the 441'evel of the Turbine Building. The readout meters and recorder are located in the Rad-waste Control Room Panel BD-RAD-41.

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.

AMENDMENT NO. 2 February 1985 To prevent the sum of the sump water discharged from the three pumps from exceeding 10CFR20 limits, the alarm/setpoint will be estab-lished at 80% or less of the maximum setpoint plus background.

3.0 GASEOUS EFFLUENTS DOSE CALCULATIONS 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 instanta-neous technical specification requirement at the site boundary.

Figure 3-1 delineates the WNP-2 Site boundary. There are several low occupancy unrestricted locations within the site boundary. These locations, with the exception of the WNP-2 visitor center, are not continuously controlled by the Supply System. The special 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 activ-ities directly in support of WNP-2.

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

5. WNP-1 - occupied 2080 hrs/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.

33

AHENDHENT NO. 6 November 1988 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 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 high- est X/Q and D/Q values.

3.2 Gaseous Effluent Radiation Honitorin 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.

Particulates and iodine activity are accumulated in filters which will be changed and analyzed as per Technical Specification 4.11.2.1.2 and Table 4.11.2. The effluent is supplied from: the gland seal 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 98,000 CFH 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 scinti llator, an intermediate range beta scintillator and two ion chamber LOCA monitors. The beta scinti llators 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 34

5 in panel meter units (PHU)

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 Honitor The radwaste building ventilation exhaust monitoring system monitors the radio-activity 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 H20 to the environment.

Particulate and iodine air sample filters are changed weekly for laboratory 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 scinti llators, 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 Kr-85, and 50 cpm/pCi/cc to Xe-133 and a meter range of 6 10 3 10-10 cpm. The intermediate range has a response from 10 pCi/cc Xe -133 equivalent, and reads in panel meter units (PHU) with a meter range of 10 -10 PHU. 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.

AMENDMENT NO. 6 November 1988 3.2.3 Turbine Bui ldin 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 centri-fugal 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 scinti llator 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

-2 3 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 PMU. 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 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 NNP-2 plant procedures.

Annual doses within the site boundary have been determined for several loca-tions using the NRC GASPAR computer code and source term data from Table 11.3-7 of the FSAR. These values are listed in Tables 3-16 and 3-17. Of the locations listed within the site boundary, only two, the DOE Train and MNP-2 Visitor Center are considered as being occupied by a "Member of the Public". Annual doses to the maximum exposed "t1ember of the Public" shall be determined for an individual at the WNP-2 Visitor Center based on occupancy of 8 hours per year due to it being the higher of the two locations. 3.5 Com liance with Standard Technical S ecification 3.11.2.4 Standard Technical Specification 3.11.2.4 states:

AMENDMENT NO. 5 April 1988 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 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 Technical Specification 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 Monitor Alarm Set pints 3.6.1 Introduction The following procedure 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 5<a

ANENDNENT NO. 6 November 1988 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 NNP-2 GALE code. Once the plant is operating and sufficient measur-able 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 technical specifications 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 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 technical specifica- tion. Both skin dose and whole body setpoints wi 11 be calculated and the lower limit will be used. 3.6.2.1 Set pints Calculations Based on Nhole Bod Dose Limits The fraction ( " i) 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: N. ~ ij (dimensionless) (22) NT. where: N.. = individual concentration oF radionuclide i in the lj The measured gaseous effluent release path j (pCi/cc). 55

i AMENDMENT NO. 3 February 1986 4.0 COMPLIANCE WITH 40 CFR 190 4.1 Technical S ecification Re uirement Technical Specification 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 Cycle 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. 91

AMENDMENT NO. 4 August 1986 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 Technical Specification 3. 11.1.2a, 3. 11.1.2b, 3.11.2.2a, 3.11.2;2b; 3.11.2.3a,'r 3.11.2.3b. Direct radiation measurements will also be made to determine if the limits of Specification 3. 11.4 have been exceeded. 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. 9la

AMENDMENT NO. 1 May 1984 5.0 RADIOLOGICAL ENVIRONMENTAL.MONITORING Radiological environm ntal monitoring is intended to supplement radiological effluent monitoring by verifying that measur able 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. The WNP-2 REMP 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. 92

AMENDMENT NO. 3 February 1986 Radiological environmental monitoring activities implemented by PPM 1.11.1 "Radiological Environmental Monitoring Program (REMP) Implementation Proce-dure", as detailed in the following sections, meet or exceed the criteria of the REMP plan as specified by Plant Technical Specifications, 3/4.12. 5.1 Radiolo ical Environmental Monitoring Program (REMP) Environmental samples for the REMP are collected in accordance with Table 5-1. This table provides a detailed outline of the environmental sampl'ing plan including both Technical Specification and non Technical Specification items by sample type, sample location code, sampling and collection frequency, and type and frequency of analysis of samples collected within exposure path-way. 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, 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 speci-men. All deviations from the sampling plan Technical Specification items detailed in Table 5-1 shall be documented and reported in the Annual Radio-logical 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 pro-gram due to unavailability of samples shall be fully documented in the next Semiannual 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. 93

AMENDMENT NO. 3 February 1986 WNP-2 sampling stations are described in Table 5-2. Each station is identi-fied by an as'signed number or alphanumeric designation, meteorological sector (16 different, 22-1/2 compass 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 col-lected at each station and whether or not the specific sample type satisfies a Technical Specification 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 Plant Technical Specifications. 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 the sampling plan to ensure adequate evaluation of dose committment. More specific data within each of the 16 meteorological sectors, such as distance to nearest resident, 2 nearest milk animal, and nearest garden greater than 50m (500 ft2

                                                                     ) in size producing broad leaf vegetation shall be identified to support recalcula-tion of maximum individual dose estimates. Site-specific considerations such as the Department of Energy's Hanford Reservation Site Boundary, within which WNP-2  is located,  may require that specific information be collected beyond a 5-mile (8 km) radius in certain meteorological sectors to adequately identify pertinent data.

The results of the land use census will be submitted no later than October 31 of each year for evaluation of individual and population doses.

AMENDMENT NO. 4 August 1986 will d be reported in the next Semiannual Radiological Effluent Report in accor-dance with PPM 1.10.2 and Technical Specification.

The REMP plan, ODCM, will be changed to r'eflect new sampling locations. 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 Survey and the results reported in the Annual Radiologi-cal Environmental Operating Report in accordance with PPM 1.10.2 and Technical Specification requirements. 5.3 Laboratory Intercom arison Pro ram Analysis of REMP samples is contracted to a provider of radiological analyti-cal services. By contract, this analytical service vendor is required to con-duct 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 Radioactiv-ity 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. 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 Technical Specification. Besides the vendor's required participation in the EPA's Crosscheck Program, the Department of Social and Health Services (DSHS) 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/DSHS 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

AMENDMENT NO. 4 August 1986 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 (1) 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 indi-vidual is greater than or equal to the design objective doses of Appendix I, 10 CFR 50.'hen 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. When it can be demonstrated that the anomolous 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. 97

TABLE 5-1 (contd.) C) 4TLD refers to thermoluminescent dosimeter. For purposes of WNP-2 REMP, a TLD is a phosphor card CO ( 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 REMP meet the requirements of Regulatory Guide 4.13 I CO R Ch UJ I (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 are special interest bJ required by Plant Technical Specifi-CY M CL stations and are not included amongst the 34 routine TLD stations cation, Table 3.12-1. 5Composite samples will be collected with equipment which is capable of collecting an aliquot at time intervals which are short relative to the compositing period. 6Station 26, WNP-2 makeup water intake from the Columbia River, satisfies the Technical Specifica-tion criteria for upstream surface water and drinking water control samples. The discharge water (Station

27) samples are used to fulfill the Technical Specification criteria for a downstream sample. However, they provide very conservative estimates of downstream concentrations. Drinking water samples are not routinely analyzed for I-131 from two week composite. 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.

7Milk 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 should be performed. 8There are no commercially important species in the Hanford reach of the Columbia River. Most recreationally important species in the area are anadromous, primarily salminoids. Four fish specimen 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 in the vicinity of Ice Harbor Dam (salminoids may be obtained through the National Marine Fisheries Service at Lower Granite Dam). Garden produce will routinely be obtained from farms or gardens using Columbia River water for irrigation. One sample of a root crop, leafy vegetable, and a fruit should be collected each sample period if available. The variety of the produce sample will be dependent on seasonal availability. 10Soil samples are collected to satisfy the requirements of the Site Certification Agreement (SCA), WNP-2.

AMENDMENT NO. 3 February 1986 6.0 SEMI-ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT Routine Radioactive Effluent Release Reports covering the operation of WNP-2 during the previous 6 months of operation are submitted within 60 days after January 1 and July 1 of each year. These reports shall include a summary of the quantities of radioactive liquid and gaseous effluents released from the unit (WNP-2). Reports shall include each class of soild waste (as defined by 10 CFR 61) shipped offsite during the reporting period with the following information; container volume, total curie quantity, principal radionuclides, source of waste and processing employed, container type, and solidification agent or absorbent. The Radioactive Effluent Release Reports shall include a list and description of unplanned releases from the site to unrestricted areas of radioactive materials in gaseous and liquid made during the repor ting period. The Radioactive Effluent Release Reports include any changes made during the reporting period to the Process Control Program and to the ODCM pursuant to Technical Specification 6.13 and 6.14, respectively, as well as any major change to Liquid, Gaseous, or Solid Radwaste Treatment System, pursuant to Technical Specification 6.15. It also includes a listing of new locations for dose calculations and or environmental monitoring identified by the Land Use Census pursuant to Technical Specification 3.12.2. The Radioactive Effluent Release Reports also include an explanation as to why the inoperability of liquid or gaseous effluent monitoring instrumentation was not corrected within the time specified in Technical Specification 3.3.7.11 or 3.3.7.12, respectively; and a description of the events leading to liquid holdup tanks exceeding the limits of Technical Specification 3.11.1.4. 110

WENDMENT NO. 3 February 1986 The Radioactive Effluent Report to be submitted within 60 days after January 1 of each year includes an annual summary of meteorological data collected over the previous year. This annual summary will be in the form of joint frequency distributions of wind speed, wind direction, and atmospheric stability. This same report includes an assessment of the radiation doses due to the radio-active liquid and gaseous effluents released from the unit during the previous calendar year. This same report also includes, an assessment of the radiation doses from radioactive liquid and gaseous effluents to Members of the Public due to their activities inside the Site Boundary during the report period. All assumptions used in making these assessments, i.e., specific activity, exposure time and location, are included in these reports. The assessment of radiation doses is'performed in accordance with the method-ology and parameters in the ODCM. The Radioactive Effluent Release Report to be submitted 60 days after January 1 of each year also includes, as required by Technical Specification 3.11.4, an assessment of radiation doses to the likely most exposed Member of the Public from MNP-2 reactor releases and other nearby uranium fuel cycle sources, including doses from primary effluent pathways and direct radiation, for the previous calendar year to show conformance with 40 CFR 190, "Environ-mental Radiation Protection Standards for Nuclear Power Operation".
