2009 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION

2. EffluentConcentration Limits A. Liquids The Effluent Concentration Limits (ECL) for liquids are those listed in 10 CFR 20, Appendix B, Table 2, Column 2. For dissolved and entrained gases the ECL of 2.0E-04 jiCi/ml is-applied. This ECL is based on :the Xe-1 35 concentration in air (submersion dose) converted to an equivalent.

concentration in water as discussed in the International Commission on Radiological Protection (ICRP), Publication 2.

B. Gaseous Concentration limits forgaseous releases are met through compliance with the maximum permissible~dose -rates for gaseous releases as defined in plant;OffsiteDose Calculation Manual (ODCM) and presented in Section 1.A.1 of this report.

3. Average Energy WattsBar's ODCM limits the dose equivalent rates due to the release of-noble gases to-, less than or equal to 500 mrem/year to the total body and less than or equalkto 3000 mrem/ye~arto the skin.

Therefore, the average beta and gamma energies (E) for gaseous effluents as described, in Regulatory Guide 1.21, "Measuring, Evaluation, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-booled Nuclear Power Plants," -are not applicable.

4. Measurements and Approximations of Total Radioactivity Radioactivity measurements performed in support of the WBN Offsite Dose Calculation Manual (ODCM) meet the Lower Limit of Detection requirements given in ODCM Tables 2.2-1 and 2.2-2.

A. Liquid:Effluents Batch (Radwaste and Condensate Demineralizer tanks)

Total gamma isotopic activity concentrations are determined on each Radwaste and Condensate Demineralizer batch tank prior to release. The total activity of-a batch release is-obtained by determining the concentration of each nuclide and then multiplying--by-the volume discharged to arrive at~the curieactivity for each nuclide. The curies of each nuclide are then summed.

Composite samples are maintained and analyzed monthly for tritium and gross alpha, and quarterly for Iron-55, Strontium,89, and Strontium-90. Duringperiods of'no-significant identified primary to secondary leakage, composite samples are not maintained'for Condensate Demineralizer Tank releases and the feedwater tritium concentration lis used to determine the curies of.tritium released from Condensate DemineralizerTank.

2009 WATTS BAR NUCLEAR PLANT EFFLUENTAND WASTE DISPOSAL ANNUALREPORT SUPPLEMENTAL INFORMATION Continuous Releases (Turbine Building Sump, Steam Generator Blowdown, and-Groundwater Sump)

During periods of no significant identified primary to secondary leakage,-thevolume released from, the TBS and SGB is obtained. The TBS tritium concentration is determined via weekly grab, samples. The feedwatertritium concentration is usedito determine the curies of tritium released from SGB. The Groundwater Sump is sampled monthly and analyzed for gross gammaand tritium on a monthly basis and Sr-89, and Sr-90 quarterly. The total activity released, is obtained by determining the concentration of each nuclide and then, multiplyingý bythevolume discharged to arrive at the curie activity for each nuclide.

Monitoring Wells WBN started conducting an investigation of tritium releases to the groundwater' in 2003 due to identification of tritium in three of the four newly installed n-.site monitoring wells.associated with theDOE tritium production program site preparation activity.in December,2002. This study involved pressuretesting of the radwaste discharge: line,.evaporation calculations of the SFP and RWST, installationand sampling of.groundwater wells, inspection of, drainm lines boroscopic investigation of the.SFP, and FTC leak collection system.channels and drains..,In addition to the Six.(6) Radiologocial Environmental Montioring Program (REMP) on-site groundwater monitoring wells, Watts Bar Nuclear Plant also has.37 non-REMP monitoring wells tosupport monitoring the onsite groundwater plume for the presence. or increase of radioactivity. Watts Bar contracted ARCADIS in 2004 to perform .an investigation of the impact tritium, had on, groundwater and perform a site characterization, area of impact,.and preliminary human. health and ecological risk screening. ARCADIS has been contacted to update these same evaluations this year.

The non-REMP on-site monitoring wells are sampled semi-annually;for gamma and tritium. These wells continue to exhibit a downward trend. The tritium. concentrations obtained in 2009 from these non-REMP monitoring wells are listed below. Wells K,L,R, and S samples were-analyzed for Sr-89, Sr-90, Fe-55, and Ni-63 which the results were all nondetectable.

2009 WATTS BAR NUCLEAR PLANT EFFLUENT. AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION Doses from 1-131 Water Ingestion Pathway The radiological environmental monitoring program (REMP),requirements:as specified in Table 3.12-1 from NUREG 1301, "Offsite Does Calculation Manual Guidance: Staandard lRadiological Effluent Controls for Pressurized Water Reactors" April ,1991, requires an 1-131 specific analysis for drinking water pathway samples if the annual dose fr0m 1-.131 is greater than 1 mrem. In order to.evaluate the need for implementation of this additional analysis, the drinking water pathway dose from 1-131 to the maximum organ and age group4was calculated. 'The results reportedhere confirm that the drinking water pathway dose from 1-131 was onlya small fraction of the 1 mrem limit and that the performance of the 1-131 specific analysis is not required for WBN REMP drinking water samples.

2009 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION B.. Fission and Activation Gases Airborne effluent gaseous activity is continuously monitored and recorded. Weekly igrab samples from the auxiliary building andimonthly grab samples from the service building'aire-,taken and analyzed to determine the quantity of noble gas activity released based on the -total flows for the sample period. Also, noble gas samples arecollected and evaluated following startup, shutdown, or rated thermal, power change exceeding 15 percent within one. hour (sampling only required if dose equivalent 1-1i31 concentration in the primary coolant or thenoble gas activity monitor shows that the containment activity has increased more'than a factor- of 3).

The concentration of noble gases released through the shield building exhaust d ue to purging of containment.is determined by using the purge monitor response in.combination: with containment air samples obtained prior to purge. The quantityofactivity released during the purge. is determined using .the duration, flowrate, and concentration of noble gases determined for each purge. Also, noble gas samples are collected and evaluated for ongoing,.containment, purges following startup, shutdown, or rated thermal power change exceeding 15 percent within one hour (sampling only required if DErconcentration in the primary coolantor the noble gas activity monitor shows that the containment activity has increased more thanha-factor-of 3).

The quantity of noble gases released through the shield building-exhaust due to the batch release of waste gas decay tanks is determined by sampling each tank priorito release: The totalcaCtivity released is determined from the total pressure change recordedfor tlhetank during the release.

C. lodines and Particulates in Gaseous Releases Iodine and particulate activity is continuously sampled. Weekly charcoal and particulate samples aretaken from the shield building exhaust and auxiliary building exhausts and fromýcondenser vacuum exhaust during periods of primary to secondary leak. These samples, are analyzed at least weekly to determine the total activity released from the plant based on the'total vent flows recorded for the sampling period.

2009 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION Radiological Impact Introduction Potential doses to maximum individuals and the population around Wattsý Bar are calculated for each quarter as required in Section 5.2 of the Offsite Dose Calculation Manual (ODCM). Measured plant releases for the reporting period are used to estimate these doses. Dispersion of radioactive effluents in the environment is estimated using meteorological data and riverflow data measured during -the period. In this report, the doses resulting from releases are described and compared to limits established for Watts Bar.

Dose Limits The ODCM specifies limits for the release of radioactive effluents, as well as limits for doses to the general public from the release of radioactive effluents. These limits are set well-below the Technical Specification limits which govern the concentrations of radioactivity and doses permissible in unrestricted areas. This ensures that radioactive effluent releases are As Low As Reasonably Achievable.

Dose Calculations Estimated doses to the public are determined using computer. models (the Gaseous Effluent Licensing Code, GELC, and the Quarterly Water Dose Assessment Code, QWATA). These models are based on guidance provided by the NRC (in Regulatory Guides 1.109, 1.111 and 1.113) for determining'the potential dose to individuals and populations living in the vicinity of the plant. The area around the plant is analyzed to determine the pathways through which the public may receive. a dose. The doses calculated are a representation of the dose to a "maximum exposed individual." Some of the factors used in these calculations (such as ingestion rates) are maximum values. Many of these factors are obtained from NUREG/CR-1004. The values chosen will tend to overestimate the dose to this "maximum" person. The expected dose to actual individuals is lower. The calculated doses are presented in Tables 6A, 6B, 7A and 7B.

Doses. From Airborne Effluents For airborne effluents, the public can be exposed to radiation from several sources: direct radiation from the radioactivity in the air, direct radiation from radioactivity deposited on .the ground, inhalation of airborne radioactivity, ingestion of vegetation which contains radioactivity deposited from the atmosphere, and ingestion of milk and beef which contains radioactivity deposited from the atmosphere onto vegetation and subsequently eaten by milk and beef animals.

Airborne Discharge Points All releases from Watts Bar are considered ground-level releases. The ground-level Joint Frequency Distribution (JFD) is derived from wind speeds and directions measured 10 meters above ground and from the vertical temperature difference between 10 and 46 meters, and are presentedfor each quarter on pages E1-32 through E1-59.

E1-23

2009 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION Radiological Impact Meteorological Data Meteorological variables at Watts Bar are measured continuously. Measurements collected include wind speed, wind direction, and temperature at heights of 10, 46, and 91 meters above the ground. Quarterly joint frequency, distributions (JFDs) are calculated for each release point using the appropriate levels. of meteorological data. A joint frequency distribution gives the percentage of the time in a quarter that the wind is blowing out of a particular upwind compass sector in a particular range of wind speeds for a.given stability class A through G. The wind speeds are divided into nine wind speed ranges. Calms are distributed by direction in proportion to the distribution of non-calm wind directions less than 0,7 m/s (1.5 mph). Stability classes are determined from the vertical temperature difference between.two measurement levels.

External Exposure Dose Dose estimates for maximum external air dose (gamma-air and beta-air doses) are made for points at and beyond the unrestricted area boundary as described in the Watts Bar ODCM. The highest of these doses is then selected.

Submersion Dose External doses to the skin and total body, due to submersion in a cloud of-noble gases, are estimated for the nearest residence in each sector. The residence with the highest dose is then selected-from all sectors.

Organ Dose Doses to organs due to releases of airborne effluents are estimatedfor the inhalation, ground contamination, and ingestion pathways. The ingestion pathway is further divided into four possible contributing pathways: ingestion of cow/goat milk, ingestion of beef, and ingestion of yegetables. Doses from applicable -pathways are calculated for each real receptor location identified -in the most recent land use survey. To determine the maximum organ dose, the doses.from.the pathways are summed for each receptor. For the ingestion dose, however, only those pathways that exist for each. receptor are considered in the sum, i.e., milk ingestion doses are included only for locations where milk is consumed without commercial preparation and vegetable ingestion is included only for those locations where a garden is identified. To conservatively account for beef ingestion, a beef ingestion dose equal to that for the highest unrestricted area boundary location is added to each identified receptor. For ground contamination, the.

dose added to the organ dose being calculated is, the total body dose calculated for that location, i.e., it is assumed that the dose to an individual organ is equallto the total body dose.

Doses from airborne effluents are presented in Tables 6A and 6B.

Doses From Liquid Effluents For liquid effluents, the public can be exposed to radiation from three sources: the ingestion of water from the Tennessee River, the ingestion of fish caught in the Tennessee River, and direct exposure from radioactive material deposited on the river shoreline sediment:(recreation).

El-24

2009 WATTS BAR NUCLEAR' PLANT EFFLUENT AND WASTE DISPOSAL ANNUAL REPORT SUPPLEMENTAL INFORMATION Radiological Impact The concentrations of radioactivity in the Tennessee River are, estimated by a computer model which uses measured. hydraulic data downstream of Watts Bar. Parameters used to determine thetdoses are based on guidance given by the NRC (in Regulatory Guide 1.109) for maximum ,ingestion. rates,, exposure times, etc.

Wherever possible, parameters used in the dose calculation are site specific use factors determined by TVA. The models.that are-used to estimate doses, as well as the parameters input to the models, are described in detail in the WattsBar ODCM.

Liquid Release.Points and River Data Radioactivity concentrations in the Tennessee River are calculated assuming that releases in liquid effluents are continuous. All routine liquid releases from Watts Bar, located at Tennessee River Mile 528.5, are made through diffusers which extend into the Tennessee River. It.is assumed that releases to the river through these diffusers will initially be entrained in one-tenth of the water which flows past the plant. The QWATA code makes the assumption that this mixing condition holds true until the water is completely mixed at Tennessee River Mile 510.0.

Doses are calculated for locations within a 50 mile radius downstream of the plant site. The maximum potential recreation dose is calculated for a location immediately downstream from the plant outfall. The maximum individual dose from ingestion of fish is assumed to be that calculated for the consumption of fish caught anywhere between the plant and the first downstream dam (Chickamauga Dam). The maximum individual dose from drinking water is assumed to be that calculated -at the nearest downstream.public water supply (Dayton, TN). This could be interpreted as indicating that the maximum individual, as assumed for liquid releases from Watts Bar, is an individual who obtains all of his. drinking water at Dayton, TN, consumes fish caught from the Tennessee River between Watts Bar and Chickamauga'Dam, and spends 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> per year on the shoreline just below the outfall from Watts:Bar. Dose estimates for the maximum individual due to liquid effluents for each quarter in the period are presented in TablesIA 'and 7B, along with the average river flows past the plant site for the periods.

Population Doses Population doses for highest exposed organ due to airborne effluents are. calculated for an estimated 1,066,600 persons living within a 50-mile radius of the plant site. Doses from external: pathways and inhalation are based on the 50-mile human population distribution. Ingestion population doses are calculated assuming that each individual consumes milk, vegetables, -and meat produced within the sector annulus in which he resides. Doses from external pathways and inhalation are based on the 50-mile human population distribution.

Population doses for total body and the maximum exposed organ due to liquid effluents are calculated for the entire downstream Tennessee River Population. Water ingestion population doses are calculated, using actual population figures for downstream public water supplies. Fish ingestion population doses are calculated assuming that all sport fish caught in the Tennessee River are consumed by the Tennessee River population. Recreation population doses are calculated- using actual recreational data on the number of shoreline visits at downstream locations.

Population dose estimates for airborne and liquid effluents are presented in Tables 6A, 6B, 7A and 7B.

2009 WATTS BAR NUCLEAR PLANT EFFLUENT AND WASTE DISPOSAL ANNUALCREPORT SUPPLEMENTAL INFORMATION Radiological Impact Direct Radiation External gamma radiation levels were measured by thermoluminescent dosimeters (TLDs).deployed around WBN as part of the offsite Environmental Radiological Monitoring Program. The quarterlygamma radiation levels determined from these TLDs during this reporting period averaged 12:'0 mR/quarter. at onsite (at or near the site boundary) stations and 11.0 mR/quarter at offsite stations or 1.00 mR/quarter higher onsite than at offsite stations. This difference is consistent with levels. measured for preoperation and construction phases of the WBN plant site where the average radiation levels onsite were generally 2-6 mR/quarter higher than the levels offsite. This may be attributable to natural variations in environmental radiation levels, earth moving activities onsite, the mass of concrete employed in the: construdtibn of the plants, or other undetermined influences. Fluctuations in natural background dose rates and in TLD :readings tend to mask any small increments which may be due to plant operations. Thus, therewas no identifiable increase in dose rate levels attributable to direct radiation from plant equipment and/or gaseous, effluents.

Dose To A.Member OfThe Public Inside.The Unrestricted Area Boundary As stated in the Watts Bar Offsite Dose Calculation Manual, an evaluation of the dose to a member of the public inside the unrestricted area boundary is performed for a hypothetical TVA employee who works just outside the restricted area boundary for an entire work year (2000 hours0.0231 days <br />0.556 hours <br />0.00331 weeks <br />7.61e-4 months <br />). Results from-onsite quarterly TLD measurements indicated that the highest annual TLD reading outside, Radiological Control Areas was 92 mrem. Using this value, subtracting an annual background value of approximately. 48 mrem/year (see previous section), and multiplying by the ratio of the occupancy times (2000/8760), the -highest external dose to a member of the public inside the unrestricted area boundary would be 10 mrem. The doses due to radioactive effluents released to the atmosphere calculated in this report would not add a significant amount to this measured dose. This dose is below the 10 CFR 20 annual limit of 1:00 mrem.

Total Dose To determine compliance with 40 CFR 190, annual total dose contributions to the maximum individual from Watts Bar radioactive effluents and all other nearby uranium fuel cycle sources are considered.

The annual dose to any organ other than thyroid for the maximum individual is conservatively estimated by summing the following doses: the total body air submersion dose for each quarter, the critical organ dose (for any organ other than the thyroid) from airborne effluents for each quarter from ground contamination, inhalation and ingestion, the total body dose from liquid effluents for each quarter, the-maximum organ dose (for any organ other than the thyroid) from liquid effluents for eachý quarter, and any identifiable increase in direct radiation dose levels as measured by the environmental monitoring program. This~dose is. compared to the 40 CFR 190 limit for total body or any organ dose (other than. thyroid) to determine compliance.

The annual thyroid dose to the maximum individual is conservatively estimated byý summing.the following doses: the total body air submersion. dose for each quarter, the thyroid dose from airborne effluents for each quarter, the total body dose from liquid effluents for each quarter, the thyroid dose from liquid effluents for each quarter, and any identifiable increase in direct radiation dose levels as measured...by, the environmental monitoring program. This dose is compared to the 40 CFR 190 limit for thyroid dose to determine compliance. Cumulative annual total doses are presented in Table 8.

1.0 INTRODUCTION

The Watts Bar Nuclear Plant (WBN) Offsite Dose Calculation Manual (ODCM)"is a supporting documentof the WBN Technical Specifications (TS) required by WBN TS 5.7.2.3; The ODCM isdividedinto two major parts:,Controls (Sections 1 through 5) and program descript!on(Sections' 6. through 9). References are given in each section ýas applicable and are further described in Section 10.0.

The first part of the ODCM (Sections 1 through 5) contains:

1) Radioactive-Effluent'Controls required by Section 5.7.2.7 of the.WBN TS; 2). Radiological Environmental Monitoring Controls required by 10 CFR Part 50, Appendix.I,Section IV.B;
3) Controls for Meteorological Monitoring Instrumentation;
4) Descriptions of the information that should be included in the Annual RadiologicalEnvironmental Operating and Radioactive Effluent Release Reports required by WBNl-echnicaF'Specifications 5.9.2 and 5.9.3;and
5) Administrative Controls for the ODCM requirements.

These sections of the'document have been prepared using the guidance provided in NUREG-1301 (Reference 1) and draft Nuclear Regulatory Commission Generic Letter (Reference 2). Exceptions to this guidance have been documented in Appendix B to the ODCM.

The second part of the ODCM (Sections 6 through 9) contains the methodologies and-parameters used to:

1) Calculate offsite doses resulting from radioactive gaseous and'liquid effluents;
2) Calculate gaseousand liquid effluent monitor Alarm/Trip setpoints;,and,
3) Conduct.the Radiological Environmental Monitoring Program,(REMP).

These methodologies and parameters were developed using the guidance in NUREG-01.33 (Reference 3);

Regulatory Guide 1:.109 (Reference 4); Regulatory Guide 1.111, (Reference 5); Regulatory Guide 1.113 (Reference 6); ,Regulatory Guide 1.21 (Reference 7); and Radiologicail AssessmentBranch Technical Position onEnvironmental Monitoring (Reference 8). Where any methodology or parameter. differs from the guidance provided,1i the, above documents, it has been documented in the .text and references given for the source of the information.

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 6 of 195 1.0/2.0 - CONTROLS AND SURVEILLANCE REQUIREMENTS 1/2.0 APPLICABILITY CONTROLS 1.0.1 Controls shall be met during the MODES or other specified conditions in the Applicability,,'except as provided in Control 1.0.2.

1.0.2 Upon discovery of a failure to meet a Control, the Action(s) of the associated Conditions shall be met.

If the Control is metor is no longer applicable prior to expiration;of theAction(s), completion of the Action(s) is not required unless otherwise stated.

SURVEILLANCE REQUIREMENTS 2.0.1 Surveillance Requirements(SR) shall be met during MODES or other conditions in theApplicability for individual Controls, unless otherwise stated in the SR. Failure to meet the Control occurs when a surveillance isfailed or when conditions occur between surveillances--that~would result.in affailed surveillance iftesting was performed. Failure to perform a surveillance within the specified frequency shall befailureto meet theControl except as provided in SR 2.0.3. Surveillancesdo, not have to- be performed on inoperable equipment or variables outside specified limits.

2.0.2 The specified frequency foreach SR is met if the surveillance is performed within.1.25 times.the interval specified in the frequency, as measured from the previous performance or.asmeasured from a time a specified condition of the frequency is met.

For frequencies specified'as "once," the above interval extension does not apply.

If an Action requires periodic performance on a "once per..." basis, the above frequency extension applies to each performance after the initial performance.

Exceptions to this SR control section are stated in the individualSRs.

2.0.3 If it is discovered that a surveillance was not performed within its specifiedfrequency, then compliance with therequirement to declare the Control not metrmay be delayed, from the time of discovery, up to 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />sor up to the limit of the specified frequency, whichever is less. This delay period is permitted to allow performance of the surveillance.

If the surveillance is not performed within the delay period, the Control must'irmmediately be declared not met, and the applicable Action(s) must be entered. The Action(s) begin 'immediately upon expiration of the delay period.

When the surveillance"is performed within the delay period and the surveillance isnot met,. the Control must immediately be entered. The Action(s) begin immediately upon failureto meet the surveillance.

2.0.4 Entry:-into a MODE or other specified condition in the Applicability of a Control shall not be made unless the Control's surveillances have been met within .their specified frequency. This provision shall not prevent passage through to MODES or other specified conditions incompliance with Action(s).

The alarm/trip setpoints,of these channels shall be determined in accordance with the methodology and parameters in.ODCM Section 6.2.

APPLICABILITY: This requirement is applicable as shown in Table 1.1-1.

ACTION:

a. With a radioactive liquid effluent monitoring instrumentation, channel alarrm/tripsetpoint less conservative than required by the above control, immediately suspend the release ofrradioactive liquid effluents monitored by the affected channel, or declare the channel inoperable, or change the setpoint so that it is acceptably conservative.
b. With less than .the minimum number of radioactive liquid effluent monitoring instrumentation channels OPERABLE, take the action shown in Table 1.1-1. Restore the inoperable instruments to OPERABLE statusrwithin 30 days and, if unsuccessful,.explain in the next Annual.Radioactive Effluent Release, Report, pursuant to ODCM Administrative Control!52,. why the inoperabil ty was not corrected within 30 days.
c. The provisions of SR 2.0.4 are not applicable. Report all deviations' in the Annual2 Radioactive Effluent Release Report.

TABLE NOTATION The LLD is defined for the purpose of these Controls as the smallest concentration of radioactive material in a sample that will yield a net count, above system, background, thatwilLbei detected with 95% probability with-only a 5% probability of falsely concluding that a blank observation represents a "real" signal. (Reference 8)

For a particular measurement system (which may include radiochemical separation):

4 66 LLD = . Sb E V 2.22E6 Y exp(-XAt) where:

LLD = the "a priori" lower limit of detection (microcurie per unit mass or volume).

Sb = the standard deviation of the background counting rate or of the countingrate of a blank sample as appropriate (counts per minute).

E =.the counting efficiency. (counts per disintegration).

V = the sample size (units of mass or volume).

6 2.22x10 = the number of disintegrations per minute per microcurie.

Y = the fractional radiochemical yield, when applicable.

I = the radioactive decay constant for the particular radionuclide (s-1), and Dt = the elapsed time between midpoint of sample collection and time of counting (s). The definition of Dt applies only to the calculation of the LLD. A more rigorous treatment of the buildup and decay during the sample collection and/or counting interval(s) may be applied to actual sample analysis if desired.

It should be recognized that the LLD is defined as an a priori (before the fact).limit representing;the capability of a measurement system and not an a posteriori (after the fact)ý limit for a particular, measurement.

Typical values of E, V, Y, and At should be used in the calculation.

2 A batch release is the discharge of liquid wastes of a discrete volume. Prior to samplingrfor analyses, each batch shall be isolated and then thoroughly mixed by the method described in appropriate plant procedures to assure representative sampling.

3 The principal gamma emitters for which the LLD Control applies exclusively arethe following' radionuclides: Mn-54, Fe-59, Co-58, Co-60, Zn-65, MO-99, Cs-134, Cs-137, Ce-141. Ce&144 shall also be measured, but with -an LLD of 5x10- 6 gtCi/ml. This list does not mean that only.these, nuclides are to be considered. Othergamma peaks which are identifiable, together with~thoseo0f the above nuclides, shall also be analyzed and reported in the Annual Radioactive Effluent Release.Report pursuant to ODCM Administrative Control 5.2, in the format outlined in Regulatory Guide 1.21, Appendix B, Revision 1, June 1974.

4 A laboratory composite sample is one prepared by combining representative samples from each release into one well-mixed, homogeneous sample. The volume of sample added to thecomposite from each release shall be proportional to the release volume. The composite ýsample shall' be preserved according to plant procedures as appropriate.

1/2.1.2 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 and potential releases of gaseous effluents. The radiation monitor alarm/trip setpoints for each release point are based on the radioactive noble gases in gaseous effluents. It is not considered practical to apply the instantaneous alarm/trip setpoints to. integrating radiation monitors sensitive to radioiodines, 'radioactive materials' in particulate form, and radionuclides other than noble gases. The alarm/trip setpoints for these instruments shall be calculated and adjusted in~accordance with the methodology and parameters in ODCM Section'7.1 to ensure'that'the alarm/trip will occur prior to exceeding the.dose rate limits of ODCM Control 1.2.2.1.

1/2.1.3,METEOROLOGICAL INSTRUMENTATIONIDATA The OPERABILITY of the meteorological instrumentation ensures that sufficient meteorological data is available for estimating. potential radiation doses to the public as a result of routine or accidental, release of radioactive materials to the atmosphere. This capability is required to evaluate the need for initiating protective measures to protect the health and safety of the public and.is consistentwith the recommendations of Regulatory Guide 1.23, "Onsite Meteorological Programs," February 1972, ANSI/ANS-3.11-2000, "Standard for Determining Meteorological Information at-Nuclear Power Sites,"

2000, Regulatory Guide 1.97, "Instrumentation for Light-Water-Cooled Nuclear Power Plants:to Assess Plant and Environs Conditions During and Following an Accident," May 1983, and. Supplement Ito NUREG-0737, "Requirements for Emergency Response Capability (Generic Letter 82-33),"

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 48 of 195 1/2.2 RADIOACTIVE EFFLUENTS 1/2.2.1 LIQUID EFFLUENTS 1/2.2.1.1 CONCENTRATION This Control is provided to ensure that the concentration of radioactive materials released inliquid waste effluents to UNRESTRICTED AREAS will be less than 10 times the concentration values specified in Appendix B, Table 2, Column 2 to 10 CFR 20.1001-20.2402. It provides operational flexibility~for releasing liquid effluents in concentrations to follow the Section IL;A and Il.C design objectives of Appendix I to 10 CFR 50. This limitation provides reasonable 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 50, to a MEMBER OF THE PUBLIC, and.(2) restrictions authorized by 10 CFR 20:.1 301(e). The concentration limit for dissolved or entrained noble gases is based upon the assumption that Xe-1 35 is the controlling radioisotope and its concentration in air (submersion) was converted to an equivalent concentration in water. This specification does'not affect the requirement to comply with the annual limitations of 10 CFR 20.1301 (a).

This Control applies to the release of radioactive materials in liquid effluents from all reactors. 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 description of the LLD, and other detection limits can be found in HASLProcedures Manual, HASL-300, Currie, L. A., "Limits for QualitativeDetection and Quantitative, Determination - Application to Radiochemistry," Anal. Chem. 40, 586-93 (1968), and Hartwell, JI K., "Detection Limits for Radioanalytical Counting Techniques," Atlantic Richfield Hanford Company Report ARH-SA-215 (June 1975).

1/2.2.1.2 DOSE This Control is provided to implement the requirements of Sections ll.A; Ill.A, and IV A of Appendix I, 10 CFR 50. The Control implementsthe guides set forth in Section ll.Aof Appendixl. Compliance with this Control will be considered to demonstrate compliance with the 0.1 rem limit Of 10CFR20.1301(a)(1) per 56 FR 23374. The ACTION 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 materials in liquid effluents to UNRESTRICTED AREAS will be kept "as low as reasonable achievable."

Also, for fresh water sites with drinking water supplies which 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 CFR141. 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 equations specified 'in the ODCM section for calculating the doses due to the actual release rates of radioactive.materials in liquid effluents are consistent with the methodology provided in Regulatory Guide 1.1 09 "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purposes of Evaluating Compliance with 10 CFR Part 50 Appendix I," Revision 1, October 1977 and Regulatory Guide 1:113, "Estimating.Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I," April 1977.

This Control applies to the release of radioactive materials in liquid effluents from each unit at the'site.

When shared Radwaste Treatment Systems are used by more than one unit on a site, .the wastes from:all units are mixed for shared treatment; by such mixing, the effluent releasescannot accurately be ascribed to a specific unit. An estimate should be made of the contributions from each unitbased~on input conditions, e.g., flow to each of the radioactive producing units sharing the Radwaste Treatment System.

El-110

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 49 of 195 For determining conformance to controls, these allocations from shared Radwaste Treatment Systems are to be added to the releases specifically attributed to each unitto obtain-the totalrelease per site.

For those nuclides whose activities are determined from compositesamples(as noted in Table 2.2-1), the concentrations for the previous composite period will be assumed as the concentration for the next period to perform the calculations in ODCM Sections 6.1 and 6.3.

1/2.2.1.3 LIQUID RADWASTE TREATMENT SYSTEM The OPERABILITY of the LRTS ensures that this systemwill be available for use Whenever liquid effluents require treatment prior to release to the environment. The Control that the appropriate portions of this system be used when specified provides assurance that the releases of radioactive materials in liquid effluents will be kept-"as low as reasonably achievable." This requirement implements the requirements of 1'0 CFR 50.36a, General Design Criteria 60 of Appendix A to 10 CER 50 and the design objective given in Section II.D of'Appendix I to 10 CFR 50. The specified'limits governing the use of appropriate portions of.the liquid radwaste system were specified as a suitable'fraction of the dose design objectives set forth inSection IL.A of Appendix 1,10 CFR 50, for liquid' effluents.

This Control, applies to the release of'radioactive materials in liquid effluents from each unit~at the' site.

When shared, LRTS are used'by more than one unit on a site, the wastes;from~all units are mixed for shared treatment; by such mixing, the effluent releases cannot accurately-be ascribed.toa specific unit.

An estimate should be made of the contributions from each unit based-on input.cond'itions,ý e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent'releases be allocated' equally to each of the'radioactiveproducing units sharing the LRTS. For determining conformance:ýto.controls',

these allocations from shared LRTS are to be added to the releases specifically attributed to each unit to obtain the total release per site.

1/2.2.2 GASEOUS EFFLUENTS 1/2.2.2.1 DOSE RATE This Control provides 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 in excess of the design objectives-of Appendix I to 10 CFR 50. This Control is 'provided to ensure that gaseous effluents from all units on the site will be appropriately controlled. It provides operational flexibility for releasing gaseous effluents to satisfy the.Section I.A and II.C design objectives'of Appendix Ito 10 CFR 50.. For MEMBERS OF THE PUBLIC who may at times be within the CONTROLLEDor RESTRICTED AREAS, the occupancy of that MEMBER OF THE PUBLIC will usually be sufficiently low to compensate for the reduced atmospheric dispersion relative to that for the UNRESTRICTED AREA BOUNDARY. Examples of calculations for such MEMBERS OF THE PUBLIC, with the appropriate occupancy factors, shall be given 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 UNRESTRICTED AREA BOUNDARY to <500 mrem/y to the total body or to *3000 mrem/y to the skin. These limits also restrict, at all times, the corresponding thyroid dose rate above background'to a child via the inhalation pathway to *1500 mrem/y. This Control does not affect the requirement to comply with the annual limitations of 10 CFR 20.1301 (a).

This requirement applies to'the release of radioactive material in gaseous effluents from all -reactors at the site.

The required detection capabilities for radioactive materials in gaseous waste samples aretabulated in terms of the lower limits of detection (LLDs). Detailed description of the LLD, and other detection ýlimits canbe found in HASL Procedures Manual, HASL-300,'Currie, L. A., "Limitsfor Qualitative. Detectionand 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).

For those nuclides whose activities are determined from composite samples (as noted in Table i.2-1), the concentrations for the previous composite period will be assumed as the concentration for the next period to perform the calculations'in ODCM Sections 7.2.

established in ODCM Section.7.3 for calculating the doses due tothe .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 Man from Routine Releases of Reactor Effluents for the:Purposes of Evaluating Compliance .with 1.0 CFR Part 50, Appendix I,"Revision l, October 1977 and Regulatory Guide 1'11.1, "Methods for Estimating Atmospheric Transportand Dispersion.of.Gaseous-EfflUe'nts in Routine Releases from Light-Water Cooled Reactors," Revision 1, July 1977. The equations provided for determining the air doses at and beyond the UNRESTRICTED AREA BOUNDARY are based uponthe historical average atmospheric conditions.

This Control applies to the release of gaseous effluents from each reactorat the site. Whenshared Radwaste Treatment Systems are used by more than one unit on a site, the wastesfrom all Units are mixed for sharedý treatment; by, such mixing, the effluent releases cannot accurately berascribed to~a specificunit. An estimate should be made of the contributions from~each unit based on input conditions, e.g., flow rates and radioactivity concentrations, or, if not practicable, the treated effluent-releasesbe allocated equally to each ofthe radioactive producing units sharing the Radwaste'Treatment System. For determining conformance to requirements, these allocations from shared Radwaste Treatment Systems are to be added to the releases specifically attributed to each unit to obtain the total release per site.

IILA and :IV.A of Appendix I, 10 CFR 50. The Control'implements the guides set forth in Section IL.C.ofAppendix I. Compliance with this control will be considered to demonstrate compliance with the.&Orem lin'it.of:lo CFR 20.1301 (a)(1) per 56 FR23374. The ACTION to be taken provides the requiredoperatingrflexibility and at.the same time implements the guides set forth in Section IV.A of Appendix Ito assure that'the releases of radioactive material in gaseous effluents will be kept "as low as reasonably achievable." ODCM Section .7.4 calculational methods specified in the Surveillance Requirement implement the: requirements in Section III.A of Appendix I that.conformance with the guides of Appendix I be shownby calculational procedures based on models and: data such that the actual exposure of a MEMBER OF THE PUBLIC through appropriately modeled pathways is unlikely to be substantially underestimated. ODCM Section 7A calculational methodology and parameters for calculating the doses due to~the actual release rates of.the subject materials are consistent with the methodologies provided in NUREG/CR-1004, "A Statistical Analysis of Selected Parameters for Predicting Food&Chain Transport and InternalDose of Radionuclides,".October 1979 and Regulatory Guide 1.109, "Calculation,of Annual Doses to Man from Routine Releases of Reactor Effluentsfor the Purposes ofEvaluating Compliance with -10 CFR Part 50, Appendix I,"Revision 1, October 1977 and Regulatory Guide 1.111* "Methods for:EEstimating 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. The release rate controls for 1-131, 1-1.33, tritium and particulate radionuclideswith half-lives greater than eight days are dependent;upon the existing radionuclide pathways to, man in the areas at and beyond the UNRESTRICTED AREA BOUNDARY.

The pathways that were examined in the development of the 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 animalsand beef: producing.^animals graze with consumption of the milk and beef by man, and (4) deposition'on the ground, with subsequent exposure of man.

112.2.2:4 GASEOUS RADWASTE TREATMENT SYSTEM The OPERABILITY of the WASTE GAS HOLDUP SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM ensures that the systems will be available for.use whenever, gaseous effluents require treatment prior to release to the environment. The Control thatthe 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 reasonably achievable." Thisrequirement implements the requirements of 10 CFR 50.36a, General Design Criteria.60 of Appendix A-to 10 CFR 50, and thedesign objectives given in Section IL.D of Appendix I to 10 CFR 50. The :specified limits governing the use of appropriate portionsof the systems were specified as'a suitable fraction of the dose design objectives set forth in Section II.B and II.C of Appendix 1,10 CFR 50, for gaseous effluents.

This Controlapplies tothe release of radioactive materials in gaseous effluents from each'unit~at the site.

When shared Radwaste Treatment Systems are used by more than one unit on asite,-the wastes from all units are mixedfor shared treatment; by such mixing, the effluent releases cannot.accurately be.ascribed to a specific unit. An estimate should be made of the contributions from each unit[basedion. input conditions, e.g., flowrates and radioactivity concentrations, or, if notpracticable, the~treated effluent releases be allocated-equally to each of the radioactive producing units sharing the;Radwaste Treatment System. For determining conformance to Controls, these allocations from sharedRadwasteTreatment Systems are to be added to the releases specifically attributed to each unit to obtainwthe total release per site.

1/2.2.3 TOTAL DOSE This Control is provided to meet the dose limitations of 40 CFR 190 .that have been incorporated into 10 CFR 20.1301(d). The Control requires the preparation and submittal of a Special Report whenever the calculated doses due to releases of radioactivity and to radiation from uranium fuel cycle sources exceed 25 mrem to-the total body or any other organ, except the thyroid, which shall be limited to, less than or.equal:to 75 mrem. For sites containing up to 4 reactors, it is. highlyunlikely.that the~resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR 1950if.the individual reactors remain within twice the dose design objectives of Appendix I and if direct radiation doses from the units and from outside storage tanks are kept small. The Special Report will describe a course of action that should result in the limitation of annual dose to a MEMBER OF THE.PUBLIC to within the40 CFR.190 limits. For the purposes of the Special Report, it may be assumed thatfthe 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 PUBLICisestimatedto exceed therequirements of 40 CFR.Part 190, the Special Report.with a request for a variance (provided the release.conditions resulting in violation of 40 CFR 190 have not already been corrected), in accordance with.the provisions of 40.CFR 190.11 and 1.0 CFR 20.2203(a)(4), is considered to be a timely request and fulfills1the requirements of 40 CFR 190 until NRC staff action is completed. The.variance only, relates to the:limits of 40 CFR 190, and does not apply in any way to the other requirements for dose limitation of 10 CFR 20, as addressed-in ODCM Controls 1.2.1.1 and 1.2.2.1. 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. Demonstration of compliance with the limits of 40 CFR 190 or with the design objectives of Appendix I.to 10 CFR 50 will be considered to demonstrate compliance with.the 0.1 rem limit of 10 CFR 20.1301.

The requirements for evaluating compliance with 40 CFR 302 are added to ensure compliance with these limits. The regulation states that federally permitted releases do not have to determine compliance with the reportable quantities unless the permitted release allowance is exceeded.

WBN OFFSITE DOSE CALCULATION MANUAL Revision.,22 0 (ODCM) Page 52 of 195 1/2.3 RADIOLOGICAL ENVIRONMENTAL MONITORING 1/2.3.1 MONITORING PROGRAM The Radiological Environmental Monitoring Program required by this.Control 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 implementsSection IV.B.2 of Appendix I to 10 CFR 50 and thereby supplements the Radiological Effluent Monitoring;Program by verifying that the measurable concentration of-radioactive materials and levels of radiation arenot higher-than expected on the basis of the effluent measurements and modeling of the environmental exposure pathways.

Guidance for this'monitoring program is provided by the Radiological Assessment BranchTechnical Position on Environmental Monitoring, Revision 1, November 1979. The initiallyspecifiedl monitoring program will be effective for at least the first three years of commercial operation. Following this period, program' changes may be initiated based 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'2.3-3 are consideredoptimum for routine' environmental measurements in industrial laboratories. It should be recognized that the LLD is defined as an a priori (before the fact) limit representing the capability of a measurement system.and not as a posteriori (after the fact) limit for a particular measurement.

Detailed description of the LLD,.and other detection limits can be found in HASL Procedures:Manual, HASL-300, 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).

112.3.2 LAND USE CENSUS This Control is provided to ensure that changes in the use of areas at and beyond the UNRESTRICTED AREA BOUNDARY are identified and that modificationsto the monitoring program are made, if required by the results of that census. The best information from the door-to-door survey, mailsurvey, telephone survey, aerial survey, or by consulting with local agricultural authorities shall be used. This census satisfies the requirements of Section IV.B.3 of Appendix I to 10-CFR 50. Restricting Ithe census-to gardens of greater than 50 m2 provides assurance that significant exposure pathways via leafy vegetables will be identified and monitored since a garden of this size is the minimum required to provide the quantity (26 kg/y) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption:by a child.

To determine this minimum garden size, the following assumptions were. used, 1) that 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 2 .

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 641of 195 6.0 -;LIQUID EFFLUENTS INTRODUCTION Radioactive liquideffluents from WBN enter the UNRESTRICTED AREA through'the diffusers into the Tennessee<River. There arefourplant systems from which'radioactive effluentsare released. These are the Liquid Radwaste Treatment'System (LRTS), the Condensate Derriineralizer Systemý,the:Turbine Building Sump (TBS); and'the Units 1 and 2 Steam Generator BlowdownJ(SGBD). :Figure 6.1 provides an outline of these liquid release paths with associated radiation monitors.

The LRTS, the Condensate Demineralizer System and the SGBDs flow into the .Cooling:Tower'Blowdown (CTBD) for dilution. Each of these release paths is also monitored by a radiation monitor. These monitors perform two mainfunctions: to identify any unexpectedradioactivity releases, and to ensure. that the concentration.limits of ODCM Control 1.2.1.1 are not exceeded. Each monitor haýsan alarm/trip:setpoint which will alarm if the monitor's setpoint is exceeded. Alarm and trip functions are not provided Iby separate devices, therefore the alarm/trip setpoint is a single calcuiated value. The monitors onthe Radwaste, Condensate Demineralizer,.-and SGBDsystemswill alarm and isolate: any release which exceeds thealarm/trip:setpoint. The TBS radiation monitor will alarm if the setpoint is exceeded, but this monitor does not have an ,isolation function.

Releasesare made as either a batch or continuous release. Releases from Radwaste Tanks, (see Figure 6.2) and the Condensate Demineralizer tanks (see Figure 6.3),are made. as batch, releases. The TBS and SGBD are continuous releases when flow exists.

For batch releases, any~tank to be released is sampled for radioactivity, as.described in ODCM Section 6..1,1. .The tank contents are analyzed to determine the maximumallowable:release flow rates to ensure compliance with the,'concentration limits of ODCM Control 1.2,1.1 as described'in ODOM Section 6.1.2. The sampling results'are also used to determine a setpoint for the associated radiation monitor for the release in accordance with ODCM Section 6.2.3.

For continuous releases, the pathways are sampled for radioactivity periodically,.as described in ODCM Section 6.1.1. The samples are analyzed to ensure compliance with the concentration limitsof 0f.DCM Control 1.2.1.1,,.as described in ODCM Section 6.1.2. The sampling resultsare also0used to determine a setpoint for the associated* radiation monitor for the release in accordance with oDCM Section 6. 2.3.

Dose, calculations are performed for each sampling period, or release, as-applicable,, to determine compliance with ODCMControl 1.2.1.2 as detailed in ODCM Sections 6.3 and 6.4. Ornce permonth, the projected *dose is calculated, as outlined in. Section 6.5, to determine compliance: With 0OCM Control 1.2:1.3.. The calculational methodologies are based on the guidance provided in NUREG 0133 and Regulatory'Guide 1. 109.

The quantities of each radionuclide identified and released are input into a more rigorous calculation methodology,, described in :ODCM Section 6.6, to determine the individual .and'population doses to be reportedto.the NRC in theAnnual Radioactive Effluent Release Report. These dose methodologies are based on.the guidance provided in Regulatory Guide 1.109.

The routine release points for liquid radwaste are the Monitor-Tank and the Cask Decontamination CollectorTank (CDCT). The:Monitor Tank has a.capacity of 20,000gal and can be released at a maximum design flowl rate sof1150 gpm.-'The CDCT has a capacity of 15;000 gal and can be released at a maximum design flow rate.of 100 gpm. The Monitor Tank and CDCT discharge to the Cooling Tower Blowdown line asa batch release-and are monitored by radiation monitor 0-RE-90-122. There is a flow interlock-on the CTBD'which suspends the release if the flow is less than,20,000 gpm.

Condensate Demineralizer System The Condensate Demineralizer System liquid wastes are released-from the High Crud-Tanks (HCT-A and -B), the Neutralization:Tank,- and the Non-Reclaimable Waste Tank (NRWT)."

Recirculation times to ensure adequate mixing will be established by testing. Periodically, checks will be made; to.ensure a representative mixing of tank contents. Prior to any batch release, a grab samplewill be takenand analyzed in accordance with Table 2.2-1.

Releases from the steam generator blowdown and turbine building sump are considered continuous. For continuous releases, daily grab or composite samples will be taken on days when releasesare being made and analyzed in accordance with Table 2.2-1.

Composite samples are maintained during periods of radioactive discharge fromall pathways (as required by Table 2.2-1) to determine the concentration of certain nuclides (H-3, Fe-55, Sr-89, Sr-90, and gross alpha). For those nuclides whose activities are determined from composite samples, the.

concentrations for the previous. composite, period can be assumed as the concentration for the.next period to perform the calculations in Sections 6.3 and 6.5. The actualmeasured concentrations will be used for the dose calculations described in Section 6.6.

A maximum allowable waste flow rate, which will ensure compliance with ODCM Control 1.2.1.1, will be determined using Equations 6.1 and 6.2. Setpoints for the release are determined as described in Section 6.2. Dose;calculations are performed in accordance with Section 6.3 6.1.2 Effluent Concentration Limits (ECL)-Sum of the Ratios To determine release parameters toensure compliance with ODCM Control: 1.2.1..,a sum of the .ratios calculation is performed. The sum of the ratios (R) for each release point~will be calculated by the following relationship.

Cj R=Xi ECL (6.1) 1 where:

R = the sum of the ratios for the release point.

ECLi = the ECL of radionuclide i, pCi/ml, from 10 CFR 20, Appendix B, Table 2,Column 2.

Ci = concentration of radionuclide i, gCi/ml.

The sum of the ECL ratios must.be < 10 following dilution due to the releases from anyor all of,the release points described above. The ECL ratios for releases from the Turbine Building Sump will be < 10 at the sump.

El-128

WBN OFFSITE DOSE CALCULATION MANUAL Revision,22 0 (ODCM) Page:67 of1195 The following relationship is used to ensure that this criterion is met:

RTBS + f1R1 + f2 R2 + f3 R3 + f4 R4 < 0.0 F (6.2) where:

RTBS = sum of the ECL ratios of the turbine building sump as determined by equation 6.1.

fl,2,3, 4 = effluent flow rate for radwaste, condensate demineralizer system andthe steam-generator blowdowns, respectively, gpm.

R1,2,3 = sum of ECL ratios for radwaste, condensate demineralizer system and the steam generator blowdowns, respectively, as determined by equation 6.1.

F = dilution flow rateforCTBD. The minimum assumed flow of 20,000 gpmwiltbe usedfor radwaste pre-release calculations.

6.1.3 Post-Release Analysis A post-release evaluation will be done using actual release data to ensure that the limits specified in ODCM Control 1.2.1.1 were not exceeded.

A composite list of concentrations (Ci), by nuclide, will be used with the actual waste flow (f) and dilution (F)flow rates (or volumes) during the release. The data will be evaluated to demonstrate compliance with-the limits in ODCM Control 1.2.1.1. [SOURCE NOTE 10]

6.2 INSTRUMENT SETPOINTS Liquid effluent monitor setpoints are determined to ensure that the concentration of.radioactiVe material released at any time from the site to UNRESTRICTED AREAS does not exceed ten times the ECL limits referenced in ODCM Control 1.2.1.1 and to identify any unplanned releases.

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 68;of 195 6.2.1 Process Discharge Point Monitor Setpoints (0-RE-90-133,-134,-140,-141)

The setpoints for the ERCW monitors (RE-90-133,-134,-140,-141) must ensure that the concentration of radioactive materials released at any time from the site do not exceed the limits given in ODCM Control 1.2.1.1. Since thiseffluent stream will not routinely contain, radioactivity, the setpointsfor-these monitors will be set at two times background to ensure thatany radioactivity is identified. Site procedures will document and control this value.

6.2.2 Release Point Monitor Setpoints (0-RE-90-122; O-RE,90-225; 0-RE-90-212; 1,2-RE&90-120A,-121)

The radiation monitor for batch release points, the Liquid Radwaste System and the Condensate Demineralizer System, monitors the undiluted waste streamas it comes out of a tank. The purpose of the monitor setpoints for these batch releases is to identify any, gamma-emitting release thats' lsarger than expected and would have the potential to exceed the limits after dilution. Setpoints are calculated as described by equations 6.3, 6.4, and 6.5 and may be set at a default value. Site procedures will document and control this value.

The continuous release points, the Steam Generator Blowdowns, and.the Turbine Building Sump, will notý be releasing gamma-emitting radioactivity unless there is or has beena primary to secondary leak. If this is the case, the continuous release points are monitored to identify~any gamma-emitting reiease that is larger than expected and would have the potential to exceed the ODCM Control 1.21.1. concentration limits after dilution. The monitor setpoints are calculated using Equations 6.3, 6.4, and 6.5 whenthis is the case. When these release points are being treated in this manner, a single release is defined'as all effluent released through this point on a continuous bases for a period of time (usually one week): During periods when there is no identified primary to secondary leak, these monitors are'set to _ 2 times background. Site procedures will document and control these setpoint-values.

For each release from a release point, two setpoints are calculated: one based on the monitor response to the contents of the effluent stream (as described below in Equation 6.4); and another based-onthe predicted response of the monitor to the activity in the release stream ifit were large enough to exceed ten times the 10 CFR 20 limits after dilution (as described below in Equation 6.5). .A comparison is made between these two calculated setpoints and the lower of the two is used'for the release. If default setpoints are used then a comparison is made between the two calculated setpoints and the default setpoint as described below to choose the appropriate setpoint for the monitor during the release (after the release, the monitor is normally returned to the defaultsetpoint).

1. If SER < Sdefault < Smax Reported = Sdefault
2. If SER < Smax < Sdefault Reported = SER
3. If SER > Smax Reported = Smax 6.2.2,1 Expected Response An expected response (ER) is calculated for the monitor for each release:

ER = BKG + Y,(Ei Ci) (6.3) where:

BKG = monitor background, cpm. The monitor's background is controlled .at an appropriate limit to ensure adequate sensitivity in accordance with site procedures.

Ei = monitor efficiency for nuclide i, cpm per IaCi/ml. This term may also be referred to as a response or calibration factor.

Ci, = tank concentration of nuclide i, pCi/ml.

El-130

WBN OFFSITEDOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 69 of 195 6.2.2.2 Expected Response Setpoint An expected response setpoint SER is calculated for the monitor for each release:

SER =X EiCI+X BKG (6.4) where:

X = administrative factors designed to account for expected variations in. monitor response and background (as defined in plant procedures). The ranges of values are: 0< X _2.0.

6.2.2.3 Calculated Maximum Monitor Setpoint A second setpoint is calculated for the release based on the predicted response of the monitor to the gamma-emitting activity in the release stream if it were large enough to exceed ODCM Control .1.2.1.1 limitsafter dilution. This setpoint ensures-that the release willbe stopped if it exceeds-thisjlimit. The maximum calculated setpoint calculation must satisfy the following relationship -from NUREG-0133:

sf (F+f) -

where:

C = the effluent concentration limit from 10 CFR 20 Appendix B, Table 2, Column 2, in gCi/ml, represented by a value of 1.

s = the setpoint, in pCi/ml, of the monitor measuring the radioactivity concentration inlthe effluent line prior to dilution and subsequent release. The setpoint, which is proportional to the -volumetric flow of the effluent line and inversely proportional to the volumetric flow ofthedilution stream, represents-a value which, if exceeded, would result in release concentrations exceeding the limits of ODCM Control 1.2.1.1 when the-effluent enters the Tennessee River.

f = the flow rate of the waste stream, gpm.

F = the dilution flow rate, gpm.

To determine the setpoint in cpm, If no dilution is available, then s < C.

Since C in the above equation represents the concentration equal to the limit, the setpoint s can be replaced by:

s= c. Dreq where

c. = the actual effluent concentration, pCi/ml.

Oreq = the required dilution factor.

E1-131

WBN OFFSITE DOSE CALCULATION MANUAL Revision, 22 0 (ODCM) Page 70 of 195 The required dilution can be defined as:

R Dreq" 10 SF where:

R = the sum of the ratios for gamma-emitting radionuclides, as~determined by equation 6.1.

10 = a value which implements the concentration limits of ODCMControl 1.2.1.1.

SF = a safety factor. The range of values for SF is: 0 < SF < 1.

Substituting ca Dreq into the above equation.for s, substituting 1 for C, and solving for ca:

10 SF (F+f) fR This value represents the amount that theexpected. response setpoint would be adjusted upward to account for the downstream dilution. For WBN, a portion of thetotal-dilution flow-is- allocated-to each release point using an-allocation factor (AF). To determine the maximum calculated monitor;setpoint, Smax, in cpm for a release point, the following equation is used:

Smax { OSF(f +(AF x F)) }(ER- BKG) + BKG (6.5) where:

AF = fraction of dilution flow allocated to this release point. For the TBS, AF= 0. The-fractions: for, the remaining 4 release points are normally defined as the ratio of the allocated CTBD flow .for that release point to the total CTBD flow. The CTBD flow allocation fractions for these release points are routinely:

Radwaste 0.6 Condensate demineralizer 0.2 Steam Generator Blowdown (U1) 0.1 Steam Generator Blowdown (U2) 0.1 These allocation factors may beadjusted for a~particular release if it is known that.there are no releases being made through other release points into the CTBD. For example, if there are no releases being made through the-Condensate Demineralizer or either SGBD, the AF for the Radwaste-System may be set equal to one.

ER = expected monitor response, cpm, as calculated in Equation. 6.3.

BKG = background, cpm.

WBN OFFSITE DOSE CALCULATION MANUAL Revision:22 0 (ODCM) Page 71 of 195 6.3 CUMULATIVE LIQUIDEFFLUENT DOSE CALCULATIONS Doses due to liquid effluents are calculated for each release for thefollowing;age. groups: adult.(17 years and older),.teen(11-17 years), child (1-11 years), infant (0-1 years) (Reference'4); and thefoIllowing organs: bone, liver, total body, thyroid, skin, kidney, lung, and Gltract.

Using the methodology presented in NUREG-0133, Section4.3, doses due to liquid effluents .are calculated for the ingestion of drinking water and freshwater fish consumption. Duelto the amount of recreation:along the TennesseeRiver, a dose for shoreline recreation is also calculated. This:, recreation dose is calculated by deriving a dose factor for use in the dose equation for the recreatioh path way using equations A-4 and A-6 in Regulatory Guide 1.109. Dose factors for these.three pathways are calculated as described in Section 6.7. For pathways with no age or organ specific dose factors (i.e.,, shoreline recreation), the total body dose will be added to the internal organ doses for all age groups. The consumption of freshwater invertebrates and consumption of food, crops irrigated with Tennessee River water are not considered significant pathways for the area surrounding WBN(References 9 and 10), s0 they are not considered in the dose calculations.

The maximum individual dose from drinking water is assumed to be that calculated at the' location immediately downstream from the diffuser. The maximum individualtdose from fish ingestion.is assumed to be that.calculated for the consumption of fish caught anywhere, between the plant and the'100% mixing point downstream(Table 6.1). The maximum potential recreation dose is calculated for a location immediately downstream of the plant outfall.

The general equation for the dose to an organ j is:

Dj =* ATCi D (6.6) where:

Aij =the total dose factor to the total body or any organ j for nuclide i,mrem/h per jgCi/ml. The total dose factor is the sum of the dose factors for water ingestion; fish ingestion, and shoreline recreation, as defined in Section 6.7.

T = the length. of time period over which the concentrations and the flows are averaged, h.

Ci = the average concentration of radionuclide i, in undiluted liquid effluent during the'time periodT from any liquid release, giCi/ml.

D = the near field averagedilution factorfor Ci during any effluent release. D is calculated bythe following equation:

- F 0.10 fx RF(67 (6.7) where:

f = maximum undiluted liquid waste flow during the release,.cfs. For TBS releases, this term is the waste flowinto the pond.

0.10 = mixing fraction of effluent in river, defined as the fraction of.the~riverflow which isavailable for dilution of the release (Reference 11).

RF = default riverfiow,.cfS: For each release, this value is setto 25,657 cfs (the~average quarterly riverflow recorded from the period 1985-94).

From the four age groups considered, the maximum organ dose is determined by comparing: all organ doses for all age.groups. The agegroup with the highest single organ dose: isselected as the critical age group. The total body and maximum organ doses for the critical age group are used~in the icalculation of the cumulative doses described in Section 6.3.1.

POPWTRj = water ingestion population dose to organ j, person-rem.

fPa = fraction of population in each age group a (from NUREG:CR-1004, table 3.39).

Adult = 0.665 Child = 0.168 Infant= 0.015 Teen = 0.153 POPm = population at. PWS m. The 3 PWSs and theirpopulations are listed in Table 6.1.

ATMWa = ratio of average to maximum water ingestion rates for each age group a. The values for maximum water ingestion rates are given as Uwa in Table 6.3. Average water ingestion rates, in L/y, (from Reference 4, Table E-4) are:

Adult = 370 Child = 260 Infant = 260 Teen = 260 TWDOSanj = total individual water ingestion dose to organ j at PWS m, to the age group a (calculated as described in Section 6.6.1), mrem.

10-3 = conversion factor for rem/mrem.

For population doses resulting from fish ingestion the calculation assumes that allfish caught within a 50-mile radius downstream of WBN are consumed by local population. The total fish harvest is calculated by multiplying the average fish harvest for the Tennessee River (HVST) by the size of the river reach under consideration (APR). These terms replace POPm. The general equation for calculating population doses, POPF, in person-rem from fish ingestion of all fish caught within a 50-mile radius downstream is:

(6.17) where:

POPFj = total fish ingestion population dose to organ j, person-rem.

HVST = fish harvest for the Tennessee River, 3.04 lbs/acre/y edible weight (Reference 12).

APR = size of reach, acres (Table,6.1).

TFDOSari = total fish ingestion dose to organ j for reach r, for the age group a, (calculated as described in Section 6.6.2), mrem.

fPa = fraction of population in each age group a, as given above.

FISHa = amount of-fish ingested by each age group a, kg/y. Average fish ingestion rates, kg/y (Reference 4, Table E-4) are:

Adult = 6.9 Child = 2.2 Teen = 5.2 Infant = 0.0 E1-139

For shoreline recreation, the total recreation dose is determined by multiplying the-average dose rate (TSHDOS) to an individual by the number of visits to that.river reach (SHVIS) and~the'length ofthe average visit (HRSVIS). The general equation used for calculating the population doses, POPR, in person-rem is:

rf 4 POPRj = 1 8 TSHDOSrj SHVISr HRSVISr (6.18) 103 8760 r=1 where:

POPRj = total recreation population dose for all reaches to organ j, person-rem.,

rf = fraction of,;yearly recreation which occurs in that quarter, as given-in Section, 6.63.

TSHDOSrj = total shoreline dose rate for organ j, in reach r, mrem/h.

SHVISr = shoreline visits per year at each reach r, (Table 6.1-).

A11 = +ow UFB +UFBFIjJ)DFi where:

k0 = conversion factors.

Uw = water consumption rate, L/y.

Dw = dilution factor from the near field area within one-quarter mile of the release point to the potable water intake for water. consumption, dimensionless.

UF = fish consumption rate, kg/y.

BFi = bioaccumulation factor for nuclide i in freshwater fish, pCi/kg per pCi/L.

U, = invertebrate consumption rate, kg/y.

DFi = ingestiondose conversion factor, mrem/pCi.

Since the value of the: term. Ui. is negligible, WBN will not be considering the.dose from invertebrate ingestion and thatportion ofthe equation isdropped. In addition, a term is addedjto account for recreation. The near-field dilution factor is assigned a value of 1 in the water ingestion portion of the equation and is not used for WBN due to the use of riverflow as the dilution factor in the dose calculation.

The resulting general dosefactor equation is:

Aij = ko (Uw +UF BFi)DFi +kl UR Cs DFGi where:

k0,1 = conversion factors.

UR = recreation usage factor, h/y.

Cs = accumulation factor for buildup of activity in sediment, pCi/in 2 per,pCi/L.

DFGi = dose factor for standing on contaminated ground, mrem/h per pCi/m 2.

WBN OFFSITE DOSE CALCULATION MANUAL Revision,22 0 (ODCM) Page, 101 of 195, 7.0 - GASEOUS EFFLUENTS INTRODUCTION There are six discharge points for gaseous radioactive effluents from WBN. These dischargepoints are:

Unit 1 Condenser Vacuum Exhaust (CVE), Unit 2 CVE, Service Building Exhaust., Auxiliary Building Exhaust, Unit 1 Shield Building Exhaust,- and Unit 2 Shield Building Exhaust. Detailed descriptions are provided below, and Figure 7.1 provides an outline of these airborne dischargepoints with associated radiation monitors. None of these discharge points meets the criteria of Regulatory Guide 1.111 for elevated releases; therefore, all releases are considered to be ground-level. Various plant systems contribute activity to the CVE, the Service Building Exhaust and the Auxiliary Building Exhaust, but these sources are not treated as individual release points. There are two gas systems associated with each Shield Building Exhaust: the Waste Gas Decay Tank (WGDT) System and the Containment*lPUrge System which includes the Incore Instrument Room Purge.

The discharge points and the two associated gas systems are each monitored by noble gas radiation monitors. These monitors perform two main functions: to identify any unexpected radioactivity releases, and to ensure that the dose rate limits of ODCM Control 1.2.2.1 are met. Each monitor has an alarm/trip setpoint which causes the monitor to alarm if the monitor's setpoint is exceeded. The;monitors do not have separate alarm and trip setpoints; they have one setpoint which performs. both functions. The noble gas radiation monitors for Containment Purge and the WGDT release points initiate an isolation function if the alarm/trip setpointis exceeded. The radiation monitor alarm/trip setpoints foreach release point and discharge point are based on the radioactive noble gases in the gaseous effluent. It is not~considered practical to apply instantaneous alarm/trip setpoints for integrating radiation monitors sensitive to radioiodines, radioactive materials in particulate form, and radionuclides other than noble gases.

Releases are continuous, except for releases from the WGDT or Containment Purge Systems which are made as batch releases.

For batch releases, the WGDT or Containment to be released is grab sampled for radioactivity in accordance with Table 2.2-2. The samples are analyzed to determine the maximum allowable release flow rate to ensure compliance with the dose rate limits of ODCM Control 1.2.2.1 as described in ODCM Section 7.2. The sampling results are also used to determine a setpoint for the associated noble gas radiation monitor for the release. The setpoints are determined in accordance with ODCM Section 7.1.

Dose calculations are performed for each release, as outlined in ODCM Sections 7:3 and 7.4, to determine compliance with ODCM Controls 1.2.2.2 and 1.2.2.3.

For continuous releases, the pathways are sampled for radioactivity periodically, as required by Table 2.2-2. The samples are analyzed to ensure compliance with the dose and dose rate limits of ODCM Control 1.2.2.1, 1.2.2.2, and 1.2.2.3, as described in ODCM Sections 7.1 and 7.2. The sampling results are also used to determine a setpoint for the associated noble gas radiation ,monitor for the release. The setpoints are determined in accordance with ODCM Section 7.1. Dose calculations are performed for each sampling period, as outlined in ODCM Sections 7.3 and 7.4, to determine compliance with ODCM Controls 1.2.2.2 and 1.2.2.3.

Once per month, the projected dose is calculated, as outlined in ODCM Section 7.5,. to determine compliance with ODCM Control 1.2.2.4.

The calculational methodologies are based on the guidance provided in NUREG-0133 andRegulatory Guide 1.109. Because all releases aregroundrlevel, semiý-

infinite cloud models are used.in the dose calculations.

The quantities of each radionuclide identified and released are input into a more rigorous calculation methodology, described inODCM Section 7.7, to determine the individual and population doses'to be reported to the NRC in the Annual Radioactive Effluent Release Report. These dose. calculation methodologies are based on the guidance provided in Regulatory Guide 1.109.

RELEASE/DISCHARGE POINTS DESCRIPTION There are six discharge points at WBN that are monitored for airborne, radioactive effluents. These are:

a CVE for reach unit, ýa Service Building Exhaust, an Auxiliary Building Exhaust and a Shield Building Exhaust for each unit. Each of these discharge points may have oneor more release points associated with it as described below. Figure 7.1 provides a simplified outline of the airborne effluent release and dischargepoints with associated radiation monitor identifications. Figure 7.2. provides a more detailed description of the release and discharge points, with flow rates, radiation monitors, and associated inputs.

Condenser Vacuum Exhaust The CVEs are located in the turbine building. They exhaust at a maximum design flow rate of 45 cfm per pump. These discharge points are monitored by radiation monitors 1,2-RE-90-119 for normal operation.

Service Buildina Exhaust Areas in.the Service Building in which work is conducted which may produce radioactive effluents all exhaust to.the Service Building Exhaust. This discharge point exhausts at a. maximum design flow rate of approximately 10,000 cfm and is monitored by radiation monitor 0-RE-90-132B.

Auxiliary Buildinaq Exhaust The Auxiliary Building exhausts at a maximum total design flow of.228,000-cfm (2 of 4 ventilation fans and 1 fuel handling fan). This discharge point exhaust is monitored by radiation monitor,0-RE-90-I01B.

The annulus vacuum priming fans (2 fans at 1000 cfm each) exhaust to the auxiliary building fuel handling exhaust header.

Shield Building Exhaust There is one Shield Building Exhaust for each unit. These discharge points are monitored by- radiation monitors 1,2-RE-90-400A.

There are nine Waste Gas.Decay Tanks (WGDTs) that discharge into the waste gas header which is released into the Unit 1 Shield Building Vent (see Figure 7.3). The Train A Auxiliary Building Gas TreatmentSystem (ABGTS) is operated during a WGDT release. EachWGDT hasa design capacity of 600 ft 3 and a maximum design release rate of 100 cfm [SOURCE NOTE 17]. The WGDT release point is monitored by radiation monitor 0-RE-90-118.

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page .1103of 195 The Auxiliary Building Gas Treatment System (ABGTS) draws from theAuxiliar BuidingSecondary Containment Enclosure andexhausts to the Shield Building Exhaust. Any activity-releasedifrom the Auxiliary Building through theABGTS is accounted for as a. part of the Auxiliary.Building Exhaust releases, and will not be tracked separately. An Auxiliary Building Isolation signal starts'.the ABGTS.

The Emergency GasTreatment System:is used to draw a vacuum in the annulus and exhaust to the Shield Building Exhaust under emergency conditions, and coulddo so during normal operation.

Both the Containment Purge and the. Incore Instrument Room-Purge from each unit tie into the Shield Building Exhaust.. The Containment Purge release pointexhausts at a maximum of 28;000 cfrm and is monitored by radiation monitors 1,2-RE&90-130 and 1,27,RE-90-131. If the Incore Instrument Room Purge is operating exclusively, it~exhausts at 800 cfm, and is monitored by the Containment PurgeMonitors given above. The common header exhausts to the Shield Building Exhaust.

7.1 GASEOUS EFFLUENT.MONITOR INSTRUMENT SETPOINTS Airborne effluent noble gas monitor setpoints are determined toensure that the d6se rate at the UNRESTRICTED AREA BOUNDARY does not exceed the dose rate limits given.,in.ODCM Control 1.2.2.1 and to0identify unexpected releases. ODCM Control 1'.1.2 establishes operabilityi requirements for these .monitors. Allocation factors (AF) are used in. the setpoint calculation to allocatea fraction of the total body, dose rate limit to, each discharge point. These allocationlfactors may be changed,,as required to support plant operational needs, but shall not exceed asum of one.' Therefore, a particularfmonitor reaching the calculated maximum setpoint as described below-does not necessarily mean thatI thedose rate limit at-the UNRESTRICTED AREA BOUNDARY is being.exceeded; the alarm indicates that:the specific release/discharge point is contributing a greater fraction of the dose rate limit thanwas allocated to the associated monitor and will require further evaluation.

The gaseous effluent radiation monitors and their setpoint information are outlined-below:

During periods of release, the methodology in Section 7.1.2 will be usedto determine-the monitor setpoint and may be set at a default value. Site procedures will document and control this value.

7.1.1.3 Shield Building Exhaust (1,2-RE-90-400A), AuxiliaryBuildingExhaust(0-RE-90-101 B),

Containment Purge Effluent Monitors (1,2RE-90-130:,-131), and Service Building Exhaust (0-RE-90-132B)

These discharge point effluent monitors are set to ensure compliance with ODCM Control 1.2.2.1.

The default setpoints aredetermined by calculating the maximum calculated setpoint described by Equation 7.3 using Xe-1 33 monitor efficiencies, design flow rates, and setting the ýratio DRuim/DR equal to 1.0. The default setppints.for the shield building monitors are calculated in units of gCi/s. The default setpoints will be defined in plant procedures.

7.1.1.4 Condenser Vacuum Exhaust Vent (1,2-RE-90-119)

This discharge point effluent monitor is set to ensure compliance with ODCM Control 1.2.2.1 and to identify the presence of primary to secondary leakage of radioactivity. The default setpoint is determined in one of two ways: by calculating the maximum calculated Setpoiht as described in Section 7.1 .1.3, and then taking a percentage of this value as the setpoint; or by defining the setpointas two times thenormal background. The default setpoint will be defined in plant instructions. Once a primary to'secondary leak is identified, the setpoint on this monitor may be incrementally adjusted upward as defined in plant procedures to enable it to be used to identify any further increases in the leak rate.

7.1.2 Release Permit Monitor Setpoint Determination For each release, two setpoints are calculated for the monitor: one based on the expected response of the monitor to the radioactivity in the effluent stream (described in Sections.71 ;2.1and 7:1.22) Which allows for the identification of any release of radioactivity above the expected amount; and a calculated maximum setpoint which corresponds to the most restrictive dose rate limit given in ODCM Control 1.2.2.1 (described in Section 7.1.2.3) which ensures that the release will be stopped if it exceeds the dose rate limits after dilution. A comparison is then made (as described in Section 7.1:2.4) between these two calculated setpoints and the default setpoints (described in Section 7.1.1) to determine which is used for the release.

D = JAQi R1 i +.LQi i i RGi +I*Qi Rp1 P

Since the calculation of tritium concentration in vegetation is based on air concentration rather than ground' deposition (Equation C-9 in Regulatory Guide 1.109), a separate term is added to~the equation to account'for the tritium ingestion dose pathways. In addition, a terrain adjustmentfactor (TAF) is added.

Therefore the equation for calculating the organ dose, Dj in mrem, is:

QT = adjusted release rate for tritium for location under consideration, IaCi/s. The. initial release rate:is adjusted to account for. decay between the release pointand the location, depending on the frequency of wind speeds applicable to that sector. Hence, the adjusted. release rate is equal-to the actual release rate decayed for an average travel time during the period.

pasture grass-beef ingestion - RMp (see Section 7.8.3).

stored feed-beef ingestion - RMS (see Section 7.8.4).

RGi = Dose factor for standing on contaminated ground, m2-mrem/y per ICi/s. The equation for calculating theground plane dose factor is given in Section 7.8.14.

X/Q = Relative concentration for location under consideration, s/m 3. Relativeconcentrations are-calculated as described by Equation 7.34.

Qi = adjusted release rate for nuclide i for location under consideration, gCi/s. Calculated in the same manner as QT above.

The highest organ dose for a real receptor is determined by summing thedose contributionfrorm all identified pathways for each receptor including ground contamination, inhalation,, vegetable ingestion: (for identified garden locations), cow and/or goat milk ingestion (if a cow or goat is identifiedifor the location),

beef ingestion (the beef ingestion dose for the location of highest beef dose for all receptors will be considered the beef dose for all receptors).

7.7.4 Population Doses The population dose is determined using Equation D-1 from Regulatory Guide 1.109:

D = k Y POPm Y. Daij FPma m

For determining population doses to the 50-mile population around the plant, each compass sector is broken down into elements. These elements are defined in Table 7T5. Dispersion factors;are calculated for the midpoint of each sector element (see Table 7.5). For each of these sector elements, an iaverage dose is calculated, and'then multiplied by the population in that sector element. The average dose is determined by multiplying the maximum individual dose for the sector by the ratio of the: average tothe maximum usage rates. For population doses resulting from~ingestion,.itis conservatively assumed that all foodeaten by the average individual is grown within the sector element. The-general equation used for calculating the population dose in a given sector element is:

Dosepop = 0.001 ERATIOp POPm FPa DOSEp P

where:

0.001 = conversion from mrem to rem.

RATIOp = ratio of average to maximum dose for pathway P. Maximum ingestion rates are given in Table 6.3. (Average ingestion rates are obtained from Reference 4, Table E-4.)

= 0.5 for submersion and ground exposure pathways, a shielding/occupancy factor..

= 0.515, 0.515, 0.5, and 0.355 for milk, for infant, child, teen and adult,: respectively. (Itis assumed that the-ratio of average to maximum infant milk ingestion rates is:the same as that for child.)

= 1.0, 0.38, 0.38, 0.37 for vegetable ingestion, for infant, child, teen and'adult, respectively. (It is assumed that the average individual eats no fresh leafy vegetables, only stored vegetables.)

POPm = the population of the sector element m, persons (Table 7.6).

FPa = fraction of the population belonging to each age group.

= 0.015, 0.168, 0.153, 0.665 for infant, child, teen and adult, respectively (fractions taken from Reference 21, Table,3.39).

DOSEp = the dose for.pathway P to.the maximum individual at the location underconsideration,tmrem (as described in:Sections 7.7.1, 7.7.2, and 7*7.3). For ingestion pathways, this dose is

-multiplied, by an average decay correction to account for decay as thefood is moved through the food distribution cycle. This average decay correction; ADC, is defined as follows:

For milk and vegetables:

ADC = exp(-,itd) (7.17)

For beef:

ADC = exp(-Xitd) Xitcb (7.18) 1- exp(-XitCb) where:

i= decay constant for nuclide i, s1.

td = distribution time for food product under consideration (values from Reference 4, Table D-1).

= 1-21 E+06 s (14 d) for vegetables.

= 3.46E+05 s (4 d) for milk.

= 7d for beef tcb = time to consume a whole beef, as described in Section 7.8.3.

For beef ingestion, the additional .factors in the calculation of ADC negate the integration of the dose term over the period during Which a whole beef is consumed, for the calculationof population dose. Inother words, this assumes that the maximum individual freezes and eats a whole beef, while the-average individual buys smaller portions.at.a time.

Population doses are summed over all sector elements to obtain a total population dose for the 50-mile population.

7.7.5 Reporting of Doses The calculated quarterly doses and calculated population doses described inSection,7.7 are reported in the Annual Radioactive Effluent Release Report as required by ODCM Administrative Control 5.2.

This basis also states that examples:of calculations for such MEMBERS'OF THE PUBLIC will be given in the ODCM.

Calculations are presented in Section 12.4 of the WBN UFSAR which estimate the annual doses-at the boundary of the restricted area (WBN UFSAR Table 12.4-2)ý The total dose rate is'thesufriof the adult whole body inhalation dose~rate, the gamma dose ratefrom the plume and:ground contamination, and the gamma dose rate from outdoor storage tanks. As indicated in the UFSAR, the highest total dose, rate at the boundary of the restricted area is 105 mremly, based on a continuous 2000.h/y Occupancy. Use of a more realistic occupancy, reflective of the transient traffic expected for this location, would result in a much lower dose estimate. It is, therefore, considered highly unlikelythat a member of the public would receive greater than 100'mrem/y at Orbeyond the restricted:area boundary.

In addition to this calculation, .the dose to these MEMBERS OF THE PUBLIC (obtained'from dosimeters deployed at the Restricted: Area Boundaryand from estimates of the dose from gaseous effluents) will' be reviewed on' an annual basis to ensure that the actual exposure to any indi viduals is less'.than-i00 mrem/y for these locations. The results of this review will be included 'in'the Annual' Radiological Effluent Report pursuant to ODCM Administrative Control 5.2.

A sector-average dispersion equation consistent with Regulatory Guide 1.111 is used. The dispersion model considers plume depletion (using information from Figure 7.4), and building wake effects. Terrain effects on dispersion are considered as described in Section 7.9.4.

Hourly average meteorological'data are expressed as a joint-frequency distributionof wind speed, wind direction, and atmospheric stability. The joint-frequency distribution which represents thethistorical meteorological data for the period January 1986 to December 2005 is given in Table 7.2.

The wind speed classes that are used are as follows:

Number Range,(m/s)1 Midpoint,(m/s) 1 <0.3 0.13 2 0.3-0.6 0.45 3, 0.7-1.5 1.10 4 1.6-2.4 1.99 5 2.5-3.3 2.88 6 3.4-5.5 4.45 7 5.6-8.2 6.91 8 8.3-10.9 9.59 9 >10.9 10.95 The stability classes that will be used are the standard Pasquill A through G classifications.

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 134o6f 195 7.9.4 Terrain Adjustment Factor - TAF As discussed in Reference,5, the straight-line dispersion model does not account for spatial andtemporal variations in the airflow expected from the southwest-northeast aligned'river valley. Such variations are considered by application of site-specific terrain adjustment factors, TAF. These factors were developed through the comparison of variable trajectory model results with straight-line model results for onIsite meteorological data for 1978 (Reference 19). The ratio of the variable trajectory model[dispersion factors to the straight-line model dispersion factors is defined as the TAF.

The dispersion factors used in the dose rate and dose calculations described in Sections 7.2.2, 7.2.3, 7.3.1, 7.3.2, and. 7.4.1 are calculated using the meteorological data from the 1986 to 2005 period (in Table 7.2).

.XIQ and D/Q values are calculated for each of the 16 UNRESTRICTED.AREABOUNDARY sector locations (Table 7.1). Theseare multiplied by the TAF associated with each of these sectors (see Table 7.3). The highest of these dispersion values are chosen for the dose or dose ratecalculations.

The dispersion factors used in the dose calculations described in Section 7.7 are calculated using the: actual meteorological data for the :period. X/Q or D/Q values are calculated using Equations 7.34 and 7.35 for the unrestricted areaboundary:locations identified in Table 7.1, for the 16 nearest resident locations, and all garden and milk animal locations identified in the annual land use censu's described in Section 9.3. The TAF values associated with these dispersion factors is the ratio of the dispersion factor calculatedbythe variable trajectory model to that calculated by the straight-line model for each of these locations using the 1978 meteorological data. These values will be calculated for all locations identified by the land, usecensus and then used to modify the -IQ and D/Q values determined with the actual meteorologicaldata: Any TAF values of less than 1.0 will be defined as 1.0.

The annual doseto the maximum individual will be conservatively estimated by using the following equation:

4 D = S D(airtb) + D(airorg) + D(liqtb) + D(liqorg) + D(direct) (8.1) q=1 where:

q = calendar quarter D(airtb) = the total body air submersion dose (as calculated in Section 7.7)

D(airorg)= the critical organ dose from gaseous effluents (as calculated in Section 7.7),

D(liqtb) = the total body dose from liquid effluents (as calculated-in Section 6.6.4),

D(liqorg) = the critical organdose from liquid effluents(ascalculated in Section. 6;6.4),

D(direct) = the directradiation dose measured by the environmental monitoring program.

The dose calculated is compared to the total body/organ limit of 25 mrem. If the dose is greater than 25 mrem, then the dose to each individual organ will be evaluated separately for comparison to the limits.

WBN OFFSITE DOSE CALCULATION: MANUAL Revision,22 0 (ODCM) Page 162 of 195 9.0 - RADIOLOGICAL ENVIRONMENTAL MONITORING PROGRAM (REMP) 9.1 MONITORING PROGRAM DESCRIPTION The REMP shall be conducted in accordance with the requirements of ODCM Control 1.3:1. The monitoring program described in Tables 9.1, 9.2, and 9.3, and in Figures 9:1, 9.2 and 9.3 shallbe conducted.

The program consists.of 3 major sections corresponding to the atmospheric pathway, the terrestrial pathway, and thewaterborne.pathway. In the atmospheric monitoring program, samples of air particulates and atmospheric radioiodines are collected from established stations. The stations are identifiedas Local Monitor (LM) stations, located at or near the unrestricted area boundary; Perimeter Monitor (PM) stations, located typically3-10 miles from the site; and Remote Monitor (RM) stations, located greater than 10 miles from the site, The remote monitors areconsidered as, background or control stations.

The terrestrial monitoring program includes the collection of milk, soil, and food crops. In addition, direct gamma radiation levels will be measured in the vicinity of the plant.

The waterborne monitoring program consists of the collection of samples of surface and ground water; drinking water, sediment, and fish. Samples are collectedboth downstream and upstream from .the plant site.

The basic description of the.REMP is included in Tables 9.1 and 9.2. Table 9.3 describes the'locations of the direct gamma radiation detectors (dosimeter). Figures 9.1, 9.2, and 9.3 show'theilocations of the stations within one mile of the site, between one and five miles from the site, and greater than'5 miles from the site, respectively.

Deviations are permitted from the required sampling schedule if specimens are.unobtainabledue~to hazardous conditions, sample unavailability, or malfunction of sampling eqUipment. If-the latter;, every effort shall be made to complete corrective action prior to the end of the nextsampling period. Deviations from the required program will be reported in the Annual Radiological Environmental Operating Report in accordance with the provisions of ODCM Control 1.3.1.a and AdministratiVe Control 5.1. Changes made in the program resulting from unavailability of samples will be reported in accordance with ODCM Control 1.3.1.c.

9.2 DETECTION CAPABILITIES Analytical techniques shall be such that the detection capabilities listed in Table 2.3-3 are'achieved.

9.3 LAND USE CENSUS A land use survey shall be conducted in accordance with the requirementsgiven in ODCM Control 1.3.2.

The results of the survey shallbe reported -inthe Annual Radiological Environmental Operating Report.

Changes made in the REMPas a result of the Land Use'Census will be reported in accordance with the provisions of ODCM Control 1.3.2.b.

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 163 of 195 9.4 INTERLABORATORY COMPARISON PROGRAM Analyses shall be performed on radioactive materials supplied as part of an Inter!aboratory Comparison Program which has been approved by the NRC. A summary of the results obtained ih the intercomparison shall be included in the Annual Radiological Environmental Operating Report '(or the EPA program code designation may be provided).

If analyses are not performed as required corrective actions taken to prevent a recurrence shall be reported in the Annual Radiological Environmental Operating Report.

9.5 DATA REVIEW AND REPORTING Results of this program shall be reported inaccordance with ODCM Administrative Control. 5ý1,Annual Radiological Environmental'Monitoring Report. Analytical, results exceeding the reporting levels outlined in ODCM'Table 2.3-2 will be reported in accordance with the requirements of ODCM Control. 1"3.1..b. As noted in WBN FSAR Section 11.6, routine releases from WBN will result in environmental, concentrations well below, the detection limits for environmental media, making correlations between calculated, effluent' release dataand environmental measurements impractical. Onlyif radioactive releases from the site result in statistically measurable increases in environmental levels candosecorrelations be made.

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 185 of 195 APPENDIX B - Deviations, in the WBN ODCM Controls/Surveillance Requirements from Those Given in NUREG-13016 (Page 1 of 4)

1. Controls 1.0.1 and 1.0.2 and Surveillance Requirements 2.0.1-2.0.4 have been replaced by the, most recent WBN LCOs3.0.1 and3.0.2 and SRs 3.0.1-3.0.4. This has been done toensure consistency between the WBN TS and the WBN ODCM.
2. Control 1/2.1.1 NUREG-1 301 does not list the applicability for liquid monitoring instrumentation.

Applicability for WBN liquid effluent instrumentation is defined in Table 1.1-1to match the requirements provided in the ACTION statements associated with the table.

Table 2.1 Channel calibration for the Diffuser Discharge Flow Indicator is, changed to yearly due to requirements in the NPDES permit. This is more conservativethan required by'NUREG&1301.

Table 2.1 The Channel Operational Test Frequency for items 3.a (Radwaste Flow), 3.b (Steam GeneratorBlowdown Flow), and 3.c (Condensate Demineralizer Flow) are N/A. These items do not have an associated alarm, interlock, and/or trip setpoint, therefore a Channel Operational Test cannot be performed'for-these items.

Table 2.1 Footnote 1"is deleted from Items 1.b (Steam Generator BlowdownRadiation) and: 1.c (Condensate Demineralizer radiation). Item 1.b and 1.c generate an automatic isolation on level above the alarm/trip setpoint, not instrument malfunction.

Table 2.1 The circuit failure test associated with the channel operational test (COT) has been deleted. By definition a COT verifies the channel can process an input signal and actuate output devices and that there are no circuit failures that impact the required.functions. The notes in Tables 2.1-2 which supplement the COT definition require tests to verify operation of specific features that alert the operator of a malfunction. These include downscale failure (loss of counts), controls not in operate mode (switch mispositioned), and loss of sample flow. Circuit failure could be caused by any number of subcomponent failures. There is not a specific circuit that, is monitoring for each of those subcomponent failures.

3. Control 1/2.1.2 - Table 1.1 -2 limits. operability for WGDT release instrumentation to'periods.of release.

Table 1.1 Includes operability requirements for heat trace on iodine/particulate sampleliries for Condenser Vacuum Exhaust and Shield Building Exhaust.

Tables 1.1-2 and 2.1-2'require that both Unit 1 and 2 Shield Building Exhaust monitors must meet operability requirements to operate either unit. This is because releases through the ABGTS may exit from either unit's Shield Building Vent.

Table 1.1 Wording is added to clarify the Shield Building Vent monitor noble gas channel operability requirements. This monitor has the capability to read in units of gCi/cc or RCi/s, The usual channel will read in gCi/s, but this wording allows the monitor to be switched to read in gCi/cc if the flow channel becomes inoperable to eliminate the need for compensatory samples.

Table 1.1 The Applicability for Items 2.a, c, and d (Condenser Vacuum Exhaust (CVE) radiation monitors and flow instruments) is MODES 1, 2, 3, and 4 and duringMODES 5 and 6 with CVE System in operation. The radiation monitoring instrumentation does not have to be operable if the Exhaust system is not in operation.

Table 1.1 Items 3.f and 4.e were added as part of the changes associated with operating with a TPBAR core.

Table 2.1 Includes surveillance requirements for heat trace on iodine/particulate sample lines for Condenser Vacuum Exhaust and Shield'Building Exhaust.

Table 2.1 The channeloperational test frequency for 3.b (Shield Building Exhaust Iodine and Particulate Sampler), and 4.b (Auxiliary Building Exhaust Iodine and'Particulate Sampler)of Table 2.1-2 are N/A. These items have no associated alarm, interlock, and/or trip setpoint, therefore a Channel Operational Test cannot be performed.

WBN OFFSITE DOSE CALCULATION MANUAL Revision 22 0 (ODCM) Page 186 of195 APPENDIX B - Deviations in the WBN ODCM Controls/Surveillance Requirements from Those Given in NUREG-1301 (Page 2 of 4)

Table 2.1 The channel check requirements for all iodine and particulate samplers are N/A. The channel check requirement is intended to demonstrate that the sampler is operable. An indication of flow through the sampler verifies its operability. The daily channel checkfor the sampler flow(s) and the weekly sampler filter changeout required by the sampling and analysis program in"Table 2.2-2 provide this indication of operability, therefore a channel check requirement inthis Table is redundant.

Table 2.1 The circuit failure test associated with the channelroperational test ,(COT) has been deleted. By definition a COT verifies the channel can process an input signal and actuate output devices and that there are no circuitfailures that impact~the required functions. The notes in Tables 2.1-2 which supplement the COT definition require tests to verify operation of specific features that alert the operator of a malfunction. These include downscale failure (loss of counts), controls not in operate mode (switch mispositioned), and loss of sampleflow. Circuit failure could'be caused by any number of subcomponent failures. There is not a specific circuit that is monitoring for each of'those subcomponent failures.

4. Control 1/2.1.3 is added to place the meteorological monitoring requirements in the ODCM.
5. Control 1/2.2.1.1 - Table 2.2-1, the requirements for samplingof continuous liquid release pathways (TBS and SGBD) are for daily grab samples rather than a continuous sampler. This is consistent with the requirements for SQN for the same points. The definition of a composite liquid effluent sample is somewhat different than that given in NUREG-1301 (WBN will be creating the composite in the lab from the grab samples, the NUREG is referring to a composite sample from a continuous sampler).

The analyses for these daily grab samples are daily, rather than weekly. Each sample will be analyzed, rather than compositing the samples for the week.

Table 2.2 Footnote 6 is added to require that the continuous liquid release points be sampled only if primary to secondary leakage is identified, and either the monitor must be set to two times background OR compensatory samples are being collected. This is consistent with requirements in the SQN effluent controlprogram. The activity determination is clarified to state-thatprincipal gamma emitters will be used for the determination.

6. Control 1/2.2.2.1:

Table 2.2-2 is reformatted from the NUREG version to place more of the requirements in the table itself, and eliminate some of the footnotes. This allows easier implementation of the sampling requirements in plant procedures.

a. Table 2.2-2 requires sampling of containment purge and vent following shutdown, startup;, or a thermal power change exceeding 15% of RATED THERMAL POWERwithin a 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> period. This is consistent with the NUREG, but WBN goes further to. state that this does not need to be done if.

analysis shows that-the DEl has not increased by a factor of 3 or more, AND if.the lower containment noble gas monitor does not show an increase of a factor of 3 or more. This is Consistent with the requirements in the SQN effluent control program.

b. Table 2.2-2, Footnote 8 details applicability and timing requirements for sampling of the containment for purges. This note is consistent with one in the SQN ODCM, except that MODE'requirements and times are different.
c. Table 2.2-2, Footnote 8 details applicability and timing requirements for sampling for incore instrument room purges. This note is consistent with one in the SQN ODCM, except that MODE requirements and times are different.
c. Table 2.2-2, Footnote 10 details applicability requirements for sampling of the containment for venting.

This note is consistent with one in the SQN ODCM, butdetails are different.

d. Table 2.2-2, the Shield Building Exhaust is excluded from the monthly requirement for grab sampling. to analyze for noble gas and tritium, since all releases through this point will havebeen quantified previously.
e. Table 2.2-2, Footnote 11 excludes the Condenser Vacuum Exhaust from the requirementsfor sampling until, a primary. to secondary leak is identified. The activity determination is clarified to state that principal gamma emitters will be used for the determination.
f. Table 2.2-2, the table limits:theprincipal gamma emitters for.grab samples to the noble gas,.nuclides to clarify that particulate releases are quantified from filter analyses.
g. Table 2.2 Footnotes 3 and 7 allow compensatory grab samples to be used to determine if activity levels have increased during periods of radiation monitor inoperability..
h. Table 2.2 Requirements for continuous tritium sampling were'added for the Auxiliary Building Exhaust and Shield Building Exhaust to quantify releases during1he irradiation and storage of, TPBARs. Since tritium samples willbe collected continuously footnotes 4-and 5, which required tritium grab samples, were removed.' The use of continuous tritium samplers provides a more accurate account of the tritium released than grab samples.
i. Footnotes 8 and 10 clarifies that only the containment compartment to be released, needs to be sampled. This.will eliminate unnecessary sampling.
j. Table 2.22- Priorlto release each Waste Gas Decay Tank will require tritium analysis aspart~as the changes associated with operating with a TPBAR core.
7. Control 1/2.3.1:
a. Table 2.3 the drinking water control sample location is defined in footnote 9 to: be the Upstream surface-water sample.
b. Requirementsfor drinking water sample analysis differ from the NUREG. Due to-the large downstream distance of the first public water supply (> 10 miles) and the volume of dildtion water available, doses due to water ingestion will be Very low under normal circumstances. This situation applies at both SQN andBFN and is reflected in their Environmental.Monitoring Programs.
c. Text is added toTable 2.3-1 footnote 8 to state that the hydraulic gradient of the.groundwater at the WBN site is'such that the groundwater will move from the site toward the ýriver, therefore groundwater sampling is not required.
d. Table 2.3-1 footnote 3 is added to clarify identification of control samples for iodine and particulate airborne monitoring.
e. Table 2.3ý1, The invertebrate sampling requirements have been relocated to the waterbome section of theTable to more accurately reflect the purpose of these samples. Thereis negligible ihgestion of invertebrates from the Tennessee River.
8. BASES 1/2.1.3 - Bases for the meteorological monitoring instrumentation Control are in the IODCM.
9. BASES 1/2.2.1.1 - An additional reference is given for further LLDdiscussion (ARH-SA-215, June 1975). Allocation of activity between the reactor units for dose calculation purposes is discussed in more detail.
10. BASES 1/2.2.1.2 - Text is added to explain that the dose for composited nuclideswill be calculated using the values from theprevious compositing period.
11. BASES 1/2.2.1.4 Allocation of activity between the reactor units for dose calculation purposes is discussed in more detail.

12. BASES 1/2.2.2.1 An additional reference is given for further LLD discussion (ARH-SA-215, June 1975). Allocation of activity between the reactor units fordose calculation purposes is discussed in more detail.
13. BASES 1/2.2.2.2 and 1/2.2.2,4 Allocation of activity between the reactor units for dose calculation purposes is discussed in more detail.
14. BASES 1/2.3.1 An additional reference is given for further LLD discussion (ARH-SA-215, June 1975).
15. The definitions of Member of the Public and Restricted area are not consistent with those given in NUREG-1301. This is due to the revision to 10 CFR 20 implemented by TVA on 1/1194. The definitions are consistent with that regulation. Similar changes are made to theBASES sections to clarify the wording where these definitions are used. Figure 3.1 shows.the locations of these boundaries and areas. A calculation is given in Section 7.7.6*for a member of;the public inside the.

Site Boundary demonstrating that the location of the unrestricted area. boundary on the opposite side of the Tennessee River.meets the intent of the regulation.

16. The Source Check definition' is changed to reflect changes made in the definition, for SQN (revision 27). The new definition will allow the use of internal test circuits' in:lieu of a radioactive source (some monitors use anLED light source to provide the check signal to the photomultiplier tube).
17. The Operational ModesTable (Table 3.2) is consistent with the WBN TS.

1.0 INTRODUCTION

1.1 PURPOSE The purpose of the Watts Bar Nuclear Plant (WBN):Process ControlIProgram (PCP) is to establish a program which provides reasonable assurance that all radioactive wastes processed at WBN for disposal at a land disposal facility are processed and packaged such that applicable Federal and State regulations and disposal site criteria are satisfied. The PCP contains a general description of the methods for controlling the processing and packaging of radioactive wastes, specific parameters for each method, and the administrative controls and quality assurance required to ensure compliance with applicable regulations and requirements. This PCP is not applicable to wastes transported to an off-site vendor for processing.

1.2 SCOPE This PCP applies to the processing of wet solid radioactive wastes generated as a result of plant operation and maintenance. This PCP does not apply to the treatment of mixed radioactive and hazardous wastes.

E2-5

WBN Process Control Program PCP Unit 0 Rev. 0002 Page 5of 14 2.0 DETAILS 2.1 WASTE CHARACTERISTICS A. Waste Streams

1. There are six waste streams that have been identified at WBN. These are primary resins, secondary resins, mobile demineralizer resin, filter elements, oil, and dry active waste.(DAW). This POP is not normally applicable to DAW. Other waste streams may be identified based upon plant operating characteristics.
2. Primary resins are collected in the spent resin storage tank forblending, decay, and storage. Primary resin sources are Chemical and ,Volume Control System (CVCS) letdown demineralizers, boron recovery demineralizers, and the fuel pool demineralizers.
3. Secondary resins are generated from the condensate polisher demineralizers.
4. Mobile demineralizer resins are fed by several sources including floor drain wastes, equipment drain wastes, laundry and hot shower wastes, and chemical wastes.
5. Filter elements will be accumulated from-one or more plant.;systems.

These are CVCS, seal injection, boron recovery, and spent fuel'pool clean-up.

6. Oil is contaminated with radioactivity from various areas within the plant, as a result of normal operation and maintenance.
7. The Condensate Demineralizer Waste Evaporator (CDWE) is not part of the Unit 1 license, but may be incorporated into the Unit 2 license application. If the CDWE is to be operated as part of the Unit 2 startup, the PCP shall be revised to incorporate the processing of the CDWE bottoms.
8. DAW is generated within the plant and is not appropriately attributed to the above mentioned waste streams. DAW normally includes paper, plastic, wood, metal, and other such material generated asa result of the operation and maintenance of the plant.

B. Waste Form Wastes are processed as appropriate to ensure that the minimum physical characteristics. required by 10 CFR 61 and disposal site criteria aremet. All class B and C waste must be stabilized. This shall be accomplished by placement into a high integrity container (HIC), or by solidification using a process that produces a product which meets the stability requirements of 10 CFR 61, per Section 2.2 of this PCP. The vendors topical report shall: include documentation of testing which verifies that the.HIC or solidified product meets these stability requirements. Additionally, WBN shall comply with Federal and/or State requirements imposed specifically on an approved HIC.or solidification product which limit the type and/or radioactive concentration of the waste to be placed in the HIC or solidified product.

C. Waste Classification Radioactive waste shall be classified as Class A, B, or C in accordance with the requirements of 10 CFR 61, using one or more of the classification methods given in the USNRC's "Low- Level Waste Licensing Branch Technical Position on Radioactive Waste Classification (May 1983)."and "NRC Branch Technical Position on Concentration Averaging and Encapsulation" dated January 17,1995 which replaced section C.3 of.the original 1983 Technical Position.

Waste classification shall be in accordance with approved station procedures.

The following specific requirements shall be incorporated in the program for sampling and analysis for waste classification:

1. Analysis frequency shall be determined by the waste classification and the date of the last sample taken. Class A waste shall be sampled at least every two years while class B and C waste shall be sampled at least annually for the nuclides listed in Table 1 andTable 2 of 1.0 CFR 61.55 unless the stream is unavailable for-sampling. For waste streams that are not processed annually, the annual analysis need not be performed until the waste is processed.
2. The results of analysis shall be used to develop isotopic.abundances and scaling factors for difficult to measure nuclides (i.e., beta.emitters and transuranics) based on correlations between those nuclides and more easily measured gamma emitters.

E2-7

WBN Process Control Program PCP Unit 0 Rev. 0002 Page 7 of14 2.1 WASTE CHARACTERISTICS (continued)

3. Calculational methods for determining the total activity in each container shall be developed which utilizes the results from the annual analysis.
4. The classification program shall establish criteria and include provisions for an increased frequency for sampling and analysis-required by paragraph 1 above, if the waste stream isotopic content may have :changed by a factor of 10.

2.2 PROCESSING OF WET RADIOACTIVE WASTE A. Processing Methods Wet radioactive waste processed at WBN shall be processed into a form acceptable for disposal at a licensed facility. Processing shall be performed utilizing vendor supplied equipment operated in accordance with the vendor's PCP and procedures. Any vendor selected to provide services or products used for compliance with 10 CFR 61 stability requirements shall have a topical report addressing 10 CFR 61 requirements under review or approved by the NRC. The topical reports and PCP's of other vendors may be referenced in this PCP even if all vendors are not actively providing service or products at WBN.

However, if any vendor is selected whose documents are not referenced, this document shall be revised to reference them.

B. System Qualification Tests

1. Prior to the initial solidification of a given waste stream using a specified process, a test shall be conducted to demonstrate the ability of the process to produce an acceptable waste form over the range of critical parameters identified during the prequalification testing. Bounds for critical parameters and specific operating limits shall be specified in the vendor's PCP.
2. These tests shall be performed on laboratory scale or full scale specimens and shall ensure that the acceptance criteria specified in Section 2.2.E are achieved.
3. The-dewatering process shall specify an endpoint for each dewatering evolution so as to assure that the acceptance criteria specified in Section 2.2.E are achieved.

E2-8

2.2 PROCESSING OF WET RADIOACTIVE WASTE (continued)

C. Batch Processing Each batch of waste offered for processing shall be sampled and analyzed, as appropriate, in accordance with site procedures, the vendor's PCP and the topical report that addresses the 10 CFR 61 stability requirements. This sampling shall:

1. Provide the necessary data to estimate curie content and to perform the waste classification analysis.
2. When solidification is involved, sampling shall provide data necessary to:
a. Ensure that waste stream parameters are within the bounds for. critical parameters established in the vendor's PCP and topical report.
b. Verify the application of preestablished mix ratios.

D. Testing/Inspections

1. Tests are performed on those wastes which are solidified to ensure the adequacy of the solidification agent and/or procedural technique. The vendor's PCP shall be used to verify the solidification of at least one representative test specimen from at least every tenth batch of each type waste being processed.
2. If any test specimen fails to verify solidification, the solidification of the batch under test shall be suspended until such time as additional test specimens can be obtained, alternative solidification parameters can be determined in accordance with the vendor's PCP, and a subsequent test verifies solidification. Solidification of the batch, may then be resumed using the alternative solidification parameters determined by the vendor's PCP.
3. If the initial test specimen from a batch fails to verify solidification, the vendor's PCP shall provide for the collection and testing of representative test specimens from each consecutive batch of waste-until'at least 3 consecutive test specimens demonstrate solidification.

E2-9

WBN Process Control Program PCP Unit 0 Rev. 0002 Page 9 of 14 2.2 PROCESSING OF WET RADIOACTIVE WASTE (continued)

E. Acceptance Criteria

1. All classes of waste shall satisfy the following acceptance criteria:
a. Liquid wastes shall be solidified.
b. Solid waste containing liquids shall not contain freestanding, liquid in excess of 1% of the internal volume of the container.
2. For wastes which require structural stability, the acceptance criteria are as follows:
a. The waste shall have structural stability.
b. Not withstanding the provisions of Section 2.2E.1, liquid wastesor wastes containing liquid shall be converted into a form in which the freestanding liquid shall not exceed 1% of the internal volume of the container when contained in a HIC, or 0.5% of the volume of the waste for waste processed to a stable form.

F. Corrective Actions With processing not meeting the above acceptance criteria or otherwise not meeting disposal site, shipping and/or transportation requirements, suspend shipment of inadequately processed waste and correct the PCP, procedures, and/or waste processing equipment as necessary to prevent recurrence. The disposition of inadequately processed wastes will be handledon a case-by-case basis.

WBN Process Control Program PCP Unit 0 Rev. 0002 Page 10 of 14 2.3 WASTE.STREAM PROCESSING METHODS A. Spent Resins

1. Normally spent resins are processed for disposal by dewatering. The resin is transferred to the liner or HIC where it is processed utilizing vendor supplied services, per Section 2.2.
2. Alternatively, resins may be processed for disposal by solidification. The resins shall be sampled for isotopic content and PCP parameters as defined in the vendor's PCP. The resins are transferred to the vendor's processing skid where they are solidified per Section 2.2.

B. Spent Filter Elements Spent filter elements are surveyed for dose rate prior to placement in a disposal container. The measured dose rate is used to calculate isotopic content using a dose-to-curie conversion and scaling factors per Section 2.1. Based on the isotopic content and waste classification, the appropriate process and container to be used for disposal are determined. Normally, filters are dewatered and placed in a liner or HIC; however, filters may be dried and handled, as DAW if conditions allow, or may be encapsulated.

C. Miscellaneous Wastes Sludges and other miscellaneous wastes will be collected and handled on a case-by-case basis, and processed per Section 2.2. Oil and, on a case-by-case basis, other acceptable liquid waste will normally be shipped off-site to a licensed incinerator for disposal.
