SUMMARY

During 2012 all solid, liquid, and gaseous radioactive effluents from the Kewaunee Power Station were well below regulatory limits. For individual effluent streams, the quarterly limit most closely approached was: GASEOUS: Ingestion Pathway-Organ TBody Quarterly Limit (mRems) 7.5 Actual Dose (mRems) 5.766E-04 (Id Quarter)% of Specification 7.688E-03 LIQUID: Ingestion Pathway-Organ Bone Quarterly Limit (mRems) 5.0 Actual Dose (mRems) 1.729E-02 (2nd Quarter)% of Limit 3.458E-01 SOLID: No upper limit for solid radioactive waste applies.Cubic Meters Shipped 4.68E+01 m 3 (1.65E+03 ft 3)

1.0 INTRODUCTION

This report is being submitted in accordance with the requirements of Kewaunee Technical Specifications, Section 5.6.2 and the Offsite Dose Calculation Manual, Section 15.2. It includes data from all effluent releases made from January 1 -December 31, 2012. The report contains summaries of the gaseous and liquid releases made to the environment including the quantity, characterization, time duration and calculated radiation dose at the site boundary resulting from these releases.

The report also includes a summation of solid radioactive waste disposal, revisions to the Process Control Program and the Offsite Dose Calculation Manual, and addresses the cumulative meteorological data.Values indicated as 0 (zero) in this report refer to actual values less than the detection limits. A table of these less than detectable (LLD) values is identified in sections 2.1 and 3.1.1. 1 Effluent Dose Limits Specifications are set to ensure that offsite doses are maintained as low as reasonably achievable while still allowing for practical and dependable operation of the Kewaunee Power Station.The Kewaunee Offsite Dose Calculation Manual (ODCM) describes the methodology and parameters used in: 1.) The calculation of radioactive liquid and gaseous effluent monitoring instrumentation alarm/trip set points.2.) The calculation of radioactive liquid and gaseous concentrations, dose rates and cumulative quarterly and annual doses. The ODCM methodology is acceptable for use in demonstrating compliance with 10 CFR 20.1301/1302; 10 CFR 50, Appendix I; and 40 CFR 190.Page 3 of 63

2.0 GASEOUS

EFFLUENTS 2.1 Lower Limits of Detection (LLD) for Gaseous Effluents Gaseous radioactive effluents are released in both the continuous mode and the batch mode.. The auxiliary building stack is sampled continuously for particulates, halogens and Strontium by an "off-line" sample train. This stack is also grab-sampled weekly for gaseous gamma emitters.

Batch releases are sampled prior to release for principal gaseous and particulate gamma emitters, halogens and tritium.The LLD's for gaseous radioanalyses, as listed in Table 13.2. 1-1 of the Kewaunee ODCM are: I I I I I LLD (ýtCi/ml)

11.0 INTRODUCTION

The Kewaunee OFFSITE DOSE CALCULATION MANUAL (ODCM) is established and maintained pursuant to Technical Specifications Section 5.5.1. The ODCM consists of two parts: Radiological Effluent Controls, Part I, and Calculational Methodologies, Part II.Part I, Radiological Effluent Controls, includes:

(1) The Radioactive Effluent Control Specifications (RECS) and Radiological Environmental Monitoring Programs (REMP) required by Technical Specification 5.5.1 and (2) descriptions of the information that should be included in the Annual Radiological Environmental Operating and Radioactive Effluent Release Reports I required by Technical Specifications 5.6.1 and 5.6.2 respectively.

Part II, Calculational Methodologies:

provides the methodology to manually calculate radiation dose rates and doses to individual persons in UNRESTRICTED AREAS due to the routine I release of gaseous and liquid effluents.

Long term cumulativeeffects are usually calculated through computer programs employing approved methodology, often using real-time meteorology in the case of gaseous effluents.

Other computer programs are utilized to routinely I estimate the doses due to radioactivity in liquid effluents'.

Manual dose calculations are performed when computerized calculations are not available.

The methodology stated in this manual is acceptable for use in demonstrating compliance with 1OCFR20.1302; 1OCFR50, Appendix I; and 40CFR190.More conservative calculational methods and/or conditions (e.g., location and/or exposure pathways) expected to yield higher computed doses than appropriate for the maximally exposed person may be assumed in the dose evaluations.

.3 The ODCM will be maintained

'at the station for use as a reference guide and training document of accepted methodologies and calculations.

Changes will be made to the ODCM calculational methodologies and parameters as is deemed necessary to assure reasonable conservatism in keeping with the principles of 10CFR50.36a and Appendix I for demonstrating radioactive effluents areALARA.11.1 Change Process I Instructions for defining the responsibilities and requirements for revision and control of both the ODCM and the RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL (REMM) are I located.in approved station procedure for Revision and Control of the REMM and ODCM.10 11.~0-1 1 KEWAUNEE POWER STATION OFFSITE DOSE CALCULATION MANUAL ODCM 13.0.1 Revision 14 April 18, 2012 13.0 USE AND APPLICATION 13.0.1 Definitions

The ODCM calculational methods specified in the DVR's 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 ODCM calculational methodology and parameters for calculating the doses due to the actual release rates of the subject materials are consistent with the methodology provided in Regulatory Guide 1.109, "Calculation of Annual Doses to man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977 and Regulatory Guide 1.111, "Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors," Revision 1, July 1977.These equations also provide for determining the actual doses based upon the historical average atmospheric conditions.

The release rate limitations for iodine-131, iodine-133, tritium, and radionuclides in particulate form with half-lives greater than 8 days are dependent upon the existing radionuclide pathways to man, in areas at and beyond the SITE BOUNDARY.

The pathways that were examined in the development of these calculations were: 1) individual inhalation of airborne radionuclides, 2) deposition of radionuclides onto green leafy vegetation with subsequent consumption by man, 3) deposition onto grassy areas where milk animals and meat producing animals graze with consumption of the milk and meat by man, and 4) deposition on the ground with subsequent exposure of man.13.2.3-4 KEWAUNEE POWER STATION OFFSITE DOSE CALCULATION MANUAL 13.2 RADIOACTIVE GASEOUS EFFLUENTS ODCM 13.2.4 Revision 14 April 18, 2012 13.2.4 GASEOUS RADWASTE TREATMENT SYSTEM DNC 13.2.4 The GASEOUS RADWASTE TREATMENT SYSTEM and the VENTILATION EXHAUST TREATMENT SYSTEM shall be used to reduce radioactive materials in gaseous waste prior to their discharge when the projected gaseous effluent air doses due to gaseous effluent releases to areas at and beyond the SITE BOUNDARY (Plant Drawing A-408) would be: a. > 0.2 mrad for gamma radiation; or b. > 0.4 mrad for beta radiation; or c. > 0.3 mrem to any organ in 31 day period.

which requires a program to ensure that the quantity of radioactivity contained in each gas storage tank and fed into the offgas treatment system is less than the amount that would result in a whole body exposure of > 0.5 rem to any individual in an UNRESTRICTED AREA, in the event of an uncontrolled release of the tanks contents.

Contents of the tank quantities shall be determined following the methodology in Branch Technical Position (BTP) ETSB 11-5,"Postulated Radioactive Release due to Waste-Gas System Leak or Failure." Radiological analysis for a waste gas decay tank rupture assumes the activity in a gas decay tank is taken to be the maximum amount that could accumulate from operation with cladding defects in 1 percent of the fuel elements.

This is at least ten times the expected number of defective fuel elements.

The maximum activity is obtained by assuming the noble gases, xenonand krypton, are accumulated with no release over a full core cycle. The gas decay tank inventory is calculated assuming nuclide decay, degassing of the reactor coolant with letdown at the maximum rate, and periodic purging to the gas decay tank. The maximum inventory for each nuclide during the degas and PURGE cycle is given in Appendix D, Table D.7-1. (reference 1)The resultant dose consequence for this accident is 0.1 rem whole body at the SITE BOUNDARY.

Summing the activities in USAR Table D.7-1 (reference

4) results in 42,792.74 curies. Using the noble gas dose conversion factors (DCF) contained in USAR Table D.8-1 (reference

5) referenced to Xe-133 results in a curie content of 52,000 curies when considered as Xe-133. Kewaunee Power Station does not have a calculation correcting the waste gas decay tank activity to a SITE BOUNDARY consequence of < 0.5 rem, therefore by limiting the activity in a waste gas decay tank to that which results in 0.1 rem at the SITE BOUNDARY, the 0.5 rem limit will not be exceeded.DVR 13.2.5 frequency is modified by a note that restricts performing the verification when additions are made to a tank to only when the reactor coolant system DOSE EQUIVALENT Iodine 131 (DEI-131) activity is greater than 1.0 pCi/gm (microcurie per gram). A calculation has shown that when a 1 % failed fuel assumption is used the resultant RCS DOSE EQUIVALENT XE-1 33 activity would be 595 [.Ci/gm (reference 2). Engineering experience is that with 1.0 pCi/gm DEI-131 RCS activity, the associated DEX-133 activity is approximately 200 pCi/gm. If with an assumption of 1% failed fuel calculations results are 595 pLCi/gm.DEX-1 33, and the dose consequences calculation also yields a 0.1 rem whole body at the SITE BOUNDARY by calculation then a gas decay tank on fill cannot exceed the activity limits of this requirement and the once per 31 day frequency is adequate.Reference 1.

The DNC requires the preparation and I submittal of a Special Report whenever'the calculated doses from plant generated radioactive effluents and direct radiation exceed 25 mrem to the total body or any organ, except the thyroid, which shall be limited to less than or equal to 75 mrem. It is highly unlikely that the resultant dose to a MEMBER OF THE PUBLIC will exceed the dose limits of 40 CFR Part 190 if the reactor remains within twice the dose design objectives of Appendix I, and if direct radiation doses from the reactor are kept small.The Special Report will describe a course of ACTION that should result in .the limitation of the annual dose to a MEMBER OF THE PUBLIC to within the 40 CFR Part 190 limits. For the purposes of the Special Report, it may be assumed that the dose commitment to the MEMBER OF THE PUBLIC from other uranium fuel cycle sources is negligible.

If the dose to any MEMBER OF.

To determine this minimum garden size, the following assumptions were made: (1) 20% of the garden was used for growing broad leaf vegetation (i.e., similar to lettuce and cabbage), and (2) a vegetation yield of 2 kg/M 2.I 13.5.2-I KEWAUNEE POWER STATION ODCM 13.5.3 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 13.5 RADIOLOGICAL ENVIRONMENTAL MONITORING 13.5.3 Interlaboratory Comparison Program This Kewaunee Interlaboratory Comparison Program is implemented by the RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL (REMM) and approved station procedures.

1.1 Radiation

Monitoring Instrumentation and Controls The liquid effluent monitoring instrumentation and controls installed at Kewaunee for controlling and monitoring normal radioactive material releases in accordance with 10 CFR 50, Appendix A, Criteria 60 and 64, are summarized as follows: 1) Alarm (and Automatic Termination)

-R-18 provides this function on the liquid radwaste effluent line, R-19 on the Steam Generator blowdown.2) Alarm (only) -R-20 and R-16 provide alarm functions for the Service Water discharges.

3) Composite Samples -Samples are collected weekly from the steam generator blowdown and analyzed by gamma spectroscopy.

Samples are collected weekly from the Turbine Building Sump and analyzed by gamma spectroscopy.

The weekly samples are composited for monthly tritium and gross alpha analyses and for quarterly Sr-89, Sr-90, and Fe-55 analyses.

During periods of identified primary-to-secondary leakage (with the -secondary activity > 1.OE-05 pCi/ml), grab samples from the Turbine Building sump are collecied daily and analyzed by gamma spectroscopy.

These samples are composited for monthly tritium and gross alpha analyses and for quarterly Sr-89, Sr-90, and Fe-55 analyses.4) Liquid Tank Controls -All radioactive liquid tanks are located inside the Auxiliary Building and contain the suitable confinement systems and drains to prevent direct, unmonitored release to the environment.

A liquid radioactive waste flow diagram with the applicable, associated radiation monitoring instrumentation and controls is presented as Figure 1.1.2 Liquid Effluent Monitor Setpoint Determination Per the requirements of Technical Specification 5.5.3.b and ODCM Normal Condition 13.3.1, alarm setpoints shall be established for the liquid effluent monitoring instrumentation to ensure that the release concentration limits of ODCM Normal Condition 13.1.1 are met (i.e., the concentration of radioactive material released in liquid effluents to UNRESTRICTED AREA shall be limited to ten times the concentrations specified in 10 CFR 20, Appendix B, Table 2, Column 2, for radionuclides and 2.OE-04 pCi/mI for dissolved or entrained noble gases). The following equation 1 must be satisified to meet the liquid effluent restrictions:

c: 1x C(F +f)c< (1.1)f Adapted from NUREG-0133 to include the application of 10 times the Effluent Concentration (EC) of 10 CFR 20, Appendix B, Table 2, Column 2.1.0-1 K\ EWAU1NEE POWER STATI IUN ODCM 1.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 where: 10xC = ten times the effluent concentration limit of 10 CFR 20, Appendix B, Table 2, Column 2, in pCi/.l. For dissolved and entrained noble gases equals 2x 10-4 pCi/ml.C = the setpoint, in pCi/ml, of the radioactivity monitor measuring the radioactivity concentration in the effluent line prior to dilution and subsequent release; the setpoint, which is inversely proportional to the volumetric flow of the effluent line and proportional to the volumetric flow of the dilution stream plus the effluent stream, represents a value which, .if exceeded, would result in concentrations exceeding the limits of ODCM Normal Condition 13.1.1.f = the flow rate at the radiation monitor location in volume per unit time, but in the same units as F, below.F = the dilution water flow rate as measured prior to the release point, in volume per unit time.[Note that if nodilution.

is provided, c < C. Also, note that when (F) is large compared to (f), then (F + f) F.]1.2.1 Liquid Effluent Monitors (Radwaste, Steam Generator Blowdown and Service Water)The setpoints for the liquid effluent monitors at the Kewaunee Power Station are determined by the following equations:

~CW >SEN. )SP< X i + bkg (1.2)10 x BC* -ECi where: SP alarm setpoint corresponding to the maximum allowable release rate (cpm)Ci = the concentration of radionuclide "i" in the liquid effluent (pCi), to include gamma emitters only 10xECi = ten times the EC value corresponding to radionuclide "i" from 10 CFR 20, Appendix B, Table 2, Column 2 (pCi/ml)1.0-2 KEWAUNEE POWER STATION ODCM 1.0 OFFSITE DOSE CALCULATION MANUAL Revision.14 April 18, 2012 SENi = the sensitivity value to which the monitor is calibrated for radionuclide "i" (cpm per pCi/ml). The default calibration value from Table 1..1 may be used for gamma emitting radionuclides in lieu of nuclide specific values.CW the circulating water flow rate (dilution water flow) at the time of release (gal/min)RR = the liquid effluent release rate (gal/min)bkg the background of the monitor (cpm)The radioactivity monitor setpoint equation (1.2) remains valid during outages when the circulating water dilution is at its lowest. Reduction of the waste stream flow.(RR) may be necessary during these periods to meet the discharge criteria.At its lowest value, CW will equal RR and equation (1.2) reverts to the following equation: ,__,(C i x SENi)SP < Z + bkg (1.3)(1 Ci)1.2.2 Conservative Default Values Non-gamma emitting radionuclides (H-3, Fe-55, Sr-89/90) are not detected by the effluent monitor and, therefore, are not directly included in the above setpoint equation.

These non-gamma radionuclides can, however, contribute a sizable fraction of the total EC. limit (refer to. Appendix..C).

The method specified below for establishing default setpoints provides conservatism to account for these non-gamma emitters and ensures that.the.setpoint meets the requirements of ODCM Normal Condition 13.3.1 including all radionuclides.

Refer to Appendix C for further discussion.

Conservative alarm setpoints have been determined through the use of generic, default parameters.

Table 1.1 summarizes all current default values in use for Kewaunee.

They are based upon the following:

a) substitution of the default effective EC (ECe) value of 1.OE-06 pCi/ml (refer to Appendix C for justification), where: EC,- 1 (1.4)(EC 1)1.0-3 KEVVAUNEE POWER STATION ODCM 1.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 I April 18, 2012 b) substitution of the lowest operational circulating water flow, in gal/min; and, 3 C) uibhstitutinn of the highest effluent release , in gal/mi, d) substitution of the default monitor sensitivity.

I The default setpoint equation is provided below: I sP<E C RxlxENxCWR+bkg (1.5)1.3 Liquid Effluent Concentration Limits -10 CFR 20 ODCM Normal Condition 13.1.1 limits the concentration.of radioactive material in liquid effluents (after dilution in the Circulating Water System) to less than ten times the concentrations as specified in 10 CFR 20, Appendix B, Table 2, Column 2 for radionuclides other than noble gases. Noble gases are limited to a diluted concentration of 2E-04 pCi/ml. Release rates are controlled and radiation monitor alarm setpoints are established to ensure that these concentration limits are not exceeded.

In the event any liquid release results in an alarm setpoint being exceeded, an evaluation of compliance with the concentration limits of ODCM Normal Condition 13.1.1 may be performed using the following equation: where: E[(C +(10 x EC,)) x (RR CW)] 1 (1.6)Ci = concentration of radionuclide "i" in the undiluted liquid effluent (PCi/ml)l0xECi -= ten times the EC value corresponding to radionuclide "i" from a 10 CFR 20, Appendix B, Table 2, Column 2 (pCi/ml)= , 2E-04 pCi/ml for dissolved or entrained noble gases RR = the liquid effluent release rate (gal/min)CW the circulating water flow rate (dilution water flow) at the time of the release (gal/min)'!I 1.0-4 KEWAUNEE POWER STATION ODCM 1.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 1.4 Liquid Effluent Dose Calculation

The radionuclides included,.in the periodic dose assessment per the requirements of ODCM Normal Condition 13.1.2 and Verification Requirement 13.1.2.1 are those as identified by gamma spectral analysis of the liquid waste samples collected and analyzed per Verification Requirement 13.1.1.1, Table 13.1.1-1.Radionuclides requiring radiochemical analysis (e.g.,.Sr-89 and Sr-90) will be added to the dose analysis at a frequency consistent with the required minimum analysis frequency of Table 13.1.1-1.In lieu of the individual radionuclide dose assessment as presented above, the following simplified dose calculational equation may be used for demonstrating compliance with the dose limits of ODCM Normal Condition 13.1.2.

These waste streams are normally separated from the radioactive streams. However, due mainly to infrequent, minor system leaks, and anticipated operation occurrences, the potential exists for these systems to become slightly contaminated.

At Kewaunee, the secondary system demineralizer resins, the service water pretreatment system sludges, the make-up water system resins, and the sewage treatment plant sludges are waste streams that have the potential to become contaminated at very low levels. During the yearly testing of a batch of pre-treatment sludge, it was found approximately 15,000 cubic feet of sludge had been contaminated with Cs-137 and Co-60.The potential radiation doses to MEMBERS OF THE PUBLIC from these onsite disposal methods are well below 1 mrem per year. This dose is in keeping with the guidelines of the National Council on Radiation Protection (NCRP) in their Report No. 91, in which the NCRP established a "negligible individual risk level" at a dose rate of 1 mrem per year.It is for these type wastes that the NRC acknowledged in Information Notice No. 83-05 and 88-22 that the levels of radioactive material are so low that control and disposal as a radwaste are not warranted.

The potential risks to man are negligible and the disposal costs as a radwaste are unwarranted and costly.1.0-8 KEWAUNEE POWER STATION ODCM 1.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 This waste material will be monitored and evaluated prior to disposal to ensure its radioactive material content is negligible.

It shall then be disposed of in a normal conventional manner with records being maintained of all materials disposed of using these methods.Approvals for specific alternate disposal methods are listed in Appendix D. Currently, only service water pretreatment (SWPT) facility lagoon sludge and sewage treatment plant sludge have been approved for disposal by land spreading.

1.7 Heating

Boiler Blowdown Operation with Primary-to-Secondary Leak During operation with a primary-to-secondary leak, the potential exists for non-radioactive systems to become contaminated.

One such system is the heating system.Activity is transferred from the reactor coolant system into the secondary main steam system through the leak and then into the heating system. Heating boiler operation following operation with a primary-to-secondary leak will result in the heating boiler becoming contaminated.

When the heating boiler is operated, it must be periodically blown down to remove impurities, which collect in. the system. This blowdown is normally directed to the steam generator blowdown tank but can be diverted to the circulating water discharge.

Either way, the blowdown becomes a release. path. for radioactivity to the environment.

The heating boiler blowdown is sampled, using current plant procedures, whenever the primary-to-secondary leakage exceeds 10 gallons per day and the gross gamma activity exceeds 1.OE-06 pCi/ml or tritium activity exceeds 1.OE-05 pCi/ml. The results of these samples allow for the activity being released to the environment to be quantified.

This is similar to the method used for the turbine building sump release path.. The radioactive effluent limits of 10 CFR Part 20, 40 CFR 190, and Technical Specifications can therefore be maintained..

2.1 Radiation

Monitoring Instrumentation and Controls The gaseous effluent monitoring instrumentation and controls at Kewaunee for controlling and monitoring normal radioactive material releases in accordance with 10 CFR 50, Appendix A, Criteria 60 and 64, are summarized as follows: 2.1.1 Waste Gas Holdup System The vent header gases are collected by the waste gas holdup system. Gases may be recycled to provide cover gas for the CVCS hold-up tanks or held in the waste gas tanks for decay prior to release. Waste gas decay tanks are batch released after sampling and analysis.

The tanks are discharged via the Auxiliary Building vent. R-13 and/or R-14 provide noble gas monitoring and automatic isolation.

2.1.2 Condenser

Evacuation System The air ejector discharge is monitored by R-1 5. Releases from this system are normally via the Auxiliary Building vent and are monitored by R-13 and/or R-14.2.1.3 Containment Purge Containment purge and ventilation is via the containment stack for the 36-inch RBV system but via the auxiliary building stack for the 2-inch vent and mini-purge blower system. The stack radiation monitoring system consists of: " a noble gas activity monitor providing alarm and automatic termination of release (R-12 and R-21),* an iodine sampler, and* a particulate sampler.Effluent flow rates are determined empirically as a function of fan operation (fan curves).Sampler flow rates are determined by flow rate instrumentation.

2.1.4 Auxiliary

Building Vent The Auxiliary Building vent receives discharges from the waste gas holdup system, condenser evacuation system, fuel storage area ventilation, Auxiliary Building radwaste processing area ventilation, 2-inch containment pressure relief purge/vent system, and AuxiliaryBuilding general area. All effluents pass through the R-13 and/or R-14 channels which contain:* a noble gas monitor* an iodine sampler, and* a particulate sampler.2.0- 1 KEWAUNEE POWER STATION ODCM 2.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 The noble gas monitor provides auto isolation of any waste gas decay tank release and diverts other releases through the special ventilation system. Effluent flow rates are determined by installed flow measurement equipment or as a function of fan operation (fan curves). Sampler flow rates are determined by flow rate instrumentation.

2.1.5 Containment

Mini-PurgeNent System Slight pressure buildup in containment is a recurring event resulting from normal operation of the plant. Prior to exceeding 2 psig in containment, this excess pressure is vented off. Air from containment is routed to the Auxiliary Building ventilation system, via the post-LOCA hydrogen recombiner piping and then out through the Auxiliary Building vent stack. The system is also designed to allow a continuous supply of fresh air to be introduced into containment via a mini-blower to purge gases. An alarm of the Auxiliary Building vent stack monitor (R-13 or R-14) or the containment building airborne radioactivity monitors (R-11, R-12) provides automatic isolation.

2.1.6 Steam

Generator PORV Release With Primary-to-Secondary Leakage IF the plant is operating with Steam Generator leakage from the primary side to the secondary, THEN release of steam through the Steam Generator PORVs will constitute a radiological release. There are no monitors on this release path, so accurate data collection is important.

The appropriate procedures provide directions for release permit preparations.

2.1.7 Non-routine Discharge Locations Periodically, non-routine breaches are made in the Auxiliary and Containment buildings that might allow the release of the atmosphere, which contains some levels of radioactivity.

These breaches include, but are not limited to, opening the Containment equipment hatch during outages, holes cut in walls or ceilings to allow for moving equipment in or out of the Radiologically Controlled Areas (RCAs). All efforts to maintain these areas at negative pressure will be made. IF negative pressure cannot be maintained (i.e., more exhaust than supply fan volume), THEN supply ventilation to the area must be secured. Criteria for determining if and when a release occurs from these areas is provided in implementing procedures.

As possible, the effects of these possible releases shall be evaluated beforehand.

Any actual releases shall be documented and included in the monthly, quarterly and annual reports as appropriate.

2.1.8 Miscellaneous

Releases -IF the plant is experiencing primary-to-secondary leaks in the steam generators, THEN the secondary steam side will become contaminated.

Any release of steam will constitute -an effluent,, gaseous release, which will need to be accounted for in the effluent release program.Historically, if this condition had existed, the affects were considered to be minimal, and therefore were NOT included in the ODCM. The potential sources are too numerous to specifically'call out here. However, in the event conditions arise that such releases occur, the methods outlined in the ODCM for dose calculation of the releases will be applied, and the results included in the annual effluent release report.A gaseous radioactive waste flow diagram with the applicable, associated radiation monitoring instrumentation and controls is presented as Figure 2.2.0-2 KEWAUNEE POWER STATION ODCM 2.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 2.2 Gaseous Effluent Monitor Setpoint Determination

2.2.1 Containment

and Auxiliary Building Vent Monitor Per the requirements of ODCM Normal Condition 13.3.2, alarm setpoints shall be established for the gaseous effluent monitoring instrumentation to ensure that the release rate of noble gases does not exceed corresponding dose rate at the SITE BOUNDARY of 500 mrem/year to the total body or 3000 mrem/year to the skin. Based on a grab sample analysis of the applicable release (i.e., grab sample of the Containment vent or Auxiliary Building vent), the radiation monitoring alarm setpoints may be established by the following calculational method: FRACrb.= [4.72E + 02X x/Qx VFx ,(Ci.xKi)]

500 (2.1)FRACski. = [4.72E + 02 x x/Q x VF x (_(Ci x (Li + 1.1 Mi))]+ 3000 (2.2)where: FRACtb = fraction of the allowable release rate for the total, body based on the identified radionuclide concentrations and the release flow rate FRACski. = fraction of the allowable release rate for skin based on the identified radionuclide concentrations and the release flow rate X/Q annual average meteorological dispersion for direct exposure to noble gas at the.controlling SITE BOUNDARY location (sec/m 3 , from Table 2.3)VF ventilation system flow rate for the applicable release point and monitor (ft 3/min, from Table 2.2)C, ,= .concentration of noble gas. radionuclide "i" as determined by radioanalysis of grab sample ([LCi/cm 3) -Ki .total body dose conversion, -factor for noble gas radionuclide

SP = [I (Ci x SEN) + FRAC]+ bkg (2.3)where: SP SENi bkg.. = alarm setpoint corresponding to the maximum allowable release rate (cpm)= the sensitivity value to which the monitor is calibrated for radionuclide

'T" (cpm per iCi/cm 3), use the default value from Table 2.2 if radionuclide specific sensitivities are not available background of the monitor (cpm)2.2.2 Conservative Default Values A conservative alarm setpoint can. be established, in lieu of the individual radionuclide evaluation based on the grab sample analysis, to eliminate the potential of periodically having to adjust the setpoint to reflect minor changes in radionuclide distribution and variations in release flow rate. The alarm setpoint may be conservatively determined by the default values presented in Table 2.2. These values are based upon: a) substitution of the maximum ventilation flow rate, I I I i I I I U I I I I I I I b) substitution of a radionuclide distribution 1 comprised of 95% Xe-133, 2% Xe-135, 1%Xe-133m, 1% Kr-88 and 1% Kr-85; and, c) application of an administrative multiplier

' of 0.5 to conservatively assure that any simultaneous releases do not exceed the maximum allowable release rate.For this radionuclide distribution, the alarm setpoint based on the total body dose rate is more restrictive than the corresponding setpoint based on the skin dose rate. The resulting conservative, default setpoints are presented in Table.2.2.

'Adopted from ANSI N237-1976/ANS-18.1, Source Term Specifications, Table 6.2.0 -4 I KEWAUNEE POWER STATION ODCM 2.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 2.3 Gaseous Effluent Instantaneous Dose Rate Calculations

-10 CFR 20 2.3.1 SITE BOUNDARY Dose Rate -Noble Gases.ODCM Normal Condition 13.2.1.a limits the dose rate at the SITE BOUNDARY due to noble gas releases to < 500 mrem/yr to the total body, and < 3000 mrem/yr to the skin. Radiation monitor alarm setpoints are established to ensure that these release limits are not exceeded.

In the event any gaseous releases from the station results in the alarm setpoints being exceeded, an evaluation of the UNRESTRICTED AREA dose rate resulting from the release may be performed using the following equations:

Dtb=x/QxY KixQi (2.4)and(Li,+ 1.1Mi)XQ " (2.5)where: D ib = total body dose rate (mrem/yr)D s skin dose rate (mrem/yr)x/Q atmospheric dispersion for direct exposure to noble gas at the controlling SITE BOUNDARY (sec/m 3 , from Table 2.3)Q1 average release rate of radionuclide "i" over the release period under evaluation (p.Ci/sec)

To demonstrate compliance with this limit, an evaluation is performed at a frequency no greater than that corresponding to U the sampling and analysis time period for continuous releases (e.g., nominally once per 7 days)and for batch releases on the time period over which any batch release is to occur. The following equation may be used for the dose rate evaluation:

Do =X/Qxl RxQij (2.6) 1 where: 3 Do = average organ dose rate over the sampling time period (mrem/yr)X/Q= atmospheric dispersion to the controlling SITE BOUNDARY for the inhalation pathway (sec/rin 3 , from Table 2.3) 1 R= dose parameter for radionuclide "i", (mrem/yr per _LCi/m 3) for the child inhalation pathway from Table 2.6 1 Q. average release rate over the appropriate sampling period and analysis frequency for radionuclide "i", k-131, 1-133, tritium or other radionuclide in .3 particulate form with half-life greater than 8 days (jiCi/sec)

By substituting 1500 mrem/yr for Do solving forQi, an allowable release rate for 1-131 can be determined.

Based on the annual average meteorological dispersion (see Table 2.3) and the most limiting potential pathway, age group and. organ .(inhalation pathway, child thyroid -.Ri = 1.62E+07 mrem/yr per ipCi/m 3) the allowable release ra.te .for 1-131 is 6.43 pCi/sec. An I added conservatism factor of 0.25 has been included, in this calculation to account for any potential dose contribution from other radioactive particulate material.

For a 7-day period, which is the nominal sampling and analysis frequency for 1-131, the cumulative allowable release is I 3.9 Ci. Therefore, as long as the 1-131 releases in any 7-day period do not exceed 3.9 Ci, no additional analyses are needed to verify compliance with the ODCM Normal Condition 13.2.1.b limits on allowable release rate. 5 I 2.0-61 KEWAUNEE POWER STATION ODCM 2.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 2.4 Gaseous Effluent Dose Calculations

-10 CFR 50 2.4.1 UNRESTRICTED AREA Dose -Noble Gases ODCM Normal Condition 13.2.2 requires a periodic assessment of releases of noble gases to evaluate compliance with the quarterly dose limits of (< 5 mrad, gamma-air and _< 10 mrad, beta-air) and the calendar year limits (<10 mrad, gamma-air and < 20 mrad, beta-air).

It is recognized that for some particulate radionuclides (e.g., Co-60 and Cs-137), the ground plane exposure pathway may represent a higher dose contribution than either the vegetation or grass-cow-milk pathway. However, use of the 1-131 thyroid dose parameter for all radionuclides will maximize the organ dose calculation, especially considering that no other radionuclide-has a higher dose parameter for any organ via any pathway than 1-131 for the thyroid via the grass-cow-milk pathway.The location of exposure pathways and the maximum organ dose calculation may be based on the available pathways in the surrounding environment of Kewaunee as identified by the annual land-use census. Otherwise, the dose will be evaluated based on the predetermined controlling pathways as identified in Table 2.3. .2.0-9 KEWAUNEE POWER STATION ODCM 2.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 2.5 Gaseous Effluent Dose Projection ODCM Normal Condition 13.2.4 requires that the VENTILATION EXHAUST TREATMENT SYSTEM be used to reduce radioactive material levels prior to discharge when projected doses exceed one-half the annual design objective rate in any 31 days, i.e., exceeding:

Any exposure attributable to on-site sources will be evaluated based on the results of the environmental monitoring program (TLD measurements) or by calculational methods. NUREG-0543 describes acceptable methods for demonstrating compliance with 40 CFR Part 190 when radioactive effluents exceed the Appendix I portion of the specifications.

2.7 Incineration

of Radioactively Contaminated Oil During plant operation, radioactively contaminated oils are generated from various pieces of equipment operating in the plant. The largest source of contaminated oil is the reactor coolant pump lubricating oil, which is periodically changed for preventive maintenance reasons. 10 CFR Part 20 allows licensees to incinerate radioactively contaminated oils on site provided that the total radioactive effluents from the facility conform to the requirements of 10 CFR Part 50, Appendix I.Radioactively contaminated oil, which is designated for incineration, will be collected in containers, which are uniquely serialized such that the contents can be identified and tracked. Each container will be sampled and analyzed for radioactivity.

The. isotopic concentrations will be recorded for each container.

The heating boiler will be utilized to incinerate the radioactively contaminated oil collected on site. A gaseous radwaste effluent dose calculation, as prescribed in Section 2.3 of the ODCM, will be performed to insure' that the limits established by ODCM Normal Condition 13.2.1, 13.2.2 and 13.2.3 are not exceeded.

Release of the activity is assumed to occur at the time the contaminated oil is transferred into the heating boiler fuel oil storage tank and will be accounted for using established plant procedures.

This will be valid for an assumedrelease from the fuel oil storage tank vent, fill piping, or from the boiler exhaust stack. See Figure 3 for a description of the heating boiler fuel oil system.2.8 Total Dose The purpose of this section is to describe the method used to calculate the cumulative dose contributions from liquid and gaseous effluents in accordance with KPS Technical Specifications for total dose.. This method can also be used to demonstrate compliance with the Environmental Protection Agency (EPA) 40CFR1 90, "Environmental Standards for the Uranium Fuel Cycle".Compliance with the KPS Technical Specification dose objectives for the maximum individual demonstrates compliance with the EPA limits to any MEMBER OF THE PUBLIC, since the design dose objectives from 10CFR50, Appendix I are much lower than-the 40CFR190 dose limits to the general public. With the calculated doses from the releases of radioactive materials in liquid or gaseous effluents exceeding twice the limits outlined in ODCM DNC 13.1.2, 13.2.2, and 13.2.3, a special analysis shall be performed.

The purpose of this analysis is to demonstrate if the total dose to any MEMBER OF THE PUBLIC (real individual), from all uranium fuel cycle sources (including direct radiation contributions from the reactor unit, from outside storage areas and from all real pathways) is limited to less than or equal to 25 mrem per year to the total body or any organ, except the thyroid, which is limited to 75 mrem per year.2.0-11 I I/Z-A/Av M I'IIr I-O r\EVV/INrF POWEIR STATION ODCM 2.0 OFFSITE DOSE CALCULATION MANUAL Revision 14 I April 18, 2012 If required, the total dose to a MEMBER OF THE PUBLIC will be calculated for all significant effluent release points for all real pathways including direct radiation.

Effluent releases from Point Beach U Nuclear Plant must also be considered due to its proximity.

Calculations will be based on the equations in Sections 1.4, 2.4.1, and 2.4.2, with the exception that usage factors and other site specific parameters may be modified using more realistic assumptions, where appropriate.

The direct radiation component from the facility can be determined using environmental TLD results.These results will be corrected for natural background and for actual occupancy time of any areas I accessible to the general public at the location of maximum direct radiation.

It is recognized that by including the results from the environmental TLDs into the sum of total dose component, the direct radiation dose may be overestimated.

The TLD measurements may include the exposure from noble gases, ground plane deposition, and shoreline deposition, which have already been included in the i summation of the significant dose pathways to the general public. However, this conservative method can be used, if required, as well as any other method for estimating the direct radiation dose from i contained radioactive sources within the facility.

The methodology used to incorporate the direct 3 radiation component into total dose estimates will be outlined whenever total doses are reported.Therefore, the total dose will be determined based on the most realistic site specific data and parameters to assess the real dose to any MEMBER OF THE PUBLIC.1 2 -I-I 2.O- 1

Technical Basis for Effective Dose Factors -Liquid Effluent Releases To verify that the current approach to determining environmental doses using a simplified method has remained consistent since the previous analysis (performed using effluent data from 1981-1983), a similar evaluation was performed using the liquid effluent release data from 2000-2002.

From the effluent data, the dose contribution of the radionuclide mixture can be obtained to provide a simplified method of determining compliance with the dose limits of ODCM Normal Condition 13.1.2. For the radionuclide distribution of effluents from the Kewaunee Power Station, the controlling organ is either the GI-LLI or the liver. The calculated GI-LL1 dose is almost exclusively dictated by the Nb-95 releases; the liver dose is mostly a function of the Cs-134 and Fe-55 releases.

The radionuclides, Fe-55, Co-58, Co-60, Sr-90, and Cs-137 contribute essentially all of the calculated total body dose. The results of this evaluation are presented in Table A-I. The individual nuclide doses used in the dose comparisons of Table A-I were calculated using the total curies released via batch and continuous releases as reported in the Annual Radioactive Effluent Release Report, weighted by the appropriate dose factors.Tritium is not included in the limited analysis dose assessment for liquid releases, because the potential dose resulting from normal reactor releases is negligible.

From 2000-2002, the maximum tritium release from the Kewaunee Power Station to Lake Michigan was 270 curies.The calculated total body dose from such a release is 1.36E-02 mrem/yr via the fish ingestion and drinking water pathways.

This amounts to 0.07% of the design objective dose of 3 mrerm/yr.Furthermore, the release of tritium is a function of operating time and power level and is essentially unrelated to radwaste system operation.

For purposes of simplifying the details of the dose calculational process, it is conservative to identify a controlling, dose significant radionuclide and limit the calculational process to the use of the dose conversion factor for this nuclide. Multiplication of the total release (i.e., cumulative activity for all radionuclides) by this dose conversion factor provides for a dose calculational method that is simplified while also being conservative.

While not present in the 2000-2002 liquid effluent releases, it still remains conservative to use the Cs-134 dose conversion factor (7.09E+05 mrem/hr per !aCi/ml, liver) to evaluate the maximum organ dose. Only the reactor-generated radionuclide Nb-95 has a higher dose conversion factor (1.5]E+06 mrem/hr per jiCi/ml, GI-LL1). However, since Nb-95 releases are typically less than 5% of the total releases, it is conservative to use the Cs-134 factor. By this approach, the maximum organ dose will be routinely overestimated.

For 2000, using this simplified conservative method (CW value of 2.OOE+05 gpm) would overestimate the maximum organ dose as reported in the Annual Radioactive Effluent Release Report by a factor of 234; for 2001, the conservatism is a factor of 109; and for 2002, a factor of 730. This comparison is shown in Table A-2.A-2 KEWAUNEE POWER STATION ODCM App-A OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 For the total body calculation, the Cs-134 dose factor (5.79E+05 mrem/hr per iLtCi/ml, total body)is again used since it is higher than the identified dominant nuclides.

For 2000, using this simplified conservative dose calculational method would overestimate the total body dose by a factor of 253; for 2001, the conservatism is a factor of 105; and for 2002, a factor of 601.For evaluating compliance with the dose limits of ODCM Normal Condition 13.1.2 the following simplified equations may be used: Total Body Dtb =1.67E- 02 x VOL Db= x Acs-134.

These effective factors, which can be based on typical radionuclide distributions of releases, can be applied to the total radioactivity released to approximate the dose in the environment (i.e., instead of having to perform individual radionuclide dose analyses only a single multiplication (Ke~f, Meff or Neff) times the total quantity of radioactive material released would be needed). This approach provides a reasonable estimate of the actual dose while eliminating the need for a detailed calculational technique.

Determination of Effective Dose Factors Effective dose transfer factors are calculated by the following equations:

Keff= I(K<ix fi)(B.1)where: Ken-Ki fii= the effective total body dose factor due to gamma emissions from all noble gases released-the total body dose factor due to gamma emissions from each noble gas radionuclide "i" released-the fractional abundance of noble gas radionuclide "i" relative to the total noble gas activity (L + I. IM)e, = I[(Li + 1.1 Nt)x f](B.2)where: (L + 1.1 M)er = the effective skin dose factor due to beta and gamma emissions from all noble gases released (Li + 1.1 Mi) = the skin dose factor due to beta and gamma emissions from each noble gas radionuclide "i" released Merff Z(M x f')(B.3)B-2 I KEWAUNEE POWER STATION ODCM App-B I OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 3 where: Merf = the effective air dose factor due to gamma emissions from all noble gases released I Mi the air dose factor due to gamma emissions from each noble gas radionuclide "i" released Nfr= Z(Nix fi) (B.4)where:U Neoc = the effective air dose factor due to beta emissions from all noble gases released 3 Ni the air dose factor due to beta emissions from each noble gas radionuclide "i" released 3 Normally, it would be expected that past radioactive effluent data would be used for the determination of the effective dose factors. However, the noble gas releases from Kewaunee I have been maintained to such negligible quantities that the inherent variability in the data makes any meaningful evaluations difficult.

For the years of 2000, 2001 and 2002, the total noble gas releases have been limited to 2.54E-04 Ci for 2000, 1.37E-01 Ci for 2001, and 1.91E-02 Ci for 2002. Therefore, in order to provide a reasonable basis for the derivation of the effective noble I gas dose factors, the primary coolant source term from ANSI N237-1976/ANS-18.1, "Source Term Specifications," has been used as representing a typical distribution.

The effective dose factors as derived are presented in Table B-1.Application 3 To provide an additional degree of conservatism, a factor of 0.50 is introduced into the dose calculational process when the effective dose transfer factor is used. This conservatism provides additional assurance that the evaluation of doses by the use of a single effective factor will not I significantly underestimate any actual doses in the environment.

For evaluating compliance with the dose limits of ODCM Normal Condition 13.2.2, the following simplified equations may be used: Dy 3.7 E 8 x X/Qx Mffx iQ, (B.5)0.50 D= 7 E 0 8 x X/Q x Nf- x ZQi (B.6)0.50 where: B-3 KEWAUNEE POWER STATION OFFSITE DOSE CALCULATION MANUAL ODCM App-B Revision 14 April 18, 2012 Dy= air dose due to gamma emissions for the cumulative release of all noble gases (mrad)= air dose due to beta emissions for the cumulative release of all noble gases (mrad)= atmospheric dispersion to the controlling SITE BOUNDARY (sec/mi 3)z/Q Merr Neff Y XQ= 5.3E+02, effective gamma-air dose factor (mrad/yr per VtCi/rn)= 1.1E+03, effective beta-air dose factor (mrad/yr per ViCi/m 3)= cumulative release for all noble ga' radionuclides

The determination of allowable radionuclide concentration and corresponding alarm setpoint is a function of the individual radionuclide I distribution and corresponding EC values.In order to limit the need for routinely having to reestablish the alarm setpoints as a function of .changing radionuclide distributions, a default alarm setpoint can be established.

This default setpoint can be conservatively based on an evaluation of the radionuclide distribution of the liquid effluents from Kewaunee and the ECe value for this distribution.

3 The effective EC value for a radionuclide distribution can be calculated by the equation: ECe = -(C. 1)where: 3 ECe = an effective EC value for a mixture of radionuclide

(ýtCi/ml)C= concentration of radionuclide "i" in the mixture 3 ECI the 10 CFR 20, Appendix B, Table 2, Column 2 EC value for radionuclide I"'(Y.tCi/mI)

I Based on the above equation and the radionuclide distribution in the effluents for past years from Kewaunee, an ECe value can be determined.

Effluent release data from 2000-2002 was used to 1 generate the results presented in Table C-I. The most limiting effective EC (for gamma emitting radionuclides) was for the calendar year 2001, with a calculated value of 5.98E-06 [iCi/ml. For conservatism in establishing the alarm setpoints, a default effective EC value of 1.OE-06 jtCi/ml I was selected.

The overall conservatism of this value is reaffirmed for future releases considering that I.OE-06 ýtCi/ml is as or more restrictive than the individual EC values for the principal fission and activation products of Co-58, Co-60 and Cs-137. Overall, use of this effective EC I C-2 KEWAUNEE POWER STATION ODCM App-C OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 value provides a factor of six (6) conservatism based on the 2000-2002 radionuclide distribution for gamma emitters.Being a non-gamma emitter, tritium is not detected by the effluent monitor. While tritium accounts for nearly all of the activity, it is not a significant contributor when determining the alarm setpoint for release rate evaluations.

Examining releases over the years 2000-2002, the average, diluted H-3 contribution to its limiting concentration (i.e., fraction of concentration limit -10 x EC) in liquid effluents was 0.004%. This contribution is not expected to change significantly over time, since the concentration of H-3 in effluents can be expected to remain fairly consistent in effluent releases regardless of fuel conditions, activation product releases, and waste processing.

Based on relative abundances, other non-gamma emitting radionuclides (Fe-55 and Sr-89/90)contributed up to 30% of the concentration limit (30% for CY 2001). It is reasonable to assume that the abundances of these non-gammas will remain the same relative to other fission and/or activation products under varying conditions.

Therefore, uinder conditions of elevated effluent radionuclide levels, the gamma-emitting radionuclides can be expected to be the main contributors to limiting conditions on liquid effluent concentrations, as established in Technical Specification 5.5.3.b and ODCM, Normal Condition 13.1.1. Note that including the non-gammas (excluding tritium) in the evaluation results in a higher effective EC value.Therefore, under conditions of elevatedeffluent levels, the main contributor to the limiting conditions of the liquid effluent concentration would be the gamma-emitting radionuclides.

The factor of six (6) conservatism in the effective EC determination (discussed above) provides adequate consideration for the contribution from non-gamma emitting radionuclides, and provides a conservative basis for establishing an alarm setpoint consistent with the requirements of Technical Specification 5.5.3.b and ODCM Normal Condition 13.1 .1.The Heating Boiler Blow Down and Turbine Building Sump are discharged to the lake with no installed radiation monitor. Using the default effective EC value of 1.OE-06 ltCi/ml for increased monitoring is consistent with the ODCM methodology if an installed radiation monitor was available.

(%VDNR) to M.Vandenbusch dated June 13, 1991 In reference 1, pursuant io the regulation of 10 CFR 20.302, Wisconsin Public Service Corporation (WPSC) requested authorization for the alternative disposal of very-low-level radioactive materials from the Kewaunee Nuclear Power Plant. In reference 2, the US NRC identified additional questions that needed to be addressed in order to complete their review.Attachment I provides our response to the questions.

WPSC requested the State of Wisconsin Department of Natural Resources (WDNR) to review the disposal options for the service water pretreatment lagoon sludges. in reference 3, the WDNR completed a review of the most appropriate on site disposal methods for the slightly contaminated service water pretreatment lagoon sludges. The two proposed methods that the WDNR evaluated included in-situ.capping of the sludge in the wastewater treatment lagoon and on site landspreading.

In Attachment I, Appendix A, WPSC evaluated the on site landspreading D-3 KEWAUNEE POWER STATION OFFSITE DOSE CALCULATION MANUAL ODCM App-D Revision 14 April 18, 2012 Document Control Desk October 17, 1991 Page 2 application which is our preferred disposal method. WPSC does not intend to utilize the in-situ capping of the sludge in the lagoon at this time. However, in the letter the WDNR agreed that either disposal method was acceptable provided:-if the material is to be left in the lagoon, it would be capped in. accordance with Wisconsin State statutes.-if the on site landspreading option is utilized, the material would be spread by either disking into the soil or by spiking into the ground.WPSC will abide by the WDNR landspreading requirements which include locational and performance standards.

1) Letter from K. H. Evers to Document Control Desk dated September 1, 1989.I NRC Question #1 On page 4 of your submittal, the average input to the Sewage Treatment System is approximately 11,000 gallons per day. In the Final Environmental Statement, this system is to be operated below its design capacity of 9,000 gallons per day. Discuss this deviation from the design capacity, and provide information to justify the higher output for this system.WPSC Response The original Sewage Treatment System installed at the Kewaunee Nuclear Power Plant (KNPP) was replaced in 1986 with a higher capacity system. The original system was designed for an onsite work force of around 150 people.It was a limited capacity aerobic treatment system which included the onsite lagoon for additional retention.

Because of this limited capacity and more stringent conditions on system effluent to Lake Michigan, an aerobic digester I system was installed, which has a higher capacity, and uses current technology.

The estimated input volume to the Sewage Treatment System used in the September

12. 1989 application was 11,000 gallons per day. This value was based on past operating data. The increase in influent from the original design basis included in the Final Environmental Statement is due mainly to an increase in the number of individuals and facilities (e.g., training and simulator building) located onsite. Design changes to the system were I required to accommodate these new facilities.

I D-6 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Document Control Desk October 17, 1991 Attachment I, Page 2 The current volumes of sewage sludge were used as the basis for the potential dose analysis and corresponding radionuclide concentration limits. This increase has no significant effect on the dose modeling. (Refer to the response to NRC Question #2, below.)NRC Question #2 Provide information regarding how the disposal plan assures that the annual dose to any exposed individual will be kept b~elow I mrem per year.WPSC Response The dose pathway modeling used for determining the radioactive material concentration limits was based on NRC modeling.

The computer code IMPACTS-BRC was used as the basis for calculating the potential doses from the alternative disposal methods, This modeling includes reasonable conservative exposure pathway scenarios for the various disposal methods.Administrative controls will be established to ensure that the actual disposal of any slightly contaminated materials from KNPP are within the bounds of the evaluation.

Samples from each of the waste streams will be collected and analyzed by gamma spectroscopy prior to release for disposal.

A system lower limit of detection (LLD) of 5E-07 jtCi/ml for the principal gamma emitting radionuclides will be required.

This LLD ensures the identification of any contaminated materials at a fraction of the allowable concentration limits for the alternative disposal.The results of these analyses will be used to ensure that any detectable levels of radioactive material are within the limits for alternative disposal.

Any materials with levels of radioactive material above the concentration limits D-7 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Document Control Desk-October 17, 1991 Attachment 1, Page 3 (and of plant origin) will be treated as a radioactive waste and appropriately controlled.

Records will be maintained to ensure that the cumulative disposal of any U contaminated materials are maintained within the bounds of the evaluation.

In addition to a comparison of the individual radionuclide concentration limits, a 3 record of the total amount of radioactive material disposed of will be maintained.

Cumulative totals will be maintained to ensure that the total activity does not exceed the quantity assumed in the derivation of the limits.In developing the concentration limits presented in Table I of reference 1, it I was assumed the total annual design basis volume of 27,000 :ft 3 would be contaminated at the derived limit. The dose commitment from each radionuclide was individually evaluated as if it were the only radioactive material present. To determine if a mixture of radionuclides meets the limit, the sum-of-the-fractions rule should be applied (i.e., the sum of each radionuclide's concentration divided by its limiting concentration must be less 3 than one)..The concentration limits of Table 1 of reference I also have an implied total activity I limit. This limit is determined by multiplying the individual radionuclide concentration limit by the total estimated waste volume of 27,000 ft3. These total I activity limits are presented in Table A of this response, for each radionuclide individually.

For a mixture of radionuclides, a total. annual activity limit may be 3 determined by normalizing the concentrations so that the sum-of-the-fractions for the mixture equals one (1). These resultant adjusted concentrations may be multiplied by the 27,000 ft 3 waste volume to determine the corresponding toal activity limit of the mixture. , D-8 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Document Control Desk October 17, 1991 Attachment 1, Page 4 A Disposal Log will be maintained on a calendar year basis for all disposals of any very-low-level radioactive materials.

The log will contain as a minimum the following information:

Disposal location-Description of waste* Shipmentldisposal date* Waste volume* Radionuclide concentrations (gamma emitters)* Year-to-date radionuclide activity-Year-to-date waste volume In addition to the above Disposal Log, a record file will be kept for each individual disposal.

Sample gamma spectroscopy results-Identified radionuclide concentrations and total activity NRC Question #3 Revise Appendix B, Section A of your submittal, "Radiation Exposure During Transport," by adding the cumulative dose to the exposed population per reactor year for both the transportation worker and the general public (onlookers along mute).\VPsC Response The potential exposure to the general public (onlookers along route) is modeled by the IMPACTS-BRC code. As addressed in NUREG/CR-3585, this modeling is based on an integration of the source strength, an assumed D-9 m KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 m April 18, 2012 Document Control Desk 3 October 17, .1991.Attachment 1, Page 5 3 population density along route and vehicular speed. For a conservative evaluation of the potential exposure to the general public from the transport of I the KNPP waste, a population density of 610 persons/mi 2 was assumed. This value is conservative for the KNPP site area where the average population i density is less than 53 persons/mi 2.A transport distance of 45 miles was assumed. The IMPACTS-BRC modeling assumes five (5) tons of material are i transported per shipment.

For the assumed KNPP waste volume, this shipment weight translates into a total of 167 shipments per year. With a m vehicular speed of 20 miles per hour, the resultant total population exposure time is 375 person-hours per year. At the concentration limits established for m the alternative disposal, the potential onlooker doses during transport will be less than 0.01 person-rem.per year. For the modeling of the exposure to the i transport worker, the IMPACTS-BRC model assumes two drivers per vehicle.As presented in the September 12, 1989 submittal, the maximum dose to the 3 driver is less than I. mrem per year (<0.001 rem/yr). Therefore, the total collective dose to the transport workers will be twice the individual dose, i.e., m less than 0.002 person-tern.

Including the population dose of <0.01 person-rem per year, the total collective dose to both the transport workers and the population is less than 0.02 person-rem (0.002 person-rem

+ 0.01 person-rem

< 0.02 person-rem).

m For the disposal of the existing 15,000 ft 3 of contaminated sludges, the 3 population dose due to the transportation of the waste is calculated to be 0.0002 person-rem.

The estimated collective exposure to the transport worker 3 is 0.00007 person-rem.

The total collective dose due to transport of the waste is 0.00027 person-rem.

Land application is also an option for the disposal of the sewage sludges. Therefore, WPS .requests that the option for onsite disposal at the KNPP site by land application be included in the alternative disposal methods which was determined to be acceptable in our September 12, L989 submittal.

The potential pathways of exposure as evaluated in the September 12, 1989 submittal conservatively bound any additional pathways of exposure that would result from onsite land spreading of the waste. Attachment A to this response provides an overview of the land spreading disposal method. Also, the pathways of exposure applicable to the onsite land application are evaluated; and a comparison to the controlling pathways and radionuclide concentrations as presented in the September 12, 1989 submittal are discussed.

From a modeling standpoint, the two exposure scenarios , "Radiation Exposure During Transport" and "Radiation Exposure to Landfill Operator," appropriately characterize any potential exposure to workers involved with the land spreading of the waste. Thne other post-disposal exposure scenarios, "Intruder Scenario", "Intruder Well", and "Exposed Waste Scenario," as described in NUREG/CR.-3585 (and as discussed in Appendix C of the submittal) reasonably bound any potential exposures from either ground waste migration or post-release from the Kewaunee site. In no case is .there a higher potential for exposure from land application than the pathways and potential exposures that were used for the derivation of the limits for alternative disposal.Therefore, no revisions are needed to the radionuclide concentration limits proposed in the September 12, 1989 submittal to include the option for disposal by onsite land spreading of the waste.D-1 I KEWAUNEE POWER STATION OFFSITE DOSE CALCULATION MANUAL ODCM App-D Revision 14 April 18, 2012 Document Control Desk October 17, 1991 Attachment 1, Page 7 Table A Radionuclide Quantity Limits for Alternative Disposal Limiting Limiting Annual Nuclide Concentration Quantity (1Ci/nml) (Ci)H-3 9.65E-04 0.7382 C- 14 4.55E-05 0.0348 Cr-51 3.13E-04 0.2394 Mn-54 1.14E-05 0.0087 Fe-55 I AOOE-02 7.6500 Fe-59 7.90E-06 0.0060 Co-58 1. 16E-05 0.0089 Co-60 3.74E-06 0.0029 Ni-63 1.00E-02 7.6500 Sr-90 3.45E-03 2.6393 Zr-95 6.28E-06 0.0048 Nb-95 1.23E-05 0.0094 Mo-99 6.73E-05 0.0515 Tc-99 2,70E-04 0.2066 1-129 2.50E-06 0.0019 1-131 2.68E-05 0.0205 C,-134 6.16E-06 0.0047 Cs-137 1,71E-05 0.0131 Ba-140 5.52E-05 0.0422 La- 140 4.17E-06 0.0032 Transuranics.TRU (T'/2 > 5 yrs) 8.91E-05 0.0682 Pu-241 2.85E-03 2.1803 Cm-242 1.00E-02 7.6500 Assumes annual quantity of KNPP wastes is 27,000 ft 3 or 7.65E8 mils.I U I I I I I I I I I I I I I I I I I D-12 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Document Control Desk October 17, 1991 Attachment

1. Page 8 Appendix A Evaluation of Onsite Land Application for Alternative Disposal of Very-Low-Level Contaminated Materials Overview Land spreading of lagoon sludges onsite at the Kewaunee Nuclear Power Plant has been recommended by personnel from the Wisconsin Department of Natural Resources (DNR) as a desirable alternative to the use of the Kewaunee County Landfill for disposal.

This method of disposal is also a recommended practice for disposing of sewage treatment facility sludges.Therefore, WPS requests that this disposal method be included in the options available for the alternative disposal of very-low-level radioactively contaminated materials from KNPP.Description of Disposal Method The disposal of KNPP sludges will be performed by beneficial land application to a dedicated disposal area located onsice at the Kewaunee Nuclear Power Plant. Typical methods of land spreading will be employed.

KNPP sludges will be loaded onto appropriate vehicles (e.g., tanker truck, sludge spreader, etc.) and applied to the dedicated disposal area. The dedicated disposal area will be periodically plowed to a depth of 6 inches.Onsite disposal of water treatment and sewage sludges are allowed by EPA and State of Wisconsin Department of Natural Resources with the criteria and limits for land spreading being specified by the potential use of the land. The two land use criteria are 1) Agricultural land that covers any lands upon which food crops are grown or animals aie grazed for hurnan consumption, and 2) Non-Agricultural land that covers lands which do not represent ingestion pathways to man. To be conservative, the Agricultural Land Application limits of sludge contaminants will he applied to the KNPP wastes even though the less restrictive Non-Agricultural Land Application sludge contamination limits are allowed. Therefore, no more than 50 metric tons of sludge per heciare will be applied to the dedicated disposal site. This limit will ensure that any land application will not exceed the bounds of the dosc analysis as D-13 I KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Document Control Desk October 17, 1991 Attachment 1, Page 9 3 performed previously.

In addition, other limitations as applied to land application by the State of Wisconsin Department of Natural Resources will be followed (e.g., control of I runoff/erosion, proximity to well sresidences/surface water, etc.).Applicable Pathways of Exposure 3 The pathways of exposure applicable for land spreading are not appreciably different from the pathways evaluated for the disposal methods at the Kewaunee County Landfill or the 3 Green Bay Metropolitan Sewerage District facilities.

The major exposure pathways are discussed below: 3 Direct Exposure to Workers Any potential exposures to workers involved in the removal, transport and land spreading of the sludges are reasonably bound by the evaluation of the exposure to the transport worker in the September 12, 1989 submittal.

The I transport worker has been assumed to be exposed for 460 hours0.00532 days 0.128 hours 7.60582e-4 weeks 1.7503e-4 months per year at one (1) meter from unshielded waste. For the land spreading of these wastes, 3 it is estimated that the total exposure time for the removal and disposal of the lagoon sludges will require 'no longer than a three week period per year (i.e., 3 120 hours0.00139 days 0.0333 hours 1.984127e-4 weeks 4.566e-5 months ).The potential exposure to a worker onsite after land spreading, has been 1 estimated at no more that 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months per year. Such an individual would be involved in land maintenance activities, such as plowing and mowing. As modeled in the September 12, 1989 submittal, an exposure of 2000 hours0.0231 days 0.556 hours 0.00331 weeks 7.61e-4 months per year to the landfill operator has been assumed. For this exposure, the KN"PP3 materials are mixed with other landfill waste: a 1:13 mixing of KNPP materials to other waste is assumed. This mixing is not significantly different 3 from the type of mixing that will occur in the field with the sludges being D-14 I KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Document Control Desk October 17, 1991 Attachment 1, Page 10 plowed into the soil to a depth of six (6) inches. With a land spreading of 50 metric tons per hectare per year, a mixing ratio of 1:30 will be achieved.Therefore, the resultant dose to the exposed worker would be less than the I mrem per year dose to the transport worker as evaluated in the September 12, 1989 submittal.

Post Disposal Exposure -Intruder Scenario The IMPACTS-BRC model, as applied to the disposal of the KNPP waste, assumes a loss of institutional controls 10 years after closure of the site (See Appendix B of the September 12, 1989 submittal).

An individual is assumed to reside in a house built on the disposal area. This individual receives a direct exposure (from the uncovered waste), an inhalation exposure (from resuspension), and an ingestion exposure (from growing 1/2 of his food crops). For modeling purposes, it is assumed that the waste is mixed at a ratio of 1:13 with other soils during the resident's construction process.The onsite land application of KNPP waste will be limited by the Agricultural Land Application sludge concentrations even though the less restrictive Non-Agricultural Land Application sludge concentrations are applicable since a "dedicated land disposal" site will be used (i.e., no crops will be grown on the disposal site).Therefore, provided the KNPP waste does not exceed the Non-Agricultural maximum sludge concentrations for heavy metal or organic chemicals, unlimited application of waste to the dedicated land disposal site is allowed. However, to be conservative, the land application of KNPP wastes will be limited to 5 metric tons per hectare per year.The intruder scenario as evaluated in the September 12, 1989 submittal conservatively bounds this exposure pathway for the on-site land spreading.

D-15 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Document Control Desk i October 17, 1991 Attachment 1, Page 11 I Post Disposal -Intruder Well i The intruder well pathway for onsite land disposal is essentially the same as the I intruder well pathway as evaluated by the IMPACTS-BRC model. It is conservatively assumed that the well is located at the edge of the disposal site. As modeled, locating i the well at the disposal site edge in "downstream flow" direction maximizes the calculated hypothetical dose. (Additional discussion of this modeling is presented in 3 NTJREG/CR-3585, Volume 2).The potential dose for the intruder well scenario for the land spreading disposal would be less than 0.001 mrem per year. The modeling as presented in the September 12, 3 1989 submittal reasonably bounds any hypothetical well water exposure pathway.In summary, the modeling of the exposure scenarios, as presented in the September 1 12, 1989 submittal, conservatively bounds the hypothetically exposures for the on-site land spreading.

In no case is it likely that any individual, either on-site or off-site, will receive a dose in excess of I mrem per year from the disposal of the slightly contaminated materials.

The 15,000 cubic feet of contaminated sludge identified in the request contains a total radionuclide inventory of 0.17 mCi of Cesium-137 and Cobalt-60.

In its submittal, the licensee addres;ed specific information requested in accordance with 10 CFR 20.302(a), provided a detailed description of the licensed material, thoroughly analyzed and evaluated the information pertinent to the effects on the environment of the proposed disposal of licensed material, and co,-mitted to follow specific p'rocedures to minimize the risk of unexpected exposures.

2.0 DESCRIPTI1rIi

OF HtkSTE During the normal operation of Kewaunee, the potential exists for in-plant process streams which are not normally radioactive to become contaminated with very low levels of radioactive materials.

These waste streams are normally spara.t4d from the radioactive streams. However, due mainly to infrequent, minor svytem leaks, and anticipated operational occurrences, the potential exists for these systems to become slightly cuntaminated.

At Kewaunee.

the see¢66daey system demlneralizey resins, the survice watew pre-treatment system sludges, the make-up water system resins, and the sewage treatment plant sludges are waste streams that have the potential to become contamainated at very low levels.D-19 1 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 I April 18, 2012-2 -I Ouri. .the yearly testing of a batch of pre-treatm.en..t sludge, it was found that aproximately 15,000 cubic feet of sludge had been contaminated with Cs-137 and Co-60.3.0 PROPOSED DISPOSAL METHOD 3 WPSC plans to dispose of +/-he 15,000 cubic feet of contaminated sludge cnsize pursuant to 10 CFR 20,302. The sludge is currently contained in an cnsite lagoon at the KNPP sewage treatment facility.

The disposal of the sludge wili be by land application to an area located onsite at KNPP, as shown in I Figure 1. The area will be periodically plowed to a depth of 6 inches.Table i lists the principal nuclides identified in the sludge. The activity is based on measurements made in 1989. The radionuclide half-lives, which are I dominated by 30-year Cs-137, meet the staff's 10 CFR 20.30Z guidelines (reference G), which apply to radlonuclides with half-lives less th-.n 35 years.Nuclide Total Activity (mCi)Co-60 0.076 3 Cs-137 0-094 0.170 3 4.0 RA[) IOLOG ICAL IMPACT;The licensee has evaluated the following potential exposure path)ways to members of the general public from the radionuclides in the sludge: (1) I external exposure caused by groundshine from the disposal site; (2) internal exposure from inhalation of re-suspended radionuclides; and (3j interna!exposure from ingesting ground water. The staff has reviewed the licensee's calculational methods and assumptions and finds that they are consistent with NRC Regulatory Guide 1. 10, "Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I," Revision 1, October 1977. The staff finds the assessment methodology acceptable.

5 Table 2 lists the doses calculated by the licensee for the maximally exposed member of the public based on a total activity of 0.170 mki disposed of in the current year, as well as the cumulative impact of similar disposals during subsequent years. For any repetitive disposals, the licensee must reapply to I the HRC when a particular disposal would exceed the following boundary conditions, (1) the annual disposal must be less than a total activity of 0.2 mCi; (2) the whole body dose to the hypothetical maximally exposed individual must be less than 0.1 mrem/year; and (3) the disposal must be at the same site as described in Figure 1.D-20 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012 Whole Body Dos kceivOd by Maximally Exposed Individual Pathway (mrem/year)

Such a dose is a small fraction of the 300 mrem received annually by members of the general public from sources of natural background radiation.

The guidelines used by the NRU staff for onsite disposal of licensed niaterial are oresented in lable 3, along with the staff's evaluation of how each guideline has been satisfied.

The licensee's procedures and commitments as documented in the submittal are acceptable, provided that they are permanently Incorporated into the licensee's Offsite Dose.

1.0 INTRODUCTION

By letter dated June 23, 1994, and as supplemented on June 29, 1994, Wisconsin Public Service Corporation (the licensee) requested approval to use another onsite area for the disposal of contaminated waste sludge in addition to the location approved by the NRC on June 17, 1992.2.0 EVALUATION A Safety Evaluation (SE) dated June 17, 1992, approved the licensee's request pursuant to 10 CFR 20.302 for the disposal of IS,000 cubic feet of contaminated waste :sludge by land application at the Kewaunee Nuclear Power Plant (KNPP) at a specific onsite location.

The SE imposed the following boundary conditions:

1. The annual disposal must be less than a total activity of 0.2 mCi.2. The whole body dose to the hypothetical maximally exposed individual must be less than 0.1 mrem/year.

3. The disposal must be the same site.The site designated in the SE was an unused area adjacent to the onsite lagoon at the KNPP sewage treatment facility.

In 1993, approximately 7500 cubic feet of the original 15,000 cubic feet of contaminated sludge was spread on that location.

The licensee has now proposed to dispose of the remaining contaminated sludge at another onsite location northwest.

of the plant (see Attachment).

The licensee has coiimitted that the new disposal.

location will meet all the radiological boundary conditions contained in the SE for the 10 CFR 20.30Z application approved on June 17, 199Z. Additionally, the licensee has stated that this additional disposal site will meet all applicable Wisconsin Department of Natural Resources (WDNR) application requirements (i.e., sludge application rate and frequency of spreading rate), in addition to WMIR landspreading requirements regarding location and performance standards that were required at the original disposal site, D-27 KEWAUNEE POWER STATION OFFSITE DOSE CALCULATION MANUAL ODCM App-D Revision 14 April 18, 2012-2-3.0 CONCLUS[ON The staff finds the licensee's proposal to dispose of the low-level radioactive waste sludge in the additional onsite location to be within the radiological boundary conditions approved In the June 17, 1992, SE and is therefore acceptable.

In a Safety Evaluation (SE) dated June 17, 1992, the N(RC approved the licensee's request pursuant to 10 CFR 20.302 (new 10 CFR 20.2002) for the disposal of 15,000 U cubic feet of contaminated waste sludge by land application at the Kewaunee Nuclear Power Plant (KNPP) Iocation.

The SE imposed the following boundary conditions:

1. The annual disposal must be less than a total activity of 0.2 mCi.2. The whole body dose to the hypothetical maximally exposed individual must be less than 0.1 mrem/year.

3 3. The disposal must be at the same site.The licensee completed the disposal of the contaminated waste sludge discussed in the SE dated June 17, 1992. The licensee is now requesting authorization I to dispose of additional contaminated waste sludge within the boundary conditions of the previously approved disposal.3.0 EVALUATION 3 The 1 icensee has proposed to dispose of approximately 6000 gallons (800 cubic feet) of sewage sludge similar to the material approved for disposal In the SE dated June 17, 1992. The principal radionuclides identified in the waste sludge and their activity based on measurements In May 1995 are: Co-58, D D-32 1 KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 April 18, 2012-z-0.0009 mCi; Co-60, 0.0008 mci; and Cr-51, 0.0006 mCi. The total combined activity Is 0.0023 mCi. This activity is well below the boundary value of 0.2 mCi. Additionally, Cr-51 with it short half-life (27.7 day) will have undergone significant decay froa its initial value of 0.0006 mCi.The licensee has comitted that the new disposal will meet all the radiological boundary conditions, on a cumulative basis, contained In the SE for the 10 CFR 20.302 application approved on June 17, 1992. Additionally, the licensee has stated that all applicable permits for this disposal have been obtained from the Wisconsin Department of Natural Resources.

4.0 CONCLUSION

The staff finds the licensee's proposal to dispose of.the low-level radioactive waste sludge pursuant to 10 CFR 20.2002. on the licensee's site (see Attachment), is within the radlological boundary conditions approved in the June 17, 1992, SER and is therefore acceptable.

1.0 INTRODUCTION

By letter dated December 1D, 1996, Wisconsin Public Service Corporation (the licensee) requested that the U.S. Nuclear Regulatory Commisslon (NRC) review its determination that NRC approval, pursuant to 10 CFR 20.2002, for the onsite disposal of. contaminated sludge at the Kewaunee Nuclear Power Plant (KNPP) is not required, provided such disposals are conducted within the limits and bounding conditions approved by the NRC in its June 17, 199Z, Safety Evaluation (SE).

2.0 BACKGROUND

In a letter dated September 12, 1989, the licensee requested authorization for the alternate disposal of sludge contaminated with licensed radioactive material.

In an SE dated June 17, 1992, the NRC approved the licensee's request pursuant to 10 CFR 20.302 (new 10 CFR 20,2002) for the disposal of 15,000 cubic feet of contaminated waste sludge by land application at the KNPP location.

The SE imposed boundary conditions as follows: 1. The annual disposal must be less than a total activity of 0.2 mCI;2. The whole body dose to the hypothetical maximally exposed individual must be less than 0.1 mrem/year; and 3. The disposal must be at the same site.The SE also stated that for any repetitive disposals, the licensee must reapply to the NRC when a particular disposal would exceed the boundary conditions.

3.0 EVALUAtION

The licensee has determined that NRC approval for future onsite disposals of sludge contaminated with licensed radioactive material is not required provided the disposals comply with the limits and conditions of the SE issued on June .17, 1992. The licensee has also developed a sludge sampling and analysis procedure that implements the guidance contained in NRC Information D-37 I KEWAUNEE POWER STATION ODCM App-D OFFSITE DOSE CALCULATION MANUAL Revision 14 I April 18, 2012 1 Notice 88-22. Specifically, the licensee's procedure will require the 3 analysis of sludge samples using a detection system design and operating characteristics that yield a lower limit of detection for Co-58, Co-60, Cs-134, and Cs-137 consistent with measurements of environmental samples. The licensee has provided a site map (attached) that specifies the acceptable I onsite disposal areas for the contaminated sludge.

4.0 CONCLUSION

I The staff agrees with the licensee's determination that additional onsitce disposals of contaminated sludge, which are conducted within the bounding limits and conditions contained in the June 17, 1992, SE and within the areas spec.ified in the attached site map, do not re~quire specific NRC approval.

1.1 Prttpose

The purpose of this document is to define the Radiological Environmental Monitoring Program (REMP) for the Kewaunee Power Station (KPS). The REMP is required by ODCM, 13.5 This document is known as the Radiological Environmental Monitoring Manual (REMM) and is intended to serve as a tool for program administration and as a guidance document for contractors which implement the monitoring program.1.2 Scope This program defines the sampling and analysis schedule which was developed to provide representative measurements of radiation and of radioactive materials in those exposure pathways and for those radionuclides that lead to the high potential radiation exposures of MEMBERS OF THE PUBLIC resulting from plant operation.

This monitoring program implementsSection IV.B.2 of Appendix I to LOCFR Part 50 and thereby verifies that the measurable concentrations of radioactivity and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.

Guidance for the development of this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring.

This program has been developed in accordance with NUREG 0472.The program will provide field and analytical data on the air, aquatic, and terrestrial radioecology of the area near the Kewaunee Power Station so as to: 1. Determine the effects of the operation of the Kewaunee Power Station on the environment;

2. Serve as a gauge of the operating effectiveness of in-plant control of waste discharges; and 3. Provide data on the radiation dose to the public by direct or indirect pathways of exposure.1.3 Implementation This document is considered, by reference, to.be part of the Offsite Dose Calculation Manual. This is as required by KPS TS 5.5.1. The REMM is controlled as a separate document for ease of revision, use in the field and use by contractors.

This format was approved by the NRC as part of TS Amendment No. 64, which provided Radiological Effluent Technical Specifications (RETS) for KPS.1-I I KEWAUNEE POWER STATION REMM 1.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 I September 6, 2012 The REMP is setup to be implemented by a vendor and controlled by KPS in accordance with 3 Nuclear Administrative Directive NAD-0.1.20, "Radiological Environmental Monitoring Program." Monthly reviews of the vendor's progress report are checked and approved by KPS in *accordance with Surveillance Procedure SP-63-276.

Annual reviews and submittals of the vendor'sI report and raw data are checked and approved by KPS in accordance with Surveillance Procedure SP-63-280.

All sample collection, preparation, and analysis are performed by the vendor except where noted. Surveillance Procedure SP-63-164 outlines the environmental sample collection I performed by KPS. Current vendor Quality Control Program Manuals and implementing procedures shall be kept on file at KPS.Periodic reviews of monitoring data and an annual land use census will be used to develop modifications to the existing monitoring program. Upon approval, these modifications will be incorporated into this document so that it will accurately reflect the current radiological environmental monitoring program in effect for KPS.The remainder of this document is divided into two sections.

The first section, 2.0 REMP 3 Requirements, describes the different TS and REMM requirements associated with the REMP. The second section, 3.0 REMP Implementation, describes the specific requirements used to implement the REMP. 5 1-2 KEWAUNEE POWER STATION REMM 2.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 September 6, 2012 2.0 REMP Requirements KPS TS Amendment No. 104 implemented the guidance provided in Generic Letter 89-01,"Implementation of Programmatic Controls for Radiological Effluent Technical Specifications (RETS).", These changes included: 1. Incorporation of programmatic controls in the Administrative Controls section of the TS to satisfy existing regulatory requirements for RETS, and 2. Relocation of the procedural details on radioactive effluents monitoring, radiological environmental monitoring, reporting details, and other related specifications from the TS to the ODCM.Relocating the procedural details to the ODCM allows for revising these requirements using the I OCFR50.59 process instead of requiring prior NRC approval using the TS Amendment process.The RETS requirements were incorporated verbatim into the ODCM, Revision 6. Several of these requirements pertain only to the environmental monitoring program and therefore have been relocated into this document (REMM, Revision 3 and 4) and are identified as REMM requirements.

2.1 ODCM 13.5 Requirements ODCM 13.5 provides the programmatic control, which requires a program to monitor the radiation and radionuclides in the environs of the plant. This is the reason for the existence of the REMP.ODCM 13.5, also provides the programmatic control which requires: a. The program to perform the monitoring, sampling, analysis, and reporting in accordance with the methodology and parameters in the ODCM, b. A land use census to be performed, and c. Participation in an Interlaboratory Comparison Program.The details of each requirement are described in the REMM requirements stated below.Technical Specification

5.6.1 requires

an "Annual Radiological Environmental Operating Report," be submitted to the NRC each year. The specific contents of this report are detailed in REMM 2.4.1. Additional specific reporting requirements are listed in the other REMM requirements.

This monitoring program implementsSection IV.B.2 of Appendix I to 1 OCFR Part 50 and thereby supplements the radiological effluent monitoring I program by verifying that the measurable concentrations of radioactive materials and levels of radiation are not higher than expected on the basis of the effluent measurements and the modeling of the environmental exposure pathways.

Guidance for this monitoring program is provided by the Radiological Assessment Branch Technical Position on Environmental Monitoring.

Program changes may be initiated based on operational experience.

The required detection capabilities for environmental sample analyses are tabulated in terms of the 3 lower limits of detection (LLDs). The LLDs required by Table 2.3.1-A are considered optimum for routine environmental measurements in industrial laboratories.

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

Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.A., "Limits for Qualitative Detection and Quantitative Determination

U I I I I I I I I I I I I I 1 I 2-8 KEWAUNEE POWER STATION REMM 2.2.2 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 September 6, 2012 BASES This requirement is provided to ensure that changes in the use of areas at and beyond the SITE BOUNDARY are identified and that modifications to the radiological environmental monitoring program are made if required by the door-to-door survey, from aerial survey or from consulting with local agricultural authorities.

This census satisfies the requirements of Section IV.B.3 of Appendix I to 10CFR Part 50. Restricting the census to gardens of greater than 50 m 2 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 produce the quantity (26 kg/yr) of leafy vegetables assumed in Regulatory Guide 1.109 for consumption by a child. To determine this minimum garden size, the following assumptions were made: 1. 20% of the garden was used for growing leafy vegetation (i.e., similar to lettuce and cabbage), and 2.

Discussion 3 KPS TS 5.6.1 provides the programmatic control, which requires that an Annual Radiological Environmental Operating Report be submitted to the NRC. It also states that this report shall include summaries, interpretations, and analysis of trends of the results of the REMP for the reporting period.The procedural details of this report are included in this requirement.

REMM 2.2.1/2.3.1, 2.2.2/2.3.2, and 2.2.3/2.3.3 also include specific reporting requirements.

These requirements I reference this REMM, along with TS 5.6.1, as the method for reporting deviations from the current program during the reporting period, and require that this information be included in the Annual Radiological Environmental Operating Report.2-12 KEWAUNEE POWER STATION REMM 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 September 6, 2012 3.0 REMP Implementation The Radiological Environmental Monitoring Program for KPS is under the direction of a Contracted Vendor (CV). This section describes this program, as required by REMM 2.2.1 and the process the CV uses to perform it.3.1 Sampling Requirements Table 2.2.1-A identifies the various samples required by the REMP. Identified in the "available sample locations" column in Table 2.2.1-A are the sample locations selected, in conjunction with the vendor, to meet or exceed the REMP requirements.

Table 2.2. 1 -B includes the same requirements as in Table 2.2.1-A but presents the information in a different format by identifying the type of samples required at each location and the collection frequency.

Table 2.2.1-C identifies the location and description of each sample location.

Figure 1 shows the physical location of each sample point on an area map.3.2 Analysis Methodology Analytical procedures and counting methods employed by the CV will follow those recommended by the U.S. Public Health Service publication, Radioassay Procedures for Environmental Samples, January 1967; and the U.S. Atomic Energy Commission Health and Safety Laboratory, HASL Procedures Manual (HASL-300), 1972. The manual is also available on-line at www.eml.st.dhs.gov/publications/procman.

Updated copies will be maintained in KPS's vault.3.3 Detection Capability (LLD) Requirements The required detection capabilities for environmental sample and analysis are tabulated in terms of lower limits of detection (LLDs) in Table 2.3.1-A. The LLDs required by Table 2.3.1-A are considered optimum for routine environmental measurements in industrial laboratories.

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

Detailed discussion of the LLD, and other detection limits, can be found in HASL Procedures Manual, HASL-300 (revised annually), Currie, L.A., "Limits for Qualitative Detection and Quantitative Determination

-Application to 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).3-1 I KEWAUNEE POWER STATION REMM 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 I September 6, 2012 3.4 Contracted Vendor Reporting Requirements Monthly Progress Reports Monthly progress reports will include a tabulation of completed analytical data on samples obtained during the previous 30 day period together with graphic representations where trends are evident, and the status of field collections.

One copy of the reports will be submitted within 30 to 60 days of the 3 reporting month.Annual Reports 3 Annual reports will be submitted in two parts. Part I, to be submitted to the NRC, will be prepared in accordance with NRC Regulatory Guide 4.8. It will contain an introductory statement, a summary of results, description of the program, discussion of the results, and summary table. Part II of the annual report will include tables of analytical data for all samples collected during the reporting period, together with graphic presentation where trends are evident and statistical evaluation of the results. Gamma scan data will be complemented by figures of representative spectra if requested by KPS. Draft copies of each annual report will be due 60 days after completion of the annual period.After final review of the draft document, one photoready copy of the revised annual report will be sent to KPS for printing.Non-Routine Reports 5 If analyses of any samples collected show abnormally high levels of radioactivity, KPS will be notified by telephone immediately after data becomes available.

Action Limits The CV will report any radioactive concentrations found in the environmental samples which exceed i the reporting levels shown in Table 2.2.1 -D, CV to KPS column. These levels are set below the NRC required reporting levels (KPS to NRC column) so actions can be initiated to prevent exceeding the NRC concentration limits. i 3-25 KEWAUNEE POWER STATION REMM 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 September 6, 2012 3.5 Quality Control Pr-ogram To insure the validity of the data, the CV maintains a quality control (QC) program, which employs quality control checks, with documentation, of the analytical phase of its environmental monitoring studies. The program is defined in the CV's QC Program Manual, and procedures are presented in the CV QC Procedures Manual. The program shall be reviewed and meet the requirements of Regulatory Guide 4.15 and 1 OCFR2 1. All data related to quality control will be available for review by Dominion Energy Kewaunee upon reasonable prior notification.

Proprietary information will be identified so that it may be treated accordingly.

Updated copies of the Quality Control Program Manual and the Quality Assurance Program Manual will be maintained in KPS's vault.3.6 Sample Descriptions A description of each of the samples required by this. program follows: Airborne Particulates Airborne particulates are collected at six locations (K-lf, K-2, K-8, K-31, K-41, and K-43) on a continuous basis on a 47 mm diameter membrane filter of 0.8 micron porosity at a volumetric rate of approximately one cubic foot per minute (CFM). The filters are changed weekly, placed in glassine protective envelopes, and dispatched by U.S. Mail to the CV for Gamma Isotopic Analysis.Filter samples are analyzed weekly for gross beta activity after sufficient time (usually 3 to 5 days)has elapsed to allow decay of Radon and Thoron daughters.

If gross beta concentration in air particulate samples are greater than ten (10) times the yearly mean of the control samples, gamma isotopic analysis shall be performed on the individual samples. Quarterly composites from each location receive Gamma Isotopic Analysis using a Germanium detector.

All identifiable gamma-emitters are quantified.

Reporting units are pCi/m 3.Airborne Iodine All air samplers are equipped with charcoal traps installed behind the particulate filters for collection of airborne 1-13 1. The traps are changed once every week. Iodine-131 is measured by Gamma Isotopic Analysis.Periphyton (Slime) or Aquatic Vegetation Periphyton (slime) or aquatic plant samples are collected at or near locations used for surface water sampling.

They are collected twice during the year (2nd and 3rd quarter), if available.

The samples are analyzed for gross beta activity and, if available in sufficient quantity, for Sr-89, Sr-90, and by Gamma Isotopic Analysis.

Reporting units are pCi/g wet weight.3-3 I KEWAUNEE POWER STATION REMM 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 I September 6, 2012 Fish I Fish are collected three times per year (second, third, and fourth quarters) near the discharge area (K-ld). Flesh is separated from the bones and analyzed for gross beta activity and by Gamma I Isotopic Analysis.

The bones are analyzed for gross beta activity and Sr-89 and Sr-90. Reporting units are pCi/g wet weight. 3 Domestic Meat Domestic meat (chickens) may be collected once a year during the 3rd quarter, from three locations I in the vicinity of the plant (K-24, K-29, and K-32). Samples may not be available every year at every location due to farmer preference.

At least one control and one indicator should be collected.

The flesh is analyzed for gross alpha, gross beta, and by Gamma Isotopic Analysis to identify and I quantify gamma-emitting radionuclides.

Reporting units are pCi/g wet weight.Ambient Radiation 3 Two packets of thermoluminescent dosimeters (CaSO 4: Dy cards) are placed at twenty-two locations, six of which are air sampling locations (K-I f, K-2, K-8, K-31, K-41, and K-43), three of 3 which are milk sampling locations (K-3, K-5, and K-39), eight of which are ISFSI area locations (K-11 through K- 1s), and the remaining four locations are K -15, K- 17, K-27, and K-30. One packet is changed quarterly and one annually.

Annual TLDs will serve as an emergency set to be read when needed. They will be exchanged annually (without reading) if not read during the year. To insure the precision of the measurement, each packet will contain two cards with four dosimeters each (four sensitive areas each for a total of eight). For protection against moisture each set of cards is sealed in a plastic bag and placed in a plastic container.

Each card is individually calibrated for self-irradiation and light response.

Fading is guaranteed by the manufacturer (Teledyne Isotopes) not to exceed 20% in one year. Minimum sensitivity for the I multi-area dosimeter is 0.5 mR defined as 3 times the standard deviation of the background.

Maximum Error (I standard deviation)

-6 0 Co Gamma +/-0.2 mR or +/-3%, whichever is greater. The maximum spread between areas on the same dosimeter is 3.5% at 1 standard deviation.

Reporting units for TLDs are mR/91 days for quarterly TLDs and mR/exposure period for annual I TLDs.Tests for uniformity and reproducibility of TLDs as specified in ANSI N545-1981 and NRC I Regulatory Guide 4.13, are performed annually.I 3-4I KEWAUNEE POWER STATION REMM 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 September 6, 2012 Well Water One gallon water samples are taken once every three months from four off-site wells, (K- 10, K-11, K- 13, and K-38) and two on-site wells (K- 1 h and K- 1 g). All samples are analyzed for gross beta in the total residue, K-40, tritium, and by Gamma Isotopic Analysis.

Samples from one on-site well are analyzed for Sr-89, and Sr-90. Samples from K-lh and K-lg are also analyzed for gross alpha.Reporting units are pCi/I.Precipitation A monthly cumulative sample of precipitation is taken at Location K- 11. This sample is analyzed for tritium. Reporting units are pCi/l.Milk Milk samples are collected from three herds that graze within three miles of the reactor site (K-38, K-44, and K-34); from four herds that graze between 3-7 miles of the reactor site (K-3, K-5, K-35, and K-39); and one from a dairy in Green Bay (K-42), 28.1 miles from the reactor site.The samples are collected twice per month during the grazing period (May through October) and monthly for the rest of the year. To prevent spoilage the samples are treated with preservative.

All samples are analyzed by Gamma Isotopic Analysis and for iodine -131 immediately after they are received at the laboratory.

To achieve required minimum sensitivity of 0.5 pCi/l, iodine is separated on an ion exchange column, precipitated as palladium iodide and beta counted. Monthly samples and monthly composites of semimonthly samples are then analyzed for Sr-89 and Sr-90. Potassium and calcium are determined and the "'Cs/gK and 9°Sr/gCa ratios are calculated.

Reporting units are pCi/I except for stable potassium and calcium, which are reported in g/l.If milk samples are not available, green leafy vegetables will be collected on a monthly basis (when available) from Locations K-23A, K-23B, and K-26.Grass Grass is collected three times per year (2nd, 3rd, and 4th quarters) from the six dairy farms (K-3, K-5, K-35, K-34, K-38, and K-39) and from two on-site locations (K-lb and K-if). The samples are analyzed for gross beta activity, for Sr-89 and Sr-90, and Gamma Isotopic Analysis to identify and quantify gamma-emitting radionuclides.

Reporting units are pCi/g wet weight.Cattle feed Once per year, during the first quarter when grass is not available, cattle feed (such as hay or. silage)is collected from the six dairy farms. The analyses performed are the same as for grass. Reporting units are pCi/g wet weight.3-5 I KEWAUNEE POWER STATION REMM 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 I September 6, 2012 Vegetables and Grain I Annually, during the 3rd quarter, samples of five varieties of vegetables grown and marketed for human consumption are collected from K-26, depending upon the availability of samples. If samples are not available from this location, samples may be obtained from any local source so there is some sample of record. The location will be documented.

In addition, two varieties of grain or leafy vegetables from the highest predicted X/Q and D/Q, if available, are collected annually from the I farmland owned by Dominion Energy Kewaunee (K-23 a and b) and rented to a private individual for growing crops. The analyses performed are the same as for grass. Reporting units are pCi/g wet weight.Quarterly samples of eggs can be taken from K-24 and K-32. At least one control and one indicator should be collected.

The samples are analyzed for gross beta activity, for Sr-89 and Sr-90, and Gamma Isotopic Analysis to identify and quantify gamma-emitting radionuclides.

Reporting units I are pCi/g wet weight.Soil 3 Twice during the growing season samples of the top two inches of soil are collected from the six dairy farms and from an on-site location (K-if). The soil is analyzed for gross alpha and gross beta activities, for Sr-89 and Sr-90, and Gamma Isotopic Analysis to identify and quantify gamma-emitting manmade radionuclides.

Reporting units are pCi/g dry weight.Surface Water I Surface water is sampled monthly from Lake Michigan at the KPS discharge (K-Id), two samples (north and south ends), of Two Creeks Park, 2.5 miles south of the reactor site (K- 14a, K-14b). Samples are collected monthly at the Green Bay Municipal Pumping station between Kewaunee and Green Bay (K-9). Raw and treated water is collected.

Monthly samples are also taken, when available, from each of the three creeks (K-la, K-i b, K- 1 e) that I pass through the reactor site and from the drainage pond (K-1k) south of the plant. The samples are taken at a point near the mouth of each creek and at the shore of the drainage pond.The water is analyzed for gross beta activity in: a. The total residue, b. The dissolved solids, and 3 c. The suspended solids.The samples are also analyzed for K-40 and by Gamma Isotopic Analysis.

Quarterly composites from all locations are analyzed for tritium, Sr-89 and Sr-90. Reporting units are pCil.3-6 KEWAUNEE POWER STATION REMM 3.0 RADIOLOGICAL ENVIRONMENTAL MONITORING MANUAL Revision 19 September 6, 2012 Bottom Sediments Five samples of Lake Michigan bottom sediments, one at the discharge (K-Id), one from 500 feet north of the discharge (K-Ic), one from 500 feet south of the discharge (K- lj), and one at the Two Creeks Park (K-14), one at the Green Bay Municipal Pumping Station (K-9) are collected semi-annually (May and November).

The samples are collected at the beach in about 2-3 feet of water. All samples are analyzed for gross beta activity, for Sr-89 and Sr-90 and by Gamma isotopic Analysis.

Since it is known that the specific activity of the sediments (i.e., the amount of radioactivity per unit mass of sediment) increases with decreasing particle size, the sampling procedure will assure collection of very fine particles.

Reporting units are pCi/g dry weight.Ground Monitoring Wells Figure 2 shows the location of 14 installed groundwater monitoring wells. The wells and location are identified with a diamond shape in Figure 2. The wells are labeled MW (Monitoring Well) and AB (Auxiliary Building).

The Groundwater Protection Program consists of the 14 wells in addition to the two on-site wells already in the REMM (K-lg and K-lh).Results of analyses and a description of anyevent above Reporting Levels will be included in the Annual Radiological Environmental Operating Reportfor K- Ig, K-1 h and in the annual Radioactive Effluent Release Report for the other 14 wells.3-7 I I Table 2.2.1-A Radiological En viromnental Monitoring Program_Exposure Pathway Mininmum F Available Sample Sampling, Type of hCollection and And/Or Sample Required Samples a Locations h Analysis Frequency Analysis 1.

The samples listed in this column describe the minimum sampling required to meet REMP requirements.

b. Additional details of sample locations are provided in Table 2.2.1-C and Figure 1. The REMP requires that samples to be taken from each of the "available sample locations" listed (see section 3. 1). Deviations from the required sampling schedule will occur if specimens are unobtainable due to hazardous conditions, seasonal unavailability, malfunction of automatic sampling equipment and other legitimate reasons. If specimens are unobtainable due to sampling equipment malfunction, reasonable efforts shall be made to complete corrective actions prior to the end of the next sampling period.All deviations from the sampling schedule shall be documented, as required by REMM 2.4. l.c, in the Annual Radiological Environmental Operating Report. It is recognized that, at times, it may not be possible or practicable to continue to obtain samples of the media ofechoice at the most desired location or time. In these instances suitable alternative media and locations may be chosen for the particular pathway in question and appropriate substitutions made within 30 days in the REMM. The cause of the unavailability of samples for that pathway and the new location(s) for obtaining replacement samples will be identified in the Annual Radiological Environmental Operating Report.c. For the purposes of this table, each location will have 2 packets of thermoluminescent dosimeters (TLDs). The TLDs are CaSO4: Dy cards with 2 cards/packet and 4 dosimeters/card (four sensitive areas each for a total of eight dosimeters/packet).

The NRC guidance of 40 stations is not an absolute number. The number of direct radiation monitoring stations has been reduced according to geographical limitations; e.g., Lake Michigan.

The frequency of analysis or readout for TLD systems depends upon the characteristics of the specific system used and selection is made to obtain optimum dose information with minimal fading.d. The purpose of this sample is to obtain background information.

If it is not practical to establish control locations in accordance with the distance and wind direction criteria, other sites that provide valid background data may be substituted.

Airborne particulate sample filters shall be analyzed for gross beta radioactivity 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months or more after sampling to allow for radon and thoron daughter decay. if gross beta activity in air particulate samples is greater than ten times the yearly mean of control samples, gamma isotopic analysis shall be performed on the individual samples.f. Gamma isotopic analysis means the identification and quantification of gamma-emitting radionuclides that may be attributable to the effluents from the facility.g. The "upstream sample" shall be taken at a distance beyond significant influence of the discharge.

The "downstream" sample shall be taken in an area near the mixing zone.h. Ground water samples shall be taken when this source is tapped for drinking or irrigation purposes in areas where the hydraulic gradient or recharge properties are suitable for contamination.

i. In the event elevated analysis are reported by CV for gamma isotopic or tritium, a review will be conducted with the option to retest additional analysis for hard to detect isotopes or alpha emitters.

The additional test may include Fe-55, Ni-63, or alpha emitters anticipated on current plant conditions.

This list does not mean that only these nuclides are to be considered.

Other peaks that are identifiable, together with those of the above nuclides, shall also be analyzed and reported in the Annual Radiological Environment Operating Report.b. Required detection capabilities for thermoluminescent dosimeters used for environmental measurements are given in Regulatory Guide 4.13.c. The LLD is defined, for purposes of these requirements, as the smallest concentration of radioactive material in a sample that will yield a net count, above system background, that will be detected with 95% probability with only 5% probability of falsely concluding that a blank observation represents a "real" signal.For a particular measurement system, which may include radiochemical separation:

LLD = 4"66sb E x V x 2.22 x Y x exp(--yAt)

Where: LLD is the a priori lower limit of detection as defined above, as picocuries per unit mass or volume, Sb is the standard deviation of the background counting rate or of.the counting rate of blank sample as appropriate, as counts per minute, E is the counting efficiency, as counts per disintegration, V is the sample size in units of mass or volume, 2.22 is the number of disintegrations per minute per picocurie, Y is the fractional radiochemical yield, when applicable, ,y is the radioactive decay constant for the particular radionuclide, and At for environmental samples is the elapsed time between sample collection, or end of the sample collection period, and time of counting, Typical values of E, V, Y, and At should be used in calculation.

Rev. 19 Page 2 of 3 September 6, 2012 Table Notations for Table 2.3.1-A (con 't)It should be recognized that the LLD is defined as a priori (before the fact) limit representing the capability of a measurement system and not as an a posteriori (after the fact) limit for a particular measurement.

Analyses shall be performed in such a manner that the stated LLDs will be achieved under routine conditions.

Occasionally background fluctuations, unavoidable small sample sizes, the presence of interfering nuclides, or other uncontrollable circumstances may render these LLDs unachievable.

In such cases, the contributing factors shall be identified and described in the Annual Radiological Environmental Operating Report.d. If no drinking water pathway exists, a value of 3,000 pCi/l may be used.e. LLD for drinking water samples. If no drinking water pathway exists, the LLD of gamma isotopic analysis may be used.f. This is NOT a NUREG-0472 required value.
