SUMMARY

On October 22, 2012, Dominion made known the decision to permanently shut down the Kewaunee Power Station (KPS). On February 25, 2013, Dominion Energy Kewaunee (DEK) submitted a certification of permanent cessation of power operations pursuant to 10 CFR 50.82(a)(l)(i), stating that DEK has decided to permanently cease power operation of KPS on May 7, 2013. On May 15, 2013 the NRC docketed the certification for permanent removal of fuel from the reactor vessel pursuant to 10 CFR 50.82(a)(l)(ii). Therefore the 10 CFR Part 50 license no longer* authorizes KPS to operate the reactor or emplace or retain fuel in the reactor vessel, as specified in 10 CFR 50.82(a)(2). During 2015 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 Pathw;:iy-Organ Total Body Quarterly Limit (mRem) 7.5 Actual Dose (mRem) l.30E-04 (4th Quarter)

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, 2015. 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, major changes to the radioactive liquid and gaseous waste treatment systems, 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 evolutions at the Kewaunee Power Station. Page 3 of29

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 'concentrati6ns, dose rates and

            ,cumulative quarterly and annual doses. tqe ODCM methodology is acceptable for use
           *in demonstrating compliance with 10 CFR 20.i301/l302; 10 CFR 50, Appendix I; and 40CFR190.

2.0 GASEOUS EFFLUENTS 2.1 Lower Limits of Det~ction (LLD) for Gaseou~ Effluents Gaseous radioactive effluents are released in both the continuous mode and the batch mode. The auxiliary building stack is sampled continuou~ly for particulates, halogens and Strontium by l'.!-Il "off-line" sample traiU.

This stack is also gq1b-sampled weekly for gaseous gamma emitters and monthly for tritium. Batch releases are sampled prior fo release for principal gaseous and particulate gamma emitters, halogens and tritium.*

The LLD's for gaseous radio-analyses, as listed in Table 13.2J-1 of the Kewaunee ODCM are: Analysis LLD (µCi/ml) Gaseous Gamma Emitters 1.00E-04 Iodine 131 3;00E-12 Particulate Gamma Emitters 1.00E:.11 Particulate Gross Alpha l.OOE-11 Strontium 89, 90 l.OOE-'l l Noble Gases, Gross Beta or Gamma 1.00E~06 Tritium (H-3) l.OOE~06 The nominal "a priori" LLD values are shown below.

3.0 LIQIDD EFFLUENTS . 3.1 Lower Limits of Detection (LLD) for Liquid Effluents . Liquid radioactive effluents are released as both batch releases and continuous* releases .. Each batch is sampled prior to release and analyzed for gamma emitters and tritium. A fraction of each sample is retained for a monthly proportional composite which is then analyzed for Gross Alpha, Strontium 89, Strontium 90, Iron 55 and Nickel 63. The LLD's for liquid batch release radio-analyses, as listed in Table 13.1.1-1 of the Kewaunee ODCM are: Analysis LLD (µCi/ml) Principal Gamma Emitters 1.00 E-06 Iodine 131 1.00 E-06 Tritium (H-3) 1.00 E-05 Gross Alpha 5.00 E-07 Strontium 89, 90 5.00 E-08 Iron 55 1.00 E-'06 The actual obtained "a priori" LLD values for batch releases are shown below.

6. 7.1 The sample pump flow totalizer used for strontium sampling of the effluent from the auxiliary ventilation stack was found to be at zero flow on 5/31/2015. Sample flow volume was calculated manually using the start and stop time of the sample collection and then multiplying this vahie by the pump flow rate. The probable cause of the totalizer reading a zero value was loss of power due to electrical breaker cycling activities occurring five days earlier. CR5811l7.

SUMMARY

On October 22, 2012, Dominion made known the decision to permanently shut down the Kewaunee Power Station (KPS). On February 25, 2013, Dominion Energy Kewaunee (DEK) submitted a certification of permanent cessation of power operations pursuant to 10 CFR 50.82(a)(l)(i), stating that DEK has decided to permanently cease power operation of KPS on May 7, 2013. On May 15, 2013 the NRC docketed the certification for permanent removal of fuel from the reactor vessel pursuant to 10 CFR 50.82(a)(l)(ii). Therefore the 10 CFR Part 50 license no longer* authorizes KPS to operate the reactor or emplace or retain fuel in the reactor vessel, as specified in 10 CFR 50.82(a)(2). During 2015 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 Pathw;:iy-Organ Total Body Quarterly Limit (mRem) 7.5 Actual Dose (mRem) l.30E-04 (4th Quarter)

                                        % of Specification             1.73E-03 LIQUID:              Ingestion Pathway-Organ        Bone Quarterly Limit (mRem)         5.0 Actual Dose (rrtRem)           3.52E-03        (4th Quarter)

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, 2015. 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, major changes to the radioactive liquid and gaseous waste treatment systems, 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 evolutions at the Kewaunee Power Station. Page 3 of29

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 'concentrati6ns, dose rates and

            ,cumulative quarterly and annual doses. tqe ODCM methodology is acceptable for use
           *in demonstrating compliance with 10 CFR 20.i301/l302; 10 CFR 50, Appendix I; and 40CFR190.

2.0 GASEOUS EFFLUENTS 2.1 Lower Limits of Det~ction (LLD) for Gaseou~ Effluents Gaseous radioactive effluents are released in both the continuous mode and the batch mode. The auxiliary building stack is sampled continuou~ly for particulates, halogens and Strontium by l'.!-Il "off-line" sample traiU.

This stack is also gq1b-sampled weekly for gaseous gamma emitters and monthly for tritium. Batch releases are sampled prior fo release for principal gaseous and particulate gamma emitters, halogens and tritium.*

The LLD's for gaseous radio-analyses, as listed in Table 13.2J-1 of the Kewaunee ODCM are: Analysis LLD (µCi/ml) Gaseous Gamma Emitters 1.00E-04 Iodine 131 3;00E-12 Particulate Gamma Emitters 1.00E:.11 Particulate Gross Alpha l.OOE-11 Strontium 89, 90 l.OOE-'l l Noble Gases, Gross Beta or Gamma 1.00E~06 Tritium (H-3) l.OOE~06 The nominal "a priori" LLD values are shown below.

6. 7.1 The sample pump flow totalizer used for strontium sampling of the effluent from the auxiliary ventilation stack was found to be at zero flow on 5/31/2015. Sample flow volume was calculated manually using the start and stop time of the sample collection and then multiplying this vahie by the pump flow rate. The probable cause of the totalizer reading a zero value was loss of power due to electrical breaker cycling activities occurring five days earlier. CR5811l7.
