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 CPR 50.82(a)(l)(i), stating that DEK has decided to permanently cease power operation ofKPS 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 CPR 50.82(a)(l)(ii). Therefore the 10 CPR Part 50 license no longer authorizes KPS to operate the reactor or emplace or retain fuel in the reactor vessel, as specified in 10 CPR 50.82(a)(2).

On June 15, 2017, the transfer of all spent fuel from the KPS Spent Fuel Pool (SFP) to the Independent Spent Fuel Storage Installation (ISFSI) was completed. All remaining irradiated materials were removed from the SFP in October 2017.

During 2017 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:

1.0 INTRODUCTION

This report is being submitted in accordance with the requirements bf Kewaunee Technical Requirements Manual, Section 10.3.2 andthe,Offsite-Dose Calculation Manual; Sectioil'15:2, It ;

includes data from all effluent releases*made from January 1.:.December 31, 2017; The report contains summatj.es of the gaseous and liquid releases made to the environment-including the quantity, characterization:, time quration and calculated radiation dose at the site boundary resulting from* these releases;,The report also irtclu,des a summation*ofsolid radioactive. waste disposal, revision~;' to the" Process c;,_:mtrol J:>rogr~ arid the Offsite Dose Calculation Manual; majorchanges*to the radioactive

  • liquid and gaseous waste treatment systems, and addresses the cumulative meteorological data. Values indicated as O (zero) in this report refer to actual values less than the detection limits. A table of these less than detectable (LLD) values is identified fa sections 2.1 and 3.1.

1.1 Effluent Dose Limits Specifications are set to ensure that offsite,doses are maintained as low as reas'onably;achievable while still allowing for practical and depend~ple evolutions at the Kewaunee Power Station.;,* !. * *, :; ;,. ;

,),.' _,,.

The Kewaunee Offsite Dose Calculation.Manual (ODCM) describes the methodology and parameters used in:

1.)

The calculation ofradioactiveJiquid and gaseous effluent monitoring instrumentation alarm/trip set points.

2.)

The calculation of radioactive liquid and*gase.ous concentrations; *dose rates and cumulative quarterly and annual doses. The ODCM methodology is acceptable for use in demonstrating compliance with 10 CFR*20.I301/1302;.10 CFR 50, Appendix I; and 40 CFR 190.

2.0 GASEOUS EFFLUENTS 2.1 Lower Limits of Detection (LLD) for Gaseous Effluents Gaseous radioactive effl,.uents 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 and monthly**

for tritium. Batch releases :are s~pled prior to release for principal gaseous and particulate gamma emitters, halogens.and tritium*.

. :, Tal,le 3.fl, Dose from Liquid Effluents' The dose to a member of the public from total liquid radioactive releases for each quarter was below the Kewaunee OD<;M limits of 1 ;5 *mrem to the total )Jody and less than or equal tQ 5 mrem,;to any organ. Additionally, the qose to a member of the public from total liq1,lid radioactive releases fo~ the year was below the Kewaunee ODCM limits of 3 mrem to the total body and less than or equal to 10 mrem to any organ.

Instantaneous release concentra_ti9ns are :limited bytfo.:i,individual radionuclide concentratjon~

established in 10 CFR 20, Appendix B, for unrestricted areas. During the report period, none of the isotopes released exceed the concentrations specified in Appendix B. The following offsite doses were calculated using equation 1.7 froi:µ the K,ewaunee.,ODCM.

' * : ' l..

Due to the Ni-63 activity levels and the volume of water released to the environment in 2017 the dose due to liquid effluent releases exceeded 1 % for both the quarterly and annual limits for multiple organs.

The highest quarterly percentage was 28.4% and highest annual percentage was 20%. Neither of the dose limits was at risk of being exceeded based on close monitoring of dose projections, use of the radioactive waste treatment system, and procedural guidance. There was no adverse impact to the general public.

KPS Did Not Meet Annual Availability of90% for Meteorological Data in 2017.

Procedure RP-KW-001-025, Meteorological Monitoring, has an annua(dat~a\\railability goal of 90% *a~

required by Regulatory Guide 1.23 for operating nucleai: power plants. Kewaunee Power Station achieved 85%, avaiiability in 2017. The lo~er rate of a.J~ilabillty*was not due to instrtiment problems but due to loss ofR-Time data archiving in the 2nd and 4th quarters of 2017. The data is not retrievable' for these periods. The 90% availability goal is primarily associated with dose projection calculations for Emergency Planning. Going forward meteorological data monitoring and archiving will no longer be required at Kewaunee Power Station. Evaluations involving meteorological d.ita sucli' as'ef:fluent * *'

dispersion det~rminations wj,11 be based on historicaJ data summaries rather than current meteorological data. ~~f<)Y.~9?;1,-P~~ ~il.1._~e-deleted. ". ', '..
