SUMMARY

3 During 2010 all solid, liquid, and gaseous radioactive effluents from the Kewaunee Power Station were well below regulatory limits. For individfial effluent-streams, the quarterly limit most closely approached was:

.GASEOIIS:

Ingestion Pathway-Organ Liver Quarterly!Limit (mRems) 7.5

Actual Dose (mRems) 0.00017.3, (4 Quarter)

% of Specification 0.002306 LIQUID:

Ingestion Pathway-Organ Total Body Quarterly Limit (mRems) 1.5 Actual Dose (mRems) 0.0004926 (4d' Quarter)

% of Limit 0.03284 3

SOLID:

No upper limit for solid radioactive waste applies.

Cubid Meters Shipped 41-.26 m 3 (1460 ft3).

1.0 INTRODUCTION

This report is being submitted in accordance with the requirements of Kewaunee Technical Specifications, Section 6.9.b.2 and the Offsite Dose Calculation Manual, Section 3/4.6. It includes data from all effluent releases made from January' 1 -,December 31, 2010. 'The report contains.,

I summaries of the gaseous and liquid releases made to the environment including the quantity, characterization, time duration and calculated radiation dose. ft the site, boundary resulting from these releases. The report also includes a summation of solid 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 (LLD) values is identified in sections 2.1 and 3.1..

1.1 Effluent Dose Limits Specifications are set to insure that offsite doses are maintained as low as reasonably achievable while still allowing for practical and dependable operation of the Kewaunee Plant.

" 1 7.1.

1 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 setpoints.

3 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 20.106; 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 effluents are released in both the continuous mode and the batch mode. The auxiliary building stack is sampled continuously, 4Qr~particulates, iodine, noble gases and Strontium by an "off-line" sample train. This stack is also grab-sampled daily for gaseous gamma emitters. Batch releases are sampled prior to release for principal gaseous and particulate gamma emitters, iodine, noble gases and tritium.

The LLD's for gaseous radioanalyses, as listedin Table 4-,4, of the Kewaunee ODCM are:

Analysis LLD (qCi/ml)

Gaseous Gamma Emitters Iodine 131 Particulate Gamma Emitters Particulate Gross Alpha Strontium 89, 90 Noble Gases, Gross Beta or Gamma 1.00 E-04 3.00E-12 1.00 E-11 1.00 E-IlI 1.00 E-11 1.00 E-06 The nominal "a priori" LLD values are shown below.

2.2 Gaseous Batch Release Statistics The following is a summation of all gaseous batch releases made during 2010.

Number of batch releases....................................

Table 2.2 lists the quarterly sums of individual gaseous radionuclides released by continuous and batch modes. Table' 2.3 is essentially the same data, but is presented as monthly summations. Table 2.4 presents the dose limits for gaseous effluents, and the calculated doses this year from gaseous effluents.

I 2.4 Estimation. of arbon,14 in Gaseous Releases (Calculation C11988 Rev. 0)

Kewaunee Power Station conducted a site specific analysis to determine the amount of C-14 generated, the percentage that is ina form contributing to offsite doses, and-the impaci tothe public. C-14 isnot a new emission; because of improyements in power plant operatioiis C-14 now: qualifies as a principle radionuclide under Federal regulations. Unlike other principle radionuclides, the contribution of C-14 is calculated, not measured. The calculation iricIiides conservative assumptionsto estimate:I'the dose.

The total estimatet C-1'4 released'was 6.133 Ci.

30% of the estimated C-14 releasedwas assumed to be in the form of CO 2.

The highest estimated C-14 doses were at the highest X/Q for ingestion and inhalation receptor (6ne mile west).

3.0 LIOUID 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 fractioh of each sample is'-

retained for a monthly proportional composite which is then analyzed for Gross Alpha; Strontium: 89, Strontium 90 and Iron 55.

Table 3.4 : ý I Annual Radioactive Effluent Report 2010 Dose.From Liquid Effluents The dose to a member of the public from total liquid radioactive releases for each quarter was below the ODCM limits of 1.5 mrems to the total body and less than or equal to 5 mrems to any organ.

Additionally, the dose to a member of the public from total liquid radioactive releases for the year was below the ODCM limits of 3 mrems to the total body and less than or equal to 10 mrems to any organ.

Instantaneous release concentrations are limited by the individual radionuclide concentrations 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 1.5 from the Kewaunee ODCM.

7.0 PROGRAM REVISIONS In accordance with Kewaunee Technical Specifications 6.18.b.3 and 6.19.a, the revisions to the Process Control Program, Offsite Dose Calculation Manual and radioactive waste treatment systems are listed below.

7.1 Process Control Program Two minor revisions were made to the Process Control Program (PCP) during 2010. Revision 9 removed two commitment items that were not NRC commitments, changed the name of the committee to review changes to the PCP from Plant Operations Review Committee (PORC) to Facility Safety Review Committee (FSRC). Revision 10 added procedure references to support the implementation of the Improved Technical Specifications (ITS) and CurrentTechnical Specifications (CTS).

7.2 Offsite Dose Calculation Manual The Offsite Dose Calculation Manual (ODCM) has not been revised during this report period.

7.3 Major Changes to the Radioactive Liquid, Gaseous and Solid Waste Treatment Systems There were no changes to the radioactive waste systems (liquid, gaseous or solids) during this report period.

8.0 REPORTABLE OCCURRENCES None.
