SUMMARY

During 2008 all solid, liquid, and gaseous radioactive effluents from the Kewaunee Nuclear Plant were well below regulatory limits. For individual effluent streams, the quarterly limit most closely approached was:

GASEOUS: Ingestion Pathway-Organ Liver Quarterly Limit (mRems) 7.5 Actual Dose (mRems) 3.559E-4 ( 2 nd Quarter)

% of Specification 0.004745 LIQUID: Ingestion Pathway-Organ Total Body Quarterly Limit (mRems) 1.5 Actual Dose (mRems) 5.408E-4 (1st Quarter)

%of Limit 0.03606 SOLID: No upper limit for solid radioactive waste applies.

Cubic Meters Shipped 86.24 m3

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 3/4.7. It includes data from all effluent releases made from January 1 - December 31, 2008. 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 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.

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.

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.

I 2.0 GASEOUS EFFLUENTS I 2.1 Lower Limits of Detection (LLD) for Gaseous Effluents I 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 daily for gaseous gamma emitters. Batch releases I

are sampled prior to release for principal gaseous and particulate gamma emitters, halogens and tritium.

I The LLD's for gaseous radioanalyses, as listed in Table 4.4 of the Kewaunee ODCM are:

Analysis LLD ([tCi/ml) i Gaseous Gamma Emitters Iodine 131 1.00 3.00 E-04 E-12 I

Particulate Gamma Emitters 1.00 E-1I Particulate Gross Alpha Strontium 89, 90 1.00 1.00 E-11 E-1I I

Noble Gases, Gross Beta or Gamma 1.00 E-06 I

The nominal "a priori" LLD values are shown below.

I 2.2 Gaseous Batch Release Statistics U The following is a summation of all gaseous batch releases made during 2008.

Number of batch releases ....................... 53 I

Total time for all batch releases (min) ............ 26,120.0  !

Maximum time for a batch release (min) ............. 2,305.0 I

Average time for a batch release (min) ............. 492.8 Minimum time for a batch release (min) ............. 7.0 i 2.3 Gaseous Effluent Data I

The following table 2.1 presents a quarterly summation of the total activity released and average release rates of four categories of gaseous effluents. 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 3.0 LIQUID EFFLUENTS 3 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 i 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 and Iron 55.

I Instantaneous release concentrations are limited by the individual radionuclide concentrations I 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 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 Offsite Dose Calculation Manual The Offsite Dose Calculation Manual (ODCM) has not been revised during this report period.

7.2 Major Changes to the Radioactive Liquid, Gaseous and Solid Waste Treatment Systems Major changes to the radioactive liquid, gaseous or solid waste systems are submitted in the annual Updated Final Safety Analysis Report consistent with Technical Specification 6.19.

8.0 REPORTABLE OCCURRENCES No reportable occurrences in 2008.

The Event Notification Worksheet 2006 is being included because all the ground water results prior to 2008 are included in this report.

At 1400 on 8/10/06 KPS is planning on making a notification to the State and Local Government that samples taken at settling plugs in the basement of the Auxiliary Building and Turbine Building show elevated tritium levels. Detected tritium levels were between 6,000 and 103,000 pico curries per liter. The Radiological Effluent Program has not detected any elevated tritium levels outside the plant.

RCS leakage is .19 gpm, stable and within Technical Specification limits and there is currently no identified leakage from the Spent Fuel Pool.

Investigation is continuing to identify the reason for the increase in tritium levels.
