SUMMARY

During 2002 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) 0.00002016 (2nd Quarter)

% of Specification 0.0002689 LIQUID: Ingestion Pathway-Organ GI-LLI Quarterly Limit (mRems) 5 Actual Dose (mRems) 0.008593 (1s'Quarter)

% of Limit 0.17 SOLID: No upper limit for solid radioactive waste applies.

Cubic Meters Shipped 18.4 m3 (650 fl3)

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, 2002. 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.

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 l; 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 for particulates, halogens 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, halogens and tritium.

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

Analysis LLD (ipCi/ml)

Gaseous Gamma Emitters 1.00 E-04 Iodine 131 3.00 E-12 Particulate Gamma Emitters 1.00 E-l 1 Particulate Gross Alpha 1.00 E-l 1 Strontium 89, 90 1.00 E-l l Noble Gases, Gross Beta or Gamma 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 2002.

Number of batch releases ........................... 34 Total time for all batch releases (min)............ 11264.0 Maximum time for a batch release (min)............. 1219.0 Average time for a batch release (min)............. 331.3 Minimum time for a batch release (min)............. 8.0 2.3 Gaseous Effluent Data and average The following table 2.1 presents a quarterly summation of the total activity released quarterly sums of individual release rates of four categories of gaseous effluents. Table 2.2 lists the the same data, gaseous radionuclides released by continuous and batch modes. Table 2.3 is essentially gaseous effluents, and but is presented as monthly summations. Table 2.4 presents the dose limits for the calculated doses this year from gaseous effluents.

3.0 LIQUID 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 and Iron 55.

Table 3.4 Annual Radioactive Effluent Report 2002 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 ofthe isotopes released exceed the concentrations specified in Appendix B. The following offsite doses were calculated using equation 1.5 from the Kewaunee ODCM.

4.0 UNPLANNED RELEASES No unplanned releases were made from the Kewaunee Plant during the report period.

The January-June 1991 Semi-Annual Effluent Release Report described an unplanned release which occurred on April 25, 1991. Offsite doses attributed to this release were well below the established ODCM (Technical Specifications at the time) limits.

As corrective action, WPSC stated in this report that valves WG-301 and WG-302 were scheduled to be replaced during 1992. Also, a new vent line was added between valves WG-300 and WG-301 to allow local leak rate testing with the Waste Gas Decay Tanks isolated. The valves were to be replaced with like-for-like replacements. However, after receipt inspection, the replacement valves failed to pass the seat leakage tests. WPSC is continuing to evaluate options associated with these valves and will continue to provide status updates in the Effluent Release Reports until resolution of this incident and completion of the corrective actions. A plant design change request, DCR-2349, was issued to address this concern.

5.0 METEOROLOGICAL DATA Meteorological data for 2002 is retained on file at the Kewaunee Nuclear Power Plant. The data on file includes a continuous strip chart recording and a 15-minute interval listing of wind speed, wind direction and atmospheric stability. This is more conservative than the requirements of ODCM Section 3/4.7. See Appendix A for missing meteorological data and the joint frequency distribution tables.

6.0 SOLID WASTE DISPOSAL Table 6.1 is a summation of solid wastes shipped during 2002. Presented are the types of wastes, major nuclide composition, disposition of the wastes and shipping containers used.

The containers utilized at Kewaunee Nuclear Power Plant have the following volumes:

High Integrity Container (HIC) 158 ft3 LSA Box (B-25) 98 ft3 Compactor Boxes 50 ft3 DOT-17H Drum 7.5 ft3 A composite sample from the 1993 dewatered resin shipments was analyzed by a contractor for transuranic nuclides. The results showed an average transuranic concentration of 4.24 E-2 nanocuries/gram, well within the disposal site limit of 10 nanocuries/gram.

Table 6.1 contains the radionuclide content (curies) and percent abundance for each type of waste.
