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.Page 3 of 63

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 ([tCi/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 3.00 E-12 1.00 E-1I 1.00 E-11 1.00 E-1I 1.00 E-06 I I I I I i I I I 3 I i i I I I I The nominal "a priori" LLD values are shown below.Isotope a priori LLD (jiCi/ml)a.

2.3 Gaseous

Effluent Data 7.0 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.

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./~VI Ufce.4&' 1L4_-J4a..'ý6 Cix.'ry,,r~,h T' !, 709ý.fto AV4k 461azot /.)eO/ Zit:-a')AT 10c~ C .7- c-4 %J z)-: -AA 4 I-01-l -It if),)W -* -C c -)ý,J -',,AJ 91--_61C-1,44-61ýý7Jc'E NOTIFICATIONS YES NO WILL BE ANYTHING UNUSUAL OR -YES (Explainabove)
