SUMMARY

During 2005 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:

GASEOUS: Ingestion Pathway-Organ Liver Quarterly Limit (mRems) 7.5 Actual Dose (mRems) 0.0002849 (4h Quarter)

% of Specification 0.003799 LIQUID: Ingestion Pathway-Organ GI-LLI Quarterly Limit (mRems) 5 Actual Dose (mRems) 0.007404 (2 nd Quarter)

% of Limit 0.15 SOLID: No upper limit for solid radioactive waste applies.

Cubic Meters Shipped 6.23 m3 (220 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, 2005. 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 ensure that offsite doses are maintained as low as reasonably achievable while still allowing for practical and dependable operation of the Kewaunee Power Station.

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 10CFR20.1302; 10CFR50, Appendix I; and 40CFRI90.

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 (gCi/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 l Strontium 89, 90 1.00 E-ll Noble Gases, Gross Beta or Gamma 1.00 E-06 The nominal "a priori" LLD values are shown below.

,, 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 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 2005 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 exceeded the concentrations specified in Appendix B. The following offsite doses were calculated using equation 1.7 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) was revised during this report period. A complete copy of Revision 9 of the ODCM is included as a part of this report.

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 8.1 Waste Gas Decay Tank Volume Calculation A Corrective Actions Program (CAP) evaluation, CAP030430, was submitted to identify and track the correction of this condition.

In December 2005 it was identified that the Waste Gas Decay Tank (WGDT) volume calculation used in the RETSCode computer program does not account for a Nitrogen purge of the tank, a practice which started in January 2001. The calculation in RETSCode uses the difference in tank gauge pressure with the pressure values in absolute pressure (gauge pressure + 14.7 psia). The calculation works if the release stops at zero or greater on the gauge. However, when the tank is at zero gauge pressure (atmospheric pressure of 14.7 psia) and it is subsequently purged, there is one volume of the tank that is discharged that is not taken into account. Therefore, the activity released from any purged WGDT is under reported.

A check of 5 WGDT release permits generated since 2001 and prior to implementation of immediate corrective actions for this issue showed initial pressures between 87 and 12 psig. The 12-psig-tank release volume is more than doubled (2.2 times the original volume) by the addition of volume needed to correct for the tank purge. The average release volume of these 5 releases is 40% more than the originally calculated volumes. Off-site dose has a linear correlation to volume released. The off-site doses from gaseous releases from the plant have been in the E-3 percentage ranges for the past 5-years as noted in the annual Radioactive Effluent Release Reports. Using the worst-case release volume noted above of 2.2 times greater than the original calculations results in a dose of no more than E-2 percentage of the quarterly limits, so there is no significant effect on reported doses to the public. No limits were approached.

Page 61 of 62

Regardless of the insignificant effect on the reported doses to the public, Dominion Energy Kewaunee will correct the previous data supplied for the affected time frame and submit the corrected information with the 2006 Annual Radiological Effluent Release Report.

8.2 Over Reporting of Beta-Emitting Isotope Activity for 2003 in Liquid Effluents An over reporting of beta-emitting isotopes was identified in the 2003 liquid effluents section of the Annual Radioactive Effluent Release Report. This over reporting was traced to manual entry of vendor supplied data. A Corrective Actions Program (CAP) evaluation, CAP029990, was submitted to identify and track the correction of this condition. A copy of this CAP is on file in the plant quality assurance vault. Appendix C of this report includes the entire report for liquid effluents for 2003 and represents the corrected data. Due to the multiple changes to monthly totals, quarterly total, total curies discharged and to doses, the entire liquid report was generated. In this case, the vendor supplied results for Fe-55, Sr-89, and Sr-90 were over-reported by a factor of two. The net result is a reduction in total discharges and reduction of dose to public.

Including this statement provides consistency between the ODCM and operating procedures ODCM Section 1.2.1 These changes were discussed previously for equation 1.2.

Equation 1.3 is equation 1.2 simplified for when CW = RR.

This equation was revised to allow use of nuclide specific sensitivities as in equation 1.2.

MPC was changed to IOXEC.

ODCM Section 1.2.2 The change from MPC's to EC's for limiting liquid effluent Changed the default from effective MPC value of IE-05 to concentrations is addressed in Appendix C. As shown in effective EC value of IE-06. Appendix C, the effective EC is a factor of 10 lower than the effective MPC. This approach essentially results in no change in limiting liquid effluents, since the revised limit is based on lOX the EC values.

This discussion found previously in appendix A previously used data from 1981-1983.

ODCM Appendix B Current data was used to verify that the current methodology Release information for noble gases was updated from1981- remained conservative. Previous data was from 1981 through 1983 to data from 2000-2002 Annual Effluent Reports. This 1983 information was used in evaluation of the noble gas dose factors.

ODCM Appendix C Administrative MPC changed to EC in Appendix C title.

ODCM Appendix The effective EC is a factor of 10 lower than the effective MPC.

Changed "MPC value of I OCFR2O, Appendix B, Table 11, This approach essentially results in no change in limiting liquid column 2" to 10 times the value of 10CFR20, Appendix B, effluents, since the revised limit is based on lOX the EC values.

ODCM Appendix C Update to Appendix C reflects use of EC values for the current EC values have been used in place of MPC to provide the 10 CFR 20, Appendix B, Table 2, Column 2. Use is consistent default effective EC value for determining the default monitor with current NRC guidance for limiting liquid effluent setpoints. concentrations and monitor setpoints.

ODCM Appendix C The current revision to the ODCM references the new 10 CFR References to Appendix B, Table 2, Column 2 have been 20.

Previous data used default values for the effective were still valid. This evaluation was from 1981. demonstrates that the default effective EC remains conservative.

ODCM Appendix C The justification for using EC values from the current 10 CFR Updated Table C- 1 using EC evaluation rather than MPC and 20, replacing the "old" MPC values has been discussed. More calculated using 2000-2002 data effluent reports. recent effluent data from 2000-2003 was used. EC values were calculated, to show that the default values for the effective were still valid as discussed in Appendix C.
