SUMMARY

This Annual Radioactive Effluent Release Report (Report # 29) documents the quantities of liquid and gaseous effluents and solid waste released by Wolf Creek Generating Station (WCGS) from January 1, 2005 through December 31, 2005. The format and content of this report are in accordance with Regulatory Guide 1.21, Revision 1, "Measuring, Evaluation, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants." Sections 1,11, III, and IV of this report provide information required by NRC Regulatory Guide 1.21 and Section 7.2 of AP 0713-003, "Offsite Dose Calculation Manual" (ODCM).

Section I--- Section I contains, in detail, the quantities of radioactive liquid and gaseous effluents and cumulative dose summaries for 2005, tabulated for each quarter and for yearly totals.

Specific ODCM effluent limits and dose limits are also listed in Section I, along with the percentage of the effluent limits actually released and the percentages of the dose limit actually received. No effluent or dose limits were exceeded during 2005.

An elevated release pathway does not exist at WCGS. All airborne releases are considered to be ground level releases. The gaseous pathway dose determination is met by the WCGSC)DCM methodology of assigning all gaseous pathways to a hypothetical individual residing at the' highest annual X/Q and D/Q location, as specified in the ODCM. This results in a conservative  ?)

estimate of dose to a member of the public, rather than determining each pathway dose for. each release condition. A conservative error of thirty percent has been estimated in the effluent~data. l K As stated above;,no ODCM dose limits were exceeded in 2005.

Section 11:--- Section II includes supplemental information on continuous and batch releases,.>-

calculated doses, and solid waste disposal. There were 72 gaseous batch releases in 2005 versus 67 in 2004. There were 62 liquid batch releases in 2005 versus 58 in 2004. \WICGS released 0.014 curies in liquid releases during 2005 versus 0.019 curies in 2004, excluding gas and tritium. Continuous release pathways remained the same as previous years and all continuous releases were monitored.

The report contains information on the following Performance Improvement Request (PIR):

PIR 2005-1836 - While performing a Volume Control Tank (VCT) purge to Gas Decay Tank #3 (GDT), a leak was identified on a moisture separator pressure switch (HAPS1035B). The leak resulted in an unplanned, monitored release.

Section III --- Section III documents WCGS meteorological data for wind speed, wind direction, and atmospheric stability.

Section IV --- Section IV documents unplanned and abnormal releases, changes to radwaste treatment systems, land use census, monitoring instruments, radwaste shipments, and storage tank quantities. There was one unplanned, monitored release in 2005.

No changes to events occurred on the land use census, monitoring instruments, radwaste shipments, and storage units.

1) Thce percent of ODCM limit for fission and activation gases iscalculated using the following methodology:

(Qtrly Total Beta Airdose)(100) (Qtrly Total Gamma Airdose)(100)

% of ODCM Limit = or 10 mrad 5 mrad The largest value calculated between Gamma and Beta air dose islisted as the % of ODCM Limit.

2) The percent of ODCM limit for iodine is calculated using the following methodology:

% ofODCMLimit (Total Curies of Iodine-131)(100)

I Curie

3) The percent of ODCM limit for particulates iscalculated using the following methodology:

% of ODCM Limit = (Highest Organ Dose Due to Particulates)(100) 7.5 mrem This type of methodologyis used since the Wolf Creek ties release limits to doses rather than curie release rates.

5. Balch Releases A batch release is the discontinuous release of gaseous or liquid effluents which takes place over a finite period of time; usually hours or days.

There were 72 gaseous batch releases during the reporting period. The longest gaseous batch release lasted 9777 minutes, while the shortest lasted 75 minutes. The average release lasted 538 minutes with a total gaseous batch release time of 45,683 minutes.

There were 62 liquid batch releases during the reporting period. The longest liquid batch release lasted 375 minutes, while the shortest lasted 30 minutes. The average release lasted 156 minutes with a total liquid batch release time of 10,545 minutes.

6. Continuous Releases A continuous release is a release of gaseous or liquid effluent, which is essentially uninterrupted for extended periods during normal operation of the facility. Four liquid release pathways were designated as continuous releases during this reporting period:

Steam Generator Blowdown, Turbine Building Sump, Waste Water Treatment, and Lime Sludge Pond. Two gas release pathways were designated as continuous releases: Unit Vent and Radwaste Building Vent.

7. Doses to a Member of the Public from Activities Inside the Site Boundary Four activities by members of the public were considered in this evaluation: personnel making deliveries to the plant, workers at the William Allen White Building located outside of the protected area boundary, the use of the access road south of the Radwaste Building, and public use of the cooling lake during times when fishing was allowed. The dose calculated for the maximum exposed individual for these four activities vwas as follows:

Plant Deliveries 3.36E-01 mRem William Allen White Building Workers 7.42E-03 mRem Access Road Users 3.54E-03 mRem Lake Use 4.57E-02 mRem The plant delivery calculations were based on deliveries 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> per week for 50 Weeks per year. The William Allen White Building occupancy was based on normal working hours of 2000 per year. The usage factor for the access road south of the Rac'waste Building was 25 hours2.893519e-4 days <br />0.00694 hours <br />4.133598e-5 weeks <br />9.5125e-6 months <br /> per year.

8. Additional Information PIR 2005-1836 - While performing a Volume Control Tank (VCT) purge to Gas Decay Tank #3 (GDT), a leak was identified on a Swagelok fitting on a moisture separator pressure switch (HAPS1035B). During the VCT purge, the Radwaste Treatment Systems Operator noticed a significant drop in pressure. The purge was secured and the system lineup verified, with no deficiencies found. The leak was found to be at a fitting on HAPS1035B, which allowed an unexpected pressure loss from GDT #3, from 21 psig to 6.8 psig over a time period of 94 minutes. Work Request 05-050478 was written. The leak resulted in an unplanned, monitored release of noble gases from the Radwaste Building Vent. No ODCM limits were exceeded. An estimated 6.22E-03 curies were released.
