Subject:

Radioaet-ive Effluent Release Report for 2009 and Offsite Dose Calculation Manual for 2009 ..

In accordance with 10 CFR 50.36a, "Technical specifications on effluents from nuclear power plants," and pursuant to Technical Specification 5.7.3, "Radioactive Effluent Release Report,"

for Zion Nuclear Station, Units 1 and 2, this is the submittal of a Radioactive Effluent Release Report for the year 2009. The report is required to be submitted by April 30, 2010 and is provided as 1st Attachment to this letter. A listing of commitments contained in this submittal is provided as 2nd Attachment.

Pursuant to 10 CFR 50.4, there were no changes made to the Exelon Nuclear Offsite Dose Calculation Manual (ODCM) during the period of January through December 2009.

Technical Specification 5.6.1 for the Zion Nuclear power station requires a copy.of the entire ODCM be submitted to the NRC as part of, or concurrent with, the Radioactive Effluent Release Report. This must be submitted prior to May 1. A copy of the entire Exelon ODCM, current as of December 31, 2009 is provided as an Attachment.

If you have any questions about this submittal please contact Mr. Ken Greenlee at 847-379-2700.

ZION NUCLEAR POWER STATION 2009 RADIOACTIVE EFFLUENT RELEASE REPORT

" UNIT I & 2 (DOCKET Numbers 50-295 & 50M304)

EXECUTIVE

SUMMARY

A review of 2009 effluent data indicates that the activity released from the station was far below any regulatory limit. There was no noble gas released in 2009. This trend can be attributed to the shutdown of both units since late September 1997.

ZION NUCLEAR POWER STATION ANNUAL RADIOACTIVE EFFLUENT RELEASE REPORT FOR 2009 UNIT I & 2 (Docket Numbers 50-295 & 50-304)

ADDENDUM 1'. Offsite Dose Calculation Manual (ODCM)

Changes to the ODCM are required by Zion Station Permanently Defueled Technical Specification 5.6.1. and ODCM Section 12.6.3 to be submitted as part of, or concurrent with, the Annual Radioactive Effluent Release Report.

A summary of changes made to the ODCM during 2009 and an entire copy of the ODCM, current as of December 31,2009.

2. Gaseous and Liquid Wasie Treatment Systems and Process Control Program Zion Station ODCM Section 12.6.4 requires major changes to the Gaseous and Liquid Waste Treatment Systems to be reported in the Anmual Radioactive Effluent Release Report.

The Waste Gas Hold-up System was permanently vented. In Zion's defueled configuration this system is no longer applicable.

In Zion's defueled configuration, the charcoal iodine removal system is no longer applicable.

Due to radioactive decay and no means of production, radioactive iodine is not a concern at Zion.

3. Limiting Conditions of Operation (LCOs)

Zion Station ODCM Section 12.7.2 requires explanation as to why the inoperability of liquid or gaseous monitoring instrumentation was not corrected within the time specified in the ODCM to be submitted with the Annual Radioactive Effluent Release Report.

4. Liquid Holdup Tanks and Gas Storage Tanks Zion Station ODCM Section 12.7.2 requires a description of events leading to liquid holdup tanks or gas storage tanks exceeding technical specification limits to be included in the Annual Radioactive Effluent Release Report.

There was no activity present in any gas decay tanks during 2009. The Gas Decay Tanks have been abandoned in place.

No liquid holdup tanks exceeded the limits of Permanently Defueled Technical Specifications 5.6.3 during 2009.
