ZION NUCLEAR POWER STATION 2006 RADIOACTIVE EFFLUENT RELEASE REPORT UNIT 1 & 2 (DOCKET Numbers 50-295 & 50-304)

EXECUTIVE

SUMMARY

A review of 2006 effluent data indicates that the activity released from the station was far below any regulatory limit. There was no noble gas released in 2006. 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 2006 UNIT I & 2 (Docket Numbers 50-295 & 50-304)

ADDENDUM I.

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 2006 and an entire copy of the ODCM, current as of December 31, 2006.

2.

Gaseous and Liquid Waste 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 Annual 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 In Zion's defueled configuration this system is no longer applicable.

In Zion's defueled configuration, the charcoal iodine removal system is no longer applicable.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

AD2006-0011 for 2RIA-PR49 (included with this 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 2006. 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 2006.

Gaseous Effluents Sampling Error 5%

Calibration Error 10%

Counting Statistics Error 17%

Sample Volume Error 10%

Total Error 23%

Letter to File Date; February 7, 2006

Subject:

Zion Station 30 Day Return to Service Letter for 2RIA-PR49 Channel 7 On Jan 9, 2006 2RIA-PR49 was declared out of service while performing the 18 month calibration. Instrument Maintenance personnel were unable to complete the calibration of channel 7.

Zion Radiation Protection ODCM table 12.2-3 requires channel 7 to be returned to service within 30 days. If the monitor is not returned to service within 30 days the station is to conduct a station review to determine the plan to return the monitor to an operable status.

Channel 7 is a noble gas monitor designed to detect noble gas releases associated with a severe accident conditions. There are no longer any severe accident scenarios postulated for Zion Station while in the permanently defueled condition. Therefore channel 7 is no longer required. A permanent change to chapter 12 of the ODCM has been approved.

This change eliminates the requirement to maintain 2RIA-PR49 channel 7.

Implementation of the change is in progress.
