ZION NUCLEAR POWER STATION 2005 RADIOACTIVE EFFLUENT RELEASE REPORT UNIT 1 & 2 (DOCKET Numbers 50-295 & 50-304)

EXECUTIVE

SUMMARY

A review of 2005 effluent data indicates that the activity released from the station was far below any regulatory limit. There was no noble gas released in 2005. 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 2005 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 Releas;e Report.

A summary of changes made to the ODCM during 2005 and an entire copy of the ODCM, current as of December 31, 2005..

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 In Zion's defueled configuration this system is no longer applicable.

In Zion's defueled configuration, the charcoal iodine removal system is no longer applicable.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

AD200E5-9933 for 2RIA-PR49 and 2LP-084 (included with this report)

AD2005-0032 for 2RIA-PR49 and 2LP-084 (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 2005. 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 2005.

Zion Station Plan for the Return to Service of 2RIAPR49 and 2LP-084 Issue: Thirty Day Clock Expires on March 23, 2005 at 17:15 On February 21, 2005 at 17:15 2RIAPR49 and 2LP-084 was declared Out of Service (OOS). The issue being the isokenetic sampling system could not maintain the appropriate flow to the rad monitor. The series of events that lead to this OOS are the Glycol Heat Exchanger that provides heat for the incoming air sprung a leak and had to be taken OOS to facilitate repairs. Operations had to turn the supply fan off to prevent the Auxiliary Building from freezing and throttle back on the exhaust fans to balance the airflow in the Auxiliary Building.

This configunrtion places the effluent flow outside the operational band of the isokenetic sample panel.

The Glycol Hzat Exchanger had to be sent offsite to facilitate repairs. The removal of the heat exchanger and repairs has tak en several weeks to accomplish. The other issue to returning this equipment back to service is a set of rubber g askets (called a boot). Locating these boots will require additional time, 3 weeks from the time of this letter.

Zion Radiation Protection Procedure (ZRP) 5820-12 Revision 18 and ODCM Table 12.2-3 requires that: the 2RIA PR49 arid 2LP-084 must 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;.

The radiation monitor 2RIA-PR49 compensatory measures are:

Install a temporary blower and monitor the blower is operable once a shift

Record the flow on the appropriate attachment.

The flow panel 2LP-084 compensatory measures are

Estimate the flow once a day while the release is in progress.

The plan to return the rad monitor and sample panel back to service is;

Glycol Heat Exchanger to arrive onsite 4/18/2005

Boots arrive onsite 4/18/2005

Tech Rep to arrive onsite 4/19/2005

Reassembly and testing to occur April 20, 21, and 22

Return rad monitor and sample system to routine configuration 4/22/2005

Return 2RIAPR49 and 2LP-084 back to service 4/22/2005.

A-The station will require vendor assistance in the assembly of the heat exchanger. The goal of this plan is to insure that the fix for this heat exchanger prevents any leakage in that the contaminated glycol represents a "Mixed Waste" that is very expensive to rernediate.

Zion Station Plan for the Return to Service of 2LP-084 Issue: Thirty Day Clock Expires on November 2, 2005.

On October 3, 2C'05 2LP-084 was declared Out of Service (OOS) while performing the 18 month calibration.

The calibration includes flow response from channel 10 of 2RIA-PR49. Problems with the response of channel 10 prevented the completion of the calibration.

Zion Radiation Protection ODCM Table 12.2-3 requires 2LP-084 must 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.

This plan is the scheduled onsite support of a REP from Thermo Electron. He will assist with the repairs of channel 10 of 2R[A-PR49. The plan is for these repairs to allow for the completion of the calibration arid the return to service of 2LP084.
