Attachment 1: Radioactive Effluent Release Report Attachment 1: ZION NUCLEAR POWER STATION 2011 RADIOACTIVE EFFLUENT RELEASE REPORT UNIT 1 & 2 (DOCKET Numbers 50-295 & 50-304)EXECUTIVE

SUMMARY

A review of 2011 effluent data indicates that the activity released from the station was far below any regulatory limit. There was no noble gas released in 2011. This trend can be attributed to the shutdown of both units since late September 1997.Airborne Dose to Maximally Exposed Receptor from Unit 1 Dose to Maximally Exposed Receptor from Unit 2 Gamma Air 0 mrad 0 mrad Beta Air 0 mrad 0 mrad Total Body 2.26E-04 mrem 6.00E-5 mrem (Adult) (Child)Skin 0 mrem 0 mrem Organ 6.32E-04 mrem 6.00E-05 mrem (Infant Liver) (Child Liver)There was NO Aquatic release of radioactivity from Zion Station for 2011.Aquatic Dose to Maximally Exposed Receptor (Any)from Unit 1 Dose to Maximally Exposed Receptor (Any)from Unit 2 Total Body 0 mrem 1 0 mrem Organ 0 mrem 0 mrem K:\RP\EFFLUENT\1OAER\AER201 lexec sum ZION STATION 2011 Unit 1 10CFR20 Compliance Assessment

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 2011 and an entire copy of the ODCM, current as of December 31, 2011, and required to be submitted.

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 In Zion's defueled configuration this system is no longer applicable.

In Zion's defueled configuration, the charcoal iodine removal system is no longer applicable.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

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.The contents of the six gas decay tanks have been sampled and determined to have negligible activity.

The Gas Decay Tanks have been abandoned in place.No liquid holdup tanks exceeded the limits of Permanently Defueled Technical Specifications
