July 2, 2014 MEMORANDUM TO: Biweekly Notice Coordinator FROM: Bruce Watson, Chief /RA/
Reactor Decommissioning Branch Decommissioning and Uranium Recovery Licensing Directorate Division of Waste Management and Environmental Protection Office of Federal and State Materials and Environmental Management Programs
SUBJECT:
REQUEST FOR PUBLICATION IN BIWEEKLY FEDERAL REGISTER NOTICE - NOTICE OF CONSIDERATION OF ISSUANCE OF AMENDMENT TO FACILITY OPERATING LICENSE, PROPOSED NO SIGNIFICANT HAZARDS CONSIDERATION DETERMINATION, AND OPPORTUNITY FOR A HEARING ZionSolutions LLC (ZS), Docket Nos. 50-295 and 50-304, Zion Nuclear Power Station (ZNPS),
Units 1 and 2, Lake County, Illinois Date of amendment request: May 27, 2014 Description of amendment request: The license amendment request proposes changes to ZNPS Defueled Station Emergency Plan (DSEP) in accordance with 10 CFR 50.54(q).
ZS proposes removal of the various emergency actions related to the former spent fuel pool, the transfer of responsibility for implementing the Emergency Plan to the Independent Spent Fuel Storage Installation (ISFSI) Shift Supervisor, a revised emergency plan organization, abandonment of the Control Room consistent with the current state of decommissioning, transition to NEI 99-01 Revision 6 and reformatting consistent with current industry practice.
Basis for proposed no significant hazards consideration determination: As required by 10 CFR 50.91(a), the licensee has provided its analysis of the issue of no significant hazards consideration, which is presented below:
2 (1) Does the change involve a significant increase in the probability or consequences of an accident previously evaluated?
No. ZS has, in effect, a U.S. Nuclear Regulatory Commission-approved (NRC) emergency plan. The remaining ZNPS accident (Radioactive Waste Handling Accident) and the credible accidents involving the ISFSI and the Modular, Advanced Generation, Nuclear All-purpose Storage (MAGNASTOR) system have been analyzed and determined that none result in doses to the public beyond the owner controlled area boundary that would exceed the U.S. Environmental Protection Agencys (EPA)
Protective Action Guides (PAGs). These analyses have not changed. With spent fuel relocated to the ISFSI, the Spent Fuel Pool previously analyzed events (Loss of Spent Fuel Pool Cooling, Loss of Spent Fuel Pool Inventory, and Fuel Handling Accident in the Fuel Building) are no longer credible.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
(2) Does the change create the possibility of a new or different kind of accident from any accident previously evaluated?
No. ZS has, in effect, an NRC-approved emergency plan. The remaining ZNPS accident (Radioactive Waste Handling Accident) and the credible accidents involving the ISFSI and MAGNASTOR system have been analyzed and determined that none result in doses to the public beyond the owner controlled area boundary that would exceed the EPAs PAGs. These analyses have not changed. With spent fuel relocated to the ISFSI, the Spent Fuel Pool previously analyzed events (Loss of Spent Fuel Pool Cooling, Loss of Spent Fuel Pool Inventory, and Fuel Handling Accident in the Fuel Building) are no longer credible. Accidents associated with the ISFSI are addressed in the MAGNASTOR Final Safety Analysis Report.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
(3) Does the change involve a significant reduction in a margin of safety?
No. Margin of safety is related to the ability of the fission product barriers (fuel cladding, reactor coolant system, and primary containment) to perform their design functions during and following postulated accidents. ZS has, in effect, an NRC-approved emergency plan. The remaining ZNPS accident (Radioactive Waste Handling Accident) and the credible accidents involving the ISFSI and MAGNASTOR system have been analyzed and determined that none result in doses to the public beyond the owner controlled area boundary that would exceed the EPAs PAGs These analyses have not changed. With spent fuel relocated to the ISFSI, the Spent Fuel Pool previously analyzed events (Loss of Spent Fuel Pool Cooling, Loss of Spent Fuel Pool Inventory, and Fuel Handling Accident in the Fuel Building) are no longer credible.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
3 The NRC staff has reviewed the licensee's analysis and, based on this review, it appears that the three standards of 10 CFR 50.92(c) are satisfied. Therefore, the NRC staff proposes to determine that the amendment request involves no significant hazards consideration.
