January 22, 2007 MEMORANDUM TO: Biweekly Notice Coordinator FROM:
John B. Hickman, Project Manager /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 (TAC NO. J52668)
Sacramento Municipal Utility District, Docket No. 50-312, Rancho Seco Nuclear Generating Station, Sacramento County, California Date of amendment request: April 12, 2006, and supplemented November 21, 2006 Description of amendment request: The licensee has proposed to amend its license to incorporate a new license condition addressing the license termination plan (LTP). This amendment will document the approval of the LTP, document the criteria for making changes to the LTP which will and will not require pre-approval by the NRC, and will document any conditions imposed with the approval of the LTP.
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:
1.
Does the proposed license amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Biweekly Notice Coordinator No. The proposed change is administrative. The change allows for the approval of the LTP and provides the criteria for when changes to the LTP require prior U.S.
Nuclear Regulatory Commission (NRC) approval. This change does not affect possible initiating events for accidents previously evaluated or alter the configuration or operation of the facility. Safety limits, limiting safety system settings, and limiting control systems are no longer applicable to Rancho Seco in the permanently defueled mode, and are therefore not relevant.
The proposed change does not affect the boundaries used to evaluate compliance with liquid or gaseous effluent limits, and has no impact on plant operations.
Therefore, the proposed license amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated.
2.
Does the proposed license amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
No. As described above, the proposed change is administrative and provides the criteria for when changes to the LTP require prior NRC approval. The safety analysis for the facility remains complete and accurate. There are no physical changes to the facility as a result of the proposed amendment and the plant conditions for which the design basis accidents have been evaluated are still valid.
The operating procedures and emergency procedures are not affected. The proposed changes do not affect the emergency planning zone, the boundaries used to evaluate compliance with liquid or gaseous effluent limits, and have no impact on plant operations. Consequently, no new failure modes are introduced as the result of the proposed changes. Therefore, the proposed changes will not create the possibility of a new or different kind of accident from any accident previously evaluated.
3.
Does the proposed license amendment involve a significant reduction in a margin of safety?
No. As described above, the proposed changes are administrative. There are no changes to the design or operation of the facility. The proposed changes do not affect the emergency planning zone, the boundaries used to evaluate compliance with liquid or gaseous effluent limits, and have no impact on plant operations.
Accordingly, neither the design basis nor the accident assumptions in the Defueled Safety Analysis Report, nor the Technical Specification Bases are affected.
Therefore, the proposed changes do not involve a significant reduction in a margin of safety.
The NRC staff has reviewed the licensees significant hazards analysis and, based on this review, it appears that the three standards of 10 CFR 50.92(c) are satisfied.
Biweekly Notice Coordinator Therefore, the NRC staff proposes to determine that the amendment request involves no significant hazards consideration.
