REQUEST FOR ADDITIONAL INFORMATION PROPOSED TECHNICAL SPECIFICATION FOR STANDBY SHUTDOWN FACILITY (SSF)
OCONEE NUCLEAR STATION, UNIT NOS. 1, 2, AND 3 TAC NOS. 66390, 66391 AND 66392
- 1. The proposed Technical Specification (TS) is not clear regarding the allowable status of the reactors (a) during scheduled and unscheduled SSF system inoperability periods, especially for extended inoperability periods and (b) during inoperabilities of the SSF Reactor Coolant Makeup System corresponding to individual reactors. Provide the appropriate clarifications in sufficient detail, including examples, to facilitate understanding. Provide rationale for any changes to the proposal.
- 2. Describe the degree to which the events for which the safety functions of the SSF are intended and the reliability and effectiveness of the SSF, if needed to function, are affected by the operability status of the hydroelectric generators and other emergency power sources. Provide the basis and rationale for the above.
- 3. Provide rationale for not providing compensatory measures in the proposed TS, whereas compensatory measures were provided in the previous TS proposal.
- 4. Clarify, with concise rationale, the justification provided for the additional seven (7) day hot shutdown period which is not provided in the Oconee TS for similar safety systems.
