The proposed amendmentwould revise TS 3.8.1 to permit extending the Completion Time (CT) from 14 days to 65 days for aninoperable emergency diesel generator (EDG). The proposed amendment would also revise theTS Surveillance Requirement 3.8.1.2 and 3.8.1.3 to extend the Surveillance Frequency (SF) from31 days to 82 days, or within 3 days following the inoperable EDG being restored to service, and TSSurveillance Requirement 3.8.1.7 to extend the SF from 92 days to 145 days, or within 3 daysfollowing the inoperable EDG being restored to service.
In order for the staff to proceed with its review of the proposed change, the following information is needed:
- 1. Please discuss in detail how CNP Unit 1 mitigates the consequences of the following events when plant is operating with one EDG in maintenance for 65 days. Please identify all additional power sources that are available and will be credited for mitigating the events described below for the duration of the extended outage including the operating procedures in place and the operator training completed.Please identify the capacity of the power sources, their alignment and the actual loads required to be connected, including the fuel oil requirement and storage for 65 days.
- b. Station Blackout
- 2. For question 1c, please describe how CNP Unit 1 meets the following regulatory requirements.
- a. 10 CFR 50.46,"Acceptance criteria for emergency core cooling systems for light-water nuclearpower reactors."
- b. Plant Specific Design Criterion (PSDC) 39 and/or 10 CFR 50, Appendix, General Design Criterion 17, Electric Power System.
