Enclosure REQUEST FOR ADDITIONAL INFORMATION CONCERNING PRESSURIZED THERMAL SHOCK AND REGARDING THE "150 DAY" RESPONSE TO NRC LETTER DATED AUGUST 21, 1981 FOR OCONEE 1 DOCKET NO. 50-269 Concerning Operator Actions
- 1. Provide an analysis or basis to justify the time assumed for correct operator action in the Overcooling Transient Evaluations, and in the Steam Line Break Evaluations.
- 2. In the cases for the overcooling transients and steam Tine break analyses, provide an evaluation of the-sensitivity of the transients to the time assumed for.operator action (i.e., if the operator isolates the feedwater 5, 10 or 20 minutes later than assumed or restarts a RCP 10'or 20 minutes later than assumed, what are the-resulting pressure/
temperature transients?).
