Dear Mr. Keppler:
Attachments A and B are Toledo Edison's follow-up responses to IE Bulletin 79-05C for the Davis-Besse Nuclear Power Station, Unit (DB-1) concerning reactor coolant pump operations.
These discuss the analyses and development of preliminary operator guidelines for reactor coolant pump operations.
Attachment A is the continued evaluation of Short Term Action Item Number 2 discussed in Toledo Edison's letter of August 29, 1979 (Serial No'.-1-85).
It is noted that this analysis was* completed for a lowered loop. reactor coolant system configuration and is a conservative evaluation for the raised loop DB-1 design.
Attachment B is a _ revision to Section III of the " Analysis Summary in Support of an Early RC Pump Trip" also transmitted in our August 29, 1979 letter. This revision replaces entirely the previously submitted Section III.
Very truly yours, Richard P. Crouse Vice President - Energy Supply
