REGION 11 COMMENTS ON CRYSTAL RIVER RESPONSE To lEB 79-05 AND 79-05A Coc:::ents are keyed to the numbered response in Florida Power Conoration-response dated April 9,1979.
Item 1
~
Coment (1)
The response to the concern of a stuck open electronatic relief valve refers to the small break LOCA analysis. Whils this is accurate, the response should be addressed to a loss of feed flow transient, not to a small-break.
Item 3 The licensee should provide curve of pressure-teeperature relationships a
for voiding concerns to the operators in the control room.
Item 4(a)
Response is not clear as to how ESFAS will be teminated. That is, will the signal be " bypassed" or " reset".
" Reset" being the preferred nethod since " bypass" precludes further automatic action.
Item 5 Cocoent (1)
Response does not address the positions of emergency feed pump suction valve, EEV3 and EFV4 and manual suction valve EFV-36 (reference Fig. 10-2A in FSAR).
All of these valves should be open. Inspector has verified that these valves are kept open.

as of April 13, 1979.
RII inspectors have verified that licensee actions indicated in these responses (items 1 through 3, 4.a and 5) have been implemented at Crystal River.
