x Docket: 50-382 E_ 2 9 W Louisiana Power & Light Company ATTN: J. G. Dewease, Senior Vice President l Nuclear Operations .

317 Baronne Street New Orleans, Louisiana 70160 l Gentlemen:

Thank you for your letters of May 14, 1986, and October 1, 1986, in response to IE Bulletin 85-03, dated November 15, 1985. As a result of our review, we find that additional information is needed.

Specifically, the infonnation provided in your response to Action Item e was found to be deficient in some areas. Please provide the additional information necessary to resolve the following ccmments and questions.

1. Unlisted MOVs SI-331A, -331B. -332A, and -332B in discharge lines of the safety injection tank system are shown locked open (fail as is) on Drawing LOV-1564-G-167, Sheet 2, Revision 22. If power is removed from the motors in addition to the locked-open position of these MOVs, please state this in your response. Otherwise, address the effect of assuming inadvertent equipment operations as required by Action Item a of the Bulletin, and revise Attachment 1 of the response of May 14, 1986, to include these valves.

2. Has water hammer due to valve closure been considered in the determination of pressure differentials? If not, please explain.

3. Listed MOVs 1025-1 and 1075-1 of the EFW system are 4-inch globe valves, and listed MOVs SI-506A and SI-506B of the HPSI system are 3-inch globe valves. We were advised recently that the M0 VATS data base does not include globe valves with orifice sizes less than 1.75 or greater than 2.0 inches. Will representative samples of these 3-inch and 4-inch globe valves be tested at full differential pressure? If not, explain and justify how settings will be verified for full differential pressure, RIV:RSB/ES f ./
