Review of Responses to Action Item e of IE Bulletin 85-03 Licensee:
Consumers Power 1945 ~est Parnell Road Jackson, MI 49201 Unit(s): Palisades Date of Response: 05-15-86 09-04-86 Respondent:
Kenneth W. Berry Director, Nuclear Licensing The information provided in your response to Action Item e of IE Bulletin 85-03 vas found to be deficient in some areas.
Please provide the additional information ~ecessary to resolve the following comments end questions:
- 1. UDlisteci MOYs M0-3041, -3045, -3049 and -3052 in discharge lines of the safety injection tank sy~te~ ere shown normally open (fail as is) on Dra~ing M-203, Sheet 1, Revision 29.
The possible problem that the system would be inoperable if the MOVs were left closed inadvertently should be addressed.
Based on the assumption of inadvertent equipment operations as required by Action Item a of the bulletin, revise Attachment A, Page 3 of 13, of the response of 05-1~-86 to include these valves.
- 2. Has veter hammer due to valve closure been considered in the d~termination of pressure differentials?
If not, please explain.
- 3. Please expand the proposed program for action items b, c and d of the bulletin to include the following details as a minimum:
(a) commitment to a training program for setting switches, maintaining valve operators, using test equipment end interpreting test results, (b) commitment to justify continued operation of a valve determined to be inoperable, and (c) description of a method possibly needed to extrapolate Talve stem thrust measured at less than maximum differential pressure.
- 4. Please submit a date for planned completion of Action Item f of the bulletin.
The specified due date is January 15, 1988.
