Page 1 of 1 REQUEST FOR ADDITIONAL INFORMATION (RAI) RE.:

Unit (s): Millstone 2' Northeast Utilities Date of Response: 06-11-86 P. O. Box 270 Hartford, Connecticut 06141-0270 Respondent:
J, F. Opeka Senior Vice President The informatiOn.provided in your response to Action Item e of IE Bulletin 85-03 was found to be deficient in some areas.
Please provide the additional information necessary to resolve the following comments and questions:
- 1. Unlisted MOVs 2SI-614, -624, -634 and -644 in discharge lines of the safety injection tank system are shown normally open (FL) on Drawing 25203-26015 Revision 18.
The possible problem g
that the. system would be inoperable if the MOVs were left closed inadvertently should be addressed.
Base' on the assumption of inadvertent equipment operations as required by Action Item a of the bulletin, revise the table of the response.
of 06-11-86 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. Please expand the proposed program for action items b, e 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 and interpreting test results, (b) commitment to justify continted operation of a valve determined to be inoperable, and (c) description of a method possibly needed to extrapolate valve stem, thrust measured at less than maximum differential pressure.
4 Please submit and justify a date for planned completion of Action Item f of the bulletin.
As indicated by the response of 06-11-86, the specified due date of January 15, 1988 for Action Item f will not be met.
