Florida Power and Light Company's (FP&L) response to IEB 85-03, " Motor Operated Valve Common Mode Failures During Plant Transient Due to Impoper Switch Settings," for.your St. Lucie facility.
The review of the responses, dated May 15, October 13, and October 31, 1986, indicates the need for additional information before the program to assure valve operability can be approved.
The information provided in your response to Action Item e of IEB 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 V-3614, -3624, -3634 and ~3644 in discharge lines of the safety injection tank system are shown locked open (fail as is) on Drawing 8770-G-078, Sheet 131, Revision 3, for Unit 1.
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 the listing of the respanse of 05-15-86 to include these valves.
NOTE:
For Unit 2, see Drawing 2998-G-078, Sheet 132, Revision 0.
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 signature testing equipment and interpreting signatures, and (b) commitment to justify continued operation of a valve determined to be inoperable.
