E.
E.
Uan Brunt, Jr.
Executive Vice President Project Director 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.
Has water hammer.due to valve closure been considered in the determination of pressure differentials2 If not, please explain.
- 2. Listed MOVs HV-30 through.HV-33 and HV-54 of the AFW System are 4-inch globe valves, and listed MOUs HC-321 and HC<<331 of the HPSI System are 3-inch globe valves.
We were advised recently that the MOVATS data base does not include globe valves with orifice sizes less than 1.75 or more than 2.0 inches.
Will representative samples of these three-inch and four-inch globe valves be tested at full differential pressureP
- 3. Please explain why the following MOVs in the AFW system are not included in the tables of the response of 06-30-86.
(a)
HU-1 and HV-4 are shown normally closed in a suction line from the CST to one of the motor-driven pumps, in Zone E-3 of Drawing 13-M-CTP-001, Rev 14
'b)
HV-1142 and HV-1143 are shown in parallel in a line bypassing discharge of one of the motor-driven pumps to Steam Generator 1, in zones G-14 and F-14 of Drawing 13-M-SGP-002, Rev 17.
(c) HV-1144 and HV-1145 are shown in parallel i'n a crossover line between discharge l'ines. of the motor-driven pumps, in Zone C-14 of Drawing 13-M-SGP-002, Rev 17,
- 4. Please expand the proposed program for action items b, c and d
of the bulletin to include a commitment to a training program for setting switches, maintaining valve operators, using signature testing equipment and interpreting signatures,
