REQUEST FOR ADDITIONAL INFORMATION (RAI) RE:
Review of Responses to Action Item e of IE Bulletin 85-03 Licensee:
Niagara Mowhawk Power Corporation 301 Plainfield Road
- Syracuse, New York 13212 Unit(s): Nine Mile Point 2
Date of Response:
05-12-86 02-18-87
+11-13-87
+This response to Action, Item f has not been reviewed completely.
Respondent C. V. Mangan, 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.
Provide the additional information necessary to resolve the following comments and questions:
- l. If MOVATS is planned for application to some MOVs which are not included in its data
- base, commit to and describe an alternate method for determining the extra thrust necessary to overcome the pressure differentials for these valves.
- 2. Revise Table 1 of the response dated 02-18-87 to include RCIC Turbine Trip and Throttle MOV 150, or justify its exclusion.
This valve is identified as MOV X on Page 74 of BWROG Report NEDC-31322 dated September
- 1986, and is shown normally open in Zone J-8 of Drawing 12177-PID-35B-4.
This MOV is listed in the response for one other GE Class 5 facility.
Assume inadvertent equipment operations, as required by Action Item a of the bulletin.
How would operation of the RCIC Turbine be ensured if this valve were to be (a) actuated inadvertently to the closed position upon intended initiation of the system or (b) left closed inadventently?
3.
The proposed program for action items b,
c and d of the bulletin is incomplete.
Provide 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,
~
hlAR 14 1988 Page of 2
RAI for Nine Mile Point 2
(b) description of a method possibly needed to extrapolate valve stem thrust determined by testing at less than maximum differential pressure, and (c) consideration of pipe break conditions as required by the bulletin.
Note:
A partial review of the response dated ll-'13-87 indicates these comments apply to it as well as to the earlier response.
