Dear Mr. Tiernan:
LTripp, RI ACRS (10)
SUBJECT:
REQUEST FOR ADDITIONAL INFORMATION - PROPOSED PUMP AND VALVE INSERVICE TESTING PP0 GRAM (TACS 64976 & 64977)
The NRC staff has evaluated your proposed inservice test (IST) program for safety-related pumps and valves as provided in your letter of February 26, 1987 and as modified by your submittals dated March 30 and July 5, 1988. The staff has determined that additional information is necessary. The request for additional information is enc 1csed.
The NRC staff issues IST Safety Evaluation Reports based upon review of the complete IST program plan. This program plan must included all modifications or revisions made subsequent to the submittal of the originally proposed IST program.
Consequently, it is requested that you provide a complete, revised IST program plan in response to this request for additional information which includes your IST program plan modifications as presented in your letters of March 30 and July 5, 1983.
Please provide this revised IST program plan within 70 days following the issuance of this letter.
If additional time is needed, please inform us of your proposed schedule within 35 days of this letter's issuance date.
The reporting and/or recordkeeping requirements of this letter affect fewer than ten respondents; therefore, OMB clearance is not required under PL 96-511.
Sincerely, 9%21%ned by

PROVDTED INSERVICE TESTING PROGRAM VALVE PROGRAM 1.
All valves that perform a safety-related function must be included in the IST program and tested to the requirements of ASME,Section XI. The staff's position is that the emergency diesel generators (EDGs) perform a safety-related function.
Therefore, all appropriate valves in the EDG air start system (including the ai. start solenoid valves) and in the fuel oil transfer system must be included in the IST program and tested in accordance with the Code requirements.
BG&E's justification, submitted in the July 5, 1988 letter, for not including these valves in the IST program is not acceptable.
2.
Both submittals (March 30 and July 5, 1988) contain a relief request number A-3.
Although these two relief request are numbered the same, they deal with relief from different Code requirements. Both requests appear to be valid.
In the program resubmittal, the licensee should assign a new number to one of them.
3.
In the March 30, 1988 submittal, relief request nurnbered AF-1 is inadequate.
In order to detemine the adequacy of the request, technical justification must be added to the basis for not testing the valves at cold shutdowns.
4 In the March 30, 1988 svbmittal, relief request number SI-7 is inadequate.
The basis contains no technical justification for extending the testing interval beyond quarterly and the alternate testing refers to a testing interval of "ITP."
The staff is not familiar with a testing interval designated by the abbreviation "ITP."
PUMP PROGRAM 1.
All pumps that perform a safety-related function must be included in the IST program and tested to the requirements of ASME,Section XI. The staff's position is that the EDGs perform a safety-related function.
Therefore, the fuel oil transfer pumps must be included in the IST program and tested in accordance with the Code reqeirements.
BG&E's justification, submitted in the July 5,1988 letter, for not including these pumps in the IST program is not acceptable.
7.
In the March 30, 1988 submittal, the basis and alternative testing of relief request number 7 must be clarified. When higher flow tests are performed at reduced frequency, all data normally required on a quarterly frequency must be taken.
The proposed alternative testing section of the relief request infers that only flow rate data will be taken during the higher flow test.
