SUBJECT:
DIESEL GENERATOR RELIABILITY CONSIDERATIONS
Dear Mr. Wyckoff:
Thank you for the viewgraphs outlining EPRI's alternative approach to resolving Safety Issue B-56, which you have discussed with NUMARC.
The NRC is developing guidelines for a reliability centered EDG reliability program which include both maintenance and surveillance aspects, and relates these to targets (or goals).
A copy of SAIC's prepared " Diesel Generator Reliability Program Review Guidelines," Revision #3 dated July 17, 1987, is enclosed for your information and use prior to the August 1987 meeting that we ciscussed.
This draft (Revision #3) is considerably different then the 'iworking drafts" which were discussed in late April 1987 and it appears to me that some of EPRI's expressed concerns (i.e., EPRI's viewgraphs) may be based on our early work, or even prior B-56 efforts.
I do not feel that B-56 will (nor should) continue to be a resolution dilemma.
Some of your points are indeed valid, particularly prior emphasis on a high frequency of quick starts.
Thus, I also want to make sure that these emerging B-56 reliability program guidelines relate to real world diesel generator operational considerations and minimize inadvertent damage due to over testing..
Therefore, let us plan a tentative meeting (say August 12, 1987) to discuss further EPRI's proposed approach to a reliability centered diesel maintenance program, including EPRI's proposed means to verify that an acceptable level of reliability (which can be verified) has been met.
This latter aspect is expected to be difficult to formulate and implement and should be brought forth now.
We have included such elements in our reliability program guidelines.
Therefore, please obtain the necessary NUMARC approvals, and identify meeting participants so that I can schedule a suitable room and notify appropriate NRC staff.
I believe that participation of INP0 staff would enhance the usefulness of this meeting.
Sincerely yours, 6
