MEDFORD TELEPHONE MANAGER. NUCLEAR LICENSING (818) 302-1749 June 20, 1986 Director, Office of Nuclear Reactor Regulation Attention: G. E. Lear, Director PWR Project Directorate No. 1 U. S. Nuclear Regulatory Commission Washington, D.C.

Subject:
Docket No. 50-206 Revised TDI Diesel Generators M/S Program San Onofre Nuclear Generating Station Unit 1
Reference:
Letter, R. F. Dudley (NRC) to K. P. Baskin (SCE) dated May 27, 1986, Transamerica Delaval (TOI) Diesel Engine Reliability and Operability Enclosed for your information are copies of Revision 2 of the "TDI Diesel Generator Design Review and Quality Revalidation Report," as applicable to the San Onofre Nuclear Generating Station, Unit 1.
As requested by the referenced letter, Southern California Edison hereby agrees to comply with all provisions of this revised Maintenance/
Surveillance program. However, we have one comment as explained below.
On page II-A-2 of the Generic Maintenance Matrix it is stated that the nineteen (19) diesel engine operating surveillance parameters that are listed in Table 1 of the Matrix "are to be recorded and/or checked [hourly]
during the monthly testing and any other period of operation."
We interpret this provision to apply only to those diesel operations which are of at least one hour duration and which are non-emergency related.
In an actual plant emergency, it would not be a prudent use of operator resources to carry out the full scope of surveillances whose purpose is to establish trends in diesel performance.
