ELECTRICAL POWER SYSTEMS BASES A.C. SOURCES, D.C. SOURCES and ONSITE POWER DISTRIBUTION SYSTEMS (Continued) restricted as noted in a letter from E. G. Adensam to L. F. Dale, dated 17 July 1984. The SSW pump load values are not used as the largest single load rejected from the diesel generators when testing to meet the requirements of Regulatory 4

Guide 1.9. Since the SSW system supplies cooling water to its associated diesel generator, tripping the SSW pump to perform this test would result in loss of the diesel generator.

~;

An exception is taken with respect to Regulatory Guide 1.108 requirements on the surveillance test frequency for the diesel generators in relationship to the number of valid failures. The test frequency provided in Table 4.8.1.1.2-1 provides adequate assurance of diesel generator availability without causing degradation due to excessive engine starts. The determination of valid failures on a per diesel generator basis reflects that failures on one diesel generator does not necessarily reflect the same problem on the remaining diesel generators.
