Subject:

Diablo Canyon Diesel Generator Load Tests We have reviewed your svbm.,ittal dated July 31, 1981 in regard to diesel generator load tests and find that the tests demonstrate compliance with the guidelines delineated in Regulatory Guide 1. 9 except for one minor frequency variation.

The.frequency variation was slightly below the 95% frequency lower recommended limi;tIfor less than one second; the Diesel Generator showed strorig recovery capability demonstrated by return to within the frequency limi't within less than 0.035 seconds; this meets the objective of Regulatory Guide 199, and is, therefore, acceptable.

Sincerely, cc:
