[m IE Bulletin 79-28, NAMOD Limit Switches

\

Dear Mr. Martin:

IE Bulletin 79-28 required that certain actions be taken if NAMOD EA180 liriit switches were installed or planned to be installed in any safety-related equipment at Diablo Canyon Power Plant.

Our letter to Mr. R. H. Engelken, dated June 18, 1981, informed the NRC that the actions raluired by IE Dulletin 70-28 for Unit 1 had been completed. It also identified twelve (12) switches raluiring corrective action in Unit 2.

This letter informs you that the top cover gaskets in the twelve limit switches in Unit 2 have also been replaced in accordance with the nnnufacturer's recaTendation enclosed with the Bulletin. No further action is deemed necessary, ry truly yo rs, 4

for Philip A. t' rane, J f ..
