Dear Mr. Rusche:

~ t, Your letter dated August 13';>> 1976 from D. L. Ziemann requests analyses and results regarding effects on operability of safety related equipment due to plant operation and equipment failures during a degraded grid voltage'ondition.

Duei:to the complexity of the analyses we find that we cannot supply these analyses and results by the date requested and we therefore must request a 60-day extension from the date ok this letter in order to supply the required information.

Very truly. yours,
