Subject:

Grand Gulf Nuclear Station Docket No. 50-416 License No. NPF-29 Required 30 Day Response To NRC Generic Letter 96-06 l

GNRO-9 6/ 00122 Gentlemen:

NRC Generic Letter 96-06 requires each addressee to j

submit a written response on or before October 30, 1996 indicating (1) whether or not the requested actions will be completed, (2) whether or not the requested information will be submitted and (3) whether or not the requested information will be submitted within the requested time period.

The purpose of this letter is to inform you that Grand Gulf Nuclear Station will determine if containment air cooler cooling water systems are susceptible to either waterhammer or two-phase flow conditions during postulated accident conditions; and if piping systems that penetrate the containment are susceptible to thermal expansion of fluid so that overpressurization of piping could occur.

If any systems are found to be susceptible h

to any of these conditions, Grand Gulf Nuclear Station j (3')

f will assess the operability of affected systems and take 9611050005 961029 PDR ADOCK 05000416:
