Reference:
(1) Letter, T A Ippolito (NRC) to L 0 Mayer (NSP), dated April 25, 1980 The referenced letter requested that NSP provide a schedule for completing evaluation of minimum ECCS equipment availability with a DC power supply failure for the Monticello Nuclear Generating Plant.
An evaluation of the effects of DC power supply loss irrespective of the break location or type has been conducted.
(Refer to Attachment 1.)
That evaluation is being expanded to consider loss of equipment due to water spillage.
We are continuing our investigation and expect to submit an updated list of available ECCS equipment by August 30, 1980.
l Should you have any questions, please contact this office.
