Response to NRC letter cated October 22, 1979 " Requesting Acoltional Information on Fire Protection Safe Shutcown Analysis".
This information was transmitted to the NRC in letters to T.A.
Ippolito from R.F.
Janecek catec January 23, 1980, February 29, 1980, and June 6, 1980 A fire area has recently been identified where a fire could impede safe shutcown and which has not been included in earlier suomittals on safe shutcown.
The area identified is the DC Distribution Center for each unit.
A fire in this area could result in the loss of 125v OC power to cotn safety civisions for the unit in which a fire is postulated.
Corrective action is Deing taken which will isolate DC power in this fire area for one safety civision from the seconc safety division with a three hour fire barrier.
Details of this analysis and design modifications will be suomittea by May 19, 1981.
The work associated with this modification will be completed in accordance with Paragrapn 50.48(c)(A).
