j Commitment Revision- Spent Fuel Pool (SFP) Cooling System j

Establishment Of Database i The purpose of this letter is to revise a commitment previously submitted to the NRC in LER 96-037-00 "Sp.gnt Fuel Pool Coolina System Potentially inoperable Followina an 1

- SSE Due to Failure of Non Seismic Connectina Pioina." regarding establishment of a  !

' database linking licensing design basis to the component level for Maintenance Rule systems that are both safety related and risk significant. In the LER we stated that this

. database would be completed prior to entry into mode 4 from the current outage.

i Independent of this commitment Northeast Utilities initiated a program to develop 1 Design Bases Summary documents for Millstone Point Unit 3 safety related and risk j significant systems as determined by the Millstone Unit 3 Maintenance Rule evaluation process. Included in each system's Design Bases Summary document are the ,

regulatory design bases for the system and its components. The Design Bases  ;

Summary provides the link between the regulatory design bases and the  !

system / components requirements in a cost effective manner within an achievable time i frame. The Design Bases Summary documents for Maintenance Rule systems that are  ; i both safety related and risk significant will be issued prior to August 13,1997. /

The revised commitment is provided in Attachment 1.
