C Enclosure Request for Additional Information - Fire Protection Modifications 1.
The NRC staff, in a letter. dated May 19, 1980, requested that the
~
licensee install alternative shutdown capability 'indep'endent of the cabling and equipment in the control room, both cable spreading rooms (and adjoining cable chases), six cable chases, and other rooms containing unprotected redundant cables / equipment required for safe shutdown. The licensee has not committed or concisely stated that they comply with the above requirement. Therefore, state what areas of the Unit I require-alternative. safe shutdown system (s).and which areas meet the provisions of Section.III.G.2 of Appendix R.
2.
The BG&E submittal dated September 30, 1981 states that HPSI.will be used as a backup in c'ase the letdown system will not be available.
However during a conference telephone call dated December 19,.1981, amongBkL,NRC,andBG&E,youstatedthatHPSIwouldnotbeused or required. BG&E~should clarify their position regarding the role of HPSI in their alternative safe shutdown system.
3.
BG&E has not yet committed to providing the capability for achieving cold shutdown within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> as required by Appendix R to 10 CFR Part 50. Our position is that the licensee should meet this Appendix R requirement. Therefore, we require that BG&E clearly state that they will comply with this requirement.
4.
BG&E has not stated in writing that they will provide capability for monitoring source range flux or level indication for any sto' rage tanks used for alternative post fire shutdown, e.g., boric acid tank and the refueling storage water tank as part of the alternative shutdown capability.
It is our position that BG&E provide this commitment.
(Note: The tank level indication (s) can be indicated at the tank location).
5.
The licensee has not yet committed.to develop and implement written procedures pertaining to altermative shutdown.
It is our position that BG&E should provide this information.
