APPENDIX B NOTICE OF DEVIATION Carolina Power & Light License No. DPR-62 Based on the results of the NRC inspection conducted on December 15, 1981 through January 15, 1982, certain of your activities eppear to deviate fran your commitments to the Commission as indicated below:
Appendix M. Response H5.33 of the Final Safety Analysis Report states that complete isolation of each core spray room exists up to Elevation 20';
that pipe chases exist between core spray and residual heat removal (RHR) pump rooms, however the pipe chases are sealed to prevent flooding; that the RHR and high pressure coolant injection (HPCI) pump rooms are sep-arated by walls from -17' up to Elevation + 5'; and that no single, postulated event could occur which would compromise this mechanical sepa-ra tion. Water tight bulk head doors are provided for access to the HPCI room from each RHR room.
Contrary to the above, on December 22-23, 1981, during power operation a pipe chase between the north core spray and north residual heat removal roans was opened to allow pumping water fran the north RHR sump to the north core spray sump.
Additionally, on December 28-30, 1981, both watertight doors to the HPCI room were open during reactor operation.
With both HPCI room doors open, common mode flooding could occur between the north RHR, HPCI, and south RHR rooms.
