Mr. ' Ibm Ippolito Division of Licensing Office of Nuclear Reactor Regulation United States Nuclear Regulatory Comission I
Dear Mr. Ippolito:
l l
'Ihis will confirm our discussion regarding CPSES Fire Dampers on May 24, 1984.
Our pre-operational test indicate some problems with assured fire damper closure under certain conditions.
We have reported this issue to NRC REG.IV as a potentially reportable deficiency under 10CRF50.55(e).
As I pointed out, this type damper behavior cnuld not have gone undetected.
Further, each case will need to be examined to determine safety impact and reportability.
We are proceeding with a rigorous review of alternatives to get the best l
solution of this issue and will provide you with a presentation of
}
the results as soon as possible.
Your attention to this matter will be appreciated.
Sincerel yours,
/
