Dear Dr. Murley:
Reference 2 transmitted the results of a Safety Related Check Valve Audit conducted by the Nuclear Regulatory Commission (NRC) for Bymn Station. Based upon the results of the audit, five concems were identified. Response to these concems were pmvided by Commonwealth Edison Company (CECO) in reference 1. CECO actions identitied in reference I were completed as anticipated, with the exception of a portion of Concem #5; The following pmvides clarification as to the current status of that item.
Concem #5 addressed, " Corporate Nuclear Operations Directive (NOD-TS.9) allows for the use of the IST pmgnun testing as an indicator of check valve degradation in lieu of disassembly and inspection or diagnostic testing. The NRC Staff sequest ;ustification for using the IST progmm for this purpose."
CECO's response in part stated, " NOD-TS.9 will also be revised to clarify this position and delete the statements regarding deferral of check valve program inspections and diagnostic testing in lieu of IST testing by January 1,1994."

.. a result of CECO n: organization, which took place in early 1993, senior management request that.
i the use of Operations Directives be minimized and that the tecidcal requirements stipulated in these documents for various prognuns be incorporated into Technical Information Documents (TIDs). These
.l TIDs were intended to be used as generic guidance which nuclear stations may invoke on a site-specific basis via the use of station pmcedures, Regarding the response to Concem #5, CECO station management and the check valve coordinators were appraised of the desire to supersede the NOD-1 TS,9 with a TID which would pmvide guidance for station use on enhancing check valve.
j perfonnance. A draft TID was transmitted to the stations on December 27,1993, for station
~
comment. The finalized TID will be issued by March 31,1994. Upon release of the TID, NOD-TS.9.
will be cancelled.
If you have any questions conceming this matter, please address them to this office.
