Amendment 20 requires that measures be established to assure that conditions adverse to quality are promptly identified and corrected.

Contrary to the above, the control room annunciator alarm response for Main Feedwater Containment Isolation Valve (CFCIV) low nitrogen actuator pressure was inadequate, in that. pressure setpoints and immediate actions commensurate with the safety significance or allowed Technical Specification Action Requirement timeframe for a potentially inoperable valve. were not adequately specified. On April 3. 1997, this  !

contributed to the failure of the operations staff to take adequate and timely corrective actions to determine and restore operability of Unit 1 "C" CFCIV ICF-51 following receipt of a low actuator pressure alarm. As a result, actions necessary to determine valve operability were not

Jerformed until over 17. hours later. at which time pressure was found Jelow that necessary to ensure valve operability.
