ENCLOSURE SEQUOYAH NUCLEAR PLANT NUREG-0737, Item I.C.6 - Verify Correct Performance of Operating Activities TVA Response,- Current plant administrative procedures require:
(a) The alignment of all systems and conponents important to safety be verified prior to unit startup.
(b) Changes in the alignment of any system important to safety be recorded on a system status sheet.
(c) Shift personnel being relieved communicate information on any abnormal plant condition including temporary conditions.
(d) System operability be demonstrated before a system is returned to service, and (e) Approval _by the shift suservisor or his representative prior to the performance of any activity on any systems important to safety, or any activity that may effect systems inportant to safety. The shift supervisor or his representative is notified when an activity authorited to be performed on a system impoi. ant to safety is completed or a change occurs in the scope of the activity.
Plant operating instruutions require completion of a startup checklist prior co unit startup. This checklist is used to verify correct alignment of all systems important to safety, In addition, alignment of systems important to safety are reviewed each shift.
Anytime a critical component is changed'from its normal position or condition, a system status sheet is completed and placed in a system status folder. Panel checklists are reviewed each shift to verify proper panel alignment exists for all system; important to safety.
TVA has completed the review of plant instructions and made the necessary changes.
It is TVA's opim n that this verification function can be performed adequately by an assistant unit operator (AUO) and that the ise of licensed unit operators is not necessary. The'AU0 has sufficient training and familiarity with plant systems-to ensure correct system' alignment,
.and this policy will allow the licensed operator to remain in the control room.
1 Equipment important to safety'is defined as the reactor coolant system (pressure boundary; components) and associated pressurizer and pressure relief system, the' residual heat removal. system, engineered safety feature systems,. engineered safety features electric power systems, and cooling water systems necessary to operate the.above systems.
