Infrequently Performed Tests or Evolutions

DOE-STD-1041-93

respond to and mitigate plant transients. These deficiencies are repaired expeditiously.

Compensatory actions for equipment deficiencies that significantly affect plant operation should

be established and thoroughly communicated. These compensatory actions anticipate all

operating conditions. The operating crews thoroughly understand the status of all equipment,

how it affects overall plant operation, and required compensatory actions.

When assessing equipment deficiencies, the effect that the deficiency has on operator ability to

respond to plant transients and emergencies should be included. Also, equipment deficiencies in

the aggregate should be reviewed to determine their combined or cumulative affect on the

operators during plant transient response. Equipment deficiency effects should be assessed

frequently enough to determine how emergent equipment problems affect plant operators.

Equipment deficiencies should be prioritized and categorized to support timely resolution.

4. Infrequently Performed Tests or Evolutions

The operations department has a lead role in ensuring that infrequently performed test or

evolution briefings are conducted prior to evolutions that may affect plant conditions. Thorough

briefings of all personnel involved should be held and possible adverse consequences of the test or

evolution addressed, as well as contingency plans for potential problems. Before any test or

evolution is conducted that is outside the bounds of normal plant procedures, the operating crew

supervisor should verify that the activity has been reviewed and approved. Supervisors should

confirm that their crews have written guidance and training to perform activities successfully.
