Authority to Operate Equipment cont'd

DOE-STD-1041-93

Appropriate controls should be established to minimize distractions in the control room

such as excessive overlapping or simultaneous evolutions. The crew should be augmented

with additional operating personnel during complex normal or infrequently performed

evolutions, such as plant startups, plant shutdowns, or special tests.

Sufficient supervision should be provided to implement emergency plan requirements until

additional resources can be summoned.

Duties that require control room operators or supervisors to leave the control room to

respond to emergency conditions should be limited. For example, assignment of control

room operators and supervisors to fire brigade or medical response duties or to

communicate with outside agencies is carefully considered against the need for these

personnel to be in the control room during possible concurrent plant transients.

Difficulties have been encountered when these support functions were assigned to control

room personnel; therefore, other appropriately trained personnel are assigned these

responsibilities.

Sufficient nonlicensed operators or additional licensed operators should be provided to

perform normal, abnormal, and emergency shutdown activities outside the control room.

These operators are not assigned other duties that could interfere with these

responsibilities, such as fire brigade or emergency medical response duties.

To the extent possible, assigned responsibilities in an emergency should be the same

as those during normal day-to-day activities.

The possibility of simultaneous transients on both units should be considered when staffing

dual-unit sites.

Clear guidance should be provided to operating crew supervisors for managing crew resources.

To monitor and reinforce expectations for crew resource management, crews should be observed

and coached during normal plant operations and during simulator training. Simulator casualty

training is routinely performed with the minimum staffing levels expected during actual plant

casualties.

Shift technical advisor (STA) functions are implemented with a dedicated, qualified individual or

with a combined SRO/STA position. In either approach, the STA role is a key team role that

fosters monitoring and independently assesses the appropriateness of crew response to casualties.
