Initial Conditions - Those conditions set forth in the drill scenario that must be met before the
drill can be initiated.
Objective - Specific measurable performance objectives that are used for drills. These
objectives are designed to demonstrate or test specific portions of participants'
knowledge of facility operations.
Observer - One who is responsible for observing a drill, but who is not authorized to interact with
facility operating personnel.
Restoration - The return of facility equipment to a desired and specified condition to permit
continued operation. Identification of final facility condition following the normal
completion of a drill scenario.
Simulation - An enactment representing a real situation. Specific events of the scenario may be
simulated for practical reasons during a drill (operations of critical facility equipment,
entrance into high radiation areas, etc.).
Termination Conditions - (1) Those conditions as described in the drill scenario that when met
terminate the drill and restore the facility to a safe condition. (2) Those limits, established
in the drill scenario, that if exceeded during the conduct of the drill require an immediate
halt to the drill and a return to a safe and stable condition.
