I l2l I I QUALITATIVE ATTRIBUTES lnitials a b*co The initial conditions are realistic in that some equipment and/or instrumentation may be out of service, but it does not cue the operators into expected events./7 tvl ftqq 2. The scenarios consist mostly of related events.u1 A tlr¿3. Each event description consists of the following o the point in the scenario when it is to be initiated. the malfunction(s) or conditions that are entered to initiate the event. the symptoms/cues that will be visible to the crew o the expected operator actions (by shift position). the event termination point (if applicable) w 4tø4. The events are valid with regard to physics and thermodynamics.

r//14 ttd" 5. Sequencing and timing of events is reasonable and allows the examination team to obtain complete evaluation results commensurate with the scenario objectives.

Pursuant to 10 CFR 55.46(d), any open simulator performance deficiencies or deviations from the referenced plant have been evaluated to ensure that functional fidelity is maintained while running the planned scenarios.
