2012 DRESDEN NUCLEAR POWER STATION INITIAL EXAMINATION PROPOSED EXAM FILES

• ES-301 Simulator Scenario Quality Checklist Form ES-301-4

• ES-301, Page 25 of Facility:

Dresden Date of Exam: S/6I12 Scenario Numbers: 1 12/3 Operating Test Number: 11-1 (2012-301)

QUALITATIVE ATTRIBUTES a b* c# 1. The initial conditions are realistic, in that some equipment and/or Instrumentation may be out of j' -service, but it does not cue the operators Into expected events. 2. The scenarios consist mostly of related events. "i':) 3. Each event description consists of

• the point in the scenario when it is to be Initiated

1. • the malfunction(s) that are entered to initiate the event -;::>

• the symptoms/cues that will be visible to the crew

• the expected operator actions (by shift position)

• the event termination point (if applicable)

4. No more than one non-mechanistic failure (e.g., pipe break) is incorporated Into the scenario ;:t ? IWtJ without a credible preceding incident such as a seismic event. 5. The events are valid with regard to physics and thermodynamics. ? 6. Sequencing and timing of events is reasonable, and allows the examination team to obtain complete evaluation results commensurate with the scenario objectives.

t::> 7. If time compression techniques are used, the scenario summary clearly so indicates.

fJ Operators have sufficient time to carry out expected activities without undue time constraints.

? ctt., Cues are given. S . The simulator modeling is not altered. , "'i:> 9. The scenarios have been validated.

Pursuant to 10CFA55.46(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.

10. Every operator will be evaluated using at least one new or significantly modified scenario.

1!-? -frJ All other scenarios have been altered in accordance with Section 0.5 of ES-301. 11. AU individual operator competenCies can be evaluated, as verified using Form ES-301-6 (submit the form along with the simulator scenarios). ? 1M" 12. Each applicant will be significantly involved in the minimum number of transients and events t". i) "'-'t1 specified on Form ES-301-5 (submit the form with the simulator scenarios).

13. The level of difficulty is appropriate to support licensing decisions for each crew position. 'D "'-if Target Quantitativa Attributes (Per Scenario; See Section D.5.d) Actual Attributes
