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 27 Facility: Dresden Date of Exam: S/6I12 Scenario Numbers: 112/3 Operating Test Number: 11-1 (2012-301)
QUALITATIVE ATTRIBUTES Ini~ials 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':)
M~
- 3.
Each event description consists of the point in the scenario when it is to be Initiated the malfunction(s) that are entered to initiate the event nt~
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.
.~ ?
kt~
- 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:>
M~
- 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).

- 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.
