OPERATING TEST CHECKLISTS AND NRC COMMENTS FOR THE DRESDEN RETAKE EXAMINATION - JAN 2003

Submitted Operating Test with NRC Comments Contains the following:

Letter Exelon Cover letter transmitting the operating test ES-301-3 Operating Test Quality Checklist ES-301-4 Simulator Scenario Quality Checklist Three (3) dynamic simulator scenario guides (ES-D-1 & ES-D-2) There were no NRC comments made on the submitted examination. Only one minor change was made to one scenario based on simulator response during the validation of the scenario.

a.

The operating test conforms with the previously approved outline; changes are consistent with

/

samplin requirements e.g., 10 CFR 55.45, operational importance. afet function distribution.

b.

There is no day-to-day repetition between this and other operating tests to be administered kI during. this examination.

.1 C.

The operatinig test shall not duplicate items from the applicants' audit test(s)__(see Section D. 1.a).

41)Aw

d.

Overlap with the written examination and between operating test categories is within accep limits.

0

e.

It appears that the operating test will differentiate between competent and less-than-competent a plicants at the desi nated license level.

2. WALK-THROUGH (CATEGORY A & B) CRITERIA

a.

Each JPM includes the following, as applicable:

• initial conditions

• initiating cues

• references and tools, including associated procedures

• reasonable and validated time limits (average time allowed for completion) and specific designation if deemed to be time critical by the facility licensee

• specific performance criteria that include:

- detailed expected actions with exact criteria and nomenclature

- system response and other examiner cues

- statements describing important observations to be made by the applicant

- criteria for successful completion of the task

- identification of critical steps and their associated performance standards

- restrictions on the seguence of steps, if aplicable

b.

The prescripted questions in Category A are predominantly open reference and meet the l**

criteria in Attachment I of ES-301.

C.

Repetition from operating tests used during the previous licensing examination is within acceptable limits (30% for the walk-through) and do not compromise test integrity.

d.

At least 20 ercent of the JPMs on each test are new or significantly modified.

3. SIMULATOR (CATEGORY C) CRITERIA

a.

The associated simulator operating tests (scenario sets) have been reviewed in accordance with Form ES-301-4 and a copy is attached.

1.

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.

... 2.

scnaio cnitm syofrlated events.

Aid)*

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 the symptoms/cues that will be visible to the crew namics the expected operator actions (by shift position)It the event termination point if applicable)

4.

No more than one non-mechanistic failure (e.g., pipe break) is incorporated into the scenario 1.1/

without a credible precedingl incident such as a seismic event.

Vo

5.

The events are valid with reg1ard to physics and thermodynamics.

• L

6.

Sequencing and timing of events is reasonable, and allows the examination team to obtain complete evaluation results commensurate with the scenario objectives.

7.

If time compression techniques are used, the scenario summary clearly so indicates. Operators have sufficient time to carry out expected activities without undue time constraints. Cues are given.

8.

The simulator modeling is not altered.

9.

The scenarios have been validated. Any open simulator performance deficiencies have been evaluated to ensure that functional fidelity is maintained while running the planned scenarios.

410 PC

10.

Every operator will be evaluated using at least one new or significantly modified scenario. All other scenarios have been altered in accordance with Section D.4 of E$-301.

.4C**t

11.

All individual operator competencies can be evaluated, as verified using Form ES-301-6 (submit t*

the form along1 with the simulator scenarios).

12.

Each applicant will be significantly involved in the minimum number of transients and events specified on Form ES-301-5 (submit the form with the simulator scenarios).

13.

The level of difficulty is appropriate to support licensin decisions for each crew position.
