Instructions

[Refer to Section D of ES-402 and Appendix B for additional information regarding each of the following concepts.]

1,

2.
3.

Enter the level of knowledge (LOK) of each question as either (F)undamental or (H)igher cognitive level.

Enter the level of difficulty (LOD) of each question using a 1 - 5 (easy - difficult) rating scale (questions in the 2 - 4 range are acceptable).

Check the a propriate box if a sychometric flaw is identified:

TRe stem lacks sufzient focus to elicit the correct answer (e.g., unclear intent, more information is needed, or too much needless information).

The stem or distractors contain cues (i.e., clues, specific determiners, phrasing, length, etc).

The answer choices are a collection of unrelated true/false statements.

One or more distractors is not credible.

One or more distractors is (are) partially correct (e.g., if the applicant can make unstated assumptions that are not contradicted by stem).

Check the a propriate box if a.ob content error is identified:

TRe question is not linked to the job requirements (Le., the question has a valid KIA but, as written, is not operational in content).

The question requires the recall of knowledge that is too specific for the closed reference test mode (i.e., it is not required to be known from memory).

The question contains data with an unrealistic level of accuracy or inconsistent units (e.g., panel meter in percent with question in gallons).

The question requires reverse logic or application compared to the job requirements.

4.

New. Do the SDC pum s auto tri when the SDC system is isolated whether they are aligneffor shutd30wn cooling or mixing? More than one correct answer (ie A,)?

RESOLUTION: Licensee clarified reference: Both pumps will trip on low suction pressure when isolated. There is only one correct answer.

11 5.

Check questions that are sampled for conformance with the approved WA and those that are designated SRO-only (KIA and license level mismatches are unacceptable).

11 6.

Based on the reviewers judgment, is the question as written (U)nacceptable (requiring repair or replacement), in need of (E)ditorial enhancement, or (S)atisfactory?

7.

At a minimum, explain any U ratings (e.g., how the Appendix B psychometric attributes are not being met).

ES-401 E

Written Examination Review Worksheet Dresden August 2004 Exam New. 1) The third condition in the stem states: SBLC Pump Discharge Pressure sliqhtly ABOVE Reactor Pressure, while on page 13, Section 6.a.b) of the Lesson Plan provided states that when 2 pumps are running, discharge pressure can be up to 235 psi above reactor pressure due to line losses (which is more than slightly above reactor pressure). If the intent is to show that the SBLC pumps are NOT running deadheaded, then add a condition in the stem to state what reactor pressure is (e.g., 300 psig) and then state in the third condition in the stem what the SBLC discharge pressure is (e.g. some number that is well below the SBLC relief valve setpoint - - 500 psig). 2) On the question worksheet, it gives importance values of 3.813.9 and references A I.04 for the WA. This should be changed to 3.6/3.7 or Al.O6(?) to match ES 401 sheet?

RESOLUTION: 1 ) Intent is NOT to show not running deadheaded but rather that pressure is high enough to inject. 2) WA reference changed from AI.04 to AI.06.

New. Question asks for function of HPCI-8 valve, but reference describes HPCl485.

RESOLUTION: Licensee clarified reference. The injection valve is the HPCl 8 valve, and the HPCl turbine does not spin until the 4 and 5 valves are open.

New.

New. 1) In the stem it is stated that UZ3 DG jacket water temperature is 205 deg F and increasing. This could only be the case if the U2/3 DG was NOT tripped (and thus provides a Cue that the bus associated with the UZ3 DG is still energized). Delete the phrase and going up 1 deg F every 5 minutes. 2) Distractor D is NOT plausible, since one would NOT expect both Core Spray pumps to be fed from the same bus. To make distractor D plausible, suggest adding another condition in the stem that the alarm Generator Differential Current is present on the U2 DG, which would imply that the U2 DG is tripped. Then change the correct answer to distractor B.

RESOLUTION: Licensee incorporated NRC comments as stated.

1) There was NO question uestion indicating the WA (?WA 212000 A2.14?); question source, LOK, original question, etc. 2) Is the Hi Level Scram setpoint above the Hi Level alarm setpoint? If so, then just because the alarm is in does NOT mean that a manual reactor scram is required The alarm response only places the mode switch in SHUTDOWN if a reactor scram occurs.

. 1) Added question reference sheet, NRC verified question

WA 212000 A2.14. 2) A-I4 alarm is the scram setpoint.

New 1) This question IS at the SRO level, since an RO would NOT be expected to know from memory Tech Specs requirements that require actions at greater than one hour (IO CFR 55.43.b (2)). 2) Is there a Tech Spec associated with Control Rod Position indication while at power that could be applicable instead of TS 3.1 3?

RESOLUTION. 1) Question asking TS entry condition. ROs are required to recognize TS applicability. Added explanation that TS 3.1.3 is applicable to Modes 1 and 2, removed last two sentences from reference on LCO information 2) No.

New To make the wording between distractors B and D consistent, change the word "halt" in distractor B to "stop".

RESOLUTION. Upon further review by the licensee, they identified a procedure compliance issue that resulted in no correct answer. Licensee revised the question Form ES-401-9 Psychometric Flaws I

2) Change the times for the following: -17:17:45, Division I, ECCS > 100 psig Discharge Permissive. With the above changes to the time line, the correct answer becomes distractor B.

RESOLUTION: Licensee justified testing applicant knowledge of concepts associated with each of the question distractors and answer. Proposed changes would narrow the focus and test fewer concepts. NRC will leave as written.

RESOLUTION: NRC reviewed original question, verified new question modified.

Bank. Distractors B and C are NOT plausible (to have a switch associated with the CCSW pumps to be associated with initiation of drywell sprays).

Suggest taking the condition of 316 in MANUAL out of the question stem and having rewording distractors to be associated with various positions/conditions associated with the 31 6 and 31 7 switches.

a. SNa: Startup of 2nd RRP w/ Failure of Discharge Valve to Open.

Primary Water via RWCU Following a Gp 3 Isolation.

I ) Add sim setup instruction note about placing DW pressure controllers to MAN and closing the valves.

2) Errata, fix grammar in cue: DOP 0202-01 has been...
3) Licensee requested JPM critical step time change from 2 to 5 minutes for securing RRP when the discharge valve fails to open. DOP 0202-01 directs the operator to trip the RRP within two minutes of starting if the associated RRP discharge valve fails to open after starting.

Based on discussions with manufacturer and verification on the simulator that running the RRP deadheaded for 10 minutes showed no rise in bearing temperatures, the SOS stated that he would consider the step performed unsatisfactorily if the RRP was not secured within 5 minutes.

I ) JPM Step 13 states, Adjust RMC 2-1290-1 3 controller.. ; whereas Step 12 of DOP 1200-02, states

..adjust RMC 2-1290-14...

2) Incorrectly identified as Alternate Path.
3) JPM Step 5 not critical.

I)

Done.

2) Done.
3) The licensees comment was not incorporated because there was no intent to change the procedural guidance. The expectation to trip the RRP within two minutes of the discharge valve failing to open is still valid, and remains a critical JPM step.
1) Change Step 13 to state

...adjust RMC 2-1209-14 controller.,.

2) Removed mark for Alternate Path on JPM attribute page.
3) Leaving the PIC controller in Balance has no effect on JPM outcome as setup.
