ES-401 ST-2010-05-RETAKE Written Examination Review Worksheet Form ES-401-9 Instructions

[Refer to Section D of ES-401 and Appendix B for additional information regarding each of the following concepts.]

1. Enter the level of knowledge (LOK) of each question as either (F)undamental or (H)igher cognitive level.
2. Enter the level of difficulty (LOD) of each question using a 1 B 5 (easy B difficult) rating scale (questions in the 2 B 4 range are acceptable).
3. Check the appropriate box if a psychometric flaw is identified:

The stem lacks sufficient 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.

The distractors are not credible; single implausible distractors should be repaired, more than one is unacceptable.

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

4. Check the appropriate box if a job content error is identified:

The question is not linked to the job requirements (i.e., the question has a valid K/A 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.

5. Check questions that are sampled for conformance with the approved K/A and those that are designated SRO-only (K/A and license level mismatches are unacceptable).
6. Enter question source: (B)ank, (M)odified, or (N)ew. Check that (M)odified questions meet criteria of ES-401 Section D.2.f.
7. Based on the reviewer=s judgment, is the question as written (U)nsatisfactory (requiring repair or replacement), in need of (E)ditorial enhancement, or (S)atisfactory?
8. At a minimum, explain any AU@ ratings (e.g., how the Appendix B psychometric attributes are not being met).

There are a variety of types of grid disturbances (eg, degraded voltage) that could result in a start of the EDGs and not a de-energization of the aux transformer. Therefore it could be argued there is more than one correct answer.

Source: Bank Distractor Justification A: CORRECT: MOV-0004A is a manual valve and therefore will not open on a Safety Injection. The SI actuation (Mode I) will not strip the bus before loading SI/ESF Equipment. That would only happen for a Mode II or Mode III.

B: INCORRECT: The HHSI pump will continue to run, but MOV-0004A will not open as it's a manual valve.

C: INCORRECT: The SI actuation (Mode I) will not strip the bus before loading SI/ESF Equipment.

That would only happen for a Mode II or Mode III. The HHSI pump will run on recirc though.

4/27/2010 Print Date STP LOT-17.1 NRC RO EXAM Given the following:

Unit 1 is in Mode 3.

Unidentified RCS leakage is 0.5 gpm and rising.

Some personnel have already entered Containment to investigate the cause of the leakage.

A second group of individuals is in the process of entering Containment.

During this second entry, the Primary Reactor Operator notes rising Containment Building pressure and radiation level due to a rise in RCS leakage.

Which of the following:

(1) correctly describes the effect on Containment as the entry is made, AND (2) is a required action for the Control room staff in accordance with 0PSP03-XC-0002A, Containment Entry and Partial Inspection (Containment Integrity Established) based on the above conditions?

A.

(1) Containment pressure will substantially lower.

(2) Initiate a Phase A Containment Isolation and direct personnel in containment to exit via the Auxiliary Airlock.

B.

(1) Containment pressure will substantially lower.

(2) Direct a Plant Operator to enter containment to notify personnel in containment of the rising leakage.

C.

(1) Containment pressure will not be appreciably affected.

(2) Monitor containment pressure, if it approaches 0.5 psig, then notify personnel in containment to exit immediately.

D.

(1) Containment pressure will not be appreciably affected.

(2) Immediately notify personnel in containment of the rising leakage by sounding the Containment Evacuation Alarm.

Answer: D (1) Containment pressure will not be appreciably affected.

(2) Immediately notify personnel in containment of the rising leakage by sounding the Containment Evacuation Alarm.

B: INCORRECT: Containment pressure should not change appreciably because entry and exit is made through one door at a time so containment integrity always exists. The action is not a procedural requirement. Sending additional personnel in containment under these conditions would not be desireable.

C: INCORRECT: The PERS AIRLOCK DOOR TRBL annunciator alarms whenever the door operating handwheel is rotated so this annunciator will alarm upon entry. 0.5 psid is the maximum operating pressure for the airlocks. The procedural requirement is to notify personnel as soon as containment conditions change.

B: CORRECT: The RCP Thermal Barrier is designed to cool incoming RCS water to the seal package if normal seal injection is lost. Normal seal injection flows TO the RCS therefore the seal package temperatures will remain the same. Because Thermal Barrier cooling is a backup method of cooling the seal, it should be restored as soon as possible.

C: INCORRECT: Seal inlet temperatures will NOT rise. The prescribed action is correct if seal injection flow to the RCP is lost.

Source: New Distractor Justification A: CORRECT: CCW flow throught the RCFCs is ~4 times higher than chilled water flow during normal plant ops. Although the cooling water flow is higher, RCB pressure will actually rise to the higher temperature of CCW compared to chilled water.

B: INCORRECT: RCB pressure will rise due to the higher temperature cooling flow through the RCFCs C: INCORRECT: Post accident flow through the RCFCs is higher.

D: INCORRECT: Post accident flow through the RCFCs is higher and RCB pressure will rise.
