ILT 2014 NRC Written Exam Analysis

1. 6 Questions >50 missed.

2. Knowledge deficiencies identified for the following:

• Procedure 5.1RAD entry conditions.

• The lowest DW pressure which will exceed PCPL-A with high PC water level.

• Where the RCIC Steam Supply line drains are routed to during normal plant operation.

• Location of RHR system orifices.

• The impact of manually operating Torus to Drywell and Reactor Building to Torus vacuum breakers on primary containment and reactor building pressures.

3. No substantive changes.

Chief Examiner's Note:

Question 10: 60% missed - chose C Question 11: 60% missed - chose A (2) / D (1)

Question 38: 80% missed - chose D Question 56: 80% missed - chose C Question 59: 60% missed - chose B Question 65: 60% missed - chose A (2) / D (1)

Licensee determined all 6 questions represented applicant knowledge deficiencies which were remediated. Attached reference questions redacted, can be found in Final Written Exam file (ML15351A357).

NLS2015142 Page2 of2 The Task Standard should be revised to state "On completion of this JPM, the applicant started and, then, shuts down RPS MG Set A after determining voltage cannot be maintained within the required operating band," removing the statement "without adjusting the potentiometer."

A procedure change request has been initiated to eliminate the CAUTION statement and replace with steps to direct "If VOLTAGE ADJ potentiometer setting has been changed while shutdown, then place the potentiometer at approximately the midpoint position."

This letter contains no new regulatory commitments.

Should you have any questions or require additional information, please contact me at (402) 825-2788, or James Florence, Simulator Supervisor, at (402) 825-5700.

12/15/2015 MEMORANDUM From: T.J. Farina To: NRC Reviewers Subj: Cooper Nuclear Station Request for Post-Exam Change to JPM P-1 Cooper Nuclear Station is requesting a change to the task standard for JPM P-1, which was administered on Dec 3. The task involves starting an RPS MG Set which had been secured for maintenance. Once the MG Set is started, voltage cannot be stabilized and the applicant is expected to secure the MG Set (alternate path).

The approved task standard reads:

On completion of this JPM, the applicant started and, then, shuts down RPS MG Set A after determining voltage cannot be maintained within the required operating band without adjusting the potentiometer.

The requirement that the applicant not manipulate the voltage adjustment potentiometer is based on a caution statement prior to Step 5.1.3.1 of procedure 2.2.22, which reads:

Caution - VOLTAGE ADJ potentiometer setting shall not be adjusted unless it is known that setting has been changed while RPS MG Set A was shut down.

The JPM was written with the understanding that this caution applied to all substeps under 5.1.3 (steps 5.1.3.1 through 5.1.3.6), and that the applicant therefore should not manipulate the potentiometer at any point in the JPM. However, post-administration, the licensee has stated that this caution only applies to the substep immediately following it, 5.1.3.1, and that when the applicant identifies that AC Voltage is out of tolerance in step 5.1.3.5, he is in fact permitted to manipulate the VOLTAGE ADJ potentiometer.

Please review the enclosed materials, and provide a recommendation regarding Cooper Nuclear Stations request to modify the JPM. The TAC for this exam is X02547.

Regards, T.J.

• • • RESOLUTION***

On 12/16/2015, Region IV examiners Clyde Osterholtz and John Kirkland formed a post-exam review panel, and concurred with the licensees recommendation to remove the phrase, without adjusting the potentiometer from the approved JPM P1 Task Standard. The final JPM will be revised accordingly.
