Dear Mr. Garchow:
Subject:
Palo Verde Nuclear Generating Station (PVNGS) Units 1,2 and 3 Docket Nos. STN 50*528/529/530 2009 Reactor Operator and Senior Reactor Operator Written Examination Results Arizona Public Service Company (APS) management has completed its review of the operator examination conducted November 6, 2009, thru November 13, 2009. The required examination documents referenced in NUREG 1021, Rev 9, Supplement 1, Section ES-501 (C.1.a) were hand-delivered or sent electronically to the chief examiner, with one exception.
APS will forward the original Form(s) ES-201-3, "Examination Security Agreement," with the appropriate pre-and post-examination signatures by December 15, 2009. This will allow time for APS to obtain signatures from the individuals who had detailed knowledge of any part of the operating tests or written examination.
There are no commitments made to the NRC by this letter. Please call Mr. Warren Potter, Department Leader Nuclear Training, at (623) 393-6165, if you have questions or require additional information.
Sincerely, TNW/FJO/gat cc: E. E. Collins NRC Region IV Regional Administrator L. A. Hurley NRC Region IV, Licensing Assistant, Operations Branch J. R.

- Wolf Exam Review SROQ2 SRO Q15 ROQl3 ROQ25 ROQ50 ROQ61 i Examinee many Question I would have picked the correct answer "c" if it had said go to the SPTAs rather than LOOP Aren't both answers A and B correct? If you take into account the allowed 3% blowdown then pressure could drop as low as 1212 psig. This would relate to 570 degrees, which is less than the 572 stated in the answer. If! had failed fuel wouldn't D I (high activity in the Letdown Heat Exchanger area) be true. Why is Battery breaker open a wrong answer? Per the LOCA SFSCs if all available All available Recombiners are in operation and H2 levels are < 4.5% then the safety Function is met. Given this I think that answer "C" (no action required unless hydrogen concentration approaches 4%) is also correct. Answer You have to go perform the SPT As prior to proceeding to an EOP. No change to the key. Recommendation:
No Change We agree this is being submitted to the NRC for review. Recommendation:
Accept both A and B as correct With full MSSV blowdown there may be a short time when temperature is lower but the expected response would be temperatures close to the MSSV setpoint.
The SBCS comes back in manual with 0 output due to the given conditions, therefore without Operator action 564 degrees is wrong. Recommendation:
No Change Yes, but this is not the purpose on the this monitor. We will consider submitting this change. Recommendation:
No Change It is not, this question is being submitted to the NRC for review. Recommendation:
Accept both A and B as correct The procedure requires actions to be taken if H2 is greater than 0.7%. No Recombiners available does not meet the requirement of all available Recombiners are operating.
Recommendation:
No Change I II SRO Question 15 deletion proposal Due to two answers containing conflicting information that the examinees were exposed to during the LOIT program, Palo Verde suggests that question 15 of the 2009 SRO Initial License exam be deleted from the exam per ES-403 D.1.c. The conflicting answers are: Answer "A" states; "only A02C is running " Answer "B" states; "A02B will start after a 120 second time delay...." This became apparent during the exam review process as well as interviews with the SRO examinees.
Interviews with candidates showed that ofthe 8 SRO candidates, 4 chose answer "B", 3 chose answer "A", and one candidate chose "D". All 4 candidates that chose answer "B" stated the referenced alarm response as justification for there answer. The conflicting information is contained in the Alarm Response Procedure 9RK7A, Panel B07A Alarm Response Procedure, Window 9B). The Alarm Response states the following:
- The Standby CEDMAir Cooling Fan starts after a Reset Time Delay. This conflicts with the next sentence in the Alarm Response Procedure: Backdraft dampers have been installed to allow any single CEDM Cooling F an to provide sufficient cooling. . In addition to the above, the following statement is also include on the same page of the Alarm Response procedure: IF the loss of one CEDM Fan in a CEDM ACU causes DP to fall below the auto start set point, OR the loss of two CEDM Fans in one CEDM ACU causes DP to fall below the auto start set point, THEN the standby CEDM Air Cooling Unit should auto start:.... Engineering was consulted to determine the correct answer based on the question.
The initial response from the system engineers was also in conflict.
The next step was to verify the response ofthe unit simulator.
It was verified that the simulator does not model the low DIP start function.
Auto starts are triggered by other means.
