Question #81 student comment. (docket #55-62645)

The stem of this question stated to determine the required procedure and the current status of offsite power. I concluded from the stem information that there was a clear delineation between the "required" statement, applying to the procedure and not applying to the "current" status of power operability. I did not, at the time of the exam, believe that the stem was unclear or confusing and did not ask the proctor for clarification.

I believe that this question has two correct answers for the following reasons:

1.

GOI-6 Section AA is entered for the condition stated in the root, due to the Transmission Operator notifying the control room of an "unanalyzed" grid condition.

In accordance with the required procedure, GOI-6, Section AA; Section 3.0:

"NOTE 6* Entry into LeOs 3.8.1.1 and 3.8.1.2 is a conservative action at this time" Based on Note 6, I applied the option stated in the note to declare the current offsite status as inoperable and entered the applicable LeOs.

Based on the procedural guidance of GOI-6, it is acceptable to declare offsite power sources inoperable due to the unanalyzed condition stated in the stem, therefore making answer B or A correct. (See attached copies of procedure steps/notes)

2.

Based on the stem description of "currenf operability status of offsite power sources, I assumed that when contacted by the Transmission Operator that they implied a certain amount of inoperability in the grid just by being in an unanalyzed condition. I assumed then that the current status of offsite power was inoperable.

In conclusion, based on the unclear information in the stem of the question regarding current status of offsite power and by applying the conservative actions specifically delineated in Note 6 of the required procedure, GOI-6, Appendix AA, I think answers "B" and "A" should both be considered valid answers to this question.

Sequoyah Nuclear Station response; After reviewing the information provided in question #81 and the guidance provided in GOI-6, "APPARATUS OPERATIONS", Section AA, "ACTIONS FOR CONDITION RED OR YELLOW OFFSITE POWER SOURCES", we agree with the candidate on his interpretation of offsite power operability. It is reasonable that the candidate could conclude that offsite power may in-fact be inoperable given the conditions provided in the stem of the question. The candidate would then be correct to make a conservative decision on the operability of offsite power and thus enter Tech Spec LCO 3.8.1.1 actions as stated in NOTE 6.

We recognize that the direction provided by Section AA, is not as clear as it could be on providing the expected actions should this condition be encountered. Thus the station has generated SR 138821 (GOI-6 weakness) to review the direction provided for determining offsite power operability and expected time frames in which this determination should be completed. Also this revised procedure clarification will be aligned with OPDP-8 guidance on operability determination (Le. must have reasonable assurance of continued operability) to ensure consistency.

Based on the guidance in ES-403, Section D, since the two conditions of "An and "B" are mutually exclusive (Le. offsite power cannot be operable and inoperable at the same time) we recommend that question #81 be deleted from the exam.

QUESTIONS REPORT for 2010 Feb SRO exam post-Atlanta 1. 077 AG2.2.44 081 Given the following:

Both units are at 100%.

The Transmission Operator informs the control room staff that the grid/offsite power conditions are in an unanalyzed condition due to the total system load exceeding the maximum analyzed system load for the current transmission system conditions.

Capacitor Yard Bus Voltage is :

A 164.3 B 164.2 C 164.3 0-REC-241-2, Frequency Recorder Potential 120v AC indicates 60 Hz.

Which ONE of the following identifies the required procedure and the current operability status of offsite power sources?

QUESTIONS REPORT for 2010 Feb SRO exam post-Atlanta DISTRACTOR ANAL YSIS:

A.

Correct, GOI-6 is the procedure the crew would implement in response to the conditions and the voltage and frequency is not out of limits as indicated in the question stem. Appendix AA has a 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> allowance for evaluation to determine if off site power is operable.

B.

Incorrect, GOI-6 is the procedure the crew would implement in response to the conditions and with voltage and frequency not out of limits, the offsite sources are not immediately inoperable. The 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> allowance for evaluation of operability does apply. However if either the voltage or frequency had been outside of allowable values, both sources would have to be immediately declared inoperable.

C.

Incorrect, Plausible if candidate thought that because voltage and lower than normal the regulator was not working and that the excitation required manual control and both sources being operable is correct pending the four allowance for evelauation.

D.

Incorrect, Plausible if candidate thought thatbecause voltage and lower than normal the regulator was not working and that the excitation required manual control and both sources would be inoperable if the voltage or frequency had been out of allwable values (out of limits) becasue the 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> allowance for the evaluation is not allowed.

NOTE 2 If voltage exceeds limits of 6876V (Low) or 7236V (high) for three minutes, then XA-55-EC86A, window 14, CSS Transformer Auto-Tap Changer Abnormal, will annunciate and the tap changer locks in its present position.

NOTE 3 To manually adjust voltage, ensure L TC-X or L TC-Y control switch (as applicable) is in manual (pushed in). To raise voltage, raise tap by turning handle in the clockwise direction.

To lower voltage, ensure LTC-X or LTC-Y control switch (as applicable) in manual (pushed in) and lower tap by turning handle in the counter clockwise direction.

NOTE 4 Start bus 1A or 2A voltage is monitored using 1-EI-57-55 or 2-EI-57-55 respectively on M-1 main control boards. Start bus 18 or 28 voltage is monitored using 1-EI-57 -56 or 2-EI 56 respectively on M-1.

NOTE 5 Off-site Power availability requirements with Tap Changers in Manual are contained in Section F and 15E500-3.

The following issue was identified following the NRC written exam administered on 3/3/2010:

GOI-6 Section AA provides guidance for off-site power being in an unanalyzed condition. This section directs performing an operability determination within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. If in an unanalyzed condition due to grid load exceeding the previous analyzed limit, the intent is that off-site power may still be considered operable pending completion of the analysis of the new load condition as long as grid voltage and frequency are within limits. If the 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> clock expires prior to completing the analysis, then the procedure directs declaring both offsite power sources inoperable. One license candidate was confused by the existing guidance and decided to immediately declare both off-site power source inoperable (without waiting for the operability determination within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />). Please clarify this procedure section to make this guidance clearer and to ensure that this section is consistent with OPDP-8 guidance on operability determinations (i.e. must have reasonable assurance of continued operability).
