Simulator Scenario Test Item (Question/JPM/Scenario, etc.)

Concern or Problem Recommended Resolution Reference Remarks Question #2 Caroline Buckingham (55-73009)

B is incorrect. A containment isolation from the control board gives a T-signal to close 427, which then reopens on the loss of air to containment caused by the same signal.

Initiating a CI from the control board would have an end result of 426 being open.

CI does not prevent 427 from being re-opened, as its failure position on a loss of air is open.

There is no correct answer, remove question from Exam ATT-11.0 33013-1887 The stem clearly states that the question is asking what signal prevents OPEN operation, NOT valve operation on loss of Instrument Air.

Enhance wording in 2nd part of question statement by changing re-open to operate Recommend NO change to Exam.

Question #67 John Whitman (55-63285)

The NOTE on page 10 of O-1.2 gives examples of alternate power level indications, but is not intended to be an all inclusive list. Step 6.8.1 shows that RCS temperature is an acceptable indication of power.

All answers are correct, remove question from Exam O-1.2 Steam Dumps are placed in service in pressure control mode at 1005 psig in step 6.7.9 of O-1.2, the difference between Tavg and 547F gives an alternate indication of Reactor power. Furthermore, step 6.8.1 of O-1.2 states WHILE monitoring diverse indications of Reactor power level (pressure, flows AND temperature),

CONTINUE power ascension using control rods AND steam dumps.

specifically calling out temperature as a diverse indication of Reactor power. This means that all four indications presented in the question stem are indications that can be used to confirm

Accept both answers (B and D) as correct ECA-1.1, Step 7 ECA-1.1, Step 7.a states Establish and maintain cooldown rate in RCS cold legs - LESS THAN 100°F/HR. A-503.1, Section 3.3 states Maintain implies a continuing action.

Therefore, Tcold would also be monitored during S/G depressurization.
