Valid Question. Answer @) is conect and distractors are wrong. Distractor (C) was selected.
For Diseactor C the candidate assumedthat Secondary Containment Isolation Valves, and that these valves would go closed on a High Dryrvell Pressure condition, which is a comon misconception among licensed operafor candidates.
However, although úeF6l2613 formpart ofthe secondary containment, &ey do NOTreceive an automatic closure signal on Hig Dr'well Pressure as most other Secondary Containmelrt Isolation Valves do.

Correct Total Correct Valid Question. Answer (A) is conect and distractors are !!rong. Distactor (C) was selected.
The candidate determined that the decay heat generated l0 minutes after shutdown is above the capacity of one, but within the capacity of two Low-Low Set SRVs. This is a common misconception because most candidates readily remember that decay heat drops to 7%owithn several seconds of a plant shutdown, due to the decay ofdelayed neutrons and they determine thatT%o is the capac ofabout one and a halfSRVs.
Valid Question. Answer (C) is conect and distactors rre wrong. Distractor (B) was selected.
This question is P&L based and the stem directly references requirements of the SOP. Lesson material also referenced the P&L this question is based on. Candidate stated they could not remember the range of the P&L.
Valid Question. Answer (C) is conect and distractors are wrong. Distractors (A) & (B) were selected. Candidate did not understand how control power aligned.
Valid Question. Answer (A) is correct and distractors are wrong. Distractors (C) & (D) were selected. Candidate used disjointed reasoning to arrive at answers.
Comment (Students)
Candidate F question is not about what the plant will do.Facil Response:Base on the stem ofthe question, actual plant response is not the answer. The question is about the capaclty of SRVs not about a timeline of events in which an SRV opens.
Candidate Feedback:
Good Question.
Facil Response:
None.
