SRO Q-7            44%        Question asked for 2 preferred methods of contamination control during a SGTR/LOOP event. All candidates who missed the question chose distracter B which included increasing the cooldown rate to 100 degrees per hour. The SGTR procedure limits the CD rate to 30 degrees during a LOOP due to ensure asymmetric cooldown.
The question is valid as written.
SRO Q-13            44%        Question asked what signal would stop the SG overfill event and which EOP should be entered.
All picked correct signal MSIS but some chose Reactor Trip vs. Excessive Steam Demand. The excessive cooldown required ESD to be entered.
The question is valid as written.
SRO Q-21            33%        Question asked Operability status of ECCS (HPSI pumps) with the A DG OOS and a subsequent loss of the B HPSI pump room essential cooler.
The correct answer on the worksheets and answer key was both HPSI pumps Inoperable. All those who missed chose distracter C which stated that A HPSI was operable if the PBA-S03 was powered by offsite power, this can be considered correct since TS allows a 4 hour period before A HPSI must be declared Inoperable. A & C are both considered correct answers.
