DRAFT Wednesday, October 08, 2008 Page 1 of200
FOR REVIEW ONLY - DO NOT DISTRIBUTE 2008 SRO NRC Examination QUESTION 1 D General Discussion OMP 1-7 General Statements of Philosophy:
An ATWS (Anticipated Transient Without Scram) is defined in 10CFR50.62 as an anticipated operational occurrence followed by the failure of the reactor trip portion of the protective system. To have an ATWS there must be a transient followed by a failure of the reactor trip breakers.
Instrument failures, by themselves, are not necessarily transients. For example, if one channel of Pressurizer Pressure was out of service for preventive maintenance (bistable in tripped condition) and another Pressurizer Pressure channel failed (not the controlling channel), a reactor trip signal would be generated. If the reactor failed to trip, this would be a failure of the reactor trip breakers and the automatic trip features of the reactor protection system and not an ATWS event. (PPRB OPS-9283)
Also, OTDT runback would occur if rods are in AUTOMATIC Answer A Discussion Plausible: An invalid reactor trip is present as defined by OMP 1-7. To manually trip the reactor would be correct if it was a valid reactor trip.
Answer B Discussion Plausible: An invalid reactor trip is present as defined by OMP 1-7 This is not an ATWS. The shutdown would be correct due to being in TS required shutdown.
Answer C Discussion Plausible: This is a failure of the RPS system per OMP 1-7 To manually trip the reactor would be correct if it was a valid reactor trip.

Choices Band C are for LOCAs IN containment. Choices A and B are for shutdown conditions as stated in AP/27 which do not apply to this situation based on the stem.
Answer A Discussion He may interpret "shutdown" in the title as Mode 3. This is a common point of confusion. When AP/27 is used, it does transition for this situation to API 19 Answer B Discussion There is a transition to APII 0, however he should realize it's a LOCA outside containment based on EMF-41 and NDINS sump room.
Answer C Discussion This is a valid EP flowpath for a leak in the NCS. But not for a LOCA outside containment.

Answer A Discussion This would be true at low power level or in mode 3 where N16 is not present or at low concentrations Answer B Discussion Incorrect: Not a sensitive method of comparison - requires large gpm leak rates before this is noticeable.

Answer A Discussion Incorrect: I KC-345A does not close immediately.
Plausible: This would be correct except the valve closes after a 30 second delay Answer B Discussion Correct: NCP seal cooling is being maintained by NY. IKC-345A closes after a 30 second time delay.
Answer C Discussion Incorrect: All seal cooling is not lost. The seal bypass valve is on a common line from all 4 NCPs - not just the IC NCP.
Plausible: Ifhe thinks that seal cooling is lost, opening the seal bypass valve would enhance seal cooling to the NCP.
Answer D Discussion Incorrect: This would be correct if all seal cooling is lost in this mode.
Plausible: If the candidate does not understand that seal cooling is supplied by the NV with this alann.

FOR REVIEW ONLY - DO NOT DISTRIBUTE 2008 SRO NRC Examination QUESTION 35 A General Discussion REPLACEMENT KIA An 86S relay causes 2ETB to lockout. The blackout signal will not be overridden by the blackout signal, however, a LOCA signal would override the 86S relay and attempt to load LOCA loads. Therefore neither B train pump will re-start. On a normal LOCA or LOOP, both trains ofKC would actuate.
Answer A Discussion ICORRECT Answer B Discussion If the student thinks that either train BIO causes both trains to start (could be confused with RN which causes both units pumps to start on either unit LOCA or B/O) 2A2 will not start.
Answer C Discussion IIf student thinks that the B/O signal will override the 86S relay. This would be correct if a B train only were to occur.

0200 - 1A DIG Battery Charger 1DGCA fails.
0700 - DIG 1A Panel, E/5 "LOSS OF DC CONTROL POWER" - LIT 0900 - A tornado results in a complete loss of the switchyard.
Assuming no actions have been taken to address the failed charger, which one of the following statements correctly describes the operating status of the 1A DIG and the reason for this status?
A. The 1A DIG starts because the auto-start function is not dependent on DC control power.
B. The 1A DIG starts because the loads of the failed charger are supplied from vital power through auctioneering diode 1VADA.
C. The 1A DIG did not start because it has lost all control power.
D. The 1A DIG started but did not tie to the bus because the sequencer has lost all control power.
