- 3. Gil 09/09/05 - concerned about K/A match.
- 4. Gil 09/26/05 - K/A mismatch. Relationship between containment isolation and EAL?
R: on a loss of T-20, RPS buss "B" is deenergized. This causes Primary CTMT isolation including isolation of RHR in SDC mode. The successful Applicant must recognize the reason PCIS isolated is the loss of RPS buss "B" and that the isolation interrupted SDC which must be restored to prevent entry into an EAL. If SDC not restored, the threshold for an EAL will be crossed.

Gil 09/26/05 - Correct answer is longest. Should balance with other distracters.
R: added full noun name descriptions to "B" and "C" for HPCI and RCIC. However, unable to perfect length of selections without degrading operational validity of the distracters or creating new psychometric clues.
Todd 09/30/05 - deleted "SSES Unit 1 is operating at full power. A failure of PSV152-F032B, the "B" Core Spray loop pump suction relief valve has lowered Suppression Pool water level.

SSES Unit 1 has an Anticipated Transient Without Scram (ATWS). The control room operating crew initiate Standby Liquid Control (SBLC) per LQ/Q-3. You observe the following:
- "A" SBLC Pump RED indicating light ILLUMINATES,
- "B" SBLC Pump RED indicating light does NOT illuminate,
- ONE SBLC SQUIB READY A-B White indicating light extinguishes,

A Determine & correct the cause for the "B" SBLC Pump failure to start and START it.
B INJECT Boron with RCIC IAW ES-150-002 to establish full flow.

18 Question Number:
2950 37 NRC K/A System/E/A System Number RO Justification New - inspired by Browns Ferry 2 exam of September 2001 (Question ID 21039)
SSES requires both SBLC pumps to start to ensure reactor safety following an ATWS. The expected flow rate is approximately 86 gpm. In this case, the flow rate is one-half of expected (43 gpm) because one SBLC pump failed to start. The alarm will energize when 4742 less 4587 (155) gallons have been injected. This will occur in 155 divided by 43 or 3.6 minutes.
The failure of one SQUIB Valve to fire has no effect on the solution because the pumps discharge to a common header.
The common header then flows through two parallel SQUIB valves.
A - Only one valve opened. Plausible if the Applicant believes that the failed SQUIB valve blocks SBLC flow to the RPV and that opening the valve will restore full flow.
C - LQ/Q-4 requires this if Boron can NOT be injected with SBLC. Here, SBLC is injecting, albeit at half the required rate.
D - SSES requires both SBLC pumps to start to ensure reactor safety following an ATWS References TM-OP-053 CFR Link Comments and Question Modification History Gil 09/09/05 - editorial change to stem Gil 09/26/05 - Distracter "A" not plausible with one pump running and one squibb fired; should have some flow.
R: revised "Never" to "16 minutes". Applicant may misapply pump laws.
Todd 09/30/05 - why give set point?
R: w/o set point, it may become LOD=5 because not expected to know this.
Rich 10/03/05 - K/A mismatch. CE view?
R: agreed. Changed stem and distracters to require Applicant to demonstrate ability to manipulate controls. Saved original question as 181.

- Ask SSES to evaluate distracter "C" as a potentially second correct answer.
SQ 10/14/05 - editorial changes to stem and answer.
SQ 11/04/05 - SSES considered distracter "C" to be second correct answer. Changed "RCIC" to "HPCI" to make it absolutely incorrect.
SQ 11/14/05 - changed answer to "Determine & correct the cause for the "B" SBLC Pump failure to start and START it."
to be more realistic. Control Room has little to do if SBLC pump fails to start otherwise.
SQ 11/28/05 - SSES to determine why 86 gpm is required. They questioned the wording. Verified requirement against the lesson plan. Changed distractor "C" back to RCIC based on SSES opinion that it is more plausible and clearly wrong.

CFR Link Comments and Question Modification History Gil 09/26/05 - Once a rod is scrammed (from any means) it will insert at the same rate (about 4 seconds).
Recommends:
A - All control rods will automatically insert in < 10 seconds.
C - All control rods will automatically insert in > 10 seconds.
R: no known basis for the 10 second threshold. Will request SSES input. Not sure I accept the proposition that all rods will insert at the same rate. Seems reasonable to believe that the rods for which the Scram Pilot Solenoid Valves did NOT open would move a bit slower because their air is vented through a smaller area.
09/27/05: Now understand the issue. All rods insert at the same rate once the scram valves open. However, for the affected 20 HCUs, the scram valves take longer to open. Must have SSES verify/evaluate the 10 second threshold.
Todd 09/30/05 - replaced "Both units are at full power when one unit scrams for unknown reasons." with "SSES Unit 2 scrams from full power."
SQ 10/14/05 - major changes to improve/clarify. Original not saved.
SQ 11/14/05 - no comments during validation week.
SQ 11/28/05 - SSES concerned that "B" is arguably correct because once the Scram Pilot Solenoid Valves finally open (when ARI & B/U scram valves vent the header) the Scram Discharge Volume will have some pressure in it. Therefore, the d/p between the HCU & Rod Control Hydraulics and the SDV will be reduced. This could cause the rod to move slower. SSES to investigate.

- A Reactor Scram condition is present.
- 24 Control Rods are at Position 04.
- All other Control Rods are at Position 00.
- Reactor Pressure Vessel level is stable at +35 inches.
- IRMs are not yet fully inserted.
Per EO-000-113, what is the status of the Reactor?
The Reactor IS shutdown and WILL remain shutdown under ALL conditions without Boron.
A The Reactor IS shutdown but WILL NOT remain shutdown under ALL conditions without Boron.
B The Reactor MAY NOT be shutdown and MAY NOT remain shutdown under ALL conditions WITH Boron C

74 Question Number:
NRC K/A System/E/A System Number RO Justification Per EO-000-113, LQ-2, the Reactor is shutdown and expected to remain shutdown under all conditions without Boron if no more than one rod position is greater than 00. Alternatively, with more than one rod above position 00, the Reactor is shutdown and expected to remain shutdown under all conditions without Boron if all Control Rods are inserted to the Maximum Subcritical Banked Withdrawal Position (MSBWP). For SSES Unit 2, the MSBWP is 02.
CHOICE (A) - No WRONG: SSES Unit 2 MSBWP is 02. Here, 24 rods are at position 04.
VALID DISTRACTOR: Applicant could erroneously apply Unit 1 data to Unit 2. Good question on unit differences.
CHOICE (B) - No WRONG: the Reactor can NOT be deemed shutdown under all conditions...
VALID DISTRACTOR: Applicant could erroneously believe that the Reactor is S/D but not assured to remain shutdown under all conditions...
CHOICE (C) - No WRONG: the reactor can NOT be deemed to be SHUTDOWN.
VALID DISTRACTOR: Applicant could erroneously believe that the Reactor will remain S/D even though it's not currently declared S/D with more than rod above 00.
CHOICE (D) - YES References Limerick Unit 1 exam of October 2002, (Question ID 24312)
EO-000-113, LQ-2 CFR Link Comments and Question Modification History Gil 09/28/05: Distracter C is implausible NO not shutdown and Yes it will remain shutdown. Change part (2) to Indeterminate. Need input from Reactor Engineering R: done.
Todd 10/05/05 - changed question call and choices from (1)-(2) selection to single bullet/sentence.
Harry 10/05/05 - changed distracter "C" from implausible "NOT S/D and INDETERMINANT" to more plausible "IS S/D but future status is INDETERMINANT".
SQ 11/04/05 - SSES does not like this question. Concern is that distracter "C" is not clearly wrong because all Operators are taught that S/D requires all but the most reactive rod fully inserted. Unable to reach resolution.
SQ 11/14/05 - generated significant discussion during validation week. Greatest concern is that Applicant could select "C" believing that a Reactor Engineer determined the Rx was S/D and would remain S/D. Editorial changes to stem, entirely new distractor "C" and reworded answer "D" to accommodate this concern. Saved original as 741.
SQ 11/28/05 - capitalized all instances of IS, WILL, NOT, MAY in the distractors per SSES suggestion.

78 Question Number:
The control room has been evacuated and, as Unit Supervisor, you are directing SSES Unit 2 operations from the Remote Shutdown Panel. The following conditions exist:
- Suppression Pool temperature is 86 degrees Fahrenheit and steady.
- Residual Heat Removal (RHR) pump 2P202A is running
- RHR is operating in the Suppression Pool Cooling (SPC) and Suppression Pool Spray (SPS) mode.
- Drywell Pressure is 1.2 psig and lowering.
- Reactor Pressure Vessel (RPV) pressure is 90 psig and slowly lowering.
- Reactor Pressure Vessel (RPV) water level is 60 inches and rising.
- You have directed the PCO to establish RPV water level above 90 inches and below 100 inches.
Which ONE of the following correctly describes your priorities?
Reconfigure RHR loop "A" to the Drywell Spray mode.
A Maintain Suppression Pool Cooling and Spray using either RHR loop.
B Reconfigure RHR loop "A" to the Shutdown Cooling mode using RHR pump 2P202A only.
C Locally start RHR pump 2P202C and use RHR loop "A" to provide SPC, SPS & Shutdown Cooling concurrently.

78 Question Number:
2950 16 NRC K/A System/E/A System Number RO Justification CHOICE (A) - NO WRONG: Drywell spray is not necessary because DW pressure is lowering via SGTS VALID DISTRACTOR: PC/P-7 requires DW spray if needed to reduce DW press and if RHR not needed for core cooling.
CHOICE (B) - YES EO-200-113 takes precedence over ON-200-009. SP/T-2 requires that RHR be used to maintain SP temps below 90.
ON-200-009 directs user to align RHR for SDC. The EOP has priority over the ON.
CHOICE (C) - NO WRONG: EO-200-113 takes precedence over ON-200-009. SP/T-2 requires that RHR be used to maintain SP temps below 90. ON-200-009 directs user to align RHR for SDC. The EOP has priority over the ON.
VALID DISTRACTOR: ON-200-009 directs the user to establish SDC.
CHOICE (D) - NO WRONG: Not possible because even with operation shifted to RSD, F004A and F006A are interlocked to prevent concurrent opening. Also, this would cross-connect the RPV with the SP through the RHR suction lines. Consequently, there is no procedure that directs this activity.
VALID DISTRACTOR: Plausible if the Applicant sees the conflict between establishing SDC and maintaining SPC/SPS but forgets the design of the RHR system.

- Complete loss of offsite power (LOOP).
- Steam leak inside the drywell.
- ESS bus1C (1A203) is deenergized due to a fault.
- All ON-100-101 (SCRAM, SCRAM IMMINENT) actions are complete.

2950 28 High Drywell Temperature EA2.04 4.1 4.2 Ability to determine and/or interpret Drywell pressure as it applies to HIGH DRYWELL TEMPERATURE NRC K/A System/E/A System Number RO Justification CHOICE (A) - NO WRONG: Core Cooling is assured by core submergence. With level at 27 inches and dropping by 2 ipm, it will take 78 minutes to reach L1 (-129) where LPCI will be needed.
VALID DISTRACTOR: Core cooling is a plausible alternative given the dropping pressure - especially if the Applicant sees a need to Depressurize.
CHOICE (B) - NO WRONG: Rapid Depressurization would be required if HCTL limits of Figure 2 or PSL limits of Figure 4 were threatened. The given conditions do NOT provide justification for depressurization.
VALID DISTRACTOR: SBLOCA could cause Applicant to depressurize and utilize low pressure ECCS injection sources.
CHOICE (C) - NO WRONG: DW spray lineup would be complicated by SPC and DW spray takes priority.
VALID DISTRACTOR: Temperature is above 90 deg F.
CHOICE (D) - YES Loss of 1A203 causes loss of RHR Pp 1C, CS Pp 1C, RHR SW Pp 1A, 1B230.
Loss of 1B230 causes loss of 1B236 which causes loss of "C" RHR valves.

- RBCCW HEAD TANK HI-LO LEVEL (AR-123-001, E06) annunciates.
- All other conditions in the plant are NORMAL.
- The NPO reports that RBCCW Head Tank level has been slowly rising since it was drained several hours ago and that all other RBCCW indications are normal.
- All Reactor Water Cleanup (RWCU) parameters are normal.
- Reactor Recirculation Pump (RRP) Motor Winding temperatures are normal.
Per established SSES procedures, the Operating Crew must drain the RBCCW Head Tank to 5/8 full again and...
... then swap CRD Pumps and isolate the previously running CRD Pump.
A
... then remove the RWCU system from service and isolate RBCCW to the NRHX.
B
... then swap RBCCW Heat Exchangers (1E201A/B) and isolate the previously in-service Heat Exchanger.

NRC K/A System/E/A Justification CHOICE (A) - No WRONG: This is a TBCCW load VALID DISTRACTOR: Might work for high TBCCW Surge Tank.
CHOICE (B) - No WRONG: This would be correct if higher radiation levels accompanied the high level. However, no radiation present.
VALID DISTRACTOR: correct if higher rad levels evident.
CHOICE (C) - YES CHOICE (D) - No WRONG: already did this once.
VALID DISTRACTOR: Per AR-123-001, E06 - time to suspect the RBCCW HX and isolate it.
References AR-123-E06 ON-114-001 Comments and Question Modification History Gil 09/26/05 - OK Rich 10/09/05 - If not immediate action, should we specify procedure?
R: the action required by answer "C" is part of the alarm response and not part of the ON. Given these indications and choices, the successful Applicant should be able to recognize "C" as the only answer that would address these conditions. "A" is obviously wrong because it is NOT a RBCCW load. "B" is wrong because all conditions are otherwise normal which implies no radiation or high temperatures to indicate NRHX leak. "D" has already been done and will not alleviate the continuing rise in level. I did add another bullet to drive the Applicant further away from "D".
Todd 10/17/05 part K/A at the RO level.
The following SSES Learning Objectives support this question:
10258 Given appropriate alarm response procedures, determine the following for any annunciator associated with the Reactor Building Closed Cooling Water System:
- 1. Probable cause of the alarm
- 2. Adverse consequences of continued operation in the alarm state
- 3. Appropriate course of action Applicant should be able to reason the correct course of action without the Alarm Response Procedure.
1676 Predict the effect that the following conditions will have on the Reactor Building Closed Cooling Water System:
- h. High or low RBCCW Head Tank level Unable to adequately test both ability to predict and use procedures of this two part K/A. Per authority of NUREG 1021, ES401, Section D.2.a., second paragraph [When selecting or writing questions for K/As that test coupled knowledge or abilities (e.g., the A.2 K/A statements in Tiers 1 and 2 and a number of generic K/A statements, such as 2.4.1, in Tier 3),
try to test both aspects of the K/A statement. If that is not possible without expending an inordinate amount of resources, limit the scope of the question to that aspect of the K/A statement requiring the highest cognitive level (e.g., the (b) portion of the A.2 K/A statements) or substitute another randomly selected K/A.], the test question tests the ability to predict the impact of an air dryer malfunction.
18 October 2005.
SQ 11/14/05 - added two additional bullets:
- All Reactor Water Cleanup (RWCU) parameters are normal.
- Reactor Recirculation Pump (RRP) Motor Winding temperatures are normal.
also changed STA to NPO and added Re-and again to "D" to emphasize that this was intended to be a repeat.
SQ 11/28/05 - significant changes. Added redraining the head tank to all distractors to improve plausibility and realism.
Changed Distractor "D" completely to eliminate a second correct answer. Original was merely to repeat the IMAs of the AR which was arguably correct.
