- HPI flows on C16: 120 gpm, 125 gpm, 115 gpm, 180 gpm
- P36B is inoperable due to maintenance.
- EDG #1 tripped and will not run.
Select the most appropriate action below for this situation:
- a. Close the HPI valve with 180 gpm flow to isolate break.
- b. Stop HPI pump P-36C to reduce break flow.
- c. Throttle HPI valve with 180 gpm flow until flow is 145 gpm.

Answer:
- c. Throttle HPI valve with 180 gpm flow until flow is 145 gpm.
Notes:
Answer [c] is correct since only one HPI pump is in service and although SCM has not been established, HPI flow must be throttled due to possibility of an HPI line break robbing flow.
Answer [a] is incorrect, although high HPI flow thru one nozzle would be indicative of a break in this line, the line should not be isolated.
Answer [b] is incorrect although stopping HPI pump will stop possible LOCA pathway on that train, it is incorrect since only one pump is running.

LPI/HPI flow rates for the past ten minutes have been as follows:
- "A" LPI flow--2900 gpm
- "B" LPI flow--2850 gpm
- "A" HPI pump flow throttled to 100 gpm through CV-1220
- "C" HPI pump flow throttled to 100 gpm through CV-1285 An overcurrent has resulted in an A-3 bus lockout and A-1 to A-3 tie breaker A-309 trip. The operator should:
- b. Close A-308 to power A-3 from #1 EDG.
- c. Energize bus B-5 from bus B-6
- d. Start P-36B to supply 100 gpm train through CV-1220.
Answer:
Notes:
"a" is the only correct action with the loss of the A-3 bus and the "A" LPI pump. The criteria for throttling HPI is contingent upon both LPI pumps flow >2800 gpm OR one LPI pump >3200 gpm, therefore full HPI flow must be restored on the only running HPI pump. "b" and "c" are actions to restore proper electrical alignment but they do not address the immediate need of maintaining proper core cooling. "d" is incorrect since flow is only supplied at the 100 gpm rate.

Reference:
41.7 / 45.7 Tier: 1 RO Imp: 4.0 RO Select: No Difficulty: 2 Group: 3 SRO Imp: 3.8 SRO Select: Yes Taxonomy: C Question:
The main fuel bridge has a spent fuel assembly in route to the RB upender when a seal plate NI cover failure occurs.
Water level in the canal is falling at two inches per minute.
The main fuel bridge operator should:
- a. Continue to the upender and place the assembly in the upender.
- b. Leave the fuel assembly in the mast and evacuate the area.
- c. Place the assembly in the fuel rack in the deep end of the canal.
- d. Return the assembly to any available location in the reactor vessel.
Answer:
- d. Return the assembly to any available location in the reactor vessel.
Notes:
In this scenario the fuel transfer canal level is decreasing rapidly and thus shielding for the spent fuel assembly will be decreasing rapidly and the fuel assembly must be placed in an area that will remain covered with water after the canal is drained.
Therefore, "d" is the only correct answer. "a" is incorrect as this is a time consuming maneuver and the transfer tube should be isolated anyway to prevent losing level in the SFP. "b" is very incorrect since this will expose the assembly to atmosphere and dose rates will be lethal for quite some time. "c" is incorrect since the deep end will not contain enough water to keep the assembly covered.

The plant had been operating at 100% power for 200 days.
Following a plant trip, preparations for startup are in progress.
The CBOR is performing "Calculation of Estimated Critical Configuration" (Worksheet 1) per Reactivity Balance Calculation, 1103.015.
At a given boron concentration, which of the following post-trip times would result in the highest rod index due to the effects of Xenon ?

Answer "b" is correct since xenon has peaked at it's highest concentration pre-trip resulting in the highest rod index.
Answer "d" is incorrect since Xenon is essentially depleted at ~80 hours following a reactor trip from 100%
power (thumb rule), thus adding essentially no reactivity for which rod withdrawal must compensate for.
Answer "a" is incorrect since xenon is still building in at this time and is not at its peak value, and "c" is incorrect because at this time the core is moving towards being xenon free.

Given:
- Power escalation to 60% power is in progress.
- Current reactor power is 40%.
- There are 3 RCPs in service.
- "A" RCP is out of service due to an electrical fault in breaker H-11 (Reactor Coolant Pump P-32A).
Which of the following conditions would cause an automatic reactor trip?
- a. Annunciator "RCP TRIP" (K08-A6) is clear, RCS flow is lowering and "C" RCP amperage is zero on SPDS.
- b. Annunciator "RCP TRIP" (K08-A6) is in alarm, RCS flow is lowering and "H2 L.O. RELAY TRIP" (K02-A5) in alarm.
- c. Breaker B-7146 (ICW Booster Pump P-114A) trips open and P-114B fails to auto start causing a loss of RCP Seal Cooling.
- d. Breaker H-21 (Reactor Coolant Pump P-32D) trips open due to an over-current condition causing a loss of the "D" RCP.
Answer:
- b. Annunciator "RCP TRIP" (K08-A6) is in alarm, RCS flow is lowering and "H2 L.O. RELAY TRIP" (K02-A5) in alarm.
Notes:
(b.) is correct. The indications are for a loss of H2 bus which leaves only one RCP running at power. RPS will trip if no RCPs are running in a loop when greater than 0% power.
(a) is incorrect because indications are of a sheared shaft which requires a manual reactor trip.
(c) is incorrect because a loss of seal cooling alone will not cause a reactor trip.
(d) is incorrect because a loss of "D" RCP would result in one RCP in each loop with reactor power <55% - no automatic reactor trip will result.

The plant is operating at 100% power near EOL.
During pre-outage scaffolding construction in Lower North Piping Room (LNPR),
the instrument air line to the following valves has been severed:
- CV-1235, Pressurizer Level Control
- CV-1222, Letdown Orifice Block
- CV-1223, Letdown Orifice Bypass
- CV-1207, RCP Seals Total Injection Flow With no operator action, which of the following describes the expected system response?
- a. Pressurizer level will rise continuously.
- b. Pressurizer level will rise to a higher steady state value.
- c. Pressurizer level will drop continuously.
- d. Pressurizer level will drop to a lower steady state value.
Answer:
- a. Pressurizer level will rise continuously.
Notes:
CV-1235 and CV-1222 fail as-is on a loss of instrument air.
CV-1223 fails closed and CV-1207 fails open on a loss of instrument air.
This will result in lower letdown flow and higher seal injection flow resulting in PZR level to continuously rise.
Thus "a" is the correct answer, all other answers are incorrect and could be chosen if candidate fails to recall failure modes.

Answer:
- a. Control rods move inward, feedwater flows go up.
Notes:
The mismatch alarm disables the SASS module automatic operation. When NI-6 fails to 125% power, ICS will see NI-6 as the input power. ICS will generate an error to drive rods in. AT the same time a cross-limit is generated to keep feedwater balanced with reactor power. Feedwater will go up. Therefore, "b", "c", and "d" are incorrect.

Notes:
Change.
Answer "c" is the correct response, the indications given are that of "A" RB Spray pump suction vortexing on the RB sump.
Answer "a" is incorrect, Spray flow will still be too high to alleviate vortexing.
Answer "b" is incorrect, although damage could occur if conditions are maintained, throttling will correct problem and it is desirable to maintain RB Spray flow.
Answer "d" is incorrect, throttling LPI flow to the minimum value could lessen vortexing, no procedural guidance of this kind exists. At one time it was discussed to throttle both RB Spray and LPI flow after swap to RB Suction but only Spray flow is throttled.

Answer:
- c. Levels may not be sufficient to reflood the vessel following a LOCA.
Notes:
(a.) is incorrect. This would be the case if either level were out of spec high, however, the problem is the level on T-2B is out of spec low.
(b.) & (d.) are incorrect. N2 pressures are within the Tech Spec limits which ensure that the pressure meets the design bases for the system.
(c.) is correct. T-2B level is below the Tech Spec limit of 12.6 feet which is based on having sufficient volume to refill the core for adequate core cooling purposes.

Why did this occur?
- a. 4160v bus transfer from Unit Aux to S/U #1
- b. RCS pressure is greater than heater setpoint
- c. PZR level decreased due to cooldown
- d. PZR swelled, squeezing the steam bubble Answer:
- c. PZR level decreased due to cooldown Notes:
"C" is correct due to cooldown from +100 psig bias to TBV setpoint not being applied causing RCS to shrink, resulting in PZR outsurge which could drop PZR level below the heater cutout setpoint of 55 inches.
"A" is incorrect, this has no effect on heater power.
"B" is incorrect because pressure will be decreasing due to cooldown.
"D" is incorrect because cooldown will cause a PZR outsurge, not an insurge.

Answer:
- c. The reactor building purge outlets should be opened first.
Notes:
"c" is correct, with RB pressure positive, the RB purge outlet valves are opened first to prevent reverse flow through the RB purge exhaust filters. Reverse flow through these filters can damage them.
"a" is incorrect, this will cause reverse flow through the purge exhaust filters.
"b" is incorrect, this is difficult to do and provides no assurance that reverse flow will not occur.
"d" incorrect, this is used to lower pressure in the RB at power but is not required prior to initiating purge during cold shutdown.

During 3 circulating water pump operation, the 'A' circ water pump trips.
The standby circ pump was started and plant conditions have stabilized.
It is noticed that the condenser waterbox discharge temperature is 10 degrees higher and condenser vacuum has dropped.
Which of the following is the cause of this condition?
- a. The stopping and starting of a circ pump caused fouling to be removed from the tube sheet promoting better heat transfer capabilities.
- b. The discharge valve on the tripped pump did not go completely closed and circulating water is short cycling.
- c. The debris on the bar grates of the circulating water bays was stirred up during the circ pump swap causing reduced flow.
- d. These are normal conditions following rotation of circulating pumps and temperatures will return to normal within 30 minutes.
Answer:
- b. The discharge valve on the tripped pump did not go completely closed and circulating water is short cycling.
Notes:
(a.) is incorrect. Although some fouling can be removed during pump rotations, it should not result in a 10 degree change in waterbox discharge temperature.
(b.) is correct. The discharge valve on an idle pump can allow a significant amount of backflow from the operating pumps if it is not closed completely.
(c.) is incorrect. This condition is normal for a circ pump swap and may contribute to waterbox fouling, however, the service water system would be affected by this condition as well.
(d.) is incorrect. There should not be such a large temperature difference even if only 3 CW pumps are in service.

Answer "a" is correct, the inhibit switch is used when one of the two detector strings is malfunctioning and it is desired to prevent an automatic actuation caused by a single failure of the remaining detector string.
Answers "b" and "d" are incorrect since the Inhibit switch does not have anything to do with any manual actuations.
Answer "c" is incorrect, the Inhibit switch works with the actuation circuit only and not with detection alarms.

- Maintenance is planned on the Non-Nuclear ICW loop.
- The Non-Nuclear ICW Pump P-33A was secured on the previous shift in preparation for tagging out the Non-Nuclear ICW loop.
- Nuclear ICW is in service supplying Spent Fuel Cooling.
- The WCO reports the Dirty Waste Drain Tank T-20 is rising and he doesnt know why.
Which of the following could be the cause of this condition?
- a. The ICW Surge Tanks common drains are cross connected.
- b. The ICW Discharge Cross-connect valves are leaking by.
- c. A Spent Fuel Filter relief valve is leaking by.
- d. The "A" Decay Heat Cooler has a leak.
Answer:
- b. The ICW Discharge Cross-connect valves are leaking by.
Notes:
Answer "b" is correct, discharge cross-connect valve leakage would result in overflow of the idle ICW surge tank. Therefore the ICW Surge Tanks are procedurally cross-connected to prevent the idle loop surge tank from overflowing. Overflow would be directed to the floor drains at the surge tanks, which drain to the T-20s.
Answer "a" is incorrect since the Surge Tanks are cross connected to prevent idle loop surge tank overflow.
Answer "c" is incorrect because the Spent Fuel Filter reliefs drain to the ABEDT.
Answer "d" is incorrect because the DH vaults drain to the AB Sump via manual isolations which are normally closed.

Plant operating at 100% power.
The instrument air line to Turbine Bypass Valve (CV-6688) valve operator is severed, causing the instrument air accumulator for CV-6888 to depressurize.
What effect will this have on CV-6688 operation?

- d. CV-6688 will only respond to MANUAL control signals.
Answer:
- a. CV-6688 will go OPEN due to system pressure.
Notes:
On a loss of instrument the accumulator for CV-6688 will maintain the valve closed for a period of time. But the given condition of a failure of the instrument air line to the valve operator will result in a loss of accumulator pressure. At the given power level, the valve will be forced open by steam pressure. Therefore the only correct response is (a).

During a loss of offsite power with a SG tube leak, the A2 bus is re-energized from the A4 bus. The A4 bus is supplied by #2 EDG.
What is the key reason for this action?
- a. To start P-7B EFW pump and secure P-7A.
- b. To restart Circ. Water and re-establish condenser vacuum.
- c. To allow operation of the Aux Feedwater pump (P-75).
- d. To re-establish Instrument Air and ICW cooling.
Answer:
- d. To re-establish Instrument Air and ICW cooling.
Notes:
The strategy here, regardless of the tube leak, is to re-establish Instrument Air and ICW and ease complications of this transient by restoring RCP seal cooling and Letdown. Thus, answer [d] is correct.
[a] is a good idea during a tube leak but P-7B is powered from A3, making it unnecessary to energize A2.
[b] is also a good idea but procedural actions eliminate the need to re-establish condenser vacuum.
[c] incorrect, although the Aux Feedwater Pump is powered from A2, it is not the basis for performing this action.

Answer:
- d. Verify containment isolation valves are in position marked with black tape background.
Notes:
(d) is the correct response. A black tape background identifies the proper actuation position of ES components. (a) is incorrect because not all containment penetration valves will be closed, (b) is incorrect because there is no chart of valve positions in RT-10, (d) is incorrect because color coding of panel does not identify proper actuation position.

- c. HPI Cooldown
- d. Stay in Tube Rupture Answer:
- c. HPI Cooldown Notes:
"a" is incorrect, Loss of Subcooling Margin is entered only if a Loss of SCM occurred prior to entry into the Tube Rupture EOP and conditions do not indicate a Loss of SCM. "b" is incorrect, ESAS is not entered from Tube Rupture. The ESAS would have had to occur prior to the Tube Rupture for entry into ESAS. "c" is correct, neither OTSGs is suitable for heat removal since both are ruptured and have been isolated. BWST level <23 feet with these conditions is an entry condition for 1202.011, HPI Cooldown. "d" is incorrect since 1202.006, Tube Rupture, provides guidance to transition to HPI Cooldown for the given conditions.
