2) Cooling to the RCP bearing oil coolers has been:

A. 1) maintained throughout the event

2) maintained throughout the event B. 1) isolated Key

2) maintained throughout the event C. 1) isolated

2) isolated sw D. 1) maintained throughout the event

2) isolated er Proposed Answer: A. 1) maintained throughout the event

2) maintained throughout the event Explanation:

An A. Correct. Phase A isolates seal return from the #1 RCP seals to the VCT and directs it to the PRT, however, as long as FCV-128 is still open (is not closed by phase A), backpressure will continue to supply charging to the seals. NOTE, in the EOPs, the crew is instructed to "maintain 8 to 13 gpm to RCP seals". Bearing oil coolers lose CCW cooling if Phase B 62 actuates, (22 psig) Note, if Phase B actuates, then cooling would be lost to both the thermal barrier and the oil coolers..

B. Incorrect. Plausible if its assumed that the seal cooling is lost when phase A actuates (containment pressure of 3 psig), this does stop charging injection, thru FCV-128 via the L1 normal flowpath however the thermal barrier is still cooled by CCW Cooling to the motor oil coolers is maintained because containment pressure remained less than the Phase B setpoint.

C. Incorrect. Plausible if either its assumed that containment pressure rose above the Phase B setpoint or its thought both are lost at the Phase A setpoint of 3 psig.

D. Incorrect. Plausible - cooling is maintained to the #1 seal and its thought that motor oil coolers lose cooling at Phase A or Phase B setpoint was exceeded but that cooling is maintained to the #1 seal solely by RCS flowing past the seal.

1) According to a CAUTION in OP A-2:I, if RCS pressure is allowed to lower to less than VCT pressure, a potential consequence is that a _________ bubble will collect in the reactor vessel er

2) Removal of this bubble will require ___________.

A. 1) hard 2) raising RCS pressure B. 1) hard An 2) venting C. 1) potentially explosive 2) raising RCS pressure D. 1) potentially explosive 2) venting 62 Proposed Answer: B. 1) hard 2) venting Explanation:

NOTE, normal at power gas supply to the VCT is hydrogen which is explosive. When shutdown, L1 a blanket of nitrogen, not explosive, is put on the VCT. The candidate must know what the shutdown gas in the VCT is, what type of bubble could form and then how its removed.

A. Incorrect. the caution states that if RCS pressure drops below VCT pressure, a "hard bubble of VCT gases" could collect in the vessel head or pressurizer. Venting would be required.

Raising pressure could be believed in the case that its believed a hard bubble may be removed this way (method of removal for a saturated bubble) OR its believed that raising pressure will force the gas back the VCT B. Correct. Nitrogen is the gas in the VCT when shutdown and could migrate to the vessel head or pressurizer. Removal of any hard bubble is to vent the head (or pressurizer).

C. Incorrect. Normal, at power, gas in the VCT is hydrogen which is potentially explosive, nitrogen is not. If it assumed nitrogen is also explosive, this is feasible. Venting would be required. Raising pressure could be believed in the case that its believed a hard bubble may be removed this way (method of removal for a saturated bubble) OR its believed that DCPP L162 Exam Rev 1

raising pressure will force the gas back the VCT D. Incorrect. Normal gas in the VCT is hydrogen which is potentially explosive, nitrogen is not. If it assumed nitrogen is also explosive, this is feasible. Venting is the method of removal..

Rating 4.5 Question 03 Following a design basis LOCA, loss of which of the following would meet the entry conditions for EOP ECA-1.1, Loss of Emergency Coolant Recirculation?

Loss of:

A. both RHR pumps B. both Charging pumps and a RHR pump C. both SI pumps and both Charging pumps D. one train of ECCS pumps (RHR, SI and ECCS CCP)

Key Proposed Answer: A. both RHR pumps Explanation:

swer Note: RO and SRO objective to know major actions and entry conditions for EOPs. Question is a simple entry condition question - appropriate for RO (on SRO flowchart, "Can the question be answered solely by knowing the purpose, overall sequence of events, or overall mitigative strategy of a procedure?" would be answered "yes" or RO knowledge.

An A. Correct. ECA-1.1 is entered when the plant cannot establish at least one train of recirculation with an RHR pump and the containment sump. Without an RHR pump, the SI or charging pumps would not have a suction source.

B. Incorrect. Loss of the SI pumps would degrade recirculation but as long as there is an RHR pump, there is a recirculation flowpath.

C. Incorrect. Charging pumps are the major contributors to degrading conditions leading to 62 inadequate core cooling if there is a small break but an absence of charging pumps does not meet the entry conditions for ECA-1.1, only the lack of an RHR pump.

D. Incorrect. RHR pump (or lack of a flowpath) is the only condition that causes entry into ECA-1.1. In E-1.3 step 12, part of the step is to check for NO flow from any of the flow L1 indicators, RHR, SI, charging and if there is no flow on all of them (due to the first part, no RHR pump), then the RNO is go to ECA-1.1. If this step is remembered incorrectly, this would seem to be the answer.

A. Incorrect. The pumps are stopped and the pump discharge valves are closed when aligning CS from RHR. However, it is not interlocked with the operation of 9003 A/B. Plausible to believe the normal suction valve(s) must be closed to open the flowpath from RHR.

B. Correct. In order to open 9003 A or B, the associated containment sump suction valve, 8982 A or B must be open and EITHER 8701 or 8702 must be closed. Closing 8701 provides an input to the interlock to open the valve.

C. Incorrect. 8809A does not impact the operation of the valve, but is operated (closed) just prior to opening 9003A in E-1.3.

D. Incorrect. 8804A (and 8804B) are opened to provide suction to charging and SI pumps.

Because RHR is being aligned to Cont Spray, plausible that 8804A must be closed to ensure an adequate suction path to the containment spray pumps.

swer The auto actions to meet the KA are the lifting of the relief valve at 600 psig, which discharges to the PRT and the pressure at which the rupture disc fails of 100 psig. Normal level in the PRT is approximately 85%. Normal pressure is approximately 3 psig.

An A. Incorrect. Closing of 8152 will cause relief valve 8117 at 600 psig. 450 psig is the setpoint for the RHR to PRT relief valve. In 3 minutes pressure is only about 20 psig. Plausible if the 85% level is confused as 85 psig.

B. Incorrect. Closing of 8152 will cause relief valve 8117 at 600 psig. In 3 minutes pressure is only about 20 psig. Plausible if the 85% level is confused as 85 psig..

C. Incorrect. Closing of 8152 will cause relief valve 8117 at 600 psig. 450 psig is the setpoint 62 for the RHR to PRT relief valve.

D. Correct. Closing of 8152 will cause relief valve 8117 at 600 psig. The rupture disc setpoint is 100 psig. Normal pressure is approximately 3 psig, so it would take about 19 minutes for pressure to rise to the setpoint L1 Technical

2) lowers Key C. 1) lowers 2) lowers D. 1) lowers 2) rises swer Proposed Answer: D. 1) lowers 2) rises Explanation:

A. Incorrect CCW valve TCV-130 fails open on of instrument air. Failing open causes CCW flow through the heat exchanger to increase and letdown temperature to decrease (not rise)

Plausible - power will rise.

An B. Incorrect. Plausible because this would be correct if TCV-130 failed closed.

C. Incorrect. Letdown temperature will lower but the effect is to remove boron. Boron is released and power rises. Plausible if the effect of lowering letdown temperature is reversed (boron is released - lowering power)

D. Correct. TCV-130 fails open. This will lower letdown temperature. At full power, MTC is 62 negative, lowering letdown temperature removes boron from letdown, which is a positive reactivity effect and power will rise.

PCV-474 is prevented from opening due to the low pressure interlock from PT-474. Plausible if its not known that PT-474 is the low pressure interlock channel for the control portion of the PORV circuitry which controls the PORV opening from the "second highest pressure" control circuitry. Also, logical to assume the interlock channel would be a different channel (as is the situation for PCV-455C)

An B. Incorrect. PCV-455C is prevented due to the failure of PT-474. Plausible because there is only one PORV that will open, but its PCV-456.

C. Incorrect. Both PCV-455C and PCV-474 will not open. PCV-474 is independently controlled by its associated channel, PT-474. PCV-455C is prevented from opening due to low pressure interlock met due to the failed PT-474 less than 2185 psig. Plausible that PT-62 455C, with PCV-456 are unaffected by PT-474.

D. Correct. 2 PORVs are prevented from opening but its PCV-455C and PCV-474. PCV-456 will still operate.

2) stop and restart when sequenced on to their respective Emergency Diesel Generator DCPP L162 Exam Rev 0

Proposed Answer: B. 1) NOT automatically

2) remain running without interruption Explanation:

Tests what the operator would see in the Control Room (operational validity) when RCS pressure is less than 1915 psig and an accident occurs (steam break). Additionally, the response of the AFW pumps when the SI occurs (do they or dont they stop and sequence on when SI occurs).

A. Incorrect.SI on low RCS pressure is blocked below P-11 (1915 psig) (PK08-06 LIT).

Plausible if P-11 is thought to only affect RCS pressure SI. Also, SI would automatically actuate if the break was inside containment and pressure rises to greater than 3 psig.

B. Correct. SI will not actuate automatically, however, the AFW are not stripped and then restarted. They would be if there was also a transfer to diesel, but if startup is available, no load stripping occurs.

C. Incorrect. This would be the response at power and the AFW pumps were not running and startup was not available.

Ke D. Incorrect, P-11 blocks Low Pressurizer pressure AND low steamline pressure SI (PK08-16 and 17 LIT). The AFW are not stripped. Plausible because for most SI actuations which y

cause a reactor trip and bus transfer from 500 kV to either startup or diesel, the AFW pumps would be sequenced. In this case, already on startup, no bus stripping occurs and the pumps will remain running.

Turbine Driven AFW pump motor operated valves LCV 106, 107, 108, and 109 will be deenergized if 480V bus G is lost and personnel will have to be dispatched locally to control L1 AFW flow. .

A. Incorrect. DC bus 22 powers FCV-95 and it will not open. Additionally, bus G will be de-energized and the LCVs, which are powered from 480 VAC bus G will not have power.

Plausible because valves have different fail position, and it could be thought FCV-95 fails open (to ensure start of the AFW pump) or because the LCVs are MOVs the loss of DC is not obvious that it prevents valve operation..

B. Incorrect. FCV-95 fails "as is" on a loss of DC. Plausible because many DC components fail open/closed on a loss of power.

C. Incorrect. FCV-95 fails "as is" on a loss of DC. Plausible because many DC components fail open/closed on a loss of power.

D. Correct. FCV-95 has lost DC power and fails as-is, it must be opened locally. The LCVs are also not powered (are in the full open position) due to the loss of the 480 VAC bus and must be operated locally.

L1 The Fuel Handling Ventilation system is:

A. properly aligned for Iodine removal.

B. not properly aligned because there is a supply fan is running.

C. not properly aligned because exhaust fan E-6 should not be running and E-4 or E-5 should be running.

D. not properly aligned because in addition to exhaust fan E-6 running, E-5 should also be running.

DCPP L162 Exam Rev 0

Proposed Answer: A. properly aligned for Iodine removal Explanation:

A. Correct. The proper alignment is one supply fan and either exhaust fan E-5 or E-6. The alignment shown is correct.

B. Incorrect. A supply fan should be running. The capacity of the exhaust fans is greater than the supply fans, so the supply fans do not need to trip to maintain a negative pressure in the FHB. Additionally, the Aux Bldg ventilation stops supply fans in the "safeguards" mode.

C. Incorrect. E-4 is the fan that is not used for Iodine removal. Either E-5 or E-6, depending on the which is selected by a switch on VB4. Plausible because it may not be known that one of the fans isn't used but whether its E-4 or E-6 is not.

D. Incorrect. If it's thought that ventilation that the additional exhaust fan must run to ensure the proper pressure is maintained in the FHB with the supply fan running.

A Pressurizer PORV is partially open.

The crew is performing the ECCS flow reduction actions of E-1.2, Post LOCA Cooldown and Depressurization

One Charging and both SI pumps are running

The RHR pumps are secured

Conditions are met for securing one of the running SI pumps y

When the SI pump is secured, RCS pressure begins to decrease.Ke According to a Note prior to the step in E-1.2, what action should be taken?

A. Immediately restart the SI pump.

B. Restart an RHR pump in the SI mode.

er sw C. Proceed on to securing the second SI pump.

D. Wait for RCS pressure to stabilize or increase before taking action to stop the second SI pump.

Explanation:

An Answer: D. Wait for RCS pressure to stabilize or increase before taking action to stop the second SI pump.

From E-1.2 background: After an SI pump is stopped, RCS pressure may decrease to a new equilibrium value where the reduced SI flow again matches leakage from the RCS. The criteria 62 for stopping the next SI pump has been calculated assuming steady-state conditions. Hence, to ensure that these criteria are appropriate, RCS pressure and subcooling should be allowed to stabilize or increase before additional SI pumps are stopped.

A. Incorrect, note states pressure should be allowed to stabilize or increase. Plausible because L1 there are conditions that require restarting ECCS pumps, such as loss of subcooling on the foldout page.

B. Incorrect, RHR pumps are restarted if subcooling is low when checking reduction criteria or if Tave is less than 350F prior to stopping an SI pump .

C. Incorrect, a period of time should pass to ensure RCS pressure will stabilize. Plausible if its thought this is the normal response and securing the next pump will be done if pressure stabilizes.

D. Correct - E-1.2 NOTE - After stopping any ECCS Pp, RCS Pressure should be allowed to stabilize or increase before stopping another ECCS Pp.

sw A. Incorrect. A small break is the likely failure, however, CETCs are the indication. RVLIS is used in conjunction with CETCs to indicate challenges to core cooling but RVLIS level can be below the top of the core and not have an inadequate core cooling issue.

B. Correct. The small break is the probable break to lead to a challenge to core cooling.

CETCs greater than 1200°F indicate inadequate core cooling.

An C. Incorrect. Large breaks are plausible because of the potential for the core to become partially uncovered for a short period of time, however, accumulators will refill the core and will not cause ICC. RVLIS by itself does not indicate a challenge to core cooling D. Incorrect. Large breaks cause a potential for the core to become partially uncovered for a short period of time, however, accumulators will refill the core and will not cause ICC.

CETCs above 1200°F indicate inadequate core cooling.

the RCS sw If a loss of all AC Vital power has occurred, the RCPs are off (loss of RC Flow) and heat removal is via natural circulation. Natural circulation is enhanced by maintaining sufficient steam generator level.

An NOTE: Obj to know basis of EOP steps is RO and SRO knowledge. Also, RO expected from multiple EOPs that adequate heat sink is 15% in one steam generator.

A. Incorrect. The step requires at least one steam generator greater than 15%. The pressure lowering uncontrollably is the basis for maintaining level above 15% in E-3, Steam 62 Generator Tube Rupture.

B. Incorrect. The step requires at least one steam generator greater than 15%. Reason is correct.

C. Incorrect. Only one steam generator is required. The pressure lowering uncontrollably is L1 the basis for maintaining level above 15% in E-3, Steam Generator Tube Rupture D. Correct. One steam generator is required. Per the background document, The analysis basis for ECA-0.0 requires that the level in at least one intact steam generator (SG) be above the top of the SG U-tubes to ensure that sufficient heat transfer capability exists to remove heat from the RCS via either natural circulation or reflux boiling after the RCS saturates which is accomplished by maintaining level above 15%.

The operator stops the running charging pump when it was showing signs of cavitation. The operator reports VCT outlet valves 112B and 112C are open and RWST outlet valves 8805A and 8805B are closed.

y When checking VCT level, which of the following VCT level channel failures would be expected to have caused the observed indications?

A. LT-112 failed LOW B. LT-112 failed HIGH Ke C. LT-114 failed LOW D. LT-114 failed HIGH er Explanation: sw Proposed Answer: B. LT-112 failed HIGH Question addresses a "loss of makeup" (charging) from the perspective of the VCT makeup failure that leads to a loss of charging by causing VCT to drain and there is no swapover to An RWST. Ultimately, there could be a loss of all charging due to gas intrusion from the VCT to the suction of the charging pumps.

A. Incorrect. Plausible if failure is misconstrued. LT-112 LOW would initiate continuous makeup and the VCT fills and diverts. Charging and letdown unaffected.

B. Correct. Auto makeup is lost. VCT level will decrease. No auto swapover to the RWST, at 5%

62 will occur (requires both channels, LT112 and LT114). VCT empties, charging flow decreases to 0 gpm. Pressurizer level decreases, letdown isolates and heaters de-energize.

C. Incorrect. VCT level would be maintained by LT112. If level on LT-112 were to also lower to 5%, auto swapover to RWST. Charging flow would be maintained. Plausible if the functions L1 for LT112 are assumed for LT114.

D. Incorrect. This fully opens LCV-112A. VCT level decreases to 14%, auto makeup from LT-112, makeup is greater than letdown. Plausible if its thought auto makeup is defeated (as for LT112).

EOP E-1.3 includes operator actions to limit the heat loads during post-An LOCA cold-leg recirculation if less than two ASW pumps and two CCW heat exchangers are in Service (a loss of one train).

A. Incorrect. With a single train of CCW in service, its plausible the student could focus on the single CCW train and believe runout is a possibility. The problem is due to the lack of cooling (from ASW), CCW heat removal is reduced to the point that if loads are not restricted, design temperature could be exceeded.

62 B. Incorrect. The system is designed for one pump to supply both CCW trains during normal operation without runout. Plausible because, if one train is supplying both trains of CCW, then its possible to think the loads could cause the only running ASW pump to approach runout.

L1C. Incorrect. Temperature remains less than saturation. Plausible because if two trains of CCW were put into service with only one train of ASW, temperature will rise.

D. Correct. The heat load of all the loads on the CCW with only one ASW train could cause the system to not be able to meet its purpose to remove heat from the CCW system and the CCW system could exceed its design temperature.

Explanation:Answer:

sw Question addresses the condition for entry into ECA-1.1 and the remedial action to take IAW ECA-1.1. Major actions of EOPs and exit conditions are identified in the lesson material as RO knowledge.

An The following are the major actions for ECA-1.1:

Continue attempts to restore emergency coolant recirculation

Raise/conserve RWST level

Initiate cooldown to cold shutdown

Depressurize the RCS to minimize subcooling

Try to add make-up to the RCS from alternate sources, 62

Depressurize the S/Gs to cooldown and depressurize the RCS

Maintain RCS heat removal A. Incorrect. RCS pressure is the parameter checked. ECA-1.1 does not attempt to isolate a LOCA, regardless of location. Focus is to conserve RWST and attempt to restore L1 emergency coolant recirc.

B. Incorrect. RCS pressure is the parameter checked. ECA-1.1 does not attempt to isolate a LOCA, regardless of location. Focus is to conserve RWST and attempt to restore emergency coolant recirc. Pressurizer level is plausible because it is a parameter that should be restored but pressure is the more immediate and therefore, indication checked.

C. Correct. RCS pressure should respond by rising if the leak isolation is successful, otherwise, the transition to ECA-1.1 is made to take actions that include refilling and conserving RWST.

D. Incorrect. Action is correct, but the parameter is RCS pressure, not pressurizer level.

An A. Incorrect. Power cabinet failure would have stopped all rods in the bank from moving. The rod is aligned to the bank, therefore, its lift coil is left connected, the rest of the lift coils are opened. Plausible because the power cabinet failure would stop rod motion and if its thought the bank is aligned to the rod, not vice versa.

B. Incorrect. Action is correct, but a power cabinet urgent failure will stop all rods.

62 C. Incorrect. A blown fuse will not generate an urgent failure because the bank is moving, but will stop an individual rod from moving. Action is not to align bank to the rod but vice versa.

D. Correct. The lift coil fuse failure would cause the rod to stop moving. The rod does not L1 drop because the stationary or movable gripper is always energized.

A. Incorrect. P-14 closes all the valves listed. Because RCS temperature is above 554°F, its plausible to believe the Main Feedwater Reg and bypass are still open (closed by SI, P-14 or Low RCS Tave/P-4).

B. Incorrect. All 5 safeties will be open above 1115 psig. Plausible - all the valves will be closed and the safety setpoints may not be known.

C. Incorrect. All the valves will be closed. Plausible - all 5 safeties will be open.

DCPP L162 Exam Rev 0

D. Correct. All the valves are closed by P-14 and the highest setpoint for the safeties is 1115 psig, therefore, for the current pressure, all will be open.

Question 64 Unit 1 has experienced a large break Loss of Coolant Accident.

The operator reports that containment recirc sump level is 99 feet. The STA reports that the Critical Safety Function Status tree for Containment Integrity is MAGENTA due to the sump level.

The crew will enter FR-Z.2, Response to Containment Flooding:

y Ke A. to determine what additional water source is filling containment above design level.

B. but immediately exit it once it is verified that this is approximately the expected level when the RWST reaches the transfer to cold leg recirc setpoint.

er C. to check for indications of a faulted steam generator.

D. but immediately exit it once it is verified that this is approximately the expected level when sw the RWST reaches the level for containment spray termination.

Proposed Answer: A. to determine what additional water source is filling containment above Explanation:

An design level.

A. Correct. FRZ-2 step 1 directs operators to exit Flooding in Containment for recirc sump levels less than 95.75 feet. A level of 99 feet is much higher than what is expected for a LCOA. The Response to Containment Flooding Background Document, FRZ-2, states, The maximum level of water in the containment following a major accident generally is based 62 upon the entire water contents of the reactor coolant system, refueling water storage tank, condensate storage tank, and SI accumulators.

B. Incorrect. The status tree may just be magenta during a LOCA but will not reach 99 feet.

L1 This is the water volume from the RCS, RWST, CST, and 4 SI Accumulators. This approximates the maximum water volume introduced following a LOCA plus a steamline or feedline break inside of containment.

C. Incorrect. The correct level per step 1 of FRZ-2 is 95.75 feet. The maximum level of water in the containment following a major accident generally is based upon the entire water contents of the reactor coolant system, refueling water storage tank, condensate storage tank, and SI accumulators. This is the volume of LOCA plus a steamline or feedline break.

D. Incorrect. The status tree may just be magenta during a LOCA but will not reach 99 feet.

The correct level per step 1of FRZ-2 is 95.75 feet.

Post LOCA Cooldown and Depressurization. QUESION DELETED. SEE EXAM REPORT 2018-301 FOR DETAILS L1A. Incorrect. The leak size is such that E-1.2 will be used to cooldown the RCS and perform the step wise ECCS flow reduction. E-1 is for LOCAs that reduce RCS pressure to less than RHR injection pressure, 300 psig.

B. Correct. Diverse indications of SG activity should convince the operators that RM-74 has failed high. There is no valid indication of activity in any SG. E-0 diagnostic should lead to E-1. With a leak rate of only 150 gpm, the next procedure transition at Step 13 should be E-1.2.

C. Incorrect. There is not a valid indication of a tube rupture. E-0 transition is "valid" alarm.

Plausible, this would be correct if there was a tube rupture and RCS leakage.

D. Incorrect. No valid indication of a tube rupture. Plausible, this is the normal flowpath for a tube rupture.

er A. Both the 230 kV and 500 kV offsite power sources remain OPERABLE.

B. The 230 kV source remains OPERABLE, the 500 kV source is inoperable.

C. The 230 kV source is inoperable, the 500 kV source remains OPERABLE.

An D. Both the 230 kV and 500 kV offsite power sources are inoperable.

Proposed Answer: C. The 230 kV source is inoperable, the 500 kV source remains OPERABLE.

Explanation:

62 The SFM is responsible for Tech Spec entries due to inoperable electrical sources or equipment.

If there is a question of operability, SR 3.8.1.1 is performed by completing section 17 of STP I-1C and OP J-2:VIII.

Working thru the attachments of OP J-2:VIII:

L1 For DCPP/Mesa configuration, table 1, 2 DCPP caps - 2 and 2 caps for Mesa is line 2-3.

Minimum DCPP normal transfer limits - voltage 230 kV , load 400 MW. For Level C, 229 and 415 respectively Per attachment 2 (left to right) - YES for first block (230 required but currently 232), NO for next block (Normal transfer load limit is 400 and currently at 420 MW). Configuration (at power) 3 for next block, Comp actions 1 or 3 complete - YES (Cond Booster pumps auto start blocked), YES for next block (Level C voltage greater than 229), Load less than Level C - NO, load is 420, max is 415 mw. Startup is inoperable.

A. Incorrect. There are two 230 kV lines and three 500 kV lines. According to the bases for LCO 3.8.1, the sources are OPERABLE if one 230 kV (with conditions) and two 500 kV lines satisfy the LCO. A loss of one line of each does not affect operability providing DCPP L162 Exam Rev 1

voltage and load for the existing 230 kV lineup is acceptable. For the current lineup, the minimum voltage is 229 kV. Working thru the attachments, show that this is the minimum even if comp measures are in place. NOTE: The 12 kV cutouts would need to be taken to cutout, the condensate booster pump cutouts are cutout at power. For the current conditions, voltage is too low, the 230 kV is inoperable. 500 kV voltage has not changed and because a loss of a single line does not make the system inoperable, the 500 kV system remains OPERABLE.

B. Incorrect. A single line loss does not make the 500 kV inoperable as long as voltage is acceptable, if its unchanged from the initial conditions, then the 500 kV is still OPERABLE. Plausible because loss of one line would seem likely to cause at least one offsite source inoperable. Additionally, using J-2:VIII, 230 kV is inoperable.

C. Correct. A single line loss does not make 500 kV inoperable. Additionally, for the current configuration, 230 kV is inoperable. See explanation above.

References:

LCO 3.8.1, OIM J-1-1 and OP J-2:VIII Ke D. Incorrect. A single line loss does not make 500 kV inoperable. Plausible because 230 kV is inoperable and loss of a line would seem plausible to be inoperable.

er D. 1) will NOT

2) when reactor power is less than 10%

Proposed Answer: D.

1) 2)

will NOT An when reactor power is less than 10%

Explanation:

Candidate must know that due to the loss of compensating voltage, the channel will not lower 62 sufficiently to provide the necessary overlap and cause P6 to automatically energize the Source Range (requires two IR channels less than 10-10 amps. Also, from LCO 3.3.1 that the action is to either lower power to less than P-6 or raise power to greater than 10% with one channel inoperable. Coming down, the LCO will not be entered until power is less than 10&% (SRO).

L1A. Incorrect. For many instrument failures, the LCO immediately applies, such as for a failed Power Range channel. Also, the necessary overlap to energize the Source Range would be met if the N36 channel was over compensated (it would read lower and get to the setpoint sooner).

B. Incorrect. The effect of undercompensation is to make the channel read higher, preventing auto energizing of the source range channels. Second part is correct..

C. Incorrect. First part is correct, Second part plausible, for many instrument failures, a shutdown is required, however the LCO for IR channels apply when less than 10%

D. Correct. P6 will not energize the source range channels and the LCO does not apply until less than 10% power.

er Proposed Answer: D. reactor vessel flange and a minimum decay time of 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months prior to fuel handling.

Explanation:

An A. Incorrect. Plausible - There is a requirement for the SFP for water level that maintains at least 8 feet above the top of the fuel for shielding (not fuel accident). The bases for the RHR in service LCO states the reason is that if the reactor coolant temperature is not maintained below 200°F, boiling of the reactor coolant could result. This could lead to a loss of coolant in the reactor vessel. Additionally, boiling of the reactor coolant could lead to boron plating out on components near the areas of the boiling activity.The loss of reactor 62 coolant and the reduction of boron concentration in the reactor coolant would eventually challenge the integrity of the fuel cladding, which is a fission product barrier. One train of the RHR System is required to be operational in MODE 6, with the water level 23 ft above the top of the reactor vessel flange, to prevent this challenge.

L1B. Incorrect. The requirement is water over the reactor vessel flange, not the top of the fuel, the decay time of 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months is correct.

C. Incorrect. The level is correct. The RHR in service is to prevent boiling (which could reduce level).

D. Correct. Per the bases for LCO 3.9.7, with a minimum water level of 23 ft and a minimum decay time of 100 hours0.00116 days 0.0278 hours 1.653439e-4 weeks 3.805e-5 months prior to fuel handling, the analysis and test programs demonstrate that the iodine release due to a postulated fuel handling accident is adequately captured by the water and offsite doses are maintained well within allowable limits.

An Proposed Answer: A. 1) OP AP-14, Tank Ruptures 2) Shift Manager A. Correct. Low VCT pressure and level are indicative of a VCT rupture. The procedure to address it is OP AP-14. In AP-14, step 4 is to implement radiological emergency 62 procedures. First bullet is RB-2. RB-2 states the SM or the SEC or ED approves emergency exposures.

B. Incorrect. The procedure is AP-14, however, the SM approves emergency exposures prior to EOF/TSC activation. Plausible as the ED is in charge once the EOF is activated.

L1 C. Incorrect. PK11-21 could be in alarm for either loss of charging or tank rupture. Also, VCT level would lower for a large charging line leak (but pressure would not fall to 0 psig). The SEC approves emergency exposure.

D. Incorrect. The appropriate procedure is AP-14 not AP-17 and the SM approves emergency exposures.

D. To minimize the probability the valves will not fully close when the purge is secured, resulting in a breach of Containment integrity.

Explanation:

sw Proposed Answer: C. To minimize the probability of a LOCA occurring while the valves are open, limiting the offsite boundary doses.

er A. Incorrect. The NPDES covers releases to the environment, but releases to the ocean, not from Containment.

B. Incorrect. These butterfly valves are not fully open (limited to 50 degrees of travel), so its plausible that there is concern of wear.

An C. Correct .Containment purges rely on RM-44A and 44B to be OPERABLE. These are process rad monitors. Their operation is assumed to close the purge valves that are opened.

Per ECG 23.3, The purging time restriction is meant to minimize the probability of a LOCA while conducting purging operations and thereby limit offsite boundary doses.

D. Incorrect. The valves are limited in travel because these valves have not been qualified to close under accident conditions. Knowing that there is a concern with closing makes this 62 distractor plausible.

2) lower the cooldown rate C. 1) voided 2) raise the cooldown rate D. 1) voided An

2) lower the cooldown rate Proposed Answer: B. 1) stagnant 2) lower the cooldown rate Explanation:

62 A. Incorrect. The consequence is correct. However, the cooldown rate needs to be lowered.

Plausible because it could be that its believed increasing the cooldown will lower Tcold, which could lower the loop 21 Tcold, possibly restarting cooling in the loop.

B. Correct. Step 10 defines an inactive loop, is a loop that cannot be fed or steamed. Step 11 states that if hot legs in the inactive loop are not lowering at the same rate of the other L1 loops, it is stagnant. If its stagnant (Thot stable) then the RNO states to lower the cooldown rate (by a factor of 2).

C. Incorrect. Voids is plausible as this is also monitored during E-0.2 and is a potential consequence of too high a cooldown rate. Cooldown rate is lowered not raised.

D. Incorrect. Voids is plausible as this is also monitored during E-0.2 and is a potential consequence of too high a cooldown rate. Action to lower cooldown rate is correct.

62 Proposed Answer:

C. 1) Blowdown isolation valves, Outside Containment, FCV-151, 154, 157, and 160, close.

2) 10 CFR Part 20, Standards For Protection Against Radiation.

Explanation:

L1A. Incorrect. 10 CFR 20 is correct. The outside, not inside isolation valves close.

B. Incorrect. The state discharge permit is a limit the plant operates by but it is not what the ECG limit is based upon.

C. Correct. The outside isolation valves close and as stated in the bases for ECG 39.3, operable, releases may occur if the actions stated occur. ECG 39.3 bases states: The Alarm/Trip Setpoints for these instruments shall be calculated and adjusted in accordance with the methodology and parameters in the Offsite Dose Calculation procedure (CAP A-8) to ensure that the alarm/trip will occur prior to exceeding the limits of 10 CFR Part 20.

D. Incorrect. The outside isolation valves close but it is not the state permit the ECG is designed to meet but the 10 CFR part 20.

Additionally, there are notes and cautions that certain procedures are not performed .. (such as in E-1.3 which states FR 62 procedures are not addressed until aligned for cold leg recirc)

B. Incorrect. This is not the MAGENTA path forsubcriticality. A positive startup rate is the MAGENTA path and would then require stopping FR-C.2 because it would be a higher priority. Priority is Subcriticality, Core Cooling, Secondary Heat Sink, RCS Integrity, L1 Containment Intergrity and RCS Inventory (SCHPZI).

C. Correct. Both the RWST level and the Heat Sink RED path would require stopping the performance of C.2.
