Reference:
From LO21.SYS.SI1, PAGES 7 & 8 Revision 5/2/2011 The Emergency Core Cooling System is designed to remain functional after a Safe Shutdown Earthquake. The system is also protected from flooding, pipe whips, jet forces, and missiles. The system is designed to tolerate a single failure without a loss of its core protective functions. This failure is limited to an active failure during the short-term (injection) phase following a LOCA. When applied to the Emergency Core Cooling System, an active failure is defined as the failure of a powered component, such as a pump, power actuated valve, a component of the electrical supply system or instrumentation and control equipment, to act to accomplish its design functions. The worst-case single active failure would be the loss of one entire safeguards electrical train. The single failure is also limited to an active or passive failure during the long-term (recirculation) cooling phase. A passive failure is defined as the structural failure of a static component. When applied to a fluid system, this means a break in the pressure boundary resulting in abnormal leakage not exceeding 50 gpm for 30 minutes. Such leaks are consistent with limited cracks in pipes, sprung flanges, valve packing leaks or pump seal failures.

- A 3 Small Break Loss of Coolant Accident has occurred on Unit 1.
Which of the following describes the expected response of the Safety Injection Pump discharge flow as Reactor Coolant System pressure lowers from 1400 psig to 1200 psig?
Each Safety Injection Pump is initially discharging at...
A. 100 gpm and stable.
B. 0 gpm and stable.
C. 100 gpm and steadily rising to 250 gpm.
D. 0 gpm and steadily rising to 150 gpm.
Proposed Answer: C Explanation:
A. Incorrect. Plausible if thought that the Safety Injection Pump curves are vertical between 1400 and 1200 psig RCS pressure, however the flow is rising at a fairly substantial rate along this portion of the pump curve as the curve is more horizontal than vertical.
B. Incorrect. Plausible if thought that the Safety Injection Pump begin injecting into the RCS below 1200 psig, however, based on shutoff head and line losses the pumps begin injecting into the RCS at a pressure of approximately 1450 psig.
C. Correct. At 1400 psig RCS pressure (which equates to approximately 3500 ft of head, when RWST suction pressure and injection line losses are considered), each Safety Injection Pump would be injecting approximately 100 gpm with 45 gpm of recirculation flow. At 1200 psig RCS pressure (with similar assumptions as the 1400 psig condition) the pump would be injecting approximately 250 gpm based on the CPNPP Safety Injection Pumps.
D. Incorrect. Plausible if thought that the Safety Injection Pump begin injecting slightly below 1400 psig RCS pressure and flow would then increase at approximately the same rate as the actual pump head curve, however, based on shutoff head and line losses the pumps begin injecting into the RCS at a pressure of approximately 1450 psig.

C. Train A Safeguards Loop Isolation Valves close; Train B CCW Pump AUTO starts.
D. Train A Safeguards Loop Isolation Valves close; Train B CCW Pump remains in STANDBY.
Proposed Answer: D Explanation:
A. Incorrect. Plausible because it is a misconception that an empty CCW Surge Tank would trip Train A CCW Pump causing an AUTO start of the Train B CCW Pump. An empty CCW Surge Tank does not trip Train A CCW Pump, therefore, Train B CCW Pump does not auto start.
B. Incorrect. Plausible because it is a misconception that an empty CCW Surge Tank would trip Train A CCW Pump causing an AUTO start of the Train B CCW Pump. An empty CCW Surge Tank does not trip Train A CCW Pump, therefore, Train B CCW Pump remains in standby.
C. Incorrect. Plausible because it is a misconception that closure of Train A Safeguards Loop Isolation valves would lead to an AUTO start of Train B CCW Pump.
D. Correct. Train A Safeguards Loop Isolation Valves will close with CCW Surge Tank level at < 57%

- Unit 1 is operating at 50% power.
- PS-455F, PRZR PRESS CTRL CHAN SELECT, is in the 455/456 position.
- PT-456, PRZR PRESS CHAN II, fails high.
Assuming NO operator action, which of the following is the expected plant response?
A. A high pressure Reactor Trip occurs.
B. A low pressure Reactor Trip and Safety Injection occur.
C. Unit remains at power, with pressure being controlled at approximately 2185 psig.
D. Unit remains at power, with pressure being controlled at approximately 2335 psig.
Proposed Answer: C Explanation:
A. Incorrect. Plausible because pressure would increase with no operator action if PT-455 were to fail low and, if PORV 456 were to also fail, a high pressure Reactor Trip would occur, but with PT-456 failing high, pressure stabilizes around 2185 psig.
B. Incorrect. Plausible because a low pressure Reactor Trip and Safety Injection would occur with no operator action if PT-455 were to fail high, but with PT-456 failing high pressure stabilizes around 2185 psig.
C. Correct. With PT-456 failing high, PORV 456 opens and actual pressure begins lowering. The PRZR Spray Valves remain closed and the PRZR Heaters will energize as pressure sensed by PT-455 lowers, but the open PORV causes pressure to continue to lower. When PT-457 senses pressure below 2185 psig, the open interlock for PORV 456 is lost and the PORV closes. As pressure increases above 2185 psig due to the heaters, the open interlock for the PORV is restored and pressure will cycle around 2185 psig.
D. Incorrect. Plausible because pressure would increase and cycle around 2335 psig with no operator action if PT-455 were to fail low, but with PT-456 failing high pressure stabilizes around 2185 psig.

- Unit 2 is operating at 100% power.
- 125 VDC Bus 2ED1 de-energizes due to a fault on the bus.
Which of the following describes the effect of a loss of DC bus 2ED1?
A. Reactor will trip due to a shunt trip of Train A Reactor Trip Breaker.
B. Reactor will trip due to an undervoltage trip of Train A Reactor Trip Breaker.
C. A shunt trip signal will NOT be capable of opening Train A Reactor Trip Breaker.
D. An undervoltage trip signal will NOT be capable of opening Train A Reactor Trip Breaker.
Proposed Answer: C Explanation: With the Reactor Trip breakers being part of the Reactor Protection System the following plausibility statements are provided; A. Incorrect. Plausible because most actuations are de-energized to actuate, but the shunt trip requires that 125 VDC be applied to the shunt trip coil to cause the breaker to open.
B. Incorrect. Plausible because the UV trip receives power from a DC power supply, but the power supply is 48 VDC within SSPS.
C. Correct. 125 VDC Bus 2ED1 supplies power to the shunt trip coil for Train A Trip Breaker. UV coils and shunt trip relays are supplied from 48 VDC from SSPS. The shunt trip coil is normally de-energized and without power available, a shunt trip of Train A Trip Breaker is not possible.
D. Incorrect. Plausible because the UV trip receives power from a DC power supply, but the power supply is 48 VDC within SSPS and is de-energized to actuate.

Reference:
From LO21.SYS.ES2.LN, Page 66 Revision # 09/02/04 THE SHUNT TRIP COIL The Shunt Trip Coil on the Reactor Trip and Bypass breakers is actuated by any of the following:
- Either Manual Reactor Trip switch
- Either Manual SI Actuation switch
- Auto Shunt Trip Relay STA(B) - only on the Reactor Trip Breakers
- Both Bypass Breakers connected and closed- only on the Bypass Breakers The Shunt Trip Coil is normally de-energized. When it is actuated by applying 125 VDC to its coil, the coil attracts an armature which pushes the trip lever on the breaker trip shaft, causing the breaker to trip (Figure 20). This trip device is a mechanically less complicated and more forceful mechanism than the undervoltage trip coil. The power to the shunt trip coils comes from uED1 (2)-2.

GREEN AMBER RED A. OFF OFF ON B. ON ON ON C. ON ON OFF D. OFF OFF OFF Proposed Answer: C Explanation:
A. Incorrect. Plausible because these are the indications that would be available if the fan were still operating which would occur 40 seconds after a Blackout instead of a Safety Injection (SI), but the fan will load shed on the SI.
B. Incorrect. Plausible if thought that the shunt trip of the breaker caused all lights to illuminate.
C. Correct. The fan is load shed via a shunt trip of the breaker upon receipt of an SI signal. With the handswitch in the AUTO AFTER START position, this will cause the amber light to energize. The green light is on because the breaker is open, which is also why the red light is off.
D. Incorrect. Plausible if thought that the shunt trip of the breaker caused all lights to extinguish, however control power for the circuit is 125 VDC.

A. 43 increase B. 43 decrease C. 50 increase D. 50 decrease Proposed Answer: C Page 58 of 93 CPNPP NRC 2013 RO Written Exam Worksheet 1 to 25 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible because the pump head will increase when the Flow Control Valve is closed, however, with Adverse Containment parameters this action should not be taken until the level in the ruptured Steam Generator is a minimum of 50%.
B. Incorrect. Plausible if thought that overall flow would increase when the Flow Control Valve is closed as occurs with other pumps (i.e., the miniflow valve opens when the normal discharge path is closed). However, with the Auxiliary Feedwater Pumps the miniflow is open throughout the evolution. Additionally, with Adverse Containment parameters this action should not be taken until the level in the ruptured Steam Generator is a minimum of 50%.
C. Correct. Given the conditions listed, once Steam Generator level rises above 50%, the Flow Control Valve should be closed restricting the pump discharge to only miniflow, this restriction of the discharge flow will result in an increase in discharge pressure.
D. Incorrect. Plausible because once Steam Generator level rises above 50%, the Flow Control Valve should be closed restricting the pump discharge to only miniflow. If thought that overall flow would increase when the Flow Control Valve is closed as occurs with other pumps (i.e., the miniflow valve opens when the normal discharge path is closed), and discharge pressure could decrease.
However, with the Auxiliary Feedwater Pumps the miniflow is open throughout the evolution.

From LO21.SYS.MR1 p. 32 Revision 6-9-2011 Main Steam Line Radiation Monitors To detect SG primary-to-secondary tube leakage, each Main Steam line is equipped with a two types of adjacent-to-line (ATL) radiation monitors. Using different detector types and discrimination settings, the monitors are capable of detecting a range of very small to very large leakage amounts. The first monitor type meets the accuracy and range requirements of Regulatory Guide 1.97 and detects gross gamma radiation emitted during radioactive decay of noble fission product gases, particularly Xe-133.
The second monitor type detects N-16 gamma radiation produced during reactor operation.
Located between the ARV and the first SG safety valve of each steam line, Main Steam Line Monitors (u-RE-2325 u-RE-2328) are Geiger Mueller type detectors. Because direct measurement of the steam beta radiation activity concentration is not possible, Main Steam Line Monitors measure the equivalent gamma radiation dose rates adjacent to the steam line. Gamma radiation is given off during beta minus decay of noble gases such as Xe-133. To prevent area (background) radiation from affecting the detector response and indication, the detector is mounted inside a 3 1/4" lead shield with a thin steel window facing the steam pipe. The major limitation of these monitors is they are not sensitive to small leak rate changes and are therefore limited to post-accident assessment of significant releases. They are only capable of detecting primary-to-secondary leakage beginning at around 3600 gallons per day (2.5 gpm). Two Main Steam Line Monitors interface with a single remote RM-80 microprocessor.
Located just upstream of the MSIV for each steam line, the Steam Generator Leak Rate Monitors (u-RE-2325A u-RE-2328A) is an insulated, lightly shielded gamma scintillator type detector, sensitive to N-16 at 6.13 MeV. By utilizing the response of the N-16 gamma, this monitor provides early detection of very small amounts of primary-to-secondary leakage in the gallons-per-day (gpd) range. If primary-to-secondary leakage or a Steam Generator Tube Rupture (SGTR) were to occur while the reactor is at power, this monitor provides a rapid and clear indication of a primary-to-secondary leak. Once the reactor trips, production of N-16 essentially ceases, so readouts typically return to their normal levels.
This radiation monitor is capable of detecting SG tube leakage ranging from about 1 gallon per day
(.0007 gpm) up to 150 gallons per day. Two Steam Generator Leak Rate Monitors interface with a single remote RM-80 microprocessor.

Reference:
From LO21.SYS.SB1 p. 27 Revision 5-7-2011 EFFECTS ON SG BLOWDOWN The effects of a Steam Generator Tube Leak/Rupture on the SG Blowdown System are significant. If activity levels reach the threshold limit for radiation monitor u-RE-4200, then flow through the system is stopped by the SG Blowdown Isolation Valves closing. This prevents the SG Blowdown System from spreading the radioactive elements to other secondary plant components. Another effect is exhaustion of the resin in the systems demineralizers. The SG Blowdown Systems demineralizers utilize resin specifically designed to remove ionic impurities found in the secondary plant water. Introduction of reactor coolant into the blowdown stream provides the demineralizers access to additional ionic impurities and boron. These additional ionic impurities and boric acid cause rapid depletion of the resin.
Once the resin is exhausted, radioactivity levels increase in the blowdown stream. When radioactivity levels reach 1.0 X 10-5 µci/cm3, an annunciator on the Main Control Board warns the operator of a trouble alarm on the SG Blowdown Control Panel. Prior to receiving the annunciator alarm, the PC-11 will sound an audible alarm and provide information of the radiation monitor in "ALERT" status.
Shortly after these alarms, flow through the SG Blowdown System isolates when the radiation monitor reaches its "ALARM" setpoint.

Power for the CRDMs is supplied by two motor-generator sets. They are each comprised of a three phase induction motor directly coupled to a solid steel flywheel and a synchronous alternator. Each MG is operating from separate 480-volt, three-phase buses (uB3 and uB4). The generators are paralleled through Westinghouse type DB-416 circuit breakers. Each generator is a synchronous type, rated at 438 KVA, 260 VAC phase to phase, 150 VAC phase to neutral, zig-zag-wye connected, with brushless excitation from a static voltage regulator and 58.5-59.7 Hertz. The generator output breakers are in the bottom of the MG set switchgear panel. Control switches are on the panel and an automatic synchronizing circuit is installed inside.

- Unit 1 is at 100% power.
- Centrifugal Charging Pump (CCP) 1-01 is running.
- Letdown is established at 120 gpm.
- Actual Volume Control Tank (VCT) level is 58% and lowering.
- VCT level channel 1-LT-112 fails high.
Which of the following predicts the impact on Pressurizer Level Control?
Pressurizer Level will...
A. ...remain stable as Reactor Makeup initiates automatic makeup at 46% and results in VCT level cycling between 46% and 56%; CCP 1-01 maintains Net Positive Suction Head.
B. ...NOT remain stable as Reactor Makeup initiates automatic makeup at 46% but VCT level will continue to lower; CCP 1-01 will lose Net Positive Suction Head as suction will NOT automatically shift to the Refueling Water Storage Tank.
C. ...remain stable as Reactor Makeup does NOT initiate automatic makeup; CCP 1-01 maintains Net Positive Suction Head as suction automatically shifts to the Refueling Water Storage Tank.
D. ...NOT remain stable as Reactor Makeup does NOT initiate automatic makeup; CCP 1-01 will lose Net Positive Suction Head as suction will NOT automatically shift to the Refueling Water Storage Tank.
Proposed Answer: D Page 12 of 92 CPNPP NRC 2013 RO Written Exam Worksheet 26 to 50 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible because automatic makeup would be initiated when 1-LT-112 level channel lowered to 46% and the cycling setpoint is correct, however, 1-LT-112 will continue to indicate 100% VCT level. Thus automatic makeup will not occur and maintain VCT level in the band.
B. Incorrect. Plausible because automatic makeup would be initiated when 1-LT-112 level channel lowered to 46%, however, charging flow is exceeding automatic makeup capability and therefore VCT level could be thought to continue trending down even with automatic makeup, however, with RCP Seal Return flow included VCT level would not continue to drop if automatic makeup to the VCT was occurring..
C. Incorrect. Plausible because automatic makeup will not be initiated, however, the Centrifugal Charging Pump suction remains aligned to the VCT as both 1-LT-112 and 1-LT-185 must indicate 2% for suction to swap to the RWST and 1-LT-112 is failed to 100%.
D. Correct. As outlined in ALM-0061A, VCT level will not actuate at 46% as 1-LT-112 is failed to 100%. Additionally, CCP suction will not transfer to the RWST as both 1-LT-112 and 1-LT-185 must indicate 2% for suction to swap to the RWST and 1-LT-112 is failed to 100%. CCP 1-01 will lose suction and Pressurizer Level will lower dramatically.

The valve will continue to position further to the recycle holdup tank if level increases above setpoint. At 98% level from the other level transmitter, u-LT-0185, a solenoid operated valve directs full air pressure to the valve positioner to fully position u-LCV-0112A to the recycle holdup tank.
The 62% setpoint for initiating diversion of letdown to the recycle holdup tank is based on maintaining a gas volume in the volume control tank sufficient to absorb the liquid which results from a 4F error in Tave during a 0 to 100% power swing and which is not absorbed by the pressurizer.
Volume Control Tank Level Transmitter u-LT-0112A actuates level bistables which initiate automatic makeup to the volume control tank at 46% level and stop automatic makeup at 56% level.
At 2% level (low-low level) on both u-LT-0112 and u-LT-0185, the charging pump suction piping will automatically realign to the refueling water storage tanks. The low-low level realignment opens the parallel charging pump suction valves from the RWST (u-LCV-0112D and u-LCV-0112E) and closes the series charging pump suction valves from the VCT (u-LCV-0112B and u-LCV-0112C). The charging pump suction may be manually realigned after the volume control tank level returns to > 16%
on either channel.

Proposed Answer: B Page 17 of 92 CPNPP NRC 2013 RO Written Exam Worksheet 26 to 50 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible if believed that Data A was powered from 1C1 and Data B was powered from 1C14 during normal alignment, however all of DRPI is powered from 1C14 which is normally powered from 1C1.
B. Correct. As DRPI is powered from 1C14, which is normally aligned from 1C1, a loss of 1C1 would result in a loss of DRPI. In accordance with ABN-712, the power supply should be shifted to 1C4.

Reference:
From LO21.SYS.RC3.LN, Page 14 Revision # 02/10/04 COMPONENTS CORE COOLING MONITOR SYSTEM (CCM)
Two qualified, redundant CCM's are used for Inadequate Core Cooling (ICC) monitoring. Each CCM is designed to indicate Core Exit Thermocouple temperatures (CET function) and to monitor the RCS Subcooling Margin Monitor (SMM function).
CORE EXIT THERMOCOUPLES To provide input temperature data to the CCM microprocessor, the NSSS-supplied array of fifty CET's has been divided into two separate, redundant trains with each set having a distribution representative of all four quadrants of the reactor core exit area. The planar locations of the CETs with respect to the core fuel assembly position are illustrated on Figure 2. All CET's are axially located just above the Upper Core Plate as illustrated in Figure3.
Each CET is a type K (chromel-alumel) thermocouple contained within an aluminum-oxide insulated, stainless steel sheathed cable (1/8" OD). Each cable passes through one of four vessel head penetrations (located 90º apart and near the core periphery) which contain pressure-boundary sealing assemblies. Figure 2 includes indication of head penetration assignments for the various T/C cables, separated into groups of either twelve or thirteen cables per penetration.
Above the vessel head, the CET cables are grouped into two separate trains. Each train is routed into a separate reference junction box which contains three platinum resistance temperature detectors (RTD's): two used for reference temperature measurements plus one installed spare. These reference measurements permit the transition from chromel-alumel leads to copper conductors for signal transmission to the CCM microprocessor (Figure 4).
The CET signals are used in the CCM to monitor coolant temperatures over the entire range including normal operating conditions and extending to beyond accident extremes. Each thermocouple is constantly checked, by the CCM computer, for open or shorted conditions, and the signal is adjusted to account for the inside containment cold reference junction conditions based on the reference RTD measurements. The highest valid CET signal is displayed on the Control Board and is also employed by the microprocessor to determine the RCS saturation margin.

Proposed Answer: B Page 30 of 92 CPNPP NRC 2013 RO Written Exam Worksheet 26 to 50 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible because with the Fuel Transfer Tube Gate Valve open there is a potential for transferring water, however, there is insufficient differential pressure developed because both doors of the Personnel Airlock are open.
B. Correct. As outlined in the NOTE in SOP-801A, when the Equipment Hatch is off and the Personnel Airlock is open then 1-HS-5572 is closed to ensure that air flow is from the Safeguards Building into the Containment. This is contrary to the normal pressure within the Safeguards Building during MODES 1 through 4 when it is maintained at a slight negative pressure to ensure contaminants can be monitored via the Primary Plant Ventilation System.
C. Incorrect. Plausible because with the Fuel Transfer Tube Gate Valve open there is a potential for transferring water, however, there is insufficient differential pressure developed because both doors of the Personnel Airlock are open.

Reference:
From LO21.SYS.MT1 Revision 5/4/11 The Turbine-Generator load is controlled by stop and control valves. The stop valves admit steam to the turbine as operating conditions require, and provide extremely fast closure to isolate the turbine from the steam supply system in the event of a protective device actuation. This rapid closure of the stop valves is referred to as a turbine trip. The control valves regulate the amount of steam admitted to the Main Turbine to control the output load of the Main Generator or the speed of the turbine during startup.
Steam flow to the LP Turbines is regulated by the EHC system which uses hydraulic fluid pressure to position control valves in response to various inputs much like the HP Stop and Control valves. The LP Stop and Control valves are normally fully open with Turbine-Generator load being controlled by the HP Turbine.
During normal operation the LP Control Valves are fully open and will only throttle down upon a large loss of electrical load to help prevent overspeeding of the Main Turbine.

B. Reactor at 75% power with a General Warning for Train B SSPS ONLY.
C. Reactor Trip with a General Warning for BOTH Train A and Train B SSPS and a First Out Alarm illuminated.
D. Reactor Trip with a General Warning for BOTH Train A and Train B SSPS and NO First Out Alarm illuminated.
Proposed Answer: C Page 46 of 92 CPNPP NRC 2013 RO Written Exam Worksheet 26 to 50 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation: For this question we assumed the Reactor Trip status panel is equivalent to our First Out Panel.
A. Incorrect. Plausible because a General Warning is generated for a loss of either 48 VDC power supply. If this were the only General Warning the Unit would remain at power, but performing testing on the other train generates a General Warning for both trains and the Unit trips.
B. Incorrect. Plausible because a General Warning is generated while performing testing on SSPS. If this were the only General Warning the Unit would remain at power, but a loss of either 48 VDC power supply on the other train generates a General Warning for both trains and the Unit trips.
C. Correct. Testing on one train of SSPS generates a General Warning. A loss of any of the four DC power supplies in the other train of SSPS also generates a General Warning. General Warnings in both trains of SSPS causes the Reactor Trip Breakers to open, which then causes the Turbine to trip. Since the power level is above 50%, the Turbine trip then causes a Reactor trip signal to be generated which causes the First Out annunciator. The First Out annunciator would NOT alarm if power were below 50%.
D. Incorrect. Plausible because a Reactor Trip is generated, but a First Out annunciator occurs due to the Unit being above P-9 (50%) power for RX > 50% PWR TURB TRIP.

ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Proposed Answer: C Explanation:
A. Incorrect. Plausible as Natural Circulation does NOT exist, however, the MSIVs would have closed at 6.2 psig Containment pressure and thus the Steam Dump Valves are isolated.
B. Incorrect. Plausible as three of the four Steam Generators appear to be coupled. However, adequate subcooling does not exist and one Steam Generator is uncoupled. Additionally, the CETs are increasing which indicates that adequate Natural Circulation does NOT exist. Steam Generator 3 appears to be overcooling, thus the concept to decrease steam dumping from this generator is plausible, however, the low temperature indicates lack of circulation and Cold Leg temperature lowering as a result of ECCS flow.
C. Correct. Since adequate subcooling does NOT exist, CETs are increasing and SG 1-03 is uncoupled, which indicate that Natural Circulation does NOT exist. EOS-1.2A, states to increase dumping steam to promote Natural Circulation. The Steam Dump Valves are isolated by the MSIVs which only leave the Atmospheric Relief Valves for dumping steam.
D. Incorrect. Plausible as three of the four Steam Generators appear to be coupled. However, adequate subcooling does not exist and one Steam Generator is uncoupled. Additionally, the CETs are increasing which indicates that adequate Natural Circulation does NOT exist. Steam Generator 3 appears to be overcooling, thus the concept to decrease steam dumping from this generator is plausible, however, the low temperature indicates lack of circulation and Cold Leg temperature lowering as a result of ECCS flow.

- Unit 1 has experienced a Large Break Loss of Coolant Accident.
- A transition has been made to EOS-1.3A, Transfer to Cold Leg Recirculation.
- Emergency Core Cooling System (ECCS) has been transferred to Cold Leg Recirculation and the RWST level is 8% and lowering.
- The following ECCS pumps are running:
- Centrifugal Charging Pumps (CCP) 1-01 and 1-02.
- Safety Injection Pumps (SIP) 1-01 and 1-02.
- Residual Heat Removal Pumps (RHRP) 1-01 and 1-02.

D. CCP 1-01 to prevent pump damage.
Proposed Answer: C Page 62 of 92 CPNPP NRC 2013 RO Written Exam Worksheet 26 to 50 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible as securing SIP 1-01 would cause the greatest improvement to RHRP 1-01 NPSH, however RHRP 1-01 should be secured due to cavitation.
B. Incorrect. Plausible as securing CCP 1-01 would cause some improvement to RHRP 1-01 NPSH, however RHRP 1-01 should be secured due to cavitation.
C. Correct. Because the CAUTION in EOS-1.3A states to stop any ECCS Pump which loses suction or shows indication of cavitation should be stopped to prevent pump damage and the suction supply to the SIPs and CCPs is cross-connected so that either RHRP will provide adequate suction. The 8804 valves in the RHR system and the 8807 valves in the SI system provide this dual suction source alignment.
D. Incorrect. Plausible since CCP 1-01 is most susceptible to damage due to cavitation and if RHRP 1-01 were the only suction source to CCP 1-01 this action would be appropriate. However, there is no indication of CCP 1-01 cavitation.

Reference:
From LO21.SYS.PP1 Revision 5/5/11 During normal plant operations, the pressurizer is filled with boiling water and steam. The temperature of the boiling (or saturated) water determines the pressure inside the entire Reactor Coolant System. Pressurizer temperature is controlled to regulate RCS pressure by energizing electric heaters in the bottom of the pressurizer to raise pressure, and by spraying the steam space (or steam bubble) in the top of the pressurizer with cooler water to reduce pressure.
Under normal operating conditions, the Pressurizer Pressure Control System will automatically maintain the plant at 2235 psig. Heaters maintain a saturated condition in the pressurizer and spray valves throttle open to hold pressure at the 2235 psig setpoint. Backup banks of heaters energize on decreasing RCS pressure. On increasing pressure, spray valves open automatically to cause partial steam bubble condensation.
Comments /
Reference:
From DBD-ME-250 Reactor Coolant System Revision 45 The pressurizer spray valves are required to pass the maximum cold leg spray flow sufficient to maintain the system pressure below the power operated relief valve setpoint for a 12 percent load rejection at 100 percent power.
The pressurizer spray line is required to deliver 900 gpm to the pressurizer.
RCS pressure is controlled by the use of the pressurizer where water and steam are maintained in equilibrium by electrical heaters and water sprays. Steam can be formed (by the heaters) or condensed (by the pressurizer spray) to reduce pressure variations due to contraction and expansion of the reactor coolant.

From LO21.SYS.MR1.LN, Page 8 Revision 06/09/11 Turbine Driven Auxiliary Feedwater Pump Steam Supply Redundant valves and piping provide a secure steam supply to the Turbine Driven Auxiliary Feedwater Pump (TDAFWP) over a range of steam pressures from the lowest set main steam safety valve plus 3%
accumulation (1185 psig +3% = 1221 psig or 1236 psia) to the lowest SG pressure (100 psia on the secondary side) associated with RHR cut-in conditions at 350F. The design ensures the TDAFWP can be operated even if one steam supply valve fails to open upon demand.
Normally closed isolation valves to the TDAFWP have the capability to open upon loss of all AC power. Fail open air operated valves are used for this application therefore, air accumulators tanks are provided to permit valve closure following the loss of air.
These valves are required to be closed following a SGTR to mitigate radiological consequences. Thus the air accumulators must contain sufficient air capacity to drive each valve closed and maintain it closed post accident until an operator can be dispatched to manually isolate the associated steam line.

The governor actuator is also driven by the turbine rotor via spiral reduction gears driven by the same worm gear as the oil pump. The governor servomotor receives oil from the actuator and is the lowest point in the oil system. To ensure proper operation, the oil level in the governor oil sight glass should be maintained at the levels specified in the operating procedures (U1 and U2 require slightly different levels). Obviously, a low oil level would damage the regulator or prevent operation, but high oil levels are also undesirable. This is because the oil may foam causing the regulator to operate improperly.

Facility's heat removal systems, including primary coolant, emergency coolant, the decay heat removal systems and relations between the proper operation of these systems to the operation of the facility Proposed Question: Common 54 Given the following conditions:
- The crew believes that the leak outside of Containment has been isolated but Reactor Coolant System pressure is not rising.
Which of the following alternate indications may be used to determine if the break has been isolated per ECA-1.2A, LOCA Outside Containment?
A. Refueling Water Storage Tank level stable.
B. Reactor Vessel Level Indicating System indication rising.
C. Emergency Core Cooling System flows rising.
D. Emergency Core Cooling System alignment verification.
Proposed Answer: B Explanation:
A. Incorrect. Plausible because RWST inventory could be lost to the Safeguards Building from an interfacing system break outside Containment and RWST level stable could indicate that break flow has ceased, however, RWST level may still be lowering with the break isolated as ECCS flow refills the RCS. Therefore, RWST level change is not a good indicator of break isolation.
B. Correct. As stated in Attachment 2, Step 3 Bases, RCS pressure may not initially rise once the break is isolated, due to plant cooldown or when the RCS is saturated. RVLIS indication rising shows that ECCS flow is not leaving the RCS via the break, but rather it is refilling the RCS. This indicates that the break is isolated from the RCS.
C. Incorrect. Plausible because ECCS flows could indicate that the break is isolated if it were lowering. Rising ECCS flow is indicative of the RCS break becoming worse.
D. Incorrect. Plausible because an ECCS valve alignment is performed in Step 1 of ECA-1.2A, and this may isolate the break, however, verifying ECCS alignment alone does not ensure that the break is isolated. RCS parameters, such as pressure and RVLIS trend must be evaluated to verify break isolation.

Proposed Question: Common 57 Given the following conditions:
- Unit 1 is operating at Middle-of-Life 100% power.
- 1/1-RBSS CONTROL ROD BANK SELECT is in MANUAL.
- T AVE -T REF Deviation is 0ºF and stable.
- Control Bank D Control Rod H-8 drops to the bottom of the core.
After the Control Rod drops the following conditions exist:
- T AVE -T REF Deviation is -7.5ºF and stable.
- Reactor Power is 99% and stable.
What is the reactivity worth of Control Rod H-8?
A. 153 pcm B. 138 pcm C. 133 pcm D. 123 pcm Proposed Answer: A Page 28 of 60 CPNPP NRC 2013 RO Written Exam Worksheet 51 to 64 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation:
A. Correct. In accordance with the provided MOL Reactivity Briefing Sheet a 7.5ºF lower temperature would be equivalent to -7.5 x -18.4 = 138 pcm/ºF plus a 1% power change which would be equivalent to 1 x 15.3 = 15.3 pcm/% RTP; therefore the total reactivity worth of the Control Rod would be 138 + 15.3 = 153 pcm.
B. Incorrect. Plausible as 138 pcm would be equivalent to the reactivity change from the temperature change only.
C. Incorrect. Plausible as 133 pcm would be calculated if the power and temperature coefficients were reversed in the calculation, -7.5 x 15.3 = 115 plus 1 x 18.4 = 18; 115 + 18 = 133 pcm.
D. Incorrect. Plausible as 123 pcm would be calculated if the reactivity change from power was subtracted from the reactivity change due to temperature; 138 - 15.3 = 123 pcm.

- Unit 1 is at 100%.
- Pressurizer level is stable.
- 1-TI-126, Regenerative Heat Exchanger Letdown Outlet temperature is 250ºF.
- 1-TI-127, Regenerative Heat Exchanger Charging Return temperature is 500ºF.

D. Loss of air to 1-PCV-131, Letdown Pressure Control Valve.
Proposed Answer: A Page 31 of 60 CPNPP NRC 2013 RO Written Exam Worksheet 51 to 64 Rev h
ES-401 CPNPP NRC 2013 RO Written Exam Worksheet Form ES-401-5 Explanation:
A. Correct. A leak in this location would divert cooling flow (Charging) from the Regenerative Heat Exchanger resulting in higher Letdown temperatures out of the Regenerative Heat Exchanger and the Charging temperature returning to the loop would also be higher than normal and also result in lowering Pressurizer level.
B. Incorrect. Plausible because it could be thought that this leak location would result in these indications, however, a leak in Letdown upstream of the Regenerative Heat Exchanger would reduce the flow though the Heat Exchanger and result in a lower rather than higher temperature.
C. Incorrect. Plausible if thought that this failure reduced the flow of Charging and caused higher Letdown temperatures from the Regenerative Heat Exchanger and lowering Pressurizer level, however, the valve fails OPEN which would yield lowering Letdown temperatures from the Regenerative Heat Exchanger and rising Pressurizer level.
D. Incorrect. Plausible because this failure would result in the higher Letdown temperatures from the Regenerative Heat Exchanger and lowering Pressurizer level, however, on a loss of air to the Letdown Pressure Control Valve the Letdown pressure would be much lower than normal instead of at or slightly above normal pressure.

From LO21.SYS.CS1.LN, Page 12 Revision # 04/28/11 REGENERATIVE HEAT EXCHANGER The regenerative heat exchanger is a stainless steel heat exchanger, located in containment in a shielded room on the 832' elevation. It is a counter flow design with charging return flow through the tube side and letdown flow on the shell side. Letdown enters the heat exchanger at reactor coolant system cold leg temperature and pressure and passes through baffles, which create crossflow to increase the contact between the hot letdown and the relatively cold charging flow. This allows more heat transfer between the two fluids. By utilizing a regenerative heat exchanger, the amount of heat lost from the primary system and the thermal stresses that exist at the loop charging penetrations are reduced.
During normal power operations the regenerative heat exchanger reduces letdown temperature from 560°F to approximately 260°F and raises charging water temperature to approximately that of the reactor coolant system cold loop.
Temperature of the charging flow leaving the regenerative heat exchanger is provided by thermowell-mounted RTD and indicated on CB-06 (u-TI-0126, 100-600°F) and on the plant computer.
Temperature of the letdown flow leaving the regenerative heat exchanger is provided by thermowell-mounted RTD and indicated on CB-06 (u-TI-0127, 100-600°F) and on the plant computer. This device also actuates an alarm (REGEN HX LTDN OUT TEMP HI) at >400°F.

During normal power operations the valve functions to automatically maintain upstream pressure at the established setpoint, which is normally 310 psig. By maintaining a back-pressure on the system, the hot letdown fluid between the letdown orifices and the letdown heat exchanger is maintained in a subcooled condition.
The saturation temperature of water at 310 psig is approximately 425°F. The temperature of letdown leaving the regenerative heat exchanger is normally 260°F, which is approximately 165°F below saturation temperature. An alarm (REGEN HX LTDN OUT TEMP HI, set at >400°F) will warn of temperature approaching saturation temperature for this portion of the letdown piping.
Letdown Heat Exchanger Outlet Pressure Control Valve, u-PCV-0131, is air operated and fails fully open on a loss of air or control power.

It provides the differential pressure which is related to charging flow to Charging Pump Discharge Flow Transmitter u-FT-0121 (located, for Unit 1, in the boric acid storage tank room and, for Unit 2, in the Unit 2 CVCS valve operating room on the 822 foot elevation of the auxiliary building. The flow transmitter functions to generate a current signal which is proportional to charging header flow (from 0 to 270 gpm) for indication and control of charging flow. Charging Flow Indicators u-FI-0121A and u-FI-0121B (0 to 270 gpm) are located on CB-06 and at the remote shutdown panel, respectively. Charging flow is provided as an input to the plant computer. The CHG FLO HI/LO alarm on CB-06 also receives its inputs from the charging flow transmitter and is set to actuate at > 150 gpm and at < 55gpm.
The discharge flow from the centrifugal charging pumps to the normal charging header and to the reactor coolant pump seal injection lines is controlled by regulating the position of CCP u-01/u-02 Charging Flow Control Valve, u-FCV-0121, located in the charging pump valve room. This valve is air operated, and fails open on loss of air or control power.

D. ...above 90% to compensate for the level decrease due to eliminating a non-condensable void.
Proposed Answer: C Explanation:
A. Incorrect. Plausible because IF a Reactor Coolant Pump CANNOT be started, EOS-0.4B contains guidance to maintain Pressurizer level between 30% and 40%. However, level will decrease due to void collapse when a Reactor Coolant Pump is started, and must be established at greater than 90%.
B. Incorrect. Plausible because IF a Reactor Coolant Pump CANNOT be started, EOS-0.4B contains guidance to maintain Pressurizer level between 30% and 40%. However, level will decrease due to void collapse when a Reactor Coolant Pump is started, and must be established at greater than 90%.
C. Correct. Pressurizer level is maintained above 90% to accommodate void collapse when starting the first Reactor Coolant Pump.
D. Incorrect. Plausible because the Pressurizer level value is correct, however, if non-condensable gases were indicated, they would be addressed via FRI-0.3B, Response to Voids in Reactor Vessel.

- Unit 1 is operating at 100% power.
- ABN-302, Feedwater, Condensate, Heater Drain System Malfunction, is being performed due to a trip of Main Feedwater Pump 1-01.
Which of the following alarms is NOT CONSISTENT with given plant conditions?
A. 1-ALB-8A, Window 2.12 - SG 2 LEV DEV B. 1-ALB-6D, Window 1.10 - AVG TAVG - TREF DEV C. 1-PCIP Window 3.4 - TURB LOAD REJ STM DMP ARMED C-7 D. 1-ALB-6D, Window 4.14 - CONTROL ROD BANK D FULL WTHDRWL Proposed Answer: D Explanation:
A. Incorrect. Plausible if believed that the automatic runback coupled with feedwater control valve response will maintain steam generator water level within 5% of program. However, the large feedwater flow transient caused by the trip of a Main Feedwater Pump will cause steam generator level deviations of sufficient magnitude to cause level deviation alarms.
B. Incorrect. Plausible if believed that automatic rod control will maintain T AVE within 2.5°F of T REF .
However, the rate of turbine power decrease due to the automatic runback (35%/minute) will cause T AVE -T REF deviation to go above the alarm setpoint.
C. Incorrect. Plausible if believed that the automatic runback following a Main Feed Pump trip occurs at the normal runback rate of 10 MW/minute. However, the automatic runback occurs at 35%/minute, which is greater than the 10% power per 120 second arming setpoint for C-7.
D. Correct. When a Main Feedwater Pump trips, a turbine runback is automatically initiated. This will cause control rods to step in due to a mismatch in turbine and reactor power. Control Bank D will not move out to 223 steps and 1-ALB-6D, Window 4.14 should not alarm.

HA2.1 Alert Fire or explosion resulting in EITHER:
- Visible damage to any Table H-1 structures
- Control Room indication of degraded performance of systems required to establish or maintain safe shutdown Mode Applicability:
All Basis:
Generic VISIBLE DAMAGE is used to identify the magnitude of the FIRE or EXPLOSION and to discriminate against minor FIRES and EXPLOSIONS.
The reference to structures containing safety systems or components is included to discriminate against FIRES or EXPLOSIONS in areas having a low probability of affecting safe operation. The significance here is not that a safety system was degraded but the fact that the FIRE or EXPLOSION was large enough to cause damage to these systems.
The use of VISIBLE DAMAGE should not be interpreted as mandating a lengthy damage assessment prior to classification. The declaration of an Alert and the activation of the Technical Support Center will provide the Emergency Coordinator with the resources needed to perform detailed damage assessments.
The Emergency Coordinator also needs to consider any security aspects of the EXPLOSION.

ES-401 CPNPP NRC 2013 SRO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible if believed that the ruptured steam generator is not isolated due to steam generator pressure not rising. Additionally, transition to ECA-3.1A would be correct following actions in EOP-3.0A if the steam generator remained faulted. However, the fact that steam generator pressures are stabilizing indicates steam generator isolation. Additionally, ECA-3.1A cannot be entered directly from ECA-2.1A.
B. Incorrect. Plausible because this is the procedure in effect, however, the ECA-2.1A Foldout Page requires a transition to EOP-3.0A on any Steam Generator with an increasing level.
C. Correct. ECA-2.1A Foldout Page requires a transition to EOP-3.0A on any Steam Generator with an increasing level.
D. Incorrect. Plausible because with the Pressurizer empty it could be thought that a transition to EOP-1.0A is appropriate due to SI Reinitiation Criteria, however, EOP-3.0A entry is required.

A. ...the reduced ECCS flow requirements when less than 350°F.
B. ...a mass addition pressure transient being relieved by a single PORV.
C. ...not exceeding the maximum flow rate to the RCS when less than 350°F.
D. ...preventing excessive cooldown of the Reactor Vessel Cold Leg nozzle.
Proposed Answer: B Explanation:
A. Incorrect. Plausible because there is a reduced ECCS flow requirement in MODE 4 when only one ECCS train shall be OPERABLE per Technical Specification LCO 3.5.3, however, limitations for the Charging Pumps are based on a single PORV in service.
B. Correct. As outlined in Technical Specification Surveillance Requirement (SR) 3.4.12.1.
Additionally, analyses demonstrate that either one RCS relief valve or the depressurized RCS and RCS vent can maintain RCS pressure below limits when only two charging pumps are actuated.
Thus, the LCO allows only two charging pumps OPERABLE during the LTOP MODES.
C. Incorrect. Plausible because there are Low Temperature Overpressure Protection System requirements while in MODE 4, however, limitations in the LCO are not applicable when >320°F with one RCP and operation, Pressurizer level 92%, and heat up rate limited to 60°F per hour.
D. Incorrect. Plausible because The Reactor Vessel Cold Leg Nozzles are referenced in Technical Specification LCO 3.5.3 Bases, however, limitations for the Charging Pumps are based on a single PORV in service.

ES-401 CPNPP NRC 2013 SRO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible with the TDAFWP inoperable and one MDAFWP feeding all four Steam Generators, all three AFW pumps are inoperable. This would be the correct action if believed the LCO 3.0.3 were entered for this Condition. However, LCO 3.7.5 Condition D NOTE states that LCO 3.0.3 should not be entered.
B. Incorrect. Plausible if believed that the TDAFWP and MDAFWP 1-02 were the only inoperable pumps as this is the correct actions for two trains of AFW inoperable.
However, cross-connecting the MDAFWP 1-01 to feed all four Steam Generators makes MDAFWP 1-01 inoperable as well. This would be the correct action for LCO 3.7.5 Condition C.
C. Incorrect. Plausible as this action would be indicative of a misunderstanding that the TDAFWP is not required OPERABLE in MODE 3 and thus placing the unit in MODE 3 exits the two trains inoperable LCO 3.7.5 Condition C and therefore 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> would remain of the 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> for Condition B for only one train inoperable. This is not correct, as the allowance for testing the TDAFWP in MODE 3 is for testing purposes only and does not exclude the pump from OPERABILITY requirements in MODE 3.
D. Correct. With the TDAFWP inoperable, MDAFWP 1-02 tripped and MDAFWP 1-01 feeding all four Steam Generators, all three AFW trains are inoperable in accordance with ABN-305 Note. LCO 3.7.5 Condition D is correct for all three trains inoperable.

Proposed Answer: A Page 14 of 50 CPNPP NRC 2013 SRO Written Exam Worksheet 89 to 100 Rev h
ES-401 CPNPP NRC 2013 SRO Written Exam Worksheet Form ES-401-5 Explanation:
A. Correct. Void formation in the downcomer will cause more neutron leakage outside the vessel and neutron flux SR indication will increase. Continuing with EOP-1.0A is the correct action.
B. Incorrect. Plausible because continuing with EOP-1.0A is the correct action, however, void formation in the downcomer will cause more neutron leakage outside the vessel and neutron flux SR indication will increase.
C. Incorrect. Plausible because void formation in the downcomer will cause more neutron leakage outside the vessel and neutron flux SR indication will increase. However, with the conditions listed, the highest transition to FRS-0.2A would be via a yellow path which does not take precedence over EOP-1.0A actions.
D. Incorrect. Plausible if believed that void formation would cause source range neutron instrumentation level to increase due to an increased fission rate, however, void formation in the downcomer will cause more neutron leakage outside the vessel and neutron flux SR indication will increase.

ES-401 CPNPP NRC 2013 SRO Written Exam Worksheet Form ES-401-5 Explanation:
A. Correct. In accordance with EOP-0.0A Bases Table 1 stopping RCPs 1-01 and 1-04 will essentially stop spray flow through loop 1 spray valve. With pressurizer level at 25% spray flow will be negligible from RCPs 1-02 and 1-03.
B. Incorrect. Plausible as RCP 1-01 is the primary driving head for spray flow through 1-PCV-455B; however the EOP-0.0A Bases Table 1 shows that RCP 1-04 will still supply spray flow and therefore RCP 1-04 should also be stopped.
C. Incorrect. Plausible as RCP 1-04 is known to produce the greatest spray flow and therefore is logical to stop. Additionally stopping RCP 1-02 would lower the driving head farther. However, since 1-PCV-455B is primarily driven from the discharge of RCP 1-01, spray flow is maintained with RCPs 1-01 and 1-03 running.
D. Incorrect. Plausible as RCP 1-04 is known to produce the greatest spray flow and therefore is logical to stop. However, since 1-PCV-455B is primarily driven from the discharge of RCP 1-01, spray flow is maintained with RCPs 1-01, 1-02 and 1-03 running.

Proposed Answer: C Page 34 of 50 CPNPP NRC 2013 SRO Written Exam Worksheet 89 to 100 Rev h
ES-401 CPNPP NRC 2013 SRO Written Exam Worksheet Form ES-401-5 Explanation:
A. Incorrect. Plausible because it could be evaluated that no procedural transitions have yet been identified, however, indications are correct for a transition to ECA-1.2A.
B. Incorrect. Plausible because with none of the major accident (SGTR, Faulted SG or LOCA) transitions identified, it could be interpreted that SI Termination should take place, however, subcooling would not allow SI Termination and a transition to ECA-1.2A is correct.
C. Correct. Interpretation of the readings on Grid 4 Radiation Monitors indicates that a transition to ECA-1.2A is required.
D. Incorrect. Plausible because the major diagnostic steps of EOP-0.0A have been completed, however, transition from EOP-0.0A to EOS-0.0A is not proper when a transition has not been identified.
