Lesson Plan Reactor Coolant Pumps SY1300300, Rev. 011 The double dam design permits the injection of water, from the Reactor Makeup Water System, between the dams (a total of 800cc/hr). A portion of this flow (400 cc/hr) goes into the cavity between the No. 2 and No. 3 seals and then out the No. 2 seal leakoff which is directed to the RCDT. The remaining flow (400 cc/hr) is discharged through the No. 3 seal leakoff into the containment normal sumps. The purpose of the injected flow is to; 1) provide the No. 3 seal with clean water for lubrication and 2) prevent dissolved radioactive gases in the discharged fluid of the No. 2 seal from entering the containment atmosphere.

The No. 3 double-dam seal has a separate injection system. Reactor Makeup Water (BL) supplied from a 9.75 gal standpipe is injected, at static head of about 10 psig or 23 ft. of water, between the two dams at a rate of 800 cc/hr. A level control valve in the Reactor Makeup Water System operates to automatically maintain the standpipe water level.

The level control valve can also be operated from panel RL021 in the Control Room. A pressure control orifice is installed in the No. 3 injection line connection to compensate for dam profile variations. A check valve is also provided in this location to allow the interdam pressure to support the seal loses during No. 2 seal leakoff high pressure conditions. There is also a check valve located in the No. 2/No. 3 seal combined leakoff line to the RCDT to prevent backflow from the RCDT to seal during high pressure conditions.

Low pressure No. 1 seal leakoff flow originates from the low pressure side of the No. 1 seal. The 3 gpm leakage per pump passes through a remotely operated valve and two leakoff flow meters. It then combines with the flows from the other pumps and returns to the Volume Control Tank. Two meters are required to record the flow over the anticipated range. In the event of a CISA, a seal leakoff relief valve, in CTMT, discharges to the Pressurizer Relief Tank (PRT) to maintain a flowpath through the seals (Seal flow is monitored by leakoff). #1 seal leakoff is also affected by a condition called Electro-Ferrisis. This occurs when the material of the seal develops a charge and ionized hematite particles attach to the seal surfaces causing seal leakoff to decrease.

Vent lines are connected after the meters for calibration purposes. A third meter is also provided for differential pressure. This meter indicates the pressure drop across the No. 1 seal. The meter has a local indicator and a low differential alarm set at 209 psid in the control room. This DP is the difference between the RCS pressure at the pump and the leakoff pressure (normally VCT pressure is > 15 psig, but if Seal Return isolates, this pressure goes to the setpoint of the Seal Return Relief Valve, 150 psig).

The No. 2 seal leakoff of 3 gph per pump (.19 L/min) flows through a loop seal and a flow transmitter and then drains to the Reactor Coolant Drain Tank (RCDT). There are local gauges by the RCDT to indicate the leakoff flow rates.

The No. 3 seal leakoff rate is approximately 800 cc/hr of which 400 cc/hr is discharged with the No. 2 seal leakoff to the RCDT. The remaining 400 cc/hr drains to the containment normal sump.

System Interfaces CHARGING HEADER The seal injection system controls the water supplied to the reactor coolant pump seal assembly. The injection water is supplied to the seal assemblies from the Chemical and Volume Control System (CVCS) by way of the charging pumps. The water discharged by the charging pumps, either the Normal Charging Pump (NCP) or one of the two Centrifugal Charging Pumps (CCP's), enters the combined charging header upstream of BG HCV-182. Closing BG FCV-121 when using one of the CCP's or closing BG FCV-462 when using the NCP, decreases charging flow and thus reduces Seal Injection flow. Closing BG HCV-182 increases total RCP Seal Injection flow by lowering normal charging header flow and increasing the backpressure on BG HCV-182 causing more flow to go to the seals. BG FCV-121 and BG HCV-182 are both air-operated, fail-open valves. Another flowpath for providing seal injection flow are the motor operated seal injection valves (BG HV-8357A or BG HV-8357B ), one on the discharge of each CCP. Seal Injection flow then goes through one of two injection filters, a manual flow control throttle valve (one for OPERATIONS Page: 19 of 47 05/01/01

The plant is currently stable at 50% power.

Which of the following conditions would result in a RX PARTIAL TRIP annunciator and allow the plant to remain at power?

A. Loop 1 Reactor Coolant Pump shaft shear occurs.

B. RCS Flow Transmitter FT-414 high pressure tap ruptures.

C. Loop 2 Reactor Coolant Pump breaker opens.

D. RCS Flow Transmitter FT-424 diaphragm ruptures.

Proposed Answer: D, RCS Flow Transmitter FT-424 diaphragm ruptures.

Explanation: Ans. A is incorrect as a shaft shear above P-8 will cause a trip. Ans. B is incorrect as a high pressure tap rupture will cause all three channels to fail low causing a reactor trip. Ans.

C will result in a reactor trip above P-8. Answer D will only cause one channel to fail as the delta P goes to zero on only the failed channel.

QUESTION # 5 Question Worksheet Examination Outline Cross-reference: Level RO SRO Tier # 1 1 Group # 1 2 K/A # 000027 AK1.01 Importance 3.1 3.4 Proposed Question:

Given the following plant parameters during a Reactor Coolant System (RCS) heatup:

  • RCS Average Temperature 195 0 F
  • Pressurizer pressure 375 psig
  • Pressurizer temperature 410°F
  • Pressurizer level 455" Pressurizer spray valves are opened and pressure remains constant.

Why can't pressurizer pressure be reduced?

A. Saturation is indicated in pressurizer.

B. Subcooling is indicated in the pressurizer.

C. Pressurizer spray flow is inadequate for current conditions.

D. Pressurizer level of 455" is too high for a pressure reduction.

Proposed Answer: B, Subcooling is indicated in the pressurizer.

Explanation Ans. A is incorrect, since sprays would have the effect of reducing pressure with saturation conditions. Ans B. is correct since this indication, derived from using the steam tables, shows that a bubble is not drawn in the pressurizer. Ans. C is incorrect since a RCP will be running by this time during a plant heatup and will supply sufficient driving head to the spray valves. Ans. D is incorrect since pressure could still be maintained with this high level if a bubble were drawn in the PZR, but the given parameters show lack of bubble.

The reactor has tripped from full power and one Pressurizer PORV opened following the reactor trip resulting in an SI actuation. The PORV has stuck open and all attempts to close it or its block valve have failed.

You are reporting the trend as recorded on BB PR-403, RCS WR Pressure Recorder and note that the rate of RCS pressure decrease slowed over a 30 minute period and then the rate suddenly increased.

What caused this to happen?

A. The PORV closed momentarily due to the low pressure and then reopened.

B. SI flow increased as the pressure decreased causing a momentary increase in pressure.

C. The pressure in the PRT increased until the rupture disc failed allowing break flow to increase.

D. Containment cooling caused containment pressure to decrease allowing break flow to increase.

Proposed Answer: C, The pressure in the PRT increased until the rupture disc failed allowing break flow to increase.

Explanation: Ans. A would stop the pressure decrease not reduce it. Ans. B sounds good but if this happened the pressure decrease would not increase again. Ans. C is correct since PRT pressure increases decreasing flow (and pressure drop) until the rupture disc fails and then pressure goes to containment pressure allowing the rate of decrease to increase. Ans. D would take a long time to occur as containment pressure is not very high during this event.

QUESTION # 21 Question Worksheet Examination Outline Cross-reference: Level RO SRO Tier # 1 1 Group # 2 1 K/A # 029 EK1.02 Importance 2.6 2.8 Proposed Question:

Based on the current plant cycle core physics, why is it worse for an ATWT event to occur at low power at the Beginning Of Life (BOL) conditions?

A. The higher SG pressures at lower power remove heat from the RCS at a LOWER RATE; therefore, RCS temperatures RISE to a higher level.

B. The high boron concentration causes the emergency boration to be LESS EFFECTIVE; therefore taking a LONGER time to achieve adequate Shutdown Margin (SDM).

C. The Moderator Temperature Coefficient (MTC) is MORE POSITIVE at lower power; therefore, the expected heat addition INCREASES reactor power.

D. The additional burnable poisons provide LESS heat conduction at lower power; therefore, the fuel pin outer clad temperatures are HIGHER.

Proposed Answer: C, The Moderator Temperature Coefficient (MTC) is MORE POSITIVE at lower power; therefore, the expected heat addition INCREASES reactor power.

Explanation: Ans. B is plausible due to the high boron concentration at BOL. Ans. A. is plausible since candidate may believe that higher pressures constitute higher temperatures, however pressure is a constant. Ans. D is plausible since there is an increased amount of burnable poisons at BOL, but it does not affect clad temperatures. Ans. C is the correct answer due to the fact that a positive MTC adds more reactivity as temperature is increased at BOL.

A Reactor Coolant System LOCA is in progress. Containment radiation levels are 110 R/HR.

Which of the following alarms will be generated by CHARMS on the Main Control Board?

A. PROCESS RAD HI HI only B. PROCESS RAD HI HI and CTMT RAD HIGH C. AREA RAD HI HI only D. AREA RAD HI HI and CTMT RAD HIGH Proposed Answer: B, PROCESS RAD HI HI and CTMT RAD HIGH Explanation: Ans. A Incorrect - CHARMS is an area radiation monitor but inputs to the PROCESS RAD Hi Hi annunciator on reaching the 100 R/HR level. This is a plausible distracter because CHARMS also activates annunciator, CTMT RAD HIGH, if readings reach 100 R/hr. Ans. B Correct - CHARMS is an area radiation monitor but inputs to the PROCESS RAD HiHi and CTMT RAD HIGH annunciators on reaching the ALARM level. Ans. C Incorrect - CHARMS is an area radiation monitor but inputs to the PROCESS RAD HiHi annunciator on reaching the ALARM level. This is a plausible distracter because it alarms as a process monitor but is actually an area monitor and confusion can exist on which annunciator is activated. Ans. D Incorrect CHARMS is an area radiation monitor but inputs to the PROCESS RAD HiHi annunciator on reaching the ALARM level. This is a plausible distracter since these are area monitors.

The Plant is in Mode 6 and the following conditions exist:

"* RCS Level (Loop 1) NR Cold Calibration (BB LI-53B/ BB LI-54B) reads 21 inches

"* Reactor Vessel Head installed

"* Maintenance has removed "A" crossover leg nozzle dam for repair due to leakage

"* All other Nozzle Dams installed A loss of all Residual Heat Removal (RHR) occurred and the crew enters OFN EJ-0 15, LOSS OF SHUTDOWN COOLING.

What is the effect on the fuel/core?

A. Any SI pump flow to the RCS would spill out the manway preventing adequate core cooling.

B. A loss of reactor coolant through low pressure letdown to the VCT will result in uncovering the fuel.

C. A pressure increase due to the heat up will push RCS through the manway, uncovering the fuel.

D. Boiling reduces RCS inventory and reflux cooling provided by S/G WR level will limit core uncovery.

Proposed Answer: C, A pressure increase due to the heat up will push RCS through the manway, uncovering the fuel.

Explanation: Ans. A will occur but makeup is not the concern, the loss of vessel coolant from the manway and core uncovery is the problem. Ans. B will not lead to core uncovery as low pressure letdown requires RHR pump head to work. Ans. C is correct per the GEN 00-008 procedure. Ans. D is incorrect because the pathway to the S/G is blocked by the nozzle dams.

0 The Unit is at 100% power.

0 NI 44 fails high.

0 All applicable bistables are tripped per Technical Specifications requirements.

0 Pressurizer Pressure Channel BB PT-456 fails low.

What would be the plant response?

A. PORV Block Valve BB HV8000B would fail close.

B. The reactor would trip on 2/4 OT AT.

C. The reactor would trip on 2/4 OP AT.

D. There is no effect unless BB PT-456 is selected.

Proposed Answer: B, The reactor would trip on 2/4 OT AT.

Explanation: The OT AT trip setpoint lowers as pressure drops below the 2235 psig. Therefore, if the pressure drops in one channel and the NI fails high on another a 2/4 coincidence occurs giving a trip. Ans. C is incorrect since OP AT trip setpoint has no adjustment for A flux, therefore the loss of NI would not affect the setpoint. Ans. A is incorrect because a single channel failure will not close the block valves. Ans. D is incorrect because the pressure channel can't be deselected from the Loop 2 OTAT trips.

  • A large break LOCA with CSAS has since occurred.
  • Alarm ALR 00-048C, SPRAY ADD TK LEV LO has actuated.

What effect will these conditions have on the ability to CLOSE the Sodium Hydroxide Isolation to the Containment Spray Additive Tank valves, EN HV- 15 and EN HV- 16?

A. Only EN HV-15 can be closed.

B. Only EN HV-16 can be closed.

C. Neither valve, EN HV-15 nor EN HV-16, can be closed.

D. Both valves, EN HV-15 and EN HV-16, can be closed.

Proposed Answer: D, Both valves, EN HV-15 and EN HV-16, can be closed.

Explanation: The logic to close HV-15 and 16 is a 1/2 from the two level transmitters. Both valves can be closed without resetting the CSAS when one level is less than 16%. The CSAS would only have to be reset if both levels remained above 16%.

The reactor has just tripped from 100% power and the Main Steamline Isolation valves have been closed. The Atmospheric Relief Valve on the "B" Steam Generator (S/G) Main Steamline has failed and will not open regardless of controller position or S/G pressure.

How will this affect the subsequent cooldown?

A. The safety valve on the "B" S/G Main Steamline will lift to limit pressure in the "B" S/G.

B. A plant cooldown is limited to 50 °F/hr because only three S/G ARVs would be available.

C. A plant cooldown could still be done, but the pressure change in "B" S/G would lag the other S/Gs.

D. The Main Steamline Isolation valves would have to be opened before attempting a cooldown to prevent an SI signal.

Proposed Answer: C, A plant cooldown could still be done, but the pressure change in "B" S/G would lag the other S/Gs.

Explanation: Ans. A is incorrect as the pressure is controlled by Tavg and would not get to the safety valve as other ARVs would work. Ans. B is incorrect since one ARV will permit a 500 F/hr cooldown so three would allow a rate up to 150°F/hr. Ans. C is correct as the pressure in "B" S/G would be slow to react during the cooldown. Ans. D is incorrect as one S/G pressure higher than the others will not cause an SI signal.

B. Steam generator level will decrease and stabilize at a level below 50% narrow range.

C. The feedwater pump speed will decrease to attempt to match the actual measured delta P to program.

D. The feedwater pump speed will increase to attempt to restore proper differential pressure.

Proposed Answer: C, The feedwater pump speed will decrease to attempt to match the actual measured delta P to program.

Explanation: Ans. A is incorrect since level will initially trend down not up as stated. Ans. B is incorrect as level will restore to 50% if enough feed flow is available, but FWIVs will open to maintain levlels. Ans. C is correct since the header pressure failure will cause a reduction in speed due to the reduction in AP across the S/G due to the failed instrument. Ans.

The unit has just tripped due to a LOCA and all Emergency Safety Function (ESF) equipment has started as expected.

You notice that alarm 048A, SPRAY PUMP TROUBLE has annunciated but both Spray pumps are still running.

You check both Spray Pump's running current on the NPIS computer and determine that the "A" Spray pump current is about 15% higher than the "B" Spray pump and Containment pressure is still greater than 30 psig.

You, as the Reactor Operator, should take which of the following actions?

A. Immediately trip the "A" Spray pump as it should have tripped on overcurrent.

B. Inform the Shift Manager and only trip the pump with their approval.

C. Trip the "A" Spray pump as soon as Containment Pressure decreases to 26 psig.

D. If all Containment Fan Coolers are operating, immediately trip the "A" Containment Spray pump.

Proposed Answer: B, Inform the Shift Manager and only trip the pump with their approval.

Explanation: The alarm actuates at 115% of normal current, but does not cause a pump trip.

Justification is you do not secure ECCS equipment without Shift Manager approval in this case.

Therefore, Ans. A is incorrect as it should not have tripped on overcurrent. Ans. B is correct since the pump should be tripped at the discretion of the Shift Manager. Ans. C & D may seem reasonable for the current conditions, but tripping the Spray pump still needs to have Shift Manager approval and there is no procedural guidance to support either one.

The unit has just entered Mode 3 due to a tube leak on the "A" Steam Generator (S/G) and you are isolating the Steam Generator (S/G) using OFN BB-07A, Steam Generator Tube Leakage.

While performing the procedure you are unable to isolate the Main Steam Isolation Valves on the "A" Steam Generator (S/G).

Which of the following actions are required?

A. Close All Main Steam Line Isolation, Bypass and Drain valves on the intact Steam Generators.

B. Actuate a Main Steam Line Isolation Signal from the Main Control Board.

C. Fill the "A" Steam Generator to 80% to 90% to reduce the radiation release.

D. Open "A" Steam Generator Atmospheric Relief Valve to initiate a cooldown.

Proposed Answer: A, Close Main steamline, bypass and drain valves on the intact Steam Generators.

Explanation: The main idea of this question is to ensure the intact steam generators are isolated if the faulted steam generator cannot be isolated in order to prevent cross contamination. Ans. A is correct, since isolating the intact steam generators is the procedurally correct thing to do. Ans.

B is incorrect, since we are in procedure OFN BB-07A and Mode 3, so an orderly shutdown is occurring. Also, MSLI is not even listed in this procedure though one may think it would be a useful method of getting the main steam isolations closed. Ans. C is incorrect, but may be picked since filling a ruptured S/G may reduce dose, but procedurally this is listed as 40-60%. Ans. D is incorrect since the procedure has you isolate ARVs vs. opening them to prevent a radioactive release to atmosphere, but a cooldown is required by other means.

Initial conditions:

  • Train B outage in progress

"* "B" CCP tagged out "B"

' ESW pump tagged out

"* "B" SI pump tagged out A Station Blackout occurs. Power becomes available from the West Bus.

Which electrical lineup(s) should be placed in service?

A. NB02 through the normal feeder breaker.

B. NBO 1 through the alternate feeder breaker.

C. NB02 through the alternate feeder breaker and NBO1 though the normal feeder breaker.

D. Energize PA02 from the normal feeder breaker.

Proposed Answer: B, NBO 1 through the alternate feeder breaker.

Explanation: Ans. A is incorrect because NB02 does not provide any of the necessary equipment to recover from a station blackout, specifically the CCP for inventory control and the ESW pump for equipment cooling. Ans. B is correct since NBO1 powered from its alternate supply is the correct choice. The pumps needed for recovery are only available from NBO 1. Ans.

C is incorrect, because powering both of the safety busses from one power supply is non conservative. Train separation would not be maintained. This choice is also incorrect in that this alignment is only possible from the east bus. Since it is possible to power both busses from one ESF transformer the answer will discriminate between those that know and those that do not know. Ans. D is incorrect, because powering the PA02 bus does not provide alternate equipment for the recovery process. PAO 1 would have, but the West Bus can only supply PA02 not PAO 1.

A. Stop all running Reactor Coolant Pumps.

B. Verify the Spray Additive Tank is aligned.

C. Ensure Reactor Coolant Pump Seal Injection is available.

D. Open Component Cooling Water Bypass valve to containment.

Proposed Answer: A, Stop all running Reactor Coolant Pumps.

Explanation: Ans. A is correct, because CSAS sprays water on the RCP motors and CISB isolates CCW to the RCPs, in either case the RCP need to be shut down. Ans. B is incorrect but a possible answer since the spray additive tank is required to be used during a CSAS, but all procedures assume it is lined up. Ans. C is incorrect but a possible answer because Seal Injection is needed for continued operation, but since these pumps are shutdown this is not an issue. Ans. D is incorrect but a possible answer since cooling water is lost to the RCPs the operator may think restoring CCW will allow continued RCP operation.

While using the EMG ES-3 1, Post-SGTR Cooldown using Backfill, we are required to refill the ruptured Steam Generator and cool down the RCS.

Why is increased attention given to Shutdown Margin (SDM) during this operation?

A. The cooldown that is performed will add significant positive reactivity.

B. The continuous charging during the plant cooldown will cause boron concentration changes.

C. The backfill process will cause boron concentration reduction.

D. The backfill process will remove water from the primary.

Proposed Answer: C, The backfill process will cause boron concentration reduction.

Explanation: Ans. C is correct since this will reduce the shutdown margin due to dilution of the RCS. Ans. A is incorrect since the cooldown will not add a considerable amount of positive reactivity. Ans. B is incorrect and will actually increase boron concentration, thus increasing SDM.

Ans. D is incorrect and will not reduce SDM as long as flow is going to secondary side.
