Level RO 000009 Small Break LOCA / 3 Tier # 1 Knowledge of the operational implications Group # 1 of the following concepts as they apply to K/A # 000009, EK1.01 the small break LOCA:
Importance Rating 3.5 EK1.02 Use of steam tables RO Question 1 Given the following conditions:
- 1. RCS pressure is currently 1020 psia and is remaining stable
- 2. Core Exit Thermocouple (CET) Temperature is 532 F
- 3. RCS Temperature is lowering at a rate of 60 degrees per hour
- 4. Steam Generators are at the 60% NR and stable with no Main or Auxiliary Feedwater flow.
- 5. All ECCS equipment is operating as designed ASSUME RCS Pressure Remains stable and no other operator actions are occurring.
The RCS is currently ___(1)___ and the RCS cooldown is being controlled by ____(2)_____.
(1) (2)
A. Saturated, combination of break cooling and steaming the Steam Generators B. Subcooled, combination of break cooling and steaming the Steam Generators C. Saturated, break cooling only D. Subcooled, break cooling only
Proposed Answer: D Explanation (Optional):
Steam Tables with a RCS pressure of 1020 psia the saturation temperature of water is 547 F, therefore the RCS is currently sub-cooled. Given that the steam generators are at their required level & stable and no feed is being supplied it eliminates the possibility that the cooldown is caused by steaming and leaves the only possible choice to be break flow as the cooling mechanism.

Which of the following is the probable cause for the seal leakoff flow being low?
A. High seal water injection temperature B. Loss of seal injection flow C. Excessive #2 seal leakage D. Low VCT Pressure
Proposed Answer: C Explanation (Optional):
A. Incorrect; High seal water injection temperature decreases the density of the leakoff water resulting in a pressure imbalance (higher pressure drop across the inner portion of the ring) that causes the seal to open and pass more flow.
B. Incorrect; Loss of seal injection flow results in warmer liquid from the RCS to leak up and through the seal. The increased leakoff temperature, increases leakoff flow.
C. Correct; Excessive #2 seal leakoff lowers the backpressure on #1 seal causing it to close up and flow to go down.
D. Incorrect; Low VCT pressure results in less back pressure on the #1 seal, therefore a higher #1 seal leakoff flow.

Level RO 000025 Loss of RHR System / 4 Tier # 1 Ability to determine and interpret the Group # 1 following as they apply to the Loss of K/A # 000025, AA2.07 Residual Heat Removal System:
Importance Rating 3.4 AA2.07 Pump cavitation Question 3 The Unit is in Mode 5 mid-Loop Operation with RCS level at +9 inches.
RHR Pump 1A is in service with a flow rate of 3000 gpm.
At 10:00 AM the MAB RPO reports to the Control Room that RHR 1A is making a loud oscillating swishing noise when he was in the area.
The Primary RO then notices that RHR 1A amps are swinging more than normal, and RCS hot leg level is indicating +1.5 inches.
The Unit Supervisor has announced entry into the Loss of Residual Heat Removal Off normal Procedure, 0POP04-RH-0001, Loss of Residual Heat Removal.
The NEXT operator action that the control room operators should take is to ___________.
A. Reduce RHR 1A pump flow to 1000 to 1500 gpm B. Decrease RCS temperature until the noise and amperage oscillations stop C. Stop RHR 1A and Start RHR1B D. Reduce RHR 1A pump flow to < 1000 gpm
Proposed Answer: A Explanation (Optional):
A. Correct - With RCS NR Hot Leg Level at >1 inch, procedure direction is to reduce RHR flow within limit per Addendum 2 (1000 to 1500 qpm). This range should eliminate cavitation at the given level.
B. Incorrect - This choice is not procedure based and would not help to correct the problem.
C. Incorrect - Starting an additional RHR pump when you have indications of cavitation would not be the correct action. Plus the procedure requires a level of
+6 inches prior to attempting a start or restart of an RHR Pump.
D. Incorrect - Reducing RHR flow to < 1000 gpm would risk an RHR Pump trip on low flow. (925 gpm)

Major Steam Line Break (continued)
Types of Accidents Analyzed The following cases have been analyzed in determining the core power and RCS transients:
- Complete severance of a pipe, with the plant initially at no-load conditions, full reactor coolant flow and offsite power available.
- The previous case with loss of offsite power (LOOP) simultaneous with the steam line break and initiation of the SI signal.
LOOP results in reactor coolant pump (RCP) coastdown.
Since the SGs are provided with integral flow restrictors with a 1.4 ft2 throat area, any rupture with a break area greater than 1.4 ft2, regardless of location, would have the same effect on the NSSS as the 1.4 ft2 break.
Assumptions UFSAR Figure 15.1-11 Assumptions used in the analysis are shown below.
Assumption Description Initial/Nominal Initial reactor power, T ave , and RCS pressure are assumed to be Conditions at their hot-shutdown nominal values.
- The reactor is shutdown with all rods inserted except for the most reactive RCCA which is stuck in the full out position.

Importance Rating 3.6 AA1.06 Safety injection pump Question 11 Given the following plant conditions:
- The plant was at full power when a loss of offsite power occurs
- Pressurizer pressure is 1850 psig
- Containment Pressure is 8 psig
- Offsite power has not been restored
- Emergency Diesels have just received there start signal For the above conditions, which one of the following actions will automatically occur?
A. HHSI pumps start 11 seconds after the Emergency Diesels have received there start signal B. HHSI pumps start 7 seconds after ESF Busses are energized C. HHSI pumps start ~ 17 seconds after the ESF busses are re-energized D. HHSI pumps start 6 seconds after the Emergency Diesel generators receive there start signal
Proposed Answer: B Explanation (Optional):
A. Incorrect, with a loss of offsite power all loads on the ESF busses will load shed and the diesel generator will re-energize the bus within ~10 seconds of the actuation. Mode III load sequence will begin 1 second after the diesel generator breakers have closed in repowering the bus. The HHSI pumps will start ~ 6 seconds later B. Correct, once the ESF bus is re-energized there is a 1 second delay for the mode III sequence to begin and the HHSI pumps will start 6 seconds later or 7 seconds after the ESF bus is re-energized.
C. Incorrect, once the ESF busses are energized (takes 10 seconds) an additional one second mode III sequence occurs and then the HHSI pumps will start in 6 seconds, (Total of 17 seconds to start the HHSU pumps from the time that the Emergency Diesels receive the start signal to re-energize the bus)
D. Incorrect, this is plausible because there is a 6 second delay after the mode III sequence has started to start the HHSI pumps, however the 6 seconds is after the bus has been re-energized and the mode III load sequence has started.

- Unit 1 is performing a Mode 3 cooldown
- RCS is at 520 °F and 1800 psig
- A loss of power occurs on 120 VAC vital distribution panel DP- 1201
- The crew enters 0POP04-VA-0001, Loss of 120 VAC Class Vital Distribution
- A Plant Operator is directed to locally open the 1A SG PORV for temperature control 0POP04-VA-0001, cautions the Plant Operator to NOT open the SG PORV more than 50%.
Which ONE of the following is the reason for this caution?
A. Prevent excessive cooldown with limited RCS instrumentation available.
B. Minimize the mass loss out of the 1A SG with limited AFW capability.
C. Ensure the ability to reclose the 1A SG PORV following opening.
D. Limit the amount of positive reactivity due to cooldown.
Proposed Answer: C Explanation (Optional):
A. INCORRECT - Not the correct basis for the SG PORV stroke limit. Some RCS instrumentation will be de-energized, but not to the extent that monitoring capabilities will be jeopardized.
B. INCORRECT - Not the correct basis for the SG PORV stroke limit. Automatic control of the AFW regulating valve will be lost, but manual control is still available.
C. CORRECT - This is the correct basis for the SG PORV stroke limit. There is only sufficient stored energy in the SG PORV accumulators for only one and one half full strokes of the valve. The caution limits the stroke of the SG PORV to ensure that the valve can be closed.
D. INCORRECT - Not the correct basis for the SG PORV stroke limit. A low steam line pressure SI exists, but under the given conditions it would have already been blocked by procedure.

Distractor B and D do not go together as you can exceed your personnel dose limit and not exceed the airborne limits, and airborne limits can be exceeded without exceeding the dose limit Candidates must understand that when operating these portions of the LWPS the potential for contamination of non-radioactive systems exist. Several years ago contamination of a clean system actually occurred at STP, while operating the LWPS a improper valve lineup caused contamination of the Aux Steam System.
0POP02-WL-0003 Rev 11 4.0 Notes and Precautions 4.1 The maximum allowed filter differential pressure is 35 psid.
4.2 Changes in flow rates or pressures SHOULD be performed gradually to prevent filter damage.
4.3 Any activity that requires entry or access to a Radiologically Controlled Area (RCA), requires a Radiation Work Permit.
4.4 Improper performance of steps in this procedure could result in cross-contamination of non-contaminated systems (Reference 2.2.4).
4.5 The normal demineralizer alignment is LWPS Aux Demin upstream and WE Cond Demin downstream.

AK1.02 Biological effects on humans of the various types of radiation, exposure levels that are acceptable for personnel in a nuclear reactor power plant; the units used for radiation intensity measurements and for radiation exposure levels.
Question 24 An accidental leak in the waste gas system has occurred. Two operators are required to enter an area of the plant to isolate the waste gas leak. RP has determined that the area the team will be in is considered a high airborne area with an airborne concentration of 1 DAC/HR. The general area that the team will be in is 50 mrem/hr.
It will take the team 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to complete the necessary valve alignments to properly isolate the leak. What is the CEDE that the two workers will receive for the task and what is the likely biological effects of this entry?
A. 210 mrem CEDE, some small increase in the probability in biological both Stochastic and Non-Stochastic effects.
B. 204 mrem CEDE, some small increase in the probability in biological both Stochastic and Non-Stochastic effects.
C. 210 mrem CEDE, significant increase in the probability in biological both Stochastic and Non-Stochastic effects D. 204 mrem CEDE, significant increase in the probability in biological both Stochastic and Non-Stochastic effects
Proposed Answer: A Explanation (Optional):
A. Correct, general area equals 50 mrem/hr with 4 man hours in exposed area equals 200 mrem exposure, 1 DAC equals an exposure of 2.5 mren/hr with 4 manhours of exposure equals 10 mrem. Therefore by summing the exposure received 210 mrem is received by the team. An exposure of 210 mrem is below the occupational limits and while all radiation exposure has some potential to raise the probability of biological effects it should be minimal.
B. Incorrect see A above, the 204 mrem is plausible if the candidate assumed that 1 DAC/hr is equivalent to 1 mrem per hour.

Proposed Answer: B Explanation (Optional):
A. Incorrect; each train receives a single level input and with an SI present should initiate and Auto Recirculation for its train. As presented RWST Train A level (LI-931) should have caused auto swap over (75,000 gallons); Trains B & C did by inference and LI-932 indicates higher than LI-931 B. Correct; this lampbox should come on with SI present and remain on until SI is reset and the SI AUTO RECIRC TRAIN A RESET pushbutton is depressed. There are no procedural actions in EO00 or EO10 to have reset Auto Recirculation. Indicates malfunction of SSPS Train A actuation output which will prevent auto swap over on lo-lo RWST level.
C. Incorrect; MOV-0001A Bypass/Inop (due to loss of control power or not fully open) does not prevent auto swap over operation from occurring.
D. Incorrect; Each SI pump has two recirc valves in series. The interlocking scheme for Auto Recirculation to occur requires 1/2 of the valves to go closed for each pump in a train to close. Therefore this condition would not prevent the swap from occurring.

Question 50 Unit 2 was operating at 100% power when a Unit Trip occurs due to a large break loss of coolant accident inside containment. Containment pressure has exceeded 15 psig. All of the ECCS equipment has operated as designed.
Subsequently:
- RWST level has lowered to 75,000 gallons (14%).
- Auto swap over initiated.
- ALL valves repositioned as expected with the exception of the Mini flow recirculation valves on Train A HHSI and LHSI pumps.
- Operators closed ALL the RWST suction valves per 0POP05-EO-ES13, Transfer to Cold Leg Recirculation.
What is the plant response to this configuration?
Containment water levels will A. continue to rise as the remaining water in the RWST drains into the sump due to the Train A Mini Flow Recirculation valve position.
B. lower due to the recirculation of the water back into the RCS and the RWST will remain at a constant level.
C. remain constant and the RWST level will lower as water is being removed from the tank due to the Train A HHSI and LHSI pumps still removing water via the Train A Mini Flow Recirculation valves.
D. lower slowly and the RWST level will rise due to Train A Mini Flow Recirculation valve position.
Proposed Answer: D Explanation (Optional):
A. Incorrect, the mini flow valves will cause some of the water in the sump to be diverted into the RWST B. Incorrect, the containment sump level will lower but not due to the water being diverted to the RCS C. Incorrect, RWST level will actually rise, no suction source is available to the ECCS pumps from the RWST D. Correct, the ECCS pumps will divert a portion of the flow from the sump to the RWST.

A2.08 Consequences of opening/closing breaker between buses (VARS, out-of-phase, voltage)
Question 52 Given the following conditions:
- Emergency Diesel Generator (EDG) 12 is being paralleled to Train B Bus.
- Emergency Diesel Generator output breaker is closed with EDG voltage slightly less than the Train B Bus.
Which of the following:
- 1) Identifies the impact on the Emergency Diesel if voltage remains less than the Train B Bus?
- 2) What action should be taken?
A. 1) EDG VAR meter will move in the negative (-) VAR (LEAD-IN) direction.
- 2) Place the Generator Voltage Adjust Switch in the RAISE position to ensure a slightly positive VAR load.
B. 1) EDG VAR meter will move in the positive (+) VAR (LAG-OUT) direction.
- 2) Place the Generator Voltage Adjust Switch in the LOWER position to ensure a slightly positive VAR load.
C. 1) EDG VAR meter will move in the negative (-) VAR (LEAD-IN) direction.
- 2) Place the Generator Voltage Adjust Switch in the LOWER position to ensure a slightly positive VAR load.
D. 1) EDG VAR meter will move in the positive (+) VAR (LAG-OUT) direction.
- 2) Place the Generator Voltage Adjust Switch in the RAISE position to ensure a slightly positive VAR load.
Proposed Answer: A Explanation (Optional):
A. CORRECT. With EDG voltage less than bus voltage when the breaker is closed, a negative VAR load will be absorbed into the Emergency Diesel Generator. The Generator Voltage Adjust Switch is placed in RAISE to increase generator terminal voltage and zero out the VAR load.
B. INCORRECT. Plausible because this would be the correct action if generator voltage were higher than Safeguards Bus voltage when the breaker was closed and it was desired to zero out the VAR load.
C. INCORRECT. Plausible because the VAR meter will move in the negative direction, however, placing the Generator Voltage Adjust Switch in lower will cause more VARs to be absorbed into the Generator.
D. INCORRECT. Plausible because the action is correct, however, positive VARs would only be created if EDG voltage were higher than Safeguards Bus voltage when the breaker was closed.

From USFAR 3.1.2.6.2.2 Spent Fuel Handling and Storage - Evaluation Against Criterion 61 - Irradiated fuel is stored underwater in spent fuel storage racks located at the bottom of the spent fuel pool.
Spent fuel pool water is circulated through the Spent Fuel Pool Cooling and Cleanup System (SFPCCS) to maintain fuel pool water temperature, purity, water clarity, and water level. The spent fuel storage racks preclude accidental criticality (see Evaluation Against Criterion 62).
Reliable decay heat removal is provided by the closed-loop SFPCCS, which consists of two cooling trains, two purification trains, a surface skimmer loop, and required piping, valves and instrumentation. Water is drawn from the spent fuel pool by the spent fuel pool pumps, is pumped through the tube side of the heat exchangers and is returned. Each suction line, which is protected by a strainer, is located at an elevation 4 ft below the normal water level, while the return line terminates in a sparger pipe at the bottom of the Spent Fuel Pool and contains an
antisiphon hole near the surface of the water to prevent gravity drainage. The SFPCCS is designed to remove the amount of decay heat produced by the number of spent fuel assemblies that are stored following refueling. Each train is capable of removing 100 percent of the normal maximum design heat load and 50 percent of the abnormal maximum design heat load. Table 9.1-1 gives the peak SFP temperatures calculated for various fuel heat load and SFP cooling configurations. System piping is arranged so that failure of any pipeline cannot drain the spent fuel pool or the in-Containment temporary storage area below a depth of approximately 23 ft of water over the top of the stored spent fuel assemblies. A minimum depth of approximately 13 ft of water over the top of an array of 193 (full core) assemblies with 42 hours4.861111e-4 days <br />0.0117 hours <br />6.944444e-5 weeks <br />1.5981e-5 months <br /> of decay is required to limit radiation from the assemblies to 2.5 mR/hr. or less.

Feedwater flow to C Steam Generator will A. rise until a feedwater isolation will occurs.
B. lower until the reactor trips on Lo-Lo Steam Generator Level.
C. initially rise, then will lower resulting in a steam generator level stabilizing higher than before.
D. initially lower, then will rise resulting in a steam generator level stabilizing lower than before.
Proposed Answer: A Explanation (Optional):
A. CORRECT. A level error output signal is produced (176.25%), that now causes the MFRV to open. The increased flow produces a flow error, but it cannot overcome the level error output signal. Therefore the level continues to increase until a Feedwater Isolation Actuation occurs (2/4 S/G levels > 87.5%).
B. INCORRECT. Steam Generator Level increases in this failure, not decreases.
C. INCORRECT: FW flow will increase as indicated, but will not go back down because the controlling channel is failed low and will not change with actual level.
D. INCORRECT. When the controlling channel fails to 0% a level error is created that indicates the actual level is too low. This causes the MFRV to open, increasing FW flow, not decreasing it as indicated.

- RCS pressure 1450 psig and STABLE
- Core Exit TCs are 555°F
- Pressurizer level is 48% and INCREASING
- Containment pressure is 6.5 psig
- SG NR levels are: 35%, 35%, 33%, 36%
- Total AFW flow is 400 gpm The Unit Supervisor is at Step 15 of 0POP05-EO-EO10, Loss of Reactor or Secondary Coolant, and is evaluating whether Safety Injection should be terminated.
Which of the following operator actions is procedurally required for the above conditions?
A. SI termination criteria is met only if AFW flow is adjusted to > 576 gpm. Do NOT transition to 0POP05-EO-ES11, SI Termination, until AFW flow is adjusted.
B. SI termination criteria is met only if the level in C Steam Generator is increased to 34%.
Do NOT transition to 0POP05-EO-ES11, SI Termination, C Steam Generator level is increased to 34%.
C. SI termination criteria is NOT met since pressurizer level is still low and further actions in 0POP05-EO-EO10 need to be performed.
D. SI termination criteria is NOT met since RCS subcooling is less than the required value and further actions in 0POP05-EO-EO10 need to be performed.
Proposed Answer: D Explanation (Optional):
Since containment pressure is greater than 5 psig, adverse containment conditions exist.
A. INCORRECT. AFW flow greater than 576 gpm is a condition to satisfy secondary heat sink, however, since at least 1 steam generator narrow range level is greater than 34%,
secondary heat sink is satisfied.
B. INCORRECT. In order for the secondary heat sink to be satisfied, at least 1 steam generator narrow range level must be greater than 34%, not in all steam generators, thus the secondary heat sink is satisfied.
C. INCORRECT. Pressurizer level must be greater than 44% to satisfy the SI termination criteria, which is satisfied.
D. CORRECT. Saturation temperature at 1450 psig (1465 psia) is approximately 593°F, resulting in RCS subcooling of approximately 38°F. In order to satisfy SI termination criteria in adverse containment, RCS subcooling must be greater than 45°F Technical Reference(s): 0POP05-EO-EO10, Loss of Reactor or Secondary Coolant, Rec 22 Proposed references to be provided to applicants during examination: Steam Tables Learning Objective: (As available)

Importance Rating 4.7 EA2.01 Actions to be taken, based on RCS temperature and pressure - saturated and superheated Question 77 You are the Control Room Supervisor on Unit 2
- A LOCA has occurred on Unit 2
- RCS pressured has lowered to 1420 psig and stabilized
- HHSI pumps are operating
- RCPs have not yet been secured.
- You have reached step 10 of 0POP05-E0-E000, Rx Trip or Safety Injection.
What is the basis for verifying that at least 1 HHSI pump is running and RCS pressure below 1430 psig?
A. Securing the RCPs without at least 1 HHSI pump operating can cause an ICC condition, below 1430 PSIG RCP operation is not required for cool down in any circumstance.
B. At least one HHSI pump is required when RCPs are secured to minimize potential thermal shock if HHSI pumps are started after RCPs are secured, 1430 psig is based on SBLOCA where a loss of the RCP later would result in core uncovery C. Securing the RCPs without at least 1 HHSI pump operating can cause an ICC condition, 1430 psig is based on a SBLOCA where a loss of the RCP later would result in core uncovery D. At least one HHSI pump is required when RCPs are secured to minimize potential thermal shock if HHSI pumps are started after RCPs are secured, below 1430 PSIG RCP operation is not required for cool down in any circumstance.
Proposed Answer: C Explanation (Optional):
RCP trip criteria is based on certain small break LOCA conditions where excessive depletion of RCS water inventory (due to running RCPs) through the break might lead to severe core uncovery if the RCPs were tripped for some reason later in the accident.
The setpoint is selected such that RCPs will be tripped for those conditions which require tripping RCPs, but will not be tripped for those conditions which would have enhanced recoveries if the RCPs remained running, i.e., SGTRs including the DBA tube rupture.
The requirement for having at least one HHSI pump running (and capable of delivering flow to the RCS) prior to tripping the RCPs is based on:
Analysis has shown that if the SI system is not in operation, operation of the RCPs will allow the RCS to be safely depressurized to the point where the accumulators and the LHSI pump can ensure core heat removal before symptoms of Inadequate Core Cooling (ICC) are exhibited. If the RCPs are then tripped during RCS depressurization because of a LOOP or other support condition, the depressurization rate can be increased to maximum to obtain the benefits of the accumulators and LHSI pumps sooner.

C. Lube Oil Cooler resulting in exceeding the maximum bearing temperature limits causing pump bearing damage.
D. Lube Oil Cooler resulting in a breakdown of electrical insulation and shorting of the motor.
Proposed Answer: B Explanation (Optional):
A. INCORRECT. Plausible because the student has to know that the Supplementary Cooler only cools the air in the CCP room and not directly the bearings.
B. CORRECT. Loss of cooling to the Supplementary Cooler allows extreme heat to build up in the relatively small room causing electrical insulation damage that will short the motor in as little as 4 minutes making it the most limiting event.
C. INCORRECT. Plausible because this is a limiting event but it takes about 8 minutes so it is not the most limiting event.
D. INCORRECT. Plausible because some large motors do have lube oil coolers that directly cool the motor oil such as the RCPs which in turn could cause electrical insulation damage if cooling was lost. But the CCP lube oil coolers only directly cool the pump bearing oil.

Question 92 The reactor is at full power.
A surveillance test was completed on PT-456, showing a safety injection action signal occurs at a setpoint of 1854 psig.
Pressurizer pressure instrument PT-455 just failed low and actions have been completed in response to the failure.
ESFAS pressurizer pressure Channel II is ___(1)___. Technical Specification 3.3.2 required action for the above condition is to ____(2)_____.
A. (1) Operable; (2) Bypass ESFAS pressurizer pressure Channel I within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> B. (1) Operable; (2) Place ESFAS pressurizer pressure Channel I in trip within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> C. (1) Inoperable; (2) Restore at least one of the inoperable ESFAS pressurizer pressure channels to OPERABLE within one hour D. (1) Inoperable; (2) Enter TS. 3.0.3
Proposed Answer: B Explanation: Per the TS surveillance requirement, 1854 psig is in the allowable range, although it is below the trip setpoint value of 1857 psig. This is allowed by action A. on the TS.
Therefore, Channel II is operable, leaving one channel inoperable. Per Action 20, the channel must be placed in trip within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Answer A is plausible because the channel can be bypassed for up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. Answer C is plausible because it is less than the trip setpoint, but is within the allowable range. Also, restoring a channel to operable is a TS action (Action 20A),
but it doesnt apply to this instrument. Answer D is plausible because it is less than the trip setpoint, and would be the correct answer if both channels were inoperable (there is no action statement for more than one inoperable channel for this instrument).
