The following plant conditions exist:

- Pressurizer temperature is 588 "F

- Pressurizer level is 285 inches and rising

- RCS Pressure is 1400 psig and lowering

- Quench Tank pressure is 0 psig and stable

- The ERV acoustic monitor indicates flow noise What would be the expected temperature as ~ndlcated on the ERV PSV-1000 Outlet Temp on the Safety Parameter Display System (SPDS)?

A Approx~mately 212 "F

8. Approximately 260 "F C. Approximately 280 "F D. Approximately 588 "F Answer:

6. Approximately 260 "F Notes:

Candidates should be provided with steam tables. The temperature elements on the ERV tailpipe would indicate the temperature for the Quench Tank pressure from the Mollier diagram, therefore, answer (b) is correct since the isenthalpic throttling process will produce a superheated value. The disclaimers are incorrect because: (a) is the saturation temperature for 14.7 psia, (c) is temperature on the saturation line coming straight across the Mollier diagram for 1400 psia and (d) is the saturation temperature of the pressurizer.

Question:

RO:E SRO:

Given the following plant conditions:

- Reactor trip from full power

- Full ES actuation

- ICCMDS Display Subcooling Man~in indicates 0 "F

- ICCMDS CET temperatures are alternating between superheated and saturated conditions All EOP actions have been performed for these conditions.

Which of the following describes the primary mode of RCS cooling for these conditions?

a. Reflux Boiling

b. Forced Convection

c. Natural Circulation

d. Natural Conduction Answer:

a. Reflux Boiling Notes:

Answer (a) is correct since the conditions listed would indicate an ICC event in which boiler condenser cooling would occur (commonly referred to as "reflux boiling" at ANO). (b) is incorrect since RCPs are OFF, (c) is incorrect since SCM is lost, (d) is incorrect because conductive heat transfer would provide minimal heat removal.

During restoration of normal makeup and seal injection, which of the following is true?

a, If PZR level is <55", normal makeup is restored before seal injection

b. If RCP seal bleedoff temperatures are >I80 degrees, seal injection control valve (CV-1207) is quickly opened to establish previous flow rate.

c. If RCP seal bleedoff temperatures are >I80 degrees, CV-1207 is slowly opened to minimize thermal shock to the RCP seals.

d. BWST outlet valve associated with the operating HPI pump must be closed prior to opening CV-1207.

Answer:

c. If RCP seal bleedoff temperatures are >I80 degrees, CV-1207 is slowly opened to minimize thermal shock to the RCP seals.

Notes:

(a) is incorrect. Restoring normal makeup and seal injection has no dependency on the Pressurizer level.

(b) is incorrect. Reestablishing seal injection quickly in any condition has the potential for shocking the RCP seals.

(c) is correct, AS stated above, seal injection must be restored slowly to ensure RCP seals are not damaged.

(d) is incorrect. Restoring normal makeup and seal injection has no dependency on the BWST outlet valve position.

" A and "D" are also followup actions, " D should only be done if " C is unsuccessful. " A is a followup action to verify turbine has tripped but is a lower priority to reactivity.

" B is a method of emergency borating to insert negative reactivity but is slow and thus a lower priority to step "C".

Question:

What would be the effect on the SG pressure and level instruments if a loss of the RS-1 bus occurred?

A. lnstrument power would automatically be transferred to YO-2 by the ABT B. The NNI-X S1 and S2 switches would open and SASS would transfer to NNI-Y.

C. Both NNI-X SG pressure indicators would fail so ICS could not generate a BTU limit alarm.

D. lnstrument power would automatically be transferred to YO-1 by the ABT.

Answer:

A. lnstrument power would automatically be transferred to YO-2 by the ABT Notes:

" A is correct, a loss of RS-1 would simply cause NNI-X to be powered from YO-2, -24vDC logic power is auctioneered and instrument power would transfer by the ABT within 0.5 seconds.

" 6 is incorrect, it would take a loss of both RS-1 and YO-2 to cause the S1 and S2 switches to open.

" C is incorrect, although SG pressure does input to the BTU limit alarm, the NNI-X SG pressure inidcators would not be failed due to the power transfer to YO-2.

" D is incorrect, the alternate power to NNI-Y is from YO-1.

SRO:]

A radioactive gas release of WGDT T-188 has been terminated by Gaseous Radwaste Monitor, RE-4830, in high alarm. Examination of the recorder paper shows RE-4830 had been trending steadily at -2000 cpm when it jumped to 30,000 cpm and then dropped back to -2000 cpm.

What action should be taken?

A. Submit Condition Report and check system alignment.

B. Reset RE-4830 and notify Nuclear Chemistry to perform offsite dose projections via RDACS.

C Isolate T-18B and then re-subm~t sampllng and release permlt D. Reset RE-4830 and re-establish T-188 gaseous release.

Answer:

D. Reset RE-4830 and re-establish T-18B gaseous release Notes:

The indications given are representative of an instantaneous spike, therefore "d" is the correct answer. The other three are actions to be performed if RE-4830 did NOT "spike."

What is the key concern with a DBA occurring while the Reactor Building (RE) is inoperable per Technical Specifications?

A, A large release of radioactivity would cause embrittlement of the steel liner plate B. High temperatures would cause unalyzed stresses on piping within the RB C. High internal pressure would cause greater leakage of radioactivity to atmosphere D. Humidity inside RB would cause RB instrumentation accuracy to be unacceptable.

Notes:

"C" is correct, RB inoperability is based on leakage and leakage in excess of Tech Specs could cause an unacceptable amount of radioactivity to be released due to a larger leak rate from the high internal pressures assumed during a DBA.

" A is incorrect, although radiation does embrittle metal, this is not as significant as leakage.

" 0 is incorrect, although high temperatures will raise stress levels on piping, this is not as significant as leakage.

"D" is incorrect, although humidity can cause instrumentation inaccuracies, specific RB instrumentation is qualified for this environment.

Given:

- LOCA in progress with Degraded Power conditions

- EDG #2 did NOT start

- RCS pressure stabilized at 1750 psig

- RCS leakage calculated to be 210 gpm With these accident conditions, which of the following would pose the greatest challenge to core cooling?

a. RCS leakage increases to 1000 gpm b Both CFT pressures at 560 psig

c. Lockout relay trips on 4160v A3 bus

d. Initial BWST level at 37 ft Answer:

c. Lockout relay trips on 4160v A3 bus

~~

-~

Notes:

Due to the high system pressure, the HPI system is the only system available to keep the core cool. Also, with only one train of ECCS available, if A3 were lost (due to lockout from high current) there wouldn't be any core cooling until the RCS depressurized to CFT pressure and LPI would not be available to cool the core at lower pressures. All of this makes [c] the greatest threat to core cooling.

[a] is incorrect due to ability of CFT's and LPI to cool core. With the larger break the RCS will depressurize, CFT's will dump and LPI will provide -3000 gpm cooling flow.

Id] is incorrect since a BWST level slightly lower than T.S. only means that the ECCS will go on RB sump recirc earlier than if the level was at the minimum T.S. level of 38.4 ft. In addition with only one train of ECCS is operation, the demand on the BWST is lessened.

[b] is incorrect, even if both CFT's do not discharge all of their volume into the RCS, a sizable quantity will be dumped, and LPI is still available to cool core as the RCS is cooled down.

Why are Decay Heat Cooler Outiet Valves SW-22A and SW-226 throttled during normal operation?

a. Service water flow to the Auxiliary Cooling Water System is raised during normal operation.

b. Maintains adequate service water flow to the Reactor Building Coolers when ES actuates.

c. Reactor cool~:~r to serv,ce \\later diiferei?:cal temperature is reduced when ES actiiates

Notes:

a is incorrect, while it is true that ACW demand will be higher during normal operation, this is not the reason forthrottling the DH cooler outlets.

"W is correct, SW flow to the DH coolers are throttle because flow to ES components may not be adequate (in particular RB Coolers are EDG coolers). The valves are marked so that they will not be throttled below the minimum ieyuii-ed for the DH coolers.

8,.

c is incoii-ect because throttling the valves wiil not reduce the service water to RCS differential temperature.

"d" is incorrect because water hammer of service water piping of the DH coolers is not a concern.

"8" is correct since overcooling is evident by RCS pressure and T cold dropping. SCM is adequate and both SGs have >340 gpm flow so EFW should be throttled per RT-5.

"A" is incorrect, this is the "old" minimum EFW flow value.

" C is incorrect, although no RCPs are running, SCM is adequate, therefore the REFLUX BOILING setpoint would be inapproriate.

"D" is incorrect, although overcooling is evident, MSLl is too drastic a measure as SGs are much greater than 600 psig, EFW should be throttled first.

Answer:

Notes:

OTSG fill rate is adjusted so that OTSG levels raise at 2 incheslminute at OTSG pressure of 800 psig and 8 inches/minute at OTSG pressure of 1050 psig. This limits the overcooling effects of feeding OTSGs with EFW. At 885 psig OTSG fill rate will be 4 incheslminute. " b is the correct answer.

Notes:

With LT-1001's reference leg empty, the delta pressure transmitter will sense a minimum DP and max level.

SASS has no effect on PZR level instruments, (b is thus incorrect) therefore the makeup valve, CV-1235, will close due to the indicated high level. Letdown flow will remain constant (making distracter "dm incorrect) and therefore Makeup Tank level will increase as in answer [a].

If the trainee determines indicated PZR level will decrease, then he will probably choose [c].

Answer:

a. Select the NNI-Y signal for RCS loop A hot leg temperature.

~

~~

~-

~

Notes:

Answer [a] is correct, because the annunciator for SASS mismatch points to an instrument failure. The "Feedwater is Rx Limited" annunciator indicates a problem with a false high temperature feeding into the unit Tave since this annunciator alarms when FW is less than demand by 5% or more. This points to a failed high Thot instrument since a failed Tcold instrument would cause the affected loop to be artificially low and the "Feedwater is Rx Limited" annunciator would not be in, Answer [b] is incorrect, due to instrument failure, the controlling Tave would not be selected until lCS components were placed in Manual.

Answer [c] is incorrect, ICS would be trying to raise A FW flow due to the cross limits.

Answer [dl is incorrect, " B T cold is not the problem, the loop with the higher temperature has the failed instrument.

Answer [c] is incorrect. while the hot leg level transmitters have an input to this alarm, a level transmitter failing high would be indicative of no voids and thus the ICC alarm would not be in alarm.

Which of the following statements is correct concerning the Spent Fuel Pool inventory?

a. The SFP will drain to - 2 feet above the spent fuel assemblies.

b. Emergency makeup from service water will be needed to prevent the SFP level from reaching the spent fuel assemblies.

c. The SFP level will stay relatively constant due to siphon holes in the discharge piping.

Notes:

(a,) & (b.) are incorrect. With no operator action at all, the lowest the level would go is -3 feet to the bottom of the suction pipe. This is still - 20 feet above the fuel.

(c.) is correct. The discharge pipe has the siphon break holes located at normal pool level.

(d.) is incorrect. The suction pipe bottom is at -3 feet, however, with the discharge valve closed the pool will stop draining out the break at the normal pool level due to the siphon holes on the discharge pipe.

The dose rate in area of P-114 is 1.8 remlhr.

Your yearly exposure to date is 1.6 rem.

Which one of the following is the LONGEST stay time allowable WITHOUT exceeding Administrative Dose Control Limits (TEDE)?

A 5 mlnutes B 10 mlnutes C. 15 minutes D. 20 minutes Answer:

B. 10 minutes Notes:

The Administrative Dose Control Levei is 2.0 Rem TEDE for the catendar year. With a dose rate of 1.8 Whr a stay time of 10 minutes would result in a dose of 0.3 Rem. The WCO's total accumulated dose would be 1.9 Rem, therefore " B is correct.

Notes:

Answer (d) is correct since the main feedwater block valve closure is inhibited above 80%, once ~ 8 0 %

they will close in fast speed. Answers (a) is incorrect, no bias is applied to demand although it will be maximized due to the high power level and the MFP trip.

Answer (b) is incorrect, a bias of 125 psig is subtracted from the normal setpoint of 2205, the spray valves should open at 2080 psig.

Answer (c) is incorrect, control rods will start to insert but not due to a crosslimit from feedwater, rather the reactor system will be crosslimiting feedwater. A bias subtraction from the reactor demand signal will cause the rods to insert.

Given:

The yellow trouble LED is ON for # I EDG flame detector module on C463 and has been acknowledged on C463.

Subsequently, a # I EDG smoke detector spuriously actuates.

Which of the following annunciators would alarm due to the smoke detector actuation?

a. "FIRE WATER F L O W, K12-A2

b. "FIRE WATER PRESSURE L O W, K12-B1 C "FIRE, K12-A1

Answer:

c. "FIRE". K12-A1 Notes:

The only expected annunciator is (c). The actuation of the smoke detector will cause a FIRE alarm.

" A and "B" are incorrect, the deluge system will not flow water since there is no actual fire to melt the fusible link sprinkler heads.

" D is not correct, a detector actuation will not cause the Trouble annunciator to re-flash.
