Which ONE of the following Emergency Action Levels (EAL) is required, and what is the criterion for that EAL?

It is required to declare an:

_____ A. UNUSUAL EVENT, due a fire inside the PROTECTED AREA.

_____ B. UNUSUAL EVENT, due to Loss of Offsite Power.

_____ C. ALERT, due to Loss of Offsite and Onsite AC Power.

_____ D. ALERT, due to a fire in volving SAFE SHUTDOWN EQUIPMENT.

Correct Answer: D ALERT EAL HA2 is required due to a fire invol ving SAFE SHUTDOWN EQUIPMENT. Candidate must know loss of one bus does not indicate a Loss of Offsite Power, and that Bus 64B is a power source for Safe Shutdown equipment Plausible Distractors: A is plausible; fires on site for 15 minutes requ ire HU 2 Unusual Event. This has been exceeded by HA2. B is plausible; SU1 is not met because SST 64 and 65 are energized.

C is plausible; SA1 is only applicable in Mode 4 and 5.

Reference Documents 23.107 Rev 105 Ability to determine and/or interpret the following as they apply to HIGH REACTOR WATER LEVEL : Swell QUESTION 83 The plant was operating at full pow er, when the following occurred:

BOTH Feedwater Pumps TRIPPED. The reactor automatically scrammed. ONLY ONE Control Rod is at position

48. ALL OTHER Control Rods are FULLY INSERTED. HPCI initiation RAISED RPV Water Level from 110 inches. HPCI was MANUALLY TRIPPED as RPV Water Level reached 210 inches.

Plant conditions are currently:

Reactor pressure 700 psig, rising at 10 psig per minute. MSIVs are OPEN. The OPERATING CRD Pump TRIPPED. What is the expected RPV Water Level response over the next TEN MINUTES, and what action will be required to be directed?

Over the next TEN MINUTES, RPV Water Level will . . .

_____ A. RISE due to SWELL. It is required to direct operators to allow steam off to lower RPV Water Level BELOW 214 inches.

_____ B. LOWER due to SHRINK . It is required to direct operators to use HPCI to maintain RPV Water Level ABOVE 173.4 inches.

_____ C. LOWER due to SHRINK. It is required to direct operators to use ONLY RCIC to maintain RPV Water Level ABOVE 0 inches.

_____ D. RISE due to SWELL. It is required to direct operators to TERMINATE AND PREVENT Injection Systems to lower RPV Water Level BELOW 114 inches.

Correct Answer: A HPCI injected (100 inches x 200 gal per inch=) 20,000 gallons of cold CST water. As this water is heated, SWELL occurs. It is required to maintain RPV Water Level below Level 8 (214 inches). The SRO is required to direct operators to allow steaming to lower RPV Water Level. Shrink cannot occur because heatup and pressurization of saturated system is in progress with NO steam voids. ALL SRVs and TBVs are shut for the next ten minutes because Reactor Pressure will be below 800 psig.

Plausible Distractors: B is plausible; identifies misc onception about shrink and swell. C is plausible; identifies misc onception about shrink and swell. 0 inches is the MINIMUM for the ATWS RPV Water Level Control Band. ATWS is plausible because ONE Control Rod did not fully insert.

D is plausible; 114 inches is the MAXIMUM for the ATWS RPV Water Level Control Band.

ATWS is plausible because ONE Control Rod did not fully insert.

Correct Answer: D Drywell Average Air Temperature exceeds 145F, which is listed in LCO 3.6.1.5 Plausible Distractors: A is plausible; RPV Water Level Instruments can be threatened by High Drywell Temperature in Emergency Conditions.

Given these conditions; (1) Which ONE of the following describes the response of the Automatic Depressurization System (ADS)?

AND (2) What operator actions which should be ordered?

_____ A. (1) ADS will OPEN Safety Relief Valves at 12:20. (2) It is required to INHIBIT ADS prior to automatic actuation and MANUALLY Emergency Depressurize the reactor at a specified RPV Water Level.

_____ B. (1) ADS will OPEN Safety Relief Valves at 12:27. (2) It is required to INHIBIT ADS prior to automatic actuation and MANUALLY Emergency Depressurize the reactor at a specified RPV Water Level.

Operator Challenges involve documentation of work arounds, and do not meet the requirements of Temporary Modification Evaluations.

QUESTION 96 Following a Refueling Outage, the following conditions exist:

ALL RPV Head Closure Bolts are FULLY TENSIONED. Reactor Coolant System Temperature is 185 F. The Reactor Mode Switch is in REFUEL and Control Rod exercising is in progress.

QUESTION 98 During a DECLARED EMERGENCY , a leak develops in an area that is accessible, but now radiologically contaminated. The Shift Manager has directed that an investigation be performed IMMEDIATELY. In accordance with MRP05, ALARA / RWPs, what are the RWP REQUIREMENTS for entry into the area for investigation?

_____ A. A written Specific RWP must be issued.

_____ B. A General RWP already exists for this type of event.

_____ C. A revision to the General RWP for that area must be issued.

_____ D. A verbally issued RWP may be used for timely plant response.

Correct Answer: D A verbally issued RWP may be used for timely plant response.

Plausible Distractors:

A is plausible; but not required under emergency conditions. B is plausible; existing General RWP would not be useful since conditions have changed.

C is plausible; but not required under emergency conditions.

QUESTION 99 While executing 29.100.01 Sheet 1A, ATWS RPV Control, Emergency Depressurization is REQUIRED. Conditions are as follows: Standby Liquid Injection has been INITIATED. RPV Level is -15 inches. Reactor Pressure is 1000 psig. Injection has been Terminated and Prevented as required. FIVE Safety Relief Valves have been OPENED. Reactor Pressure is 850 psig LOWERING. RPV Water Level is -30 inches LOWERING. Which ONE of the following actions is required to be ordered?

_____ A. RAISE RPV Water Level above -25 inches using INSIDE the shroud systems FIRST. _____ B. RAISE RPV Water Level above -25 inches using OUTSIDE the shroud systems FIRST. _____ C. WAIT until RPV Pressure LOWERS to 230 psig, THEN RAISE RPV Water Level above -25 inches using INSIDE the shroud systems FIRST. _____ D. WAIT until RPV Pressure LOWERS to 230 psig, THEN RAISE RPV Water Level above -25 inches using OUTSIDE the shroud systems FIRST. Correct Answer: D with ATWS conditions, ED requires initial pressu re reduction to MSCP without injection. THEN, using OUTSIDE the shroud systems FIRST, RPV Water Level may be restored.

Plausible Distractors: A is plausible; below MINIMUM ATWS Level Control Band. B is plausible; Would be true if reactor was shutdown under all conditions, per RPV Control.

D is plausible; OUTSIDE the shroud sources are required to be used FIRST, then augmented with INSIDE the shroud sources.

QUESTION 100 The plant is operating at full power, when a tr ansient occurs, resulting in the following conditions:

NO Control Rod movement occurred. Blue Scram Valve Lights on the Full Core Display are ALL LIT. The Turbine Generator is ON LINE. Reactor Power is 30%. ADS is INHIBITED. FSQ 1-8 is COMPLETE. RPV Water Level is at 60 inches, LOWERING at 4 inches per minute. Torus Water Temperature is 90 F, due to HPCI starting. Which ONE of the following EOP ACTIONS should have HIGHEST PRIORITY , based on these conditions?

_____ A. Start Torus Cooling per 23.205.

_____ B. Vent the Scram Air Header per 29.ESP.03.

_____ C. Deenergize Scram Solenoids per 29.ESP.03.

_____ D. Defeat RPV Level 1 MSIV Isolation Signals per 29.ESP.11.

Correct Answer: D RPV Level 1 will isolate MSIVs in three minutes. At 30% power, MSIV Closure represents a substantial containment threat.

Plausible Distractors: A is plausible; Torus Cooling is required, but cannot mitigate the heat load of 30% power dumped to the Suppression Pool.

B is plausible; Control Rod in sertion is required. Blue Scram Valve Lights indicate Scram Valves are OPEN and efforts to vent scram air header will be ineffective.

C is plausible; Control Rod in sertion is required. Blue Scram Valve Lights indicate Scram Valves are OPEN and efforts to deenergize scram solenoids will be ineffective.
