QUESTIONS REPORT

for SRO

77. 204000G2.1.2 00 1/2/2/RWCU/BANK-MOD/HIGHER/HT2007-30 l/SRO/BLC/RFA

A leak has developed on the RWCU system. The following conditions currently exist:

RWCU HX room ambient temperature (N016C) 195° F

RWCU HX room ambient temperature (N016D) 195° F

RWCU HX room differential temperature (N022C/N023C) 105°F ~T

RWCU HX room differential temperature (N022D/NO*23D) 105°F ~ T

158' elevation south east area (2D21-K601 B) 1100mR/Hr

Based on these current plant conditions, which ONE of the following choices describes

the required operator actions in accordance with the Secondary Containment Control?

[Reference provided]

A. A reactor shutdown per 34GO-OPS-013 or 34GO-OPS-014 is required.

An immediate reactor scram is currently not re'quired~

B~ An immediate reactor scram is required.

Emergency depressurization is not required.

C. An immediate reactor scram is required.

Emergency depressurization is required.

D. A reactor shutdown is currently not required.

Operate the HVAC per 34S0-T41-005 and attempt to isolate the RWCU leak.

A. Incorrect because a primary system is discharging into secondary containment and

the differential temperature and area radiation level is greater than max safe. These

conditions require an immediate reactor scram. Plausible if the applicant knows that a

reactor shutdown is required when an area is above max safe and the leak is NOT a

primary system.

B. Correct.

C. Incorrect because an emergency depressurization is not required. Plausible since

the applicant may not know that the two area temps (or two ambient temps) are in the

same area (and therefore do not meet the intent of two areas above max safe.)

D. Incorrect because ventilation systems should NOT be operated when a secondary

containment radiation condition exists. Also incorrect because a reactor scram is

required based on a primary system discharging with one area differential temperature

above max safe. Plausible if applicant interprets the differential temperature as an

ambient temperature.

79. 212000A2.20 00 1/2/1/RPS/NEW/HIGHERJHT2007-30 l/SRO/BLC/RFA

During an outage, maintenance is in progress on seven hydraulic control units'(HCUs)

to replace the scram valve diaphrams. The following conditions currently exist:

Mode switch: REFUEL position, all rods inserted

Discharge volume isolation test switch: ISOLATE position, under clearance

Scram discharge volume high level bypass switch: NORMAL position

Due to a clearance error, one of the HCUs begins to slowly fill the discharge volume as

the mechanics begin working and the following alarm is received:

SCRAM DISCH VOL NOT DRAINED (603-119)

With these current conditions, which ONE of the following describes the operation of

the RPS logic and the technical specification allowan'ces associated with the high level

bypass switch?

At:I A reactor scram has NOT occurred.

Placing the high level bypass switch in the bypass position will PREVENT a scram.

Bypassing this trip does NOT require entering ,.an RPS Instrumentation LCO action.

B. A reactor scram has NOT o*ccurred.

Placing the high level bypass switch in the bypass position will PREVENT a scram.

Bypassing this trip does requires entering an RPS Instrumentation LCO action.

C. A reactor scram has occurred.

If the high level switch had been in the bypass position, the scram would have still

occurred.

Bypassing this trip does NOT require entering an RPS Instrumentation LCO action.

D. A high level scram has occurred.

If the high level switch had been in the bypass position, the scram would have been

PREVENTED.

Bypassing this trip requires entering an RPS Instrumentation LCO action.

QUESTIONS REPORT

for SRO

A. Correct.

B. Incorrect because the bypass switch will work when the mode switch is in Refuel (or

shutdown). Also incorrect because the high level trip is only required in Mode 5 IF a

rod is withdrawn. Plausible if applicant doesn't know that the bypass switch also works

when the mode swtich is in the refuel position (versus only the shutdown position).

C. Incorrect because the not drained alarm comes in at 3 gallons; whereas the high

level trip occurs at 63 gallons, i.e., a scram has not occurred yet. Also incorrect

because the bypass switch will prevent the high level trip when the mode switch is in

Refuel (or shutdown). Plausible if applicant doesn't know alarm setpoint and thinks that

the bypass switch only works when the mode switch is in the shutdown position.

D. Incorrect because the not drained alarm comes in at 3 gallons; whereas the high

level trip occurs at 63 gallons, i.e., a scram has not occurred yet. Also incorrect

because the high level trip is only required in Mode 5 IF a rod is withdrawn. Plausible if

applicant doesn't know alarm setpoint and thinks that this trip feature is required during

mode 5 with all rods inserted.

A complete core offload was performed at the begining of a refueling outage.

Four bundles have just been reloaded around SRM "0" and the prescribed fuel reload

sequence continues by spiralling outward from SRM "D." The operability status of the

remaining SRMs are:

SRM "A" is inoperable; post maintenance testing is in progress

All other SRMs are operable

During the testing on SRM "A", the operator inadvertently withdraws the SRM "c"

detector a small amount and the following alarms are received:

SRM DETECTOR RETRACTED WHEN NOT *PERMITTED (603-222)

ROD OUT BLOCK (603-238)

Which ONE of the following identifies the impact on refueling operations?

A. Core alterations must now be suspended.

B~ Core alterations may continue in the northwest quadrant.

C. Core alterations may continue only in the northeast quadrant.

D. Core alterations may continue anywhere in the core except in the quadrant where

SRM "A" is located.

A. Incorrect because core alterations are allowed in a quadrant without an a9jacent

operable SRM provided that the bundles being spiral reloaded are in a single fueled

region containing an operable SRM. Plausible if applicant does not know that tech

specs allows refueling with only one operable detector.

B. Correct.

C. Incorrect becaus~ the partially withdrawn SRM is inoperable. Plausible if applicant

knows that the single fueled region tech spec LCO provision was exercised to begin the

reload.

has reduced reactor power from rated power over the last several hours. Current plant

conditions are:

285 MW(e)

Condenser vacuum at 25.0 "Hg and steady

The SRO is evaluating whether the current power configuration will facilitate a manual

turbine trip while maintaining the reactor critical.

Which ONE of the following predicts the plant response if the turbine is manually

tripped at this power, including the required procedure to be implemented after the

turbine is manually tripped?

A. Steam flow will be within the capacity of the bypass valves.

Enter 34GO-OPS-005-1, Power Changes, to adjust reactor power if necessary after

the turbine is manually tripped.

B. Steam flow will be within the capacity of the bypass valves.

Unit 2 is starting up and reactor power is 140/0 power. The operator is pulling rods to

achieve 2 bypass valves to roll the turbine.

Due to a previous rod being difficult to move, the CRD drive water pressure had been

temporarily raised to 300 psid and not re-adjusted back down to a normal pressure.

When the operator placed the rod movement control switch to the single notch out

position for the next control rod, the rod quickly moved from position 16 to 22.

(intended position was 18)

Which ONE of the following identifies an expe,cted annunciator that will be received

and the evaluation of this event?

A. ROD OUT BLOCK (603-238)

This is a mispositioned control rod. Tech Spec 3.1.6. Rod Pattern Control has a

A loss of §!! high and low pressure injection has occurred on Unit 2 with the following

conditions:

All rods inserted

Reactor Water Level. -190 inches and decreasing 2"/min

Reactor Pressure 858 psig being controlled by LLS logic

Steam Cooling is in progress

Because of successful maintenance efforts, HPCI has become available and the crew

has just started injecting to the vessel. The current reactor water level is -189 inches

and rising.

Given these conditions, which ONE of the following procedures is required to be

implemented? .

A. CP-2, RPV Flooding

B. CP-1, Steam Cooling

C. CP-1, Emergency Depressurization

D~ RC RPV Control (Non-ATWS)

EOPs require remaining pressurized following a loss of all high and low pressure

injection systems and beginning steam cooling (@ -185") UNTIL an injection system is

regained; then ED. In this case ED'g will eliminate the injection system (HPCI); and

EOPs specifically exempt ED in this situation. The question satisfiesKA because

requires interpretation of RPV water level as it pertains to high reactor pressure, i.e.

being in steam cooling.

A. Incorrect because level instrumentation is available. Plausible because this is,an

override step in the steam cooling procedure.

B. Incorrect because an override step in the steam cooling procedure states that if

reactor water level is increasing, then perform RC/P (non atws). Plausible if the

applicant realizes that level is still less than -185" (entry condition for steam cooling).

C. Incorrect because an override step in the steam cooling procedure states that if any

system is regained then emergency depressurization is required IF level cannot be

restored. Since level is being restored, then emergency depress is not required.
