D. will decrease by 7-9 psig ANSWER:

Reference:

Task / Objective: Question Source: Question C GP GFES Chapter 6, 413.00.04 New Difficulty:

Page 75 of 89 Explanation:

As the SP Level Decreases, the HPCS Water Leg Pump suction pressure will decrease. Pump discharge head is directly related to pump suction head. (HP+OUTPIN a OUTPOUT). If suction head decreases, discharge head will decrease corresponding to that amount. Therefore, since there is ~.44 psig/foot in a column of water, if water level drops by 8 feet, C is the correct answer.

The 1B loop temperature should be at near drywell temperature and will remain relatively constant since its suction or discharge isolation valve is closed while in SDC to prevent short cycling the SDC flow, therefore there is no flow in that loop.

2-4200ZC, 1E-2-4221AA/AD 040.00.021 New GP GFE LP #7, pp 32, 33, 43 Explanation:

The equalizing valve isolates the high pressure sensing leg from the low pressure sensing leg. With the valve open, the reference and variable leg pressures would equalize causing the level instrument to indicate higher than actual level.

Following the schematics, on 4200ZC, the N407C Level Transmitter will pevent the N707C Trip Device from ever seeing a low level signal, which will prevent energizing the K707CX Relay. This relay will fail to actuate a contact on 4221AD (3rd Leg from the left). This will prevent energizing the K3 relay, which should close a contact in the K10 logic leg (10th leg from the left). The K10 logic string is a type of 1 out of 2 taken twice. The K2 and K3 contacts are the Low Level Contacts. The K4 and K5 contacts are the High Drywell Pressure contacts. If an actual Level 1 signal existed, the K2 contact would close (from the A logic), but the K3 would not close, therefore not energizing the K10 contact, which ultimately feeds into the pump start logic through the K12 relay.

The pump would, however start on a high drywell pressure signal, or a combination of the A Level and C DW pressure signals.

With the unit a full power for extended period of time, the decay heat rate would be high at the time of the scram. This decay heat would be approximately 7 percent following the scram and at 30 minutes would be 1-2%.

Following the MSIV Isolation, several SRVs would initially open, activating the Lo-Lo Set Logic. Since 1 SRV can pass approximately 7 percent steam flow, once the initial pressure transient is over, one SRV can handle the decay heat load. The S SRV has the lowest LLS Setpoint of 896 to 1006 psig.

• Reactor power is 48%

• ADS has been inhibited and ECCS has been prevented

• ARI has initiated What is (1) the next procedure step required, AND (2) the bases for the action.

B. (1) Runback recirculation flow to minimum per LGA-010, (2) to rapidly reduce reactor power below 3%, thereby eliminating the need to trip the reactor recirculation pumps.

C. (1) Trip the Reactor Recirculation Pumps per LGA-010, (2) to minimize the circulation of boron through the reactor, allowing it to concentrate in the fuel zone.

D. (1) Trip the Reactor Recirculation Pumps per LGA-010, (2) to rapidly reduce reactor power to within the capacity of the turbine bypass valves.

Explanation:

Once ARI is initiated, the next step in the LGA-010 power leg is to run recirc back to minimum. With a High Drywell signal, these valves are locked up and cannot be runback. Therefore the Recirc pumps should be tripped.

Unit 2 is in MODE 4. Average Reactor Coolant temperature is 110°F.

• 2A RHR loop is in the Shutdown Cooling (SDC) Mode of operation.

• 2E12-F004A, RHR Pump Suppression Pool Suction Valve, was vented with Average Reactor Coolant temperature at 120°F.

The LPCI mode of 2A RHR system is A. OPERABLE, provided the system is maintained capable of being realigned when required.

B. NOT affected, since it is NOT required to be operable with the current plant conditions.

C. INOPERABLE, since the minimum flow valve is deenergized closed for SDC Operations.
