level of 11 feet. RCIC would expose exhaust NPSH too but is not a concern due to the volume

of the exhaust. Loss of NPSH is not a concern due to suction from CCST or BOTTOM of Torus.

The SRO directing the QGAs ordered QCOP 0250-02," Bypassing MSIV Group I Isolation from Low Low Reactor Water Level" be performed.

Before any QCOP 0250-02 jumpers could be placed, a GROUP I isolation occurred due to Low Low reactor water level. The NSO assigned

QUESTION Torus Spray was being tested on Unit 1 when a Recirc System leak resulted in a reactor scram

and entry into the QGAs on high Drywell pressure and low RPV level. The NSO established Torus Spray, and Torus Cooling. The MO 1-1001-16A, RHR HX Bypass Valve, is fully closed.

The NSO notes that the maximum RHRSW flow with the MO 1-1001-5A, RHR HX SW Disch

Valve, full open is 2500 gpm at a discharge pressure of 275 psig.

Which action(s) (if any) should be taken to correct the RHRSW System operation?a.Start a 2nd RHRSW Pump.

b.Cross-tie the 'A' and 'B' RHRSW loops.

c.None, adequate RHRSW flow has been achieved.

d.Stop the RHRSW Pump, reverse heat exchanger flow and restart the RHRSW Pump.*ANSWER d.

Presently: - Reactor Water Level is +25" and STEADY. - DW pressure is 4 psig and STEADY.

Which one of the loads listed below will have the greatest impact on the discharge rate of the

b.HPCI Emergency Oil pump c.Main Turbine Emergency Bearing Oil pump.

d.RCIC Barometric Condenser Condensate pump.

ANSWER a.

BANK HIGHER Explanation: At 2.5 psig in the DW, HPCI will receive an autostart signal causing the the HPCI

aux oil pump to start. It is a large load off the DIV I (Unit 1) essential battery. The HPCI EBOP

is a large load on the battery but will not be running. If HPCI had been allowed to autostart

before it was trip-latched the EBOP would be running. The main turbine EBOP will be running

but is a load on the NON-essential 250VDC battery. The RCIC barometric condenser

condensate pump will be running but is a load on the DIV II (Unit 2) battery. Technical

QUESTION Unit 2 is in Mode 1 with suppression pool initial conditions of:

Suppression pool level at 14' 3" Suppression pool average temperature 70 degrees F.

Subsequently, a relief valve begins to leak past its seat. Suppression pool level increases by 0.2 inches/hr and average suppression pool temperature increases at 10 degree F/hr.

Which suppression pool Tech Spec limit will be reached first (level or average temperature)

AND what is the Tech Spec Bases for that high limit?a.High average Torus water temperature limits will be reached first.

Basis: to prevent primary containment pressures and temperatures from

exceeding maximum allowable values during a DBA LOCA.b.High average Torus water temperature limits will be reached first.

Basis: to prevent excessive down-comer loads to cause excessive swell during

relief valve operations during a DBA LOCA.c.High Torus water level limits will be reached first.

Basis: to prevent primary containment pressures and temperatures from

exceeding maximum allowable values during a DBA LOCA. d.High Torus water level limits will be reached first.

Basis: to prevent excessive down-comer loads to cause excessive swell during

QUESTION Unit 2 is starting up in accordance with QCGP 1-1, following a weekend outage. No work was

performed on HPCI, but periodic overspeed testing is scheduled during startup. A Clearance

Order, which was placed to allow the Mechanics to prepare HPCI for the overspeed test, is now

TEMP LIFTED. The Startup schedule indicates that Reactor pressure should be raised to 155

psig for HPCI overspeed testing. Reactor pressure is presently 136 psig, increasing to 155 psig

at 2 psig / minute. The ANSO just brought to your attention, a caution statement in QCGP 1-1:

"IF HPCI / RCIC overspeed testing is to be performed, THEN do NOT allow Reactor pressure to

exceed 150 psig until testing is completed." (1) What Reactor pressure should you direct the ANSO to maintain?

AND (2) What is the basis for the response? (1)(2)a.(1) 142 psig.

(2) The caution statement is correct, BUT HPCI IS ALREADY OPERABLE.b.(1) 155 psig.

(2) The caution statement is correct, BUT HPCI IS ALREADY OPERABLE.c.(1) 142 psig.

(2) The caution statement is correct, HPCI is NOT OPERABLE and MUST BE

MADE OPERABLE before pressure goes above 150 psig.d.(1) 155 psig.

(2) The caution statement does NOT apply in this case because HPCI does NOT

need to be OPERABLE until 12 hours1.388889e-4 days 0.00333 hours 1.984127e-5 weeks 4.566e-6 months AFTER Reactor pressure exceeds 150
