Q

To Open the CCP or SI pp Suction from the RHR Pumwhat alignment must you have?

A

Can’t supply the CCP or SI pump with water from RHR pump unless you’re on the recirc sump and the SI pump recirc back to the RWST is isolated bc you’d pump your recirc sump to RWST

18
Q

Cold Leg Injection Valves, IMO-51/52/53/54 normal position and purpose

A

Normally open Isolate loop specific injection line

19
Q

IMO-340 East RHR HX to Charging Pumps Suction Supply Normal Position and Purpose?

A

Normally closed Aligns RHR pump discharge to CCP suction header

20
Q

When is IMO-340 East RHR HX to Charging Pumps Suction Supply Open?

A

Open for cold leg recirculation

21
Q

What are the interlocks with IMO-340 East RHR HX to Charging Pumps Suction Supply in order to open this valve ?

A

ICM-305 Recirc Sump Suction must be Opened and have control power IMO-262 OR IMO-263 SI mini flow must have control power and be closed

22
Q

What are Recirc Sump to RHR Suction Valves ICM 305 and 306 Interlocks?

A

Will not open unless RHR Suction from RWST Iso valves are closed (IMO-310 and 320) AND CTS suction from RWST Iso valves (IMO-215 and 225) are closed.

23
Q

What are the interlocks with IMO-350 West RHR HX to Charging Pumps Suction Supply in order to open this valve ?

A

ICM-306 Recirc Sump Suction must be Opened and have control power IMO-262 OR IMO-263 SI mini flow must have control power and be closed

24
Q

What are the interlocks for IMO-330 and 331 RHR to Upper spray header to open?

A

Recirc sump isolation valves ICM-305 and 306 must be open

25
Q

What are the interlocks for IMO-310 and 320 RHR Suction from RWST to open?

A

Recirc sump iso valves ICM-305 and 306 must be closed RHR to upper containment spray IMO-330 and 331must be closed RHR to CCP (IMO-340) and RHR to SI (IMO-350) suction header iso valves must be closed.

26
Q

What is the purpose of the ICM-305 and 306 suction fro, recirc sump interlocks for opening RHR Pump Suction Valves IMO-310/320?

A

prevent draining RWST to recirculation sump

27
Q

What is the purpose of the IMO-330/331 RHR to upper spray interlocks for opening RHR Pump Suction Valves IMO-310/320?

A

prevent pumping RWST to upper spray nozzles before cold leg recirculation properly aligned

28
Q

What is the purpose of the IMO-340/350 interlocks for opening RHR Pump Suction Valves IMO-310/320?

A

prevent aligning CCP/SI pump suctions to recirculation sump

29
Q

What is RC Loop #2 hot leg to RHR Suction IMO-128 interlocked to ?

A

will NOT open if RCS pressure > 411 psig on NPS-122, Loop 1 Ch3

30
Q

What is the RC Loop #2 Hot Leg to RHR Suction IMO-129 interlocked to?

A

will NOT open if RCS pressure > 411 on psig NPS-121, Loop 2 Ch2

31
Q

How does IRV-311 RHR Hx Bypass Valve fail on loss of air?

A

Open

32
Q

How do RHR Hx Outlet valves IRV-310 and 320 fail?

A

Open

33
Q

What is the NORMAL COOLDOWN FLOWPATH for RHR?

A

Suction from Loop 2 Hot Leg Discharges to Loops 2 and 3 Cold Legs via ICM-111 thru both Hx and Hx Bypass

34
Q

What is the ALTERNATE COOLDOWN PATH for RHR?

A

Suction from Loop 2 Hot Leg Discharges to Loops 2 and 3 OR 1 and 4 Cold Legs, NOT using ICM-111 Choice is temperature dependednt

35
Q

Do Cold Leg Loops 1 and 4 have thermal sleeves?

A

NO

36
Q

Do Cold Leg Loops 2 and 3 have thermal sleeves?

A

YES

37
Q

What is the INJECTION FLOWPATH for RHR?

A

Suction from RWST Discharges to Loops 1-4 Cold Legs with all flow thru the Hxs

38
Q

What are the 3 LTOP Protections? 270*F (300*F)

A

RC Loop 2 Hot Leg to RHR Suction safety valve SV-103 2 PZR PORVS >2 inch RCS vent

39
Q

Whate are the interlocks on th Clean and Dirty Waste HUT Inlet Valves?

A

Both cannot be closed at the same time. This ensures you always have a flowpath for drains

40
Q

What is the interlock on Liquid waste to U1/U2 discharge tunnel shuteoff valves RRV-287/286?

A

You cannot open unless at least 1 CW Pump is I/S

41
Q

What is the interlock on the GDT Inlet Valves?

A

Interlocked so that if 1 is open, all the others remain closed

can’t have more than 1 open at a time
