Cond / FW

Question 1

CBP Press Limits

Answer 1

38(28)psig (10 sec) - SL#3
35(25)psig (10 sec) - Pmp Start pressures
34(15)psig (A-40/B-70/C-100) - Pmp Trips

Question 2

RPF Press Limits

Answer 2

225(165)psig (5 sec) - SL#3
207(145)psig (5 sec) - Pmp Start pressure
207(145)psig (A-15/B-25) - Pmp Trips

Question 3

CBP Trips

Answer 3

LESS
Low oil pressure - 5psig (U2 ONLY)
Electrical Fault
Suction valve not FULL Open
Suction pressure low - 34(15)psig (A-40/B-70/C-100)

Question 4

RFP Trips

Answer 4

STROLL
Suction Pressure Low - 207(145) A-15/B-25
Thrust >32mil (+/-)
RWL high - 54(54.5)”
Overspeed - 5900rpm
Low condenser vacuum - 22.3(17)”HgVac & >3500rpm
Low oil pressure - 4psig or Emerg hdr <100#

Question 5

Min Flow Limits for CBP & RFP

Answer 5

CBP

• U2 - 3000-3600 - Fail OPEN on loss Vital AC
• U1 - 8000-9000 - Fail OPEN on loss Vital AC

RFP

• U2 - 3600-4600 (AOV’s) - Both fail OPEN on loss Vital AC
• U1 - 2520-4520 (HOV’s) - A- fails OPEN on loss Vital AC / B-Open on loss of Inst A

Question 6

Flow limit for placing 2nd RFP In-service

Answer 6

Prior to exceeding 7mlb mass

Question 7

Time delay for CBP & CP on a LOCA

Answer 7

50 sec time delay prior to being able to restart

Question 8

Steam supply for Rx Feed Pmps HLV & LLV

Answer 8

MSL used on pump start by MSL - C(B) through HLV. At adequate pressure LLV takes over control and is supplied by MSR crossover piping to LP turbine.

LLV opens full on start and controlled by HLV and then closes down as power is increased

Question 9

RFP Seal Water

Answer 9

• Requires 10”HgVac, 1-CBP, & RFP off turning gear prior to placing in-service
• prevents leakage out into environment

Question 10

RFP Speed setter permissive

Answer 10

> 2100rpm and light on vertical panel illuminates

Controls 0-5800rpm

Question 11

M/A station control

Answer 11

2100-5800rpm

Question 12

Crossflow requirements

Answer 12

Used when >80%
<80% crossflow factor = 1
Limits RTP to <2777MWth

Question 13

Startup Level Control Valve Limits

Answer 13

F111 - Locks up when pressure <50# or signal to valve <10ma(Vital AC)
Bypass valve opened >15% RTP when SULCV full open

Question 14

Long Cycle Clean-up Limitations

Answer 14

U2 - Condensate Pump - 70% open / CBP - 55% open

U1 - Limited by Demin Flow >4000gpm

Question 15

Cond / FW Power Supplies

Answer 15

Condensate/CBP
A/B - 4160-D
C - 4160-C

Question 16

Ppm Start limits

Answer 16

• 2 starts from ambient
• 1 start from rated

Allow 30min RUN or 60min IDLE prior to subsequent starts

Question 17

RFP Power Supplies

Answer 17

• Main AC oil pumps - 600AA for A&B
• Standby AC oil Pumps - A - S035A via 600-B (U1-S030 for Both)
  - B - S035B via 600-A

Therefore Loss 4160-C

• U2 Loss of 2B RFP
• U1 loss of BOTH pumps

Question 18

RFP turning gear requirements

Answer 18

• Before Sealing Steam applied
• Exhaust hood > ambient
• MUST be on gear 2hrs prior to start

Question 19

Hotwell Level Control

Answer 19

-Avg - 56-60” (A-71-75” / B-41-45”)

• Powered by Vital AC (Inst A)
  
  • Loss of power causes Spill/Fill valves to fail CLOSED
• Controller Failure
  
  • Red Fail Lamp, & Defaults to MANUAL
• Loss of Power to Recorder kicks from Avg to A control (B if det lost power)
