Question 4

What are the RESTART Limitations for a CCP Pump?

Answer 4

CCP Pump start limitations are as follows:
• Two starts in succession from ambient temperature. A one hour wait is required before additional start attempts.
• One start at rated temperature (obtained after 30 minute run). A one hour wait is required before additional start attempts.

1B - 14
1C - 15
3A - 13
3B - 14
3C - 15
2A - MCC11
2B - MCC12

Question 6

What actions are taken on a loss of CCP per SOP-13?

Answer 6

• Scram the Reactor
• Trip the Recirc Pumps
• Trip WCS Pumps

Question 7

What are the fail positions of the Temperature Control Valve and the Makeup Water Valve for CCP?

Answer 7

TCV - Max Cooling

M/U - Fails Open

Question 8

What is the CCP flow limit for the WCS NRHX and why? How is this achieved?

Answer 8

1450 gpm limit to prevent cavitation in the HX, this is done by CCP-FV126 controlling bypass flow to maintain 1430 gpm through the HX.

Question 9

What are indications of a WCS NRHX tube leak?

Answer 9

• Rising Expansion Tank Level
• Raising NRHX Outlet Temp
• RE131, WCS Outlet Rad Monitor in alarm

What are the loads on the CCP System?

Answer 10

• WCS NRHX
• RHR Seal Coolers
• Equip Drain Cooler
• Sample Coolers
• WCS Seals
• RDS Pumps
• Drywell Unit Coolers
• RCS Pump Motors and Seals
• CCP Mini Loop/IAS Compressors
