E-1.1 (SI Termination)

Question 1

E-1.1

What is the SI reinitiation criteria?

If criteria met, how is SI reinitiated?

Answer 1

• RCS subcooling < 20 deg F
• L_pzr not maintain > 12%
• manually start ECCS pumps as neccesary
  
  • if start CCP, align injection
• Go to E-1

Question 2

E-1.1

What parameter(s) must be met after SI is reset to secure the SI pumps?

RHR pumps?

Answer 2

• P_rcs - stable or rising
• P_rcs > 1650 psig
• No SI flow
• any RHR pump running aligned to RWST

Question 3

E-1.1

What are the different procedures that you can transition to from SI Termination?

Answer 3

• E-1.2, Post LOCA c/d (s 3, P_rcs lowering)
  
  • s 6, L_pzr lowering
  • s 7, P_rcs lowering
• E-1, LOCA (s 9, subcooling < 20 deg F)
  
  • s 9, Lpzr < 12%
  • s 32, subcooling/ L_pzr
• E-0.2, end of proc
• L-7, end of proc
• L-5, end of proc

Question 4

E-1.1

What criteria must be met to secure Cnmt Spray (if actuated) in SI term procedure?

Answer 4

• Cnmt Rad monitors NORMAL
  
  • RM-2
  • RM-7
  • RM-30/31
  • PK, Hi Rad & CNMT RAD off
• P_cnmt < 20 psig
