Q

How is P-8 cleared?

A

2/4 PRs > 29%

17
Q

What does P-8 doe?

A

Permits auto block of Rx Trips due to single loop low flow trips AND Turbine trip

18
Q

What conditions make up P-10?

A

2/4 PRs >/= 10%

19
Q

What conditions clears P-10?

A

3/4 PRs < 10%

20
Q

What does P-10 do?

A

Permits manual block of:
1. PR High Flux Trip, Low SP
2. IR Trip
3. IR Rod Stop

Also

  1. Resets P-7
  2. Backup de-energization of SR
21
Q

A

2/3 PRZ Press < 1910#

22
Q

What conditions clear P-11?

A

2/3 PRZ Press >/= 1910#

23
Q

What does P-11 do?

A

Permits manual block of SI on low PRZ Pressure

24
Q

What conditions make up P-12?

A

2/4 Loop Tavg = 541*F

25
Q

What conditions clear P-12?

A

3/4 Loop Tavg > 541*F

26
Q

What is the function of P-12?

A

Allows manual block of SI due to low steam line pressure

With High Steam Flow, gives Main Steamline Isolation

Blocks all Steam Dumps

27
Q

What conditions make up P-13?

A

2/2 Turbine 1st stage pressures < 10%

28
Q

What conditions clear P-13?

30
Q

What conditions clear P-14?

A

2/3 SG NR Levels > 67% in at least 1 SG

31
Q

What does P-14 do?

A

Allows or prevents MFW addition.

To prevent it, FWI initiated and MT and MFPs Trip

32

35
Q

What is C-4?

A

Auto and manual rod stop and initiates turbine runback when 2/4 OP delta T at 3% < trip setpoint

36
Q

What is C-5?

A

Rods Alive

Auto only rod stop when 1/1 turbine impulse pressure (MPC-253) < 15%

37
Q

What is C-11?

A

Rods in Heaven

Auto Rod stop only

When Bank D demand is at 229 Steps

38
Q

What is C-20?

A
