BEP-0

Question 1

What is adverse containment?

Answer 1

Containment pressure >=5 psig
or
1AR-20 or 21 >=10^5 R/hr

Question 2

How do we verify reactor tripped?

Answer 2

Rod bottom lights - ALL LIT
Reactor trip and bypass breakers
- OPEN
Neutron flux - DROPPING

Question 3

What do we do if reactor is not tripped?

Answer 3

Manually trip the Reactor:
● 1PM05J
● 1PM06J
IF PR channels are greater
than 5%
OR IR SUR is positive,
THEN GO TO 1BFR-S.1, RESPONSE
TO NUCLEAR POWER
GENERATION/ATWS, Step 1.

Question 4

How do we verify turbine tripped?

Answer 4

All Turbine throttle valves -
CLOSED

All Turbine governor valves -
CLOSED

Question 5

What do we do if turbine not tripped?

Answer 5

Manually trip the turbine:
o Trip pushbutton
o OWS panel G-5512
IF any throttle AND any
governor valve are open,
THEN isolate the steam
supply:
Manually run back the
turbine at maximum rate at
OWS panel G-5501:
o
1) Select turbine MANUAL.
2) Select RAPID.
3) Select and hold GV
lower arrow.
o Manually actuate Main
Steamline Isolation AND
verify MSIV bypass valves
are CLOSED.

Question 6

How do we verify AC busses are energized? What do we do if none are energized? What do we do if only one energized?

Answer 6

ESF busses - AT LEAST ONE
ENERGIZED:
o Bus 141
o Bus 142
a. GO TO 1BCA-0.0, LOSS OF
ALL AC POWER, Step 1.

WHEN time permits,
THEN try to restore power
to deenergized ESF bus per
1BOA ELEC-3, LOSS OF 4KV
ESF BUS.

Question 7

What do we look at to determine if SI is actuated? What do we do if SI not required?

Answer 7

SI permissive light actuated
Any SI first out
Any SI equipment auto actuated
Either 8801a/b open

Look at PZR pressure, steamline pressure, cnmt pressure and determine if required. Otherwise go to BEP ES0.1.
