What must you have in order to close the first MG set out put breaker?
Both MG set out put breakers must be racked in and open.
With a phase “B” and no other casualties what affect on NESW system?
No affect on NESW pumps already running phase “A”
What two things does the reactor protection system protect against?
Over pressure and departure from nucleate boiling.
What happens to CCW on a phase B.
RCP loads isolate
Delayed neutrons have less kinetic energy than?
