APPLICABILITY:

MODE 5, with Reactor Coolant loops filled.

ACTION:

a.

With less than the above required shutdown trains / loops OPERABLE or with less than the required steam generator level, immediately initiate corrective action to return the required trains / loops to OPERABLE status or restore the required level as soon as possible.

t b.

With no loop / train in operation, suspend all operations involving a reduction in boron concentration of the Reactor Coolant System and immediately initiate corrective action to return the required loop /

train to operation.

  • All reactor coolant pumps and shutdown cooling pumps may be de-energized for up to I hour provided (1) no operations are permitted that would cause dilution of the Reactor Coolant System boron concentration, and (2) core outlet temperature is maintained at least 10*F below saturation temperature.
