2) Cold Shutdown The reactor is in the cold shutdown condition when the reactor has a shutdown margin of at least 1 percent Ak/k and reactor coolant temper-ature is s200*F.

3) ~ Refueling Shutdown L The reactor is.in the refueling shutdown condition when the reactor is subcritical'by at least 5 percent Ak/k and T,., is $140*F. A refueling shutdown refers to a shutdown to move fuel to and from the reactor Core.

4) Shutdown Margin '

Shutdown margin is the instantaneous amount of reactivity by which the reactor core would be subcritical if all withdrawn control rods were tripped into the core but the highest worth withdrawn RCCA remains fully withdrawn. If the reactor is shut down from a power condition, the hot shutdown temperature should be assumed. In other cases, no change in temperature should be assumed. .

h. -Power Ooeration '

j -The reactor is in power operating condition when the reactor is critical and l

the. average neutron flux of the power range instrumentation indicates '

greater than 2 percent of rated power.

i. Refuelina Ooeration-Refueling operation is any operation involving movement of core components (those that could affect the reactivity of the core) within the containment when the vessel head is removed.

j. Rated Power

. Rated power is here defined as a steady state reactor core output of 1518.5 MWT."

k. Thermal Power Thermal power is defined as the total core heat transferred from the fuel to the coolant.
