A CONTROLLED COPY 3/4. 9 REFUELING OPERATIONS 3/4.9.1 REACTOR MOOE.SWITCH LIMITING CONDITION FOR OPERATION 3.9. 1 The reactor mode switch shall be OPERABLE and locked in the Shutdown or Refuel position.
When the reactor mode switch is locked in the Refuel position:
a.
A control rod shall not be withdrawn unless the Refuel position one-rod-out interlock is OPERABLE.
b.
CORE ALTERATIONS shall not be performed using equipment associated with a Refuel position interlock unless at least the following associated Refuel position interlocks are OPERABLE for such equipment.
