CONTROLLED COPY REFUELING OPERATIONS 3/4.9.6 REFUELING PLATFORH LIMITING CONOITION FOR OPERATION 3.9.6 The refueling platform shall be OPERABLE and used for handling fuel assemblies or control rods within the reactor pressure vessel.

APPLICABILITY: Ouring handling of fuel assemblies or control rods within the reactor pressure vessel.

ACTION:

With the requirements for refueling platform OPERABILITY not satisfied, suspend use of any inoperable refueling platform equipment from opet:ations involving the handling of control rods and fuel assemblies within the reactor pressure vessel after placing the load in a safe condition.

SURYEILLANCE REQUIREMENTS 4.9.6 Each refueling platform crane or hoist used for handling of control rods or fuel assemblies within the reactor pressure vessel shall be demonstrated OPERABLE within 7 days prior to the start of such operations with that crane or hoist by:
