Proposed License Amendment Containment Equipment Door and Containment Airlock Doors Open Duringi Core Alterations

requires that the containment equipment door be closed during core alterations or movement of irradiated fuel within containment. TS 3.9.4.b. requires a minimum of one door in each airlock to be closed during core alterations or movement of irradiated fuel within containment. The proposed change to TS 3.9.4.a. would allow the containment equipment door to be open during core alterations and movement of irradiated fuel in containment provided: a) the equipment door is capable of being closed with four bolts within 30 minutes, b) the plant is in MODE 6 with at least 23 feet of water above the reactor pressure vessel flange, and c) a designated crew is available at the equipment door to close the door. The capability to close the containment equipment door includes the requirements that the door is capable of being closed and that any cables or hoses across the equipment door have quick-disconnects to ensure the door is capable of being closed in a timely manner. The proposed change to TS 3.9.4.b. would allow both doors of each containment airlock to be open during core alterations and movement of irradiated fuel in containment provided: a) at least one door of each open containment airlock is capable of being closed, b) the plant is in MODE 6 with at least 23 feet of water above the reactor pressure vessel flange, and c) a designated individual is available outside each open containment airlock to close the door. The capability to close the containment airlock door includes the requirement that the door is capable of being closed and that any cables or hoses across the airlock door have quick-disconnects to ensure the door is capable of being closed in a timely manner
