Maintenance concepts for an ignition test reactor

OSTI ID:6839697
A remote maintenance concept has been developed for the Ignition Test Reactor (ITR) which provides for maximum contact maintenance in all areas exterior to the shielding so as to minimize the remote maintenance equipment cost and maximize the facility availability. This concept involves the use of a highly effective reactor shield which minimizes the activation of components outside the shield envelope and permits contact maintenance in that region 24 hours after reactor shutdown. The major pieces of remote maintenance equipment required for access to the unshielded areas and for repair or replacement of critical components of the reactor are identified and described. The major pieces of equipment include a bridge-mounted shielded cab, a vehicle shielded cab, access port removal/replacement equipment, access port mounted manipulator, in-vessel rail mounted machine, upper maintenance shield module, and outboard maintenance shield module. Several major remote operations required for reactor maintenance are described to reflect how the remote maintenance equipment is used and illustrate how the reactor is designed to accommodate potential maintenance requirements. The specific maintenance operations are the removal of the upper shield, removal of the outboard shield, and removal of the inboard shield blocks.
