The decommissioning plan encompassed a combination of remote, semi-remote and manual operations. The principle stages foreseen to undertake the remote work included:- a remotely operated remote dismantling machine (RDM) to deploy tools to dismantle the high dose components, a waste route through which to move the components, sort them, assay and grout, an interim storage facility for the grouted containers (boxes). The RDM consisted of two handling systems deployed beneath a turntable mounted at the reactor operating floor level. The first system was an extendable mast from which a remotely controlled manipulator was suspended. The second system consisted of a series of suspended crane rails that enabled a 3 tonne hoist to travel across the reactor vault into the adjacent cells. A two storey building mounted above the turntable provided access for tool changing and maintenance.
