Applying remote handling attributes to the ITER neutral beam cell monorail crane

Abstract

The maintenance requirements for the equipment in the ITER Neutral Beam Cell requires components to be lifted and transported within the cell by remote means. To meet this requirement, the provision of an overhead crane with remote handling capabilities has been initiated. The layout of the cell has driven the design to consist of a monorail crane that travels on a branched monorail track attached to the cell ceiling. This paper describes the principle design constraints and how the remote handling attributes were applied to the concept design of the monorail crane, concentrating on areas where novel design solutions have been required and on the remote recovery requirements and solutions.

“…The solution developed for this involves a series of tools and equipment to be deployed from within the heating neutral beam line vessels, via a series of self installed rails to unfasten it, transport it into casks, while containing contamination. The design of the overhead monorail crane is ostensibly described in O Crofts [2] and therefore is not repeated here.…”
