Remote bolting tools for the JET divertor exchange

摘要

With over 2500 bolting operations to perform remotely, the selection of appropriate tooling was fundamental to the efficiency of the recent JET Divertor Exchange [1]. During mock-up trials using the Mascot force reflecting manipulator it became apparent that many traditional manual techniques were inappropriate. Hence, it was necessary to design special bolting tools to satisfy the remote handling needs. This paper discusses the evolution of this tooling.
