Abstract
The fuel-handling equipment for the Dragon reactor experiment has presented some unusual engineering problems because its design was completed in advance of that for any similar equipment on other reactors using helium as coolant.
The adoption of an in-built charge/discharge machine has facilitated access to the core for removal and replacement of numerous fuel element designs during off-load refuelling periods.
The general scheme for fuel changing is outlined and reasons are given for special measures specified initially with the aim of ensuring functional uniformity combined with maximum reliability. The charge/discharge machine is described in some detail as one of the unique features in the fuel cycle system. Component development testing is mentioned and a report is given of operational experience with the equipment over a period of four years.
