In order to charge and dischnrge a fuel element with its thermocouple attached, the use of a load-bearing, flexible sheath, formed by a stainless steel wire helix, is proposed by the UKAEA (this could be Calder Hall). The thermocouple cable passed through the sheath which is attached, via screwed tapered pins and clamping nuts, at one end to a lifting block and at the other to a coupling boss. The lifting block screws into a section carrying the fuel element itself. The free end of the cable is attached to a terminal block. The boss connects with another coupling in which is clamped another length of hollow, flexible cable sheathed in stainless steel braiding. Into the other end of the cable fits a spigot connecting via a plug and a coupling flange to a stainless steel lifting wire. For charge/discharge operations, the cable is detached from its terminal block, tbe assembly of the lifting wire to the cable made, and the free end of the cable fed through. The union nut is then tightened to take the weight of the element.
