ABSTRACT OF THE DISCLOSURE The improved fuel channels for Candu type nuclear reactors are provided with pressure tubes sealed to the end fittings by rolled joints recessed into the end fittings, having fuel located in the channel by means of flow-through shield plugs locked in position by fuel latches. The coolant feeder con- nections are located just outboard of the end shields of the calandria vessel, with a channel closure just outboard of each connection point. The end fittings may extend past the feeder bank to allow the fuelling machine to latch on, for refuelling the channel. An alternative arrangement provides for termination of the fuel channel extensions adjacent the channel closure, with the fuelling machine having a correspondingly extended connector to reach through the feeder bank to the end fittings.
