Abstract

Each fuel element is extended upwards from the core into an integral or two section spigot jointed pipe through which the coolant is ejected from below. A float of neutron absorbent material in this pipe takes up a position dependent on the pressure drop produced by the coolant flow. Gated flow control outlets may be provided at the centre of the pipe above the core to set the float height and at the top of the pipe and there may be a gated inlet at the bottom.
