Shillitto, A; Dean, N

A graphite-moderated, gas-cooled reactor was constracted having the fuel elements accessible from the bottom of the moderator instead of from the top as in other reactors. The elements are maintained in operating position by spacers and, when their discharge is desired, a gate valve is opened and tbe elements are lowered by means of guide rods into a discharge machine outside the pressure vessel. The advantages of such a discharging arrangement are that the elements lower themselves by gravity; that, since the gas inlets are in the lower part of the pressure vessel, the discharge is carried out in the coolest region of the reactor; and tbat control rods are not interfered with on the top of the mcderator.
