OSTI ID:4821379

The heat is transmitted from the fissile material to the fuel element casing exclusively by thermal radiation. Suitably, the fissile material is used in the form of cermets or carbides, alone or mixed with graphite, these forms having a high thermal resistance. These materials are shaped into elements, each of which is supported on its two extremities by suitable graphite blocks holding it at a given distance from the inner wall of a stainless steel tube enclosing the elements. This steel tube is positioned inside a reactor cooling channel, the outside of said steel tube being in contact with the coolant circulating in this channel. Suitably, several fuel units of the kind described are placed inside each steel tube alternately with spacer plugs, fixed inside the tube by crimping it on these plugs, which are preferably perforated for heat equalization.
