Fabrication of research-reactor fuel elements

Conference ·
OSTI ID:5937149
Research reactors of the plate type operate at low temperatures (38/sup 0/C to 85/sup 0/C). This allows the manufacture of fuel plates of aluminum rather than the more difficult fabrication of materials such as zirconium or stainless steel. The most difficult fuel element to manufacture is for the High Flux Isotope Reactor (HFIR). This fuel element is constructed of aluminum and has 540 fuel plates, 369 in the outer annulus and 171 in the inner annulus. This fuel element assembly operates at 100 megawatts and is 43.18 cm in diameter with a fuel section 50.8 cm long. Fabrication procedures are described.
