Abstract
The use of U3Si2 as a Low Enriched Uranium (LEU) dispersed fuel in Low-Power Research Reactors is investigated in this paper. The fuel proves to be usable if some of the original fuel rods (HEU UAl4–Al fuel) are still simultaneously employed (mixed core) without changing the structure of the actual core. About 3.5712mk Initial Excess Reactivity (IER) is procured. Although the worths of both the control rod and the reactivity devices decrease, the safety of these reactors is higher in the case of the new LEU fuel. If the dimensions of the meat and/or the clad are allowed to change these reactors can be run with a meat 2.15mm outer radius, and a clad 0.58mm thickness. The IER will then be 4.1537mk, and both the control rod (CR) worth and the safety margins decrease.
