Abstract: Annular nuclear fuel rods are disclosed. The annular nuclear fuel rods include an outer cladding tube made of ceramic composite or cermet composite, an inner cladding tube made of ceramic composite or cermet composite, a nuclear fuel region located between the outer cladding tube and inner cladding tube, and an open channel for liquid coolant to flow.

Abstract: A coating for protecting a Zirconium alloy based layer of a nuclear fuel rod cladding is provided. The coating comprises a primary layer. A microstructure of the primary layer is comprised of a number of grains and is randomized. The primary layer is configured with a density of about 94.5% or greater. A cladding for a nuclear fuel rod and a method for producing a cladding for a nuclear fuel rod are also provided.

Abstract: A method is described herein that produces UN from UF6 in at most two steps comprising UF6→intermediate→UN. The principle of the reaction is that in a first step, UF6 would be reduced to UxNy, where x may be an integer selected from 1 and 3, and y is an integer selected from 1 and 2. Reduction occurs at or near the surface of a gaseous membrane electrode where it is also in contact with a nitrogen bearing salt. In a second step, UxNy decomposes to UN and N2 gas, either in the same reactor as the first step or after removal to a separate unit for further processing.
