ABSTRACT
Pin-type fuel elements of new generation have been developed for conversion of Russian-built research reactors to LEU. This paper contains the main results of out-of-pile investigations during manufacturing of experimental batches of mini- and full size fuel elements for irradiation tests in “MIR” (Dmitrovgrad) and VVR-M (Gatchina) reactor respectively. U-Mo LEU fuel granules have been manufactured both by centrifugal atomization and by hydride-dehydride process. Loading of mini-fuel elements made 4 and 6 g U/cm3, whereas full size ones were loaded to 5.3 g U/cm3. All fuel elements went through quality control of cladding thickness and uniformity of fuel granules distribution through the length of each one.
