Description
Several new types of a dispersion fuel composition based on high-density U-Mo alloys were chosen according to the analysis of literature data and pre-reactor material science investigations. High-density fuel (Hd) is designed for the use in the fuel elements of research reactors in order to reduce enrichment. The in-pile tests of Hd will be conducted in the MIR research reactor (FSUE 'SSC RF RIAR', Dimitrovgrad). In the course of tests the operating conditions of fuel elements of pool-type research reactors will be simulated. The program of in-pile tests and the design of an irradiating device (ID) were developed. The neutron-physical, thermal-hydraulic calculations were made. They validated the possibility of testing the developed ID design ensuring the required test conditions of the HDF samples with proper monitoring of test parameters. (author)
