COMPOSITE FUEL MODEL MATERIAL WITH INERT POROUS METAL MATRIX AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2014 - IPC G21C3/64 G21C3/60 G21C3/02 

FIELD: physics, atomic power.

SUBSTANCE: invention relates to composite fuel model material consisting of a radiation-inert matrix and particles of a material which simulates nuclear fissile material (minor actinides). The material is characterised by that the inert matrix is made of porous metallic material and particles of the material which simulates nuclear fissile material uniformly coat the inner surface of the pores of the inert porous metal matrix and are in thermal contact with said matrix. The disclosed material is characterised by use of a metal matrix material with stronger contact of oxide particles with the porous metal matrix; the possibility of obtaining a given porosity of the porous metal matrix and degree of filling thereof with a fuel oxide (model oxide); the possibility of obtaining more accurate size tolerance when producing the porous metal matrix; high technological effectiveness of a separate process of producing a porous metal matrix, which enables to vary nuclear and physical characteristics by using different metals and alloys.

EFFECT: invention relates to a method of producing material.
