Abstract

The paper presents a concept of specialized sodium cooled fast reactor core designed for minor actinide burning. A special feature of the core at issue is utilization of free from fertile uranium-238 fuel material based on inert matrix with zirconium. The selection of this material enables to rise the portion of minor actinides in a mixture with uranium-235 or plutonium within the framework of the restrictions Sodium Void Reactivity Effect (SVE) and this ensures their efficient burn-up. The paper contains the results of physical calculations of two cores of this type: for modular type reactor of 170 MWe and for BN-800-type reactor.
