摘要

The present article examines the development and justification of an innovative reactor technology based on the BEST-OD300 fast lead-cooled reactor with inherent safety and mixed uranium-plutonium nitride fuel for operation in a closed nuclear fuel cycle. The article provides the results of additional calculation and experimental studies performed for the reactor coolant pump set, steam generator, and steam generator leak containment system, as well as of neutronic performance studies on the BFS critical test bench and in the IGR reactor, long-term endurance tests of a full-scale fuel assembly model, in-pile tests of fuel rods, as well as systems of automatic instrumentation and control and cladding failure detection. A commercial BR-1200 reactor is demonstrated to successfully combine the BREST-OD-300 engineering solutions with some advances.
