According to data from the Private Institution "Science and Innovations" (part of Rosatom), more than 800 research reactors have been built worldwide, with 234 reactors currently operational or temporarily shut down. They are utilized for fundamental research, materials testing, radioisotope production, and other objectives. Nikolay Arkhangelsky, an analyst at the Center for Analytical Research and Development (CARD) of the Private Institution "Science and Innovations," noted in his report that all countries and regions possessing research reactors have plans to extend reactor operational lifetimes and construct new facilities to replace decommissioning units. MBIR will occupy an exceptional place among global research reactors and will support materials science research for all Generation IV reactors, primarily fast neutron reactors. A crucial task for research reactors remains the production of radioisotopes, which will be ensured by existing, newly built, and under-development multipurpose reactors executing diverse research programs. "To ensure a robust foundation of research reactors in the second half of the 21st century, new reactors are being built and planned for construction in various countries and regions alongside existing ones," Nikolay Arkhangelsky emphasized.


The unique capabilities of MBIR will accelerate the development of dual-component nuclear power technologies and the closed nuclear fuel cycle (CNFC), as well as the creation of safe, Generation IV nuclear power plants, emphasized Andrey Shadrin, Deputy Director of the Private Institution "Science and Innovations" (part of Rosatom) and Head of Radiochemistry Division. "In Russia, the RT-1 plant has been operational since the late 1970s, with a comprehensive modernization planned by 2029. In 2024, a pilot demonstration center for spent nuclear fuel (SNF) reprocessing was commissioned in Zheleznogorsk, and the task is to bring it to its design capacity by 2029. In 2038, the launch of the reprocessing module of the industrial energy complex in Seversk is scheduled. The transition to CNFC requires new fuel reprocessing options. The technology developed within the 'Proryv' project already allows for the reprocessing of high-burnup SNF with short cooling times. MBIR is intended to be used for radiochemical research: testing accident-tolerant fuel (ATF), gas-graphite reactor fuel, as well as comprehensive studies of structural materials and fuel. The first step toward closing the fuel cycle has already been taken: MOX fuel for the BN-800 reactor is manufactured from plutonium separated from VVER spent nuclear fuel. In 2027, it is planned to begin reprocessing BN-800 spent MOX fuel, and in 2029, to manufacture refabricated MOX fuel, fully closing the fuel cycle," noted Andrey Shadrin.
