On August 12, 2026, Moscow hosted a meeting of the Management Committee of the "International Research Center based on the MBIR Reactor" Consortium (IRC MBIR Consortium). The meeting was attended by the members of the Management Committee: JSC "SSC RIAR", the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan, Shanghai ZDAN International Co. Ltd., and Consortium Leader of MBIR Reactor International Research Centre, LLC (IRC MBIR, LLC).
The Management Committee meeting was constituent in nature. Along with resolving the agenda items, it initiated the work of the new collegial body and launched the alignment of the interaction mechanism between the Parties. The operational framework established at this stage will serve as the foundation for sustainable cooperation among all collegial bodies of the Consortium – the IRC Council, the Management Committee, and the Advisory Board – during the operation phase of the MBIR reactor.
All agenda items were resolved unanimously, reflecting the Parties' aligned approach to organizing the Consortium's activities and further expanding cooperation within the framework of joint research programs based on the MBIR reactor. These programs include the testing of advanced structural and fuel materials to support Generation IV reactor technologies, closed nuclear fuel cycle (NFC), and addressing challenges in the field of controlled thermonuclear fusion.
Maksim Dranov, Deputy Director General for Financial and Operational Activities at IRC MBIR, LLC, was elected Chairman of the Management Committee. Fahrulla Kungurov, Deputy Director for Innovation and International Relations at the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan, was elected Deputy Chairman.
The outcomes of the meeting will form the basis for preparing the upcoming meeting of the IRC Council, the supreme governing body of the Consortium.

For reference: MBIR is a multipurpose fast-neutron research reactor with sodium coolant and the thermal capacity of approximately 150 MW. The reactor is under construction in Dimitrovgrad at the site of the State Scientific Center - Research Institute for Atomic Reactors (RIAR JSC, a part of the R&D division of Rosatom State Corporation) within the framework of the national technological leadership project "New Nuclear and Energy Technologies". Currently, work is underway on installing the equipment of the reactor's primary circuit: in 2025, the cold filter-traps of the emergency heat removal system loop were installed in their design positions. As part of the primary circuit installation, adapters of hot pipelines have been welded to the reactor vessel and the first pipeline blocks; the installation of the main process equipment in the sodium storage building has been completed; a fuel handling mechanism and steam-water washing sockets for spent fuel assemblies (FA) have also been delivered. In 2026, two emergency heat exchangers weighing 7.3 tons, 5 meters high, and 1.5 meters in diameter have been installed in their design positions.

MBIR is intended for performance of reactor tests, production of radioisotopes, production of modified materials, as well as testing of new type equipment and systems. The unique capabilities of the new reactor are expected to accelerate development of solutions for the two-component nuclear power and the closed nuclear fuel cycle, as well as design of safe Generation IV nuclear power systems. 

The International Research Center (IRC) in the form of an international consortium is established on the basis of MBIR reactor. The Consortium participants gain ‘fast track’ access to carry out the experiments needed for national programs of nuclear energy peaceful applications. The Consortium format allows for flexible use of the reactor resource for the demands of the scientific community. IRC MBIR Consortium is open to new members. The Joint Institute for Nuclear Research, the Nuclear Physics Institute at the Academy of Science of the Republic of Uzbekistan and Shanghai ZDAN International, a Chinese company, have already joint the Consortium as the main participants.

On 16 July 2025, the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan (INP AS RUz) became an official participant in Rosatom’s international research program based on the Generation IV reactor MBIR.
The conference focused on discussing current issues in fundamental and applied nuclear physics, nuclear power, development and application of nuclear technologies; it also aimed to expand international scientific cooperation.
Vasily Konstantinov, Director for International Scientific and Technical Projects at Rosatom State Corporation and General Director of Consortium Leader MBIR Reactor International Research Centre LLC, delivered a report on the capabilities of the multipurpose fast neutron reactor MBIR for testing innovative materials of Generation IV systems. The report outlined the progress of the MBIR project and its future applications.
On 14 October, within the conference framework, a ceremony was held to unveil a monument to Bekhzod Sadykovich Yuldashev, marking his 80th birthday.
B. S. Yuldashev, Doctor of Physical and Mathematical Sciences, Professor, and Academician of the Academy of Sciences of the Republic of Uzbekistan, was an outstanding scientist and nuclear physicist who made a tremendous contribution to advancing research in high energy physics, training young specialists, fostering international cooperation. Those attending the monument unveiling included leaders from the Academy of Sciences of the Republic of Uzbekistan, the Agency for Atomic Energy under the Cabinet of Ministers of the Republic of Uzbekistan, the Tashkent branch of the National Research Nuclear University MEPhI, as well as leading scientists from the republic and abroad. Participants honoured the memory of their distinguished colleague.
For reference:
MBIR is a multi-purpose fast neutron research reactor with sodium coolant and a thermal capacity of approximately 150 MW. The reactor is being built in the city of Dimitrovgrad at the site of JSC "SSC RIAR" (part of the scientific division of Rosatom State Corporation). In December 2024, the installation of technological equipment for the primary heat removal circuit and transport-technological systems of the research reactor began. The reactor is scheduled to be commissioned in 2028. It is expected that the unique capabilities of the new reactor will expand the study of technologies for two-component nuclear energy and closed fuel cycles, and will also help accelerate and justify the creation of safe fourth-generation nuclear power plants.
An International Research Center (IRC) MBIR is being formed based on the MBIR reactor. The scientific group will include Russian and foreign scientists and researchers. The center's activities will be carried out by the consortium "International Research Center based on the MBIR Reactor." The accession of new participants to the MBIR project occurs through the signing of a consortium agreement. This document legally formalizes the relations between the parties and fixes the rights and obligations of participants to use the MBIR reactor resource after its commissioning. Russian and foreign partners gain the opportunity to conduct experiments necessary for national programs for the peaceful development of atomic energy, without the need for direct ownership of the reactor facility and corresponding obligations to ensure its safe operation, as well as control and accounting of nuclear materials. This approach allows for flexible use of the reactor resource, meeting the needs of the scientific community participants.

The conference was organized by the Institute of Nuclear Physics of the Academy of Sciences of the Republic of Uzbekistan as the largest research Centre in the republic and region that is equipped with a research nuclear reactor, a   cyclotron, an electron accelerator, a gamma facility, and a neutron generator.

The roundtable brought together representatives from countries with the most advanced nuclear power industries, as well as reactor technology developers and suppliers.
