Commissioning in Russia of the world's most powerful multi-purpose fast neutron research reactor MBIR is scheduled for 2028, follows from the materials presented on Tuesday at the ceremonial meeting at the State Atomic Energy Corporation Rosatom dedicated to the Day of Russian Science.
Key planned events within the MBIR project for 2021-2028 were highlighted in the presentation of Alexander Kurskiy, the head of the project office of advanced technologies of the management company of the scientific division of Rosatom JSC Science and Innovations, who spoke at the meeting. According to the data from the presentation, it is planned to obtain a license to operate the reactor plant in 2027 and to carry out the physical start-up of the reactor by the end of the same year. An energy start-up of MBIR is planned for 2028 with its commissioning in the fourth quarter of the same year. The multipurpose research nuclear reactor on fast neutrons MBIR with a thermal capacity of 150 megawatts is being built at the site of the Rosatom enterprise "Scientific Research Institute of Atomic Reactors" (RIAR, Dimitrovgrad, Ulyanovsk Region).
It is believed that MBIR will provide the nuclear industry with a modern and technologically advanced research infrastructure for half a century ahead. The unique technical characteristics of MBIR will make it possible to solve a wide range of research problems to justify the creation of new competitive and safe nuclear power plants, including fast reactors for closing the nuclear fuel cycle. At the same time, the research time at the new reactor will be reduced by several times in comparison with the currently operating installations. On the basis of MBIR, it is planned to create an international research center, within the framework of which foreign participants will carry out the experiments necessary for themselves. Thus, with the launch of MBIR, Russia will receive significant additional advantages in the global market for research nuclear facilities, which is also important from the point of view of promoting Russia's interests in the world.
In November 2020, Rosatom signed a new general contractor for the construction of the MBIR reactor. The contract was concluded with the company "Institute" Orgenergostroy ", which leads the syndicate of contractors for all main types of work. The consortium also includes insurance, leasing companies, and partner banks. Previously, Uralenergostroy was responsible for the construction of the MBIR reactor. MBIR was designed by the Rosatom enterprise JSC "Order of Lenin Scientific Research and Design Institute of Power Engineering named after Dollezhal" (NIKIET, Moscow).
