MBIR reactor

will become one of the key elements in the renewal of the nuclear industry's experimental capabilities and the highest-precision research facility

MBIR - is the largest research reactor in operation and under construction on the planet and will provide the nuclear industry with a modern and technologically advanced research infrastructure for the next 50 years.

MBIR unique experimental and technological possibilities will allow to essentially expand directions of studies regarding grounds of concepts in two-component nuclear energetics and closure of fuel cycle, as well as significantly accelerate the creation of safe nuclear Generation IV power plants.

The exceptional physical characteristics of the MBIR reactor will be best suited for materials science experiments, development of new technologies for production of radioisotopes and modified materials, testing of fuel, new coolants and much more.

NON-POWER APPLICATION

Meetings of the IRC MBIR Advisory Council specialized committee are held on a regular basis to develop the scientific research program of experimental research based on the MBIR reactor and broadly discuss the reactor's possibilities in non-power applications of nuclear technologies.

Thus, May 26, 2023, Tashkent, Institute of Nuclear Physics (INP, under the Academy of Sciences of Uzbekistan) hosted a meeting of the Committee on Non-Power Applications of Nuclear Technologies under the Advisory Board of the International Research Center Based on the MBIR Reactor (IRC MBIR).

The event was attended, both face-to-face and online, by over 40 representatives of the largest Russian and overseas nuclear companies, major scientific and educational institutions of Uzbekistan, Kazakhstan, China, Armenia, Algeria, Brazil and South Africa, in addition to international organizations, such as IAEA and JINR. The unique experimental equipment of the MBIR reactor will ensure the solution of the most important tasks in the non-power application of nuclear technologies.

Minimize

A wide range of biomedical research, including boron-neutron-capture, neutron and combined therapy, will be possible involving radiation exposure, which will ensure future improvement of nuclear medicine tools and organization of practical use of neutron beams for medical purposes.

The robust research base of the MBIR reactor will provide ample opportunities to develop the technology for producing radioisotopes of strontium, nickel, cobalt, gadolinium, and sources based on them, as well as to organize the generation of radionuclides with low neutron capture cross sections.

The most important fundamental and applied research will be carried out and based on the MBIR reactor, including the use of ultracold neutrons. The unique data obtained during the experiments at MBIR will help substantiate research in the area of astrophysics.

Applied experimental work involving radiation exposure will ensure the creation of technologies and organization of production for neutron doping of silicon, which is widely used in electronics.

The MBIR's technical features will make it possible to conduct experimental studies of reactor-irradiated materials and products in support of neutron radiography and tomography techniques for reactor-irradiated materials.

MBIR neutron-activation analysis will enable a mass multi-element analysis of biological, environmental, and geological samples: nuclear studies of cultural heritage objects, determination of toxic elements content in the environment, studies of new medical preparations and sorbents, food quality, and safety testing.
