Rosatom presented a conceptual model of a two-component nuclear energy system in Beijing.

The state corporation «Rosatom» participates in the China International Nuclear Industry Exhibition Nuclear Industry China (NIC2026), which takes place in Beijing from April 22 to 25, 2026. The event has gathered over 100 Chinese and foreign organizations, including the largest global energy corporations, leading research institutes, and state bodies of China.
The centerpiece of Rosatom's exhibit was a multimedia model of a two-component nuclear power system. The project envisages the creation of a new technological platform for the nuclear industry based on a closed nuclear fuel cycle using fast neutron reactors. Achievements of years of Russian-Chinese cooperation in the field of nuclear technologies were also presented. These include the Tianwan and Xudabao nuclear power plant projects and collaborative work on "fast" topics.

The booth of the Russian nuclear industry was visited by leaders from the China Atomic Energy Agency, heads of the largest nuclear corporations in China, and others.

During the event, Boris Arseev, Deputy Director of the Block for Development and International Business – Director for International Business of the state corporation «Rosatom», and Artem Goncharuk, General Director of the Regional Center «Rosatom East Asia» in Beijing, presented key Russian developments in the field of fast reactors and IV generation technologies within the framework of the «Breakthrough» project and the international research reactor on fast neutrons MBIR to the delegations.

IV generation energy systems are a generation of nuclear energy systems (according to the classification adopted by the International Atomic Energy Agency, IAEA), which imply the application of various technologies united by a common result – higher fuel efficiency, increased safety, energy efficiency, reduced spent nuclear fuel, etc. IV generation systems have the potential to radically change nuclear energy, primarily through a new level of safety, an expanded fuel nomenclature, and a significant reduction in radioactive waste. Russia is one of the leaders in the development of IV generation technologies: preliminary design work has begun for the BN-1200M power unit at the fifth unit of the Beloyarsk NPP; in the Tomsk region, at the site of the Siberian Chemical Combine (AO «SHK», a company of Rosatom's Fuel Division), nuclear power plants with a BRSP-OD-300 reactor and an on-site closed nuclear fuel cycle are being created for the first time in global practice.
MBIR is a multipurpose research reactor on fast neutrons with a sodium coolant with a thermal power of 150 MW. The reactor is being constructed in Dimitrovgrad, at the site of the State Scientific Center – Research Institute of Atomic Reactors (AO «GNЦ НИИАР», part of Rosatom's Scientific Division) as part of the national project on technological leadership «New Atomic and Energy Technologies». MBIR is intended for experimental work, production of radioisotopes, production of modified materials, as well as testing of new types of equipment and technological systems. It is expected that the unique capabilities of the new reactor will accelerate the development of two-component nuclear energy technologies and the closure of the nuclear fuel cycle, as well as the creation of safe fourth-generation nuclear power installations.
