TOMSK, Jun 11 - RIA Tomsk. Researchers of Tomsk State University (TSU) Institute of Smart Materials and Technologies developed a new multilayer material designed for the production of fuel elements of nuclear reactors on fast neutrons; Rosatom enterprises will become consumers of the material, the press service of TSU reported on Tuesday.
Earlier it was reported that since 2011 Rosatom has been implementing the project Proryv (Breakthrough) on the creation of closed fuel cycle technology at the Siberian Chemical Combine. The BREST-OD-300 reactor facility (fast neutron reactor) with the on-site nuclear fuel cycle, as well as the production of uranium-plutonium (nitride) fuel will appear in Seversk. The launch of the reactor is scheduled for 2026.
“Scientific of the Strategic academic units "Institute of Smart Materials and Technologies" of TSU within the framework of the federal target program developed a new multilayer material intended for the production of fuel elements of nuclear reactors on fast neutron ... The main potential consumers of the developed materials and end products – the enterprise of the Rosatom state corporation", – is said in the statement.
It is specified that the three-layer material developed by TSU scientists consists of chrome-containing steel and vanadium alloy and is corrosion and radiation resistant. Its use in products of the active zone of nuclear reactors (in particular, in the production of fuel elements) will ensure the radiation and corrosion resistance of structures at temperatures up to 700 degrees.

"Fast neutron reactors are more efficient and safer than thermal neutron reactors. At the same time, radiation loads on structures in them are much higher. <...> We have developed a new composite with special functional characteristics - increased heat resistance, high resistance to static, dynamic and radiation loads", - the press service quotes the director of the Institute of Smart Materials and Technologies Irina Kurzina.
The new material can be used in the production of components and accessories for nuclear energy and fuel cycle enterprises producing or processing nuclear fuel (production of fuel elements. - Ed.). The project was supported by the Ministry of Education and Science and was carried out with its financial support, the university underlined in the message.
