Fast nuclear reactors will be “radiation neutral” – president of the SAR – Science & Space


KAPSEL HARBOR / Crimea /, June 11. / TASS /. The use of next-generation fast neutron reactors in the nuclear power industry will allow Russia to minimize the amount of harmful waste, Russian Academy of Sciences President Alexander Sergeyev said on the sidelines of a forum on youth culture and the arts. Tavrida Friday.

Earlier this month, the city of Seversk in the Tomsk region saw the start of construction of a unique fast reactor, BREST-OD-300 (experimental and demonstrative). It is a Russian-designed fast neutron reactor using lead as a heat transfer agent, equipped with a dual-circuit steam supply system and having supercritical steam parameters.

“New reactors and closed-loop nuclear fuel use concepts will reduce the amount of radioactive waste to virtually nothing. Basically, the spent fuel will have a radiation level no higher than the natural background there, where the uranium was mined, “Sergeyev said.

He pointed out that scientists consider nuclear energy to be environmentally clean, but some phobias in society are still being felt. In reality, the nuclear industry does not produce greenhouse gases and its radiation level is much lower than the natural background noise. The high reliability of the new generation fast neutron reactors is a strong argument against the third fear on the risk of nuclear accident, and the prejudices against the dumping of nuclear waste.

“It is very good that in this respect [nuclear power industry development] Russia is the leader. According to current plans, this facility (the reactor that began to be built in Seversk – TASS) is to come into operation by 2030, “Sergeyev said.

Fast neutron reactor project

The unique BREST-300 reactor began to be built under a project guideline called Breakthrough to create a new technology platform for the nuclear power industry with a closed nuclear fuel cycle and to solve the problem of spent nuclear fuel. The project is implemented in the premises of the Siberian chemical compound of the company Rosatom. The project is expected to produce a competitive product capable of securing Russia’s leadership in the nuclear energy industry.

Rosatom CEO Alexei Likhachov said earlier that Rosatom hopes to start exporting fast reactors and fuel processing modules in 2030-2040. In addition, Rosatom organizations and three Russian universities will create a research consortium to design training programs to train specialists from European countries and China to operate next-generation reactors or fast neutron reactors.
