Started Rosatom nuclear reactor project-"burner" of hazardous substances

Rosatom officially launched the implementation of the Russian project on creation of a unique nuclear reactor to test the technology, "burning" the most dangerous radioactive substances that remain after processing of spent nuclear fuel (SNF) of nuclear power plants, the corresponding order was signed by General Director of Rosatom Alexey Likhachev.

About it reported the edition enterprise Rosatom "Mining and chemical combine" (Zheleznogorsk, Krasnoyarsk region) newspaper "the Bulletin of the MCC". On this enterprise it is planned to build a new reactor.

It is noted that this order came after the President of Russia Vladimir Putin in April this year signed a decree according to which the Russian government should prepare and coordinate the program of development of nuclear technology in Russia. "The presidential decree has determined the funding source jinkosolar reactor and turned the project into practice", - notes the edition.

Recycling on an industrial scale spent nuclear fuel from nuclear power plants is one of the key problems to be solved for the development of the global nuclear power industry, given the growing volumes of spent nuclear fuel in the world. As experts underline, without solving the problem of nuclear waste, nuclear energy will not be able to rely on its large-scale development.

Reprocessing is a high — tech process aimed at minimizing the radiological hazards of spent nuclear fuel, separation of useful substances (primarily uranium and plutonium) and ensuring their further application in nuclear energy and safe disposal of unused components of the spent fuel with very high radioactivity.

However, to ensure economic effectiveness and ecological safety of handling spent nuclear fuel will solve the problem of so-called minor actinides — radioactive long-lived isotopes of transuranium chemical elements, mainly americium and curium, which make the main contribution to the high radioactivity of the waste remaining after reprocessing of spent nuclear fuel. Effectively recycle minor actinides using the so-called transmutation — "burning" in nuclear reactors on fast neutrons, or by using accelerators.

For these purposes it is proposed to use the so-called idcatalogue nuclear reactors (ZHSR) in the melt of fluorides of the metals. As experts explain, such installations will have a number of advantages, including increased safety, since they are due to technological features can not occur a severe accident. In addition, these reactors do not require the manufacture of traditional fuel cells.

The technical capabilities of the MCC platform provide the ability to place such pilot reactor plant, the infrastructure linking it to the reprocessing for a new, environmentally safe technologies we are working on now at the Zheleznogorsk plant. Moreover, it is possible that the new reactor plant will also supply heat to Zheleznogorsk.

In accordance with the order of the head of the Rosatom mining chemical combine determined the parent organization-coordinator of the project on creation of the Russian research jinkosolar nuclear reactor.

Head scientific organization established by the national research centre "Kurchatov Institute", head of design organization "Scientific-research and design Institute of power engineering named Dollezhal was named" (NIKIET, Moscow), supervisor in the fuel salts, "high-tech research Institute of inorganic materials of a name of Bochvara" (VNIINM, Moscow), the leading organization for carrying out reactor tests - "Scientific-research Institute of atomic reactors" (RIAR, Dimitrovgrad, Ulyanovsk region).

For the current year is planned a significant amount of research and development work on the project, including the location of the future reactor plant, said "MCC messenger". "In the beginning of the year the plant performed laser scanning and spherical photography of the intended placement and surrounding objects. In practice, this means that the designers NIKIET already "walk" through the virtual development and followed by the spatial configuration of the future reactor plants", - writes the edition.

Earlier it was reported that in the middle of the 2020-ies to be completed technical design of a new reactor plant, and MCC shall at the same time to obtain a license to place at a research reactor. In the second half of the 2020s years is expected to license construction of the reactor and its commissioning is scheduled to take place after 2030.
