Specialists of the Tomsk Polytechnic University (TPU) improve an efficient and cheap method of compacting solid radioactive waste during the reprocessing of spent nuclear fuel (SNF) used at nuclear power plants.

Tomsk scientists have mastered the method of processing nuclear fuel in solid form


Dmitry Demyanyuk, Deputy Director of the Physics and Technology Institute at TPU, noted that solid waste storage is much safer, since radionuclides cannot be released into the environment. Currently in the world using the technology of dissolving fuel in acid, translating it into a liquid state. Remaining after the chemical processing of solid waste alloyed with quartz sand.

“We develop special technology and offer special blends that are exothermic. When using them, there is no need to maintain a high burning temperature in the system. This mixture is mixed in the required proportions with solid radiation waste and additives, which help to emit more heat required for the reaction, "- says Demyanyuk RIA "News".

The deputy director said that the mixture is placed in a container and ignited. As a result, a ceramic composite with a porous structure appears, which allows gases emitted during the decomposition of a substance to fill the pores without deforming the samples, therefore the geometrical dimensions of the material do not change.

According to the scientist, it will help to extract useful materials in the future. This technology is developed in the framework of the state order. It is planned to use it at the enterprise of the state corporation Rosatom.

    If the method of compacting nuclear waste is harmless, then this is a great achievement in nuclear technology.

      Guys, and after that, do not say or whine that everything is so bad in the space industry:

      The Cygnus space truck, which was supposed to deliver valuable cargo to the ISS, exploded immediately after launch from NASA's cosmodrome on Wallops Island. The explosion occurred approximately six seconds after launch.

      It was reported the day before that the launch of the Antares carrier rocket with the American cargo ship Cygnus was postponed for 24 hours due to the fact that a ship appeared in the restricted area where the spaceport is located, which could not be reached. The ship was supposed to deliver to the International Space Station more than two tons of payloads.

      PS Putin and the FSB agents are to blame. Infa 100%.
      Psaka will confirm.

    In the Far East, before that, a method was developed for processing liquid waste into solid waste, so that now a single technological chain is obtained.

    In my opinion it’s cheaper to send radioactive materials into space, for example, towards the Sun. The main thing is that the missiles are more reliable and do not fall to Earth.

      And if an accident happens ?! No developer will give a 100% guarantee! Missiles have fallen and will fall. Both ours and foreign. Today, here, the American Antares exploded. Now imagine what would happen if a rocket loaded to the eyeballs of highly toxic radioactive waste crashes over the Earth, at an altitude of, for example, 50km, 100km? A catastrophe of a planetary scale may occur. Therefore, I think it’s not worth the risk.

    And we also plan to build a BREST fast neutron reactor, which, as I understand it, can use spent nuclear fuel as fuel.

    so it is - REVOLUTION in the nuclear industry ... request
    ALL radioactive waste will be used in nuclear energy!
    after which NOT RADIOACTIVE decay products will be obtained.
    good
    collected, collected all radioactive Г.from all over the world "quietly" FOR their MONEY ... lol
    Now boom reprocess into new fuel for NEW reactors NPP !
    which they will build (a little later) around the world !!!
    wassat

    drinks
    Glory to SOVIET SCIENCE!

      Well, not quite so, but close to the text. The radioactive waste in the reactor under the influence of a powerful neutron flux begins to divide, as it were, "burn out", to less and less active components. Waste will not reach the "neutral state", but it can actually significantly lose activity.

    Damn, how many nuclear physicists are there, where to run, pancake ... I have never been a physicist, and certainly not a nuclear engineer. But like anyone who has served in the army, I understand a little. our country is the only one in the world that can instantly destroy the United States. Unfortunately, these buggers can do the same to us. Some kind of stalemate turns out. It is impossible to be friends, too different mentality (in what, in what, but I am sure I will fagot, and even openly, and even dressed up in women's clothes, in the army of the Russian Federation they will kill, well, they will do it right) - To fight is no less impossible , too huge nonsense in both countries in store. An eternal stalemate turns out.
