BN-800 fast neutron reactor starts working on “fuel of the future”

The Russian nuclear power industry was the first in the world to use MOX fuel for the operation of reactors, which was called “fuel of the future” only yesterday.

The press service of Rosenergoatom Concern announced the loading of the first serial batch of nuclear fuel into the reactor:

The first serial batch of MOX fuel was loaded into the BN-800 reactor of power unit No. 4 of the Beloyarsk NPP. Following the first overhaul in its history, the unit successfully resumed operation.

The commercial operation of the 4th power unit of the Beloyarsk NPP, operating on fast neutrons, began in 2016 and became one of the final stages of implementation Technology "Closure" of the fuel cycle.

Actually, with the loading of industrial MOX fuel, which uses depleted uranium and plutonium extracted in the process of reprocessing spent nuclear fuel from thermal neutron reactors, the cycle can be considered closed.

Nuclear scientists believe that the use of "fuel of the future" will significantly reduce the amount of radioactive waste due to the "burning" of hazardous radionuclides in spent fuel from conventional nuclear power plants.

According to experts, Russia, which was the first to solve the problem of creating an efficient MOX fuel, will squeeze out competitors in the world market of manufacturers of fuel for nuclear power plants.

    And I always say: "Don't try to catch up with someone. We must create our own - fantastic, and let them catch up with us !!!!!"

    ... with the loading of industrial MOX fuel, which uses depleted uranium and plutonium released during the processing of spent nuclear fuel from thermal neutron reactors, the cycle can be considered closed.

    - Some superficial arguments ... - And how long will this loaded "batch of fuel" be used and how constantly it will have to be reloaded with a new batch ... - every 3, 6, 8 months ??? - And what to do with the formation of "extra isotopes" of plutonium itself ???
    - Yes, and plutonium itself is so radioactive (200 times more active than uranium) and so toxic .. that you need to think 000 times before starting something with plutonium ...

      - It can be seen ... how the whole site fraternity rejoices with its prepared advantages ...
      - If only they would not make people laugh ... - And so all this illiterate brotherhood so unanimously approves ???
      - This is what happens ... - that before the appearance of the MOX, the construction workers simply shoveled radioactive material directly into the reactor ...
      - And then suddenly MOX fuel appeared and ... and ... and ... and ... and now all the same construction battalions can simply stab it with crowbars and sledgehammers (like ceramics) and push it into the reactor in pieces ... - Progress just there !!! - Let's all together continue to applaud ignorance ... - Well, -Hahah, and only ... - It's a pity even for a minus to evaluate such illiterate "reasoning" ...

    This is a major breakthrough for our scientists. If someone does not understand: MOX fuel is not a metal, in fact, it is a ceramic. In the event of a serious accident, the fuel will not drain into a molten, terribly radioactive puddle, as in Fukushima, and will not create an "eternal" uncontrollable nuclear reactor. You can take your time, in a calm atmosphere to deal with the accident. No risk to human health and lives.
    This technology allows the use of waste from other nuclear weapons, increases the efficiency of using extracted natural uranium by 100 times, and the amount of radioactive waste decreases by several times.
    The Americans tried to create this technology, spent many times more money and could not do anything.

      - No, well, it’s necessary ...- an entire department of construction battalion came running .. with the shovels at the ready ...- And with the same shovels they grabbed the pluses apparently and invisibly ...
      - Hurray ...- the construction workers are already in charge in the Russian nuclear power industry ...- As, however, in Roskosmos ..., as in the Russian Defense Industry, as in all other Russian key areas, areas ... What a breakthrough ... -To cry, or laugh ...

        Irina, apparently, in your youth the construction battalions "upset" you very much. True, in Russia, this type of troops ordered to live for a long time in the last century. Correctly, wink at least in old age, recoup. laughing

          - Yes, personally, I am so old that even musketeers could upset me ... what kind of construction battalion are there ...
          - As for the construction battalion specifically, then ... then ... then ... then personally I found out about them from my service relatives ... - I specifically asked them about this "branch of troops" ... - None of my served in the construction battalion ... - Mor. Fleet; Marine Corps (personally, I have already written about this once); Border Troops; Airborne Forces and even the Presidential Regiment, etc ... - in these types of troops at different times, different generations of my relatives served both in the USSR army and in the Russian army (there are also veterans of military operations in Afghanistan and Chechnya) ...
          - I must say ... - Mother Siberia has always and at all times strained precisely for the "shock military unit" ... "shock combat arms" ... - Personally, I myself am liable for military service (I also wrote about this) .. ...
          - I personally learned from my service relatives (I was specially interested) that the construction battalion ... is, how to put it more decently ... - these were the most dumb, recruited from social strata of the population with low social responsibility (criminal record, lack of average education, health restrictions, etc.) "troops" ... - and this, if you take the Slavic European population of Russia ... - And so ... - the non-Russian population of the USSR and Russia was mainly called to the construction battalion ... -population from the outskirts, nat. republics, etc ... -And the tasks of this "branch of troops" were very, very "conditionally limited" ...
          - They weren’t given weapons at all ...- Interestingly ...- how did the builders at all take the oath ??? -With a shovel at the ready, or what ???
          - And you, Mr. duche (Salih), have already put me a minus ... - probably, and you are guided by "the courage of a veteran of the construction battalion" ...
          - Personally, I will not put a minus to you ...

            "That ... then ... then ... then ... then" - it is very difficult to understand why, or why this particular manner of writing, laughing and yet - you are not yet accustomed to the fact that almost everything is possible in our country - a drunken ensign at the military registration and enlistment office did a lot by sending the boy to the construction battalion for a long time, but the warrantor did not know that the boy managed to live a lot with his parents, therefore, when the grandfathers gathered to educate him, the boy simply ran almost along the vertical wall and upset the "grandpa", it doesn't matter ... but after such an incitement they disappeared somewhere, especially when several uncles of an oriental look arrived at the unit, who many times, well let's call it conditionally, bowing - the rest - details. hi
            So anyone could get into the construction battalion ...

            Irina, I’m on the drum, what kind of mathematical sign will you put under my answer, you just express your thoughts in such a way that a strong belief is created that you live on the other side of the ocean, and the achievements of our scientists and builders cause you attacks of rage. A man who has a military dynasty will never write like that, anathema to those who, for the sake of your peaceful coexistence, have given their whole lives to defend the Fatherland. The first experimental reactor was assembled from graphite blocks and fissile material MANUAL our scientists. Do not waste your skepticism and do not spray the poison of slander in public networks. It does not color you. hi

              - And it started, and it went ... - And it was necessary to start with this ... - this is a "win-win trick" ... -All will support in this at once ...
              - Well, I wish you success ... in this field ... the last "true patriot" of Russia ...

    - It is difficult to understand the reasoning (and whether it is worth doing) "construction battalions" about "Russian nuclear power" ...
    - Well, it is clear .. that - "From prison and from the scrip - do not renounce" ... - and also do not "renounce" and from the construction battalion ... - Though in this the site audience showed understanding ... - Yes, no one and did not deny ... - Who denied it at all ??? - Anything can happen ...
    - But to continue to say "white" that it is "red" ... or vice versa - this is already ... from the category ...
    - And the position of the "site construction battalions" is good ... - you can just be silent (and creatively sniff) and put pluses and minuses ... - It is not necessary to broadcast and explain something at all ...
    - Here, judging by the abundance of "pluses" and "minuses" exposed with such agility and without any argumentation .., then one can easily understand the level of development of these "put down" individuals themselves ... -There is no need to blame the "drunken ensign "- if you don't have your own brains ...
    - And when there are no brains, then the time has come to talk about "Russian nuclear energy" ... - Let it be at least nonsense of a "drunken ensign" ... - it doesn't matter at all ... - It will always be supported by a whole crowd of adherents of this " drunken ensign "... - And judging by the abundance of" pluses "and" minuses "- this is what happens ...
    - It remains only to be horrified by this abundance of pros and cons; at the same time horrified by the fact that in the real industrial and economic life of Russia there may also be such adherents of the "drunken ensign" ... which is already much more terrible and terrible ...
    - Most likely, this is how it is ... in the Russian economy and in particular - in the "Russian Atomic Energy" ... these "pluses" and "minuses" can cause so much harm and irreparable trouble ... that even if all these "plus" and "minus signs" triumph only here ... here ... here ... here on the site ... and do not go beyond ... - It's better this way .. than ....... .........
    - Not everywhere you can so successfully translate the arrows to the "drunken ensign" ...
