Rosatom has started construction of the world's first safe nuclear reactor


The construction of a unique BREST-OD-300 power unit has started at the site of the Siberian Chemical Combine (Seversk), owned by the Rosatom state corporation. This is an important event for the global nuclear power industry, since the BREST reactor, which will form its basis, is the first concept in the world that meets the set of safety and security requirements of large-scale nuclear power. the economy.


The power unit with an authorized electric power of 300 MW with a fast neutron reactor will be part of the experimental demonstration power complex (ODEC), which is being created within the framework of the Breakthrough project. The implementation of the latter started back in 2010. The launch of a unique reactor is expected after 2025.

It should be noted that BREST is a reactor with natural safety properties. Its design excludes prompt neutron acceleration. Consequently, it does not require the construction of additional engineering barriers, and its use at nuclear power plants completely excludes the likelihood of accidents like Chernobyl.

Another important nuance is the presence in the future ODEK of a complex for the production of uranium-plutonium nuclear fuel, as well as a complex for the reprocessing of spent fuel. The result will be a closed on-site nuclear fuel cycle, which makes it possible to prepare new fuel for the reactor from the unloaded fuel.

Uranium-235 is used as a fuel in BREST. Its content in natural uranium is less than 1%.

The reactor itself, due to the combination of the properties of dense nitride uranium-plutonium nuclear fuel and lead coolant, will be able to operate in the so-called equilibrium mode. In other words, the amount of produced plutonium will be comparable to the “burnt-out” one. Consequently, it will be possible to produce new batches of "fresh fuel" from it at the above-mentioned complexes, and so on in a circle.

Finally, it should be added that the aforementioned BREST is a prototype of a "fast" BR-1200 reactor also with a lead coolant. According to Rosatom's plans, the latter will form the basis of a commercial power unit with a capacity of about 1200 MW.

      It may very well be, because it is useful, makes a profit and provides electricity. Unlike the aforementioned ones ... There is not much benefit from them, rather the opposite, and these two vacuum cleaners only pull money.

    Mom .... So it turns out what efficiency? It generates energy and makes fuel for itself ...

    - Ha ... - here it is "the moment of truth" !!!
    - Well, where to put all this energy, then ??? - Where to use such a colossal amount of electricity ??? - Or in ... in ... in Western Siberia, the Center of Siberia, and Eastern Siberia, household electrical energy (housing and communal services) will simply become free ??? - And even then ... - how much more will it remain "unclaimed" ... - Here and "household gas" (housing and communal services), which have not been fully provided for the entire population of Siberia will not need ... - and gasified houses will stop constantly exploding ... from a gas leak ... - when everything switches to electricity ...
    - And all these expensive "gas projects" ... - "YAMAL LNG" ... - all these gas pipelines, pipelines and all these communications will remain out of business ... - as unnecessary at all ... - Only export will remain .. . - and even then - for a very short time ...
    - Yes, I have built several "such nuclear power plants" in Russia - in all regions, throughout the country, and full energy supply ...
    - About gas pipelines (as obsolete and unnecessary) personally, I have already written quite a lot ...
    - But who will close these projects ??? - Who will allow ??? - And how will the oligarchs collect "funds" from the people ???
    - Yes, the oligarchs would rather arrange accidents at these nuclear power plants than close their lucrative projects of all kinds ...
    - So it's too early to rejoice ... - Alas ...

      Irina! There is not enough electricity, a shortage, a shortage of it everywhere - you need to charge the gadgets, feed the armies to the sofa ... And you ... What to do with it?
      There is still all kinds of industry: food, metallurgy, smelting aluminum, titanium ... This is a trifle. And to power the light bulbs with tungsten filament?

        At the end of 2019, the total installed capacity of UES power plants
        Russia amounted to 246 342,45 MW.
        Electricity generation by power plants of the UES of Russia in 2019
        amounted to 1 billion kWh. Electricity consumption in 080,6 was
        1 billion kWh.
        The annual maximum power consumption of the UES of Russia was recorded in
        10:00 (Moscow time) 24.01.2019/49,99/XNUMX at an electric current frequency of XNUMX Hz and amounted to
        151 661 MW. At the same time, the load of power plants of the UES of Russia amounted to
        153 508 MW

          - Yes, that's just the point !!! - Personally, I am writing about this !!!
          - Here it is ... - "moment of truth" !!!
          - My plus to you !!!

      Based on your logic, don't you need to do anything?

    I understood. The central bank on it for nothing (the fuel is self-replicating!) Crypto rubles will be mined to the National Welfare Fund. And it will not be necessary to borrow from anyone (including the population through OFZ). And for every wish of the government there is a crypto-ruble. Pension age will be immediately reduced to 50 for men and 45 for women. Let's live! yes From the Rosatom website:

    The IAEA has recently issued an important generalizing document, in which it officially declared: the closure of the NFC based on fast reactors will reduce the radioactive toxicity of radioactive waste by 100-200 times, and reduce the holding time of radioactive waste from more than 100 thousand years to less than 1 thousand years due to afterburning long-lived components of SNF - minor actinides.

    Why are 1000 years important? The answer is in the same place:

    According to the latest calculations, the containers in which the spent nuclear fuel is stored can be in working order for no more than 1 years. Then radionuclides begin to migrate from the container. If the equivalence is not achieved in 1 years, the incidence of cancer in the regions where spent nuclear fuel is located will increase by 15% compared to the spontaneous level.

    A big step in the development of nuclear energy.
    The question is how much electricity will become cheaper and whether it will become cheaper at all. This will ultimately be an indicator of efficiency. Otherwise, it can turn out like oil and gas - it seems like a lot and prices should go down, but in practice everything is exactly the opposite.
    And another question, the fate of the equipment (radioactive) that has exhausted its resource

    The reactor is needed only because it can work on the "working off" of the previous generations. What was unprofitable to recycle earlier, is expensive, and simply accumulated in the mines, will now go into business with a positive balance.
