7 thoughts on “Building A Block With a Sodium Reactor”

    • And what is wrong with helping Iran?

      Israel understands that once Iran has nukes there will be a stalemate in the Middle East, because Israel will not have free reign anymore.

      • There is already a stalemate, Israel has not threatened to “wipe iran off the map” like iran has done.
        Get a grip.

  1. I did my best, but still failed to figure out how does this construction site in th Urals region… may help out Iran

  2. This is a sodium cooled reactor, it was built in Beloyarsk. I think it went critical a few months ago. The pictures are really interesting, unfortunately like on so many articles on Englishrussia there are not enough explanations help a layperson understand what is what.

  3. True, I would like to see more about how this sodium reactor works. But,I can look that up. Much of what happens in a operating nuclear power plant is kept away from public eyes for whatever reason – safety? I am curious if Russia will ever consider the liquid thorium fuel reactor. Maybe there is some design bureau from the Soviet times that has now become a Russian Company that is developing a Liquid Thorium-Fluoride Reactor. I’ve seen some video’s on the technology. The Liquid Fluoride-Thorium Fuel Reactor needs fuel like Pu and U to start the nuclear chain reaction. Since the Thorium fuel cycle uses these radioactive materials to start the fission process it consumes radioactive materials depleting them down to isotopes with much shorter half lives; thus, reducing the storage times for spent fuel – saving money – and using spent fuel previously considered nuclear waste and using it as a valuable fuel source. (I ‘m not trying to pitch any company here. If I did it would be a canadian one. LOL.) The point is there is a peaceful contrubution to nuclear science here that is missing the participation of Russian science. This technolgy is safe. Moreover old nuclear material such as the “pit” – the nickname for the atomic bomb cores that are unuseable because they are past their useful life span for use missiles can be adapted for use as fuel in this reactor and consumed as fuel. Using Pits as fuel in a LTFR removes the need and cost to Russian Aerospace – Missile forces to have to find secure storage for such materials. Diplomatically Russian can receive international credit for achieving nonproliferation goals while making energy to sell, heat homes or use in their Industries while saving oil and gas for export sale while still providing the russian people with affordable energy.

    Because the LTFR is operates in the liquid phase the nuclear chemistry required to separate then recycle fissile material is simplified. Chemists need only to perform liquid-liquid separation extractions to isolate usable isotopes. All the chemistry can be done in the liquid state because thorium-fluoride salts (Thorium Tetra Fluroide)liquify at 1,110 °C.

    Because ThF4 is liquid at 1,110°C there is a lot of heat to generate steam in order to derive a steam turbine generator. The waste heat alone would be enough to heat a small town. The best part of using ThF4 is that its operating temperature is well above the boiling point of water with out the worry of a secondary water coolant overheating and breakingdown into hydrogen and oxygen at high temperature. The safety of the LTFR fuel circuit is unparalled, in the event of a Power Spike the reactor can be scrammed to subcritical by draining the liquid fuel circuit into containment tanks. The plugs separating the primary liquid fuel circuit are simply frozen He-plugs and maintained at operating reactor temperatures above that the plugs melt away and automatically scram the reactor halting the fission reaction – elimininating the danger of meltdown.
    One technical problem requiring unique Russian ingenuity is metallurgy. You see liquid throium salts are highly corrosive so the liquid thorium-fluoride fuel mixed with U235 needs to flow in metal tubes that remain strong and corrosian resistant at high temperatures and in the presence of radiation. Russian scientists conquored similar technical challenges when they developed their rocket motor progams. Metal parts such as rocket motor combustion chambers had to remain strong and resistant to extream heat when rocket motors were ignited (burning) moreover the metals selected needed to be chemically unreactive when the fuel material was in contact with them during combustion process. Russian science has, I believe, a great deal of knowledge skill and ability here. The technical challenges are solvable the problem. So I’d love to see if Russian Science is helping toward this wise and peacful application of nuclear science loaded with puzzles that bright minds love to solve.
