Dual Fluid Reactor - Youtube commentator gives exciting information

Recently I am again at the Science Youtube Channel Norio stumbled across a video, where I thought to myself again, man, you know this already. And so it was, it was about the topic of the dual fluid reactor, the advantages but also the disadvantages.

The Dual Fluid Reactor is produced by the company of the same name Dual Fluid Energy Inc. developed. The directors: Dr. Armin Huke, Dr. Götz Ruprecht, Prof. em. Ahmed Hussein, Dr. Titus Gebel, are competent in the field of nuclear physics (not so apparently the Greens, who themselves dismiss this solution as bullshit, without having dealt with it), according to the information I could find about the people.

Here is a picture of how this is constructed and how it works, instead of water lead is used, which avoids a hydrogen explosion like in Fukushima. Due to the thermodynamic laws in such a liquid fuel system, the density of the material is reduced during expansion, where the reaction is reduced, so the system can regulate itself and if something should happen, the fuel is collected until it is solidified.

And occasionally you have the odd thought provoking comment there and these would love to share here, of course I asked the author of the comment for permission and he was happy for me to share it further:

The point of his comment was that Zirconium carbide as a coating have the best properties for a dual fluid reactor. As early as the 1960s, research was carried out at the Oak Ridge National Laboratory in the USA on a dual fluid reactor and the conclusion was reached that this was not practicable. However, discussions today do not take into account that the materials industry and research have developed further and that there are alloys today that did not exist back then or that one did not even dare to dream of back then:

Despite its good properties, zirconium carbide is currently only used for coatings on fuel for nuclear fission and fusion reactors. The reason for this is its high price. One advantage of zirconium carbide is that it interacts almost not at all with neutrons. Because of the presence of carbon - a relatively good neutron moderator - zirconium carbide is more suitable than metallic zirconium for some applications from a nuclear point of view. The melting point of zirconium carbide is 3540° C and the boiling point is 5100° C. Because of its corrosion resistance, zirconium is of great importance in chemical plant engineering. Because of its low capture cross-section for thermal neutrons, i.e. its high neutron permeability and other favorable properties, zirconium carbide is suitable for nuclear reactors and even fusion reactors. Conclusion: Silicon carbide and zirconium carbide, as well as refractory metals, are extremely expensive, but have excellent material properties that enable the construction of a dual-fluid reactor. Although these HiTec materials are very expensive, the cost remains the same compared to a conventional second- and third-generation nuclear reactor because the DFR does not require expensive apparatus and equipment to cool the reactor because its liquid nuclear fuel and the laws of thermodynamics allow the DFR to regulate itself - and it does so much faster than with graphite rods in the old types of reactors with solid fuel rods. Conclusion: Silicon carbide and zirconium carbide can be used in large quantities in the reactor construction of the DFR, since the expensive and maintenance-intensive cooling systems of the reactor are no longer required and the expensive HiTec materials with their excellent properties can be used instead.

Also worth sharing:

The benefits of the Dual Fluid Reactor are indeed stunning and amazing:
+ all actinides from a core number of 232 (thorium) can be used

+ both natural uranium (U-238) and the uranium-238 present in the "nuclear waste" can be used as fuel

+ Fuel is in liquid form in a separate closed circuit

+ in the second circuit circulates liquid lead, which practically cannot become radioactive, is a good conductor of heat, has a low melting point and a very high boiling point, also has exceptionally good corrosion resistance, is a good neutron scavenger and shields X-rays and gamma rays very well (significantly increased safety and significantly increased efficiency of the reactor)

+ Operation at normal pressure; no overpressure required (also significantly increased safety)

+ Operation without water, therefore no overheating of water and the associated thermochemical generation of hydrogen possible (omission of water increases safety; no strain on a natural resource)

+ No expensive cooling systems necessary, as the reactor is self-regulating and behaves like a self-regulating thermostat (according to the laws of thermodynamics).

+ no expensive preparation of the actinides necessary

+ nearly 100% of the energy at rest in the actinides is used to generate clean electricity and process heat for industry (the process heat enables the thermal generation of hydrogen, so no energy-intensive electrolysis is needed to produce hydrogen - low-cost production of clean hydrogen in large quantities).

+ after 100 years 90% of all actinides are free of radioactivity, the remaining 10% after about 300 years (for comparison: the nuclear waste produced so far has to be stored safely for at least 100,000 years...).

+ high-purity rhodium and high-purity molybdenum-99 are transmutated/"incubated" in small quantities (rhodium is probably the rarest and also most expensive precious metal on our planet, has special properties such as low reactivity and high catalytic activity and is required for special alloys; high-purity molybdenum-99 is required in nuclear medicine, especially for imaging procedures, for the diagnosis and detection of diseases and in radiation oncology for the therapy of tumors).

+ scalable reactors possible ex works, depending on application, performance requirements and demand

+ very low space requirement

Take existing nuclear waste, i.e. old reactor rods, grind them like coffee beans, put this "nuclear waste" into the dual-fluid reactor and the existing nuclear waste becomes a valuable material that still contains an incredible amount of energy. And clean electricity is generated from it. Add to that high temperatures, temperatures that are necessary to split water thermochemically into hydrogen and oxygen - without energy-consuming electrolysis. And already we have incredibly large amounts of clean electricity, large amounts of process heat and huge amounts of hydrogen, with the pleasant side effect that the nuclear waste is no longer radioactive at all after about 300 years - and the residual radiation is even less than that of natural uranium and natural radiation. So what is stopping us from wanting to build this almost magical dual-fluid reactor? Do we want power outages due to weather-dependent photovoltaic systems and wind turbines? Do we want to keep mining lithium (and emitting vast amounts of CO2 in the process) to build batteries instead of using hydrogen as an energy source? Do we want to continue turning salt water into fresh water with electricity-guzzling reverse osmosis when the process heat can be used to turn salt water into drinking water? And finally: Why does ignorance want to triumph over reason?

I do not want to start a discussion at this point that I only list the advantages of a commentator, of course there are also disadvantages, but if you consider the number of advantages you get and that a GAU can be excluded due to physics and thermodynamic laws. So why does a German company leave Germany? Well, Germany doesn't have it so with nuclear energy.... unfortunately.
