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.
