Vol 2 Chapter 444: Nuclear fusion reactor ignition experiment!

This nuclear submarine base needs a lot of electricity, and the lower level nuclear fusion reactor also needs a lot of electricity for experiments, so it is very necessary to build a nuclear fission reactor.
It’s not as I imagined that nuclear fusion reactor experiments are going to be carried out. Why do we need nuclear fission reactors? Not to mention other things, when a nuclear fusion reactor is ignited, a huge amount of energy is needed to supply the ignition device. Because to achieve a nuclear fusion reaction, the ignition temperature must exceed 100 million degrees. Without continuous energy, how can it be possible to ignite smoothly? carry out.
Moreover, the maintenance of nuclear fusion reactors also requires continuous power supply. The entire nuclear fusion reactors Lei Tiantang and Kuafu use magnetic confinement "tokamak devices". The strong magnetic field of this structure requires long-lasting strong energy. To maintain it.
Otherwise, if the nuclear fusion reaction loses its restraint during operation, the consequences can be imagined. In order to ensure that there will be no danger caused by possible power outages, Lei Tiantang has equipped the nuclear fission reactor with a large number of high-performance batteries. It is very necessary.
Because it is on the seabed, the cooling water needed by the supercomputer units is large enough, so this time Lei Tiantang does not need to find stable and continuous groundwater to cool them down.
Anyway, the seawater also takes away the heat in the cooling pipe, and there is no need to desalinate the seawater. For Lei Tiantang and the others, there are several kinds of materials to prevent seawater corrosion.
After Lei Tiantang completed the installation of the nuclear fission reactor, Kuafu had already connected the entire supercomputer unit, and he would just leave the rest of the work to him.
He needs to continue digging down. The nuclear fusion reactor laboratory is the focus. In order to ensure the safety of the laboratory, Lei Tiantang and Kuafu designed a frantic construction plan!
Like the nuclear submarine base above, when the entire nuclear fusion reaction base dug such a huge space, Lei Tiantang did not say that the rocks were collected, but used the absolute field to combine these rocks with the rocks on the walls of the base. Extreme compression!
Make the hardness of the entire base wall comparable to diamonds! And the thickness of the entire compressed wall reached 30 meters! Such a thick, high-strength rock layer allows the entire base to face an earthquake of magnitude 10 or higher, but it can also ensure the overall safety of the base!
In order to avoid possible radiation leakage from the reactor, the entire wall is covered with a 1-meter-thick radiation protection material. The entire material is the latest research by Lei Tiantang and Kuafu. In fact, it only needs 1 cm thickness to prevent radiation. One can imagine their madness!
In order to avoid the serious consequences of a possible explosion in a nuclear fusion reactor, Lei Tiantang and Kuafu designed a 5-layer high-strength buffer layer behind the anti-radiation material, each layer is densely packed with high elastic springs. !
These springs are densely connected together, and a high-strength flexible material is also used for the compartment between each layer of springs, which can further play a buffering role.
After Kuafu’s simulation calculations, with such a powerful buffer layer, even if the reactor exploded, it would destroy the nuclear fusion reactor laboratory at best, and the nuclear submarine base above would not suffer any damage!
After spending half a day, Lei Tiantang finally completed the construction of these complicated designs, and all the reserved passages were completed.
Finally, Lei Tiantang cautiously placed the nuclear fusion reactor that was built a long time ago in the center of the laboratory, and then, together with Kuafu, connected the reactor and laboratory pipes and various connecting cables and other equipment together.
The whole work has lasted for nearly a day. After all the installations are completed, Lei Tiantang carefully checked it again, and finally hissed: "Finally completed, the rest of the work is left to you!"
"Good boss, after the reactor has completed the self-check, if it is in good condition, then the ignition experiment can be carried out. Do you need to leave the subsea base?" Kuafu asked as usual.
"Then start the self-check according to the process and start the fire if there is no problem! As for I don't have to leave, the entire base is the safest when I am here!
With my control, even if there is an accident in the reactor, I can instantly stop the accident from happening, so as not to blow up our newly built base! "Lei Tiantang said with a smile.
"Good boss! Then I will start self-checking and filling up the coolant!"
"The superconducting coil is energized normally!
The liquid nitrogen coolant starts to be filled!
The power supply system of the whole system is tested normally!
The ring vacuum chamber is tested normally!
The laser ignition device is normal!
......"
While Kwafu was testing, he reported to Lei Tiantang that the part was detected. Hearing the voice of one item passed, Lei Tiantang's mood was both nervous and happy.
After busying with Kuafu for such a long time, he finally completed the design and manufacture of the entire nuclear fusion reactor. The difficulties encountered during the entire research and development process are simply countless!
The overall structure of the nuclear fusion reactor itself is very complicated, and there is no successful international experience for Lei Tiantang to learn from. Those reactors that can only run for about 100 seconds after ignition are not mature designs.
So the current nuclear fusion reactor began to condense the efforts of Lei Tiantang and Kuafu! It can only be re-studied based on those immature designs, UU Reading www. Many theories of uukanshu.com need to be verified one by one, especially in the research and development of various materials!
At present, the high-performance materials used in nuclear fusion reactor laboratories in various countries in the world, such as superconducting materials and anti-neutron radiation materials, cannot meet the requirements of real nuclear fusion reactions.
This is also the reason why those reactors can only last for such a short time, especially for anti-neutron radiation materials. Each deuterium-tritium fusion will produce a 14MeV neutron. These high-energy neutrons can easily break the metal in the first wall material. Bond, produce a lot of defects, cause radiation swelling, embrittlement, creep and other problems, making the material completely unusable.
Therefore, the development of new anti-radiation materials is the biggest problem they face, because if this problem cannot be solved, the nuclear fusion reaction cannot be used for a long time.
And because the material of the first wall needs to face the continuous bombardment of neutrons, many elements will undergo nuclear reactions and transmutate into other nuclides. Some nuclides are unstable and will continue to decay and emit radiation.
In this way, the advantage of non-radiative pollution products of the fusion reaction is gone, so the materials used as the first wall are all low-activation materials, that is, elements that are stable and non-decay after transmutation.
