"There are only a few powerful countries in the world that have the strength to study this thing, such as the United States, Russia, the European Union, and Neon! However, they are still in the experimental exploration stage, and they are still very far from application, and it can be expected that if our plan can be completed on time, then even if other countries begin to catch up with each other, we can still maintain a monopoly position for fifteen to twenty years!" After speaking, Lu Qiujian began to introduce him to the controllable nuclear fusion devices of other countries!

"Now there are mainly such major devices in the world: the United States TFTR tokamak device, the United States national ignition device NIF, Lucia's T20, which later shrank to T15, the coil is smaller, but on the superconductivity, neon JT-60 device, European Union Ring JET, International Thermonuclear Reactor Program ITER, in addition to France's Tore-Supra, Germany's Spiral Stone-7, and of course, China's newly built Oriental Superring EAST!" The last of these items, due to the Xihe plan led by Lu Qiujian, will probably only be used as a cover to attract foreign attention for a long time to come.

Qin Feng took the teapot and filled Lu Qiujian's teacup, and motioned for him to continue, "I will briefly talk about the current situation and expectations of several more important nuclear fusion devices; first of all, I will first talk about the two large devices in the United States, the TFTR tokamak device and the national ignition device. ”

"As the name suggests, the TFTR tokamak device is a kind of Tukemak device, which is a kind of nuclear fusion device that adopts a toroidal magnetic field for magnetic confinement, which was first built at the Kurchatov Institute of Atomic Energy in Lucia, and the name is an abbreviation of the prefix for ring, vacuum, magnetism, coil and other words in Russian!"

"TFTR was built by Princeton, completed and put into operation in 82 years, and has achieved a series of achievements, such as plasma confinement, heating, tritium treatment, D-T neutron activation and other fields have accumulated valuable experience, but the scale of this device is relatively small, and only some theoretical verification work can be carried out. If you want to make a bigger breakthrough, you can't rely on this gadget alone!"

"As for the construction of the national ignition device from 97 years, a total cost of 3.5 billion US dollars; it is expected to be completed in 09 years; it is the world's first large-scale device with inertial confinement fusion as the main goal; according to the design, the national ignition device can use the laser with a total energy of 2MJ as the driving source to drive the deuterium-tritium target pellet, and for the first time realize that the output fusion energy is greater than the energy in the core area of the input target pellet, this achievement is a milestone, marking a historic step towards the development of controllable inertial confinement fusion energy for mankind. But it will be a long time before they reach this goal, and according to my estimates, this experiment will probably not be completed until 13 years, and by that time the Xihe Project will have achieved this goal long ago! There are certain problems in the design of the national ignition device, and the energy output it can obtain will be far lower than the expectations of the scientists in the United States, they plan to get 20 megajoules of energy output through this experiment, and the result I calculated is that they can only get 20 kilojoules of energy output, which is a thousand times worse than their original plan!"

"Neon's JT-60 device was built in 85 at a cost of about 15.3 billion yuan, and the transformation and upgrade was completed in 91, after which experiments were carried out around the improvement of restraint performance and steady-state operation. The aim was to study the steady-state operation of the tokamak unit by improving the plasma confinement performance; It has achieved the highest values in the world in terms of energy gain factor, plasma temperature and nuclear fusion triple product, which is very good, but these are the results of the last century, and it is now mainly doing basic research work for ITER. ”

"The European Union Ring was once the world's largest fusion reactor, built in 1984 in Oxford, England. The research team led by Dr. Westel from Germany, Dr. Lebi from France, Dr. Kyle Hacker, Dr. Zaque, and Dr. Pamela is currently in charge of Dr. Francisco Romari from Italy. But these are the top scientists in the field of nuclear fusion in the whole of Europe, and under their leadership, the European United Ring has set a new world record for fusion performance!"

"At the same time, they also showed us the wrong path with their mistakes, such as in the condition of an all-metal wall. Fuel recirculation is greatly reduced, the dust accumulated during the discharge process is greatly reduced, tungsten impurities do not cause serious damage to the plasma performance, etc., Zhejiang allows us to save a lot of time and a lot of money. ”

"In recent years, due to the decline in reactor efficiency caused by the above mistakes, the shortage of EU funding, and the launch of the international thermonuclear reactor program, the funding of the European superring has been repeatedly cut, and it is predictable that they will be able to create another breakthrough!"

"Finally, let's talk about the most popular project at present, the International Thermonuclear Reactor Program! This program began in 1985 with the map head of the Red Empire and the Reagan Initiative of the United States, and spent more than 1.5 billion dollars to complete the preliminary design, and was officially launched and implemented last year!"

"I know this project, in 03, my country also participated in the negotiation of the plan, and signed a plan with the European Union, the European Union, India, Neon, South Korea, Lucia and the United States last year!" Qin Feng finally heard the project he was familiar with, he interjected, "Before signing the agreement, the Great Elder They were still hesitating, since we already have the Xihe plan, is it necessary to waste funds on this plan?"

"However, in the end, it was implemented according to the original plan, firstly, to prevent other countries from guessing the true intentions of the Xihe Plan, and secondly, to understand the thinking of scientists from other countries through participating in the plan, and to provide reference for the Xihe Plan!" Lu Qiujian also heard of this for the first time.

"This program can be said to be the nuclear fusion research program with the largest investment and the largest number of participants in the world at present, in addition to the Xihe program! If we only talk about the number of top scientists, the international thermonuclear reactor program will even surpass our Xihe program!" It is true that in recent years, China's scientific talents have continued to grow, but they are still far from these seven-party organizations.

"So our biggest competitor at the moment is the International Thermonuclear Reactor Program?" Qin Feng frowned when he heard the last sentence, "Xiao Lu, do you think our Xihe plan will progress faster than them?" )

PS: There is also a chapter of monthly pass additions, and I ask for a monthly pass at the beginning of the month.
