Chapter 224 Deuterium-Tritium Fusion Reactor!
"The temperature continues to rise..."

"1500 degrees..."

"5000 degrees..."

"7000 degrees..."

"1 million degrees..."

"1.2 million degrees..."

"The plasma is functioning normally..."

"The reaction begins!"

"Heat transfer is normal..."

"The steam cycle system is functioning normally..."

"The generator is on!"

"The power generation is normal..."

"The Q value is already greater than 1, and the energy output is greater than the energy input..."

"The Q value continues to grow steadily!"

"The Q value exceeds 5!"

"8!"

"10! More than 10!"

"it is good!!"

The control room erupted instantly.

"Wow—"

Everyone clapped excitedly. The controllable nuclear fusion that they had been dreaming about for so many years finally came true today.

And not only has controllable nuclear fusion been realized, but also controllable nuclear fusion with a Q value exceeding 10, which means that controllable nuclear fusion is commercially available!

But they are happy, but Li Future is thinking about the problem.

Of course he is also happy, but not that happy, because the current Dongfang Chaohuan controllable nuclear fusion reactor is not commercially available, and it is not that powerful.

After all, what the Eastern Superring achieves is deuterium-tritium fusion.

In his opinion... not so good.

The deuterium-tritium reaction is a nuclear fusion reaction produced by colliding deuterium nuclei with tritium nuclei. It is the easiest of all nuclear fusion reactions to occur, and it only needs more than 1 million degrees.

Moreover, the earth's seawater contains more than 40 trillion tons of deuterium, which is enough for human "extinction".

However, it also has its problems, that is, there is almost infinite amount of deuterium on the earth, but almost infinitely little tritium, only a few catties in total.

Fortunately, there is very little tritium in nature, but humans can make it artificially.

Tritium is produced by bombarding lithium with neutrons.

In industry, people will use the neutrons of the reactor to bombard the target made of lithium-6 compound to produce tritium, and then use the thermal diffusion method to enrich the tritium to more than 99%.

Coincidentally, the deuterium-tritium reaction can produce a large number of neutrons, and then allow these neutrons to bombard the lithium-6 target to multiply the tritium, thereby achieving tritium self-sustainability.

The current known reserves of lithium are sufficient for thousands of years, and there is basically no fuel shortage problem.

However, the neutrons produced by the deuterium-tritium reaction not only bring benefits, but also bring harm, that is, neutron radiation.

When neutrons interact with matter, they mainly interact with the nuclear force in the nucleus, and do not interact with electrons in the outer shell.

Neutrons have a strong penetrating power when passing through matter, and the danger to the human body is more serious than that of X-rays and γ-rays with the same dose.

After the human body is irradiated by neutrons, the intestines and stomach and male gonads will be seriously damaged, the biological effect of inducing tumors is high, and it is easy to cause early death.

At the same time, the damaged body is susceptible to infection and the degree is severe, and the relative biological effect of eye lens opacity is 2 to 14 times that of gamma or X-rays.

It can cause hematopoietic organ failure, digestive system damage, and central nervous system damage.

It can also cause malignant tumors, leukemia, cataracts, etc.

Even neutron radiation can produce genetic effects, affecting the development of offspring of those exposed to radiation.

Humans have taken advantage of these properties to create neutron bombs, which can kill armor protection and people inside buildings within an effective range.

Those who were killed did not die immediately, but died slowly and very painfully. The wounded could be delayed for up to 7 days without medical treatment.

Moreover, the duration of neutron flow is very short. For battlefields attacked by tactical nuclear weapons such as neutron bombs, one's own side can quickly enter the target area to fight without worrying about radioactive pollution.

This is much stronger than the average atomic bomb.

However, in the deuterium-tritium fusion reaction, neutrons are continuously produced, so protective measures must be taken.

Of course, fusion is still fusion. The neutrons produced by deuterium-tritium fusion reactors are already much less than those produced by fission reactors, which is relatively "cleaner".

However, there is one thing similar to a fission reactor, that is, 80% of the energy of the deuterium-tritium reaction will be taken away by neutrons, and the neutrons are not charged, so the way of deuterium-tritium fusion reactor power generation is...burning, boiling, and water!

Of course, the same sentence: "Fusion is fusion after all!"

It is also "boiling water", the efficiency of nuclear fusion is much higher than that of nuclear fission.

So is there any nuclear fusion that does not boil water and directly generates electricity in science fiction movies?
Of course the answer is: yes!
That is deuterium and helium-3 fusion.

The reaction products of the reaction between deuterium and helium-3 are charged particles, and through charged particles, it is possible to skip the use of inefficient steam cycle systems and directly convert nuclear energy into electrical energy.

And the energy released in this reaction is very, very, very large!

Another advantage of the reaction between deuterium and helium-3 is that no neutrons are produced, or only very, very few neutrons are produced, almost none
This is actually much cleaner than the deuterium-tritium reaction.

If the deuterium-tritium reaction produces neutrons and requires "boiling water" to generate electricity, it belongs to the first generation of controllable nuclear fusion technology.

Then the reaction of deuterium and helium-3 does not need to boil water, can directly convert nuclear energy into electrical energy, and does not produce neutrons, or produces very few neutrons, then it is the second generation of controllable nuclear fusion technology.

However, there are many problems in the reaction between deuterium and helium-3. One of them is that the temperature it needs is too high.

The deuterium-tritium reaction only needs more than 1 million degrees, and the temperature required for the reaction between deuterium and helium-3 is directly increased by ten times, requiring more than one billion degrees!
When the temperature reaches this level, it is not something that can be solved simply by improving the magnetic confinement capability. All parts of the reactor must be redesigned, and a large number of new technologies are required.

Fortunately, these technologies can also be provided in the future, but it will take a little time.

In addition, helium-3, like tritium, is almost non-existent on the earth, and even it cannot be artificially prepared.

Or it can be prepared, but humans do not currently have that kind of technology.

But there is a huge amount of helium-3 in one place, and it is the same as deuterium in a spoonful of water in the sea, which belongs to the kind that can be found in a handful of soil.

That place is - the moon!
And now there is a practical technology outpost test module and a dozen lunar rovers on the moon.

The starry manned moon landing plan is also obvious, it is to explore the possibility of long-term human presence on extraterrestrial planets, and the possibility of large-scale production of helium-3.

Back at the scene, when it was confirmed that the Dongfang Super Ring was operating normally, all the people at the scene signed a non-disclosure agreement, and then they had a dinner party and went back to their respective homes.

During the period, Mr. Jin told Li Future about the energy distribution of the Dongfang Chaohuan Reactor.

As an experimental reactor, the Dongfang Super Ring is still a small experimental reactor. Its power is not large, but because of the characteristics of nuclear fusion, it is enough to support some special usage.

First, it will allocate part of the power generation to support several high-energy-consuming experimental centers of the Academy of Sciences in Greentown.

The other part will convert a state-owned hydrogen production plant into a metal hydrogen production plant, which can remove part of the cost of metal hydrogen.

At present, more than 95% of the metal hydrogen in Fanxing is produced there, and it is also the only factory for the industrial production of metal hydrogen. Whether it is solid metal hydrogen used in military affairs and special equipment, or liquid metal hydrogen used in practical science and technology aerospace companies, all come from There.

Moreover, a larger nuclear fusion experimental reactor is under construction not far from Science Fiction Island, and it has been under construction for more than a year.

Although there are new indicators that need to be improved now, after working overtime, it will take about one year for the ignition to run.

At that time, the cost of preparing liquid metal hydrogen can be reduced by a large amount!
