367: Material conception of the first wall

With Xiao Xin's cooperation, the blood collection went smoothly.

The next step was gene separation, re-isolating the giant rat's serum protein and gene protein.

Three days passed in a flash.

Guo Hao's eyes were full of excitement.

During these three days, with the help of Xiao Xin's robotic arm, Guo Hao almost completely dissected the giant rat again.

The genes of this giant rat had undergone a huge deviation at the level of the rodent family.

It wasn't atavism!

It was evolution! Or perhaps mutation would be a more fitting term.

The proportion of the gene chain belonging to rats within this giant rat was not very high, and its gene compatibility with the rat population did not exceed seventy percent!

This could be said to be quite astonishing!

According to the definition in genetics, generally speaking, the degree of gene compatibility among all organisms in the biosphere, specifically among mammals, exceeds eighty percent!

Seventy percent is usually the genetic difference between mammals and birds!

It was completely across species!

The genetic mutation had reached the level of crossing species!

Amazing!

Guo Hao's eyes were full of satisfaction.

Reaching this level indicated that the Type 2 gene agent was even more potent than he had anticipated!

With this thing, his research on corresponding organisms and genes could become more in-depth!

Guo Hao was slightly excited.

Not only that, he also found some traces of gene enhancement on this giant rat, which might be used for the development of Type 3 gene agents.

In Guo Hao's vision, simple gene mutation was not his pursuit.

What he pursued was a type of gene enhancement similar to life water.

But judging from the current research results, all of this still had a long way to go.

Thinking of this, Guo Hao sighed slightly.

This thing couldn't be solved anytime soon, so Guo Hao injected the Type 2 gene agent into several other organisms, including insects, birds, snakes, and other mammals.

After injecting the agent, Guo Hao had Xiao Xin closely monitor the mutations of these organisms.

Having finished these tasks, Guo Hao continued to worry about the material for the first wall.

News came from the Controlled nuclear fusion reactor side that, except for the first wall, all other parts had been repaired.

The next step was the material for the first wall.

The high-temperature resistance and neutron irradiation resistance of tungsten alloy were actually quite good.

But the problem remained the same.

Heat accumulation and metal fatigue.

Then there was neutron irradiation, the continuous particle bombardment, which was also a major problem.

tungsten alloy... couldn't withstand it.

According to Guo Hao's calculation results, perhaps tungsten alloy, under optimal proportioning, could withstand it for a period of time, maybe a few hours.

But... one day, two days, or even one or two years.

Guo Hao had no confidence in this material.

The plan used by ITER also did not use tungsten alloy.

They used beryllium armor plates covering the plasma-facing area, withstanding a steady-state heat load of 4–5 MW/m², maintaining the surface temperature at 500°C–700°C through water cooling.

Tungsten was used as the divertor, and a copper-chromium-zirconium alloy heat sink was employed, combined with water cooling to achieve efficient heat dissipation.

Beryllium armor was the core.

Combined with water cooling for heat dissipation, this was indeed a good solution.

But according to Guo Hao's modeling and mathematical calculations.

Their plan, when the time was short, for example, within half an hour or an hour, would not encounter too high a neutron bombardment intensity.

The transient temperature would not last too long either.

So, basically, there was no problem.

But for a longer time... it was almost the same as the tungsten alloy solution he was currently using.

Unreliable.

Cooling and heat dissipation were also needed, and at the same time, the problems of heat accumulation and neutron bombardment needed to be resolved...

The problem of transient temperatures exceeding five thousand degrees also needed to be solved...

Hmm...

Guo Hao pondered for a moment.

He was actually very optimistic about the direction of phase change materials absorbing transient thermal shock, but the drawbacks of this type of material were also significant.

Long-term, stability.

It was a bit too difficult!

Perhaps it could only be solved from the perspective of nano-coating.

At this moment, Guo Hao suddenly remembered the stealth coating material he made for the fifth-generation aircraft, the high-temperature resistant nano-coating material!

Perhaps this was also a very good angle!

The material for the first wall might not be that complicated!

Using oxide dispersion strengthened steel combined with a coating of nanocrystalline tungsten.

Although nanocrystalline tungsten is prone to embrittlement at high temperatures, nanocrystalline tungsten can also be synthesized again!

Guo Hao recalled the problems he encountered when making the stealth nano-coating material for the fifth-generation aircraft.

His eyes revealed intense excitement.

Maybe it could work!

Oxide dispersion strengthened steel, abbreviated as ODS steel, can operate at temperatures up to 700°C, is superior to traditional stainless steel, has high inherent strength, and can also suppress void swelling caused by neutron irradiation.

The effect is actually quite good, but it cannot resist transient high temperatures exceeding five thousand degrees.

Even with the help of the cooling system, it is still not enough.

Therefore, coating can solve this problem!

He quickly sat down at a nearby table and began rapidly calculating and designing the coating material.

Over the next dozen or so days.

Guo Hao had the Controlled Nuclear Fusion Center change the material of the first wall, all to ODS steel, and then use tungsten alloy as the casing, along with the coating material.

Another experiment was conducted.

The duration of this experiment increased by another dozen minutes compared to before, demonstrating some of the excellent neutron bombardment resistance properties of ODS steel.

But similarly, even with the support of the cooling system, the ODS steel inside the casing still experienced some melting.

He began to slightly modify some of the ODS steel formulas, the ratios of various elements.

Over the course of a month, Guo Hao conducted experiments multiple times and performed mathematical modeling calculations on the coating material.

Yan Aviation.

Inside Guo Hao's office.

"What do you think our Professor does all day... so mysterious..."

Zhang Yiyuan asked Wu Bo next to him somewhat helplessly.

"It's been two months since school started, and the Professor only gave us a class at the beginning, and then a long time passed... He hasn't given us any classes since then!"

"It's normal, Guo Hao is busy with affairs, it's normal for us students not to get attention, he's probably working on some earth-shattering topic again!"

I still remember when Guo Hao solved Goldbachs Conjecture, the world truly trembled for a moment! It was amazing!"

"That's true!"

Hearing Wu Bo's answer, Zhang Yiyuan nodded.

"You know, meeting a Professor like this, I don't know..."

As he was speaking, Zhang Yiyuan suddenly stopped, because he saw Guo Hao at the door.

"Just the two of you? Where are they?"

Guo Hao looked at the two and asked.

"They... I don't know..."

Wu Bo said somewhat hesitantly.

"Call them all over, come to the Laboratory!"

Guo Hao said calmly.
