"Yashan!"

"Little dream, Zhang Qing!"

At noon the next day, in the core area of the demonstration reactor of the Yangcheng laboratory, Li Yashan, who had been authenticated, walked in.

At the moment when they saw Li Yashan, Lin Meng and Zhang Qing put down the things in their hands for the first time, ran over and everyone was holding hands to catch up on the old days, and Lu Yi, who was wearing protective clothing, frowned.

He knew that because they wore protective clothing all day long and stayed in the core area of the demonstration reactor to participate in the construction task, Zhang Qing and Lin Meng usually wiped skin care products after washing their faces, but today they heard that Li Yashan was coming, and both of them got up early and put on makeup carefully, and they didn't do any work......

Women, they're superficial animals!

Lu Yi sighed in his heart, but he didn't dare to let him go over to join in the fun, took the design plan into the dust-free core area that had been shrouded and isolated, and explained to the engineer who was assembling the stellarator: "Pay attention to the precision during installation, carefully calibrate with a laser calibrator, and then check each other after completion, this thing is more expensive than your wife at home." ”

"Chief Engineer Lu, we are all single dogs, just waiting for your introduction."

The engineers below who were wearing full protective suits smiled very easily, but the technology in their hands that had been trained in the construction of multiple fission reactors was unambiguous.

"Okay, the construction of the demonstration reactor is completed, I will take you to the Tomorrow Group for a few rounds, with an annual salary of hundreds of thousands, and participated in the construction of the world's first nuclear fusion reactor, I believe that I can fascinate a group of young ladies."

Lu Yi didn't get the slightest jerky when talking about this topic, he knew that with these engineers who were struggling on the front line, talking about these topics was the best way to win people's hearts and shorten the distance.

Anyway, outside, Lin Meng, Zhang Qing, and Li Yashan didn't wear protective clothing, so they couldn't come in, right?

"I'm looking forward to the words of the chief engineer of landing."

An engineer finished assembling a component, and after interchanging with the person next to him to inspect the installation of the other party, he pointed to the space required to be set aside and asked: "Chief Engineer Lu, will the space reserved for the first inner wall be a little larger, so that the rear structural layer may be very reluctant." ”

"The first layer of beryllium ceramic alloy is 3.16 mm, plus a composite layer of carbon nanomaterials and nano-ceramics, the first inner wall is a little thicker than the original tomorrow stellarator, but no problem, this stellarite has enough room for improvement when it is still WEGA."

Lu Yi nodded, the deceleration of beryllium on neutrons is proportional to the thickness, if the thickness of the first layer of beryllium ceramic alloy material is increased to 3.16 mm, then the neutron deceleration will consume more energy, and the neutron irradiation intensity of carbon nanomaterials and nanoceramics will also be lower, and the final persistence time can reach more than 8 years.

"3.16 mm, there is no problem with the heat generated by neutron deceleration, right?"

The engineer asked curiously just now, they have built many fission reactors, and sometimes they don't need to ask the researchers, they can click and click as soon as they look at the drawings.

But fusion reactors? See you for the first time in your life.

"No problem, all the parameters are strictly calculated, everyone can strictly construct according to the accuracy of the drawings, and replace each other and check each other after each step is completed."

Lu Yi stepped forward and randomly checked the installation of several components, and explained again.

The elite mobilized by this group of nuclear industry groups have participated in the construction of multiple fission reactors, and the rigor and technology can be guaranteed, and the relevant plans have been trained several months ago.

It stands to reason that Lu Yi only needs to solve some problems that they don't understand and don't understand the final plan, and the rest should be at ease.

It's just that at present, there is only one pressurized water reactor core, that is, a real nuclear fusion reactor, which is improved on the basis of tomorrow's stellarator.

Having thoroughly understood the technology on the stellar simulator of tomorrow, theoretically it is not impossible to make stellar simulators in China, but in fact, the stellarizers involve some high-precision components, but they can only be processed by the top batch of industrial machine tools in China.

It is difficult to describe the cost, problems, and time involved in letting these top industrial machine tools throw away their original tasks and turn to the manufacture of stellarics.

Therefore, the construction of the core area of the demonstration reactor must be foolproof, and there will be no second chance in a short period of time.

After more than two hours of completely sealed dust-free construction, some problems that the engineers did not understand were solved, and Lu Yi saw that everything was going well, so he walked outside.

"Chief Engineer Lu, Chief Engineer Lu!"

Li Yashan and the three of them were no longer outside, and just as Lu Yi was about to take out his mobile phone to make a call to ask where he was, a middle-aged fat man next to him who had no permission to enter the core area and was squatting on the ground saw Lu Yi coming out and hurriedly shouted a few times.

"Mr. Pan, what's wrong?" Looking at the boss of the R&D and Construction Department of the Nuclear Industry Group who suddenly appeared, Lu Yi asked a little strangely.

"Chief Engineer Lu, I just want to ask, what kind of plan is the ferrofluid power generation you mentioned before?"

Mr. Pan asked with a smile on his face: "Now that the demonstration reactor plan has been finalized, our construction engineers have work to do, but the brothers in charge of the scheme design are idle and panicked, and I wonder if I can find something for them to do." ”

"Let them continue to design and study the fourth-generation fission ...... Forehead! ”

Lu Yi realized what he had overlooked halfway through speaking, with nuclear fusion reactors, fission reactors that are unsatisfactory in terms of safety, cost, and power have entered the brink of elimination.

After being silent for a while, Lu Yi shook his head and said: "The ferrofluid power generation plan may have a big impact, call everyone to the conference room, and I'll talk to them about it." ”

"Alright, I'll let those boys come over now."

Mr. Pan seemed to realize something, and his expression was a little apprehensive when he was still happy a moment ago, and hurriedly walked to the narrator, took out his mobile phone and called someone from his team to come over.

Behind him, Lu Yi took out his mobile phone and looked at the time, and with a somewhat helpless expression, he sent a message to Lin Meng and the three of them to briefly explain the matter, saying that they would probably be busy for about an hour.

Originally, Li Yashan came over today, and he planned to take time to accompany Li Yashan and them to go shopping in the afternoon, but now it seems that it is already evening to get this thing done.

Fifteen minutes later, in the largest conference hall of the laboratory, a group of backbones of the Research and Construction Department of the Nuclear Industry Group sat on chairs and looked at Lu Yi like good babies.

"I know that everyone has been waiting for me to give the technical framework and attention to the details of the ferrofluid solution, and I already have a rough plan, so you can take a look."

Lu Yi turned on his computer and connected it to the high-definition projector, and projected two three-dimensional structural drawings with a large number of parameter data.

"The first one is the three-dimensional structure of the fusion pressurized water reactor program, have you noticed this area?"

Lu Yi projected a three-dimensional structural diagram of the core area of the demonstration reactor, and moved the mouse to a special location marked with a large number of parameters and circled it.

In a normal fissile pressurized water reactor, it encloses the entire core, which is the nuclear reactor, but it does leave a gap here, like an O becomes a C.

"This gap corresponds to the deflector area of the stellarumer, and the improvement on the stellarator has left room for subsequent transformation.

When the ferrofluid scheme matures, we will shut down the reactor and replace it with a new deflector to separate and filter the high-temperature plasma helium produced by nuclear fusion, which is the energy source for ferrofluid power generation. ”

Lu Yi enlarged the details inside the gap, this part of the structure and the parameters involved were all changed by Lu Yi and Lin Meng in the later stage, it was a new plan, and it was the first time for everyone present to see it.

The complex structure and densely annotated parameters make ordinary people look at it and their brains are expected to be dazzled and their brains swell, but in the eyes of this group of engineering dogs of the nuclear industry group, they are as intoxicating as sexy fruit girls.

"Chief Engineer Lu."

An engineer looked at the structure with low-thick glasses from a beer bottle and asked, "Can our deflector achieve this level of separation?" ”

The current PWR scheme of the demonstration reactor was determined by the joint research of the nuclear industry group and Lu Yi, and during this period of participating in the research of the demonstration reactor scheme, they have an in-depth understanding of the deflector of the nuclear fusion device.

Separate the helium nucleus alone, and return the heat flow and particle flow in the plasma, will this one deflection performance be too rebellious? If you knew that the temperature was as high as 100 million degrees Celsius.

"The deflector can't do it to this extent, you misunderstand what it means."

Lu Yi shook his head, double-clicked on the second rough plan of the overall structure of the ferrofluid to enlarge it, and said: "After the ferrofluid scheme is applied, in addition to the deflector will return the deuterium and tritium elements, the remaining helium nuclei and heat flows generated by fusion will all be sent into the ferrofluid power generation channel.

In other words, most of the energy produced by the nuclear fusion core will be converted into electrical energy by ferrofluid.

At that time, the remaining role of the PWR is mainly aimed at the heat generated by the deceleration of neutrons by the beryllium ceramic alloy on the first inner wall, as well as the heat released by the reaction between the neutrons and lithium in the rear lithium neutron recovery system, including the heat formed by the magnetofluid power generation system that has no time to convert.

The coolant takes away the heat generated by these systems and feeds it into the PWR circulation system, which drives the wheels to generate electricity.

When the ferrofluid power generation scheme is implemented, the energy output ratio of the entire reactor is 89 to 92 percent of the ferrofluid energy, and the rest is the pressurized water reactor. ”

As soon as Lu Yi's words came out, many people in the nuclear industry group present couldn't help but change their faces.

They are experts in boiling water for pressurized water reactors, heavy water reactors, and light water reactors, and if boiling water on nuclear fusion reactors becomes a marginal auxiliary role in the future, their treatment and future will suddenly be bleak.

"Chief Engineer Lu, will this plan you said too extreme, I know that in a nuclear fusion reactor, ferrofluid power generation will be more efficient than that of pressurized water reactors, but ferrofluid power generation is not without limitations."

An engineer gritted his teeth and said: "Helium in the plasma state of 100 million degrees Celsius is already terrifying, if the heat flow generated by fusion is channeled into the ferrofluid channel, this part of the heat flow will continue to heat the helium, including the magnetofluid channel, and the temperature will last for a long time."

I don't know exactly how your unfinished solution is going to solve this problem, but I guess there aren't many materials that can withstand such temperatures for long. ”

"The strength of the magnetic field increases, increasing the resistance to cutting the magnetic inductance lines, and finally the temperature of the inner wall material of the channel will be within the allowable value."

The biggest problem of ferrofluid power generation is not high temperature, don't look at the temperature of the helium and heat flow discharged by the deflector is terrifying, but its temperature is rapidly attenuated in the process of shuttle cutting magnetic inductance lines in the ferrofluid channel.

Through many modeling and analysis with Lin Meng, Lu Yi has determined that as long as the strength of the magnetic field at the poles of the ferrofluid power generation system reaches more than 76.3% of the current constrained magnetic field strength of tomorrow's stellar, then this temperature will not have time to act on the inner wall, most of it will be converted into electrical energy, and the remaining part of the heat energy will be within the tolerance range of the material even if it acts on the inner wall of the channel.

"Chief Engineer Lu, how to solve the electrode corrosion?" Another engineer who has some research on ferrofluids asks.

"I think you should have some understanding of the first inner wall scheme used by Max Planck Labs before."

Lu Yi ruthlessly pinched off this thought and said: "I asked about the situation in the domestic industry, we can't play this inside the stellarator, but it is no problem to process the electrode material into a similar movable structural layer on the magnetofluid power generation system. ”

In reality, the main problem that plagues the development of ferrofluid power generation technology is electrode corrosion.

When the heat energy is converted into electrical energy, the negatively charged electrons and the positively charged nuclei cause severe corrosion to the electrodes of the magnetofluid power generation system.

However, this problem, inspired by the previous ceramic sandwich scheme of Max Planck Laboratory, Lu Yi already had a solution in his heart.

"Chief Engineer Lu, I know the first inner wall scheme of Max Planck Lab before, but this solution is used in the ferrofluid system, and the operating cost is at least 1.5 billion yuan per day higher than that of the PWR solution......

An engineer said hurriedly after a quick calculation on scratch paper.

At this moment, they are no longer discussing learning, but trying to dispel Lu Yi's plan to save their future and job.

"I know what you're trying to say, but it doesn't make sense, the plan is already unchangeable."

Lu Yi shook his head regretfully, and said without giving a chance: "Through modeling and analysis, after adopting this ferrofluid power generation scheme, the energy utilization rate of the entire reactor can be increased by about 23 points, that is, the power generation efficiency can be increased by 23%.

I think it's clear to everyone what a fusion reactor with a power of up to 3,000 MW means by 23 percent more efficient.

Operating costs increase by 1.5 billion yuan per year, which is not worth mentioning at all, given the target of a 23% increase in total energy utilization.

This is an industry change, you can't stop it, and I can't stop it.

Rather than resist, you should accept it, I think you who have participated in the construction of the nuclear fusion demonstration reactor have a far better understanding of nuclear fusion than your peers.

Next, as long as you study the magnetohydroelectric power generation system carefully, it is impossible to become an expert in the field of ferrofluid power generation for the first batch of nuclear fusion reactors in China.

I will send you a rough plan that has been completed, and you can study it on your own, but don't think about the technology involved above, I have registered all patents......"
