"Chief Engineer Lu, after the inspection, you can carry out ignition!"

Reconfirming the situation of the demonstration reactor, an engineer came over and reported respectfully.

"Okay."

Lu Yi nodded, the shooting records of countless cameras around him, he walked smoothly to the front console, and gently placed his fingers on a red start button.

Under the watchful eye, Lu Yi quietly closed his eyes, was silent for two seconds, and finally pressed the button with his fingers that he didn't know whether to open the starting point of history or draw an end to history.

Whether it is heaven or hell ahead, no one knows, but no one can stop the wheel of the times as it rolls here.

Inside the core wrapped in the heavy pressurized water stack, at the moment when Lu Yi pressed the button, the pitch-black cabin was instantly lit up, and liquid helium flowed through the superconducting graphene coil, taking away the heat to lower the temperature below the superconducting temperature......

Hydrogen is injected, microwave heating parts heat the temperature to 100 million degrees Celsius, and the orange-red plasma ribbon is writhing beautifully.

After the core operation is confirmed by hydrogen, the deuterium and tritium elements are injected twice, and the power of the microwave heating parts is instantaneously increased to the temperature of the maximum stable plasma, and at a high temperature of 100 million degrees Celsius, the injected deuterium and tritium elements begin to polymerize, and the orange-red plasma ribbon instantly blooms with a strong light, and the most terrifying energy of this star system is born, it is very terrifying, but it is bound by the magnetic confinement magnetic field!

Fusion produced a large number of high-energy neutrons rushed out of the confined magnetic field, hitting the beryllium ceramic alloy on the first inner wall to slow down, the energy released by the neutron deceleration made the temperature of the inner wall rise crazy, but in the case of the internal cooling system constantly taking away the heat, the temperature rose to 2200 degrees Celsius and stabilized, only up and down slight fluctuations......

"The confinement magnetic field is stable, and the plasma is functioning normally!"

"The fusion reaction is normal, the deflector is working properly!"

"The temperature of the first inner wall is normal!"

"The neutron and lithium reaction is normal, the lithium neutron recovery system is normal, the tritium generated by the reaction has been detected, and the tritium recovery and re-injection into the plasma are normal!"

"No neutron radiation was detected on the periphery of the core, and the reactor is safe!"

"The temperature of the pressurized water reactor is increasing rapidly, the high-temperature and high-pressure steam is pushing the steam turbine set to rotate at high speed, and the generator set has detected the current! Report again, the genset has detected the current! ”

The large screen of the demonstration reactor control center is constantly refreshing the lines of operating data, and the reports of relevant engineers have been sounding, and the sound has been ringing, from apprehension, to calm, to excitement, until finally an irrepressible roar......

It worked! We did it!

The scene was boiling, and thunderous applause rang out on the live video broadcast in an instant, and the light from controlled nuclear fusion really shone on the world!

Lu Yi also had a smile on his face, happy for his results, and didn't want to show his emotions at this time to interfere with everyone's interest.

After everyone cheered and vented their excitement, Lu Yi clapped his palms to focus the attention of everyone present, and said with a smile: "Don't be busy cheering first, let's calculate the energy efficiency, don't make an unqualified demonstration pile."

"Yes." All the engineers present responded and continued to work with smiles on their faces.

Unlike thermal power stations, hydroelectric power stations or even fission reactors, nuclear fusion has its own energy expenditure because it needs to maintain the existence of a magnetic confinement magnetic field, and only if the energy output is greater than the energy expenditure, then it is a qualified nuclear fusion reactor.

However, everyone is not worried about this, based on the first-hand detection data, with experience, it is roughly estimated that the energy income is positive, and it is quite large.

"The energy efficiency is 41.6 percent, which is a bit low."

A few minutes later, Lu Yi got the energy efficiency of this demonstration reactor.

This data represents that only 41.6% of the energy produced by DT fusion is ultimately converted into electricity.

According to the boiling water technology of the experts of the nuclear industry group, the fission reactor can reach 50 percent after using high-temperature gas-cooled reactor and sodium fast cooling technology, and the difference between the front and back is 8.4 percent, which seriously exceeds the consumption of the confined magnetic field.

"Chief Engineer Lu, this is the first time to ignite power generation, and the various functional areas of the pressurized water reactor have not been optimized and adjusted."

Seeing Lu Yi's dissatisfaction, the boiling water expert of the Nuclear Industry Group hurriedly explained: "According to our calculations, the efficiency after the adjustment and optimization can reach 46 percent. ”

"I don't mean to blame, let's send this data to Shangjing." Lu Yi smiled and didn't blame anything.

"yes, then we're going to get busy." The engineer breathed a sigh of relief and turned to continue his busy work.

The demonstration reactor was successfully ignited and generated electricity, and not only the laboratory was busy, but also all departments and the Ministry of Information of the whole country were also prepared for the first time according to the predetermined plan, beware of the impact of economic fluctuations, and prepare relevant news bulletins.

These are all prepared in advance and have a special team in charge, and they do not need the help of Lu Yi and their group of core scientists.

"It's only 46 percent energy efficiency, which is too low."

Lu Yi and a group of people walked outside, Rupert looked back at the engineers who were busy collecting data, and couldn't help sighing.

If you don't realize the problem of thermal pollution, the energy conversion efficiency of 0.46 is okay, but after realizing the problem of thermal pollution, the conversion rate of 0.46 is very worrying.

This means that only 46 of the 100 parts of energy are converted into electricity, and the remaining 54 parts of the energy are released into the environment in the form of radiation, mechanical heat dissipation, and frictional loss of mechanical conduction.

Of course, the 46 parts of energy that become electric energy are not stable, they will be in the transmission of electrical energy, due to the problem of wire resistance, part of the heat will be released, after reaching the terminal of the electrical appliance, it will also be completely released into the environment with the heat dissipation and consumption of the electrical appliances.

According to the mathematical model, 93 to 95 percent of the energy produced by humans is emitted into the environment, and less than 7 percent of it will remain silent inside the substance without affecting the environment.

In any case, an increase in energy productivity means an increase in the proportion of available energy obtained, rather than being released into the environment as a hidden danger.

"In the next step, the efficiency of the mature ferrofluid power generation can reach nearly 70, which is very good."

Lu Yi shook his head and said, "So compared with the loss of energy conversion, we should focus more on the loss of energy transmission and the efficiency of energy consumption. ”

Although more than 93% of energy ends up in the environment, efficiency is also crucial in the process, which determines the amount of energy used and the degree of waste.

If the efficiency is doubled, then I can do two things with the same energy, and this gap is very strategic under the premise of the heat pollution crisis and the limited energy use.

"Wait, Lu Lu, what are you talking about mysteriously? What is the supercomputer being operating in a high-load state these days? ”

Zhang Qing, who was next to him, heard the conversation between Lu Yi and the two, looked at the quiet laboratory building, and seemed to realize something in his heart.

Lu Yi didn't answer Zhang Qing's question for the first time, and he suddenly found that the roar of supercomputing that he had been accustomed to in his ears in the past few days had quietly stopped.

"The problem of thermal contamination." Lu Yi said to Zhang Qing briefly, and then beckoned Rupert and said, "The results of the simulation analysis are out, let's go, let's go to the supercomputer room!" ”

"Thermal pollution? Earth cooling? What is the supercomputer simulating and analyzing in the past few days is the model of the earth's environment? ”

Zhang Qing, who was studying the space gravitational wave project, was stunned when it came to the space station, and the next moment he realized the seriousness of the problem, and hurriedly chased after Lu Yi with Lin Meng and Li Yashan.

"Old Wei, what's going on?"

Hu Feng, who was studying the materials, saw that his face became so ugly one by one, and asked Wei Hong, who was also stunned, who was also stunned, who was a little puzzled.

During this time, Wei Hong's research on space engines involved a lot of material problems, and he looked for Hu Feng, and the two of them were already very familiar.

"A terrible, terrible thing."

Wei Hong's mind came up with the problems caused by the difficulty of heat dissipation in the space station, and he took a deep breath and shook his head: "We also went over, I hope it is not what I thought." ”
