Chapter 424 Shining Like a Star!

Standing in front of the main console, looking at the buttons in front of him, Xu Chuan took a deep breath again and spoke with a slightly trembling voice.

"Everyone, I am honored to stand here with you today and witness the miracle of history."

"No matter what the future holds, no matter today's results, we will go down in history!"

The two short sentences, with a little trembling, made everyone hold their breath involuntarily, and their eyes focused on the figure in front of the main console.

Xu Chuan did not hesitate anymore and pressed the button hard.

The CTV media reporter who was always paying attention to the movements here quickly pressed the shutter and captured this historic moment.

With the activation of the ICRF heating antenna, the temperature inside the Dawn Demonstration Reactor chamber continued to rise.

The deuterium and tritium raw materials that had already been put in quickly completed the transformation into plasma, and were then restrained in the dark chamber by the magnetic field provided by the external field coil.

As the temperature continued to rise, a glimmer of light gradually appeared in the dark reactor chamber, just like the early universe.

The quiet blue shines in the chamber, as beautiful as the Milky Way, and like the Milky Way, it breeds stars.

A short time passed, and as the ICRF heating antenna continued to heat up, the final moment finally arrived.

At this moment, the light shining like a star and the energy as majestic as a sea of ​​stars were released from the fused atoms, brilliant as light, lighting up the entire universe like a supernova.

In the main control room, Xu Chuan gritted his teeth, clenched his fists, and stared at the screen on the main console.

There were no instructions, no cheers, everyone sat at their posts and continued working according to the rules that had been arranged.

The biggest difference between the test reactor and the experimental reactor is that the demonstration reactor is a complete set of projects.

From controlling the high-temperature plasma turbulence in the reactor chamber to the occurrence of fusion, neutron irradiation to complete tritium self-sustainment, and then guiding the heat in the chamber to complete power generation, all processes of controllable nuclear fusion technology can be found on the demonstration reactor .

Now that they have completed the ignition, the next step is to control this star-like energy.

In the main control room, everyone is working at their posts.

The CTV media reporter took advantage of the opportunity to take some additional photos, and then quickly retreated to a corner to avoid disturbing the work of others.

Standing in front of the main console, Xu Chuan waited silently.

[The current external field coil is in good condition and the steady-state magnetic field output intensity is stable! 】

[Deuterium-tritium fusion reaction detected! 】

[Neutron irradiation detected on the first wall! The first wall is currently in stable condition! 】

[The Helium III observation system is operating normally, and it is observed that the plasma in the chamber is operating stably! 】

[The liquid lithium molten salt multiplication tritium system is operating normally and tritium production is detected! 】

【.】

Reports one after another sounded in the main control room one after another. Each voice was filled with excitement and trembling, but it pushed the atmosphere in the main control room to its peak step by step.

Standing in front of the main console, Xu Chuan didn't know how long he had been waiting.

Finally, a trembling voice made his eyes brighten quickly.

[The tritium recovery system is operating well, and tritium has been recovered from the liquid lithium molten salt multiplication tritium system! 】

The first ignition, that's the ultimate goal.

The recovery of tritium means that a complete cycle other than power generation has been completed.

Although it is still under experiment and it is impossible to judge the efficiency of neutron utilization and tritium self-sustainment and recovery efficiency, the goal of the first ignition has been achieved.

Tritium is self-sustaining, which is one of the most important cores in controllable nuclear fusion technology.

Only by achieving this can the Daybreak Demonstration Reactor be continuously operated for a long time.

After all, it is simply impossible to rely on the outside world to provide tritium like deuterium.

Only when the problem of tritium self-sustainment is solved can controllable nuclear fusion be realized.

Otherwise, even if it achieves ignition, power generation, and output, it will not be able to support its long-term operation.

The first ignition operation does not take very long.

Taking the tritium recovery system as a standard, twenty minutes is enough for the tritium recovery system to obtain enough data, and it is also enough to judge the core points of neutron utilization efficiency, tritium recovery value and other aspects through this batch of data. .

After the time reached this limit, Xu Chuan decisively clicked the command.

"All units and teams should pay attention and stop the operation of the Dawn Demonstration Reactor."

"receive!"

"receive!"

"."

As the input of deuterium and tritium raw materials stopped, and as the ICRF antenna stopped heating, the temperature in the Dawn Demonstration Reactor chamber began to decrease rapidly and steadily.

The excess heat is quickly discharged along with the water-cooled divertor, and the plasma involved in the reactor chamber also quickly changes back to normal, and is then discharged through the helium ash port.

From now on, the Dawn Demonstration Reactor will cease operations for thirty minutes.

During this period, engineers will conduct a preliminary inspection of the overall condition of the demonstration reactor and related equipment to determine the status of the demonstration reactor after the first ignition.

At the same time, researchers from the tritium recovery system group will use supercomputers to quickly sort and calculate tritium recovery data to determine whether the TBR value of the fusion reactor cladding meets the standards.

If all goes well, the Dawn Demonstration Reactor will restart in half an hour.

The second ignition will achieve the second goal of the day, and will also be the last goal, to connect to the generator set and complete the large cycle power generation!

The Dawn Demonstration Reactor was shut down, but the staff of each unit and group remained at their work stations.

Thirty minutes would not be considered long in the past.

But today, when every second counts, it seems like a whole century has passed.

Finally, the overall test results of the Dawn Demonstration Reactor came out first.

A document with residual heat was quickly sent over by Zhao Hongzhi.

With excitement and excitement, he reported the results to Xu Chuan with a trembling voice: "Report, the interruption inspection of the Dawn Demonstration Reactor has been completed, and the current demonstration reactor and various supporting equipment are in good condition! There is no obvious damage to the first wall material and structural material, and the ignition experiment can continue!"

Xu Chuan nodded, took the report file and read it carefully.

The demonstration reactor is in good condition, and there is no obvious radiation damage to the first wall material and structural material. This is expected.

However, the news from today's ignition experiment still makes people feel happy.

After waiting for a while, the data of the tritium recovery system finally came out with the cooperation of many scientific researchers and the Dawn supercomputer.

Academician Duan Jianming, who was in charge of this aspect, took the data verified by the supercomputer as soon as possible.

[Fusion reactor blanket TBR numerical statistics: MCNP: 1.3398]

[Fusion reactor blanket TBR numerical statistics: MCNP: 1.3406]

Seeing these two data, Xu Chuan finally smiled.

The average TBR value of the fusion reactor blanket is above 1.3! It is nearly 0.05 points higher than the tritium self-sustaining tritium recovery experiment done by the Dawn experimental reactor before. The result is perfect.

Taking a deep breath, Xu Chuan stood up and issued a new order again.

"Attention, all units and groups, the second round of demonstration reactor ignition work has begun!"

Along with the transmission of the order, the steel behemoth lying quietly in the core area once again roared its own roar.

The repeated journey was quite steady, and all indicators quickly returned to the standard state.

Looking at the data and images on the main control screen, Xu Chuan calmly issued a new order.

"Generators, please pay attention. The system will be connected in one minute. Please be prepared!"

From the operating data of the Dawn Demonstration Reactor, everything is perfect.

Now, it's time to turn on the last switch and release its endless energy!

The clear voice was transmitted to the ears of the generator crew through the headset. Standing in the control room on the other side of the demonstration reactor engineering base, Academicians Wang Yongnian and Hou Chengping looked at each other and nodded to each other.

It's their turn!

Although they were unable to stand in the main control room to witness history, they also shouldered the most important mission.

All preparations have been made, just waiting for the last moment.

One minute is not long. When the countdown ended, the staff sitting in front of the computer pressed the finger that had been hovering on the button.

The heat energy flows to the generator set through guidance.

Controlled nuclear fusion power generation and conventional nuclear fission power generation, apart from the magnetohydrodynamic generator set, are actually not much different in the power generation process.

Both of them guide the heat generated by nuclear energy to the generator set, and then provide heat to the steam generator, heat the liquid water into steam, and then drive the steam turbine to rotate, converting thermal energy into mechanical energy; then the steam turbine drives the generator to rotate, converting mechanical energy into electrical energy.

As for the magnetohydrodynamic generator set, that is another principle.

Of course, there is a difference between nuclear fusion power generation and nuclear fission power generation.

For example, in terms of controlling power generation, nuclear fission controls the nuclear reaction rate in the nuclear reactor by cutting off the control rods, absorbing neutrons, thereby slowing down the nuclear reaction rate and reducing heat output.

Nuclear fusion, on the other hand, is to input as much deuterium and tritium raw materials into the reactor chamber as you need electricity and heat energy.

As long as the upper limit of the reactor chamber is not reached, as long as you have enough generator sets, then a controlled nuclear fusion device can drive a considerable number of generator sets.

With the access of a group of magnetohydrodynamic generator sets + conventional units, a new round of experiments has begun.

When the energy comparable to that of a star was guided out of the Dawn Demonstration Reactor, the generator set deployed not far away started to operate smoothly!

The fuel heated into plasma quickly flowed along the pipeline to the magnetohydrodynamic generator set, cutting the magnetic flux lines at high speed, and then converted into a steady stream of electrical energy.

And this is not the end. The plasma that has experienced a round of power generation still contains considerable energy. They will follow the guidance and flow to the ultra-supercritical generator set and supercritical generator set, continuing their mission and dedicating every bit of heat.

In the main control room, Xu Chuan stared at the screen closely, waiting for good news.

Finally, a loud report sounded in everyone's ears.

[The No. 1 magnetohydrodynamic generator set is working normally! High-temperature plasma cutting magnetic flux lines is detected! Power output is detected! ]

[The No. 1 ultra-supercritical generator set is working normally! The current steam generator temperature has reached the critical value! The steam turbine has started! Power output is detected! ]

[The No. 1 supercritical generator set is working normally! The current steam generator temperature has reached the critical value! The steam turbine has started! Power output detected! 】

[The load of the No. 1 combined generator set has reached full load, and the current total power generation has reached the peak! ]
