At the scene.
Under the director's request, Sa Benin took a long time to react. Under the questioning gaze, he coughed and walked forward to pick up the A4 paper that Li Feng had thrown on the ground. He waved it at the camera and asked,"Student Li Feng, can you introduce to everyone what's on this piece of paper?”
Li Feng didn't feel anything about Sa Benin's question. He said casually,"It's all a formula. Can't you tell?”
"This…I don't understand either.”Benin wiped the cold sweat from his forehead. He was just a host at best. How could he understand these complicated scientific formulas? He thought for a moment and smiled at the judges. There was an old professor sitting there with his eyes closed. He looked to be in his seventies or eighties. He was a nuclear energy professor that the program team had specially hired from the National Academy of Sciences. He was well-known both domestically and internationally.
Benin looked at him and said," But this is a small problem. In order to ensure absolute fairness, our program team specially invited the famous nuclear energy professor from the National Academy of Sciences, Jiang Haize! "Come, Professor Jiang. I think you're knowledgeable. You'll definitely be able to understand what our Student Li Feng wrote.”
The audience immediately focused their attention on the old man.
Professor Jiang opened his turbid eyes. He didn't look at what was written on the paper. Instead, he looked at Li Feng and sized him up. He waved at him and said,"Child, come to Grandpa."
When this scene appeared, everyone fell silent.
The camera was also aimed at Li Feng, who was smoking.
Everyone wanted to see what this rude high school student would do.
Li Feng smiled and walked toward Professor Jiang shyly.
He was quite respectful towards an old man who had spent his entire life researching science.
Professor Jiang patted Li Feng's shoulder and asked him to sit beside him. He asked,"Li Feng, do you know what Grandpa does for a living?”
"Professor of nuclear energy, one of the top ten academicians in the country.”Li Feng shrugged his shoulders and said," If you have any questions, just ask them directly.”
"Good, good, good. You're indeed a talent of the future.”Professor Fang narrowed his eyes and smiled. In front of everyone, he asked softly," Let me ask you, do you know what nuclear energy is? What is a fission chain reaction?"
Almost all the audience, whether they were at the scene or in front of the TV, looked at Li Feng with ridicule.
If he couldn't even answer what nuclear energy was, this child would probably be sprayed until his skin was completely mutilated.
But what they didn't know was-
In Li Feng's mind, this kind of question was no different from "how to cook rice."
" Nuclear energy, or atomic energy," he said softly." It is the energy released from the nucleus through a nuclear reaction. It conforms to Albert Einstein's mass-energy equation, E= mc2, where E= energy, m= mass, and c= light speed. Nuclear energy can be released through one of three types of nuclear reactions. The first type is nuclear fission, where the heavier atomic nuclei split to release nuclear energy. The second type was nuclear fusion. Lighter atomic nuclei were gathered together to release the energy of the nuclei. The third type was nuclear decay, which released energy during the spontaneous decay of the atomic nucleus.”
He paused." What is a fission chain reaction? There were two main ways to obtain nuclear energy: heavy nuclear fission and light nuclear fusion. It had a characteristic that when a neutron bombarded its nucleus, it could split into two smaller nuclei, producing two to three neutrons and beta, gamma-rays, and releasing about 200 megaelectron volts of energy. If a newly produced neutron bombarded another Uranium-235 nucleus, it would cause new fission, and so on, so that the fission reaction would continue. This was the fission chain reaction, in which nuclear energy was continuously released.”
The moment he said that, the audience was dumbfounded.
What mass-energy equation?
Nuclear fission?
What fission chain reaction?
Other than a few professors, almost no one understood what he meant!
Everyone looked at Li Feng in disbelief.
This guy…
Was he really only sixteen years old?
How could he know so much at such a young age?
Or was it…
This kid is memorizing?
Professor Jiang coughed a few times, but he was still a veteran scholar. He nodded and asked calmly,""Then, do you know what nuclear waste is?”
Li Feng shrugged and nodded." In these three nuclear reactions, highly radioactive nuclear waste will be produced. It contains nuclear radiation, which can cause great harm to the human body. My invention can easily collect these nuclear waste and then vaporize them in the accelerator driven subcritical system. The high-energy and high-current neutron beam produced by it will bombard the heavy nucleus to produce a wide energy spectrum. High-flux spalling neutrons will be used as an external source to drive the fission material in the subcritical core to undergo a chain reaction.
"After the fission reaction occurs, it will produce fission products with a shorter half-life and less toxicity. In layman's terms, it was to create an incinerator for high-level radioactive and long-lived nuclear waste. It would convert high-level radioactive and long-lived natures into medium-short-lived, low-level or stable natures. At the same time, energy would be released during this process. This energy could be used to generate electricity, which was equivalent to turning nuclear waste into nuclear fuel that could be used for power generation, turning waste into treasure.”
The last word fell.
The entire place fell into a deathly silence.
This…
He couldn't understand it anymore!
Other than Professor Jiang, the other five judges were already wiping the sweat off their foreheads.
It had to be said that this sixteen-year-old high school student had indeed exceeded their expectations.
But in the end, these were all just words.
Who doesn't know how to memorize textbooks?
Professor Jiang smiled faintly." Not bad. Your theoretical level has already surpassed all the competitors of the same level. You even know about the experiments that only exist in theory, such as the wide-energy spectrum produced by the bombardment of heavy nuclei by high-energy high-current photon beams. I wonder which famous physics teacher in China taught you that?”
"Teach? Do you still need to teach me?" Li Feng smiled faintly and said," I learned it myself.”
"Self-study? How is this possible?" Professor Jiang shook his head and sighed." Li Feng, do you know how difficult it is to drive the fission material in the subcritical core to undergo a chain reaction? The amount of energy needed to do this was not something that could be settled with a few words! Do you think memorizing a few professional terms will be useful? So far, nuclear waste could only be buried on the spot or closed cycle. There was no way to guarantee that it would completely lose its radiation. No scientist in the country or even the world dared to make such a big fuss!”
