Chapter 255 This is already very strong!
In the observation room, on the screen that records the current output information, a series of numbers are constantly beating.
Witnessing the arrival of this scene, everyone in the observation room had an expression of excitement on their faces, and all the researchers clenched their fists in excitement because of the scene in front of them.
Reusing nuclear waste to generate electricity sounds like a fantasy, but they actually did it.
Standing behind Academician Peng Hongxi, Xu Chuan also had a smile on his face as he watched the values beating on the screen.
Although this was a technique he had already developed in his previous life, in a different environment, the meaning was completely different.
When the problem of nuclear waste is solved, nuclear power plants will be active in every piece of land in the motherland.
Although the energy problems can not be completely solved, they can also be alleviated to a considerable extent.
After all, uranium resources are quite abundant on the earth, and the average uranium content in the earth's crust is almost 2.5%.
The total amount of conventional and unconventional uranium resources in the world is enough for human use for hundreds of thousands of years, not to mention that there are still large amounts of uranium resources in seawater.
If all the uranium in seawater around the world were extracted, the total amount would exceed four billion tons.
If such abundant uranium resources can be fully utilized, the energy problem will be completely solved.
Of course, it's a long way to go.
The value on the screen jumped with time, and finally stabilized in a range.
5.3C, which is a unit used in the laboratory to measure power generation.
If we convert this, the radiation power conversion equipment representing the ongoing experiment can provide approximately 0.7 kilowatt hours of electricity per hour.
That number doesn't sound like much, but it's pretty good.
If calculated according to this standard, a nuclear waste power station covering an area of 2,000 acres and using 500 tons of nuclear waste can provide almost 2 billion kilowatt hours of electricity every year.
Although this number cannot be compared with conventional nuclear power plants, it is equivalent to a thermal power plant with an installed capacity of about 1 million kilowatts.
A one-million-kilowatt thermal power plant is considered a medium-to-large thermal power plant in China.
Based on Jinling's annual electricity consumption of 40 billion kWh last year, twenty such power stations can provide the corresponding amount of electricity.
But currently, China does not have that much nuclear waste.
At the end of 2018, according to the detailed data provided above, China's current high-level radioactive nuclear waste was less than 1,000 tons.
This number can only be used by two nuclear waste power stations.
But compared with ordinary nuclear power plants, these two nuclear waste power plants have a huge advantage.
That is, its fuel has a long service life, and the nuclear waste inside has a service life several times or even ten times longer than ordinary nuclear fuel rods.
The service life of nuclear fuel rods in ordinary nuclear power plants is generally about four to five years, while the radioactive decay of nuclear waste can last for hundreds of thousands of years.
Of course, its actual power generation time cannot be maintained stably for that long.
After all, as time goes by, the radioactive intensity of nuclear waste will also decrease.
This results in reduced power generation.
But it is not impossible to solve it. Special means can be used to stimulate and improve it. Using an accelerator to drop high-speed particles to hit nuclear waste can accelerate the radioactive decay of nuclear waste and maintain the scale of power generation. Theoretically, after a power station using 500 tons of nuclear waste is constructed, it can be maintained for approximately fifty to sixty years.
During this period, the power generation output can be stably maintained, providing approximately 100 billion kilowatt hours of electricity.
Calculated based on the current calculation that one ton of ordinary nuclear fuel rods can emit about 330 million kilowatt-hours of electrical energy, this number is almost two-thirds of that of 500-ton nuclear fuel rods.
It sounds incredible that nuclear waste can provide electricity comparable to nuclear fuel.
But in fact, what it can really do, the energy that atomic fission can provide is quite terrifying.
It's just that at present, humans simply cannot make perfect use of it.
At present, the utilization rate of nuclear energy by science and technology is less than 1%. When the day comes, energy will no longer be an obstacle to the development of civilization.
In the observation room, Academician Peng Hongxi stood in front of the display screen for a long time, his face flushed, his hands clenched tightly, and his lips trembling slightly.
After a long time, he turned around, looked at the young man standing behind him with complicated and reddish eyes, and asked nervously and expectantly:
"Is this a success?"
Although the numerical value in front of him verified his thoughts, he needed this person's affirmation even more at the moment.
He hoped to see the other party nodding, but was afraid that the other party would shake his head and dash his dream.
But fortunately, the young man standing behind him nodded gently with a bright smile: "If there are no accidents, we succeeded."
After receiving an affirmative answer, the old man immediately felt relieved, with a smile on his face, and said with emotion: "A century-long problem has come to a successful end in your hands. If you hadn't seen it with your own eyes, I can’t believe this is true.”
"Reusing nuclear waste sounds like a dream, but now it has come out of the dream. It not only solves the most troublesome pollution problem, but also turns it into energy."< br>
Xu Chuan smiled and said: "Isn't this science and the meaning of the existence of people like us?"
Hearing this, Peng Hongxi was stunned for a moment, then smiled and said: "Yes, but there are not many people who can really do this from ancient times to the present."
Xu Chuan smiled, looked at the display screen, and landed on the numbers that were still beating, and continued: "Actually, this technology is not perfect at present."
Hearing this, Peng Hongxi's heart tightened and he quickly asked: "What should I say?"
Xu Chuan said: "Theoretically, this technology cannot utilize all the radiation energy emitted by nuclear waste."
"Whether it is alpha rays with extremely weak penetrating power, or neutron flow with extremely strong penetrating power that basically does not interact with materials, it is basically impossible to use it. The former is blocked outside the semiconductor from the beginning, while the latter mainly Rely on the protective materials outside to resist. ”
"This technology mainly collects part of beta rays and gamma rays. It uses the electron pair effect and photoelectric effect of these two rays to generate energy."
"It will also cause most of the radiant energy to actually overflow and be wasted."
"If we can go further."
Hearing this, Peng Hongxi was stunned again, and then interrupted him with a smile: "Hey, you said that!"
"I thought there was some major flaw in the design, but I didn't expect this is what you were talking about."
After a pause, he continued: "If this can be considered a flaw, then there is nothing perfect in the world."
"This is already very strong!"
PS: I was busy today and wasted time. I only wrote more than 2,000 words. I will add another chapter tomorrow.
