187: Chapter 187 Revolutionary Materials, Nobel Prize!
Professor Qian Wenwen asked: "Engineer Xu, should we proceed with reinforcing the protective device layer by layer based on the calculation results until the calculated safety threshold is reached?"
After he finished asking, Professor Du Zhongshu and the many researchers in the Research Institute all looked at Xu Hao.
The ultimate goal, after all, was to achieve shielding against nuclear ships for the human body and biological organisms.
Since Engineer Xu had already provided the calculation method for biological shielding.
Did it mean that one could calculate the biological shielding value using this method and then stack protective devices to achieve the shielding effect?
Hearing Professor Qian Wenwen's question, Xu Hao smiled and shook his head.
"Elder Qian's line of thinking is not wrong, but there is no need to use conventional means to achieve the shielding effect."
After saying this, the researchers present were suddenly filled with confusion.
What did Engineer Xu mean by this?
Xu Hao continued to explain:
"First, we must understand the requirements and characteristics of biological shielding for a Nuclear-powered Aircraft Carrier."
"Ensure that the annual external radiation dose received by ship personnel meets the limits specified in the ship's radiation shielding design criteria."
"Ensure that the radiation dose for personnel performing tasks in compartments adjacent to the reactor compartment does not exceed the permissible dose level."
"Allow within a limited time..."
Xu Hao spoke in detail about the design requirements for ship biological shielding, and the researchers nodded one after another.
"Once we know these design requirements and have obtained the biological shielding values, we must consider the materials for biological shielding."
When Xu Hao said this, everyone perked up, their expressions sharpening.
"We know that nuclear radiation shielding mainly considers the shielding of neutrons and Ξ³-rays. Generally speaking, materials that have good attenuation performance for Ξ³-rays will also produce secondary Ξ³-rays due to neutron inelastic scattering and radiative capture."
"This shows that the generation of secondary radiation is also a factor that should be considered."
"Therefore, this requires our anti-radiation protective devices to have many characteristics, such as high density, high hydrogen content, low energy of capture Ξ³-rays released during neutron absorption or moderation, and a certain degree of mechanical strength."
As Xu Hao analyzed deeper, the expressions of Professor Qian Wenwen and Professor Du Zhongshu became increasingly solemn.
If all the above characteristics were to be possessed simultaneously, it seemed that no material manufactured with current technological levels could satisfy them.
Otherwise, nuclear radiation shielding would not still rely on protective measures like several meters of thick concrete.
For a Nuclear-powered Aircraft Carrier, this was a heavy burden.
"Engineer Xu, how should we solve this then?"
Professor Qian Wenwen asked.
Xu Hao capped his pen, placed it back on the desk, and a confident smile appeared on his handsome face.
"New material!"
He said calmly and firmly.
"New material?"
Professor Qian Wenwen was stunned.
What kind of new material could meet these requirements?
Professor Du Zhongshu also looked puzzled.
As far as he knew, neither domestically nor internationally was there such a material that could meet these requirements.
"Engineer Xu, what kind of new material is it?"
Professor Du Zhongshu asked.
Xu Hao opened the folder and pulled out a document from inside.
"Professor Qian, Elder Du, please take a look. This is the new material for the nuclear radiation protective device!"
Xu Hao handed the two handwritten documents to the two elders.
Out of curiosity, they took them from Xu Hao's hand and carefully read the information above.
As the two professors read on, it was evident that their calm eyes were faintly flickering with light.
After a long while, Professor Qian Wenwen said with a trembling voice:
"New material... it is actually a new material for nuclear radiation protective devices!!"
His hands trembled slightly, and his tone was filled with irrepressible excitement and shock.
Professor Qian Wenwen had never expected that Xu Hao would actually produce a formula for a new material for nuclear radiation protective devices.
According to the ratios above, if this formula was true, the produced new material could achieve complete absorption of Ξ³-rays and neutrons.
Truly achieving zero nuclear radiation.
Shocking!!
Professor Du Zhongshu's expression was no less than Professor Qian Wenwen's.
He was a professor at the Research Institute and understood the importance of this formula even more clearly.
It was no exaggeration to say.
If this formula sheet were to leak out, the materials science and physics circles would be shaken by it.
It would completely break the understanding of nuclear radiation protection.
Human protection against nuclear radiation would step into a brand-new stage.
He stood up unsteadily.
"Engineer Xu, was this formula for the new material developed by you?"
Professor Du Zhongshu asked nervously.
Xu Hao smiled without saying a word and nodded.
Boom!!
Professor Du Zhongshu was shocked and took two steps back, and the researchers behind him hurriedly supported him.
Likewise.
Countless researchers in the laboratory were now looking at Xu Hao with burning gazes, their faces full of disbelief.
Engineer Xu had actually developed a new material for nuclear radiation protection.
Such explosive news struck their minds like a thunderbolt, leaving them dizzy.
It was too incredible!
While they were all thinking about how to cleverly design to reduce the impact of nuclear radiation.
Engineer Xu directly brought out a brand-new material formula.
"Huu..."
Many people took a deep breath, digesting this news that would set off a massive change in world nuclear protection.
After a long while, Professor Du Zhongshu slowly calmed his excited mood.
He looked at Xu Hao and exclaimed:
"Engineer Xu, this is a new breakthrough and discovery in physics and materials science. The future achievements will be absolutely huge, even unimaginable."
"It will overturn the understanding of the entire nuclear engineering field."
"Engineer Xu, I suggest that you publish several international papers on this new material."
"Counting the time, it is June now, and it will be just in time for the Nobel Prize selection starting in September!"
"There is a very high possibility of winning the Nobel Prize in Physics!!"
Professor Du Zhongshu said in an excited tone.
The researchers in the audience were equally excited when they heard Professor Du Zhongshu's words.
The Nobel Prize, this is a supreme international award!
Is Engineer Xu going to win this award?
Everyone felt incomparably excited!!
Xu Hao thought for a while after hearing Professor Du Zhongshu's words.
Nobel Prize...
To be honest, he was not very interested.
But at the same time, Xu Hao wanted to verify whether the progress bar would increase if he won such an international award?
Since that was the case, he intended to write a few papers on this new material and publish them in international journals.
The Nobel Prize selection was relatively fair.
He believed that if such a paper were published, winning the Nobel Prize would be relatively easy.
"Thank you for your guidance, Elder Du. I will write a few papers later and publish them in international journals."
Hearing this, Professor Qian Wenwen and Professor Du Zhongshu both breathed a sigh of relief, with smiles on their faces.
Xu Hao added:
"I have been doing theoretical research for the past few days and have not conducted experiments. I trouble Professor Qian and Elder Du to let the experimental personnel test according to this formula to see if it can pass the inspection."
Xu Hao requested.
"Understood!" Professor Qian Wenwen nodded and agreed.
Then he immediately handed this formula sheet to the professional experimental personnel and let them conduct experiments.
At this moment, Zhu Deze finally had the opportunity to step forward.
