Chapter 1383 Faraday's Grip
"That core transformation plan..."
After a while, Peng Juexian asked with some concern.
He only assisted in the closed-loop nuclear magnetic fluid power generation project and was not responsible for any specific R&D work, so he was not particularly worried about the speed of this part of the timetable.
But the renovation progress of the 504 factory is strongly bound to the isotope production base he is young to amaze. If this affects the latter's construction, it will be a huge loss.
"Don't worry... If nothing unexpected happens, the progress of the pile-up can still be carried out according to the original plan."
Chang Haonan of course knew what the other party was most concerned about.
However, before the other party could breathe a sigh of relief, he changed his mind:
"But there is something you have to do me a favor."
Peng Juexian instinctively felt that This may not be simple.
But now that things have come to this point, he can't refuse:
"You said."
Chang Haonan was straight to the point:
"I need the reactor to operate at full power for a period of time."
The two of them said it very clearly before.
All other tasks can be decided by Chang Haonan alone, but the operations related to the core need to be approved by Peng Juexian.
After saying that, before waiting for the other party to answer, he suddenly turned around and glanced at everyone present: "Old Han, during the period when the core is running at full power, you have brought people to the heavy weight. Do a power supply design analysis of the coil, and measure the magnetic footprint strike point distribution of the yoke frame..."
Seeing that Peng Jue wanted to speak first but stopped, he raised his hand and explained: > "Realistically speaking, the increase in magnetic induction intensity alone should not lead to such obvious electromagnetic induction interference... So, I suspect that the root cause is related to the operation of the nuclear reactor itself."
The former narrowed his eyes slightly, and although his face still had an unquestionable expression, he immediately turned his head and found several technicians.
The radioactivity of the second circuit is indeed very low, but that is for humans.
Now a large amount of ionizing seeds have been added to the steam pipeline, and no one can guarantee that there will be no effect at all. "Rise the control rod to the maximum allowable value below the critical state." He ordered.
Chang Haonan added next to it: "Do it divides into several stages, don't improve it to the maximum at once..."
...
As more and more The control rod is raised, and the neutron flux inside the core increases, and the chain reaction rate also accelerates to the highest level within the rated range in the following dozens of minutes.
In front of the console, several operating engineers closely monitored the distribution of particles and magnetic fields in the second circuit and disc generators.
Han Chenfeng was a little idle at this moment, and was upset and couldn't sit still.
After walking back and forth a few times, I simply picked up the toolbox: "I'll go and check the working conditions of the coil on the spot."
So, this action seemed to be open. What switch is the same.
I saw that the second-loop radiation warning light, which should have been green, was flashing orange at a frequency of three times per minute.
Peng Juexian was shocked and almost subconsciously made a judgment: "Hey, is the pipe leaking in the first round?"
But his heart was full of confusion.
The thermal power of the small test reactor is very low, and the safety margin of each system is rich to an exaggerated level. Logically speaking, such an outrageous problem is impossible.
He strode to the main console and recalled radiation monitoring data, and was ready to let someone out all unrelated personnel such as Chang Haonan.
But I found that all indicators were within the safe range.
This contradiction made everyone present stand up -
Unknown problems are often more deadly than the danger of open fire.
"Don't worry, give me some time." Chang Haonan's voice was extremely calm:
"The second circuit itself will not produce new neutrons, and our radiation value is also There is no change, which means it is not a leak...at least it is not a direct leakage of steam from one circuit."
He called out a three-dimensional model of the magnetic fluid channel and superimposed the radiation data and the magnetic field disturbance map:
"Look here-ever the neutron flux suddenly increases, it will be accompanied by the magnetic field position shape. Spinning about three-tenths."
Han Chenfeng was still holding the tool box in his hand, but he slapped his forehead suddenly:
"The fast neutron bombardment of ionizing seeds is produced Transient plasma? ”
Peng Juexin also calmed down again and returned to the computer to retrieve the original data: "In other words, even a traditional reactor that uses water as a cooling medium will be stimulated to produce a part of the plasma?"
"So the real culprit is."
"Coupling resonance between nuclear fission and magnetofluid power generation."
Chang Haonan wrote a series of formulas on the whiteboard:
"Even if the protection is good, it is impossible to prevent the periodic penetration of trace fission products into the second circuit... These high-energy particles not only interfere with the stability of the ionized seeds, but also amplify the distortion amplitude of the magnetic surface structure through their interaction with the disturbing magnetic field."< br>
The control room fell into silence, and only the buzzing of the cooling fan shook in the air.

In the end, Han Chenfeng broke the deadlock first:
"So the solution is "
"Two-pronged approach."
Chang Haonan drew two overlapping circles next to the formula:
"Although as long as a chain reaction is involved, the interference source of neutron radiation cannot be completely eliminated, But it can increase the shielding efficiency."
Peng Juexian frowned:
"Boron carbide or boron-containing polyethylene coating...but your nuclear battery has no second circuit. Can't be shielded on the surface of the core fuel rod? "
"No, use liquid lithium."
A sharp light flashed in Chang Haonan's eyes:
"Or to be precise, add a part of the lithium-6 isotope."
>Peng Juexian slapped his thigh suddenly:
"Although the neutron capture section of lithium-6 is small, it is in the fast neutron flow..."
He suddenly stopped and turned to look at Chang Haonan: "Do you still want to use this process to strengthen ionization?" Chang Haonan nodded: "Lithium-6 Tritium will be generated during the activation of neutrons, which is just used as a supplement to plasma. The released α particles are also extremely strong ionization sources within a short distance, so there is no need to worry about penetration..."
Alpha particles have strong ionization ability but weak penetration. It is generally believed that only one piece of paper is needed to block it and cannot penetrate the reactor shell at all.
"In fact, Americans did similar experiments in the 1990s, but at that time." "It was only later that their magnetofluid power generation project was discontinued." Han Chenfeng replied, With excitement in his tone:
"I'll contact the institute now and prepare to prepare relevant raw materials..."
Chang Haonan held him down:
"Don't worry about this, it's not too late to prepare after the renovation project starts..."
After saying that, he walked back to the edge of the whiteboard: pointing to another circle and said:
"And in the final analysis, he went to the edge of the whiteboard again: , we still have to find a way to suppress basic magnetic disturbances."
Han Chenfeng looked at the real-time monitoring data and suddenly sighed:
"So in the end, we have to go from a theoretical level."
"But there will be a large number of new data this time."
Chang Haonan pointed to the console where the alarm gradually weakened:
"If it succeeds, we will have a hand …”
“A Faraday’s hand that can weave magnetic wires.”
