Chapter 1380 Isotope Production Reactor
On the hillside in the western suburbs of Jincheng, the blue colored steel tile roof of the Nuclear Industry 504 Factory workshop looms in the twilight.
Peng Juexian pushed his glasses, looked at the barbed wire and warning signs passing outside the car window, and suddenly spoke:
"Fifteen years ago, when I first came here, the guard camp here was the first time I came fifteen years ago Even the automatic rifle was not equipped, and it was still used for five or a half. "
Han Chenfeng, who was reading notes next to him, looked up when he heard this.
Through the side window glass, you can see the 81-1 assault rifle on the chest of the soldiers in the guard booth with a dark blue reflection.
He curled his lips, thinking that he didn't seem to keep up with the pace of the times now. After all, even the local military districts in Shengjing have begun to change into newer models of assault rifles.
Han Chenfeng does not know light weapons, but the magazine of the new gun is located behind the grip, and even a pure layman can recognize the difference at a glance.
But before the opening was heard, a lieutenant colonel in charge of picking up the car in the passenger seat seemed to have guessed his thoughts and explained in advance:
"Actually, he has already changed to 95 long ago However, the main function of the whistle at the door is deterrence and warning. After using it, I found that the new gun was too short and the plastic feel was too heavy. Moreover, when I was holding the gun, the magazine was blocked by my arms and could not be seen from the front... In short, the deterrence was insufficient, resulting in the sentry The frequency of passwords and even guns raised to warn has increased greatly, so a batch of old guns were specially reserved to use when standing guard..."
Han Chenfeng nodded with a strange expression.
These contents can only be regarded as chatting, and there is no need to believe them.
It's just that it's really a bit unimaginable. What kind of external environment does sentries need to raise their guns frequently...
He thought that Liao Province in the 1990s was already very exaggerated.
But from this, it is indeed a slight witch.
In order to avoid the vehicle being driven and crashing, a section of road near the entrance of the factory was specially designed to be winding and twisty, making the vehicle speed never rise.
After a while, the whole picture of the core factory area was presented to everyone.
"You have even pretended to be the cooling tower?"
Han Chenfeng pointed to several abrupt cylindrical buildings in the distance. The white mist floating on the top of the tower was strange in the sunset. Lavender: "I thought it was a chimney when I looked outside..."
Peng Juexian nodded: "I did borrow some visual misalignment skills..." While speaking, the convoy had stopped at the front station of the third inspection, and the entrance to the underground project was also Finally it was truly revealed - the slope of concrete poured extends to the ground, and a lead-steel composite gate stands at the end of the slope, and the radiation meter at the top of the gate is flashing green.
"What is buried underneath is a national secret."
After brushing the pass, he turned around and whispered to Han Chenfeng, who had just changed into protective clothing and was wearing a dosimeter:
"Last year, a commercial satellite photographed a cooling tower, and it was said that we were working on a plutonium breeding reactor. Foreign affairs officers talked to them with fake drawings for three months, and finally they insisted that it was a potato starch production line..."
Han Chenfeng almost laughed out loud.
For intelligence analysis, many times, the greater the information, the better.
With the screening ability and data processing speed priority, excessively rich information can backfire, leading to wrong, or correct but useless conclusions.
As the last several tons of lead door slowly opened to both sides, the humid and hot air swept into the face with the low-frequency roar from the air conditioning equipment.
Han Chenfeng's pupils suddenly contracted -
Through the observation window of the control room, you can see that the cylindrical reactor container stands in the center of the distant semi-underground space, about half of the silver-gray control rod looks like a clock. The pointer hovered above the core, and the light blue Cherenkov radiant light spread through the observation window in the water mist. "Is this... a reactor?"
He studied nuclear physics and of course knew what it should look like in the reactor.
But in the past, I was not a nuclear power expert. The only nuclear energy project I had the opportunity to do failed halfway and was only at the design stage, so there were few opportunities to see it so directly.
Moreover, due to size problems, commercial reactors usually dig out a pool and soak them in. Even if outsiders visit, they can only look down from above.
This is the first time that angle like this is true.
"To be precise, it is a pool-type uranium-plutonium-zirconium alloy stack."
A technician in charge of guiding the route next to point to a row of seriously worn Russians on the base of the console. The seal of the CCCP can be vaguely seen: "This place was first built by the Soviets in the late 1950s to produce plutonium-239. It was upgraded and rebuilt on the basis of the original site in the 1990s, except for the fastest In addition to the preliminary technical demonstration of neutron reactors, they are mainly used to produce actinium-225 and strontium-89, and by the way, there is also a part of the actinium-252..."
"..." At this moment, Han Chenfeng instantly understood why this seemingly inconspicuous place had to be so heavily guarded:
"I always thought that the turret-252 was Production from Daya Bay? "
He knew that Daya Bay Nuclear Power Plant has an isotope production department, and on the order list of internal channels of the nuclear industry, the shipping place for isotope purchase and transfer is also in Pengcheng.
Now it seems that it is all a trick.
"You think so, that's right..."
Peng Juexian grinned at the corner of his mouth under the mask:
"Because we have always misled the outside world so much in the past, of course there are indeed some medical uses. And research isotopes come from there, but they are not mainstream."
Han Chenfeng stopped after hearing this, and his mind echoed with two words from the other person just now:
"Outside...Outside?"
He used to think that as the top leader of the 240s, he should be a well-known figure in the nuclear industry system.
It seems that it is still quite a bit short now.
Peng Juexian certainly didn't know that the sentence he had understateed had caused serious trauma to others' hearts, and he thought that the other party was puzzled by the behavior of "misleading" itself:
"You should know, As a neutron source, sulfon-252 has the function of inducing chain reactions. To some extent, it can reverse the level of nuclear energy research and construction through output, so it is more sensitive in engineering..."
The newest⊥small ⊥ Say⊥ Posted on ⊥Six⊥9⊥⊥Book⊥⊥⊥⊥⊥⊥!
Han Chenfeng actually understood this, but he didn't want to talk at the moment. He just approached the observation window a little closer to the observation window and watched the surface of the fuel rod soaked in the water was covered with honeycomb-shaped bubbles.
Suddenly, a crisp sound of dripping sound rang out, and the robotic arm grabbed a group of fuel rods and began to rise. The bubbles on the surface of the ingot burst into light golden sparks when they touched the air.
"A single production cycle can produce about 3 nanograms of oxidized-252."
Peng Juexian's voice was complicated:
"The annual output was less than 40 yuan. Micrograms, only about one-tenth of that in the United States... Nowadays, it seems to be too conservative, not even enough for domestic industrial construction purposes, let alone medical and other aspects..."
Han Chenfeng suddenly realized that the radiation meter on the cuffs of his protective suit was trembling slightly. He looked down and found that the second alarm light from left to right had already illuminated.
This level of radiation slightly exceeds the safety limit of the human body itself, but it is still within the protection range of protective clothing.
"So you want to use it as a plasma generator?"
His Adam's apple moved, and his voice seemed a little low due to the mask's obstruction:
" Directly convert nuclear fission into ionized gas, and then generate electricity through magnetic fluid... However, the temperature field distribution of this core does not meet the requirements at all. It is impossible for the water-cooled reactor to break through the boiling point, even if it is pressurized..."
Halfway through his words, he was interrupted by Peng Juexian: "Of course not."
After saying that, he turned around and gently patted the stainless steel shell of the console: >
"We are going to let it stop running and then transform it into a gas-cooled reactor in its entirety..."
"..."
For a moment, the air in the entire control room fell into solidification.
Han Chenfeng stayed in place, his eyes widened slightly under the all-inclusive protective helmet, acting even more shocked than when he heard that he was an "outsider".
After a long time, I put on a tone:
"Ah?"
Peng Juexian gave a standard reply:
"What?"
"The gas cooling technology of small research reactors is relatively mature, and reactors of similar scale have long been used to verify high-temperature gas cooling technology in foreign countries, which is the most important thing at this stage A safe solution, you can't really take risks with the HTR-10 high-temperature air-cooled test reactor, right? "Han Chenfeng shook his head quickly, and his movements were a bit funny due to the heavy head protection:
"I mean, are you going to dismantle it like this?"
He knew that the project he had endorsed by Academician Chang, so the priority should be very high.
But I never thought that the above would agree to stop isotope production directly.
"Of course it's impossible..."
Peng Jue first carried his hands on his back, and a light flashed across his eyes:
"Academician Chang has agreed... Let's report together , strive to build an isotope production base with a larger scale and higher production capacity. ”
