Chapter 1380 Isotope Production Reactor


    On the hillside in the western suburbs of Jincheng, the blue steel tile roof of the Nuclear Industry 504 Factory workshop is looming in the twilight.


    Peng Juexian pushed his glasses, looked at the barbed wire and warning signs passing through the car window, and suddenly spoke:


    "Fifteen years ago, when I first came here, the guard battalion here was not equipped with automatic rifles, 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.


    However, before the speech was opened, 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    "Actually, it has been replaced by 95, but the main function of the whistle at the door is to shock and warning. After using it, I found that the new gun is too short and the plastic feel is too heavy. When I hold the gun, I cannot see the magazine from the front because my arms are blocked... In short, the deterrent power is insufficient, resulting in a large increase in the frequency of sentry commands and even raising guns to warn, so a batch of old guns were specially reserved for use when standing guard..."


    Han Chenfeng nodded with a strange expression.


    These contents can only be regarded as casual chats, and there is no need to believe them.


    It''s just a bit unimaginable. What kind of external environment does sentry need to raise their guns frequently...


    He thought that Liao Province in the 1990s had been very exaggerated.


    But from this perspective, 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''ve even pretended to be the cooling tower?"


    Han Chenfeng pointed to several abrupt cylindrical buildings in the distance, and the white mist floating on the top of the tower was shining with a strange lilac color under the setting sun:


    "I thought it was a chimney when I looked outside..."


    Peng Juexian nodded:


    "I did borrow some visual misalignment techniques..."


    While speaking, the convoy had stopped at the front station of the third inspection, and the entrance to the underground project was finally revealed - the **** of the concrete poured is extended 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 stands. A green light flashed.


    "What is buried under this is a national secret."


    After finishing his 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 said that it was a potato starch production line..."


    Han Chenfeng almost laughed out loud.


    For intelligence analysis, it is not often the greater the amount of information, the better.


    In the case of priority of identification and data processing speed, overly 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 the cylindrical reactor container standing in the center of the distant semi-underground space, about half of the silver-gray control rod hovering above the core like a clock hand, and a light blue Chellenko The radiant light spreads through the observation window and spreads into the mist.


    "Is this... a reactor?"


    He studied nuclear physics and of course knew what the reactor should look like.


    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 this angle is now.


    "To be precise, it is a pool-type uranium-plutonium-zirconium alloy reservoir."


    A technician in charge of guiding the way next to him pointed to a row of heavily worn Russian nameplates on the base of the console. You can vaguely see the steel seal of the CCP:


    "This place was first built by the Soviets in the late 1950s to produce plutonium-239. It was upgraded and rebuilt on the original site in the 1990s. In addition to conducting preliminary technical demonstrations on the fast neutron reactors, it is mainly used to produce actinium- 225 and strontium-89, and by the way, there is also a part of the 252..."


    "..." At this moment, Han Chenfeng instantly understood why this seemingly inconspicuous place had to be so heavily guarded:


    "I always thought the calder-252 was produced in Daya Bay?"


    He knew that the Daya Bay Nuclear Power Plant had an isotope production department, and on the order list of internal channels of the nuclear industry, the delivery place for isotope purchase and transfer was also in Pengcheng.


    Now it seems that it is probably a trick.


    "It''s right you think so..."


    Peng Juexian hid under the mask and grinned:


    "Because we have always misled the outside world so much in the past, of course, there are indeed some medical and research isotopes coming from there, but they are not mainstream."


    After hearing this, Han Chenfeng stopped 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 there is still a lot of difference now.


    Of course, Peng Juexian 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 that as a neutron source, sulfonium-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 ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!


    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 ng of calc-252."


    Peng Juexian''s voice was filled with complex emotions:


    "The annual output is less than 40 micrograms, only about one-tenth of that in the United States... It seems that it is still too conservative now, and it is 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.


    The radiation level at this level 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:


    "The nuclear fission is directly converted into ionized gas, and then generated 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''re 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 in a tone:


    "ah?"


    Peng Juexian gave a standard reply:


    "Ah 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 abroad. It is the most secure solution at this stage. You can''t really use HTR-10 high-temperature Let''s take the risk, is the air-cooled test reactor?"


    Han Chenfeng quickly shook his head, and his movements were a bit funny due to his heavy head protection:


    "I mean, are you going to just tear it off like that?"


    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... We both report together and strive to build an isotope production base with a larger scale and higher production capacity."
