Chief Accountant: "It's like the model of our tungsten mine, right? No, it's been four years since the Soviet Union exploded the atomic bomb. They should have uranium mines in their country, right?"
Tang Hua: "The big uranium mine...there really isn't one."
There are large-scale (70-ton and above) uranium mines in the Soviet Union, but they were discovered relatively late in exploration.The Soviet atomic bomb was supported by several thousand tons of small uranium mines discovered at that time, and then supported by uranium mines in North Korea. It was not until the [-]s that large domestic uranium mines were discovered.
In 1953, it was the time when the Soviet Union exploited North Korean uranium mines.
North Korea is a small place with rare world-class uranium mines. In 1964, a total of 400 million tons of high-grade uranium ore were found, equivalent to 3.2 tons of natural uranium.In fact, 2.7 tons were finally mined (the grade of some parts of the vein is estimated to be optimistic), but the average uranium content of the ore is as high as 0.7%, which also belongs to the high-grade uranium ore.
But now in 1953, the Soviet Union’s total reserves of North Korean uranium mines were not as solid as they were in 1964. The Soviet Union believed that the credible reserves of North Korea’s ore deposits were only four to five thousand tons.An obvious evidence is that the small and medium-sized uranium mines in the Soviet Union are also fully digging at this time.
Then at this time, China discovered a shallow uranium deposit with a reserve of 1.3 tons and an average grade of 0.42%. China expressed its willingness to cooperate with the Soviet Union, and the Soviet Union certainly could not refuse.
Tang Hua: "There are not too many uranium mines explored in the Soviet Union at present, and the content of the mines is also low. The Soviet Union has been investing in the development of uranium mines in North Korea for the past two years. It is using North Korean uranium to develop the nuclear industry. We also have quite a few Because of North Korea’s reserves, our uranium mines are in Jiangxi, this area is safer than North Korea, the Soviet Union will definitely not refuse,”
Chief Accountant: "Will the Soviet Union just ask us to mine and they import the ore?"
Tang Hua: "Uranium ore is a kind of ore with very low effective content. There are very few ores with a content of more than 1%. If the grade is greater than 0.6%, it is considered a rich ore. Therefore, it is very difficult to transport tens of thousands of tons of uranium ore back and forth by train. It is not cost-effective, usually smelted on site in the mining area to produce an intermediate product with a content of 60% to 80% U[-]O[-], commonly known as yellow cake. Then the Soviet Union shipped back a total of hundreds of tons of yellow cake this year for use. "
Li Siguang: "Xiangshan Uranium Mine can be built into a mine that excavates 5 tons of ore a year, and produces 350 to 5 tons of yellow cakes each year, which are exported to the Soviet Union. The investment in the mine and smelter can be recovered in 8 to 5 years. The cost, after that, is the net profit of foreign exchange. Then if we want to use uranium in the nuclear industry, of course we can also produce yellow cakes from mines. We only need to expand the production capacity and expand the annual output of ore from 10 tons to [-] tons. question."
"Wait a minute," the chief accountant turned back to the previous page, "Xiangshan Uranium Mine has a proven ore reserve of 300 million tons. If we use it together with the Soviet Union in the future, won't it be exhausted in 30 years?"
Tang Hua: "The Xiangshan uranium mine is only a shallow ore of 300 million tons. Minister Li also found that there are other potential ore veins in the Xiangshan area. There is a great possibility that new reserves will continue to be discovered. It will take 30 years. Moreover, with more than 900 million square kilometers of land in China, it is impossible to have only this one big uranium mine.”
Li Siguang: "In the future, the Ministry of Geology will continue to devote energy to searching for special mineral deposits, and there will be no gains."
By the 20s, China had discovered 80 tons of uranium mines, known as the three "uranium capitals".By the 21st century, the number of uranium mines with reserves of more than 7 tons has increased to seven.It is just because China, as the top five hooligans, buys yellow cakes in the international market completely legally and no one stops them. Therefore, yellow cakes are generally imported for isotope separation to supply uranium for commercial nuclear power plants. Local uranium mining is not very strong.
It is the same in this world. Sooner or later, China will freely purchase yellow cakes in the international market.
Chief Accountant: "...Well. This news is too important to go to Beijing to report to the Prime Minister in person. No, to report to the Chairman."
Tang Hua: "The Bureau of Electronics and Information Industry and the Bureau of Shipbuilding Industry still have a lot of things to do in Shanghai. It is enough for Minister Li to report back. Just write down the suggestions I just made and send them up together."
……
Gold II and Gold III began to engage in nuclear weapons in the 90s, which was actually the foundation of the large uranium mine built with the aid of the Soviet Union.
The uranium mine was built, and the raw materials for nuclear weapons were resolved.The uranium ore needs to be smelted on the spot, and the first small step of the nuclear industry is done.The factories that smelt yellow cakes need talents, so since the 60s, North Korea sent many college students to the Soviet Union to study nuclear physics. North Korea engaged in nuclear engineering in the 90s, and the backbone of the team was nuclear physics students who went to the Soviet Union to study in the 6s and 70s.
In China, the current source of nuclear physics talents is actually not bad... There are high-end talents.Zhao Zhongyao is cultivating popular talents at Tsinghua University. Since 1954, he has been able to graduate a group of fresh graduates from the Department of Physics every year.
Leveraging the Xiangshan uranium mine to invite the Soviet Union to build a uranium mine and a yellow cake smelter, the main reason is to shorten the time spent on the nuclear program.These two plants are not high-end in the nuclear industry system, but they still account for about 20% of the workload.When the nuclear weapons program is officially launched, do 20% of the work first, then the whole plan will become smooth.
"Minister Tang, we have entered the outfitting stage for the first ship of the Type 01 frigate, and about 80% of the work has been completed. The navy's receiving force has been formed and has arrived at the Jiangnan Shipyard. If all goes well, the first Chinese frigate will be ready by the end of this year. The built missile frigate can go to sea for sea trials."
Cheng Wang and Tang Hua were beside the 01-ton large dock of the Jiangnan Factory, looking at the first Type [-] frigate that had been towed to the side pier for outfitting.
The first frigate built in China is a guided missile frigate.
Absolutely.
Tang Hua has already seen the YJ-01 anti-ship missile launcher in the middle of the Type 1 frigate on the outfitting dock—of course, the loaded missile storage tank should be a model.
With a full load displacement of 1300 tons, it is a little bit reluctant to install anti-ship missiles and anti-aircraft missiles at the same time, so the Type 01 frigate only has anti-ship missiles.The installation method is very simple, just remove the rotating torpedo tube in the middle and install two quadruple YJ-1s, and it will be done.
"If everything goes well, of course, but we also have to be prepared to rework certain tasks," Tang Hua said. "After all, this is the first time we have built a modern thousand-ton warship, and we are still in the original Soviet version. So many things have been changed on the drawings... After the outfitting is completed, the dock mooring test and the subsequent factory test must be done honestly, and problems can be found and solved in time, so that the subsequent No. 2 and No. 3 ships can Adjust to avoid these problems at build time."
Cheng Wang nodded. "By the way, Minister Tang, the Type 01 frigate's anti-ship missiles are installed like this. When attacking an enemy ship, it is necessary to turn the ship sideways and launch four. If it is not enough, the ship has to be turned 180 degrees. Can we launch the other 4?"
...Now there are 8 launchers in two quadruple installations, four facing the port side and four facing the starboard side, all perpendicular to the longitudinal axis of the ship. The missiles that the 31 ships and 32 ships collided with were slanted 45 degrees ahead.So it's not surprising that Cheng Wang asked such a question.
Tang Hua: "Now the missile has been modified. After launching, the missile will turn according to the program control and then fly to the target. The maximum turning ability can be 120 degrees, so the freedom of the Type 01 missile attack is very large. What angle the warship is placed It's not too important. Old Cheng, didn't you say that Shigeru Makino is in the Jiangnan factory? Where is he?"
Chapter 6, Things Shigeru Makino Has Never Seen
Shigeru Makino is now in the Jiangnan factory.But not in the dock and dock area of the Type 01 frigate.Not in the shipyard area either.
Because Makino Shigeru's political review procedures have not yet been completed...
In the ship repair dock of the Jiangnan Plant, Shigeru Makino chatted with comrades from the Shanghai Ship Design Institute facing a 6500-ton civil bulk carrier that was being repaired here.
"...a bulk carrier is a very standard displacement ship with a single deck and double bottom. Most bulk carriers of this tonnage have a single shaft, so the shafting is not of much reference to warships."
"...If you want to design warships based on the structure of a cargo ship with a capacity of [-] tons or more, then you will often get twice the result with half the effort."
Shigeru Makino said something, and the translator next to him repeated it in Chinese.
In addition to Shigeru Makino and the translator, there were eight or nine (intern) designers from design institutes in this group, discussing issues around the propeller of the bulk carrier.
Tang Hua originally wanted to quietly approach and listen for a while, but Cheng Wang was behind him, and he followed the two guards inseparably. This was arranged by the Prime Minister himself, and he was not allowed to leave these two behind.
He was discovered just after listening to a few sentences, and a group of people from the Ship Design Institute gathered around to say hello.
"We haven't seen each other for half a year," Tang Hua said with a smile, "We had dinner at Hudong Zhonghua's Jiangnan factory on New Year's Day and Spring Festival this year."
Take a closer look, apart from Li Fuli, Zhao Renkai and Huang Xuhua, there are one or two new faces in this group.
"Mr. Tang, hello. I'm Pan Jingfu. I'm from the 52nd class of Zhejiang University." A thin and small man, he looks like a young student who hasn't graduated long ago. , was transferred to the Shipbuilding Industry Bureau in March."
Tang Hua and Pan Jingfu shook hands.
...The current ship design institute seems to be full of big names, who else is worse?Probably only Peng Shilu and Yan Baoxing, who were studying in the Soviet Union, were missing.
……
"Hello, Mr. Tang Hua." Shigeru Makino waited for Tang Hua and several people from the Ship Design Institute to finish greetings before walking forward and bowed slightly.
"Mr. Makino Shigeru? Hello." Tang Hua shook hands and carefully looked at the 51-year-old Japanese uncle.
"It is a great honor to meet the King of Science and the Minister of Heavy Industry in China," said Shigeru Makino.
Unexpectedly, the publicity reports of the year before and last year to boost morale and build confidence and self-improvement among the people also caused a fan-gathering effect overseas. This should be an unexpected harvest for Tang Hua and the Central Propaganda Department.
"I am also honored to meet the chief builders of Yamato and Musashi."
"This is my first time in China," Makino Shigeru said, "so everything feels very fresh. Although the political review still needs time to go through the process, I have been hired as a foreign consultant for the Shipbuilding Industry Bureau and can enter the shipyard Knowing the status quo of China's shipbuilding industry, ... it is indeed a growing emerging force."
Tang Hua said with a smile: "'The emerging power that is growing' is euphemistic, but it does point out our current situation. Yes, we can now build speedboats, minesweepers, and frigates. That's all. Actually The existing berth in Shanghai can support the construction of destroyers of three to four thousand tons, but our upstream infrastructure such as steel, metallurgy, machinery, and power has not kept up, so even destroyers will not be available until two to three years later. conditions of construction."
Makino Shigeru: "Destroyers are almost enough. If we can go a step further and build light cruisers, then it is completely enough for the post-war navy."
Tang Hua raised his eyebrows.It seems that the chief teacher of Yamato actually has some ideas in his heart.
"Mr. Shigeru Makino is the chief engineer who has designed a [-]-ton battleship. It really impresses me to be able to say this."
"Before the construction of Yamato and Musashi was about to start, I proposed some modifications to the design of the Yamato-type ship, which could reduce the weight and significantly increase the survivability of this type of battleship. Unfortunately, my suggestions were not taken seriously by the higher-ups." Shigeru Makino Said, "After the outbreak of the Pacific War, I also opposed the continued construction of giant battleships. However, this is a matter of national decision-making and I cannot influence it. The [-]-ton battleship is outdated, and the masters of naval warfare are aircraft carriers and aircraft. Surface combat Ships need to assist and cooperate with aircraft carriers in operations."
