Chapter 513 The Biggest Obstacle
Some units want to publish the list before the superior department, while some units do the opposite, after the superior department.
This is not to follow the footsteps of the superior department, but on the contrary, it is to avoid the commendation and award list of the superior department, so that it can be divided more evenly, that is, those who have been commended by the superior will not be included. The rewards for this level are limited, and will be replaced by those who follow.
On the one hand, it shows respect for the superior department, and on the other hand, it saves resources. Yes, rewards and commendations are also an out-and-out resource.
Both methods have their own reasons. The third rolling mill chose the latter according to the habits of the third rolling mill.
As for the timing of these events last year, it was confusing because the Agni Technology Award suddenly appeared and there was no news about it before that.
As for the fact that the Agni Technology Award has not appeared this year, it is not because of difficult labor, but because the 17th Machinery Department has been held back by several things.
First, in the 6011 battle, Gao Zhendong, together with the third rolling mill Jingang Steel Works, produced the first batch of results extremely quickly, which made comrades in other units secretly frightened and suppressed. He was full of energy and rushed forward with all his strength, which made many judges of the Fire Award themselves be held back. They also had battle tasks.
Secondly, the Seventeenth Machinery Department has a major special task to participate in. Although it is not the protagonist, it must cooperate fully. This has held back another group of people. This group of people who are held back are not the judges, but Potential winners, if the prizes are given out at this time, the venue may be quite empty.
The third reason is not very formal or serious. The 17th Machinery Department heard that the 12th Machinery Department also launched some kind of "Lightning Technology Award", and I wanted to see if the 12th Machinery Department would give it to them. Who, if it was not sent to Gao Zhendong, then the 17th Machinery Department would have to evaluate the projects related to the 12th Machinery Department this year, such as Gao Zhendong's pile.
It happened that the 12th Machinery Department was doing it for the first time this year, and it was a little slow, so it delayed this whole series.
But no matter how much we delay, by the end of February, starting from the No. 3 Factory, this matter has to be done anyway. At that time, we can’t care about wasting resources, respecting our superiors, etc. There is no longer the issue of taking care of the face of other ministries.

Deep in the desert, there is a testing ground. This place has been filled with rumbling explosions and smoke for many years, every day, without stopping.
This is not about breaking mountains and cracking rocks for construction, but about constantly doing detonation experiments.
The little boy and the fat man who once burst out with great enthusiasm over the little devil have the same principle. Apart from the commonality of the neutron source in the center, both of them form a chain reaction by making the charge exceed the critical mass. The charge that triggers the final explosion may be "by" or "not", but the little boy and the fat man achieve it in different ways.
The Little Boy is a gun type. Simply put, it divides the charge into two halves. When detonating, use explosives to shoot one charge towards the other to achieve the purpose of super-criticality.
The advantage of this configuration is that it has a simple structure and is easy to implement. There are many disadvantages. The charge utilization rate is low, the power is small, and it can only be used for "by" charging, and cannot be used for "not" charging. "No" charging will cause uncontrolled premature explosion.
How simple is the structure of this thing is that in the future, it is not too exaggerated to say that as long as there is a sufficient abundance of charges and neutron sources, high school students can grind big mushrooms.
Fat Man is cohesive, which is much more complicated.
A cohesive charge can be roughly thought of as dividing a sphere into many pieces to surround the neutron source. The outside of the charge is a neutron reflecting layer, and then outside is a high-speed explosive. This thing sounds better than a gun-type charge. It's not the least bit complicated.
When detonating, the surrounding explosives explode together, and at the same time the charge is squeezed toward the neutron source, reaching a supercritical state.
The purpose of the neutron reflective layer at this time is to reflect back the neutrons produced by the chain reaction, aggravating the chain reaction.
Such a complex method naturally has great benefits. To put it simply, it means that the charge utilization rate is high, the same charge will explode louder, and it is suitable for a variety of different charges.
It is important that this applies to a variety of different charges, because "un" charges can be produced directly by utilizing other elements through nuclear reactions.
These things are public, not to mention that they will be available everywhere on the Internet in the future. Even in my country in the 1970s and 1980s, these principles were written in "One Hundred Thousand Whys" for children.
Don't talk about this, even the principles of two-phase bombs and three-phase bombs are all there. Their titles are probably "Why do atomic bombs explode", "Why are hydrogen bombs so powerful", "Why are three-phase bombs so powerful?" The bullet is more powerful."
There is no doubt that our choice is naturally cohesive.
This is the reason why this test site is non-stop and rumbling all day long. They are testing.
The principle of cohesion may not seem complicated, but in fact it is not that simple.
For example, there is something that seems simple, but actually requires a lot of effort to achieve: making all parts of a spherical high-speed explosive detonate evenly and at the same time.
As for the specific configuration of the cohesive type, it has to be forgotten. Fortunately, with the help of a large number of DJS-59 and DJS-60D produced by Gao Zhendong, the configuration was decided two years in advance. The type is calculated.
But just calculating it is not enough, you also need to experiment. There is a difference between theoretical calculation and actual situation. You have to conduct experiments, collect experimental data, and then make adjustments.
This is a job that takes a lot of time and cannot be accomplished overnight. Computers are not omnipotent. Even in the 21st century, they still cannot simulate and calculate everything.
It’s like even though we have the NS equation proposed in 1845 and combined with the supercomputers of the 21st century, aerodynamic design still has to rely on blowing in a wind tunnel. Our wind That's what the caves are for.
This test site is responsible for the detonation experiments of explosive configurations, so you should not hear the noise every day. In the early days, before the production of Heihan-60 climbed, basically all the production was swallowed up by this test site. Fortunately, although computers cannot handle everything, they are good at assisting in data processing. For humans, even if the formulas are the same, but the data has changed, then every calculation is a new process.
But for computers, the trouble lies in programming. Once the program is fixed, changes in data are not a big problem for it.
In a building next to the detonation test site, several scientists in charge of the experiment were sitting next to the printer, waiting for the computer to output the results.
“This computer is good and can calculate quickly. I never imagined that after collecting the data, it could calculate the results so quickly and write them down on paper for you.”
"Haha, we are working hard, and other scientific comrades outside the desert are not idle either. They are constantly contributing to us."
Several comrades were chatting, and the computer suddenly made a beep. There was a prompt, and at the same time, the printer began to "sizzle" and spit out paper one by one.
Several scientists were in a hurry. When the printing paper spit out a piece of paper, they grabbed one in their hands and looked at it one by one.
The printing paper was circulated in their hands for a long time. Several people raised their heads and looked at each other, their eyes full of light.
“It’s done!”
"No problem!"
"It works!"
Although the words are different, the meaning is the same!
The charge configuration is completed!
This charge configuration is not only the configuration of the outer explosive, but also the configuration of the internal charge, which is related to how they move under the impact of the explosive, how they aggregate, etc.
The comrades at the test site spent so long that they almost had hearing problems, just for this day - the detonation experiment was successfully completed!
"Go, let's take this news to the main building."
Several people hurried to the main building with the test results.
It is said to be the main building. In fact, there is no convention that the "main building" must be majestic or taller in the future. The main building is mainly because of the different people and work inside. In fact, from the outside, it looks similar to other buildings. An eye-catching look.
Several people found an office and handed the test results to a comrade inside.
"It's done! The detonation is done."
The comrade stood up immediately, quickly took the test results from their hands, brought them to his eyes, and read them carefully.
After a while, the comrade slapped the table: "Okay, the biggest obstacle has been killed by us!"
After speaking, he looked at several comrades who came over: "Now , the biggest remaining problem lies with the centrifuge group. "
The core elements in the charge have multiple isotopes, but in order to explode, you can only use one of them. They are all isotopes, but in natural ores, these isotopes are mixed together because they have similar chemical properties.
This similar chemical property also makes the separation of isotopes very difficult, and chemical methods will not work.
At this time, there are no value-added reactors, and there is no way to use other elements to directly obtain charges.
However, the most high-end ingredients always use the simplest cooking methods.
If chemistry doesn’t work, then use physical methods to shake it up.
Use a centrifuge to separate different isotopes based on the principle that isotopes have different atomic weights and different physical properties.
However, not one or two centrifuges of this kind can complete this task. It would take a large group and a large area to collect a sufficient amount of materials.
This thing is large in quantity, very power-consuming, and costly. If we can get the power consumption data, we can really calculate how much raw material is produced.
Of course, in the 21st century, there are still people who say that we can use electricity consumption data to estimate how much raw materials we produce and how many warheads we have. That is nonsense.
In the 21st century, this small amount of electricity is not even a fraction of our power generation, and the power curtailment caused by frequency and peak regulation and peak-valley differences is more than this. Moreover, the raw material production technology at that time was not necessarily the only one.
