After reading the secret reports of Feiyu Company and Qingye Airlines, Li Qingye saw another good news.
This good news was reported from the Black Tiger Canyon.
Over there at Black Tiger Canyon at this time.
Dr. Levi's is in the "Mining Zone."
The so-called mining area is actually a hidden underground experimental site. On the surface, this site is a lead-zinc mine belonging to Qingye Mining Company.
Explosives are often detonated to create seismic waves, disguised as signs of mining underground minerals.
For explosions of several hundred kilograms, the subtle seismic waves generated will generally not arouse suspicion, although they will be detected by seismic monitoring stations.
The underground of this "mining area" has long been hollowed out and turned into an experimental site. In addition to an underground tunnel, there are 5 underground spaces of different sizes.
At this time, we are in Experimental Field No. 3.
Dr. Levis, along with his colleagues and scientific research assistants, were busy assembling a basketball-sized device.
The core of the device is a small vacuumed space, which is about the size of a sesame seed.
Surrounding this ultra-small sub-vacuum space are 16 cones. The tops of these cones have a device similar to the nib of a ballpoint pen. The "ball" clamped by the "nib" is a mass.
0.01 grams of uranium 235 with a purity of 99.99%.
In other words, the uranium fuel for this device is 0.16 grams.
The remaining space in the cone was filled with TNT explosive, a total of 4.8 kilograms of TNT.
A sphere composed of 16 cones is wrapped in a layer of composite material with a thickness of 30 mm.
The innermost layer of this composite material layer is an alloy radiation reflective layer, the middle is a high-temperature-resistant composite ceramic layer (can withstand a high temperature of 5836 degrees Celsius), and the last outer layer is a super-strong one-piece alloy, which is enough to withstand the internal TNT explosion for 3.2 seconds.
The innermost alloy radiation reflection layer has another very special function, which can mutate into a superconductor under ultra-high pressure.
At the same time, metal powder is added between the TNT and the gold alloy radiation reflection layer, which will generate a large amount of electron flow at the moment of explosion, which will then excite the mutant superconductor and form a strong magnetic field that will restrain the explosion for 3.2 seconds.
In other words, after detonating the TNT core, the entire explosion energy will be trapped inside the sphere for 3.2 seconds.
Don't underestimate these 3.2 seconds. It is because of these 3.2 seconds that the uranium 235 beads at the top of the cone are instantly squeezed into the sub-vacuum space by high temperature and high pressure, thus forcing intense nuclear fission between the uranium 235.
Due to the existence of the magnetic field, the energy of the nuclear explosion was not released immediately, but was squeezed in the core area.
The advantage of this design is that the fuel utilization rate of nuclear fission rises sharply, and the critical mass of nuclear fuel explosion can be reduced to the level of several milligrams.
The "Firefly" No. 3 in front of us is the ultra-small atomic bomb secretly developed at the Black Tiger Canyon Base.
This is also one of the few solutions selected by Levi's and a group of scientific researchers, combined with various new materials from the Homo sapiens company, and after conducting tens of billions of supercomputer simulations.
The entire Firefly 3 weighs 17.3 kilograms, is equipped with 0.16 grams of uranium 235 with a purity of 99.99%, has an explosion yield of 2.72 tons, and a nuclear fuel utilization rate of 85.6%.
After assembly is completed.
Levis and others, wearing protective clothing, left the experimental site and came to a special data monitoring room.
"The third test begins."
"Start the transport system."
The electric rail car carrying Firefly 3 slowly drove towards the test explosion site of the experimental site.
The entire test explosion site is 343 meters deep underground and is a hemispherical cavity with a radius of 50 meters. There are several layers of artificial structures around it to reduce the explosion shock wave.
"Detonate!"
3.2 seconds later.
boom……
A small fireball exploded in the center of the test explosion site, followed by optical radiation, ionizing radiation, thermal radiation and shock waves.
Various data collectors feed back the detected data to the biological computer in the monitoring room.
The seismic wave monitoring equipment installed in the surrounding areas only detected a weak seismic wave with a power of only a few hundred kilograms of TNT.
But in fact, Firefly 3 produced an explosive yield of 2.72 tons of TNT.
After reading the data, Levi nodded with satisfaction: "The firefly-type ultra-small atomic bomb is now ready for mass production."
"The next step is to improve the old warhead." Another researcher said.
The reason why they developed this ultra-small atomic bomb was mainly for three purposes.
One is for conducting nuclear explosion experiments.
This goal has been achieved. They successfully conducted three ultra-small nuclear explosion tests at the underground experimental site near Black Tiger Canyon.
The outside world knows nothing about this.
The core factor why it can be concealed from the outside world is that the explosion yield is small enough, with an average yield of only a few tons. Coupled with the shock-absorbing structural layer of the experimental site, even if the outside world detects it, they will only think that it is blasting underground minerals.
The second purpose is to improve nuclear fuel utilization.
At present, Homo sapiens can refine 150 to 180 kilograms of uranium 235 per month, which can probably produce three atomic bombs with a yield of 300,000 tons (Liehe 30). A single Lieutenant 30 requires 52 kilograms of uranium 235 raw materials, and the nuclear fuel utilization rate is only 30%.
.
There are currently 42 Liege 30 in stock, and there are also 283 kilograms of high-purity uranium-235 raw materials.
After switching to the new configuration of the Firefly type, it also achieved an explosion yield of 300,000 tons, but the Firefly type only required 18 kilograms of uranium-235 raw material.
This means that after all the Liehei 30s currently in stock are transformed into Firefly atomic bombs, approximately 120 Firefly atomic bombs with a yield of 300,000 tons can be produced.
The third purpose.
It was to improve the atomic trigger of the B43 hydrogen bomb. After all, the B43 atomic trigger was designed by America more than fifty years ago. Not only was there a serious waste of nuclear fuel, but the radioactive pollution was also relatively high. It also used plutonium as the raw material.
Levis not only plans to use a Firefly-type atomic bomb as a hydrogen bomb trigger, but also plans to improve the configuration of the B43.
Early hydrogen bombs such as the B43 often had a relatively low nuclear fuel utilization rate, only about 15% to 20%.
The Liehe 100 model, which is imitated by B43, currently requires 50 kilograms of deuterium as raw material to achieve an explosion yield of one million tons.
Through supercomputing and the current firefly atomic bomb explosion experiment, Levis has found the direction of miniaturizing the hydrogen bomb and also found a solution to improve the fuel utilization rate of the hydrogen bomb.
The miniaturized hydrogen bomb is estimated to have a minimum explosion yield of 1 ton (the atomic trigger generates 350 kilograms of TNT energy), but the volume is difficult to compress and the weight is about 20 kilograms.
According to the models and data simulated by Levis and others in supercomputers, the fuel utilization rate of the Firefly-type hydrogen bomb can also reach about 80 to 90%.
If the charging capacity of 50 kilograms of deuterium is still maintained, the power can reach approximately 6.3 million tons equivalent, which is a full increase of 6.3 times.
This power is obviously excessive, and the weight of the warhead is 900 kilograms, which is not conducive to lightweighting.
Dr. Levis has been discussing with engineers in the nuclear engineering department to develop a new warhead with a yield of 100,000 tons and a weight of less than 100 kilograms.
This is also the core idea of the current great powers, which is to use hydrogen bomb warheads with an equivalent of hundreds of thousands of tons, and then load several sub-warheads into one missile.
Ten hydrogen bombs with a yield of 100,000 tons are several times more lethal than one hydrogen bomb with a yield of 1 million tons.
From a cost-effective perspective, medium-yield cluster hydrogen bombs are currently the mainstream solution.
The firefly hydrogen bomb has another advantage, that is, the reaction is more complete, resulting in an even lower amount of radioactive material remaining, and it can basically be called a clean nuclear bomb.
