The First Law of Thermodynamics:

Heat can be transferred from one object to another and can also be converted to and from mechanical energy or other energy, but the total value of the energy remains the same during the conversion process.

Plasma cutters are also one of the thermodynamic expressions.

The energy module that supplies the power supply to the plasma cutter also follows the principle of conservation of energy. Its energy storage density is directly related to the working time of its drive plasma cutter.

A nuclear reactor, strictly speaking, is also an energy storage device, but the energy density is many times higher than that of the energy module.

It relies on the fuel rods in the core to provide a continuous heat source, which heats the primary circuit cooling water, and then boils the secondary circuit working fluid water into an ultra-supercritical fluid to drive the gas turbine to generate electricity.

Why did Electrocrystal design the amorphous torpedo into a thousand-ton big guy in the first place?

In order to be able to barely cram into a small nuclear reactor.

Reactors generate electricity, and with electricity they can drive various equipment or weapons.

If the plasma cutter is driven, the reactor can provide almost unlimited power, allowing the plasma cutter to cut through the hull at will.

So......

Under the principle that plasma uses a high-temperature arc to melt metals, these energy conversion steps are directly skipped, and what cores, reactors, primary circuit water, secondary circuit water, and gas turbines are skipped.

Just bare-knuckled with a fuel rod?

What happens if you hold a fuel rod?

Normally, of course, it is the internal nuclear fuel of the fuel rods that gradually heats up and releases some radioactive elements that can penetrate the protection of the zirconium alloy fuel rods.

In the absence of cooling measures, it will gradually rise to a high temperature of more than 3,000 degrees, melting itself while melting the zirconium alloy to protect the shell.

Once the uranium dioxide fuel block inside is melted, its fission reaction can no longer be artificially interrupted.

The fission knife was an extreme weapon that Ye Qing thought of.

There are no messy energy conversion steps, just redesign a fuel rod and turn it into a weapon that can continuously unleash terrifying heat.

Plasma cutters can release an electric arc of up to 8000 degrees to melt the metal.

A fuel rod, although there is no way to heat the temperature to 8000 degrees.

However, energy is conserved.

There is a loss in the energy conversion process, and the more conversion steps, the greater the loss.

The heat utilization rate of nuclear power generation is only 33%, and the electricity is converted into a high-temperature arc through the plasma cutter, and the energy loss is further increased.

Therefore, in the end, the destructive power of the arc is simply not comparable to the destructive power of the thermal energy released by the fuel rods.

……

As soon as Ye Qing's fission knife plan was proposed, Dianjing exclaimed in amazement, and felt that he had a very, very good appetite for himself.

How big is a fuel rod?

The standard fuel block in a nuclear power plant is a cylinder with a diameter of 1 cm and a height of 1 cm. Hundreds of these fuel blocks, encased in a 1 mm thick zirconium alloy material sleeve, form a standard four-metre-long fuel rod.

Then redesign, design the fuel rod as a knife filled with hundreds of fuel blocks.

Before cutting, activate the fuel block in the fission knife and ignite it, allowing it to continuously release terrifying heat.

Of course, once the fission knife is activated, there is no way to lower the temperature again. Without cooling, it won't take long for it to melt itself down, causing a nuclear leak.

"That's not a problem!" exclaimed.

If it can't be extinguished after activation, then it won't be extinguished.

After the task of cutting the warship is completed, the amorphous torpedo will be removed from the fission knife and placed on the submarine. The submarine is large enough and hidden in the sea, and the direct water circulation can continue to cool the fission knife.

When you use it next time, just take it out and put it on.

As soon as the design idea of the fission knife was proposed, everyone from Ye Qing to the electrocrystal to the delicate master became extremely fanatical, and now where did they still have the heart to manage the cargo problem on the humpback whale.

Ye Qing directly activated the lord warship and returned to the secret factory behind the Suotu rainforest, where there was a nuclear reactor and a large amount of fuel blocks.

Less than twenty minutes away from returning to the nuclear plant, Electrocrystal has already begun to design the shape of the fission knife.

First of all, you need a metal that is more resistant to high temperatures and corrosion than zirconium alloys.

Humans use zirconium alloys to make fuel rods, which does not mean that zirconium alloys are the most high-temperature resistant alloys that humans can make.

However, zirconium alloy has high hardness, high ductility, and corrosion resistance, and it can maintain its strength in long-term high-radiation and high-corrosion environments.

In addition, its fusion welding performance is quite good, and it can be easily welded into various components, so it is the most suitable material for making fuel rods.

Dianjing was just about to use his holographic glasses to flip through the alloy metal catalog in the factory, when he suddenly slapped his transparent head.

What alloy is used, directly use amorphous metal.

The zirconium alloy fuel rods used in commercial nuclear power plants will slowly climb to about 3,000 degrees Celsius once the fuel rods lose their cooling water to cool down and are not stopped reacting. At this temperature, the zirconium alloy will not last long before it will be melted off.

The amorphous metal is the alloy with the highest known melting point, which has a melting point of 4622 degrees.

And when the melting point is reached, it just can't go into the solid state anymore. As soon as the temperature drops, it can switch between two of the three forms of metal at will.

The denser the metal, the stronger its ability to block radiation.

The density of amorphous metal is higher than that of gold, and if you encapsulate 200 standard fuel blocks, the thickness of the amorphous metal only needs to exceed 9 mm, which can completely block the nuclear radiation released by 200 standard fuel blocks.

Of course, in the cooling and maintenance stage after the completion of the task, boron-containing cooling water should be used to absorb the high-energy neutrons that slowly accumulate on the fission knife to prolong the service life of the fission knife.

In addition, after the fission knife is made from an amorphous metal, the fission knife loses the ability to deform freely.

Because there is a large amount of radiation inside the fission knife, this radiation can disturb the deformed magnetic field released by the maker. If it is rashly deformed, it is very likely that a leakage event will occur.

Ye Qing and Dianjing both agreed that as long as the appearance is cool, it doesn't matter if the fission knife changes and does not change.

At the same time, Electrocrystalline also intends to re-prepare a batch of fuel blocks.

The fuel blocks used in nuclear power plants are manufactured with moderating materials to slow down the fission rate.

The electrocrystallizer should be within the safety threshold to minimize the specific gravity of the moderated material. The fission velocity of the fuel block is close to the critical point, which greatly increases the fission velocity and fission temperature.

Theoretically, the fission knife can be heated up to 4000 degrees.

What is the concept of 4000 degrees?

Known as the hard-bone stainless steel in the metalworking industry, the melting point is only between 1400-1500.

The melting point of pure titanium is 1678 degrees, and the melting point of titanium alloys is even lower.

The high temperature of 4000 degrees does not seem to be as high as the 8000 degree plasma arc temperature after the energy storage boost.

But how big is the cutting diameter of the plasma arc?

The greater the cutting depth, the smaller the cutting diameter it has. When cutting 30 mm alloy, it cuts less than 1 mm in diameter.

The fission knife cuts 10 centimeters in diameter and is used to cut the hull of a ship with a melting point of only 1400 degrees, just as easily as cutting a piece of paper.

Thinking about the picture of the amorphous torpedo cutting the hull with a knife, and then cutting and cutting inside, Ye Qing felt very emotional.

"By the way, the name of the amorphous torpedo is not appropriate. ”

When he arrived at the nuclear plant, Ye Qing said to Dianjing: "If you want to exert the maximum power of the fission knife, you can't count on the shape of a fish." ”

"Uh-huh~ I'm going to design it as an amorphous robot that can transform multiple forms. ”

Dian Jing thought for a moment, but didn't come up with a suitable name, "Boss, what's that name?"
