Bismarck

"So... Lily, what topic are you researching now?"

Changing the question, Lütjens thought that if this were the case, his daughter should be able to tell the answer, right?

"Well, the topic that Professor Heisenberg assigned to my research group is the power of nuclear energy. He said that we should use the energy of nuclear reactions as a driving force..."

nuclear power?

Lütjens kept a straight face, but he was feeling somewhat dissatisfied in his heart.

After all, he had already investigated the delays and slackening of work by the people at the Kaiser Wilhelm Institute of Physics. He was even rejected by Planck, the great master, when he first arrived at the Kaiser Wilhelm Institute.

This "nuclear power"... It feels like the progress of the Kaiser Wilhelm Institute for Physics is still not even started.

but……

"Eh? A nuclear reactor?"

Before Lütjens realized how powerful this thing was, Bismarck's ears had already stood up instantly.

After all, she had heard a lot about nuclear power plants, nuclear-powered warships and so on in her "previous life"!

Although many people also say that nuclear reactors are dangerous, polluting, radioactive, and even many people are causing trouble everywhere, Lily studied nuclear physics, and she had already inquired about it. As long as safety measures are in place for things like nuclear radiation and operating specifications are followed to ensure that no accidents occur, the actual threat is far from as terrible as people say!

In fact, in this era, some people even think that radiation may be good for the human body. She had argued with Lily several times about this. In the end, she forced Lily to promise to pay attention to safety, be careful of radiation, and not violate regulations...

Although she didn't know whether this promise was valid, she still had to remind Lily. However, she was a little interested in the nuclear power.

If my sisters and I could have nuclear power... that would mean unlimited endurance!

Why was the last breakout so difficult? Wasn’t it because the sisters didn’t have enough endurance?

If there is an infinite endurance nuclear power, I am afraid it is not...

The Persian cat laughed silly in an instant.

Hehehe, she was thinking whether she should install a “solar furnace” for herself after this research comes out?

Seeing Bismarck beside them suddenly startled and then immediately became dazed with a silly smile on his face, Lily and the captain were a little stunned.

"Dad, what's wrong with Bismarck?" Lily, with a confused look on her face, suddenly felt that it would be better if her father did not get infected.

After all, white stuff is said to be contagious~

"Well, this girl must have come up with something new..."

The captain had seen his ship cat act silly several times, and although he was no longer surprised by it, Lütjens always felt that this cat was a bit embarrassing, so he couldn't help but stroke his forehead and sigh.

He stretched out his other hand and pushed Bismarck, who was looking at the cat in front of him stupidly: "Bismarck, Bismarck?"

"Eh? Captain?"

Looking at the confused Bismarck who had just been “resurrected” from his wandering state, Lütjens, who had already decided to give up treatment but was still curious about his own ship cat’s endless imagination, said calmly: “Bismarck, have you thought of something else?”

"Yes! I was thinking, nuclear energy has such great power. If it is used as a power source, we can have almost unlimited endurance!" Bismarck said excitedly.

"Eh? Bismarck, you also know about nuclear power?!"

Seeing such a Persian cat, Lily was a little stunned. Although she knew that her father was the director of scientific research, she did not expect that Bismarck also knew about nuclear power, and seemed to know a lot about it.

and……

Not to mention Liliana, even Lütjens was stunned when he heard the words "unlimited endurance".

"Bismarck, what did you just say? Infinite endurance?!"

Lütjens was stunned for a while, but after he reacted, his face showed a look of disbelief and joy.

Having served in the navy for so many years, Lütjens knew very well that under conventional power, no matter how hard one tries, there is a limit to the endurance of a warship!

If nuclear power can have unlimited endurance, that would be a great thing! Wasn’t it because of insufficient endurance that we fought so hard in the previous breakout battle? ?

Even if we can't actually achieve unlimited endurance, as long as we can refuel once every few months, it will be much better than it is now!

Thinking of this, Lütjens immediately turned around and looked at his daughter: "Lily, can nuclear power really have a long endurance?"

"Infinite endurance... that only exists in theory. But if the nuclear power is as expected, there will be no problem in replacing the core every few years or even more than ten years!" Lily thought about it and said with certainty.

"How...how many years?!" Lütjens was really shocked this time!

It takes several years, or even ten years, to replace nuclear fuel - doesn't this mean that you can go wherever you want in the world's four oceans? !

"Is this thing really that powerful?!" The admiral, who usually showed a blank expression, was now dumbfounded.

"Yes, Dad... But, I have no idea how to design this thing right now..."

Looking at her father's eyes that were comparable to Columbus's discovery of the New World, Lily smiled bitterly.

but……

"I have some idea of ​​how to design this nuclear power thing!"

A blonde Persian cat suddenly came between the father and daughter.

"You? You knew?!"*2, the captain and Lily said in unison.

"Of course we know. Isn't it just an armored box with a lead shielding layer, with a nuclear reactor inside? The reactor uses the heat of the nuclear fuel to drive water or some other liquid to transfer heat, instead of the boiler to heat the water vapor, and finally draws the water vapor into the steam turbine, so there is energy output!"

Speaking of this, Miss Big Xiao tilted her neck back, put her hands on her hips, and looked very righteous.

"How did you know that?!" Lily lost her composure after hearing what Bismarck said made so much sense. Her scientific spirit took over. She was stubborn and strong-willed and didn't care that she was having lunch in front of her father. She threw herself on the Persian cat's shoulders and said, "Anything else?! Tell me quickly - wait, let me take a note!"

As he spoke, he quickly took out a pen and notebook from his bag, and then stared at Bismarck, who looked mysteriously confident.

As for whether this was a restaurant, or whether the confused man with his jaw dropped to the ground and forgot to pick it up was her father, Lily was too lazy to care.

"No problem. Let me tell you, although this thing is not difficult, there are still some technical details to consider, especially safety. For example, the outlet of the heated working fluid should be placed on the top of the reactor to achieve natural circulation, and the control mechanism of the control rod should also be on the top. In case of any accident, the switch can be released to shut down directly..."

"Wait, you said shut down? This thing is not the boiler on your body! When the nuclear reactor is at low output, if the energy cannot be transferred out, it will be high temperature and high pressure!"

As Lily listened, she seemed to understand something. She wrote it down in her notebook and asked questions.

"Really? Well, I don't know, but I just told you to consider safety issues when designing the reactor~"

Although he only had experience in using boilers, Bismarck would never say that he had seen many nuclear accidents in his later life, and they were rumored to be very terrifying!

Besides, this is something she wants herself, so how can she not pay attention to her own safety?

but……

"stop!"

Seeing that the two girls in front of him were about to discuss technical issues directly in the box, Lütjens felt uneasy.

This is a restaurant outside, not a safe and secure office! Besides, it's a rare family reunion, and they were supposed to have lunch, but now they haven't eaten a single bite, and they are planning to do technical research and development work here? !

"This is a restaurant! Why are you talking about technical issues here? Let's eat! After we finish eating, I'll talk to you guys later!!"

With the power of a head of the family, he slammed the table and yelled at the two precious girls in front of him in an unpleasant manner.

But what responded to him were the two girls who were forced to shut up, two pairs of eyes rolled at the same time, and a resentful "Tsk~!"

Watching this scene, Lütjens, the dignified Golden Knight and admiral of the navy, suddenly felt a little hurt in his heart...

------The dividing line that turns depression into food intake------

Ever since she heard the idea of ​​nuclear reactor from Bismarck, Lily, who was obsessed with the idea, had just finished lunch and almost dragged Bismarck and her father back to the office, and then pestered Bismarck to start thinking about the idea.

Although it is still just an idea rather than a strict design, at least in this era, having a definite direction can help us avoid many detours.

Besides, Lily had been with Heisenberg and his gang for several years, so she had gained some experience and knowledge. Although she could only make some conventional calculations, she could guess the basic principles. And the two men, Lütjens and Lindemann, were finally "fortunate" to hear some technical information firsthand.

Moreover, it was the Commander’s daughter who was in charge of explaining, and the Secretary Cat who was in charge of imagining!

However, after some discussion, questions came up one after another:

First of all, in order to achieve a power no less than that of the current Bismarck main engine system without increasing the volume, the concentration of U235 in the reactor must reach more than 90% - as far as Bismarck knew, this concentration of U235 could be used directly to grow mushrooms!

Although Bismarck knew clearly from both Lily's knowledge and knowledge from later generations that there was a critical mass in mushroom cultivation, and Bismarck remembered seeing somewhere that it was about 5 kilograms - it was said that after the war, the Americans divided U235 into small pieces of varying volumes and masses, and experimented with manual compression one by one - but the specific mass of this thing was still unclear at this time when nuclear energy had just emerged!

On the other hand, how to extract such a high concentration of U235 is also a problem in this era.

Although in later news, a small East Asian country, which was not prevented from developing its own mushroom cultivation industry to "protect its security" even when it was blocked by the whole world, relied on 2000 centrifuges that were considered to be of inferior technology to grow small mushrooms into large mushrooms in ten years, but Germany now has no ten years to wait - and according to Lily, the speed of the centrifuge array should reach at least tens of thousands of revolutions, and it is conceivable that it has extremely strict radiation and leakage protection requirements. Although it is not impossible to produce it now, it seems that none of the German companies are willing to do these things.

In addition, even if some ideas such as "natural circulation through heating and rising, and the control rods can be forcibly inserted by gravity by disconnecting the buckles in an emergency, and there are shielding layers, armored steel and emergency cooling systems to prevent reactor meltdown" are confirmed in principle, the specific design of the reactor is not something that Lily, a little researcher, and a Persian cat can solve with their patchwork imagination from the future.

The pressurized water reactor can only heat the steam in the secondary circuit to about 280 degrees. If you want higher temperature and pressure, you either need to add a few more auxiliary boilers or use a graphite reactor. However, according to Lily, the purity requirement for graphite used in reactors is one part per billion! The purity of graphite products in the German nuclear industry is not up to standard.

Moreover, in addition to this, the by-products of graphite include the highly toxic and highly radioactive Pu239!

Although this thing can also be used as nuclear fuel, but when Persian Cat heard that it was highly toxic and radioactive, he began to worry about the pollution problem. Lütjens and Lindemann were puzzled: Pollution? What the hell?

Well, due to the limitations of the times, Bismarck had to explain the concept of radioactive nuclear pollution, which had never appeared at that moment. Even Lily only understood a little bit...

"Is nuclear pollution really that scary? I feel fine in the research institute. And there was an explosion at Professor Heisenberg's nuclear research institute at the end of June. We tested it afterwards and it didn't seem to have any impact."

Bismarck was a little speechless after hearing what Lily said. But after all, she only heard this idea in the future, and she couldn't say anything specific.

I can only continue to remind Lily to pay attention to her personal safety...

Fortunately, Lily took a leave of absence until the next day, so I could continue to instill some ideas in her.

After all, radiation carries risks, so players need to be cautious.

We discussed it with great interest from the time we finished lunch until the lights came on. However...

"In that case, this nuclear power system sounds very promising!" Although he only understood a little bit of it, it did not stop Lütjens from looking excited.

After all, if this thing is developed, wouldn’t the few ship girls on my side also benefit from it?

However, when it comes to this question, Lily, who was originally very excited, suddenly drooped down, as if a bucket of cold water was poured on her head:

"Well, Dad, researching these ideas can speed up the development process, but..."

Shaking her head, Lily thought of her immediate superior, Werner, the "reactionary academic authority" Heisenberg, the great man! Even other master-level physicists were not allowed to change his design!

Although many people knew that the design efficiency of the "flat stacking" scheme that Heisenberg insisted on was far inferior to the honeycomb staggered fuel rod design of the Dibner team, the fact was that Heisenberg did not want to change his design at all! He would not listen to anyone's advice!

"Is it Heisenberg and his gang? What exactly are they thinking, Lily, can you tell me?"

Lütjens had been attacked by these scientists as soon as he took office, and then he asked Lindemann to investigate for two months. He knew that these people were deliberately causing trouble. However, Lütjens wanted to find out why these people were causing trouble, and whether there was anyone suspected of being a traitor.

Although these people may not support Hitler, their betrayal during wartime has far exceeded the bottom line!

Besides, this was the main purpose of calling Lily back!

but……

When Lily thought of these things, her mood suddenly became even more depressed.

Although Heisenberg actually cared a lot about fame and fortune, he did this purely to maintain his academic status. However, she could actually vaguely guess that her father asked this because he had some opinion about these people...

If that's the case, will there be any consequences if I say this...?

Having spent a few years in the Institute of Physics, I have some feelings for it! And I don’t want to affect the normal order of the entire Institute of Physics because of my own reasons…

A complex look that could be described as being in a dilemma gradually emerged in Lily's eyes.

"Lily, don't be nervous. The captain just thinks that if Heisenberg's place is not suitable, he might as well arrange for you to be assigned to another institute."

Bismarck had thought from the beginning that Lily might have some concerns, and had long been worried about this, so he quickly winked at his captain, then grabbed Lily and began to perform the scheming girl's show.

However, what was more surprising was that Lily, who was obviously struggling, remained silent for a long time, and finally shook her head slowly, and even her words were obviously insincere:

"No, nothing happened. Actually, Professor Heisenberg was just a little overbearing. Otherwise, it's fine..."

"This……"

Lütjens was a little stunned, and even a little angry.

I'm just investigating! Heisenberg is unreliable. Does he really think he can't find another research group?

As far as he knew, the Navy had at least several nuclear scientists in those "other research groups" who were also studying the topic of nuclear power!

What’s more, the most heartbreaking thing is that I have raised my daughter to this age, but now her elbows are bent outwards!

However, Bismarck saw this scene and thought to himself, "Oh no!" While the captain was still not angry, the thoughtful and scheming cat winked at his captain several times:

"Captain, don't ask first, let me ask!"

Looking at the look in his secretary's eyes, and thinking that his secretary Cat and Lily were of the same age, both girls, and had common topics, Lütjens might be able to figure out something, so he pondered for a moment and nodded gloomily.

Chapter 763: Pressure and Conspiracy

Stubborn but sensitive Lily is caught in an inexplicable tangle between her father and her workplace.

Some family conversations that could not continue ended with a somewhat boring meal.
