Back in the room, Han Feng set an alarm for eight in the morning. In such a dark environment, Han Feng felt a little uneasy in his heart.

Sitting on the bed, Han Feng contacted Simon: "Simon, have you discovered anything?"

"Report to the Korean team, nothing has been discovered yet."

"Okay... let everyone work hard tonight and increase the number of people on duty." Han Feng said, feeling uneasy.

"Okay Captain Han, you can rest, I'm here." Listening to Simon's confident voice, the last trace of uneasiness in Han Feng's heart disappeared.

Yes, with Simon and more than a hundred Red Police soldiers standing guard, what's the problem? After laughing at himself, Han Feng lay on the bed and slowly fell asleep...

"Dingle bell! Dingle bell!" At eight o'clock in the morning, a rapid sound of the alarm woke Han Feng up.

Rubbing his sleepy eyes, Han Feng reluctantly got up and turned off the alarm clock...

While washing, Han Feng contacted Luna and Simon and asked, "Did anything happen last night?"

"Reporting to the Korean team, everything was normal last night and there were no problems." The first person to speak was Simon, who had been on guard for the entire night shift.

"Thank you for your hard work, Simon. If you have nothing to do during the day, let the soldiers take turns to rest. Cancel the mission of killing zombies today." Han Feng also knew that all the red police soldiers did not rest last night. In order to keep them strong, Han Feng

Feng decided not to "make money" today.

"Okay, Team Korea, I will make arrangements."

"What about you? Luna." After Simon replied, Han Feng asked Luna again.

"Reporting to the Korean team, there was a small-scale conflict between the survivors and the soldiers last night, and it has now subsided."

"Conflict?! What conflict?!"

"Because of the panic caused by the power outage."

"...I understand, call the engineer over. By the way, let Wayne prepare the armored vehicle, and remember to bring all the equipment! Bring four more one-star American soldiers, Simon will follow, and we will set off in a while.

"Hearing that the survivors started to panic, Han Feng felt nervous.

At this time, the most urgent thing right now is to restore power.

After washing up, the engineer just arrived.

"Can you confirm the location of the power plant now?" Han Feng asked as soon as he saw the engineer.

"I can confirm, Team Han, I found the city circuit plan yesterday."

"Okay! Let's go now! Luna, mark the location of the power plant to Wayne."

"Okay Team Han, Wayne is already downstairs."

"Let's go." Hearing that the car had arrived downstairs, Han Feng called to the engineer and went downstairs together.

Along the way, Han Feng told Wayne to try to avoid zombies. Although he brought Simon and five one-star American soldiers with him on this trip, the number was still far from enough. Although this mission was only to repair the power station, it was not an outing.

Kill zombies, but be careful on the road.

After more than half an hour of "cautious" driving, Han Feng and his party finally arrived at the power plant.

As soon as he got off the car, Han Feng looked at the door of the power plant, which remained motionless for a long time...

"What's wrong, Captain Han? Did you find something?" Seeing Han Feng's strange behavior, Simon walked back and asked.

"Nuclear... Nuclear power plant? What the hell is this a nuclear power plant?!!!" Han Feng pointed at the three words on the power plant door with a trembling hand, and said

Said fearfully.

"Um...right? This is the nuclear power plant?" At this time, the engineer also came back.

"Oh my god...the power supply to the prison is actually a nuclear power plant?!"

"..."

"..."

Looking at the panicked Han Feng, Simon and the engineer didn't know what to say...

"Let's go, Team Han. It's not as scary as you think, it's just a nuclear power plant." Seeing that Han Feng still didn't move, the engineer pulled Han Feng and said.

A few minutes later, eight people arrived in front of a building.

"We're here. Wait for me for a while." After the engineer said this, Simon continued: "Okay, the four of you and the engineer will go in together. If there are zombies, shoot and kill them immediately."

After the engineer and four American soldiers entered, only Han Feng, Simon and Wayne were there. It was only then that Han Feng came to his senses...

Along the way, Han Feng's brain was in a daze. He thought about the scene of a nuclear power plant explosion countless times...

"Da da!" Suddenly, a burst of gunfire rang out in the building, but it only lasted for a few seconds and then stopped. It seemed that the engineers and the others had encountered zombies in the building.

Smoking a cigarette, Han Feng squatted on the ground. He thought to himself, why are you following me? This is a nuclear power plant! What if it explodes? No one has been looking after the nuclear power plant for so long. There is no guarantee that there will be no problem this time. And it is already close to the power outage.

After a night's separation...how long can I hold on?

"Team Han? Team Han?" Just as Han Feng was immersed in his inner world, the engineer's voice suddenly sounded in his ears.

"Ah? What's wrong?! Is the nuclear power plant going to explode?!"

"Pfft..." Seeing Han Feng's nervous look, the engineer couldn't help laughing.

After laughing a few times, the engineer said: "Team Han, this is a nuclear power plant. It will last for a period of time even if no one is watching over it. It's not a firecracker. How can it explode at will?"

After hearing what the engineer said, Han Feng smiled awkwardly. Recalling his previous embarrassment, his face felt hot... Han Feng had watched a movie "Chernobyl" before, which told the story of a leak in a nuclear power plant.

It is very serious. Thinking of the nuclear power plant that has not been maintained for so long, Han Feng, as an ordinary citizen, is worried about leaks and explosions.

Looking at the relaxed engineer, Han Feng asked: "Well... has the power been restored? What's going on inside?"

"Reporting to the Korean team, the situation inside is not optimistic..." When he said this, the engineer's face gradually became serious.

"What do you mean by not being optimistic? Could it be true... that it will explode?!" At this moment, Han Feng's heart started to relax again.

"Explosion... it won't happen now. The situation inside is like this. First of all, nuclear power plants are different from reactors. Some special reactors can be unmanned for a month without any problem. This is a pool reactor."

"Isn't this pretty good? It's fine for one month. Now it's been left unattended for less than half a month, and the power outage has been less than half a day. Then you go to repair it?!" After listening to the engineer's introduction, Han Feng became serious.

He breathed a sigh of relief and urged the engineer to repair it.

"But the problem is that the nuclear power plant inside is not a pool-reactor structure... but a shell structure..."

"Huh? Shell structure? Does it matter?" Han Feng asked patiently about the terms he didn't understand.

"There is a big concern

System, shell structure, requires a pump unit to continuously pump the coolant (light water in most cases) into the pressure shell container where the reactor core is located. This process requires electricity, which is what a power outage can bring.

The biggest threat—lack of cold.”

After a pause, the engineer continued: "Because loss of cooling is the most terrifying thing, nuclear power plants now have many countermeasures. If an external power outage occurs in a nuclear power plant, the reactor will not stop completely immediately. Even second-generation reactors have

It has its own diesel generator and UPS power supply. So when there is an external power outage, the UPS power supply will be connected first, and then the diesel generator will start."

"Then what?!"

"I just checked the diesel generator. Although it started automatically and brought temporary power to the power plant... but because there was no personnel to monitor it, the diesel generator ran out of fuel and the reactor was still in a power outage."

"What will be the final result...?" At this point, the air began to solidify little by little. For a few moments, Han Feng actually felt like he was suffocating.

"If the external power supply never recovers, eventually heat will slowly accumulate and the coolant will gradually heat up. At this time, loss of cooling will still occur. After loss of cooling, excessive pressure will occur in the pressure shell container. At this time, it is necessary

Release the pressure, but the release of pressure means accelerated loss of coolant, which will lead to a vicious cycle."

After taking a deep breath, the engineer continued: "No matter what protection measures are taken, they cannot stop the heat slowly released by the fuel rods in the reactor. The huge heat will cause the zirconium alloy and water to react to generate a large amount of hydrogen. Later, there will be problems due to the accumulation of hydrogen.

Too much, and the pressure is too high, leading to an explosion. In the end, the huge heat will melt the entire fuel rod, causing the fuel blocks in the zirconium alloy to fall out. This is the so-called core meltdown, which is the most terrifying accident in a nuclear power plant."

"...Can the explosion be avoided?" Han Feng's "calm" words contained a hint of trembling.

"A meltdown is not an explosion... but it is more terrifying than an explosion. Nuclear radiation will contaminate every inch of land here without restraint. It will take hundreds or thousands of years to recover."

"Then how can we avoid the meltdown you mentioned?"

"I'm sorry, Captain Han...I...I can't help it. The coldness has already started..." After saying that, the engineer slowly lowered his head...

"The time until the nuclear power plant reactor melts down is about 48 hours from now, and it won't happen within at least 36 hours. I'm sure of this!" Suddenly, the engineer raised his head and said firmly.

This sentence gave Han Feng a shot in the arm! Then he said: "It means we have less than two days to evacuate?!"

"right."

"Okay! Go back quickly! Go back and tell everyone to evacuate!" After saying that, Han Feng walked towards the gate of the nuclear power plant. On the way, Han Feng also asked the engineer: "How far do we need to evacuate? The radius of this leaked nuclear radiation is

How far?"

"Strictly speaking, nuclear radiation has no radius. Because after the radioactive material rushes into the atmosphere, it will spread rapidly with wind and other climatic conditions. However, since the explosion site is the source of the radiation, the radiation site will be the most severely affected.

.”

After thinking for a moment, the engineer continued: "According to my estimation, if a nuclear power plant leaks like this... within thirty kilometers is an extremely dangerous zone! One hundred kilometers is a buffer zone. Although there is danger at this distance, the danger will not be too serious.
