Why does the temperature inside the Fukushima nuclear power plant in Japan still rise rapidly after

Because the nuclear fuel rods release a lot of heat when they are used, the water is constantly cooled repeatedly, but because the cooling system is destroyed, the heat generated by the fuel rods cannot be exported, and the water outside begins to evaporate, and when the water dries, it begins to melt the zirconium jacket (which wraps the fuel rods), so the leakage occurs

I suspect that the nuclear reaction continues.

It's so simple, just look at why the sun heats up.

The nuclear power plant has been shut down at **, but the temperature is still high because the fuel rods still decay to generate heat. No heat is generated until its natural decay is complete, and this process must be kept cooled or it will quickly rise to 3,000 degrees Celsius.

Those who enter the manual shutdown of the nuclear power plant and those who remain behind are like sending them to death: each person is exposed to radiation of 100-250 millisieverts, and long-term exposure to radioactive fallout is very risky, and a person who is exposed to more than 100 millisieverts (MSV) of radiation in a year is prone to cancer.

Fukushima nuclear accident, radioactive material leakage accident. The Fukushima nuclear accident, the Fukushima Daiichi Nuclear Power Plant and the Fukushima Daiichi Nuclear Power Plant were severely affected by the Fukushima Daiichi Nuclear Power Plant and the Fukushima Daiichi Nuclear Power Plant in the Northeast Pacific region of Japan on March 11, 2011. The Fukushima Nuclear Power Plant is located at 37 degrees 25 minutes 14 seconds north latitude and 141 degrees 2 minutes east longitude, and is located in the Fukushima Industrial Zone of Japan.

It was the largest active nuclear power plant in the world at the time, consisting of the Fukushima Daiichi Nuclear Power Plant and the Fukushima Daiichi Nuclear Power Plant, with a total of 10 units (6 units at the first station and 4 units at the second station), all of which are boiling water reactors. On March 12, 2011, Japan's Ministry of Economy, Trade and Industry's Nuclear Safety and Security Agency announced that radioactive materials from the Fukushima Daiichi Nuclear Power Plant had leaked to the outside due to the impact of **. On April 12, 2011, Japan's Nuclear and Industrial Safety Agency (NISA) classified the Fukushima nuclear accident as a maximum nuclear accident level of 7 (mega accident), which is the same level as the Chernobyl nuclear accident.

On April 13, 2021, Japan** officially decided to discharge millions of tons of nuclear-contaminated water from the Fukushima Daiichi Nuclear Power Plant into the sea.

Now it is necessary to use water to cool down because after a radiation leak, in order to control the temperature of the reactor, it is necessary to continuously inject water to cool down the water, although the nuclear wastewater.

It can be used for circulating cooling, but because the Fukushima nuclear power plant is close to the sea and the terrain is low, the underground water and rainwater continue to seep in, so the nuclear wastewater is becoming more and more abundant. As of March 2021, 1.25 million tonnes of nuclear wastewater had been stored, with 140 tonnes added every day.

Follow-up to the Fuchashan Island Nuclear Power Plant:

On March 10, 2021, Japan's Nuclear Power Commission released a report that Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station.

New contamination sites have been discovered inside, much more severe than expected. In addition, units 1 and 3 nuclear reactors.

Some of the gas discharged from the pressure vessel has a backflow, which may cause it again**.

On March 26, inside the plant, crews found signs of a possible nuclear leak.

On April 9, Japan basically decided to discharge nuclear sewage from the Fukushima Daiichi nuclear power plant into the sea. On April 13, Japan** held a relevant cabinet meeting to formally decide to discharge millions of tons of nuclear sewage from the Fukushima Daiichi nuclear power plant into the sea after filtering and dilution, and the discharge will begin in about two years.

When an accident occurred in Chernobyl in the Soviet Union, death squads were used to go in and shut down equipment for rescue, and a large amount of sand and other materials were used to airdrop and absorb neutrons. On the other hand, in Japan, on the one hand, they are worried about money, on the other hand, they are afraid of death, and on the other hand, they are lucky.

It is because the nuclear power plant cannot be stopped now, the "stop control rods" are melted, and the fuel rods are dry burned. The cooling water pressure is too high, and the degassing causes hydrogen**. Manual operation cannot be carried out. Several people have died

The Japanese nuclear power plant went into the manual shutdown of the nuclear power plant and the remaining ones were like sending them to death:

Every person is exposed to radiation of 100-250 millisieverts, and long-term exposure to radioactive fallout is associated with a high risk of cancer, and a person exposed to more than 100 millisieverts (MSV) of radiation in a year is prone to cancer.

The Fukushima nuclear power plant is one of the worst nuclear disasters of the 21st century, which occurred in March 2011 and was caused by a tsunami caused by the project. The disaster had a huge impact on the world and caused a global discussion about safety as well as nuclear energy. There are many people who have doubts about whether the reactors at the nuclear power plant can be stopped after the accident.

After the accident, according to relevant reports, the reactors at the Fukushima nuclear power plant were not stopped immediately. This is because the heat emitted by the fuel rods in the reactor during the nuclear reaction needs to be dissipated by water and the fuel rods are kept cool to maintain the stability of the reaction. Therefore, even if a natural disaster interrupts the energy of a nuclear power plant, the reactor can still last for a certain period of time.

However, due to the power outage caused by the tsunami and difficult water supply conditions, the reactor lost its cooling capacity within a few hours, resulting in the leakage of radioactive materials and the continued occurrence and heating of nuclear reactions. This situation is dangerous in all nuclear reactors and requires immediate measures to avoid the aggravation of the accident. In the Fukushima accident, the instantaneous collapse and melting of the fuel rods led to severe damage to the reactor's durable equipment, which ultimately led to a catastrophic accident.

Thus, theoretically, a nuclear reactor has the ability to maintain continuity on a temporary basis in the event of difficult water supply conditions and power outages. However, under the influence of specific natural disasters and environmental factors, nuclear reactions can still occur uncontrollably and eventually lead to catastrophic accidents. It is important to note that nuclear reactors are only one of the extremely safe technologies used by humans to stop cars, so it takes a lot of time and money to ensure their safety in case of catastrophic accidents.

In conclusion, the reactors at the Fukushima nuclear power plant accident did not stop immediately. Experts in science and engineering are now looking for smarter and safer solutions for nuclear reactors. At the same time, we must also pay attention to the security of the global environment and the sustainability of energy development. <>

All the operations of Japan's Fukushima nuclear power plant have been attracting the attention of people all over the world since their first day, especially Japan's decision to discharge the nuclear wastewater produced in Fukushima into the ocean has caused dissatisfaction among people all over the world. In addition to such a despicable move, Fukushima was shut down on September 16 by the purification unit inside the ** nuclear power plant. So what is the reason why this device stopped working?

At present, the Japanese side said that it is still conducting an urgent investigation into the device, so we do not know the reason why the device stopped operating at this time. Let's take a look at the specifics of the matter.

This incident happened on September 16, a Japanese authority** said that there was an accident at the Fukushima Daiichi Nuclear Power Plant - the underground purification unit suddenly stopped operating, and such news caused a lot of attention. Because this underground purification device is used to purify nuclear wastewater, if this purification device stops operating, then the nuclear wastewater will enter the sea without evolution, and the relevant personnel**, if the nuclear wastewater is not discharged into the sea and placed in the oil storage tank, then the Fukushima oil storage tank will reach saturation within 3 days. In the face of such news, many netizens have expressed their disbelief, and many people think that Japan has not opened a purification device at all, and the statement at this time is questionable.

I think Japan** is really a very irresponsible**, without considering the environment of other countries such as the Wax made the decision to discharge nuclear wastewater into the sea, and then there was such an accident, and at the same time, the scum and slippery did not understand the cause of such an accident, it was simply a child's play, really thought that something happened and bowed to the end of the matter? When the earth's environment is contaminated to a certain extent by nuclear weapons, the first group to enjoy the consequences will inevitably be the Japanese. I feel that we, as Japan's neighbors, have really suffered from this.

It was stopped because there was a problem, and the details were not announced in the process of investigation.

The reason for the shutdown is not particularly clear at this time, but it should be an investigation of the equipment and maintenance to determine the specific situation inside.

The main reason for stopping the operation of the fiber section should be that it is being repaired and damaged, and it is also because it seems to have been used for too long, and then it has not been repaired, so it will stop running.

Summary. Hello dear for 36 years The Fukushima nuclear power plant consists of two nuclear reactors, the first reactor was built in 1971 and began commercial operation in 1975, and the second reactor was built in 1973 and started commercial operation in 1982. Therefore, the Fukushima nuclear power plant will be in operation for 36 years.

After the accident at the island nuclear power plant, Japan** decided to gradually reduce or stop using nuclear energy in order to reduce the risk of nuclear accidents. At present, the Fukushima nuclear power plant has ceased operation and is being dismantled and cleaned up. The Fukushima nuclear power plant accident is one of the most serious nuclear accidents in the world, reminding us that we must attach great importance to nuclear energy safety and continuously strengthen nuclear safety management and supervision.

The Fukushima nuclear power plant accident occurred on March 11, 2011, when a tsunami caused several reactors at the plant to lose their cooling systems, resulting in a nuclear leak. The accident caused the leakage of a large amount of radioactive material, which had a great impact on the surrounding environment and human health, and was called one of the biggest disasters of the 21st century. Currently, the dismantling and clean-up of the Fukushima nuclear power plant is still underway and is expected to take decades or more.

At the same time, the Fukushima nuclear power plant accident has also aroused great concern about nuclear energy safety around the world, and countries** and relevant institutions are taking measures to improve the level of nuclear energy safety. <>

I believe that the shutdown of the purification plant at the Fukushima Daiichi Nuclear Power Plant will have a relatively large impact, and it will have a bad impact on the environment of Zhou Youzi and the ecological environment.

This incident is particularly dangerous, I think this matter should be taken seriously, and the purification device should not be stopped, otherwise it will bring a lot of safety hazards to the world.

This kind of crude practice is very inappropriate and immoral, and it is more unrespectful of nuclear pollution, and the impact on human beings and the ecological environment is very large, and if it is stopped, then nuclear pollution will become more and more severe.
