In this world, there are many things that can cause headaches for the heads of the five permanent members of the United Nations and those advanced capitalist countries, such as population, environment, food, fresh water, mineral resources, garbage, etc., all of which can cause headaches for these leaders.

And among these things, there is one thing that can definitely be at the top, and that is nuclear waste!

Nuclear waste refers to radioactive waste that is no longer needed in the production and processing of nuclear fuel and in nuclear reactors. It also refers specifically to the spent fuel used in nuclear reactors, and after the reprocessing of usable nuclear materials such as plutonium-239, the remaining radioactive waste that is no longer needed.

On August 6, 1945, with the atomic bomb with a yield of about 13,000 tons and a total weight of 4.1 tons and called "Little Boy" that exploded in Hiroshima, and the atomic bomb with a yield of 20,000 tons and a total weight of 4.5 tons and named "Fat Man" that exploded in Nagasaki on August 6, the whole world knew that there was such a terrifying energy in the world.

At the end of World War II, the atomic bomb was only an uncontrollable nuclear fission reaction, but with the continuous development of science and technology, people gradually mastered the way to control this nuclear fission, which can produce huge amounts of energy. As a result, many controllable nuclear fission power generation devices have sprung up around the world, which are known as "nuclear power plants".

But while people enjoy the abundant energy provided by nuclear power plants, they also discover an unavoidable embarrassing fact, that is, the large amount of waste produced in the process of generating electricity from nuclear power plants is an extremely terrible existence.

These wastes all have terrible nuclear radiation, and those nuclear power plants produce radioactive waste liquids and wastes in the process of power generation, because the radioactivity of those wastes is not very strong, and they are classified as medium and low radioactive nuclear wastes, although they account for 99% of all nuclear wastes, but by digging trenches about 10-20 meters deep in the ground, and then building various anti-radiation engineering barriers, putting the sealed nuclear waste tanks into them and burying this treatment method, after a period of time, The radioactive material in these wastes will then decay into substances that are harmless to humans.

But in addition to the low- and medium-level radioactive waste, there is also about 1% of the high-level radioactive waste, which is the burned nuclear fuel that has been replaced from the reactor core of the nuclear power plant. Although the amount of these nuclear wastes is small, but extremely terrible, it contains about 200 to 300 kinds of radioactive nuclear elements, and the nuclear wastes produced after the fission of uranium-235, which is mainly used as nuclear fuel, are the most important ones that are extremely radioactive iodine-129, technetium-99, strontium-90, cesium-137, as well as neptunium, americium, curium and other transuranic elements!

The half-life of these highly radioactive nuclear wastes is generally very long, reaching tens of thousands of years or even hundreds of thousands of years, and once these things are leaked, they will cause irreversible disasters to the ecological environment!

What to do with this radioactive nuclear waste has become a headache for the heads of countries around the world that have nuclear power plants.

At present, the international treatment of those high-level nuclear wastes usually adopts two methods: sea and land, that is, the high-level nuclear wastes are cooled and stored dry, and then the metal canisters containing the nuclear waste are thrown into the seabed below 4,000 meters in the selected sea area, or buried deep in the nuclear waste disposal depot built in thick rock layers underground. Some countries such as the United States, Russia, Canada, and Australia generally use the land deep burial method due to their vast territory and vast wasteland, while France, the United Kingdom, Germany, and Japan will use marine treatment. Regardless of the method used, in order to ensure that nuclear waste is disposed of safely, countries are subject to international monitoring when disposing of nuclear waste.

By the end of 2011, there were 430 commercial nuclear power plants in 30 countries, supplying 13% of the world's electricity needs.

It is estimated that for every million kilowatts (1,000 megawatts) of nuclear power plants, about 30 tons of high-level radioactive nuclear waste can be produced a year, and the total installed capacity of nuclear power units currently in operation in the world is as high as 374,000 megawatts. More than 11,000 tons of high-level radioactive nuclear waste!

And more than 100 billion dollars are spent on the disposal of this nuclear waste every year!

And these nuclear wastes that make the heads of state feel pain in their brains, and the nuclear wastes that can't wait to send all these horrible things to Cybertron planet, are an inexhaustible treasure in Tang Feng's eyes!

In terms of the huge amount of food produced by the star core, I dare not say that I can eat all the nuclear waste produced within a year, but it is absolutely no problem to eat seventy or eighty percent of it, after all, this thing is more radioactive than natural radioactive elements!

Don't forget, in order to solve these nuclear wastes, all major countries in the world are spending huge sums of money to build permanent nuclear waste repositories, and a nuclear waste repository can easily cost billions or even tens of billions of dollars, which is also quite a heavy pressure!

What's more, each of these permanent nuclear waste repositories that have been built at a huge cost is also limited, and although this thing claims to be permanent, what is the actual service life? Who can guarantee that these repositories will be preserved according to their design age?

Don't forget, most of these repositories are in inaccessible areas, such as Yucca Mountain, where the United States plans to spend more than $90 billion to build a permanent repository for nuclear waste, deep in the Nevada desert, and Russia has placed the repository in Siberia. One of the characteristics of these repositories is that they are buried deep underground. But don't forget, Mother Earth's temper is sometimes not very good, a sneeze can cause an earthquake, and who knows if those disposal depots can resist the occasional eruption of Mother Earth's temper?

The permanent repositories built by these countries at great expense naturally do not say anything about their own country's nuclear waste storage, but if they are replaced by other countries to store nuclear waste, it will be expensive.

And Tang Feng now has a star core in his hand, the star core is the best tool for nuclear waste, there is no money consumption, no hidden danger of leakage, as long as you send the nuclear waste over, Lao Tzu will give you clean food!

It's just that whether this kind of nuclear waste can be absorbed by the star core depends on the situation of this experiment.

This is the main reason why Tang Feng came to St. Clement!

That's because the San Onofre nuclear power plant in San Clemen was once the largest source of electricity in Southern California, with a total installed capacity of 2,200 megawatts of three nuclear power units, enough to power 1.4 million homes!

Unfortunately, the plant's Unit 1 was decommissioned in 1992, Unit 2 was shut down in early 2012 for routine maintenance and technical upgrades, and Unit 3 was shut down on January 31, 2012 due to a leak in the internal steam generator pipes, and inspectors later found that hundreds of pipes were worn. In November 2011, an ammonia leak occurred at the plant, forcing employees to evacuate.

Now this closed nuclear power plant is just a place to store nuclear waste, and this is Tang Feng's destination this time!
