2011, a large amount of nuclear waste water has been produced, and now more than 1 million tons of water has been stored in tanks, and about 100000 tons will be added every year. The Japanese government's decision to discharge the nuclear waste water into the sea has aroused strong global opposition. However, we cannot solve the problem by blindly opposing it. To solve this problem, we must have effective methods. Is there any other safer and more economical solution to the nuclear waste water from the Fukushima nuclear power plant in
Japan besides being discharged into the sea.
Have! That is to solidify the nuclear waste water in the concrete and stack it safely. The ratio of water to cement
in the concrete is about 1:2. The water is solidified in the concrete by the cement as a gelling substance. That is to say, now more than 1 million tons of nuclear waste water from the Fukushima nuclear power plant can be made into millions of tons of concrete blocks with more than 2 million tons of cement and a proper amount of sand and stone. The nuclear waste water is combined with the cement in the concrete and is solidified in the concrete. It is not afraid of the wind, rain, sunshine and earthquake bombing. Millions of tons of concrete are stored in an area of less than 1 square kilometer, while hundreds of square kilometers around the Fukushima nuclear power plant have become a no-man's land. The main radioactive substances in
nuclear waste water are tritium and cesium 137. The half-life of tritium is about 13 years, and that of cesium 137 is about 30 years. That is to say, after 300 years of storage, the radioactivity of tritium is only about 1/8,000,000 of the original, and the radioactivity of cesium 137 is only about 1/1,000 of the original. When the radioactivity of these concrete blocks decays below the safety limit, these concrete blocks can be used to build breakwaters. In order to prevent tsunamis, Japan needs to build breakwaters in many places along the Pacific coast. Concrete is so durable that it can maintain its strength for hundreds of years. The nuclear waste water has been solidified in the concrete and can not come out. The current price of
cement is 300 to 500 yuan per ton, and the purchase cost of more than 2 million tons of cement is about 1 billion yuan; sand and stone are very cheap and not worth mentioning. By comparison, the damage caused by the Fukushima nuclear power plant is as high as trillion yuan. This money is really not a lot of money. What do
you think of the solution I proposed?
