How to deal with the nuclear sewage produced by the leakage of Fukushima nuclear power station in Japan has always been a major problem. According to Japan's daily news, Japan's new government has decided to reduce the concentration of radioactive substances stored in the first nuclear power plant in Fukushima, Tokyo Electric Power Company, and will confirm the decision at the relevant cabinet meeting within this month. The Japanese government's plan to discharge the Fukushima nuclear waste water into the Pacific Ocean has aroused concerns not only from neighboring countries, but also from the whole world. Greenpeace International warned on October 23 that the contaminated water discharged from the Fukushima nuclear reactor into the sea contains radioactive substances and may damage human DNA.

Nuclear pollution has great consequences, wide range and long time. Neighboring countries have also expressed serious concern and hope that the Japanese government will make prudent decisions on the basis of full consultation with neighboring countries. As early as June, the relevant special rapporteurs of the United Nations concerned about the disposal of hazardous substances made a statement, urging the Japanese government not to ignore its obligations on nuclear waste disposal, and not to take advantage of the epidemic situation and force nuclear waste water into the sea without international consultation. Moreover, fishermen and people near Fukushima in Japan also strongly oppose the Japanese government's discharge of nuclear contaminated water into the Pacific Ocean.

Of course, the opposition of Japan, neighboring countries and the United Nations is justified and scientific. Moreover, no one can guarantee that water containing radioactive nuclear substances will have any impact on human health and life, as well as evolution. But at least it can be judged that nuclear contaminated water may lead to gene mutation, which has a negative impact on marine life and marine environment, and the impact can last for thousands of years.

Since the Fukushima nuclear power plant accident in Japan on March 11, 2011, nuclear pollution has inevitably affected the local land and sea. Researchers have observed some plant and animal abnormalities caused by gene mutation. For example, only one dorsal fin was found recently, while the normal shark had two dorsal fins. Moreover, nuclear polluted water does not only affect neighboring countries and sea areas, but also can affect more distant countries through ocean currents.

Due to the global warning and opposition, Japan has to postpone the decision on whether to discharge the nuclear polluted water into the sea. At a press conference on October 23, Hiroshi Fukuyama, Japan's minister of economy and industry, said the government had no plans to make a decision on how to deal with more than 1.2 million tons of nuclear sewage. "We can't announce a specific time for" how to treat nuclear sewage "at present.

The delay in making a decision does not mean that the pollution incident at the Fukushima nuclear power plant has been solved, it only delays the crisis. But this nuclear pollution crisis must be solved sooner or later. Obviously, from the perspective of nuclear pollution and other catastrophic accidents in the history of mankind, it is no longer applicable that "people should tie the bell to solve the problem", but it needs the joint efforts of many countries in the world. Otherwise, if the Fukushima nuclear sewage is discharged into the sea, everyone may suffer from it. Japan alone is unable to bear the responsibility for the aftermath of Fukushima nuclear pollution.

The aftermath of the Fukushima nuclear pollution incident may need to learn from and learn from the aftermath of the Chernobyl accident under the auspices of the United Nations. On April 26, 1986, an explosion occurred at reactor 4 of the Chernobyl nuclear power plant. The explosion dust drifted with the wind, causing Russia, Belarus, Ukraine and other places to suffer from nuclear radiation pollution.

In order to prevent the No.4 reactor after the Chernobyl nuclear explosion and the "sarcophagus" that covered its nuclear proliferation from continuing to harm the local and European countries, with the strong assistance of the European bank for reconstruction and development and international donors, the construction of the dome shaped building known as the "new safety containment body" was broken in 2010. The "new safety containment body" is 152 meters long and 106 meters high, with a total weight of more than 30000 tons. It can seal up harmful substances for up to 100 years.

The "new safety containment body" provides an example and reference for the post Fukushima nuclear pollution. Through the cooperation between the United Nations, other countries and Japan in the field of nuclear safety, feasible plans can be put forward, or a "new safety containment body" can be built in Fukushima nuclear power station to seal up the abandoned nuclear power station forever, or transfer the nuclear polluted water to a certain place in Japan to build a "new safety" The "containment body" sealed up the polluted water.

Of course, this is just a stopgap solution. In the long run, it is still necessary to develop safe, cost controllable and environment-friendly energy resources to fundamentally avoid the occurrence of similar hidden dangers.
