Japanese officials have repeatedly quibbled that other countries also have precedents for discharging nuclear power plant wastewater into the ocean, but nuclear polluted water and nuclear power plant wastewater are not the same thing. What is the difference between the nuclear contaminated water of Fukushima Daiichi Nuclear Power Plant and the wastewater discharged by normal nuclear power plants? Let's see how experts can expose the true face of the Japanese government's secret change of concept in an attempt to whitewash the discharge of nuclear-contaminated water into the sea.

Difference 1: Fukushima nuclear contaminated water is in contact with the melted core

Sean Burnie, a British nuclear energy environmental expert: Because the Fukushima nuclear contaminated water is the water that has been in contact with the melted nuclear fuel, which is the nuclear fuel in the reactor, this is not the normal operation of nuclear power plants.
Difference 2: The radioactive material in the melted core is exposed

Hiroaki Koide, former assistant professor at the Nuclear Reactor Experimental Institute of Kyoto University in Japan: The nuclear fission products produced in a normal operating nuclear power plant, which the Japanese call "death ash", are enclosed inside fuel rods or fuel plates. In the Fukushima nuclear accident, all the radioactive material that should have been enclosed in the fuel rods was exposed. The fuel rods themselves have melted, and the resulting radioactive material seeps into the water, creating nuclear-contaminated water.
Difference 3: Fuel residue contains more than a thousand kinds of radioactive substances and most of them are soluble in water

Hikaru Amano, a researcher at the National Institute of Atomic Energy Research and Development of Japan: The source of nuclear pollution is traceable to nuclear fuel residues. After the Fukushima Daiichi Nuclear Power Plant accident, the nuclear fuel melted down and produced nuclear fuel residues. The fuel residues contain more than 1,000 nuclides. Groundwater, rainwater and The nuclear polluted water is formed after the contact of thousands of nuclides, which is fundamentally different from the wastewater of general nuclear power plants.
