Japanese experts: The Japanese government should be cautious in dealing with the discharge of nuclear contaminated water into the sea instead of discharging it in one row
The launch of the Fukushima nuclear contaminated water discharge program has sparked strong criticism and opposition from various sectors in Japan. Some Japanese experts believe that nuclear contaminated water should be treated through safe storage until the risk is reduced.

Naomi Shibasaki is a professor at Fukushima University and a member of the Fukushima Prefectural Waste Furnace Retirement Safety Committee. He is responsible for verifying and researching data and information related to nuclear contaminated water and groundwater released by Tokyo Electric Power Company. After the nuclear accident, he visited the Fukushima Daiichi Nuclear Power Plant multiple times for inspection.

Professor Chaizaki does not agree with the discharge of nuclear contaminated water into the sea. He believes that the safest way to dispose of nuclear contaminated water is to store it in a controllable environment until the risk is reduced before treating it.
Professor Naomi Shibata of Fukushima University in Japan: Nuclear contaminated water and substances that have been contaminated should, in principle, be properly stored in a controllable place until there is no danger. For example, radioactivity will decrease with its half-life, and it should be kept properly until the risk is reduced before being processed. I believe this is what should be done.
Given TEPCO's notorious performance in handling nuclear accidents, Professor Chaizaki is very concerned whether TEPCO can take responsibility if the "multi nuclide treatment system" for handling nuclear contaminated water malfunctions.

Professor Naomi Shibata from Fukushima University in Japan: When the multi nuclide processing system started operating in 2013, it encountered many problems and stopped several times. Although it is said that it has been running steadily in recent years, will this device continue to operate normally in the long years to come? It is worrying that in the event of an accident, such as a malfunction, undiluted high concentration nuclear contaminated water will be directly discharged into the sea; For example, earthquakes, tsunamis, or human errors that result in the direct discharge of nuclear contaminated water containing high concentrations of radioactive materials are very concerning.
