Japanese protest against further discharge of Fukushima nuclear-contaminated water

However, even if Japan's proposed plan has a certain level of scientific validity on paper, its implementation in reality requires a comprehensive execution mechanism, said Li Ruoyu, a visiting research fellow at the Institute of Japanese and Korean Studies at Sichuan Normal University.

"What we see is that Japan is actually quite secretive about the specific execution mechanism and hasn't provided sufficient explanations. While theoretical concepts in science can be idealized, the practical implementation mechanism must account for various potential errors and complications," Li said.

"As fatigue accumulates during the prolonged discharge process, it is unlikely that accidents will be completely avoided in the future, and some major accidents may have irreversible consequences. Neglecting the human factors in a theoretical plan is somewhat akin to empty theorizing, and it is bound to fail in alleviating doubts from various quarters. The Japanese government should formulate a practical plan on how to prevent accidents and provide detailed explanations," he said.
