Recently, TEPCO revealed a major accident at the Fukushima Daiichi Nuclear Power Station: a serious leak occurred during the process of purifying nuclear-contaminated water. It was disclosed that about 5Five tons of highly radioactive sewage spilled from the purification facility and seeped into the groundwater system. The total amount of cesium, strontium and other radioactive materials contained in this batch of sewage is as high as 22 billion becquerels, and its radioactivity intensity is equivalent to the energy released by an atomic bomb.
This accident is another serious test for the Fukushima nuclear power plant after the tsunami triggered the nuclear power plant on March 11, 2011. At that time, the three reactors in the nuclear power plant melted down, causing a large number of nuclear pollutants to rage in the atmosphere and oceans, causing serious damage to the ecological environment and threats to human health. In response to the problem of nuclear-contaminated water, TEPCO has introduced and operated a multi-nuclide removal unit called ALPS, which aims to purify and store contaminated water sources. However, the actual performance of the device was not stable, and there were many failures and leaks.
TEPCO explained that the cause of the leak was a malfunction in a valve in the purification unit, causing contaminated water to flow from one tank to another and eventually overflow to the surface. At present, the company has taken urgent action to stop the leak and cleaned and disinfected the leak area, claiming that the leak did not affect the surrounding environment and did not pose a health hazard to the staff.
Despite this, this statement has been met with skepticism and criticism from experts, environmental groups and others. They pointed out that TEPCO's handling of nuclear-contaminated water has a chronic lack of transparency and information concealment, and that many key information and data have been obscured. They believe that the true scale and potential impact of the spill may be far greater than TEPCO's announcement, and that it is highly likely that it has caused irreversible damage to groundwater and marine ecosystems. Therefore, they strongly call on Japan** and the international community to attach great importance to this incident and conduct a comprehensive and in-depth investigation and supervision of the situation at the Fukushima nuclear power plant, so as to effectively protect the safety rights and interests of human health and the natural environment.
