The Japanese expert panel "ALPS subcommittee", chaired by nuclear scientist Ichiro Yamamoto, released a report in January 2020 which calculated that discharging all the water to the sea in one year would cause a radiation dose of 0.81 microsieverts to the locals, therefore it is negligible as compared to the Japanese' natural radiation of 2,100 ...
The Fukushima nuclear accident was a major nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima, Japan, which began on 11 March 2011. The proximate cause of the accident was the 2011 Tōhoku earthquake and tsunami , which resulted in electrical grid failure and damaged nearly all of the power plant's backup energy ...
the Japanese government would help local authorities with disposing of the enormous amount of radioactive waste. [108] On 19 December 2011, the Japanese Ministry of Environment published more details about these plans for decontamination: the work would be subsidized in 102 villages and towns.
Japan also lacks a final repository for high-level nuclear waste. An intermediate facility is designed to keep nuclear spent fuel in dry casks for decades until it is moved to a reprocessing or to ...
Japan on Friday revised a roadmap for the cleanup of the tsunami-wrecked Fukushima nuclear plant, further delaying the removal of thousands of spent fuel units that remain in cooling pools since ...
The U.N. nuclear agency gave its endorsement on Tuesday to Japan’s planned release of treated radioactive wastewater into the sea from the damaged Fukushima nuclear plant, saying it meets ...
Fukushima Daiichi nuclear plant cooling water dumped (leaked) to the sea – TEPCO estimate 4.7x10 15 Bq, Japanese Nuclear Safety Commission estimate 15x10 15 Bq, [8] French Nuclear Safety Committee estimate 27x10 15 Bq. [9] Naturally occurring Potassium 40 in all oceans – 14,000,000x10 15 Bq. [10]
In 2000, a Specified Radioactive Waste Final Disposal Act called for creation of a new organization to manage high level radioactive waste, and later that year the Nuclear Waste Management Organization of Japan (NUMO) was established under the jurisdiction of the Ministry of Economy, Trade and Industry.
