With regard to the disposal of water, including tritium, which is increasing at TEPCO’s Fukushima Daiichi Nuclear Power Plant, the Ministry of Economy, Trade and Industry this week presented to local governments in Fukushima Prefecture measures such as measures based on the premises of ocean release, while the Ministry of Economy, Trade and Industry compiled the results of a study that examined three proposals for storing outside the site of nuclear power plants and solidifying them with concrete, which were issued at meetings to hear opinions.

The Ministry of Economy, Trade and Industry has been holding meetings since spring to hear opinions from local residents and related organizations regarding the disposal of water containing tritium and other radioactive materials that continue to accumulate in tanks at the Fukushima Daiichi Nuclear Power Plant, and has been recruiting opinions from the general public.

In addition to the proposal to solidify it with mortar, which has a proven track record overseas, there were opinions that asked for consideration on proposals to transfer to remote islands by ship and to carry it outside the site of the nuclear power plant for storage and disposal.

As a result of technical studies, the Ministry of Economy, Trade and Industry said that solidifying concrete would increase the volume and make it difficult to secure the site, and that the plan to transfer it to remote islands by ship would require large-scale facilities and take time.

In addition, the idea of transporting water off-site through containers and drainage routes was difficult due to regulations.

On the other hand, the evaluation of the subcommittee of the country in February is shown again, and it is realistic about the marine release.

The Ministry of Economy, Trade and Industry (METO) has indicated to local governments in Fukushima Prefecture this week that it will take measures against reputation on the premise of ocean release, and is expected to make final adjustments around ocean release in the future.
