At the Fukushima Daiichi NPS, water containing tritium, etc. that comes out after treating contaminated water continues to be stored in tanks, but the current plan is that TEPCO expects that the tank will fill up three years later, TEPCO Revealed. Although plans to add more tanks are being considered, the site on the premises where decommissioning work continues is limited and is likely to be discussed in the future.

In Units 1 to 3 of the Fukushima Daiichi nuclear power plant that caused the meltdown, water for cooling the nuclear fuel remaining inside was continuously added, and around 170 tons of contaminated water was generated every day.

Although radioactive materials are being removed, some radioactive materials such as tritium remain. So far, nearly 1,000 tanks have been built on the premises, and approximately 1.15 million tons have been stored as of last month.

TEPCO plans to add more tanks until the end of next year, but there is no plan after that, and if it stays as it is, it is revealed on the 8th that the tank will be full in the summer of 2022 three years later.

TEPCO has designed a large tank and is considering a plan to install it on the ground, below ground, or on the sea, but if the tank breaks, there is a risk of leakage, as well as spent nuclear fuel or molten nuclear fuel on the premises. It was also necessary to construct facilities to store the tanks, and he also expressed his view that securing land for tanks would become stricter in the future.

For water containing tritium,
▽ Continue to make tanks and store them for a long time,
▽ A plan to lower the concentration of radioactive material and release it to the sea,
▽ A plan to evaporate and release it into the atmosphere,
▽ A plan to pour into a place deeper than 2000 meters underground,
Several methods have been examined, but there are strong opposition from local fishermen's cooperatives and residents to promote damage to reputation even if the pollution is below the standard for methods that release it into the environment such as the sea.

The country continues discussions by experts, but the policy has not yet been decided, and it is likely to be discussed in the future.
