Fukushima Daiichi nuclear power plant treats water after treatment again for testing after September 23:40 on July 30

TEPCO announced that it will carry out a test after September this year to remove radioactive substances that exceed the standard remaining in the water after treating the contaminated water at the Fukushima Daiichi Nuclear Power Station. However, the radioactive material tritium cannot be removed because it is difficult to separate it from water with current technology.

At the Fukushima Daiichi Nuclear Power Plant, water containing radioactive substances such as tritium after treating contaminated water has accumulated 1.2 million tons in about 1,000 tanks.

Water is once treated to remove radioactive substances, but some of the radioactive substances are still above the concentration standard, so TEPCO plans to treat it again this year. Since then, we have clarified a plan to test about 2000 tons. The results will be summarized later this year.

However, among the radioactive substances, tritium cannot be removed because it is difficult to separate it from water with current technology.

Akira Ono, Representative of TEPCO's Fukushima Daiichi Decommissioning Promotion Company, said, "If the performance can be confirmed in the test, we would like to proceed to the secondary treatment. There are issues such as having to secure the tank capacity, so what kind of setup do you proceed? I want to think about it."
