The chairman of the Nuclear Regulation Authority (NRA), Mr. Toyoshi Sarada, has asked Tokyo Electric Power Company (TEPCO) to reconsider the storage method of concrete debris with a very small amount of radioactive materials from the Fukushima Daiichi Nuclear Power Plant, with a view to temporarily burying it underground.

It has been 11 years since the accident at the Fukushima Daiichi Nuclear Power Plant occurred in March 2011. The decommissioning of the nuclear power plant involves the removal of nuclear fuel that has cooled down after melting down. The biggest challenge is to remove the fuel debris. On the other hand, the disposal of low-level radioactive waste, which is generated in large quantities every day at the decommissioning site, is also a major issue.

As a result of the hydrogen explosions in the three reactor buildings, concrete fragments were scattered.

At a meeting of the Nuclear Regulation Authority held on the 2nd, Mr. Sarada said, "Even if we assume that the waste will be transferred in the future, there are some areas where it would be much more advantageous to bury and store the waste," and expressed his desire to ask TEPCO to reconsider the storage method with a view to temporarily burying it underground.

The amount of waste from the decommissioning of the nuclear power plant is increasing, but the management at the site is not up to the task, so a realistic storage method must be considered with an eye to the future, he said.
