At a regular meeting on the 30th, the Nuclear Regulatory Commission approved the draft regulatory standards for final disposal of the class with the highest concentration of radioactive substances among the low-level radioactive waste generated from the decommissioning of nuclear power plants. It is said that it will be buried in a place deeper than 70 meters underground. In the future, it will be officially decided after publicly soliciting opinions from the general public.

The low-level waste generated in the decommissioning is classified into “L1”, “L2”, and “L3” in descending order of concentration, and this time the target is “L1” including the core peripheral equipment such as control rods. The dismantling of all nuclear power plants in Japan except the Fukushima Daiichi nuclear power plant is expected to generate a total of 8,000 tons.

So far, there is no standard for “L1”, and the disposal site has not been selected by the business operator.
