Nuclear Regulatory Commission Investigation of nuclear accident resumed Investigation into release route, etc. October 19, 4:05

Regarding the accident at the Fukushima Daiichi Nuclear Power Station, the Nuclear Regulatory Commission has resumed the study group to investigate the cause of the accident, and at the first meeting on the 18th, proceeded with investigation and analysis on three themes, including the release route of radioactive materials I decided to go.

After the accident at the Fukushima Daiichi nuclear power plant, the Nuclear Regulatory Commission set up a study group to investigate and analyze the cause, and after five years ago (H26) compiled the report, it was temporarily suspended.

After that, because the radiation dose at the site decreased, and it became possible to collect and investigate new data, the study meeting was decided to resume, and the first meeting was held on the 18th.

In this, major future policies were discussed, and accident investigations were conducted on three main themes: how to lower the pressure in the reactor containment vessel, the release route of radioactive materials, and how the reactor was cooled. I decided to proceed with the analysis.

During the meeting, Mr. Toyoshi Sarada, Chairman of the Nuclear Regulatory Commission, said, “For example, if we talk about the device that lowers pressure, we would like to investigate from the design philosophy itself,” as well as TEPCO participating in the observer. The person in charge said, “I think I ’ll challenge a place I ’ve never been to before. I want to make adjustments.”

The study group plans to conduct a field survey at the Fukushima Daiichi nuclear power plant in the future, and wants to compile a report for the next year.
