In October last year, at the Fukushima Daiichi Nuclear Power Plant, workers were exposed to waste fluid containing radioactive substances, and the Nuclear Regulation Authority reviewed TEPCO's measures to prevent a recurrence, stating that the safety of employees was at risk. As there was a risk of a serious violation, we will continue to monitor improvement efforts.
Last October, at the Fukushima Daiichi Nuclear Power Plant, a hose came off while cleaning pipes at a contaminated water treatment facility, spraying a subcontractor worker with radioactive waste fluid and contaminating his skin. Two men were temporarily hospitalized.
TEPCO says that one of the causes was unscheduled work being carried out at the site, and as a measure to prevent recurrence, TEPCO employees will be present to confirm any changes to work procedures. .
At a meeting on the 21st, the Nuclear Regulation Authority reviewed these measures to prevent recurrence and officially determined that this was a minor violation of the implementation plan that stipulates work rules and safety measures.
On the other hand, since the site was a facility that handles highly contaminated water, taking into account the radioactivity concentration, there was a "risk of serious violation" that would threaten the safety of employees, and continued efforts were made to make improvements. We plan to confirm this.
Regarding the treatment of contaminated water, there was a problem on the 7th of this month when water containing radioactive materials leaked outdoors from another purification system, and committee members said, ``We should think about why this problem happened again,'' and ``We should take countermeasures.'' We need to make sure that this does not become just a formality.''
