The following measures are taken to secure the safety of the workers and a sufficient number of workers in the Fukushima Daiichi nuclear power station, where the work towards the decommissioning of the reactors has been performed according to the Mid-and-long-Term Roadmap.

Ensuring the APD usage and collaboration with cooperative companies
  • Recurrence prevention measures are implemented in response to the inappropriate APD usage.

  Principal measures:
  1. TEPCO supervisors or main contractor employees check for APD usage when they visit the work site without prior notice.
  2. Wear protective clothing with its chest area transparent to facilitate checking.
  3. Identify employees who must have an APD (target of checking)
  • Reduce burden on workers by implementing work environment improvements such as the non-requirement of face masks and breathable tyveks.
  • A survey on working conditions was performed to understand the actual conditions of the working
