In November 2015, we decided to conduct additional work because of the change of fire prevention measures and internal flooding countermeasures as well as the related work for seismic safety improvement, with taking account of the preceding review process of nuclear power stations of other electric utilities.
We try to steadily implement the work for further safety improvement and to complete the work at an early stage by grasping the situations of review process on our Unit 2 and other nuclear power stations and new knowledge for taking appropriate measures in advance.
We put the highest priority on safety in taking safety measures at Shika Nuclear Power Station with a firm determination to prevent an accident like that at Fukushima Daiichi Nuclear Power Station from happening again.
Construction work of the expanded emergency measures facility, installation of large volume fresh water storage tank and firebreak creation have almost been completed in March 2016 and the work for safety measures has steadily been undertaken.
Safety measures will never come to an end. We pursue the world's highest level of safety and implement safety measures in integrated cooperation with the employees of our company and partner companies working at Shika Nuclear Power Station as the close-knit "Team Shika," in order to gain trust from and bring comfort and relief to the people in the local communities.
