Commitment to maintenance of active and decommissioned nuclear power facilities.
Nuclear EnergyIn nuclear power, we supply such key equipment as reactor pressure and containment vessels and piping systems. We participate in development and construction, primarily for the back-end of the nuclear fuel cycle. Since the Great East Japan Earthquake of March 11, 2011, we have focused on improving safety at existing facilities, notably to safeguard against earthquakes, tsunamis, and terrorism at existing facilities. We have also decommissioned nuclear power plants.
