Because earthquakes occur frequently in Japan, attention has been given to seismic safety in the design and construction of Japanese nuclear power facilities. A serious accident at the Fukushima Dai-ichi Nuclear Power Plant of the Tokyo Electric Power Company that was caused by the 2011 Great East Japan Earthquake prompted us to review measures to ensure structural safety against future earthquakes and tsunamis. In recent years, progress has been made in investigations and research on the earthquake-resistant design of nuclear power plants. This has contributed to the development of various new technologies based on the new findings. As examples of future technologies for the seismic safety of nuclear power facilities, this chapter describes structure control technologies for nuclear power facilities and technologies to allow for greater diversity in the siting of nuclear power plants.
