We have been engaging tsunami countermeasures including tsunami protection wall at Hamaoka Nuclear Power Station since the Great East Japan Earthquake disaster. In the design of the wall, the innovative structure type integrated L-shaped wall sections of SRC and steel structure on RC underground wall foundations implanted into solid bedrock was developed. This structure gives an extra safety margin to seismic-resistant and tsunami-resistant design. Moreover we achieved to shorten the construction term...

Design and Construction of "Tsunami Protection Wall" at Hamaoka Nuclear Power Station

If the wireless communication is feasible in the concrete structure of power plants, it is effective for us to reduce the construction cost, improve the placement of equipment and change facilities easily. In buildings of such a power plant, the reinforced concrete (RC) walls might be more than one meter in thickness, with high rebar density. Therefore, radio wave transmission over this kind of concrete walls was studied to discuss feasibility. Aperture parts of walls, such as doors, whose thickness is ...
