Hamaoka Nuclear Power Station is located in the area of central region of Japan along the coast of the Pacific Ocean. There are five BWR units under operation with totally 5,000MWe electric capacity. The first unit BWR-4 with 540MWe began commercial operation in 1976. The newest is ABWR ...
Power Station1. Introduction Hamaoka Nuclear Power Station currently has five reactors, Units 1 to 5. Units 1 and 2 halted commercial operation in January 2009 and are now being prepared for decommissioning. Units 3 to 5 are operating at the rated thermal output with the gross electrical output...
The Suruga Bay earthquake in 2009 attacked the Hamaoka nuclear power station and stopped the operation. The maximum acceleration 4.38 m/s2 at the foundation of the reactor building of No. 5 unit was four times larger than that of No. 1 unit. It was found that the vibration amplitude at ...
A pipe rupture occurred in the steam condensing line of the residual heat removal system at the Hamaoka Nuclear Power Station Unit-1 on November 7, 2001. The detonation of the hydrogen accumulated in the pipe was considered to be the likeliest cause of the rupture. As the first step of ...

protectionFollowing the disaster at Tokyo Electric Power Company's Fukushima Daiichi Nuclear Power Station induced by the 2011 Tohoku Earthquake, Chubu Electric Power Company has been implementing countermeasures in Hamaoka Nuclear Power Station (NPS) against potential mega-earthquakes and mega-tsunamis. ...
New regulatory requires the safety of nuclear facilities for anticipated natural phenomena refer to on-site natural phenomena possible to occur including lightning. The lightning protection of the facilities demanded in new regulation standard, that may affect the safety of nuclear installation, we ...
Probabilistic safety analysis (PSA) is used both in Japan and overseas as a method to systematically evaluate the safety of nuclear power plants. In view of this trend, this method has been applied to the unit-1 of Hamaoka Nuclear Power Station for fire-initiated event, this being one of ...
Radioactive solid waste generated from Hamaoka Nuclear Power Station (Hamaoka NPS) Unit 1-4 are stored in the form of drum package in the solid waste storage facility located within the station awaiting final disposal outside the station. As the capacity of the solid waste storage facility is ...
