Collapse Dynamic load Frequency ratio Input energy Piping
According to experimental observations, as the failure modes of piping in nuclear power plants caused by large seismic motion, ratchet collapse was observed. Ratchet collapse is the collapse which is followed by ratchet deformation. However, the mechanism of ratchet collapse under the large seismic load is not so clear. In order to clarify ratchet collapse, it is important to examine ratchet deformation and collapse at first. Ratchet deformation occurrence condition and mechanism have already been clear. In...

Catalytic Combustible Hydrogen Concentration Primary Containment Vessel PWR Severe Accident Thermal Conductivity
Mitsubishi Heavy Industries, LTD (MHI) developed accident tolerant in-containment hydrogen monitoring system that can operate under harsh environmental conditions during severe accident. The new hydrogen monitoring system consists of two types of detectors, which have different features and operating principles such as high sensitivity (for monitoring low hydrogen concentration) and wide range (for monitoring high hydrogen concentration of up to 20vol%), and hydrogen indication and transmitting module...
