Concreate High temperature Magnesia-Carbon brick Thermal deterioration Void ratio
In the Fukushima daiichi accident, molten core supposed to be leaked from the pressure vessel to the concreate floor in the containment vessel. To keep the integrity of the containment, development of small type of core catcher which can be installed in present nuclear power plant is needed. In this investigation, the thermal deterioration of concreate and Magnesia-Carbon brick was evaluated by the surface observation and the measurements of compressive strength, weight reduction, and difference of void r...

In Fukushima accident on 2011, molten core supposed to be leaked on the concreate floor in containment vessel. Development of small type of core catcher which can be installed in operating nuclear power plant is needed. In this investigation, the thermal deterioration of concreate and Magnesia-Carbon brick observed trough surface observation by microscope and measurement of compressive strength, weight reduction, and difference of void ratio. In addition, permeability measurement for burned concreate was op...

Boiled Water Reactors Primarily Loop Recirculation Piping Saddle-shaped Welds Ultrasonic Depth-sizing
In order to determine crack depth in primarily loop recirculation (PLR) piping of boiling water reactors, ultrasonic angle beam testing using time of flight measurement of the diffracted signal from the crack tip, is employed. There are some power stations in Japan having saddle-shaped weld joints at branch connections in PLR piping. If the angle beam testing is applied without considering curvature of saddle-shaped weld joints, unlike weld joints of straight piping, it can be predicted that determine...

droplet diameter droplet parameter erosion rate high-speed spray Liquid droplet impingement erosion number of droplet velocity
The erosion rate of aluminum material by liquid droplet impingement erosion is studied by using high speed spray. In order to propose an accurate prediction method, a new experimental data are obtained by using the spray erosion larger than the scale of specimen, which allo ws a constant erosion rate, while it is not for the previous method. The new experimental data shows that the erosion rate is proportiona l to the power of 7 of the droplet velocity, which results in a highly accurate prediction method...
