Hydrogen Concentration Nernst Equation Primary Containment Vessel Proton Conductor PWR Reactor Building Severe Accident Solid Oxide Electrolyte
The accident at TEPCO’s Fukushima Daiichi nuclear power plant on March 23, 2011 was expanded into severe accident (reactor damage and hydrogen explosion). It led to loss of many instrumentation systems, and became difficult to grasp plant state. The instrumentation systems for the severe accident of the nuclear plant are being developed. In order to prevent the hydrogen explosion, the hydrogen concentration sensor is desired to measure the generated hydrogen in the primary containment vessel, and to de...

AC Magnetization Method Cast iron Cementite Chill Nondestructive Evaluation
This study proposes a novel nondestructive evaluation method of chill contents in gray cast irons by means of AC magnetization method. For the purpose, magnetic properties of cast irons w ith different chill contents were evaluated by B-H loop analyzer. Results were discussed in view of matrices and graphite, and it was found that some magnetic parameters, especially B-H l oop area, correlate well with ratio of cementite area to graphite one. Focusing on the fact, AC magnetic method was applied to evaluati...

hot environment pipe-space(trench) thermal insulation
In the undergrounding pipe-space, there are many pipes for utility (electronic cable, water, gas, steam, etc.). These pipes are kept to safe by daily inspect ion. But hot environment of the pipe-space affects badly the device and a labor er's health.The investigation of the heat distribution was carried on, therefor e it was found that the radiant heat around the valve was very much. The method of thermal insulation was examined from the view point of the shape, cost, and effect. Then some of valves were ...
