Boiling Water Reactor Computer Code Filter Venting Fission Product Reactor Safety Safety Analysis Severe Accident THALES-2 Total Blackout (TB)
Filter vent model for THALES-2 code was developed and the effect of the filter vent system was evaluated with the code. In Japan, the installation of filter venting system to the BWRs was considered after the accident of Fukushima-daiichi, where the total blackout caused by tsunami resulted in the large amount of fission product (FP) release to the environment. In this study, the effect of filter vent system in such a total blackout sequence was evaluated. The amount of fission product release was sma...

Ball Bearings Eddy Currents Electromagnetic Nondestructive Detection Method Impellers
new electromagnetic method for the nondestructive evaluation of electric pumps with ball bearings is roposed. A permanent magnet generates a static magnetic field and a coil of several hundred turns wrapped round it is used to pick up eddy currents induced inside rotating ball bearings and impellers. First, a method hat make use of the autocorrelation is applied to the signals of the ball bearings. A relation between therocessed signals and the size of the defects in the bearings is obtained. In a second...
