A Plant data evaluation for Fukushima-Daiichi NPP Unit 3

Sato, Ikken

no journal, , 

The PCV pressure measurement of Fukushima-Daiichi NPP Unit 3 showed cyclic pressure up and down. Although some early pressure changes of them can be regarded as consequence of venting actions, later changes are not likely due to venting nor significant leakage through the PCV boundary. In this study, preliminary correction for pressure measurement data was applied based on assumed consistency among different pressure measurement data. With this correction, subtle pressure differences among RPV, D/W and S/C became visible and information related to accident progression was obtained. With this knowledge, possible mechanism of PCV pressure decrease by itself will be reported.

Studies on relocation behavior of molten core materials in the core disruptive accident of sodium-cooled fast reactors, 6; A Modelling of the tip of a heavy metal jet with MPS method

Konomura, Mamoru*; Kamiyama, Kenji

no journal, , 

A behavior of a heavy metal jet which ran into a water pool was analyzed with the Moving Particle Semi-implicit Method. A figure of the tip of jet was different from that of the experiment. We propose a modified calculating model with the MPS method.
