[1D02] Similarity of composition between silicate glass of the Type A insoluble Cs particles and filtersof stand-by gas treatment system line in Unit 3
Keywords:Insoluble Cs particles (Type A), Silicon, HEPA filter, Electron probe micro analyzer, Fukushima Dai-ichi Nuclear Power Plant accident
The structural component of glass fiber of HEPA filter in Unit 3 was analyzed by EPMA to confirm recently proposed formation mechanism of insoluble Cs particles released during the Fukushima Accident. The results suggested that the silicon in the Type A of insoluble Cs particles was derived from the HEPA filter in Unit 3.
