[1D04] Investigation of in-reactor cesium chemical behavior in TEPCO's Fukushima Daiichi Nuclear Power Station accident
(12)Analysis of nuclides in samples collected from primary containment vessel of Unit 1
Keywords:Fukushima Daiichi Nuclear Power Station accident, Alpha spectrometry, Gamma-ray spectrometry, Inductively Coupled Plasma Mass Spectrometry
Samples, collected from primary containment vessel of Fukushima Daiichi Unit 1, were immersed in nitric acid. Immersed solutions were analyzed by alpha spectrometry, gamma-ray spectrometry and ICP-MS. Analyses provided similar results with the past measurement and suggest small amount of Pu, Am, and Cm.
