Speciation of Uranium Released to the Environment with Cesium-Rich Microparticles from the Fukushima Daiichi Nuclear Power Plant

Abstract

Trace U was released from the Fukushima Daiichi Nuclear Power Plant (FDNPP) during the meltdowns. The speciation of U records the meltdown processes and property of debris, and also determines the environmental impacts. This study summarizes various types of U derived from the FDNPP focusing on the speciation to provide the updated knowledge on the behaviour of nuclear fuels during the meltdowns at the FDNPP.
