Various radioactive wastes generated in Fukushima Daiichi Nuclear Power Station should be safely disposed of. The properties of the wastes are required to understand. For that, the wastes are sampled and performed analyses. To utilize obtained analytical data, the database "FRAnDLi" was made to provide the data through the Internet.

To study on treatment and disposal of solid waste generated at Fukushima Daiichi NPS (1F), radionuclide composition of sample taken from the bottom of primary containment vessel (PCV) of unit 1 was acquired by radioactivity analysis. It was the first time that nuclide composition data of samples taken from the inside of the reactor had been acquired, and the acquisition of these data will make it possible to estimate the origin of contaminants.

In order to clarify the chemical species of alpha nuclides in the contaminated water of the Fukushima Daiichi Nuclear Power Station, sludge was classified by particle size. The concentration of alpha radioisotope was measured and the particles were investigated. Most alpha particles were larger than 10 micrometers and settled at the bottom of the torus chamber.
