CLADS-Collecting the wisdom of experts from around the world
The CLADS was established in Tokai-mura, Ibaraki Prefecture aiming to conduct research and development towards
the decommissioning of 1F while collecting the wisdom from around the world. As a core of the research anddevelopment, the "International Collaborative Research Building" was constructed in Tomioka Town near the 1F site.
Also, we constructed the network where human resources in domestic/foreign universities, research institutes, andindustries can interact. Thereby, we are integrally proceeding research/development and human resource
development for the decommissioning of 1F.

Okuma Analysis and Research Center-Analysis and research of fuel debris etc.
The Okuma Analysis and ResearchCenter is a facility where radioactive
wastes and fuel debris produced in
the 1F are analyzed and researched.
The Center is now under construction
in Okuma Town, adjacent to 1F.

(I) Example for R&D:Technology for remote analysis of fuel debris using laser.
The Laser Induced Breakdown Spectroscopy (LIBS) is a method to analyze chemical composition of a sample by irradiating
laser using an optical fiber. In order to apply the LIBS to the analysis of fuel debris that cannot be brought out due to the highradiation, the tip of the radiation-resistive optical fiber is brought close to the fuel debris. By doing so, we are developing
remote-analysis technology that can determine the chemical composition of the sample in a short time.
