JAERI Reprocessing Test Facility(JRTF)
The JRTF facility was constructed in 1966 by JAERI which was the predecessor of JAEA, and was operated for the first reprocessing test in Japan during the period 1968-1969. As the result of the test, about 200 g of plutonium was extracted by the Purex process. After that, R&D of reprocessing and evaluation of fuel burn-up were conducted at the JRTF. Decommissioning of the JRTF facility started in 1990, and the actual dismantling activity began in 1996.

Decontamination Method for Concrete Surfaces by YAG-Laser
This technology purposes to remove the contaminated outer layer of concrete structures efficiently by means of an irradiating laser of high energy density that causes melting and vitrification of the concrete's silica and alumina components.
