R&D on Decommissioning and Radioactive Waste Management

Waste Management and Decontamination Facilities in the Oarai site

Waste management facilities systematically and safety collect, treat and store radioactive wastes. Radioactive wastes treated in the facilities are low level solid/liquid wastes generated from the nuclear reactors and nuclear fuel handling facilities in JAEA’s Oarai site, the Institute for Materials Research of Tohoku University and Nippon Nuclear Fuel Development Co., Ltd.

Technology Development for Decommissioning

Decommissioning of nuclear facilities are being carried out while developing technologies for rational implementation by reducing the amount of radioactive waste generation and the cost on the premise of ensuring safety.

Technology Development for Radioactive Waste Treatment and Disposal

Radioactive wastes generated in the Oarai site have been properly treated and stored while collecting data on their physical charac-teristics required for near-surface disposal. In addition, Oarai Waste Reduction Treatment Facility(OWTF), a new facility for reducing the volume of high-level solid waste, is under test operation.
