IFMIF/EVEDA Prototype Accelerator Building is a facility for validation of prototype accelerator which will be made for the Engineering Validation and Engineering Design Activity (EVEDA) of the International Fusion Material Irradiation Facility (IFMIF). This building is constructed the International Fusion Energy Research Center in Rokkasho village, Aomori prefecture, as a part of the Broader Approach activity which is an international cooperation between Japan and EU. The detail design was completed in 2007, and its construction work was started in March, 2008. The building is an one story, steel construction. The width of east-west is 58 m, north-south is 37 m, maximum height is 10.95 m, and floor area is 2019.5 m. The Accelerator Vault which made of concrete is in center of the building. The southern side is HVAC and cooling machines room, and the other side is Radio Frequebcy power supply area. Its underground was constructed in 2008, and the Accelerator Vault was constructed in May, 2009. Now, roofing work is doing. The building will be completed in May, 2010.
