The Ōma Nuclear Power Plant (大間原子力発電所 Ōma genshiryoku hatsudensho?) is a nuclear plant project in Ōma, Aomori currently undergoing preliminary ground work that would be operated by the Electric Power Development Company. The reactor would be unique in that it would be capable of using a 100% MOX fuel core, as requested by the 1995 decision by the Japanese Atomic Energy Commission. The fuel utilizes surplus plutonium by blending it with natural uranium. Reducing the total radioactivity of nuclear waste, and dramatically reduce the waste's lifetime

In 2008, Electric Power announced a 2.5-year delay to allow for additional work to make the plant resistant to a strong earthquake, making the operation start date in November 2014.[1][2]

Following the Fukushima Daiichi nuclear disaster of March 2011 construction at Oma was suspended for 18 months. Work was resumed on October 2012. On March 2013, the main reactor building was at its full height.[3]

In December 2014 Electricity Power Development Co. applied for safety checks at the Oma nuclear plant, under construction and slated for startup in 2021.[4]
