The China Experimental Fast Reactor (CEFR) is China's first fast nuclear reactor, and is located outside Beijing at the China Institute of Atomic Energy. It aims to provide China with fast-reactor design, construction, and operational experience, and will be a key facility for testing and researching components and materials to be used in subsequent fast reactors. It achieved first criticality on July 21, 2010. It started generating power a year later on July 21, 2011. Japan's Atomic Energy Agency (AEA) reported that the reactor stopped generating electricity in October 2011 following an accident; the director of the China Institute of Atomic Energy (CIAE) denied that any accident had occurred however. CEFR is a 65 MW (thermal), 20 MW (electric), sodium-cooled, pool-type reactor with a 30-year design lifetime and a target burnup of 100 MWd/kg. On 2012-10-31 Xinhua announced that the CEFR has passed official checks.
