China Academy of Engineering Physics

CAEP was formerly called the Ninth Institute or Ninth Academy of the Second Ministry of Machine Industry. The research group was initially located in Beijing. Major components of its nuclear program were relocated to Qinghai Province in the 1950s. After China's first nuclear test in 1964, the institute and its activities (nuclear weapons research, development, and production) were moved to Sichuan Province to avoid detection by foreign powers. ==Organization==

The CAEP headquarters, since the 1980s, is in the 839 area of Mianyang and covers a land area of 5 km2. It is also nicknamed Scientific Town. It has multiple outlets located in Beijing, Jiangyou, Mianyang, Chengdu, and Shanghai. Controversies CAEP and some of its related institutes and companies has been on the United States Department of Commerce's Entity List since 1997. == CAEP Institutes ==
