CAEP meaning in Academic & Science ?

China Academy of Engineering Physics (CAEP) (Chinese: 中国工程物理研究院, nicknamed 九院) was founded in October 1958. The CAEP is China's organization conducting the research, development, and testing of nuclear weapons and related science. Formerly called the Ninth Institute, CAEP 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, major components of the CAEP and China's nuclear weapons research, development, and production were moved to Sichuan Province to avoid detection by foreign powers. The academy was formerly named the Ninth Academy (or Institute) of the Second Ministry of Machine Industry. It was renamed the China (or Chinese) Academy of Engineering Physics in the 1980s.
