China built the Northwest Nuclear Weapons Research and Design Academy in the early 1960s based on Soviet plans.  The academy was the site of much of China’s early weapons design work, including the development of China’s first atom bomb and first hydrogen bomb. It had sites for “high explosive and fissile component production, general component (cases, electrical systems) production, final weapons assembly, HE component testing, and environment testing.”  It was also the earliest site for centralized storage of nuclear weapons. 
In 1987, China decided to decommission the site, with all capacities transferred to the Chinese Academy of Engineering Physics (CAEP) in Mianyang. In 1995 control of the land and equipment was transferred to the Qinghai Provincial People’s Government, under the new name of Xihai town.  The site is currently open as a tourist site called the “Atomic City,” and was designated a National Patriotism Education Base to commemorate China’s efforts and accomplishments in developing the atomic bomb.
