The Second Ministry of Machine Building was a government ministry of the People's Republic of China which oversaw the nuclear industry of China.
In February 1958, China's Third Ministry of Machine Building was renamed the Second Ministry of Machine Building. It had a month earlier established the Ninth Bureau, which was responsible for nuclear weapons research and design.
In 1958, the National Defense Science and Technology Commission was established with Marshal Nie Rongzhen as its director to oversee the Second Ministry of Machine Building as well as the Lop Nur Nuclear Weapon Test Base and the Fifth Academy of the Defense Ministry.
In July 1958, the Second Ministry approved plans to set up a nuclear research institute on Huayuan Road in Beijing to receive and study technical assistance which the Soviet Union had promised under the New Defense Technical Accord.
In May 1982, the Second Ministry was renamed the Nuclear Industry Ministry. In 1988 the Ministry of Nuclear Industry was re-organised and became the China National Nuclear Corporation.
In April 1988, the Second Ministry became part of the newly created Ministry of Energy Resources.
