Beijing, Aug 14 (Xinhua) Deputy director of China's National Energy Administration Sun Qin has been appointed as the country's nuclear agency chief.

Sun replaced Kang Rixin, general manager of the China National Nuclear Corporation (CNNC), after he was sacked following alleged 'grave violations of discipline', sources with the Central Committee of China's Communist Party said Friday.

Kang, a member of the CPC Central Committee since October 2007, was also the secretary of the corporation's CPC Leadership Group.

He has held the post of the corporation's general manager and Party secretary since September 2003.
