China has followed a rational, coordinated and balanced nuclear safety and security approach in developing nuclear energy, a senior Chinese official said on Monday.

Tang Dengjie, head of the Chinese delegation to the UN atomic agency IAEA's 61th General Conference held in Vienna, made the remarks while addressing the opening of the conference.

China stick to the policy for efficient development of nuclear power on the basis of safety and security, said Tang, who is also chairman of the China Atomic Energy Authority and vice minister of the Ministry of Industry and Information Technology.

The Nuclear Safety Law, which was passed earlier this month by China's top legislature or the National People's Congress, will provide a strong support for the safe and sustainable development of nuclear energy in China, he said.

Since the Fukushima nuclear accident in 2011, comprehensive safety inspections have been carried out on all nuclear installations and facilities in China, Tang said.

Tang said China has been supporting the International Atomic Energy Agency (IAEA) to play a leading role in international nuclear security cooperation.

Last month, an IAEA expert mission visited China to carry out the International Physical Protection Advisory Service (IPPAS), which provided beneficial recommendations and suggestions for China to strengthen its nuclear security capability building.

China currently has 36 operational nuclear reactors and is building 20 more.

By the end of 2020, China aims to have 58 million kilowatts of nuclear power capacity in operation and more than 30 million kilowatts under construction.
