CHINA'S hunger for uranium to underpin the expansion of its nuclear industry has not been curbed by the Fukushima disaster, according to the country's main energy agency.

On the same day that China's Hanlong Mining was outed as the $144 million suitor of WA uranium junior Bannerman Resources, National Energy Commission advisory board chairman Zhang Guobao told the Boao Forum for Asia Perth conference his country's nuclear expansion plans were on track.

''It is no longer feasible to continue to rely on fossil fuels - developing nuclear power is a choice of must,'' he told the gathering of Chinese and Australian political and business leaders.

He said there were 13 operational nuclear power plants in China with another 28 under construction to take capacity to nearly 40 gigawatts by 2015.

''And we have stayed firm on this plan,'' he said.
