China National Nuclear Power Co Ltd plans to raise 16.3 billion yuan ($2.60 billion) in the industry's first initial public offering, as part of the world's biggest expansion of civilian nuclear power capacity.

The listing, if approved by the securities regulator, could be the largest on the Chinese mainland since Agricultural Bank of China Ltd in July 2010 - though Guotai Junan Securities Co Ltd could take that accolade after applying for an IPO to raise 22 billion yuan, based on Reu ters calculations.

State-owned China National Nuclear Power said in a preliminary prospectus on the regulator's website that it plans to sell 3.651 billion shares, or 25 percent of its enlarged capital base, to fund projects and replenish working capital.

The listing would be part of the government's drive toward cleaner energy, under which it aims for installed nuclear power capacity of 58 gigawatts by 2020 from 14.6 gigawatts in 2013, rising to 200 gigawatts by 2030.

Expansion was suspended after the 2011 nuclear disaster at Fukushima, Japan, but plant construction is widely expected to resume in coming months.

China, the world's largest power producer, has emerged as the biggest market for nuclear plants . The country generates less than 2 percent of electricity from 17 nuclear reactors - nine owned by China National Nuclear Power and the rest by State-owned China General Nuclear Power Corporation.

Last year, China National Nuclear Power won a contract to build two reactors for the Karachi Coastal Nuclear Power Project in Pakistan at a cost of $9.59 billion.
