"Others, including CNNC, may join the bidding process, given there is still some time before the decision will be made," Toukan told Reuters on the sidelines of a conference in Beijing.
He said it might take three years to choose the contractor and a further four or five years to build the plant, which would have generating capacity of at least 1 gigawatt, perhaps more.
At 1 GW, the plant would cost $3.3-3.5 billion. It is expected to generate around one quarter of Jordan's electricity. The country has yet to choose a site for the reactor and a lack of water was complicating the issue, Toukan said.
Jordan has reasonably assured resources of about 70,000 metric tonnes of uranium oxide in the centre of the country.
A Jordanian joint venture with Areva is exploring one block which is expected to start production in 2012-2013, while a partnership with China's Sino is in the early stage of exploring two blocks, he said.
