Councillors in Londonderry are to hear a local businessman's proposals to build a nuclear power plant in the city later on Thursday.
A nuclear power plant for Londonderry has been proposed
Robert Andrews said it would meet future energy needs in Northern Ireland and provide hundreds of jobs.
He admited there was a risk with the nuclear waste but said it could be dealt with "safely".
However, Dr Peter Doran of the Green Party said it could become a "target for international terrorism".
Mr Andrews said he wanted a plant that would generate about 2,000 megawatt hours based at the old power station in Coolkeeragh.
He said that to generate the same amount of power using wind would require 300,000 windfarms throughout Ireland.
"I believe from a technical point of view that it is safe, it is efficient, it is very profitable," he said.
"For example if a nuclear power station were in Derry it would produce 500 permanent jobs. Nuclear power stations last 60 years so that's 500 jobs for 60 years."
Robert Andrews said a nuclear power station would bring jobs
Mr Doran said the Sustainable Development Commission's report to the prime minister had noted nuclear power plants could be terror targets.
"The advocates of a nuclear power plant in Derry would be placing every man, woman and child in Derry in the front line in Tony Blair's war against international terrorism," he said.
He said that the idea would also sound the "death knell" for tourism in the area.
John Woods from Friends of the Earth said that Ireland did not need a nuclear power plant.
"There are lots of other ways of creating jobs, primarily through renewable energy," he added.
