Gerry Cole, chairman of the Cumbrian Construction Workers, had to be reminded of the libel laws by Chris McDonald, the Department of the Environment inspector conducting the inquiry, as he heaped insults on Friends of the Earth, Greenpeace and other groups which he said wanted to prevent people from "honest, fulfilling work".
The inquiry, which began at Cleator Moor Civic Hall six weeks ago, is into UK Nirex's plan for a pounds 195m rock laboratory at Gosforth on the edge of the Lake District National Park. Nirex wants to prove the scientific case for a pounds 2.5bn deep repository to take waste from British Nuclear Fuel's Sellafield reprocessing plant, two miles from the site.
The Government is anxious to settle the issue of waste management - which is jeopardising its plans to sell off the nuclear power industry and raise up to pounds 3bn for pre-election tax cuts. But uncertainty could force down the price.
Mr McDonald disappointed Nirex by asking the independent Pollution Inspectorate to give evidence next week. He also indicated that his report would be delayed. The issue must then be decided by John Gummer, Secretary of State. A further uncertainty has been added with the disclosure that the European Commission has opened an official complaint file on the Nirex "environmental statement".
Speaking on behalf of four local FoE groups, Jill Perry said Sellafield had been chosen, against other sites, on the basis of cost, convenience and an amenable local population. She argued that the volcanic rock in which the radioactive waste will be sealed was "inherently fractured" and close to recently active geological faults.
Mr Cole attacked the anti-nuclear groups as "professional agitators and protesters". Describing himself as "a hairy-arsed old construction worker" who wanted to see his men in work, he said 2,000 jobs were at stake.
The underground laboratory was also supported by the Windscale and Calder Shop Stewards Committee representing 4,800 employees at BNFL Sellafield.Reuse content
