VIDEO: Strikes Hit UK Energy Plants

A British Energy spokesman said the plants were operating normally and safely despite the action.

Energy supply has not been disrupted after hundreds of workers at key British power, energy and nuclear sites protested over the use of foreign workers as recession deepens.

The walkouts, which appeared to be spreading on Monday, have so far mostly affected sites in the east and northwest of Britain. The main plants targeted by the protests are:

* The Sellafield nuclear reprocessing site in Cumbria, northwest England, where 900 contractors walked out on Monday. Facilities include the Thorp nuclear fuel reprocessing plant and the Magnox reprocessing plant.

A British Energy spokesman said the plants were operating normally and safely despite the action.

* Heysham nuclear power plant in Lancashire, northwest England where 300 contract workers have left their posts.

* Fiddler's Ferry power station in the town of Widnes, northern England, where 300 workers have downed tools.

* Total's, 200,000 barrel per day (bpd), Lindsey refinery in eastern England, where contractors staged fresh demonstrations on Monday. Total said the protests, which began last week and helped sparked others nationwide, had not affected production and supply of fuels.

* UK chemical firm Ineos Group's, 200,000 bpd, Grangemouth oil refinery in Scotland. Up to 500 contract workers, involved in scaffolding, insulation and decorating, continue to take action.

A spokesman for operator Ineos said the plant was "operating normally", and expected the workers to return on Tuesday.

* Petroplus, owner of the 35,000 bpd Coryton oil refinery in Thurrock, Essex, said a number of workers had walked out. But strikers were from construction companies and operations were unaffected.

* 180 contractors walked out at one of Shell's gas sites, Mosmorran. Workers returned today at the St Fergus gas facility. There were no walk-outs at the company's 245,000 bpd Stanlow oil refinery.

"It's business as usual and production is not affected," a Shell spokeswoman said.

* A small number of contract workers walked out of Chevron's 220,000 bpd Pembroke refinery on Friday, but there was no impact on production. All workers and contractors were back to work on Monday at the refinery in Wales.

* Smaller scale protests have also taken place at RWE Power's Aberthaw power station in south Wales and ExxonMobil's ethylene plant in Fife, Scotland.
