Millions of gallons of contaminated water are pumped from Sellafield into the Irish Sea every day. This in itself is worrying but it is compounded by the succession of accidents which have made it the worst managed nuclear waste plant in Europe. The court rejected the Irish demand for an end to radioactive discharges from the mixed oxide plant at Sellafield as Ireland had not proved that the MOX plant was causing serious harm to our marine environment. However, the tribunal has agreed to allow Ireland to apply for provisional measures to protect the marine environment against serious pollution.
