Energy Net on 18 May 09RADIOACTIVITY leaking from a pipe, which was first spotted on the day of the Prime Minister's visit to Sellafield, had been escaping into the open for 14 months, it has been revealed. The incident has been raised to level two on the International Event scale - the highest at Sellafield since the major leak in Thorp four years ago. Sellafield Ltd said: "There is no relation between the two. The amount of radioactivity involved in this incident was very low." The leak was discovered on January 23 - the day the Prime Minister made his announcement about new reactors. The radioactivity came from an overhead ventilation duct carrying water vapour (condensate) from the Magnox reprocessing plant for dilution treatment before authorised discharge to the sea. There was a steady drip from a faulty valve flange contaminating a two metre square concrete slab. A walkway had to be cordoned off to prevent access. No workers are said to have been harmed and no contamination was found above normal background levels.
