HALF SHELL PROTECTION FOR CHAPELCROSS EFFLUENT PIPE

摘要

When the Chaptecross Magnox nuclear power station was constructed nearly fifty years ago a 6 km effluent pipe discharged up to a million gallons of cooling water daily into the Solway Firth. Although the 15 in dia pipe was originally only designed to last 25 years, several years ago it was given additional protection with Winn & Coales Denso Ultraseal Tape. Its life has now been further extended, with Denso protective materials again being specified, in order to meet the decommissioning and de-fuelling needs of the Magnox North site and to minimise the risk of discharging contaminated limescale which has built up inside the effluent pipe.
