Magnox Ltd has begun work on the final piece of the decommissioning jigsaw at the former Steam Generating Heavy Water Reactor (SGHWR) on the Winfrith site in Dorset. The SGHWR reactor needs to be isolated from adjacent plant and equipment so that the Magnox Ltd team can gain access to the reactor’s core and begin to safely dismantle it. This project will be completed early next year. It will involve the removal of 1.5km of stainless steel pipework. So far, months of planning and preparation have been necessary because of the complex nature of the project. The Magnox Ltd team has rehearsed, at minimal risk, using specially created full-scale mock-ups of the plant. Lessons learnt from this practice exercise will be used when the steam risers and feeders are removed for real.
