The Box Encapsulation Plant project is one of the most important construction projects at the Sellafield Site, the plant will play a vital role in Sellafield’s 100-year clean-up programme by taking nuclear waste recovered from the sites’ original wasteplants and encasing it in concrete so it can be stored in a modern building.
