WRATS 25/04/11

The UK has a unique problem with nuclear waste. As a pioneer in the nuclear sector in terms of the development of weaponry and of nuclear power a variety of equipment designs were used in the early days, along with unusual materials and much experimentation. The large majority of waste forms can be handled with conventional encapsulation, but a small proportion probably a single-figure percentage can’t. ’But that’s still a large volume and tonnage of waste.’ Known as WRATs (wastes requiring additional treatment) or orphan wastes, these materials are being studied for their suitability to encapsulation in polymer materials.
