EnergySolutions and Grundons have been successfully delivering combustible services to LLWR and their clients for four years and have the experience and with the knowledge of the nuclear industry can offer a wide range of treatment options for our clients. EnergySolutions have a long relationship with Grundons bringing our experience with processing nuclear materials for waste incineration at our two-furnace Bear Creek treatment facility in Oak Ridge, Tennesse together with Grundon’s UK incineration expertise and experience. The Grundon facility is a true waste to energy plant producing enough electricity to power 20,000 homes offering full recovery as energy under the Waste Hierarchy. The Facility Grundon’s High Temperature Incinerator, located in Colnbrook, Slough, was the first dedicated clinical incineration facility in the UK and has been repeatedly upgraded and refurbished to comply with regulations and exceed the most stringent European standards. The stepper hearth design furnace processes up to 1.25t/h operating 24 hours per day, seven days a week and primarily accepts plastics, wool, clothing, gloves, rubber, protective gear resins filters, putrescible wastes and oils. Under its Radiological Waste permit it can process up to 25 MBq of alpha-waste per month and 25MBq of beta/gamma per day. Currently customers using the LLWR framework send about 200MBq beta/gamma and 3 MBq alpha waste per month on average under commercial agreements. Small uranium quantities are acceptable for a natural isotope composition. Higher processing levels exist for H3 and C14 wastes. All resultant hearth ash from the process is regulated to produce an exempt VLLW waste which is disposed of to in-house permitted landfill facilities. The facility can process wastes with mixed and single fingerprints easily, as long as the general WAC are fulfilled. With 75m3 buffer storage, wastes are typically treated within 3-4days and reusable boxes or containers are sent back to customers in a short time, once they have passed radiological analysis/survey. Our standardised service to customers is based around the use of wheelie bins as excepted packages for which we have a dedicated and large stock, however we have processed waste in FHISO containers, TC05 containers, IP1 Pactec bags and individual plastic or fibreboard drums. Our loading chamber is 1m3 which allows for large items to be added direct in to the furnace without the need for pre-shredding. Due to the design of the plant there are restrictions on metal packing and large volume of liquid being processed. We also have access to the Active Waste Management Facility operated by Doosan Babcock at Gateshead. By utilising this route we can provide repackaging, sort and segregation, size reduction and decontamination of combustible materials.
