Studsvik offers treatment of low level metallic waste at its own facilities in Studsvik outside Nyköping in Sweden, in Memphis, Tennesse in the US, and in Workington in the UK.
Studsvik is the largest supplier of large nuclear component processing and disposal services in the United States. Over the past five years, Studsvik has successfully processed and recycled and/or disposed of over 12,000,000 pounds of large nuclear components at its Memphis, Tennessee, processing facility. Services provided by Studsvik include "turnkey operations" including the supply of characterization service, packaging, lifting, transporting, processing and recycling or disposing of a wide variety of large components.
Studsvik employs the largest components decontamination chamber in the United States at its Memphis radioactive materials processing facilities and is the only processor that has successfully transported, processed and disposed of a commercial nuclear reactor pressure vessel head with CRDMs attached.
Studsvik's facility in Sweden melts metal scrap, such as stainless steel, carbon steel, copper, aluminium or lead. Melting reduces the volume and weight of the waste, resulting in reduced costs for interim on-site storage and final disposal. The end-product is metal ingots, which can either be immediately free-released as conventional scrap metal or released after a period of decay storage. Residual products (slag, sorted material, cutting and blasting residues and dust from the ventilation filters) and ingots that cannot be free-released are returned to the customer.
Scrapped large components present a challenge since, due to their size, the disposal of whole components in a repository is usually very expensive and complicated. Since the 1990's Studsvik's facility in Sweden has successfully treated over 10,000 metric tonnes of low-level radioactive components such as turbines, pre-heaters, moisture separators and heat-exchangers, to reduce the volume of the waste and save storage and final disposal costs.
Studsvik has developed a unique process for treating steam generators where special methods are applied to treat and reduce the volume of the highly radioactive tube bundle.
