MIXED WASTE

NSSI services and supports the government, industrial, radiopharmaceutical, and education sectors. NSSI is a fully licensed and permitted to accept, store, and treat all mixed wastes including special nuclear materials.
Waste containing both radioactive and hazardous constituents has been generated since the beginning of the commercial nuclear industry. This waste has come to be known as mixed waste. When the first Federal regulations covering radioactivity were adopted, they were intended to apply to all radioactive materials, without consideration of other hazardous characteristics. During the early 1980s, State and Federal agencies began to question generators and site operators regarding mixed wastes and compliance with the requirements of RCRA. By 1985, as a result of public and congressional attention, radioactive/hazardous mixed wastes were addressed as a part of the LowLevel Radioactive Policy Amendments Act (LLRWPAA) of 1985. In 1988, the EPA assumed regulatory control of mixed waste storage and treatment facility (TSDF) permitting. Mixed wastes are now subject to joint control by the NRC/Agreement States and EPA.

TREATMENT

NSSI accepts a full spectrum of hazardous and radioactive waste materials including all D, F, P, U and K hazardous waste codes and all radionuclides, including special nuclear materials. NSSI treats gases, liquids, solids, sludges, and soils. NSSI also accepts and treats recyclables, such as chlorofluorocarbons, solvents, mercury compounds, mercury contaminated substances and fluorescent tubes.

PERMITS

NSSI is unique in that the facility permits allow storage and treatment of RCRA hazardous, mixed hazardous/ radioactive and radioactive waste materials. NSSI operated as an interim status Waste Treatment and Storage facility from 1980 to 1990. NSSI subsequently submitted the required Part B application and received a final Part B permit in October, 1990. Permit modifications are requested on an ongoing basis as new treatment technologies are proven and commercialized and as additional facilities are needed.

MIXED WASTE GENERATION

Mixed waste generation studies have indicated that 3-10% of all Low Level Radioactive Waste is mixed waste containing both radioactive and chemical constituents. Mixed wastes are generated by many industrial, medical, and educational facilities.

TRITIUM RECOVERY METHODS

NSSI conducts innovative research on tritium recovery methods that are robust, scalable and applicable to diverse sources including:

  • Carbon/Molecular sieve traps
