NSSI

NSSI has collected, compacted, treated, and shipped radioactive waste to offsite facilities for disposal since 1971 and is permitted for a full spectrum of radionuclide including special nuclear material (SNM). For sealed radioactive sources, NSSI can provide the design and fabrication of specialized containers for land disposal and accepts sealed sources for consolidation and packaging for land disposal. As needed, NSSI provides personnel and equipment to aid in the packaging and transport of radioactive waste materials at customer sites. 

NSSI accepts a full spectrum of hazardous and radioactive waste materials for on-site treatment and off-site final disposal. NSSI treats solids, liquids, and gases bearing EPA hazardous waste codes as well as non-hazardous and accepts many specialized chemical wastes such as Mercury and Freon for recycling and reuse. NSSI can provide full hazardous waste services including on-site lab packing and labeling, transport, treatment, and final disposal. 

NSSI provides for the treatment and disposal of organic and aqueous chemical waste materials at competitive pricing. While fuel blenders are limited in their selection of wastes for 'fuel' blending to a minimum of 5,000 BTU per pound so that, when blended for burning as 'fuel', the final waste will provide not less than 8,000 BTU per pound. All NSSI blended wastes are sent to commercial facilities permitted for 'incineration' rather than for burning as 'fuel'. As a result, the 'fuel' BTU restriction does not limit the types of solvent and water wastes NSSI accepts for waste blending. NSSI can therefore provide for the blending and incineration of liquid organic solvents and aqueous streams at very competitive pricing.

NSSI allows up to 50% water by weight and does not require that received waste streams meet any minimum BTU content. Aqueous wastes exceeding 50% water content by weight are acceptable with excess water surcharges. Halogen content is not a cost factor below 5% halogen (non-fluorinated) and halogen wastes, including fluorinated wastes, are accepted up to 100% with appropriate surcharges. The solids content of liquid waste is also factors into pricing. With the solids content measured as suspended solids and settled solids. Settled solids are determined by measuring the depth of the solids. Suspended solids are measured by centrifuging a representative sample of the liquid layer. The metals content of liquid waste streams is very important as any metals contained may become an ingredient of the incineration facility's solid, liquid, or gaseous effluent and significantly impact costs and/or eligibility.

To assure that wastes received are in fact the wastes quoted, NSSI requires that a generator complete a waste profile defining all of the parameters of their waste and to support the profile with analytical results or knowledge of the process generating the waste. NSSI compares the received waste to the generator prepared profile.     NSSI has long specialized in the treatment of hazardous compressed gases. NSSI uses a variety of chemical processes to react the gases to form non-hazardous treatment residues. NSSI accepts a full spectrum of compressed gases including those with radioactive constituents.
