RADIOACTIVE WASTE TREATMENT
NSSI has collected, compacted, treated, and shipped radioactive waste to offsite facilities for disposal since 1971. NSSI is permitted for a full spectrum of radionuclide including special nuclear material (SNM). Radioactive  waste is received, treated, repackaged and shipped for land disposal or incineration at offsite facilities. As needed, NSSI can provide personnel and equipment to aid in the packaging and transport of radioactive waste materials at customer sites. 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.

HAZARDOUS WASTE TREATMENT
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. NSSI accepts many specialized chemical wastes such as Mercury and freons for recycling and reuse. NSSI can provide full hazardous waste services including on-site lab packing and labeling, transport, treatment, and final disposal.

MIXED WASTE TREATMENT
Wastes containing both radioactive and hazardous constituents are referred to as mixed wastes. NSSI is permitted for the acceptance of mixed wastes. Mixed wastes are treated at the NSSI facility to separate the radionuclide from the hazardous component or to treat the hazardous component so that the waste no longer is hazardous. Such separation or destruction, in most cases, will allow the individual components to be disposed as radioactive waste or hazardous wastes at offsite facilities permitted for final disposal.

COMPRESSED GAS TREATMENT
NSSI has 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.

FIELD SERVICES
The application of radioactive tracers and sealed sources in industry is as diverse as industry itself. Radioisotopes allow the tracing of subsurface fluid and gas flow, chemical plant processes, abrasion, corrosion, location of buried pipelines and line stoppage, as well as the measurement of variations in density and chemical content. NSSI provides a knowledgeable and experienced staff to plan, execute, and evaluate all phases of field service projects and to insure that they are conducted safely and in compliance within the regulations of NSSI license and that they provide the information desired by the customer.

DECONTAMINATION
NSSI provides specialized equipment and trained and knowledgeable personnel to perform decontamination of equipment and facilities that may become contaminated with radioactive materials during use or as a result of a radioactive spill. Immediate service for all decontamination procedures is provided by an experienced health physics staff. In addition to the problems associated with the actual cleanup, advice is available on possible legal implications and handling of press releases and other public statements.

Specialized decontamination areas are maintained at the NSSI facility for the decontamination of equipment. High pressure washing, steam cleaning, and other specialized technologies are available to address unusual contamination problems. NSSI's experience with waste and waste disposal assures that all decontamination residues are acceptable for disposal at permitted land disposal sites and treatment facilities.

TRAINING
NSSI provides training in all areas of radiation and hazardous chemical handling. Training programs are specifically designed to meet individual customer requirements. Training can be provided at customer sites or at the NSSI facility.

CONSULTING SERVICES
NSSI offers a complete consulting service to fit the needs of users of radioactive materials, radiation producing equipment, and hazardous chemicals. The consulting service includes, but is not limited to, permit and license assistance, radioactive or chemical handling procedures, facility design, transportation, compliance issues, expert witness, etc.

COMPLIANCE SURVEYS
As NSSI maintains multiple radioactive material licenses and a part B hazardous permit, NSSI personnel must remain abreast of the latest regulations and requirements in both areas. NSSI provides assistance with documentation, record keeping, and permitting for those facilities that wish to utilize third party evaluations of their health and safety programs and assistance with compliance issues. For smaller companies that may not have adequate staff to justify the expense of specific compliance personnel, NSSI can provide competent and experienced personnel and documentation to assure the safe operation of the facility and aid management in insuring that their facility meets all regulatory compliance limits.

WASTE TREATABILITY STUDIES
NSSI's permits to accept and treat radioactive, mixed, and hazardous waste materials allow NSSI to provide waste treatability studies to determine the chemical and mechanical treatments necessary to convert a waste to a form suitable for final disposal. On-site permitted units allow treatability studies for any waste volume.

STORAGE AND DECAY
NSSI is permitted for the storage of up to 4000 drums of waste materials including wastes containing radioactive material. For long lived radioactive materials, NSSI can provide storage pending transport to a land disposal site or return to a licensed generator. For short lived radioactives, storage can be provided for decay of the radionuclide. The short lived decayed waste is surveyed and transferred to off site permitted disposal facilities for final disposal by incineration or land disposal.

INSTRUMENT CALIBRATION
NSSI provides instrument calibration services for radiation survey and monitoring instrumentation. NSSI maintains a full spectrum of alpha, beta, gamma, and neutron calibration sources traceable to the National Bureau of Standards. Source activities range from micro to multiCurie.
