NSSI
The five fundamental areas of our organization are Tritium Recycling, Sealed Sources, RCRA Waste, Mixed Waste, and Low Level Radioactive Waste.
NSSI offers services and products including chemical and radioactive decontamination, leak testing, radiation instrument calibration, radiation safety training, and waste disposal. NSSI continues to strive on an upward trajectory toward success with a vigorous emphasis on recycling, waste minimization, clean treatment/disposal options and waste management methods incorporating a strong value on being eco-friendly by providing our services in a clean, safe, and environmentally friendly approach. NSSI has been permitted and licensed for the manufacture, use, collection, treatment, disposal, storage, transfer, servicing of radioactive sealed sources, radioactive materials, hazardous mixed waste, and hazardous/non-hazardous chemicals. NSSI currently holds Texas Radioactive Materials Licenses LO-2991 and RO-1811. The company obtained its final part B permit # HW-50269 by the Texas Commission of Environmental Quality in 1990 and its EPA TXD982560294 to receive a broad spectrum of waste. Our extensive licenses afford us the ability to provide a wide range of services to our customers that otherwise may be hard to perform within the constraints of their existing licenses.
