This report presents a management plan and a technical program plan for the National Waste Terminal Storage (NWTS) program. It was prepared by the Office of Waste Isolation (OWI) which is part of Union Carbide Corporation-Nuclear Division (UCC-ND). These plans are based on guidance provided by the Energy Research and Development Administration (ERDA). The technical plan is an extension of over 15 years of studies of waste storage in geologic formations.

The foundation for work related to nuclear waste management is laid by laws and outlines e.g. the responsibilities of the reactor owners and the state, as represented by the authorities. The Swedish Nuclear Fuel and Waste Management Company (SKB), as well as Posiva Oy in Finland, were set up by the reactor owners in the respective countries in response to the responsibilities of planning, conducting research and to implement the physical structures leading to a safe management of nuclear wastes.
