Operating considerations for LLRW disposal

Low Level Radwaste (LLRW) disposal sites have been in operation, in the United States, for the best part of two decads. The development and operation of these facilities underwent a significant change with the implementation of U.S. Nuclear Regulatory Commission Regulations (10CFR61) and enactment of the Low-Level Waste Policy Act of 1980 (as amended in 1985). The Policy Act would site LLRW disposal facilities in states and regions with hydro-geological conditions that may be less than optimum. In such circumstances, engineered barriers, specialized containers, and innovative procedures, would be required, as a strong preference to simple shallow land disposal. This paper addresses some of the primary considerations involved in the safe and effective operation of a LLRW disposal facility in the United States. The information is derived from operating experience during the past decade
