Low Level Waste
Disposal of Low Level Waste (LLW) at commercial sites accounted for about 32% of the LLW disposed during 1994. Commercially disposed LLW is generally divided into five categories:
There are 3 commercial LLW disposal sites in the United States as shown below.
The Department of Energy has issued a quality report - IDB 1996 report - that summarizes data on high and low level wastes.
Low level wastes would include discarded construction wastes, resins, clothing, tools, and equipment that generally have low radioactivity levels. Such waste could be generated during operation or decommissioning of a facility. The following figures and tables from the referenced DOE report provide insight into the nature of the low level waste storage issue.
To put low level waste in perspective-if all of the waste from the commercial sites were combined, it would occupy an area ~2300 ft x 2300 ft x 10 foot high. On the basis that a typical city block is 100,000 ft2.This corresponds to an area the size of 53 city blocks. For comparison, the State of Minnesota Pollution Control Agency currently has licensed 27 open sanitary landfills and 24 demolition landfills having a total capacity of ~1160 city blocks. The size of the landfill for accommodating all low level radioactive waste to date throughout the country would be about 1.5 times the average small city sanitary landfill size. It is important to note that this area would cover all commercial waste from the 5 sources listed above.
Utilities are the major generators of low level waste. The cost of storing low level waste has become very expensive. As a result, most utilities have initiated programs to limit waste generation. In addition, a lot of waste may be stored on-site at the plants.
Currently waste can be shipped only to Barnwell, South Carolina, Richland, Washington, and Clive, Utah (as shown in the figure above). In 1982, Congress passed a law that required that all states join regional compacts for the purpose of siting low level radiactive waste storage landfills.
