The nuclear waste problem is defined and analyzed from a systems engineering viewpoint. Problem magnitude and systems context are discussed. Requirements for a waste repository are presented and the current progress of the repository is noted. The Department of Energy's waste disposal system including repository site selection, monitored retrievable storage facility, and waste transportation system is analyzed. A description of nuclear fuel reprocessing is given. The potential benefits and risks of reprocessing are addressed including economic feasibility and environmental issues. A framework for systems analysis of the problem is presented. Four recommendations for further systems analysis are presented: 1. An unbiased systems analysis of the Yucca Mountain proposed repository including indirect political, social and economic aspects. 2. A systems engineering backing of the monitored retrievable storage facility 3. Development of rail transportation guidelines for nuclear waste 4. An economic analysis of the feasibility of spent fuel reprocessing to include indirect costs / Master of Engineering

The disposal of waste is a growing environmental, political, and economic problem. Low level radioactive waste (LLW) disposal is no exception. The major purposes of this dissertation are to examine the economic tradeoffs which arise in the process of LLW disposal and to derive a framework within which the impact of these tradeoffs on LLW disposal policy can be analyzed. There are two distinct stages in the disposal of LLW--the transportation of the waste from sources to disposal sites and the disposal of the waste. The levels of costs and risks associated with these two stages depend on the number and location of disposal sites. Having more disposal sites results in lower transportation costs and risks but also in greater disposal costs and risks. The tradeoff between transportation costs and risks can also be viewed as a tradeoff between present and future risks. Therefore, an alteration in the spatial distribution of LLW disposal sites necessarily implies a change in the temporal distribution of risks. These tradeoffs are examined in this work through the use of a transportation model to which probabilistic radiation exposure constraints are added. Future (disposal) risks are discounted. The number and capacities of LLW disposal sites are varied in order to derive a series of system costs and corresponding expected cancers. This provides policymakers with a cost vs. cancers possibility function. The marginal cost of reducing cancers by changing the number and location of disposal sites is calculated. A possible policy application of this information is illustrated by comparing these costs to an assumed value of life derived from experimental evidence found in the literature. A tentative conclusion is reached that the current movement toward a system of regional LLW disposal sites may be economically suboptimal.
