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 objective of this study is to provide an experimental performance assessment of cement borehole plugs subjected to dynamic loadings. This includes the study of dried-out plugs as well as of plugs that have remained wet throughout the testing period. Literature review indicates lack of quantitative data on plug performance under dynamic loading. Nevertheless, it shows that deep underground structures in competent rocks are safer than surface structures, openings at shallow depth, and openings in fractured rocks, when subjected to earthquakes and subsurface blasts. Flow test results indicate that wet cement seals are less permeable than Charcoal granite. Sealing performance is severely degraded when cement seals are allowed to dry. Dye injection tests show that the flow penetrates uniformly through the wet plugs, but occurs only along the plug/rock interface of the dried-out plugs. The permeability of wet and dried-out cement seals does not change significantly after the application of dynamic loads.
