Kyle D. Haak’s Dissertation Defense (2022)

Although new and advanced nuclear energy technologies (NETs) could provide reliable electricity and reduce carbon emissions for Department of Defense (DoD) locations, the values of these benefits and the NET’s characteristics, costs, and regulations are uncertain. This dissertation proposes a decision framework to help DoD decisionmakers determine whether an investment in a NET is worthwhile. I developed the framework based on observations from a literature review, a historical analysis of the Army Nuclear Power Program (1954-1978), a site visit to Eielson Air Force Base, and semi-structured interviews with subject matter experts. The steps of the framework articulate why DoD might invest in a NET, characterize each NET of interest, and identify which DoD locations could viably host that NET. The steps also describe how to disclose assumptions, account for uncertainties, and examine risks that could impact an investment in a NET. I scoped the framework to focus on NETs with low power capacities that DoD implements at locations in the United States for the entirety of the NET’s lifespan. I applied the framework to unclassified data to demonstrate how to use it and provide key findings and recommendations to DoD decisionmakers. The framework application showed that few DoD locations have a relative average electricity cost greater than a NET’s levelized cost of electricity and an average power consumption greater than the NET’s power capacity; however, there are some cases (combinations of future scenarios and NETs) with numerous viable location-technology pairs. The data suggests that DoD should abandon the independent pursuit of microreactors with 1-5 MWe power capacity for DoD locations in the United States because the monetary and non-monetary costs are greater than the monetary and non-monetary benefits for DoD. Alternatively, implementing a 17 MWe NET at twenty-one viable DoD locations in the United States may be a worthwhile investment for DoD. Therefore, this dissertation recommends DoD decisionmakers invest in more accurate cost estimates of a 17 MWe NET and perform a more targeted investigation of the twenty-one viable DoD locations.
