1. Lartonoix, David. Radioisotope Inventory Of Spent Nuclear Fuel In Mathematica.

Degree: MS, 5183, 2012, University of Illinois – Urbana-Champaign

While nuclear reactors in the United States have produced economy-driving power for several decades, they have also left behind a significant amount of spent nuclear fuel. The federal government, ultimately responsible for this spent fuel, has a history just as long in attempting to effectively bury, dispose, reprocess, or otherwise deal with this waste. As no attempts to date have been entirely successful, work continues to find an effective waste management solution. To aid planners, policymakers, and scientists in this endeavor, tools are currently needed to model the radioisotope inventory of all spent nuclear requiring disposal or other forms of remediation to accurately frame the scope of the issue. This project describes a simple method of calculating radioisotope concentrations in spent fuel by utilizing a unique approach to solving the diffusion equation eigenvalue problem. Herein, the dissolved boron concentration, essentially a chemical shim, is adjusted over an operational time period to maintain criticality in the reactor, compensating for fuel burnup, burnable poison burnout, and actinide and fission product buildup. It is shown, as an example, that the fractional reduction in boron concentration after a month of reactor operation is 2.3%. The normalized neutron flux in the example scenario is calculated and confirmed to be relatively flat radially and vertically. Similarly, the normalized thermal energy production rate is also shown to be relatively flat, as expected. Radionuclides of interest are tracked and isotopic concentrations are shown at various vertical heights within the core. Upon further refining, these concentrations can be taken to represent the radioisotope inventory of spent nuclear fuel under various burnup scenarios. Ultimately, characterizing the spent fuel requiring disposal will aid in developing an efficient waste management strategy. Even while several shortfalls are noted and described, tools such as this computer code can play a useful role in addressing the nation's nuclear waste disposal dilemma. Advisors/Committee Members: Singer, Clifford E. (advisor).

2. Geringer, Robert Jeffrey. Preliminary design and analysis for selected problems in deep borehole disposal of spent nuclear fuel.

Degree: MS, Nuclear, Plasma, Radiolgc Engr, 2016, University of Illinois – Urbana-Champaign

Multiple reports by the Used Fuel Disposition Campaign centered at Sandia National Laboratories, Dr. Michael Driscoll and collaborators at MIT, and Dr. Fergus Gibb and collaborators at the University of Sheffield have generated interest in deep boreholes as a nuclear waste disposal option for all or part of the U.S. high-level waste inventory. Many design elements of deep borehole disposal have not yet been solidified, and there has not yet been a systematic analysis of the logistics necessary to implement deep boreholes for the storage of commercial spent nuclear fuel. This thesis contains preliminary analysis on a variety of unanswered or incomplete elements of the deep borehole approach, including emplacement method, disposal region design, canister loading method, transportation and logistics scheduling and cost, and risk analysis for borehole-specific issues. Additionally, the thesis presents an analytical heat transport model which can be used to validate more detailed numerical solutions. The logistics analysis, performed using the TSL-CALVIN fuel cycle logistics simulator, demonstrates that a deep borehole repository can be cost-competitive with a more traditional mined repository approach, but that the differences between mined repositories and a deep borehole repository are large enough that other system-level cost estimates performed for the Yucca Mountain repository might not transfer to a deep borehole repository.

3. Milligan, Tim. Development of an econo-energy model and an introduction to a carbon and climate model for use in a nuclear energy analysis.

Degree: MS, 5183, 2012, University of Illinois – Urbana-Champaign

Modern society has developed an ever increasing demand for energy to fuel population growth, increases in quality of life, and the advancement of third world countries. Currently, we feed our power needs with mostly carbon-based energy sources, which have an appreciable effect on the global climate. To continue advancing, society must develop alternative, low-carbon methods for energy production with both nuclear and renewable sources being complementary contributors. The possible shift to the increased use of alternative and nuclear technology brings with it an ever more pressing need to extrapolate future energy and emission scenarios. The objective of this thesis was to further develop an econo-energy model, the LOGICAL-1 model, and to outline a functional carbon and climate model for prototyping the economic and environmental impact of potential political scenarios. Projections of future population growth, carbon intensity, carbon usage, and energy usage were developed, and the results predicted a quadrupling of energy use and carbon use by the end of the twenty-first century. To determine the potential environmental ramifications, a basic climate and carbon model was developed and initially benchmarked against historical atmospheric carbon-dioxide concentration and temperature data. The results from the climate model predicted a 1C warming over the globally averaged surface temperature relative to 1990 AD and a doubling of the atmospheric carbon dioxide concentration by the end of the twenty-first century. The first targeted use of the LOGICAL-1 and climate-carbon model is to help determine the amount of future spent nuclear fuel that could potentially be accumulated during the twenty-first century based on arbitrary political and environmental scenarios. The basic outline for a spent nuclear fuel analysis is included. Advisors/Committee Members: Singer, Clifford E. (advisor), Roy, William R. (advisor).
