Natalie Cannon is passionate about nuclear policy
Some people are born leaders, and some people make themselves leaders. Take Natalie Cannon, a fourth-year doctoral candidate in the Department of Nuclear and Radiological Engineering and Medical Physics at the Georgia Institute of Technology. She has been driven to succeed since she was a teenager in Southern California, when she was inspired by NASA’s Mars Exploration Program.

Radioactive waste-handling operations at a potential high-level radioactive waste (HLW) geologic repository at Yucca Mountain, Nevada, would involve receiving, processing, aging, and emplacing HLW equivalent to 70 000 t of heavy metal. This paper presents results of an independent analysis of the external radiation dose fields for various designs at a potential repository underground facility, performed at the Center for Nuclear Waste Regulatory Analyses. In order to analyze dose fields, radiation source terms have been developed for commercial spent nuclear fuel (SNF) assemblies. Full-scale three-dimensional models of waste packages and underground repository drifts were used in the Monte Carlo radiation transport simulations. Radiation dose rates along the drifts have been evaluated for multiple waste packages for SNF-emitted photons, neutrons, and 60Co photons. Analysis shows that SNF photons contribute >68%, 60Co photons contribute <30%, and neutrons contribute <2% to the total dose rates. The contribution of photons scattered off the drift walls is <10% of the total dose rates. The drift elbow significantly blocks direct radiation shine and reduces scattered dose rates at the junction of turnout and main access drifts where workers could be present.
