Abstract

While nuclear reactor design is recognized as an essential skill and intellectual output of academic nuclear engineering, little attention has been paid within the discipline to the structure of the reactor design process and how factors beyond physical constraints influence design outcomes. In this talk, I describe the first systematic exploration of the nuclear reactor design process through the application of methodological and theoretical tools developed within the mechanical engineering design research field. Empirically based on a study of 27 American and 5 French contemporary reactor projects, this work examines how reactor designers make decisions in the early foundational stages of design such as conceptualizing the available design space and making design choices around cost, safety, and performance. The findings of this study reveal that the structure of the design process and its outcomes are significantly shaped by the identity and expertise of the designer as well as the site of the design work.

They also highlight the importance of social determinants of design outcomes particularly in the early, critical stages of design, and point to the need for a richer understanding of the reactor design process that goes beyond the long-held view focused on engineering analysis as propounded in nuclear engineering pedagogy. A deeper comprehension of these determinants of design outcomes is likely to yield valuable insights for design practice, pedagogical purposes, and chiefly for the creation and implementation of policies in the nuclear energy sector. In closing the talk, I will briefly describe some of these future research directions.

Positron emission tomography (PET) is a widely used medical imaging technique, and like many other tomographic imaging modalities, relies on an image reconstruction step to produce cross-sectional images. Detection and localization of the back-to-back annihilation photons produced by positron-electron annihilation defines the trajectories of these photons, which when combined with tomographic reconstruction algorithms, permits recovery of the spatial distribution of positron-emitting radionuclides.  Time-of-flight information, typically at the level of 200-400 ps in modern PET systems is used to constrain the reconstruction process. Once the time-of-flight resolution is improved by an order of magnitude to ~30 ps, a new regime is encountered where radioactive decay events can be directly localized without the need for tomographic reconstruction. In this presentation we show how prompt Cherenkov luminescence, photodetectors with very fast single photon response times, and deep-learning based timing pickoff algorithms are combined in an ultra-fast radiation detector to achieve a timing resolution of 32 ps, localizing positron-electron annihilation sites to 4.8 mm.  We also show this is sufficient to directly generate a cross-sectional image of positron-emitting radiotracers.

Simon R. Cherry, Ph.D. received his B.Sc.(Hons) in Physics with Astronomy from University College London and a Ph.D. in Medical Physics from the Institute of Cancer Research, University of London. He is currently Professor in the Departments of Biomedical Engineering and Radiology at the University of California, Davis. Dr. Cherry’s research interests focus on the development and application of biomedical imaging systems. Dr. Cherry is a fellow of six professional societies and served as Editor-in-Chief of the journal Physics in Medicine and Biology from 2011-2020.

The 2011 Fukushima Dai-ichi Nuclear Power Plant accident serves as an example of the risks associated with energy technologies and the need to minimize physical as well as psychological effects on local and global communities. We have established the RadWatch and DoseNet community outreach programs to enhance the public understanding of risks associated with radiation exposure. The RadWatch program works to provide transparent, relevant measurements of radioactivity in our environment through measurements of locally sourced fish and produce. The ongoing monitoring of radiation in our environment provides the public with a clear baseline for what is “normal”. This work has since been expanded to include the use of neutron activation analyses to determine the concentrations of heavy metals in such samples, further contextualizing previous radiological measurements and our environmental impact. Similarly, the DoseNet project was developed to bring radiation and environmental data into classrooms and connect directly with students. DoseNet is a network of radiation and environmental sensors connecting schools in the Bay Area, Japan, and around the world. The DoseNet program has used this network to recruit a handful of high school students each summer as interns. These programs represent parts of a multidisciplinary undertaking to educate the next generation about radiation science, improve scientific literacy, and improve our communication of technical concepts to our communities.

Ali Hanks is a Lecturer and Project Scientist in the Department of Nuclear Engineering at the University of California, Berkeley. Her research is focused on advancements in radiation detection and imaging  technologies. As head of the RadWatch and DoseNet outreach programs, a large part of her work focused on the applications of advanced radiation detection technologies towards public education and outreach. Dr. Hanks received her Ph.D. in High Energy Nuclear Physics from Columbia University as part of the PHENIX collaboration. She spent 4 years as a Postdoctoral Fellow at Stony Brook University, and then at UC Berkeley where she had a joint Postdoctoral position in the Physics and Nuclear Engineering departments. She has been an Assistant Project Scientist in the Department of Nuclear Engineering since 2017, and has worked as a Lecturer the last three years teaching a new course she designed based on her work with students in the DoseNet program.
