ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Isotopes & Radiation
Members are devoted to applying nuclear science and engineering technologies involving isotopes, radiation applications, and associated equipment in scientific research, development, and industrial processes. Their interests lie primarily in education, industrial uses, biology, medicine, and health physics. Division committees include Analytical Applications of Isotopes and Radiation, Biology and Medicine, Radiation Applications, Radiation Sources and Detection, and Thermal Power Sources.

High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3
UWC 2022 speaker
As the Senior Vice President of Plant Solutions, David is responsible for leading the asset enhancement services, technical services, spare parts, instrumentation and controls, digital solutions and the BWR Owners Group product portfolios. His team is responsible for delivering services and parts as well as creating long-term strategies and high-value solutions for the existing installed base and setting the long-term services strategy for the next generation of small modular and advanced reactors. In addition, David has overall responsibility to manage the joint venture business partnership between GE and Hitachi.
In his previous role, David served as the Senior Vice President of Sales, responsible for the global sales, commercial operations and business development for all of GE Hitachi’s new nuclear plant offerings.
Prior to joining the Nuclear Plant Projects team as the International Projects Leader in 2008, David worked for 6 years in Global Nuclear Fuel (GNF) as the Vice President of Customer Projects, Commercial Operations and Marketing, delivering fuel and engineering services to the worldwide BWR fleet. David has 36 years of service with GE, and held many diverse assignments in manufacturing, supply chain, sourcing and operations for GE Energy, GE Aviation, & GE Lighting.
David serves on the board of directors for both Global Nuclear Fuel-Americas and Global Nuclear Fuel-Japan. He is a 3-term member of the U.S. Department of Commerce’s Civilian Nuclear Trade Advisory Committee (CINTAC), was the chairman, from 2015-2017, for the World Nuclear Association’s task force on Nuclear New Build Lesson-learned, and served on the technical advisory board for the Nuclear Alternatives Project’s Preliminary Feasibility Study for Small Modular Reactors and Microreactors for Puerto Rico.
David holds a Bachelor of Science degree in mechanical engineering from Worcester Polytechnic Institute.
