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
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

NRC’s David Wright visits the Hill and more NRC news
Wright
The Nuclear Regulatory Commission is in the spotlight today for three very different reasons. First, NRC Chair David Wright was on Capitol Hill yesterday for his renomination hearing in front of the Senate’s Environment and Public Works Committee. Second, the NRC released its updated milestone schedules according to the Nuclear Energy Innovation and Modernization Act (NEIMA) and the executive orders signed by President Trump last month; and third, as reported by Reuters on Tuesday, 28 former NRC officials have condemned the dismissal of Commissioner Hanson earlier this month.
Renomination: EPW Committee chair Sen. Shelley Moore Capito (R., W.Va.) opened the hearing with a statement praising Wright’s experience and emphasized the urgency of stable leadership at the NRC.
“China is executing a rapid build-out of its nuclear industry,” Capito said. “The demand for clean, baseload power is skyrocketing as we position America to win the AI race.”
Utility Working Conference and Vendor Technology Expo (UWC 2023)
Matt Rasmussen is TVA’s Senior Vice President, Engineering and Operations Support. Matt reports to Tim Rausch, Chief Nuclear Officer.
Rasmussen has 20 years of experience in engineering, maintenance, work control training, and operations management at both boiling water reactor facilities (BWR) and pressurized water reactor (PWR) facilities.
Matt started his career at Browns Ferry in 2002 as a Maintenance Engineer. He served in multiple positions before being promoted to the Shift Manager role in 2009. In 2010, Matt advanced to the Operations Superintendent position and later spent 2 years as the Director of Work Management at the station where he was part of the senior management team that recovered the station from Column 4 and INPO Policy Note 14. Matt transitioned to Sequoyah Nuclear Plant where he led the Maintenance organization prior to being promoted to the Plant Manager and then Site Vice President in 2019.
Matt returned to Browns Ferry as the Site Vice President in October 2020 and most recently led the station through a WANO evaluation resulting in an Exemplary rating – the highest rating awarded in our industry. He is passionate about community engagement and giving back to the communities around our nuclear stations. Matt moved to the Nuclear Fleet Center as the Vice President, Engineering and Operations Support August 2022.
Rasmussen entered into the license class and obtained his Senior Reactor Operator License. He is a graduate of TVA’s Advanced Leadership Program and INPO’s Senior Nuclear Plant Management Program and Senior Nuclear Executive Program. He holds a bachelor’s degree in Mechanical Engineering from Auburn University in Alabama.
