Tennessee senators call on Trump to “rescue TVA from itself”
Hagerty
Blackburn
In a strongly worded opinion piece published by Power Magazine on March 24, Tennessee Sens. Marsha Blackburn and Bill Hagerty call for new leadership at the Tennessee Valley Authority to jumpstart its small modular reactor program.
The GOP lawmakers are looking to President Donald Trump and Energy Secretary Chris Wright to overhaul TVA’s board of directors to drive America’s role in the nuclear renaissance. TVA is the first and only U.S. energy company to obtain an early site permit for a small modular reactor, but the utility has not progressed on physical deployment of a unit since the permit was awarded in 2019.
Chicago-Great Lakes Local Section Event
February 27, 2025|6:00–7:00PM (7:00–8:00PM EST)
Available to All Users
Join the ANS Chicago-Great Lakes Local Section for a presentation on the advancements in nuclear energy through the Molten Salt Research Reactor (MSRR) project at Abilene Christian University (ACU).
The presentation will focus on the MSRR's critical role in addressing global challenges, the advantages of using molten salt as a medium for energy production, safety features, the development timeline, key milestones, and future prospects for both Molten Salt Reactors (MSRs) and Small Modular Reactors (SMRs). The presentation will be followed by an interactive Q&A session into the MSRR's potential impacts on society and the environment.
Please register for this hybrid event and indicate whether you will be attending virtually or in person at the ANS Headquarters office (1111 Pasquinelli Dr., Suite 350, Westmont, IL 60559).
About the PresenterLester Towell, Director of Operations, ACU NEXT Lab, earned his bachelor’s degree in Engineering Physics from Abilene Christian University in 1990. For the next four years, he served in the US Navy as an instructor at the Naval Nuclear Power School in Orlando, FL where he taught Reactor Principles and Physics. In 1995, Towell joined the Computer Information Systems department at Howard Payne University and moved to the Nuclear Energy eXperimental Testing (NEXT) Lab at ACU in 2020 as the licensing manager for the first university advanced reactor in the country.
