NECX debut: Shaping the next era of energy
The sold-out inaugural Nuclear Energy Conference & Expo (NECX) got off to a roaring start in Atlanta, Ga., Tuesday morning with an opening plenary that was a live highlight reel discussing the latest industry achievements.
Starting with a lively promo video that left the audience amped up for Entergy’s CEO and NEI chair Drew Marsh, who welcomed everyone to the event, hosted jointly by the American Nuclear Society and the Nuclear Energy Institute. He spoke to a full house of more than 1,300 attendees, promising a blend of science, technology, policy, and advocacy centered around the future of nuclear energy.

Lead-cooled fast reactor (LFR) technology offers technical benefits such as high temperature operation, virtually no loss of coolant accidents, and operation at atmospheric pressure. Liquid lead is nonreactive with air and water, has a high boiling point, poor neutron absorption, and excellent heat transfer properties. Regardless of substantial advantages, the corrosive nature of liquid lead is a critical challenge in implementing LFR technology. This problem is especially pronounced at higher temperatures (>500°C). These issues have motivated research on materials and sensing capabilities in liquid lead. The University of Pittsburgh has developed a pool-type materials testing facility in international collaboration with universities, national labs, and industry. This new facility is a complement to existing loop-type facilities by being able to confirm corrosion testing results at high temperatures and higher coolant velocities, as well as by providing a large open volume of liquid lead to allow for the versatile testing of sensing instruments. In the design and manufacturing of the new facility, several important factors, such as temperature, oxygen concentration, and fluid velocity, were carefully considered. Successful running of the new testing facility will help industry demonstrate the reliability of structural materials and sensing instruments for LFRs.
