U.S. nuclear capacity factors: Ideal for data centers?
Baseload nuclear generation doesn’t get the respect it deserves, if you ask nuclear operators. But the hyperscale data centers that process our digital lives—like the one right next to the Susquehanna plant in northeastern Pennsylvania—are pushing electricity demand up. Clean, reliable capacity now looks a lot more valuable.

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.
