One month into my term as president of the American Nuclear Society, it is already clear that the nuclear field continues to move quickly. June alone brought a striking number of developments, each one pointing to the momentum of this moment.
Antares’s Mark-0 microreactor reaching criticality at Idaho National Laboratory was more than a technical milestone. It effectively brought reactor No. 53 on line at a site that has shaped much of the nation’s nuclear history, with 52 reactors built there since 1951. And more criticality starts were delivered in June and July, enabled by the Department of Energy and its partnerships with private companies.
At the same time, the Nuclear Regulatory Commission is continuing its broad regulatory reform effort, and nuclear technology is being used to help combat an outbreak of New World screwworm that has spread to the United States.

Advanced high temperature gas cooled reactors typically rely on high pressure gas flows for heat removal during normal operations and a mix of natural convection, radiation and conduction for heat removal under postulated accident conditions. The combination of high heat capacity structures, relatively low power density, high Prandtl number low-density coolant, and multiple heat removal mechanisms offers significant advantages in terms of passive safety. However, this combination also requires the careful development, verification, and validation of experimental facilities, models and analysis tools that must accurately describe a wide range of flow conditions and heat transfer phenomena. This session provides an opportunity to review current efforts in modeling, simulation or experiments and identify current challenges and opportunities associated with the thermal hydraulics of these systems.
