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.

Title: Challenges in Large-scale Modeling and Simulation for Nuclear Systems. The increase in affordable computing capacity, in availability of computer codes designed for high performance computing, and in the need for varying levels of solution fidelity for analysis, design and licensing of complex nuclear systems has driven a desire for multi-scale, multi-physics modeling and simulation capabilities and has required dramatic shifts in the size and fidelity of computational models and computer simulations. This roundtable will feature perspectives from both developers and appliers of computer codes for modeling and simulation across a number of nuclear systems. The purpose is to have an application-focused discussion of how the needs of various emerging nuclear applications are driving the development of tools for analysis and design of complex nuclear systems, and the challenges that are emerging.
