The transformation of the NRC: 50 years of commissioners
The dust is beginning to settle following the whirlwind of changes at the Nuclear Regulatory Commission over the past year, and 2025 ultimately may be viewed as a transformative year, as well as the year the NRC celebrated its golden anniversary. The 12 months of that milestone year brought more change to the agency in its composition, its mandate, and its relationship to the executive branch than any comparable period in the preceding four decades.
Now at 51 years and counting, the NRC is working with a full commission and issuing new rulemakings to both regulate and support the next round of nuclear deployments. With the turbulence of 2025 still fresh in our minds, Nuclear News decided it was a good time to revisit the professional backgrounds of all 42 NRC commissioners who have served over the agency’s 50-year history to see how the composition of the commission has evolved over time.

A model for steam condensation in the presence of non-condensable gases is developed in the CFD package ANSYS CFX 16.1. Based on the Euler-Euler two-fluid approach, this model considers two different phases: a continuous gas phase, which is a mixture of air and steam, and a disperse liquid phase consisting of water droplets. Using the data of the CONAN test facility, the numerical error is quantified using the Grid Convergence Index method. The simulation results are then validated using the experimental data of the CONAN test facility. Finally, the applicability of the condensation modeling in the model containment THAI+ is tested.
