Nuclear News 40 Under 40—2025
Last year, we proudly launched the inaugural Nuclear News 40 Under 40 list to shine a spotlight on the exceptional young professionals driving the nuclear sector forward as the nuclear community faces a dramatic generational shift. We weren’t sure how a second list would go over, but once again, our members resoundingly answered the call, confirming what we already knew: The nuclear community is bursting with vision, talent, and extraordinary dedication.

A version of the RELAP/MOD2 code has been developed to allow the direct calculation of hydrodynamic piping load histories. The code allows the calculation of piping forcing functions within the same computer run used to evaluate the transient thermofluid conditions. A description of this code, RELAP5-FORCE MOD2 is provided. The accuracy and validity of RELAP5-FORCE MOD2 are demonstrated by comparisons to benchmark test data.
