2025: The year in nuclear
As Nuclear News has done since 2022, we have compiled a review of the nuclear news that filled headlines and sparked conversations in the year just completed. Departing from the chronological format of years past, we open with the most impactful news of 2025: a survey of actions and orders of the Trump administration that are reshaping nuclear research, development, deployment, and commercialization. We then highlight some of the top news in nuclear restarts, new reactor testing programs, the fuel supply chain and broader fuel cycle, and more.

Thoria rods and a water moderator are arranged in a simple rectangular geometry in a multilayered configuration to produce 233U by bombardment with 14-MeV neutrons. The 233U production rate is measured by measuring the 312-keV gamma activity associated with 233Pa. Detailed neutronic calculations have been made using the versatile MCNP Monte Carlo code and the BMCCS2 cross-section library. There is very good agreement between the experimental measurements of 233U production and the corresponding calculations.
