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.

A comparative analysis of the role of various ripple-induced classical transport processes of high-energy alpha particles in International Thermonuclear Experimental Reactor (ITER)-like tokamaks is presented. It is shown that alpha particles escape from a plasma mainly because of collisional, rather than stochastic, diffusion. The poloidal distribution of the alpha wall load in ITER is determined.
