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 1.2 m thick zone of blanket tubes is needed for the LIBRA-SP chamber wall to be a lifetime component. The roof should be located at 17 m from the target to be a lifetime component. The depth of the LiPb pool should be 0.6 m for the bottom plate to be a lifetime component. The required biological shield thickness is 2.5 m on the side and 2.6 m at the top. The overall TBR is 1.435 and the overall energy multiplication is 1.18. The diode casing as well as the cathode and anode feed bus-bars are lifetime components. If ceramic insulators are used in the magnet coils, they will be lifetime components. If organic insulators are used, the coils have to be replaced once in the life of the reactor.
