U.S. will test nuclear weapons non-explosively to ensure reliability, officials say, under long-standing moratorium.

U.S. Energy Secretary Chris Wright clarified that President Trump’s order to test nuclear weapons will not involve explosions. The tests will rely on simulations and noncritical experiments to assess reliability, in line with the U.S. moratorium on nuclear testing since 1992. Wright said the move is routine stockpile maintenance, not a policy shift, following global concern over Trump’s post and his recent meeting with China’s Xi Jinping. The administration affirmed the U.S. deterrent remains safe and effective, with no plans for underground detonations.
