President Trump’s nuclear tests will use non-explosive methods, not detonations, U.S. Energy Secretary Chris Wright confirmed.

Energy Secretary Chris Wright confirmed on November 2, 2025, that President Donald Trump’s announced nuclear weapons testing plans will not include actual nuclear explosions. Instead, the tests will use non-nuclear methods such as simulations, subcritical experiments, and component evaluations to assess the reliability and safety of the U.S. nuclear arsenal. Wright emphasized the tests are consistent with the U.S. moratorium on nuclear detonations since 1992 and do not signal a reversal of longstanding non-proliferation policies. The clarification followed Trump’s social media post suggesting plans to begin testing, which sparked international concern. Officials stressed that the U.S. maintains a credible deterrent through stockpile stewardship programs, and no explosive tests are currently scheduled.
