Energy Secretary Chris Wright said on Sunday that no nuclear explosions will take place during the nuclear weapons testing ordered by President Donald Trump.

Wright told Fox News the tests are non-nuclear explosions and are intended to assess all the other parts of a nuclear weapon to make sure “they deliver the appropriate geometry” and can set up a nuclear explosion.
