As long as nuclear weapons exist, the United States will maintain a safe, secure and effective nuclear deterrent to keep America safe. In support of this presidential mandate, the Energy Department -- specifically the National Nuclear Security Administration (NNSA) -- is responsible for ensuring the integrity and safety of the nation’s nuclear weapons, advancing nuclear nonproliferation and promoting international nuclear safety.
We also work with industry partners to model risks to privately owned U.S. nuclear facilities from cyber attacks and support climate change adaptation efforts to prevent overheating of nuclear reactors, an increasing threat as global temperatures rise and droughts become more common.
