Nuclear Nexus

NNSA’s Office of Defense Nuclear Nonproliferation (DNN) works with the U.S. civil nuclear industry to make U.S.-designed nuclear reactors and fuel cycle facilities more secure, easier to safeguard, more resistant to nuclear proliferation, and more competitive on the international market.  This engagement helps unleash the American nuclear renaissance while also keeping America safe from the threats of nuclear proliferation and terrorism. 

Nuclear Nexus serves as a “one-stop shop” for U.S. companies seeking information or assistance from DNN on export controls, international safeguards, security, and proliferation resistance.
