Chile is a signatory of the nuclear Non-Proliferation Treaty (NPT) and has signed and ratified the Comprehensive Test Ban Treaty (CTBT). It is one of the 44 listed countries needed to sign and ratify for the CTBT to enter into force.

In February 2007 Chilean legislators agreed to commission a number of feasibility studies into utilising nuclear power for electricity generation in Chile. These will take an estimated five years to complete.

Chile is also a member of the Treaty for the Prohibition of Nuclear Weapons in Latin America and the Caribbean (the Tlatelolco Treaty).
