Nuclear Energy and the Non-Proliferation Treaty: A Retrospective Examination

ABSTRACT This commentary looks at how nuclear power has evolved in the last five decades since the Treaty on the Non-Proliferation of Nuclear Weapons entered into force in 1970. Using data on numbers of reactors constructed around the world, we show that the early expectations of a rapid growth of nuclear power plants around the world has not materialized. We also outline the trends in safeguards at nuclear facilities, namely the measures undertaken to prevent the diversion of fissile materials for use in nuclear weapons, and highlight the potential risks due to the rapid growth in the amount of material that could potentially be diverted.
