Nuclear Safeguards and Electricity (Finance) Act 1978
The Nuclear Safeguards and Electricity (Finance) Act 1978 (1978 c. 25) is an Act of the Parliament of the United Kingdom which gave effect to Safeguards associated with the international agreement on nuclear weapons. It also authorised the financing of Drax power station. Background 
The Treaty on the Non-proliferation of Nuclear Weapons was made on 6 September 1976. In an agreement between the European Atomic Energy Community and the International Atomic Energy Agency the UK had a Safeguards Agreement in connection with the Treaty. This Act gave effect to that agreement. Parliament agreed that the Central Electricity Generating Board could use up to £50 million to build the second stage of the Drax power station in Yorkshire.
