The Common Assembly proposed extending the powers of the European Coal and Steel Community to cover other sources of energy. However, Jean Monnet, ECSC architect and President, wanted a separate community to cover nuclear power. Louis Armand was put in charge of a study into the prospects of nuclear energy use in Europe; his report concluded that further nuclear development was needed to fill the deficit left by the exhaustion of coal deposits and to reduce dependence on oil producers. However, the Benelux states and Germany were also keen on creating a general single market, although it was opposed by France due to its protectionism, and Jean Monnet thought it too large and difficult a task. In the end, Monnet proposed the creation of separate atomic energy and economic communities to reconcile both groups. The Intergovernmental Conference on the Common Market and Euratom at the Château of Val-Duchesse in 1956 drew up the essentials of the new treaties. Euratom would foster co-operation in the nuclear field, at the time a very popular area, and would, along with the EEC, share the Common Assembly and Court of Justice of the ECSC, but not its executives. Euratom would have its own Council and Commission, with fewer powers than the High Authority of the European Coal and Steel Community. On 25 March 1957, the Treaties of Rome were signed by the ECSC members and on 1 January 1958 they came into force. To save on resources, these separate executives created by the Rome Treaties were merged in 1965 by the Merger Treaty. The institutions of the EEC would take over responsibilities for the running of the ECSC and Euratom, with all three then becoming known as the European Communities even if each legally existed separately. In 1993, the Maastricht Treaty created the European Union, which absorbed the Communities into the European Community pillar, yet Euratom still maintained a distinct legal personality. The European Constitution was intended to consolidate all previous treaties and increase democratic accountability in them. The Euratom treaty had not been amended as the other treaties had, so the European Parliament had been granted few powers over it. However, the reason it had gone unamended was the same reason the Constitution left it to remain separate from the rest of the EU: anti-nuclear sentiment among the European electorate, which may unnecessarily turn voters against the treaty. The Euratom treaty thus remains in force relatively unamended from its original signing.
EU evolution timeline
This overall timeline includes the establishment and development of Euratom, and shows that currently it is the only former EC body that has not been incorporated into the EU.
Since 2014, Switzerland has participated in Euratom programmes as an associated state.
The United Kingdom announced its intention to withdraw from the EAEC on 26 January 2017, following on from its decision to withdraw from the European Union. Formal notice to withdraw from the EAEC was provided in March 2017, within the Article 50 notification letter, where the withdrawal was made explicit. Withdrawal only became effective following negotiations on the terms of the exit, which lasted two years and ten months. A report by the House of CommonsBusiness, Energy and Industrial Strategy Committee, published in May 2017, questioned the legal necessity of leaving Euratom and called for a temporary extension of membership to allow time for new arrangements to be made. In June 2017, the European Commission's negotiations task force published a Position paper transmitted to EU27 on nuclear materials and safeguard equipment , titled "Essential Principles on nuclear materials and safeguard equipment". The following month, a briefing paper from the House of Commons Library assessed the implications of leaving Euratom. In 2017, an article in The Independent questioned availability of nuclear fuel to the UK after 2019 if the UK were to withdraw, and the need for new treaties relating to the transportation of nuclear materials. A 2017 article in the New Scientist stated that radioisotope supply for cancer treatments would also need to be considered in new treaties. UK politicians speculated that the UK could stay in Euratom. In 2017, some argued that this would require – beyond the consent of the EU27 – amendment or revocation of the Article 50 letter of March 2017. The Nuclear Safeguards Act 2018, making provision for safeguards after withdrawal from Euratom, received royal assent on 26 June 2018.
In the history of European regulation, Article 37 of the Euratom Treaty represents pioneering legislation concerning binding transfrontier obligations with respect to environmental impact and protection of humans.
Presidents of the EAEC
The five member Commission was led by only three presidents while it had independent executives, all from France:
