The combination of local energy resource constraints and the domestic and international environment has led France to decide for a major effort to develop nuclear energy. France began developing nuclear technology in the 1940s，laid the foundations for a nuclear power-centered energy policy in the 1970s and nuclear energy became its main source of energy in the 1980s. During the construction of the nuclear energy system，France adjusted its nuclear energy policy three times，going through deceleration，shutdowns and relaunch，successively. In order to guarantee the security and stability of the nuclear fuel supply chain，France has come to diversify the sources of natural uranium imports and establish a global uranium supply chain，with subsidiaries of Orano engaging in uranium exploration，mining，production and other operational activities in Africa，the Americas，Asia and other regions. In the face of the energy crisis，France，a longtime champion of nuclear power，has now announced a big return to nuclear energy，removing obstacles to the development of the nuclear power sector and promoting its all-round revitalisation，and re-emphasising energy autonomy. Such stance will likely strengthen its cooperation with China in the field of civil nuclear energy and deepen Franco-Chinese relations. The Franco-German divergence on energy may exacerbate the discord of the Franco-German axis and the energy shortage caused by the shutdown of French nuclear reactors may accentuate the electricity supply crunch in Europe in the short term. Still，changes in the EU’s position on nuclear energy is likely to result in enhanced cooperation between France and its European partners in the field of nuclear power.
