Abstract: The British, American, French and Finnish governments are seeking to promote investment in a new generation of nuclear power plants. Nuclear power programmes are delivered through networks of international companies through which government must manage. This is consistent with the concept of governance. Governments can advance their policy goals by using a variety of policy instruments to shape and organize governance networks. This is known as metagovernance. The paper considers the extent to which the selection and deployment of the policy instruments used to metagovern is informed by the prevailing tradition of government. The paper examines how the British, American, French and Finnish governments have tried to metagovern. It is shown that whilst governing traditions do inform the selection and deployment of the policy instruments used to metagovern, the composition of the network, and the nature of the policy problem also plays a role in shaping government action.
