No utility or other investor is likely to consider financing a nuclear project without a clear and sustained government commitment to having nuclear power as part of the long-term energy mix. In most cases, a broad political consensus or acceptance of this policy will be required, to give confidence that political and policy support will be maintained for the life of the project. Such government support provides certainty and security for investors. Public acceptance is also vital for a successful nuclear programme. Where nuclear power is part of the national energy strategy, it is the task of government and politicians to lead public debate and contribute to ensuring that the nuclear programme has the confidence of the public at large.
