As set out in January's White Paper on Nuclear Power, the Justification process is a necessary step to meet the requirements of EU regulation to ensure that the benefits and detriments are properly evaluated before new nuclear power stations can be built in the UK.

To ensure the Justification process is effective, fair and open, the Department for Business is issuing a specific call for applications within a specific timeframe to make it easier for applicants and regulators alike.

Multiple nuclear reactor designs offering similar benefits and detriments could be assessed as part of a single application.

Business Secretary, John Hutton said:
"The Justification Decision is the first major regulatory stage for new nuclear reactors, and an important step towards the construction of new nuclear power stations in the UK.

"The process is designed to be fair, transparent and robust, but also as efficient as possible, easing unnecessary burdens for the energy industry, the Government and regulators.

"New nuclear power has the potential to help tackle climate change and secure future energy supplies as part of the UK's energy mix. Momentum is building and it is important this is maintained by taking the necessary steps to reduce the regulatory and planning risks facing investors."

It is thought the Justification process, including a formal consultation, will take around 18 months to complete.
