To ask the Secretary of State for Business, Energy and Industrial Strategy, pursuant to the Answer of 27 April 2018 to Question 136693 on Wylfa Power Station: Construction, if he will publish the criteria by which the process of regulatory justification assessed the (a) reliability, (b) costs, and (c) implications for energy security of the use of advanced boiling water reactors in the UK, including at the new nuclear power station at Wylfa Newydd, Wales.
Regulatory Justification represents the process of considering the benefits of a particular class or type of practice in light of the potential health detriments associated with it.
The types of practices covered by this process vary significantly and the comparison of benefits and detriments is dependent on the nature of the practice being considered. Applicants are expected to appraise the benefits and detriments associated with their proposed activity and these applications are scrutinised by Government prior to making a justification decision.
Consideration of energy security, including reliability, and other economic effects associated with the UK ABWR is set out in Chapter 5 of the Regulatory Justification decision. In considering these aspects, my rt. hon. Friend the Secretary of State took account of the application, views expressed as part of public consultations on both the application and proposed decision and relevant Government policy at the time.
