An interim assessment of progress in implementing these targets and other Plan objectives will be made at the end of 2013 before a full assessment at the end of 2015. For the future, plants will not be approved unless they meet Generation 3 safety standards which notably require passive cooling equipment. This will have a major impact on the nuclear programme as 14 of the 25 planned plants were only compliant with Generation 2 safety standards. Moreover, plants will only be built at coastal locations, meaning that work on 12 planned reactors will cease.
