Encourage fleet approaches in National Policy Statement EN-7
Encourage fleet approaches in EN-7
DESNZ should amend EN-7 to include a statement that where adverse effects arise as a result of the adoption of a fleet approach, the adverse impact will not be a basis for refusal unless exceptional circumstances apply. It is critical that this position is not diluted through additional hurdles.
The policy should expressly state that there is very large weight to be attached to the policy of standardisation. The test should make clear that if an adverse impact results from an approach already accepted in a previous application the "starting points" in relation to the CNP should also apply.
Government Response: Fleet criterion for EN-7 confirmed
The Government will introduce a fleet criterion in the next EN-7 update, favouring impact mitigations that do not require functional design changes. This directly supports the Taskforce's vision for standardised fleet deployment of reactor designs. The updated EN-7 will be published for consultation as soon as practicable, with all EN-7 updates to be completed within 12 months. This is a clear acceptance that fleet approaches should be embedded in national planning policy for nuclear.
