Nuclear Energy Orderbooks 101: Enabling Cost-Effective Nuclear Deployment in Europe

EU Member States expect to deploy at least 60 GW of new nuclear capacity by 2050 to meet its climate and energy security goals. But without greater coordination, the bloc risks a fragmented rollout of new nuclear energy: duplicated efforts, spiralling costs, underinvested supply chains, and project delays.

A nuclear energy reactor orderbook – a series of standardised, repetitive builds, preferably at a single location – can significantly cut costs, accelerate timelines, and strengthen supply chains and workforce capacity.

This factsheet outlines how nuclear orderbooks can help Member States deliver reliable, costeffective nuclear energy while avoiding the inefficiencies of fragmented deployment.
