EDF, the French energy giant, has decided to revise its plans for the development of its small modular reactor (SMR) named Nuward.
Originally slated for completion around 2030, the company is now working on a new design, confirming information from L’Informé.
Lessons Learned from Engineering and Market Insights
While the project was in the “detailed preliminary design” phase, EDF decided to abandon the initial design based on “lessons learned from engineering work and discussions with market players.”
EDF remains committed to delivering a third-generation SMR with “better conditions for success and technical feasibility,” but has not provided specifics on the revised timeline.
New Design Based on Proven Technologies
The future design will incorporate “technologically proven components,” according to EDF, which established a dedicated subsidiary, Nuward, in early 2023.
The Nuward SMR project was a collaborative effort between EDF, CEA, Naval Group, Framatome, and Tractebel.
Previous Design: Compact and Innovative
The initial Nuward SMR design was intended to be one of the most compact in its category (less than 15 meters in height). It utilized pressurized water reactor (PWR) technology, similar to the existing French nuclear fleet, but with innovations such as steam generators integrated into the vessel.
EDF assures that the future SMR will capitalize on the technical, industrial, and commercial lessons learned from Nuward. It will also leverage EDF’s extensive experience in nuclear power and PWR technology.
SMRs as a Decarbonization Solution
Proponents of SMRs, which are smaller and less powerful than traditional reactors, view them as a solution for decarbonizing energy-intensive industries that rely on fossil fuels.
There are over 80 SMR projects identified worldwide. In France, the first official authorization request was submitted in April by the French startup Jimmy.
In 2023, nine innovative reactor projects, including Nuward, were included in the “France 2030” investment program.
