Flamanville-3 reaches full power
France’s state-owned electric utility EDF has announced that Flamanville-3—the country’s first EPR—reached full nuclear thermal power for the first time, generating 1,669 megawatts of gross electrical power. This major milestone is significant in terms of both this project and France’s broader nuclear sector.

Measurements of the fission-product gas pressure in UO2 fuel elements during irradiation have shown that a significant amount of gas is released during power transients. The gas appears to he released as the element power is decreased to zero during reactor shutdown; little release occurs as the power is raised at startup. It is postulated that gas trapped in bubbles or in a central void is released by cracking or stress-induced movement during the power transient.
