Although the first quarter of the year saw some of the French nuclear fleet return to service, it was not at the rate originally anticipated, according to data analysis company EnAppSys. France’s nuclear availability, the company noted, was expected to reach a maximum of 50 GW by the middle of the first quarter, but that goal was not reached due to several reasons, including the need for additional repairs and maintenance when stress corrosion cracking first appeared in several reactors last year. Workforce strikes at nuclear operator Électricité de France also led to widespread employee walkouts from nuclear power plants.
