Sizewell B power station in Suffolk has resumed generating electricity after completing a planned maintenance and investment programme, costing £80 million.
This work sets the stage for another 18 months of generation and further investment of more than £300 million in the coming years to enhance reliability and performance.
The recent investment included crucial replacements and routine servicing to ensure efficient power generation.
Experts conducted a thorough inspection of the primary circuit, confirming its sound condition.
The outage preparations for refuelling began years in advance as part of a strategic plan.
The power station has been operational since 1995.
