Sizewell B power station came back online today, generating enough low carbon electricity to serve two million homes.

EDF Energy took the decision to bring the Suffolk power station offline in March following the failure of some heaters in a component known as the pressuriser.

Using bespoke designed equipment, video footage was taken of the pressuriser which enabled engineers to examine it in the smallest detail.

A repair strategy was then tested on a 16metre x 2 � metre replica of the equipment before being successfully completed on the pressuriser.

Jim Crawford, Sizewell B Station Director said: “Working within the EDF family of companies we have been able to draw on international expertise throughout this project.

“This has given us access to industry experts who, working closely with our local team, have been instrumental in bringing Sizewell B back to service.”

The work carried out on repairs has been regularly monitored by the industry regulator the Nuclear Installations Inspectorate (NII), part of the Health and Safety Executive (HSE).
