The nuclear reactor at Sizewell power station in Suffolk has ben shut down.
The plant produces enough electricity to supply two million homes. It's being taken off-line for 6 weeks while engineers carry out work to remove spent fuel rods and replace them with new ones. Serena Sandhu reports.
The proposed new Sizewell C nuclear power station could create more than 5,500 jobs in the construction sector.
Plans are being released today by EDF Energy for building the new French designed European Pressurised Reactor, or EPR, on the Suffolk coast.
The EPR uses two nuclear reactors within the same single plant to produce 3.2 gigawatts of power.
