Sizewell is a great power station to work at. The plant itself is huge, and its not easy to get around the RCA as its just so big. The people are friendly, and they have a nice RP set up.
I stayed at Aldeburgh, and worked pre outage and the outage. It's not my favourite place to stay, as its a very expensive place as its a rich persons holiday town.
Most of the refuel techs are from the USA, and were a great bunch to work with.
I am currently working in Australia.
