The original deaerator corridor on +10m outside the Unit 4 control room is rarely seen by visitors to the control room, but we had to use it because of work on the Perimeter Closure Project. The reserve control room to Unit 4 is behind the wall on the right, shielded with heavy lead plate. It looked directly out on the vast heap of radioactive debris from the reactor building. Some original linoleum flooring is also visible.
