Windscale Advanced Gas Cooled Reactor (WAGR)

The Windscale Advanced Gas Cooled Reactor (WAGR) (http://www.ukaea.org.uk/wagr/history.htm) was a prototype for the UK's second generation of reactors, the Advanced gas-cooled reactor or AGR, which followed on from the Magnox stations. The WAGR golfball is, along with the Pile chimneys, one of the iconic buildings on the Sellafield site. This reactor was shut down in 1981, and is now part of a pilot project to demonstrate techniques for safely decommissioning a nuclear reactor.
