Unloading the spent fuel
Fuel assemblies are removed from the reactor core prior to storage during a unit outage at the Golfech plant. The assemblies will be stored for at least a year in an adjacent pool. Loading and unloading operations are carried out underwater. The water absorbs the heat released by the fuel and provides effective radiation shielding. The characteristic blue colour of the water is due to the Cherenkov lighting effect, which occurs as electrons are emitted by beta disintegration.
