The Littlebrook ‘A’ and ‘B’ stations had been used by Nuclear Electric, later to become BNFL as a training and development centre.
Magnox reactors were designed to be maintenance-free during their operational lifetime, however development of new techniques for working on them needed to take place before attempting new procedures on live reactors. This is where FRED came in – the Facility for Reactor Engineering and Development, where reactor inspection and repair rehearsal rigs were constructed. This is a mock-up of the reactors at Bradwell nuclear power station, used during the development of robotic equipment.
A range of mock-up nuclear reactors had been built, the ‘A’ station containing mock-ups of the reactors at Sizewell, Bradwell and Dungeness ‘A’ power stations.
