Attlee set up a cabinet sub-committee, the Gen 75 Committee (known informally as the "Atomic Bomb Committee"), on 10 August 1945 to examine the feasibility of a nuclear weapons program. In October 1945, it accepted a recommendation that responsibility be placed within the Ministry of Supply. The Tube Alloys Directorate was transferred from the Department of Scientific and Industrial Research to the Ministry of Supply on 1 November 1945. To coordinate the effort, Lord Portal, the wartime Chief of the Air Staff, was appointed Controller of Production, Atomic Energy (CPAE), with direct access to the Prime Minister. An Atomic Energy Research Establishment (AERE) was established at RAF Harwell, south of Oxford, under the directorship of Cockcroft. AERE moved to Aldermaston in 1952. Christopher Hinton agreed to oversee the design, construction and operation of the new atomic weapons facilities. These included a new uranium metal plant at Springfields in Lancashire, and nuclear reactors and plutonium processing facilities at Windscale in Cumbria. Hinton established his headquarters in a former Royal Ordnance Factory at Risley in Lancashire on 4 February 1946.
