The protesters are from the anti-Trident group Trident Ploughshares and the group Block the Builders which opposes the development at Aldermaston. They have chained themselves together and blocking the boilerhouse gate at Aldermaston. The Atomic Weapons Establishment is currently undergoing massive renewal including new computing and laser facilities which will enable to scientists to simulate nuclear explosions to improve the design of nuclear warheads without actually exploding a weapon which would be banned under the Comprehensive Test Ban Treaty. The site was given a £5 billion refit after the signing of the Mutual Defence Agreement with the USA in 2005 which allows the sharing of nuclear information between the USA and Britain.
