Aldermaston


AWE Aldermaston is the central facility of the British nuclear weapon establishment.

It is officially located at Aldermaston, near Reading, in Berkshire, although the main entrances are in the nearby village of Tadley.

This facility not only performs most research activities, it also develops weapon designs, and manufactures the majority of weapon components, including nuclear components. It was officially established 1 April 1950 on the site of a World War II airfield. Weapons development work was transferred there from the codenamed “High Explosive Research” (HER) project at Fort Halstead in Kent. The AWE employs about 5000 people.

The facility at Aldermaston covers 880 acres and is broken up into 11 areas. The main administration building is F6.1 in the F area. Area A is known as the Citadel, it occupies the north side of the site and includes the plutonium manufacture and pit fabrication facilities. The A1 plutonium manufacturing buildings were the original fabrication facilities that opened in the early to late 50s. They became badly contaminated in 1978 and were closed, but were reopened in 1982 to manufacture the Chevaline warheads. Operation continued long after its planned closing date, and it manufactured the first Trident warheads. The replacement A90 complex began construction in 1983 and after many delays went into operation in 1991 (5 years late). The A90 complex has 300 glove-box production units, and now handles Trident plutonium component production.

AWE Aldermaston is organized into three major departments relating to weapons development: the Warhead Physics Department, the Warhead Design Department, and the Materials Department.

The Warhead Physics Department is responsible for research and analysis of the fundamental physical processes involved in nuclear weapons. It is divided into the Mathematical Physics Division (conducts theoretical work and computer modelling and simulation), the Warhead Hydrodynamics Division (conducts experimental work in the processes of weapon assembly and disassembly), the Radiation Physics Division (conducts experimental work in both nuclear radiation physics and radiation hydrodynamics).

The Warhead Design Department develops the complete nuclear weapon design. It is divided into the Weapon Engineering Division (“physics package” design), the Weapon Diagnostics Division (system testing for EMP and nuclear hardening, etc.), and the Electronic Systems Division (fuzing and arming systems development).

The Materials Department develops the materials and processes required to design and manufacture nuclear weapons. It is divided into the Chemistry and Explosives Division, the Chemical Technology Division, and the Metallurgy Division.

“Spending £100 billion on replacing Trident is a catastrophic folly. I’m sure I am one of many who support the those, like Action-AWE, who campaign actively and imaginatively against it”

– Ken Loach

John Hurt

".....the government has pledged to rebuild a new generation of British nuclear weapons at enormous cost and at a time when social services budgets including those for health and education are being drastically cut. Having nuclear weapons doesn't make us safer, it just brings the possibility of nuclear conflict ever closer. We need to protect this planet not put it at even more risk of destruction. We all have a voice so please use yours and join me in supporting ACTION AWE." John Hurt
