London, England (CNN) -- Fire crews have extinguished a fire at a nuclear weapons base west of London, the British Ministry of Defence said Wednesday.
The fire broke out late Tuesday in "a building within the conventional non-nuclear explosives area" of Atomic Weapons Establishment in Aldermaston, Berkshire, about 45 miles west of the British capital, the Ministry of Defence said.
The base fire and rescue service, along with Royal Berkshire firefighters, put out the fire, according to ministry.
One AWE staff member sustained minor injuries.
The ministry said a full investigation has been ordered and there were "no radiological implications" associated with the fire.
