A fire at the Atomic Weapons Establishment (AWE) in Aldermaston had not been a cause for public concern, officials said this week.
Members of AWE's Local Liaison Committee (LCC) were given the chance to inspect the damaged building on Thursday last week.
The fire broke out at in a building containing non-nuclear explosives on Tuesday August 3.
Roads around the AWE site were locked down for 11 hours and 14 residents had to be evacuated from their homes on Red Lane.
One AWE employee was injured in the fire and received first aid.
The cause of the blaze is under investigation by the Hazardous Installations Directorate of the Health and Safety Executive and AWE itself.
The results of the investigation will be made public.
AWE's local Liaison committee, which represents 14 local authorities in Hampshire and Berkshire, is made up of 30 local and parish councillors and headed by AWE chief executive officer Robin McGill.
He said: “We wanted to show local councillors that the building is intact and has suffered minor damage in what was a relatively small fire.
“There have been some inaccurate reports about the scale of the incident and it is important that LLC members are in a position to reassure local people.”
Aldermaston parish councillor David Shirt said: “We were taken to see the damaged building.
“The building was a brick structure and there was a big perspex front on the building which had melted.
“The roof also had some damage to it and there was some asbestos insulation hanging down.
“My immediate reaction was that it was a very small fire and we were assured by AWE that they had done tests around the site and there was no contamination.”
Cllr Shirt, who had never been on the AWE site before, said that all related operations had been stopped and AWE appeared to be 'ultra cautious'.
The blaze is believed to have been a solvent fire away from any explosives.
Cllr Shirt added: “They told us the there was no danger of a fire causing an explosion, so that was quite reassuring.
“The key question still is how the fire was started, which we hope to find out in the report that we are told is due in a matter of weeks rather than months.”
