Introduction
The second building to be completed was named Lab 2 and it was to house a large centrifuge. Built by Napier Engineering, and construction of the building commenced in 1955.
In order to meet this demanding specification, the consulting engineers designed a unique and substantial building. Reinforced concrete walls rose from the concrete raft, incorporating a number of equipment and service rooms together with an overhead crane system. The concrete raft incorporated a large 9 metre diameter circular chamber to accommodate the large centrifuge. Shingle was then banked up all around the building to roof level. The design of the roof was similar to that of Lab 1 and in the event of a failure the explosive force would project the roof upwards.
Following the priority completion of Lab 1 in April 1956, the workforce were then focussed on the completion of Lab 2 later that year.
The centrifuge was thought to be the largest in the UK at the time and was capable of supporting a 450 kg test piece at 100g.
The centrifuge was removed from Orford Ness when the site closed in 1971. Following modernisation work, the centrifuge is still believed to be in service today at AWE Aldermaston.
