It is home to a uranium enrichment plant owned by Urenco Group.
[edit] Capenhurst tower
In 1999 Channel 4 and Duncan Campbell revealed that a fifty metre high tower on the premises of the uranium enrichment plant had been used to intercept telephone calls transmitted by microwave between the British Telecom towers at Gwaenysgor, Clwyd, and Pale Heights, near Chester. The tower was built during 1989 and 1990 to intercept phone calls between the Republic of Ireland and the United Kingdom. (A temporary listening post was placed on the roof of the plant during 1988.) The main route for phone calls between Ireland and the UK was via the submarine fibre optic cable UK-Ireland 1 which reached the UK at Holyhead, Anglesey. From there the signals were transmitted by microwave.
Phone calls were monitored by GCHQ until 1998 when the Irish telecomunication system was changed.
The tower was demolished in 2004 because the government could not find a buyer.
