On 31 March 2010 the Civil Nuclear Constabulary (CNC) employed 832 police officers and 140 police staff—which includes firearms training instructors plus training and armoury personnel. On 31 March 2011 this was 826 and 156, respectively. Details on the roles, responsibilities and composition of CNC are contained in the Civil Nuclear Police Authority's (CNPA) annual reports and strategic plans which are available on
Security arrangements at all civil nuclear sites are kept under constant review as part of a continuous process to ensure existing arrangements are robust and effective. There is an ongoing uplift in the operational capacity of the CNC which will see an increase in CNC police numbers by 31 March 2012. The CNC uplift is addressing the range of priorities articulated by the Government in order to meet the risks faced by the UK that were contained in the strategic defence and security review, and this is expected to lead to ongoing increases in CNC police officers beyond 2012.
