Nuclear Accident Response Team


The Ministry of Defence maintains a Nuclear Accident Response Organisation (NARO) to deal with the consequences of any accident (including one arising through terrorist acts) affecting the UK, or Overseas Territories, involving nuclear weapons, special nuclear materials, nuclear facilities or naval reactors. (See section below on the NARO).

Planning for nuclear accident response is undertaken in varying detail depending on the assessed probability of an accident occurring and of it resulting in a public health hazard.  In addition to having a proper concern for public safety, the MOD as a Department of State has to consider the sensitive and sometimes unique nature of its operations, the consequences of a defence nuclear accident for national defence policy and the public expectations of a Government Department.  Emergency preparedness for accidents which may affect members of the public involves many external organisations, such as local authorities, other Government Departments and emergency services, some of whom have specific statutory responsibilities. Accordingly, it is essential that planning for nuclear accident response is conducted in an open manner and in conjunction with the appropriate authorities both to meet the Department’s legal obligations, to provide information and for external authorities to gain confidence in the efficacy of the arrangements.

The MOD conducts a regular series of exercises, involving local authorities, local emergency service and agencies across government in order to ensure the effectiveness of the nuclear accident emergency plans.
