Devonport Royal Dockyard

This section provides access to Devonport Royal Dockyard site-specific regulatory and related information including Environmental Monitoring Results and Local Liaison Committee arrangements (see links at the bottom of this page).

Radiation (Emergency Preparedness and Public Information Regulations 2001 (REPPIR) establishes a framework from which to protect the public from radiation accidents. The presence of nuclear-powered submarines at Devonport means there is a small risk of a radiation emergency.

REPPIR requires the Ministry of Defence and Babcock as the on-site operators for Devonport Royal Dockyard, to have an emergency plan in place to deal with any reasonably foreseeable radiation emergency.

Further Information

To facilitate comparison of the various surveys carried out in the Plymouth area, results from the Environment Agency (EA)/Food Standards Agency (FSA)/ Centre for Environment, Fisheries and Aquaculture Science (Cefas) and Babcock surveys can be seen by following the links below. These are the latest published reports. Some differences between the results are to be expected because of the statistical uncertainties inherent in the measurement of radioactivity at the low levels present in the environment.

Available Reports:


Babcock makes regular surveys of radioactivity in the marine environment in accordance with the requirements of its Permit for the discharge of radioactive waste, issued by the Environment Agency.

Monitoring for radioactivity is carried out at various locations along the banks of the Rivers Tamar, Lyner, Tavy and Plym. Measurements are made of environmental gamma dose rates and samples are taken of the sediment along the low waterline, and of seaweed, mussels and river water at various points. The monitoring points and arrangements for monitoring, sampling and analysis have been agreed with the Environment Agency.

The link below takes you to the Radioactivity in Food and the Environment annual report, RIFE-23. This report combines the results of independent monitoring for radioactivity in the environment carried out by the Environment Agency and Centre for Environment, Fisheries and Aquaculture Science (CEFAS) on behalf of the Food Standards Agency.

The Local Liaison Committee was formed to provide a forum for members to gather information about general operations undertaken on the Babcock and Naval Base site at Devonport and discuss health, safety and environmental issues which may impact on public safety. The Committee meets twice yearly, chaired alternately by the Ministry of Defence and Babcock.

The next Local Liaison Committee meeting will be held at Welcome Hall, Fore Street, Devonport. The time and date will be confirmed shortly.

The meeting will give Committee members the opportunity to hear about current Dockyard activities from senior Babcock staff and from MoD officials. Members of the public are welcome to attend and individuals can, in advance of the meeting, ask their representatives on the Committee to put particular questions to the Babcock and MoD personnel.

Minutes of the meeting held on 18 July 2019 will be available here shortly. If you would like to receive a copy of the enclosures to these minutes, please call 01752 324745.
