All persons and organisations within the Detailed Emergency Planning Zone (DEPZ) have been issued with information on what to do in the event of an Off-Site Nuclear Emergency. (Refer to Sellafield Site: Warning and Informing Information and Telephone Warning System).


Outline Planning Zone

The Outline Planning Zone is a new factor under the Radiation (Emergency Preparedness and Public Information) Regulations 2019 and additional elements have been considered in order to improve emergency arrangements.  This does not mean that there is now extra risk to the public.

Note: Lancashire County Council has responsibility under the Radiation (Emergency Preparedness and Public Information) Regulations 2019 for Heysham Power Station.  The Outline Planning Zone for this nuclear site is 30km, this means that part of the zone will sit within the Southern part of Cumbria.

The call from the council follows work undertaken by the Office for Nuclear Regulation in January 2014 when they reviewed their process for revising the Detailed Emergency Planning Zones around UK civil nuclear establishments. This revision came from lessons learnt from the Fukushima Daiichi Nuclear Power Plant incident in 2011 and has had a considerable impact in how Cumbria County Council, Sellafield Ltd and the emergency services plan for an incident on the west coast.

The size of the emergency planning area differs site by site in the UK, with consideration given to individual factors associated with each site. The Detailed Emergency Planning Zone for Sellafield covers an area ranging from approximately 6.1km - 8km from the centre of the site.

If you do not have access to the internet you may wish to ask a friend or neighbour to assist or you in signing up for the service.
