Decommissioning sites in scope of EIADR

Details on each of the sites currently in scope of EIADR or that have started the process of applying for an EIADR consent are below.

Sites that currently have EIADR consent are required to produce an annual EMP (unless otherwise agreed with ONR) which provides details on the progress of the decommissioning project and how the impact on the environment of that work is being managed.

Berkeley

Berkeley Nuclear Power Station started generating electricity in 1962 and ceased generation in 1989. As this was prior to EIADR coming into force, the licensee, British Nuclear Fuel plc, did not require consent from ONR to commence the decommissioning project.

HSE considered a change to the decommissioning project at Berkeley Nuclear Power Station under Regulation 13 of EIADR to construct a purpose built ILW store for the storage of waste from the site and determined that an Environmental Impact Assessment was not required. HSE has published a report, which describes the main reasons on which the decision is based.

Bradwell

Bradwell Nuclear Power Station started generating electricity in 1962 and ceased generation in 2003. HSE granted consent to the licensee of Bradwell Nuclear Power Station, Magnox Electric Ltd (now Magnox Ltd), to carry out a decommissioning project under EIADR on 5 December 2003. HSE has published a report which describes the reasons and considerations for its decision. ONR has agreed that EMPs for the Bradwell site will be submitted on a 5-yearly basis as the site is currently in a quiescent state during the Care and Maintenance (C&M) stage.

Calder Hall

Calder Hall Nuclear Power Station started generating electricity in 1956 and ceased generation in 2003. HSE granted consent to the licensee of Calder Hall Nuclear Power Station, British Nuclear Group Sellafield Ltd (now Sellafield Ltd), to carry out a decommissioning project under EIADR on 21 June 2005. HSE has published a report which describes the reasons and considerations for its decision.

Chapelcross

Chapelcross Nuclear Power Station started generating electricity in 1959 and ceased generation in 2005. HSE granted consent to the licensee of Chapelcross Nuclear Power Station, Magnox Electric Ltd (now Magnox Ltd), to carry out a decommissioning project under EIADR on 26 September 2005. HSE has published a report which describes the reasons and considerations for its decision.

Dounreay

Dounreay Site started operating in 1955 and ceased operations in 1994. As this was prior to EIADR coming into force, the licensee, Dounreay Site Restoration Ltd, did not require consent from HSE to commence the decommissioning project.

HSE considered a change to the decommissioning project at Dounreay site under Regulation 3 of EIADR to construct a purpose built Low Level Radioactive Waste (LLW) repository and determined that an Environmental Impact Assessment was not required.

Dungeness A

Dungeness A Nuclear Power Station started generating electricity in 1965 and ceased generation in 2006. HSE granted consent to the licensee of Dungeness A Nuclear Power Station, Magnox Electric Ltd (now Magnox Ltd), to carry out a decommissioning project under EIADR on 13 July 2006. HSE has published a report which describes the reasons and considerations for its decision.

Harwell

Harwell Atomic Energy Research Establishment, now Harwell Site, started operating in 1946 and ceased operations in 1990. As this was prior to EIADR coming into force, the licensee, the United Kingdom Atomic Energy Authority (UKAEA) (now Magnox Ltd), did not require consent from ONR to commence the decommissioning project.

Hinkley Point A

Hinkley Point A Nuclear Power Station started generating electricity in 1965 and ceased generation in 2003. HSE granted consent to the licensee of Hinkley Point A Nuclear Power Station, Magnox Electric Ltd (now Magnox Ltd), to carry out a decommissioning project under EIADR on 10 July 2003.

Hinkley Point B

Hinkley Point B Nuclear Power Station started generating electricity in 1976 and ceased generation in 2022. The station is now in the process of seeking an EIADR consent for the decommissioning of the site. EDFE submitted a Scoping Report to ONR in October 2022 covering the environmental issues and aspects that will be addressed in the Environmental Impact Assessment and requested a Pre-Application Opinion (PAO) from ONR. ONR responded to EDFE with its PAO for Hinkley Point B in December 2022.

Hunterston A

Hunterston A Nuclear Power Station started generating electricity in 1964 and ceased generation in 1990. As this was prior to EIADR coming into force, the licensee, Magnox Electric plc (now Magnox Ltd), did not require consent from ONR to commence the decommissioning project.

Hunterston B

Hunterston B Nuclear Power Station started generating electricity in 1976 and ceased generation in 2022. We granted consent to the licensee, EDF Energy Nuclear Generation Ltd, to carry out a decommissioning project under EIADR on 9 August 2024. A Project Assessment Report has been published that describes the reasons and considerations for our decision.

Oldbury

Oldbury Nuclear Power Station started generating electricity in 1976 and ceased generation in 2012. HSE granted consent to the licensee of Oldbury Nuclear Power Station, Magnox Electric Ltd (now Magnox Ltd), to carry out a decommissioning project under EIADR on 18 February 2008. HSE has published a report which describes the reasons and considerations for its decision.

Sizewell A

Sizewell A Nuclear Power Station started generating electricity in 1966 and ceased generation in 2006. HSE granted consent to the licensee of Sizewell A Nuclear Power Station, Magnox Electric Ltd (now Magnox Ltd), to carry out a decommissioning project under EIADR on 26 May 2006. HSE has published a report which describes the reasons and considerations for its decision.

Submarine dismantling project

The Submarine Dismantling Project (SDP) is a project to decommission 7 of the UK’s nuclear powered submarines. ONR granted consent to the licensee for the SDP, Rosyth Royal Dockyard Limited, to carry out the decommissioning of the 7 nuclear submarines currently at Rosyth Royal Dockyard in October 2014. ONR has published a report which describes the reasons and considerations for its decision.

Trawsfynydd

Trawsfynydd Nuclear Power Station started generating electricity in 1965 and ceased generation in 1991. As this was prior to EIADR coming into force, the licensee, British Nuclear Fuel plc (now Magnox Ltd), did not require consent from ONR to commence the decommissioning project.

Winfrith

The Winfrith Reactor Research and Development Site, now Winfrith Site, started operating in 1957 and ceased operations in 1995. As this was prior to EIADR coming into force, the licensee, the United Kingdom Atomic Energy Authority (UKAEA) (now Magnox Ltd), did not require consent from ONR to commence the decommissioning project.

Wylfa

Wylfa Nuclear Power Station started generating electricity in 1971 and ceased generation in 2015. ONR granted consent to the licensee of Wylfa Nuclear Power Station, Magnox Ltd, to carry out a decommissioning project under EIADR on 25 September 2013. ONR has published a report which describes the reasons and considerations for its decision.

Wylfa previously obtained consent under EIADR in March 2009, but due to extensions to power generation, decommissioning was due to start after the 5 year period for which this consent applied and hence applied for consent again in 2013.
