The '''Nuclear Decommissioning Authority''' ('''NDA''') is a [[non-departmental public body]] of the [[Department for Energy Security and Net Zero]] (formerly the [[Department for Business, Energy and Industrial Strategy]]) formed by the [[Energy Act 2004]]. It evolved from the Coal and Nuclear Liabilities Unit of the [[Department of Trade and Industry (United Kingdom)|Department of Trade and Industry]]. It came into existence during late 2004, and took on its main functions on 1 April 2005. Its purpose is to deliver the [[Nuclear decommissioning|decommissioning]] and clean-up of the [[Nuclear power in the United Kingdom|UK's civil nuclear]] legacy in a safe and cost-effective manner, and where possible to accelerate programmes of work that reduce hazard.

Although the NDA itself employs about 250 staff, its subsidiaries employ about 15,000 staff across the NDA estate.<ref name = 2020report >{{cite web | url = https://www.gov.uk/government/publications/nuclear-decommissioning-authority-annual-report-and-accounts-2019-to-2020/nda-annual-report-and-accounts-2019-to-2020 | title = NDA Annual Report and Accounts 2019 to 2020 | date = 21 July 2020 | publisher = Nuclear Decommissioning Authority | access-date = 8 June 2021}}</ref>
Its annual budget is £3.5{{nbsp}}billion, the vast majority of which is spent through contracts with site licence companies, who also subcontract to other companies which provide special services. The NDA aims to do this by introducing innovation and contractor expertise through a series of competitions similar to the model that has been used in the United States.

In April 2017, the NDA lost a legal case in the [[UK Supreme Court|Supreme Court]] regarding the [[public procurement|procurement]] of a sizeable contract for the decommissioning of twelve different [[Magnox]] nuclear facilities when EnergySolutions EU (now called ATK Energy EU) challenged a decision in connection with ATK's unsuccessful bid.<ref>[https://www.supremecourt.uk/cases/docs/uksc-2016-0006-press-summary.pdf Press Summary: Nuclear Decommissioning Authority (Appellant) v EnergySolutions EU Ltd (now called ATK Energy EU Ltd) (Respondent) &#91;2017&#93; UKSC 34 on appeal from: &#91;2015&#93; EWCA Civ 1262], 11 April 2017</ref> In February 2018 Parliament's [[Public Accounts Committee (United Kingdom)|Public Accounts Committee]] (PAC) concluded that the NDA had "dramatically under-estimated" costs and "completely failed" in the procurement and management of the [[Magnox Ltd]] contract, which was one of the highest value contracts let by the government. An independent inquiry into the deal was set up.<ref name=wnn-20180703>{{cite news |url=http://www.world-nuclear-news.org/C-NDA-to-take-over-management-of-Magnox-sites-0307185.html |title=NDA to take over management of Magnox sites |publisher=World Nuclear News |date=3 July 2018 |access-date=9 July 2018}}</ref><ref name=pac-20180227>{{cite web |url=https://publications.parliament.uk/pa/cm201719/cmselect/cmpubacc/461/46102.htm |title=The Nuclear Decommissioning Authority's Magnox contract |publisher=UK Parliament |work=Public Accounts Committee |date=27 February 2018 |access-date=9 July 2018}}</ref>

==Activities==

===Objectives===
The main objectives of NDA are to:

*eliminate site hazards and develop waste solutions;
*ensure the highest standards in safety, security and environmental management;
*build an effective world class industry;
*gain full approval and support from stakeholders (employees, contractors, government, local communities and general public); and
*make best use of assets and maximise value-for-money.

===Structure===
[[File:Aerial view Sellafield, Cumbria - geograph.org.uk - 50827.jpg|thumb|[[Sellafield]], NDA's largest site]]
Responsibility for operating the sites has been restructured into five site licence companies (SLC). Management of the SLCs was formerly contracted out to different parent body organisations (PBO), some of which were initially owned by private companies.<ref>[http://www.nda.gov.uk/news/slc-names.cfm NDA Confirms Names of New Site Licence Companies], Nuclear Decommissioning Authority (14 February 2007)</ref> More recently, the NDA has transitioned to a "group approach" of SLCs being wholly-owned NDA subsidiaries <ref name= "NDA Strategy 2021">{{cite web |title=Nuclear Decommissioning Authority Strategy effective from March 2021 |url=https://www.gov.uk/government/publications/nuclear-decommissioning-authority-strategy-effective-from-march-2021/nuclear-decommissioning-authority-strategy-effective-from-march-2021#introduction |website=[[gov.uk]] |access-date=24 July 2023}}</ref>

*[[Sellafield Ltd]] was previously [[British Nuclear Fuels Ltd|BNFL]]'s British Nuclear Group subsidiary. It comprises the [[Sellafield]] nuclear chemical facility and [[Calder Hall]]. It also previously managed the [[Capenhurst]] [[uranium]] enrichment plant, which is now owned by [[Urenco Group|Urenco]].<ref>{{cite news|url=http://www.world-nuclear-news.org/C-Urenco_takes_on_Capenhurst_site-3011125.html |title=Urenco takes on Capenhurst site |publisher=World Nuclear News |date=30 November 2012 |access-date=2012-12-13}}</ref> Its PBO was formerly Nuclear Management Partners Ltd, a consortium of [[URS Corporation|URS]], [[Amec Foster Wheeler]] and [[Areva]]. However, Sellafield Ltd has been under the direct control of the NDA since April 2016.

In 2005, the cost of decommissioning these sites was planned at £55.8{{nbsp}}billion, with Sellafield requiring £31.5{{nbsp}}billion.<ref name=nda-strategy-2005>{{cite report |url=http://www.nda.gov.uk/documents/upload/Draft_Strategy_for_Consultation_2005.pdf |title=NDA Strategy - draft for consultation |page=66 |publisher=Nuclear Decommissioning Authority |year=2005 |access-date=7 December 2013 |url-status=dead |archive-url=https://web.archive.org/web/20091122155158/http://www.nda.gov.uk/documents/upload/Draft_Strategy_for_Consultation_2005.pdf |archive-date=22 November 2009 }}</ref> However, in 2006, the NDA reported that the cost of cleaning up existing waste was higher than previously thought, and gave a new estimated decommissioning cost of about £72{{nbsp}}billion over a 100-year period.<ref name=bbc-20060330>{{cite news|url=http://news.bbc.co.uk/1/hi/business/4859980.stm |title=Nuclear clean-up 'to cost £70bn' |publisher=BBC News |date=30 March 2006 |access-date=2010-05-22}}</ref> In 2008, estimated decommissioning costs increased to £73.6{{nbsp}}billion, or after taking account of [[discount window|discount rates]], £44.1{{nbsp}}billion.<ref>{{cite web|url=http://www.nda.gov.uk/news/arac-0708.cfm |title=Annual Report & Accounts 2007/08 |publisher=Nuclear Decommissioning Authority |access-date=2010-05-22}}</ref> A 2006 estimate foresaw £14{{nbsp}}billion of offsetting income from reprocessing fuel at [[Sellafield]].<ref name=bbc-20060330 /> In 2009, the NDA sold land near three existing reactor sites for expected new nuclear power stations, for over £200{{nbsp}}million.<ref>{{cite news|url=http://www.timesonline.co.uk/tol/news/environment/article5992467.ece |title=Prices soar as bidders fight for nuclear sites |publisher=The Sunday Times |date=29 March 2009 |author=Danny Fortson and Dominic O’Connell |access-date=2010-05-22}}{{dead link|date=September 2024|bot=medic}}{{cbignore|bot=medic}}</ref>

In 2013, a critical [[Public Accounts Committee (United Kingdom)|Public Accounts Committee]] report stated that the private consortium managing Sellafield has failed to reduce costs and delays. Between 2005 and 2013, the annual costs of operating Sellafield increased from £900{{nbsp}}million to about £1.6{{nbsp}}billion.

==National Nuclear Laboratory==
In 2006, the then Secretary of State for Trade and Industry announced his support for a [[National Nuclear Laboratory]] (NNL) to be based on the British Technology Centre at Sellafield and Nexia Solutions.<ref>[http://www.nda.gov.uk/stakeholders/newsletter/nnl-announced-sos.cfm Alistair Darling announces the formation of the National Nuclear Laboratory] {{Webarchive|url=https://web.archive.org/web/20081213162250/http://www.nda.gov.uk/stakeholders/newsletter/nnl-announced-sos.cfm |date=2008-12-13 }}, Nuclear Decommissioning Authority (30/06/06).</ref> The NDA, as the owner of Sellafield site and the funder of majority of research required across the nuclear estate, was involved establishing the NNL in 2009. The NNL complements other initiatives to develop a sustainable workforce such as the National Skills Academy for Nuclear (NSAN) network, including the development of Energus in West Cumbria, alongside complementary research and development facilities such as the Dalton Nuclear Institute.
