The formation of AWE
In 1987, AWRE was combined with ROF Burghfield and ROF Cardiff to form the Atomic Weapons Establishment (AWE),
these sites being renamed AWE Burghfield and AWE Cardiff (the latter was closed in 1997).
It remained with the Ministry of Defence, Procurement Executive. However, in 1989, the UK government announced its intention to find a suitable private company to run AWE under a Government Owned/Contractor Operated (GO‑CO) arrangement.

In 1999 Hunting-BRAE lost the contract to AWE Management Ltd (AWE ML), a consortium of
BNFL,
Lockheed Martin and
Serco. AWE ML's subsidiary, AWE plc, assumed responsibility for the operation of all AWE sites on 1 April 2000. This was not full privatisation as the
Ministry of Defence continued to own all the AWE sites as well as a
golden share in AWE plc.
Critics pointed out that BNFL and Lockheed Martin did not have perfect safety records either. BNFL suffered embarrassing revelations of falsified quality checks in nuclear fuels and Lockheed was the subject of scathing reports on the operation of US nuclear facilities. Lockheed's failings included safety concerns at the
Y-12 facility at
Oak Ridge, Tennessee, an American weapons plant similar in certain ways to Aldermaston.
In December 2008, the BNFL share in AWE Management Ltd was sold to

reported that a scientist at AWE, who had worked on Britain's
early atomic bomb programme decades before, recognised a small spike at an energy of 803 kilo-electron volts (keV) as the gamma ray signal from polonium-210, a critical component of early nuclear bombs, which led to the correct diagnosis. Further tests using spectroscopy designed to detect alpha radiation confirmed the result.
In July 2015 the
issued an improvement notice to AWE demanding that it demonstrate that it has a long-term strategy for managing Higher Active radioactive Waste in order to reduce the risk to the public and its employees.
In 2011 a project named MENSA to construct a new warhead assembly and disassembly facility at Burghfield had been approved, to be completed in 2017 at a cost £734 million. In 2020, a
National Audit Office report found that costs had increased by £1.07 billion to £1.8 billion and completion date had slipped to 2023. Construction was begun before design had been finalised and risk was not shared with contractors, so they were not incentivised to control costs.
Return to government management
In November 2020, it was announced that the Ministry of Defence had triggered a contractual break point and would take ownership of AWE Plc in July 2021.
Sir John Manzoni has been announced as chair-designate, and will formally take on the role of chair of the board on 1 July 2021.

AWE's responsibilities
AWE is tasked to help the United Kingdom maintain a credible and effective minimum nuclear deterrent:
* To maintain the warheads for the

The trident is the weapon of Poseidon, or Neptune, the God of the Sea in classical mythology. The trident may occasionally be held by other mari ...

* To maintain a capability to design a new weapon, should it ever be required.
* To complete the dismantling and disposal of redundant warheads replaced by Trident.
* To develop the skills, technologies and techniques that could underpin future arms limitation treaties.
A significant programme of investment took place over the three-year period from 2005 to 2008, of about £350 million per year, to provide assurance that the existing

disposal, was estimated at £3.4 billion in 2005.
Safety record
On 3 August 2010 a fire broke out in the explosives processing area at AWE Aldermaston, resulting in the evacuation of nearby residents from their homes. Investigations by a local newspaper revealed that from 1 April 2000, to 5 August 2011, 158 fires broke out at AWE sites, with the fire brigade being called out to deal with alarms on average four times a week over this period. The Health and Safety Executive took the decision to prosecute AWE plc on three charges relating to health and safety after their investigation into the fire in 2010, the first hearing in this case being held on 6 August 2012. On 16 May 2013 AWE pleaded guilty to a single offence contrary to the Health and Safety at Work Act 1974.

The expertise is to be used as part of Britain's contribution to the
