Decommissioning of retired civil nuclear sites was an afterthought
when the UK’s pioneering nuclear industry was established. Decades
of poor records of the state and location of hazardous materials
and “weak” Government oversight has left the Nuclear
Decommissioning Authority (NDA) with the legacy of a “perpetual”
lack of knowledge about the condition of the UK’s nuclear sites it
is responsible for making safe.
This ongoing lack of knowledge was a significant factor in the
failure of the Magnox procurement and original contract, which
seriously damaged the NDA’s reputation and has now cost the
taxpayer in excess of £140 million, and it continues to be a
major barrier to making progress.
The NDA acknowledges that it still does not have full
understanding of the condition of the 17 sites across its estate,
including the 10 former Magnox power stations. According to its
most recent estimates it will cost current and future generations
of UK taxpayers £132 billion to decommission the UK’s civil
nuclear sites, and the work will not be completed for another 120
years - with significant impacts on the lives of those who live
near the sites.
The NDA’s estimate of the cost just to get the sites to the ‘care
and maintenance’ stage of the decommissioning process has
increased by between £1.3 billion and £3.1 billion in just three
years since 2017, to between £6.9 billion and £8.7 billion. The
PAC says past experience with the NDA suggests even these
estimates will soon be out of date and costs may increase
further.
The Committee says the NDA is not doing enough to exploit the
valuable technical skills and new technologies in the UK nuclear
industry, either for the benefit of local communities or the UK
economy as a whole. The UK was the first country to establish a
civil nuclear power generation industry and is still a world
leader in nuclear decommissioning technology. The NDA also holds
substantial assets in terms of land and employment opportunities
that could be used to serve local communities.
, Chair of the Public Accounts Committee,
said: “The UK went from leading the world in
establishing nuclear power to this sorry saga of a perpetual lack
of knowledge about the current state of the UK’s nuclear sites.
With a project of this length and cost we need to see clearer
discipline in project management.”
,
deputy Chair of the Public Accounts Committee, said:
“Although progress has been made since our last report,
incredibly, the NDA still doesn’t know even where we’re currently
at, in terms of state and safety of the UK’s disused nuclear
sites. Without that, and after the serious knock to the NDA’s
reputation in the Magnox contracting disaster, it is hard to have
confidence in future plans or estimates.
“The UK nuclear industry has valuable technical skills and is
still a world leader in nuclear decommissioning technology. The
NDA, with stronger, better oversight from Government, must make a
clear break with the incompetence and failures of the past and
step up to maximise these assets, and the astronomical sums of
taxpayers’ money it has absorbed, for the benefit of local
communities and the post-Covid recovery of the UK economy as a
whole.
“Generations of taxpayers and local residents will continue to be
impacted just by cleaning up these sites - the process must be
made to work for them. The NDA have a duty to those taxpayers to
ensure that they provide value for money for everything they do.
“In tandem with this, the NDA should be helping to export these
capabilities the world over - it should be a force for and part
of our economic recovery over the coming decade, instead of the
damaging drain on resources, more precious than ever now, it has
been allowed to become.”
PAC report conclusions and recommendations
-
There remains significant uncertainty over the cost and
timetable for decommissioning the Magnox sites and estimates
continue to increase. The NDA acknowledges that it
does not have full understanding of the condition of the 17
sites across its estate, including the 10 former Magnox power
stations. Consequently, there is significant uncertainty about
how long decommissioning will take and how much it will cost.
The NDA considers that it now has its best estimates yet of the
cost and timetable for taking the Magnox sites to the ‘care and
maintenance’ stage of the decommissioning process, but the
latest estimates cover a very broad range of outcomes. The NDA
now estimates that it will cost between £6.9 billion and £8.7
billion, between £1.3 billion and £3.1 billion more than its
previous estimate made in 2017, and will take between 12 and 15
years for the Magnox sites to reach the care and maintenance
stage of the decommissioning process. Our past experience
suggests these estimates will soon be out of date and that
costs may increase further. Reliable estimates of the potential
costs and duration of decommissioning each site are important
to support decision-making about the most efficient ways to
decommission the sites and the order in which they should be
tackled. We are concerned that the NDA’s ambition to
decommission more quickly and efficiently will be hindered by
this perpetual lack of knowledge about the condition of sites.
Recommendations:
The Nuclear Decommissioning Authority should set out how it will
develop a clearer means of reporting publicly on the level of
uncertainty and risk across its sites.
The Nuclear Decommissioning Authority should also set out how it
will prioritise its work on its sites in order to decommission
them in the safest and most efficient way.
-
The uncertainty affecting the Magnox sites reflects a
wider uncertainty about the costs and timetable of
decommissioning the whole civil nuclear estate.
According to the NDA’s most recent estimates it will cost the
UK taxpayer £132 billion to decommission the UK’s civil nuclear
sites and the NDA estimates that the work will not be completed
for another 120 years. The largest proportion of this cost is
to clean up and decommission the NDA’s largest site at
Sellafield, but the cost to decommission the NDA’s Magnox sites
is also substantial, as is the liability associated with
decommissioning the next family of nuclear power stations,
known as the Advanced Gas-Cooled Reactors (AGRs). The money
held in the Nuclear Liabilities Fund, which exists to fund the
decommissioning of the AGRs specifically, was increased from
£9.5 billion by an additional £5.07 billion this year to
reflect the latest estimate of the work required. The NDA is
consulting publicly about its strategy for cleaning up its
nuclear sites. It may be possible to reduce the time it will
take to fully decommission the sites of former nuclear power
stations from around 85 years to more like 40-45 years. This
could significantly reduce the long-term cost of
decommissioning the sites as 40% of the overall decommissioning
cost can be spent in maintaining, operating and safeguarding
the sites while decommissioning activity is taking place. There
is also an opportunity to save taxpayers’ money by accelerating
the programme to create a deep storage facility, known as the
Geological Disposal Facility, to store highly radioactive waste
that is currently held at interim facilities at Sellafield and
the sites of former power stations elsewhere in the UK. The NDA
and the Department are consulting the relevant regulators and
interested communities to identify a suitable site for such a
facility, but were not able to indicate a timeframe in which it
might be achieved.
Recommendations:
Taking into account the feedback from its public consultation,
the Nuclear Decommissioning Authority should exploit
opportunities to reduce the time taken to decommission its sites,
and should identify the impact of such reductions on the cost
profile.
The Department and the Nuclear Decommissioning Authority should
take whatever steps are necessary to provide a firmer estimate of
the cost of decommissioning the sites of the Advanced Gas-Cooled
Reactors so that the public has a more reliable indicator of the
scale of the public liability.
The Nuclear Decommissioning Authority and the Department should
make it a priority to progress their plans to find a location for
a Geological Disposal Facility in order to reduce interim storage
costs at Sellafield and elsewhere, and should confirm when they
consider such a Facility might feasibly become available for the
storage of waste.

A shortage of the right skills within the Nuclear
Decommissioning Authority and across the nuclear industry
remains a significant barrier to progress. In our 2018
report on the failure of the Magnox contract we were highly
critical of the lack of skills – particularly commercial skills
– in the NDA. There is also a shortage of technical skills in
the pipeline. Since then, the NDA has increased its focus on
recruiting experienced staff to its own executive team and to
the leadership of its subsidiaries which manage the sites on a
day to day basis. But recruiting the right skills remains a
significant challenge, particularly with the NDA and its
subsidiaries competing with the private sector for the same
people. It is encouraging that the NDA and the Department are
attempting to meet the skills challenge with, for example, the
introduction of the nuclear graduate scheme to increase
capacity in the sector as a whole. It is also encouraging to
hear that 46% of the latest cohort to the scheme were women.
The Department says that it has made its own improvements in
capacity and capability to oversee the NDA’s activities but, as
we often see, salaries in the civil service mean that the
Department risks losing skilled staff to private sector
organisations in the industry.
Recommendation: Within 6 months of publication of this
report, the Department and the Nuclear Decommissioning Authority
should publish a detailed plan for how they plan to meet the
demand for skills across the UK nuclear industry over the next
5-10 years.
-
For the new delivery model to work, it will be vital
that the Department exercises strong oversight of the Nuclear
Decommissioning Authority and implements the findings of
forthcoming reviews into the failure of the original Magnox
contract and the role of the Authority. Under the
previous delivery model of outsourcing the decommissioning of
nuclear sites to a ‘parent body organisation’ from the private
sector, the Department was a further step removed from
exercising oversight of the decommissioning process than it is
now. Indeed, the Department acknowledges that this led to it
missing some of the problems that arose with the Magnox sites
and contract. The Department tells us that its relationship
with the NDA has changed, with improved oversight of both the
NDA’s strategy and progress with its major projects, a
dedicated team in the Department looking at the NDA, and a
representative of UK Government Investments on the NDA’s own
board who reports to the Department’s accounting officer. But
we remain concerned about the Department’s capacity to oversee
the NDA effectively, and about the number of players from
different parts of Government who are involved. Key to learning
lessons from the past and establishing appropriate oversight
and governance will be implementing the recommendations of the
Holliday inquiry into the Magnox contract and the Department’s
‘Tailored Review’ of the role of the NDA. We welcome the
Department’s commitment to completing and publishing these
reports as a priority, but it is frustrating and concerning
that it is taking so long for these important reviews to be
published.
Recommendations:
On publication of the Holliday report and tailored review, the
Department and the Nuclear Decommissioning Authority should set
out publicly what has been learnt from them and how the reports
are being used to inform the development of the new delivery and
governance models.
In responding to this report, the Department should set out
clearly its rationale for relying on UK Government Investments to
represent it on the Board of the Nuclear Decommissioning
Authority, rather than such oversight being provided directly by
its own team which is dedicated to looking at the NDA.

The Nuclear Decommissioning Authority is not doing
enough to exploit its various assets, either for the benefit of
local communities or the UK economy as a whole. The UK
was the first country to establish a civil nuclear power
generation industry and is still a world leader in nuclear
decommissioning. It can point to some notable achievements in
relation to the decommissioning of the Magnox sites alone, such
as the successful defueling of all the Magnox reactors which
has reduced the level of radioactivity on the sites by 95%, and
the largest clean-up of asbestos waste to have been undertaken
in Europe at Chapelcross. Furthermore, the NDA has provided
advice and exported skills to other countries, including Japan
in relation to the clean-up of Fukushima and the Ukraine in
relation to Chernobyl. The NDA receives around £800 million a
year in income from its commercial activities. Given the
expertise and technologies which the NDA and the UK nuclear
industry have developed over the years, there are further
opportunities, in fields such as Artificial Intelligence and
robotics, with export potential which could benefit the UK
economy and provide jobs for people in local communities. The
NDA also owns and occupies substantial amounts of land. It is
encouraging to hear that around 50 acres of land at Harwell has
been released and is currently home to a manufacturing centre
for coronavirus vaccine. The NDA’s wider estate contains land
which could be exploited for commercial and socially beneficial
use and could provide much needed employment in nearby
communities.
Recommendation: The NDA should develop a strategy for
maximising the economic benefits of developing and, where
appropriate, exporting its knowledge and assets to alleviate the
burden on the taxpayer. These include the skills and experience
of the UK nuclear industry, the decommissioning technologies it
has developed, and the land and other physical assets the NDA
holds.
-
Public accountability is hindered by a lack of
transparency about the scale and nature of the challenge of
decommissioning and the performance of the NDA.
Nuclear decommissioning will cost current and future
generations of taxpayers’ substantial sums of money and has a
significant impact on the lives of those who live near one of
the NDA’s sites. However, little information about, for
example, the timescales for completing decommissioning work and
returning land to communities is readily available to the
public. Greater transparency about progress with
decommissioning would improve public accountability, help to
stimulate improved performance, and increase the visibility to
local communities of the activities and opportunities available
on NDA sites.
Recommendation: NDA should be more transparent about its
current and future plans with the local communities surrounding
its 17 sites to strengthen public accountability and make clear
the socioeconomic impact of its planned activities./ENDS
