What the inquiry looked at

“The Ministry of Defence currently has a number of large and complex construction projects for facilities at nuclear-regulated sites. In January 2020 the NAO published a report examining the building or replacing of three nuclear-regulated sites – with a current value of £2.5bn. The report finds that the three projects experienced problems in their earlier and riskier stages, with a cumulative £1.35bn cost increase and delays of between 1.7 and 6.3 years. The report also expresses disappointment that the challenges affecting these projects are not unique, and have been experienced by the Ministry of Defence for decades. The Committee will ask officials from the Ministry of Defence what lessons it has learnt as it completes these projects, and how the Government will be revising the projects’ commercial, regulatory and governance arrangements to ensure value for money for the taxpayer.”

What it found

In the committee's words, from the summary of 2nd Report: Defence Nuclear Infrastructure ↗

The Ministry of Defence (the Department) maintains a submarine-based nuclear deterrent, which relies on a network of programmes, equipment and people, including specialised infrastructure. Poor management of three on-going critical infrastructure projects on nuclear-regulated sites has contributed to a combined cost increase of £1.35 billion and delays of between 1.7 and 6.3 years. Each project suffered significant problems in its early stages and the Department said it immensely regretted the amount of taxpayers’ money lost. It accepts that poor contracting had made it difficult to incentivise better performance from contractors, and that it had not engaged effectively with the nuclear regulatory bodies. It also describes its arrangements for the Nuclear Enterprise in the past as ‘fragmented and balkanised’, with insufficient recognition of the interdependencies between projects.

Since 2016, the Department has negotiated some changes to the contract at one of the three programmes—MENSA—to reduce its financial risk exposure. It has also made some improvements to the oversight of the nuclear enterprise, including the infrastructure projects, through creation of the Defence Nuclear Organisation and the Submarine Delivery Agency. As a result, the Department considers it now has a better understanding and control of the programmes. It has also worked to develop better relationships with the regulators to ensure there is a more effective discussion about the balance between risk and value for money, although it is too early to assess whether all these reforms have been effective. The Department acknowledges that it still has shortages of the specialist skills it needs.

What the government said

The government responded on 21 October 2020. The deadline was 13 July 2020.

Summary written by Accountability Index from the government's response.

The Government states that it "agrees with the Committee's recommendation" on each of the six recommendations, and sets target implementation dates between November 2020 and June 2021.

  • On approvals and risk, it says the recommendation is implemented, citing Project MAID, which has replaced the Initial Gate and Main Gate system with the 3-stage model laid out in the Treasury's Green Book.
  • It will update the Committee on use of the Single Source Contract Regulations, and on corporate memory and skills, "within the December 2020 report to Parliament on the Dreadnought programme".
  • On ring-fencing the nuclear budget, it says discussions with HM Treasury are underway to review the funding model, with "details" to be shared "once discussions have concluded".
  • On ownership of nuclear regulated sites, it says work on the detailed assessment is underway and that "the report will be issued by 31 December 2020".

Concluded (the committee's words)
The Department’s nuclear infrastructure projects have suffered from major cost increases and delays. While we acknowledge the unique complexity and scale of these projects has contributed to costs escalation and this is common to other comparable programmes in other countries, UK cost overruns were caused in large part by avoidable mistakes, such as beginning construction work without mature designs. The three projects will not be delivered to the original plans, will be delayed by between 1.7 and 6.3 years, and will cost a total of £1.35 billion more than originally planned. In particular, MENSA had seen a cost increase of £1.07 billion. Some of these cost increases were the result of poor planning decisions and were avoidable. For example, 48% of the total increased costs and nearly £400 million for MENSA was a result of construction starting before requirements or designs were sufficiently clear, which was time-consuming and costly to subsequently rectify. The Department states that it immensely regrets the amount of taxpayers’ money lost as a consequence, but acknowledges that costs could continue to increase. It notes that similar projects in other countries had also gone over budget, because of the unique complexity, scale and safety standard requirements of nuclear projects. It states that the big lesson from these experiences was the crucial necessity for proper planning before starting to build.

Concluded (the committee's words)
We understand the need to make early progress given the interdependencies between the infrastructure programmes and the requirements of the Dreadnought programme, but the Department did not properly anticipate and manage the risks of starting early. The Department told us it has learned from these experiences and has paused another Atomic Weapons Establishment project—Project Pegasus for the construction of a manufacturing facility for enriched uranium—in order to ensure that the design is mature enough and that requirements for the future warhead are clear. Recommendation: In the future, the Department must more explicitly identify and manage the risks of initiating infrastructure projects without a fully mature programme design, and plan using appropriate checkpoints within contracts to assess progress.

Concluded (the committee's words)
The Department’s previous contracts have been poorly designed, which has left the taxpayer to shoulder the burden of cost increases while doing little to incentivise contractors to improve performance. The defence nuclear field is a monopoly environment and very few companies are able to carry out such work; four contractors hold 97% by value of the Enterprise contracts. The Department says that the defence sector has become increasingly concentrated in a small number of companies. The 1958 Mutual Defence Agreement also means that only Rolls Royce has the capacity to design and manufacture nuclear propulsion systems.

Concluded (the committee's words)
The contracts for the three infrastructure projects did not allow the Department to share the financial risk. This means the taxpayer has borne the full cost of budget overruns, including those of its sub-contractors. The Department accepts the National Audit Office’s criticism that its contracts were not well designed and says it would not operate in this way in the future. The Department tells us that a number of steps have been taken to ensure it has more appropriate contracting mechanisms 6 Defence Nuclear Infrastructure and avoid repeating these mistakes. For example, before any contract is let by a primary contractor for Dreadnought work, it is scrutinised by a new contracts permissioning group chaired by the Submarine Delivery Agency Chief Executive. In addition, around £37 billion of contracts—some 252 in total—are now subject to the Single Source Contract Regulations (the Regulations), which the Department says have helped increase transparency over costs. However, so far it has been unable to persuade Rolls Royce to agree to move the Core Production Capability contract to come under the Regulations. Recommendation: In the 2020 report to Parliament on the Dreadnought programme, the Department should update us on how it is taking full advantage of the Single Source Contract Regulations, making full use of target cost or firm price contracts, and ensuring that it effectively shares risk with site owners when negotiating commercial arrangements.

Concluded (the committee's words)
The current funding regime does not work for the Nuclear Enterprise due to its uniquely long project timescales, and given the impact on the stretched overall defence budget. Instead, there is a strong case for ring-fencing the nuclear budget. The nuclear budget is around 18–19% of the UK defence budget, whereas it is 6–7% of the defence budget of the United States. The Department says it currently has the funding it needs, but will negotiate with the Treasury about future funding as part of the Spending Review. Under current arrangements, the nuclear budget remains subject to the same pressures as other expenditure. The Department is keen to place some form of ring-fence around the nuclear budget, given its high priority and importance.

Concluded (the committee's words)
The Department finds that the demands of Treasury annularity expectations and managing to a 31 March deadline are hard for long-running major capital programmes. The need to achieve in-year affordability savings has had some terrible consequences, such as work being deferred, which in the case of MENSA has led in the past to increased costs, with AWE receiving additional fees as part of a £97 million cost increase. It has embarked on a huge programme of recapitalisation across the whole Nuclear Enterprise, involving new nuclear submarines, new propulsion systems and new infrastructure, many of which will be in the top ten largest for the Department. As a result, there are peaks of spending in the coming years, at a time when, as the Committee has reported on a regular basis, the overall defence budget is stretched. This emphasises the importance of managing the portfolio of programmes as a whole, trying to smooth spending and managing the overall risk profile. Recommendation: Given its impact on the overall defence budget, the Department should make a case to the Treasury for ring-fencing the nuclear budget in the course of the discussions in 2020 for the current Integrated Review and the Spending Review.

Concluded (the committee's words)
The Department has belatedly learned through experience the importance of strong relationships between it, the nuclear regulators and the site owners. This has been a missed opportunity to improve mutual understanding and tackle challenges, to the detriment of the Nuclear Enterprise. Regulatory arrangements for nuclear sites involve the Department, the site operators and one or both nuclear Defence Nuclear Infrastructure 7 regulators, depending on whether the Department or industry own the site. The Department must pay for the infrastructure it needs, but it is the site operator that holds the nuclear licence and must satisfy the regulators’ requirements. Because the Department does not operate most of the nuclear-regulated sites, it does not hold a regulatory role. All parties accepted that some ‘gold-plating’ of specifications had taken place, although the Department does not consider that the regulators try to force expensive facilities on it.

Concluded (the committee's words)
More recently, the Department says there has been improved dialogue via senior leadership groups which bring together different responsible parties at Devonport and AWE sites. We commend this continuous learning from experience. A Defence Nuclear Organisation team is also now located on site at MENSA and there is a shared cost management system to share schedule and cost data in real time. The Department says that the Office for Nuclear Regulation has been happy to discuss costs and help avoid ‘gold-plating’ of specifications. It is also confident that there are many issues around the design and build that it can continue to discuss with the regulatory community, which do not require any changes to the current arrangements. Recommendation: To secure performance improvements across infrastructure programmes, the Department must continue the commendable practice of admitting failures early and learning from its mistakes. We expect to see as standard more robust liaison arrangements between the Department, site owners and regulators, including the use of co-location of teams, consistent with practice in the civil sector to accelerate the process of reviewing and learning.

Concluded (the committee's words)
It is unacceptable that the Department in other areas has repeated past mistakes, and has failed to learn lessons from elsewhere. This underlines the importance of developing a strong corporate memory and retaining experienced staff wherever possible. Many of the mistakes made on these projects are similar to those on which the Comptroller and Auditor General reported more than 30 years ago, and have also been seen in the civil nuclear sector and in the United States. The Department cannot explain why its leadership has not ensured that it learned from these experiences, started before requirements were sufficiently mature, and had not engaged sufficiently with the regulators in the past. It accepts that the NAO report contains a full set of lessons and that it should not operate in the same way in the future.

Concluded (the committee's words)
The failure to learn from the past underlines the importance of the Department maintaining a robust corporate memory, particularly given that specialist staff are in demand and may move to posts elsewhere in government and the private sector. The creation of the Defence Nuclear Organisation was in part designed to consolidate knowledge in one place, and the recently appointed Director-General Nuclear stated that she had specialists with 20–30 years of experience, but there are personnel shortages. The Permanent Secretary states that he wants a mix of internally developed staff and external expertise, and that itis important that the Department is able to generate its own talent. The Department continues to discuss how to improve the position on specialist skills with the Department for Business, Energy and Industrial Strategy and the Department for Education. 8 Defence Nuclear Infrastructure Recommendation: Given the specialist nature of this field, it is essential that the Department has in place effective arrangements to maintain corporate memory, and works with industry and other government departments to develop the skills needed to be able to take forward nuclear work in line with best practice. The Department should update us on the progress it is making in this regard in the 2020 report to Parliament on the Dreadnought programme.

Concluded (the committee's words)
Ultimately, the Department retains the risk associated with these programmes and must manage them itself, regardless of whether it owns the relevant sites or not. The Department uses eight nuclear-regulated sites. It owns and operates two of them, with contractors owning or operating the others. The Department acknowledges that the scale of the risks of nuclear programmes, civil or military, means they are too large for private companies to carry and the risk of failure or cost overruns rests with the state, regardless of ownership. The Department accepts that contracts it had signed in the past have not reflected this reality as well as they should have done.

Concluded (the committee's words)
On whether it is considering taking on the risk directly and then contracting out the facility to a private company, the Department responded that it is considering where ownership of risk should lie for future projects. We are also concerned that when the Department makes a contract it does not at least jointly own the intellectual property. The Department says that it makes a balanced decision about who should own or use the facilities and intellectual property. Sometimes the contractors have the intellectual property that the Department wishes to benefit from, and on other occasions, the Department generates it. Recommendation: The Department must avoid writing contracts which purport to transfer risk to the private sector when in reality this is illusory. The Department must only write contracts which are explicit about where risks lie and how those risks will be monitored and managed by both the Department and the contractor. The Department should write to us by 31 December 2020 to provide a detailed assessment of whether the current ownership arrangements for nuclear regulated sites are in the best interests of the taxpayer and whether more could be done to exploit the intellectual property arising from developments on the sites in the national interest.

Concluded (the committee's words)
The contracts the Department prepared did not allow it to share the financial risk, which meant that it bore the full impact of cost increases, including those of its sub-contractors. For example, at Barrow, BAE Systems received a £65 million increase in claims from its subcontractor, which were passed on to the Department. Under the contract, BAE Systems also got an increase in its management fee, which rose along with the costs incurred.19 We pointed out that our predecessors had criticised the Department for cost-plus based contracts almost thirty years ago.20 Improving commercial arrangements

Concluded (the committee's words)
The Department accepted the National Audit Office’s criticism that its contracts had not been well designed in the past and said it would not operate in this way in the future. It told us that a number of steps had been taken to ensure it had more appropriate contracting mechanisms and to expunge some past practices.21 For example, before any contract is placed by its main contractors for Dreadnought work, it is scrutinised by a new contracts permissioning group chaired by the Submarine Delivery Agency Chief Executive to see what is to be delivered down the delivery chain.22 The Department said it had also made improvements to supply chain management, with 85% of contracts for MENSA moved to a fixed cost or target cost forecast basis.23

Concluded (the committee's words)
In addition, around £37 billion of contracts—some 252 in total—are now subject to the Single Source Contract Regulations (the Regulations), which the Department stated had helped increase transparency over costs and strengthened the Department’s position. However, although Rolls Royce had signed up to the Regulations for new contracts, so far the Department had been unable to persuade it to agree to move the Core Production Capability contract to come under the Regulations. This is subject to commercial negotiations.24 More generally, the Chief Executive of the Submarine Delivery Agency said that the body was significantly strengthening supervision and oversight of its contracts, and was recruiting people with greater contract management experience.25 18 Q 80 ; C&AG’s Report, para 3.2 19 Q 75 ; C&AG’s Report, para 3.6 20 Qq 70, 79 21 Q 79 22 Q 74 23 Q 61 24 Qq 76, 82 25 Q 85 Defence Nuclear Infrastructure 13 3 Improving future performance Relationships with the regulators

Concluded (the committee's words)
Because of the risks associated with defence and civil nuclear sites and the handling of nuclear material, they are subject to strict regulation. When constructing new facilities, the site operator is usually required to obtain the regulators’ agreement that the design and construction meet safety and regulatory requirements. Safety cases will include detailed information on the material used, how the facility has been built to required engineering standards, the requirements for examination and testing of equipment, and evidence that nuclear risks have been reduced as far as possible.26

Concluded (the committee's words)
Regulatory arrangements for nuclear sites involve the Department, the site operators and one or both nuclear regulators. The Office of the Nuclear Regulator licenses defence sites operated by third parties. The Defence Nuclear Safety Regulator oversees sites owned and operated by the Department. The Department must pay for the infrastructure it needs, but it is the site operator that holds the nuclear licence and must satisfy the requirements of the regulator. Because the Department does not operate most of the nuclear-regulated sites, it does not hold a regulatory role and as a result has been less able to influence value for money.27 The National Audit Office reported that all parties accepted that some ‘gold- plating’ of specifications had taken place, such as over-engineered blast doors at MENSA.28

Concluded (the committee's words)
The Department said that the importance of improved relationships with the regulator was one of the three most important lessons it had learned from these projects.29 In response to past problems, it had improved the dialogue via senior leadership groups which brought together different responsible parties. At Aldermaston, this was the A6 group and at Devonport, the D6. These groups discussed regularly how projects were progressing and were designed to involve regulators early.30

Concluded (the committee's words)
The Department considered that the more the different parties worked together, the greater likelihood that money would be well spent, and the Chief Executive of the Submarine Delivery Agency confirmed that all future infrastructure projects would take as joined-up an approach to planning as possible.31 A Defence Nuclear Organisation team is also now located on site at MENSA and there is a shared cost management system to share schedule and cost data in real time.32

Concluded (the committee's words)
We asked the Department whether the current regulatory model was the best way of working. It said it was not contemplating constitutional changes to regulatory arrangements and there was much learning possible with the regulatory community that did not require such change. There was now a good, constructive dialogue with the regulators, and at Devonport, for example, the Department stated that substantial costs had been taken from future infrastructure plans as a result of working with the regulators to make a quite radical improvement.33 It added that ONR did not try to make the Department choose the 26 C&AG’s Report, para 1.9 27 C&AG’s Report, para 2.5, Figure 7 28 C&AG’s Report, para 2.7 29 Q 66 30 Q 58 31 Q 58 32 Q 60 33 Qq 92–93 14 Defence Nuclear Infrastructure most expensive facilities and were pragmatic and reasonable.34 The importance of a corporate memory and skills

Concluded (the committee's words)
Many of the mistakes made on these infrastructure projects were similar to those on which the National Audit Office and the Committee have reported in the past, and have also been seen in the civil nuclear sector and in the United States.35 The Department could not explain why it had not learned from these experiences, and had started building before requirements were sufficiently mature. It also could not explain why it had taken so long to identify the problems at MENSA between 2013 and 2015. It fully accepted the NAO conclusions and recommendations, and said it would not operate or contract in the same way in the future.36

Concluded (the committee's words)
The failure to learn from the past underlines the importance of maintaining a robust corporate memory within the Department, particularly given that its specialist staff are in demand and may be expected to move to posts as part of the normal churn of government. The creation of the Defence Nuclear Organisation in 2016 was, in part, designed to consolidate knowledge in one place. We asked the Director-General Nuclear how she ensured an accumulation of institutional memory. She told us there was deep expertise within the organisation, not least the Submarine Service, as well as amongst weapons and nuclear scientists. Some had 20–30 years of experience, but the Department was also developing new staff and bringing people in from outside the organisation.37 A nuclear strategic workforce planning project was established in spring 2019 and is identifying necessary actions to address skills gaps.38

Concluded (the committee's words)
Despite this, there are shortages of personnel with crucial specialist skills. The Department noted, for example, there was a lack of those able to write safety cases, which contain the information the regulators need to be able to draw evidence-based conclusions on whether nuclear standards have been met.39 The Permanent Secretary told us that he wanted a mix of internally grown staff and external expertise, but thought it was critical that the Department thought carefully about its talent management and developed its own people.40 He said that the Department wrestled with the challenge of having sufficient specialists but there were not as many as the country needed. He continued to discuss how to improve the position with the Department for Business, Energy and Industrial Strategy and the Department for Education.41 Ownership of the sites

Concluded (the committee's words)
The Department uses eight nuclear-regulated sites. It owns and operates two of them, with contractors owning or operating the others.42 We asked the Department whether it was considering taking on the risk and owning some of the assets that are currently held by site operators directly. The Department acknowledged that the scale of the risks 34 Q 102 35 C&AG’s Report, Figure 11, para 3.19 36 Qq 60, 70–71 37 Q 68 38 Letter from Sir Stephen Lovegrove, 25 March 2020 39 Q 104 40 Q 67 41 Q 99 42 C&AG’s Report, para 1.3 Defence Nuclear Infrastructure 15 of nuclear activity, civil or military, means these risks are typically too large for private companies and ultimately rested with the state, regardless of ownership. It accepted that historically the contracts that it had signed had not reflected this reality as well as they should have done, and some of the current tensions arose from that. The Department told us that consideration was being given to where ownership should lie for future projects, aligning it more closely with the real adoption of risk by the Department. It was harder to change existing arrangements, where it was bound by contract law. It did, however, have ‘step-in’ rights if needed.43

Concluded (the committee's words)
We asked the Department about the ownership of intellectual property where it is not the site owner, and why, when it had contracted, it did not at least jointly own the intellectual property. The Department said that it made a balanced decision about who should best own or use the facilities and intellectual property. Sometimes the contractors have the intellectual property that the Department wished to benefit from, and on other occasions, it generated it.44 43 Qq 89–90 44 Qq 82–84 16 Defence Nuclear Infrastructure
