Advanced Modular Reactors: Criticality Tests

Debate between Viscount Hanworth and Lord Callanan

Tuesday 19th March 2024 Lords Chamber

[Viscount Hanworth]

To ask His Majesty’s Government what assistance they provide to the developers of advanced modular reactors to enable them to conduct criticality tests.

[The Parliamentary Under-Secretary of State, Department for Energy Security and Net Zero (Lord Callanan) (Con)]

My Lords, advanced modular reactors hold significant potential to decarbonise hard-to-abate sectors. As part of the advanced modular reactor research, development and demonstration programme, the Government are exploring what further underpinning research and development is required, such as critical assembly tests for fuel, to demonstrate the abilities of high-temperature gas reactors. The Government are committed to building on our existing support for the sector and, as part of the alternative routes to market for new nuclear projects consultation, we are seeking views on how we can go further to unlock these opportunities.

[Viscount Hanworth (Lab)]

I thank the Minister for that Answer. Several projects aimed at developing advanced fourth-generation modular reactors are under way in the UK, but they are wilting through a lack of the support that should be forthcoming from the Government. They require licences and test facilities in order to prove their designs. All the leading projects are seeking foreign affiliations and may be lost to this nation. Would the Government be happy to rely on foreign enterprises to provide the next generation of nuclear technology, to the detriment of our own nuclear industry?

[Lord Callanan (Con)]

Of course we would not, which is why we are offering support for many of these technologies. The noble Lord’s Question asked about criticality tests—we are aware of that requirement and are in discussions with a number of companies interested in carrying them out in the UK, but these are not simple issues.

Civil Nuclear Road Map

Debate between Viscount Hanworth and Lord Callanan

Monday 15th January 2024 Lords Chamber

[Viscount Hanworth (Lab)]

My Lords, the road map makes frequent reference to high-temperature gas-cooled reactors. An indigenous project to build such a reactor, called U-Battery, was shelved due to a lack of government support. From whom do the Government propose to import such technology—which, by the way, was pioneered in Great Britain? When will the Government give sufficient support to our native industry, which was once pre-eminent in the world?

[Lord Callanan (Con)]

The noble Viscount makes an important point. We had one of the most pre-eminent nuclear industries, but that industry was left to die during a number of Governments, particularly starting with the Labour Government in 1997. Now we are on a different page. There are a whole host of different new technologies and processes coming forward in this space, and it is very much the job of Great British Nuclear to guide us in the process of selecting the best technologies to take forward.

Electricity: Decarbonisation

Debate between Viscount Hanworth and Lord Callanan

Wednesday 21st December 2022 Lords Chamber

[Lord Callanan (Con)]

We will be setting out further plans on the matter in due course. I remind the noble Baroness that, during 2021, almost 55% of electricity generated in the UK came from low-carbon sources. We have an ambitious target of rolling out 50 gigawatts of offshore wind by 2030, and we have an excellent record in this area.

[Viscount Hanworth (Lab)]

Have the Government thought further about small modular nuclear reactors, which could come online much sooner than the EPR nuclear reactor proposed for Sizewell? Moreover, SMRs could have significant export potential if they were to materialise in good time.

[Lord Callanan (Con)]

The noble Viscount is absolutely right—SMR technology is something that we are supporting. We have given hundreds of millions of pounds-worth of support to Rolls-Royce, which is looking actively at how it can roll that out. It has great potential for the future, both in this country and in its export capacity.

Small Modular Nuclear Reactors

Debate between Viscount Hanworth and Lord Callanan

Tuesday 28th June 2022 Lords Chamber

[Viscount Hanworth]

To ask Her Majesty’s Government when, and under what circumstances, they will place orders for small modular nuclear reactors.

[The Parliamentary Under-Secretary of State, Department for Business, Energy and Industrial Strategy (Lord Callanan) (Con)]

My Lords, the energy and security strategy sets out our intention to take one nuclear project to final investment decision in this Parliament and two projects to final investment decision in the next, including SMRs. As with any government decision, this will be subject to value for money, relevant approvals and technological readiness and maturity.

[Viscount Hanworth (Lab)]

I am not reassured by the Answer the Minister has given. To await the completion of a generic design assessment of a proven technology is to impose an unnecessary delay. There is an international market awaiting small modular reactors. Unless the Government provide full and immediate support for the SMR of Rolls-Royce, foreign producers will capture the market and we may have to depend on them for the reactors we will need to install in the UK. Does the Minister regard that prospect, and the prospect of losing overseas markets, with equanimity?

[Lord Callanan (Con)]

We are providing immediate support to Rolls-Royce to develop the SMR; we provided it with £210 million to do exactly that. However, it is important that we go through all the relevant design approvals to make sure that SMRs are safe and easy to deploy. That is an important step to go through and which is legislated for in this country, and we should make sure that we follow it.

European Research Council

Debate between Viscount Hanworth and Lord Callanan

Wednesday 27th April 2022 Lords Chamber

[Lord Callanan (Con)]

My noble friend makes a very good point. We think on balance that it is worth associating with the Horizon programme, which is why we agreed to participate, paying our full amount into it of course for that participation. However, if the EU refuses to stand by the agreements that it signed, we will put alternative arrangements in place, and all the sums that would have been allocated to researchers under the Horizon programme will instead be funded directly by the UK.

[Viscount Hanworth (Lab)]

My Lords, we should soon be admitted to the Horizon Europe programme for funding research and innovation if the Government were to undertake not to invoke Article 16. However, what progress can the Government report in their endeavour to seek collaborative research arrangements with other countries, in particular with the Swiss, who have also not been readmitted to Horizon?

[Lord Callanan (Con)]

The noble Viscount makes a very good point and, of course, alludes to the previous answer that I gave to my noble friend Lord Hannan. There are many good universities around the world, not just necessarily in the EU. We have a number of different, collaborative research programmes with other parts of the world. Ironically, under the Horizon programme, it is of course possible for third countries to associate in collaborative research programmes, provided they pay their fair share of the bills. The EU is not just treating us unfairly in terms of the agreement it signed, but is actually treating us differently from other countries in the world.

Mathematical Sciences

Debate between Viscount Hanworth and Lord Callanan

Tuesday 8th February 2022 Lords Chamber

[Lord Callanan (Con)]

I think boys like fun as much as girls do—sometimes even together. I am delighted to hear about all the excellent leading women who are in top-level positions. We, as the males in this world, will clearly have to do better to compete with their excellent record.

[Viscount Hanworth (Lab)]

My Lords, the demise of mathematics in British universities is a direct consequence, albeit inadvertent, of the Government’s policies. The Government have allowed universities to compete for students without limit in pursuit of enhanced student appreciation, which can affect student recruitment. In order to accommodate students of lesser academic ability, the universities have relieved many of their courses of the burden of mathematics. This is damaging our prospects as a technological nation. Have the Government envisaged any means of limiting this harm?

[Lord Callanan (Con)]

I am afraid that I just do not recognise the picture the noble Lord is painting. The UK is a world leader in mathematical science and British mathematicians publish a large volume of highly regarded work. We have the fifth largest share of publications in the world. When looking at the top 1% of the most cited publications, UK mathematicians are responsible for the third largest share. I am sure we could always do more and better, but we have an excellent record.

Net Zero Test

Debate between Viscount Hanworth and Lord Callanan

Thursday 22nd July 2021 Lords Chamber

[Lord Callanan (Con)]

I agree with the noble Lord on the important contribution that agriculture makes and will need to make in the fight against climate change. Defra is looking at ways to reduce agricultural emissions and is progressing its environmental and land management schemes. It is also looking at other options to reduce agricultural emissions, including some very innovative solutions on the use of, for instance, methane-inhibiting food additives.

[Viscount Hanworth (Lab)]

In Monday’s debate on transport decarbonisation the Minister said:

“The more we can set out … what our expectations are, the more we expect that development to increase.”—[Official Report, 19/7/21; col. 26.]


The Government’s wish list is unsupported by effective plans for action. A yet to be published report of the Science and Technology Committee that deals with the means of transport decarbonisation has stated that the Government’s actions do not align with their ambitions to achieve net-zero emissions. What is required is an independent office for climate responsibility, which can assess the extent to which the Government’s actions correspond with their stated objectives. Do the Government recognise this need?

[Lord Callanan (Con)]

I understand the point the noble Lord is making, but I would refer him to the independent Committee on Climate Change, which does many of the things he is suggesting. It was established by the Climate Change Act 2008 and provides expert advice to the Government on climate change mitigation and adaptation. As he will have seen in its written reports, it is not afraid to point out what it sees as any deficiencies.

Steel Sector

Debate between Viscount Hanworth and Lord Callanan

Monday 12th July 2021 Lords Chamber

[Lord Callanan (Con)]

The noble Lord makes a very good point about the high energy costs. We have provided more than £550 million in relief to the steel sector since 2013 to make electricity costs more competitive. Of course, we continue to keep the matter under review and to have discussions with the sector.

[Viscount Hanworth (Lab)]

If Britain is to have an industrial future, it needs a domestic steel industry. It needs a low-carbon industry to replace one that is a large emitter of carbon dioxide—as are the foreign industries from which we have been importing increasing quantities of steel. To create a low-carbon industry which employs electric arc furnaces and uses hydrogen as a reducing agent requires considerable investment. It also requires protection from foreign competition by a stringent carbon tax. Are the Government prepared to overcome their usual reluctance by providing funds for this investment? Are they prepared to impose such a carbon tax on imported steel?

[Lord Callanan (Con)]

We have supported the steel sector extensively over the years and I outlined some of the money that we have spent. The noble Viscount will know that decisions on taxes are of course a matter for the Chancellor. I am sure that if there are any actions, he will hear of them directly from the Chancellor.

Rolls-Royce

Debate between Viscount Hanworth and Lord Callanan

Wednesday 14th October 2020 Lords Chamber

[Lord Callanan (Con)]

I totally understand and sympathise with the points that the noble Lord is making, but Rolls-Royce is a global company and it is having to make some very difficult decisions about its footprint everywhere as demand for its products and services has fallen significantly in the current pandemic. As I said, we are offering significant support to it and other aerospace companies.

[Viscount Hanworth (Lab)]

My Lords, as has already been said, the closure of the plant at Barnoldswick and the assignment of its activities to a factory in Singapore would devastate a highly skilled workforce. I fear that it would also pose a threat to the intellectual property of the company and the nation. Will the Government take steps to ensure that that does not happen? Will they also seek to sustain the company in the face of its financial difficulties by commissioning high-tech projects that will assist the process of decarbonisation?

[Lord Callanan (Con)]

The noble Viscount makes a very good point. We are working closely with the company to ensure that the UK remains at the heart of its operations, and we are currently supporting the development of the next generation of engine through the ATI programme, as well as discussing longer-term possibilities around new, clean aviation technologies.

Energy White Paper

Debate between Viscount Hanworth and Lord Callanan

Monday 28th September 2020 Lords Chamber

[Viscount Hanworth (Lab)]

One requirement in decarbonising the economy will be the replacement of current aviation fuels with hydrogen-based synthetic fuels, which will be produced by an energy-intensive process. Aero engines will also need to be adapted to consume such fuels. Small modular nuclear reactors, which Rolls-Royce is developing, would be a means of supplying the necessary energy. The company is also at the forefront of the aero engine industry. Do the Government recognise the unique opportunity that exists in sponsoring Rolls-Royce to pursue developments on both these fronts?

[Lord Callanan (Con)]

We are always willing to work with innovative British companies. I agree with the noble Viscount’s points about hydrogen and advanced nuclear technologies, which we are providing considerable support for.

Energy: Hydrogen

Debate between Viscount Hanworth and Lord Callanan

Thursday 17th September 2020 Lords Chamber

[Lord Callanan (Con)]

The noble Lord is entirely correct. He makes a very good point that this is an important new developing technology that we will want to support as much as we can. The UK is well placed to play a leading role in all the areas that he mentions, and when the hydrogen strategy is published it will take account of all those factors.

[Viscount Hanworth (Lab)]

I understand that most of the hydrogen that is consumed in the UK is generated by the steam reformation of methane, whereby one molecule of methane and one of water produce three molecules of hydrogen and one of carbon monoxide, which rapidly becomes carbon dioxide. The process is therefore by no means carbon neutral. Moreover, it requires a substantial input of energy, which at present is liable to come from fossil fuels. Are the Government prepared to insist that in future the supply of hydrogen will be produced by electrolysis? Will they also take steps to ensure that there will be a regular supply of carbon-neutral electricity sufficient for the purpose? Can we be assured that the hydrogen strategy has a purpose beyond that of supplementing our dwindling supplies of natural gas?

[Lord Callanan (Con)]

The noble Viscount is of course referring to the different kinds of hydrogen, referred to as green and blue hydrogen. We take the view that both will be needed to meet the UK’s potential hydrogen demand by 2050. Blue hydrogen has a role to play in producing cost-effective low-carbon hydrogen at scale, but of course we will need to use carbon-capture technology along with it.
