Small Modular Reactors and Energy Security

Robin Millar Excerpts

Wednesday 19th January 2022 Westminster Hall

[Virginia Crosbie]

I thank the hon. Member for his intervention. I am looking forward to an invitation to visit Caithness and see at first hand how important hydrogen is, how it can be linked with nuclear and how we can, I hope, come up with pink hydrogen. In my constituency of Anglesey, we are fortunate to be developing the Holyhead hydrogen hub, which the hon. Member might like to visit.

With much of the European gas supply transiting the continent through central and eastern Europe, the UK and other western European nations are at risk of Russian action to influence the price of wholesale gas and supply through Russian pipelines. Worse still, many of the other sources of gas for heating and industry also come from unstable parts of the globe. The UK is facing an existential crisis in energy supply that ultimately leaves the country exposed to soaring energy costs and potential electricity blackouts if we are unable to secure affordable, home-grown energy long term.

Addressing our energy needs is an urgent priority for the UK. We must build our way out of this overreliance on foreign energy by developing our indigenous supply in a way that is compatible with our COP26 and net zero commitments. To meet the requirements of the sixth carbon budget, we will need all new cars, vans and replacement boilers to be zero carbon in operation by the early 2030s. To move people towards the use of electricity while hitting net zero production by 2035, we must quickly move away from generating that electricity from fossil fuels. Britain currently has slim spare capacity in electrical power generation to feed those changes, leaving both our energy supply and our security under threat.

There is an obvious solution on the horizon. Nuclear power, which has been a neglected part of our energy mix, can bridge the gap. SMRs provide a once-in-a-generation opportunity for the UK to develop a new, global industry sector that will contribute to the country’s long-term energy security. A single SMR located on Anglesey in my constituency could produce enough energy for the whole of north Wales, which is primarily rural. A large plant in the same location could power the whole of Wales—with a little bit left over for England, if we are feeling generous.

Not only are SMRs easier to finance, but a factory build in controlled conditions means that they could be up and running as soon as 2028.

[Robin Millar (Aberconwy) (Con)]

My hon. Friend is making an excellent speech about how SMRs are of value not just to the UK, but beyond its shores. In Aberconwy I talk to farmers—they are the custodians of some three quarters of the constituency, and they produce some of the finest lamb and beef in the world—and I am hearing from them already that the impact of energy costs mean that bills are rising by up to £1,000 a month. Will she urge the Minister to meet with farmers and farmers’ representatives in Wales to make sure that is taken into consideration in looking at the energy supply?

[Virginia Crosbie]

My hon. Friend and neighbour from the beautiful constituency of Aberconwy makes a very important point. In his previous roles, the Minister has been keen to reach out to the farming community. He has already committed to coming to visit Anglesey and Wylfa Newydd, and I am sure he will reach out to the important rural and farming communities as part of that visit.

When it becomes law, the Nuclear Energy (Financing) Bill will give developers a guaranteed return on their investment and lower the cost of raising the capital required to build a power station; that accounts for much of the cost of nuclear projects. We have already seen the regulated asset base model used for infrastructure projects in London, such as the Thames Tideway tunnel, and using it in Wales to finance new nuclear will make a big difference in levelling up the UK.

There has been rapid progress in recent months. Rolls-Royce has received the green light to develop its SMR technology, with match funding from the UK Government. The Nuclear Energy (Financing) Bill will also make a big difference in allowing new sources of funding for nuclear projects. There are other exciting SMR technologies that can help the UK reduce its dependence on expensive foreign energy.

The generation IV molten salt reactors developed by Terrestrial Energy not only have the potential to provide clean energy to the grid, but could provide scalable clean hydrogen for industry. Boiling water reactors, such as that developed by GE Hitachi, deliver clean, flexible baseload energy, too. There is a real opportunity for the UK to take a lead in this field, supported by engineering firms such as Assystem and Bechtel, as well as the wider UK supply chain, which can support the development of all different types of SMR reactors.

This Government have made some impressive funding commitments so far, with the recent Budget allocating £1.7 billion of public funds to support new nuclear projects. The Government have committed to £385 million in the advanced nuclear fund, £215 million for small modular reactors, £170 million for research and development on advanced modular reactors and £120 million for the enabling fund announced in the net zero strategy. Finally, there is an additional £40 million for developing regulatory frameworks and supporting UK supply chains. That is very welcome, but given the scale of the potential energy crisis, there is scope for the Government to do more. The UK should be looking at contingency plans to get new SMRs into play as soon as possible to replace fossil fuel generation.
