Small Modular Reactors: Government Funding

Liz Saville Roberts Excerpts

Wednesday 7th September 2022 Commons Chamber

[Mr Ellwood]

I will make some progress, if I may.

We have Hinkley Point and Sizewell C coming online, adding 3,000 MW to the grid, but it will be a full decade before they start to add their power. We do not have the luxury of waiting that long. Energy consumption here and across the world will only increase as we move towards a cleaner fossil-free environment, especially across Africa, as economies and industries grow, placing ever greater demands on the ability to generate power.

Will the right hon. Member give way?

[Mr Ellwood]

I will make a little more progress and then give way. I know that this is an important debate.

That last point brings me to the subject that we are discussing today: Britain’s development of modular nuclear reactors. The concept is not new; Rolls-Royce has been building small reactors to power our Royal Navy submarines for decades, so one would think the UK well placed to be the first nation to have one up and running.

The benefits are very clear, and I am sure that the list will be added to in this debate. Each single reactor from Rolls-Royce generates approximately 470 MW of energy, enough to power 1 million homes. They cost only £2.2 billion each, versus the £20 billion that their bigger brothers cost. Once the first five reactors are built, the concept can be proven and we can start looking at exports. The export market for Rolls-Royce is worth £54 billion to the UK. This will not only help the UK, but help other nations to address their crippling energy prices and meet their COP26 targets.

[Liz Saville Roberts]

Trawsfynydd, in Meirionnydd, is entirely publicly owned, and is a nuclear-licensed site. As such, it offers an unparalleled opportunity for the fastest deployment of SMR technology at any UK site. The Nuclear Decommissioning Authority and the Welsh development company Cwmni Egino are working together on proposals for siting, and hopes are high that construction will begin in 2027. That is where the timing is so critical. I am sure that the right hon. Gentleman will agree that Cwmni Egino’s development model provides a blueprint, which could be used not just in Wales but beyond, for the alacrity of development that we are all seeking.

[Mr Ellwood]

I am grateful for that intervention, which confirms that there is a desire to see these reactors built here in the UK. Initially they will all be built in a single factory, which, once it is up and running, will be able to build the components in months rather than decades. Just about all the moving parts are in place to make this happen: the design, the support from the Department for Business, Energy and Industrial Strategy—represented by the Minister who will respond to this debate—the initial development costs, the private sector investment and interest, and the factory in Derby that has been earmarked, along with potential sites across the country. We would be creating 40,000 jobs and £50 billion of investment, and offering a revolution in clean energy supply.

So what is the problem? If we have a workable design, a genuine solution to help resolve this energy challenge, a Government Department saying all the right things and offering support, and backing from the private sector, why did I need to bring this issue to the Floor of the House? The answer is very simple. The Rolls-Royce design is now stuck between the development and delivery phases, and that delay means that the built-in advantage that Rolls-Royce has—its experience of procuring nuclear reactors for the Royal Navy—is being lost because of unnecessary delays and bureaucracy. Obviously all nuclear reactors are complex and there should be no short cuts to their procurement, but this is not about design approval; it is about the political will. The Government need to formally agree to commission those first five reactors here in the UK. That would allow Rolls-Royce to secure the funds to build the factory, and thus allow more reactor orders to be honoured.
