Advanced Modular Reactors: Criticality Tests

Viscount Hanworth Excerpts

Tuesday 19th March 2024 Lords Chamber

Asked by

[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.
