Question to the Department for Energy Security & Net Zero:

To ask His Majesty's Government how many universities in England have small nuclear reactors that are being used to develop or apply radiotherapy medical treatment.

There are currently no universities in England that have small nuclear fission reactors that are being used to develop or apply radiotherapy medical treatment.

It is critical that the UK continues to maintain access to the nuclear medicines it needs. In the 2024 Civil Nuclear Roadmap, the government committed to considering a research reactor and an accelerator in the next Spending Review to address the UK’s supply needs.

No decisions have yet been taken by the government to select one or more technology options.
