This report provides an update on UKNNL's ED&I journey for 2024-25, covering gender, ethnicity, and disability pay gaps. Our median gender pay gap has continued to narrow to 8.3%, well below the nuclear industry average of 18.9%, driven by improved representation of women in senior roles. This year, we introduce our disability pay gap for the first time, which shows no opportunity bias, though the lived experience of colleagues with a disability requires further attention. Our ethnicity pay gap remains at 8.3%, with ongoing recruitment bias requiring targeted action. While progress has been made, we recognise there is more to do and remain committed to building a truly inclusive workplace for all.

As the UK's lead civil national laboratory for nuclear fission, UKNNL reinvests its earnings into research and development that addresses some of the most pressing challenges in nuclear decommissioning — from robotics and AI-assisted remote operations to advanced waste treatment and geological disposal. The report details progress across seven Core Science Themes, alongside strategic research programmes, university collaborations, and investment in facilities, infrastructure and people.

This is the UK National Nuclear Laboratory (UKNNL) annual Earnings to Reinvest report, highlighting significant progress in environmental restoration and nuclear facility clean-up operations during the 2023/24 financial year.

The report showcases how UKNNL's reinvestment of earnings has advanced scientific and technological capabilities in nuclear decommissioning, through collaborative partnerships with key organisations including Sellafield Ltd, and the Nuclear Decommissioning Authority (NDA).

NNL is committed to using its earnings to reinvest in science and technology to bring benefit to society. Each year, we produce the Public Interest Reinvestment Contributions to Environmental Restoration report, which throws a spotlight on investment into people, skills, science and technology to enhance the already well-established UK capabilities in this area.
