As the UK’s national laboratory for nuclear fission, NNL is harnessing nuclear science to help solve some of the world’s biggest challenges. We channel our work into four strategic areas: Clean Energy, Health and Nuclear Medicine, Environmental Restoration and Security and Non-Proliferation. These four Focus Areas are the cornerstones of our ambition, shaping what we deliver to our customers and for UK society, and how we invest in our future.

At a time when society is waking up to acting on the environmental crisis our planet faces, it is impossible to overestimate the scale of the challenge ahead for the UK in reaching net zero by 2050. Without nuclear, the UK will not meet this target on time. And without NNL’s work, the UK nuclear sector cannot deliver what is required.

We are custodians of a unique set of facilities and capabilities that enable ground-breaking nuclear research and development – including four world-leading laboratories in the North West of England. The most important asset for our future success, however, is our people. We are fortunate to be gifted with some of the most creative and inspired scientific minds in our sector, in the world.
