Nuclear Fuels Management

Managing the lifecycle of spent nuclear fuels

What is Nuclear Fuels Management?

The lifecycle for the management of spent fuels discharged from nuclear reactors may involve a number of stages or building blocks: storage, transport, reprocessing and disposal. The management strategy for different sources and types of nuclear fuels may involve different variations and combinations of these building blocks.

Why is Nuclear Fuels Management Important?

The UK has 15 operational nuclear reactors at 7 sites, which together supply ca. 20% of the nation’s electricity. Having safe, resilient strategies for the management of the spent fuels from these reactors is essential to ensuring that the nation has a dependable supply of energy for its homes and industries. There are plans to replace some of the ageing nuclear generating capacity in the UK with new reactors, whose spent fuels will also need to be managed. In addition, the UK has a legacy of diverse spent fuels from a variety of research, prototype and power reactors that require safe, cost-effective and practical future management strategies.
