Nuclear Fuel meaning

Published by a LexisNexis Energy expert
What does Nuclear Fuel mean?
In legal practice, nuclear fuel refers to material used to sustain a nuclear fission reaction in a reactor—most commonly uranium or plutonium that has been processed and fabricated into fuel elements (pins, rods, plates or assemblies) for loading into a nuclear reactor. It can also encompass alternative fuel cycles (for example, thorium) where prepared for reactor use. The term covers both fresh and irradiated fuel and is central to nuclear site licensing, safeguards and security controls, transport authorisations, waste management and third‑party liability/insurance. UK legislation, notably the Nuclear Installations Act 1965 and associated regimes, uses the term and related expressions (such as “irradiated nuclear fuel” and “nuclear matter”) rather than an exhaustive list of elements. Usage is broadly consistent across England & Wales, Scotland and Northern Ireland. In Ireland, statutes more commonly refer to “nuclear material” under Euratom‑aligned radiological protection and safeguards law; “nuclear fuel” is generally a descriptive term. fusion facilities use different fuels (for example, deuterium and tritium). In the UK and Ireland these are typically not treated as “nuclear fuel” for nuclear site licensing or civil nuclear liability, and are regulated under separate frameworks.

Planning and Regulatory Framework for Radioactive Waste in England and Wales: Geological Disposal (NSIPs), Non-geological Routes (TCPA), Policy, Consents, Consultation and Case Law

Scope of this Practice Note This Practice Note sets out the main types of radioactive waste and examines disposal against the EU-defined waste hierarchy. It places contemporary management of radioactive waste within the historical development of the nuclear industry from a planning standpoint. Principal policy documents are reviewed to chart the evolution of government thinking over time. Geological disposal of Higher Activity Waste (HAW) under the Planning Act 2008 (PA 2008) is compared with alternative disposal routes under the Town and Country Planning Act 1990 (TCPA 1990) and the Planning (Wales) Act 2015. Consultation duties, application processes and required consents are identified for both regimes. Notable planning appeals and judicial review cases are highlighted before looking at international approaches to radioactive waste. What is radioactive waste? In the UK, radioactive waste arises—and will arise—from past, current and future programmes for electricity generation from nuclear fission, the reprocessing of nuclear fuel, the development of nuclear weapons, the nuclear submarine fleet and wastes from radioactive materials used for civil...

For fuller analysis of the regulation, consenting and incentivisation of the net zero transition under the laws of England and Wales, see Collinson and Hockman on Energy Law: Regulating, Consenting and Incentivising the Energy Transition. That textbook explores, in depth, many of the themes addressed in this Practice Note... This Practice Note outlines the principal aspects of the supplier obligation, a mandatory charge on Great Britain’s licensed electricity suppliers used to finance the Contracts for Difference (CfD) low carbon subsidy mechanism... It also explains the reliefs available for electricity provided to electricity intensive industries (EIIs) and for power sourced from renewable generators in other EU Member States, described as ‘Green Excluded Electricity’... What is the background to the CfD regime and Electricity Market Reform? The Electricity Market Reform (EMR) programme was developed by government between 2010 and 2015 to reshape the GB electricity system and stimulate investment in secure, affordable, low carbon generation. Reform was required due to strains on a fossil fuel dependent system and...
