USA based vendor of SMR technology with each of 12 possible units rated at 45 MWe.

Nuclear Advanced Manufacturing Research Centre: Works with companies along the UK civil nuclear manufacturing supply chain, combining the manufacturing and engineering expertise of the University of Sheffield with the nuclear and materials capacity of Dalton Nuclear Institute at the University of Manchester.

Concrete for the construction of the nuclear island, usually a key Regulatory Hold Point during construction of an NPP.

The Nuclear Decommissioning Authority (NDA) has published its SME action plan 2027–28, setting out how the NDA group will improve access for small and medium-sized enterprises (SMEs) to procurement opportunities and target 9% direct SME supply chain spend in the 2027/28 financial year. The plan focuses on increasing visibility of opportunities, supporting prompt payment, embedding SME-related benefits in procurement processes and using Procurement Act 2023 flexibilities to reserve below-threshold procurements for SMEs where appropriate. The NDA also states that it will publish pipeline notices on Find a Tender by 26 May each financial year and continue supplier engagement through events, forums, workshops and its Atamis eSourcing platform.

The energy released by a nuclear reaction (either fission or fusion) or by radioactive decay.

Uranium or plutonium which has been fabricated into pins, assemblies, plates, or other such similar form for the purposes of fuelling a nuclear reactor. Other High-Z elements are capable of being used as nuclear fuel (e.g. thorium). For fusion reactors.

Established by the NDA and supported by a range of employers the Nuclear Graduate Programme is for those looking to enter the nuclear industry but wishing to work with a variety of employers in the sector to develop a broad knowledge and understanding of the sector through a range of placements.

The Nuclear Installations Act 1965: The NIA 1965 is the principal piece of UK legislation implementing the Paris Convention and Brussels Convention in the UK and sets out statutory provisions for nuclear liability and licensing of nuclear installations.

Nuclear Island: That part of an NPP which incorporates all equipment, systems, installation and control and other relevant hardware installed within the reactor and reactor auxiliary buildings. The boundaries of the NI are normally defined as being one metre outside the external boundaries of the above mentioned buildings in the case of piping and two metres for cable. An NPP is divided into two main parts i.e. the nuclear island and the conventional island. The nuclear island is further sub-divided into the NSSS and the balance of nuclear island i.e. everything else that needs to be designed, constructed and tested to complete the nuclear island.

The strict legal liability of a Nuclear Site Licence holder for all nuclear damage as defined under the Nuclear Installations Act 1965.

A whole lifecycle approach to a nuclear power project consisting of several phases: R&D, Conceptual Design, Detailed Design, Construction, Commissioning, Operations and Maintenance, Refurbishment or Life Extension (if applicable) and Decommissioning.

A process by which the spread of nuclear weapons technology is prevented. See also the Treaty on the Non-Proliferation of Nuclear Weapons.
