HNB meaning

HNB is commonly used as shorthand for the Hunterston B nuclear power station in North Ayrshire, Scotland. In legal practice it identifies the specific site, plant and associated assets in energy, infrastructure and nuclear regulatory documents. It is a descriptive term, not one defined in legislation or case law. Typical usage includes: asset sale and purchase agreements; nuclear site licence obligations under the Nuclear Installations Act 1965; health, safety and security requirements enforced by the Office for Nuclear Regulation (ONR); environmental permitting and radioactive substances regulation by the Scottish Environment Protection Agency (SEPA); grid connection and land rights; decommissioning, waste management and spent fuel contracts; and nuclear liability and insurance arrangements (including the Paris and Brussels Conventions as implemented in the UK). Hunterston B ceased electricity generation in 2022 and is in defuelling prior to transfer for decommissioning to the Nuclear Decommissioning Authority’s subsidiary (Nuclear Restoration Services) under UK Government/EDF arrangements. References to HNB should reflect this status and clearly allocate responsibilities, consents and indemnities during defuelling and subsequent decommissioning. Usage is consistent across England & Wales, Scotland and Northern Ireland; in Ireland it appears mainly in cross‑border energy, liability or transport contexts when referring to the Scottish site.
