Arrêté INB meaning

In practice, this term denotes the French ministerial order that sets binding technical and safety rules for basic nuclear installations (installations nucléaires de base, INB). It governs the full lifecycle of an INB, including design, construction, commissioning, operation, maintenance, monitoring and surveillance, incident reporting, shutdown and decommissioning. It is legislation under French law (an arrêté), enforced by the Autorité de sûreté nucléaire (ASN). Practitioners commonly use it to refer to the general INB order made on 7 February 2012 (as amended). UK and Irish lawyers encounter the Arrêté INB in cross‑border transactions, project and supply‑chain contracts, regulatory due diligence, environmental and safety compliance, and nuclear decommissioning matters involving French sites or vendors. Contractual standards, warranties, and conditions precedent may require compliance with the Arrêté INB or evidence of conformity. The nearest UK analogue is the Office for Nuclear Regulation (ONR) site licence conditions under the Nuclear Installations Act 1965 and associated guidance; however, the Arrêté INB applies only in France. Ireland has no civil nuclear power, so references typically arise in cross‑border supply, radioactive materials handling, transport or environmental liability analysis. Usage and meaning are consistent across England & Wales, Scotland, Northern Ireland and Ireland as a foreign law term.
