ASN meaning

In legal and regulatory practice, ASN refers to France’s nuclear safety authority (Autorité de Sûreté Nucléaire), the national nuclear safety and radiation protection regulator. Under French law, ASN is an independent authority overseeing nuclear installations and the use of ionising radiation in medicine, industry and research. It sets requirements, licences activities, inspects and enforces, and informs the public, with the aim of protecting workers, patients, the public and the environment. For UK and Irish practitioners, the term commonly arises in cross‑border compliance, procurement and transactional work involving French nuclear sites, radioactive sources or medical exposure, and in incident reporting and transport matters. ASN has no jurisdiction in the UK or Ireland; its decisions and guidance apply in France but are often incorporated by reference in contracts and supply‑chain standards. Usage is consistent across England & Wales, Scotland, Northern Ireland and Ireland: it denotes the French nuclear regulator. The acronym is not defined in UK or Irish legislation; it is defined and governed by French legislation and is used descriptively in UK and Irish legal contexts.
