Institut de radioprotection et de sûreté nucléaire
French research and expert organization
The French Institut de radioprotection et de sûreté nucléaire (IRSN) ("Radioprotection and Nuclear Safety Institute") located in Fontenay-aux-Roses is a public official establishment with an industrial and commercial aspect (EPIC) created by the AFSSE Act (Agence française de sécurité sanitaire de l'environnement et du travail – French Agency of Sanitary Environmental Security) and by February 22, 2002 decreed n°2002-254. The IRSN is placed under the conjoint authority of the Defence minister, the Environmental minister, the Industry minister and the Health and Research minister.
The IRSN gathers more than 1500 experts and researchers from the Institut de protection et de sûreté nucléaire (IPSN – Protection and Nuclear Safety Institute) and the Office de protection contre les rayonnements ionisants (OPRI – Ionizing radiations protection office). These scientists are thus competent on nuclear safety, radioactive protection and control of nuclear and sensitive materials.The IRSN realize investigations, expertise assessments and studies on the fields of nuclear safety, protection against ionizing radiation, protection and control of nuclear material, and protection against voluntary ill-advised acts.

Why this record matters
The phrase “french research and expert organization” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The record creator and administrative purpose are central evidence, because official documentation reflects both action and institutional priorities. The source revision retrieved here is dated Aug 17, 2026. The linked authority identifier is Q1502878. VIAF identifies the subject as 149182639. The Library of Congress control number is no2003081045. 2 of 4 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 2002, 1500, 2001 and 2007.
Institutional narratives can privilege the records that survived while minimizing voices that were never formally collected. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
