Annotation of standard text IEC 60951-1-ed.3.0 :
IEC 60951-1:2022 provides general guidance on the design principles and performance criteria for equipment to measure radiation and fluid (gaseous effluents or liquids) radioactivity levels at nuclear facilities during and after design basis accidents (DBA) and design extension conditions (DEC), including severe accident (SA). This document is limited to equipment for continuous monitoring of radioactivity in design basis accidents (DBA), design extension conditions (DEC), including severe accident (SA) and post-accident conditions. The purpose of this document is to lay down general requirements and give examples of acceptable methods for equipment for continuous monitoring of radioactivity within the facility during and after design basis accidents (DBA), design extension conditions (DEC), including severe accident (SA) in nuclear facilities. This third edition cancels and replaces the second edition published in 2009.The main technical changes with regard to the previous edition are as follows. - title modified. - to be consistent with the categorization of the accident condition. - to update the references to new standards published since the second edition. - to update the terms and definitions. LIEC 60951-1:2022 fournit des recommandations generales relatives aux principes de conception et aux criteres de performance des materiels utilises pour mesurer les rayonnements et la radioactivite des fluides (effluents gazeux ou liquides) dans les installations nucleaires pendant et apres les accidents de dimensionnement (DBA) et les conditions additionnelles de dimensionnement (DEC), incluant les accidents graves (SA). Le present document ne couvre que les materiels de surveillance en continu de la radioactivite utilises lors daccidents de dimensionnement (DBA), en conditions additionnelles de dimensionnement (DEC), incluant les accidents graves (SA), et en conditions post-accidentelles. Le present document a pour objet detablir les exigences generales et de fournir des exemples de methodes acceptables pour les materiels de surveillance en continu de la radioactivite utilises dans les installations nucleaires pendant et apres les accidents de dimensionnement (DBA) et les conditions additionnelles de dimensionnement (DEC), incluant les accidents graves (SA). Cette troisieme edition annule et remplace la deuxieme edition parue en 2009. Cette edition inclut les modifications techniques majeures suivantes par rapport a ledition precedente: - le titre a ete modifie. - la categorisation des conditions accidentelles a ete harmonisee. - les references aux nouvelles normes publiees depuis la deuxieme edition ont ete mises a jour. - les termes et definitions ont ete mis a jour.
