IEC 63186:2021 specifies the minimum requirements for the design of the seismic trip system, and the components thereof, used in a nuclear power plant to mitigate seismic effects. This system is intended to shut down the reactor in operation automatically before it is significantly impacted by the vibratory ground motion incurred by strong earthquakes. This document is applicable to both the design of new built plants and the upgrading of plants in operation. It may be used for the design of other types of nuclear facilities where normal operation shall be stopped in case of strong seismic motions. IEC 63186:2021 specifie les exigences minimales pour la conception du systeme de protection sismique et de ses composants, utilises dans une centrale nucleaire de puissance pour limiter les effets dun seisme. Le systeme est prevu pour arreter automatiquement le reacteur en fonctionnement avant quil ne soit endommage de maniere significative par le mouvement vibratoire du sol provoque par de forts seismes. Le present document est applicable a la conception de nouvelles centrales comme a la mise a niveau de centrales en exploitation. Il peut etre utilise pour la conception dautres types dinstallations nucleaires dont le fonctionnement normal doit etre interrompu en cas de mouvements sismiques importants.
