DEF

[Séquence accidentelle du comportement des combustibles dans un réacteur se traduisant par une] augmentation brutale et temporaire de l’énergie libérée dans les crayons combustibles situés à proximité [d’une] grappe [de commande].

OBS

La Commission spécialisée de terminologie et de néologie de l'ingénierie nucléaire (CSTNIN) déconseille, dans la version 2007 du Vocabulaire de l'ingénierie nucléaire, l’emploi de «barre de contrôle». Or, «grappe de contrôle» suit le même modèle et n’est donc pas recommandable.
