With the reactor operating at a fixed power level, the system shall continually adjust the reactivity of the core in response to gradual changes of reactivity, primarily due to normal fuel burn-up. This control of reactivity may be considered as "fine" or "short term" reactivity control and is exercised by automatic operation of the available reactivity control devices. 2, record 1, English, - fine%20control

Lorsque le réacteur fonctionne à un niveau de puissance déterminé, le système de régulation doit continuellement régler la réactivité du cœur en fonction des variations graduelles de la réactivité dues surtout à la combustion normale du combustible. Ce type de réglage de la réactivité peut être réputé «fin» ou «à court terme» et est généralement exécuté par le fonctionnement automatique des dispositifs de réglage de la réactivité qui sont disponibles. 3, record 1, French, - r%C3%A9glage%20fin

Gas-cooled reactor systems. The high-temperature reactor(HTR) uses particle fuel able to withstand high temperatures, allowing for very high burn-up and graphite as a moderator. Helium is used as a coolant, allowing an output temperature of more than 850°C. 1, record 2, English, - particle%20fuel

[...] à la fin des années 1950, le concept de combustible à particules de taille millimétrique est le concept de référence des réacteurs à haute ou très haute température à caloporteur gaz (High or Very High Temperature gas cooled Reactor HTR/VHTR). La spécificité de ce combustible est qu'il est finement divisé, tout céramique (combustible et couches de revêtement) et micro-confiné (le confinement des actinides et des produits de fission se fait au plus près de la source), ces trois particularités combinées permettant à la fois l'accès aux hautes températures et à un haut niveau de sûreté. 1, record 2, French, - combustible%20%C3%A0%20particules

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. 3, record 3, French, - %C3%A9jection%20d%26rsquo%3Bune%20grappe%20de%20commande
