The core of a nuclear reactor comprises a central fuel zone, in which a fissile material normally constituted by a [mix] of enriched uranium oxide and plutonium oxide. This fuel zone is completely surrounded by a covering of fertile material normally constituted by depleted uranium oxide. In practice, this structure is obtained by juxtaposing vertical assemblies having a hexagonal section.

Intérêt du caractère discontinu du ralentissement (autoprotection en énergie). Quand on remarque les valeurs gigantesques que peuvent atteindre les sections efficaces au voisinage des pics des résonances, on peut craindre que les neutrons soient absorbés bien avant d'avoir pu se ralentir; comme ces absorptions sont pour l’essentiel des captures sans fission par l’uranium 238, cette crainte semble mettre en péril le concept même de réacteur à neutrons thermiques. En réalité, cette crainte n’est pas réellement fondée du fait que les résonances sont très élevées, certes, mais également étroites. Les neutrons se ralentissent de façon discontinue par diffusions en «sautant» d’une énergie à la suivante sans passer par les énergies intermédiaires : très souvent, ils évitent ainsi les «trappes» – les étroits domaines d’énergie où la section efficace est grande et où ils risqueraient d’être absorbés –, sans «soupçonner» le danger auquel ils ont échappé. 1, record 11, French, - autoprotection%20en%20%C3%A9nergie

Par ailleurs, du matériau combustible mixte UO2-PuO2(MOX) est actuellement introduit dans certains réacteurs d'EDF [Électricité de France], afin de consommer une partie du plutonium formé lors des cycles précédents. Ces éléments combustibles nécessitent un contrôle de leur réactivité en début de vie plus efficace que celui des éléments UO2 classiques. En effet, ils génèrent un spectre neutronique «durci», c'est-à-dire déporté vers des énergies de neutrons plus élevées, d'où une perte d'efficacité des éléments absorbants classiques ce qui nécessite une augmentation du nombre de barres de commande dans le cas du MOX. 1, record 17, French, - spectre%20neutronique%20durci
