The theory of the multigroup energy approximation. The multigroup energy approximation in radiation transport assumes that [an] energy domain … is partitioned into … intervals of width … By convention the energy decreases with increasing group number. 1, record 1, English, - multigroup%20energy%20approximation

[…] les erreurs systématiques provenaient non seulement des incertitudes sur les données fondamentales de base (sections microscopiques) mais aussi des approximations méthodologiques. Parmi ces dernières, on peut citer la séparation espace-direction angulaire-énergie des neutrons dans les calculs spectraux, la non-utilisation systématique de modélisation tridimensionnelle et l’approximation énergétique multigroupe dans les études de projets industriels. Ces études sont relatives à des calculs de cœurs de réacteurs, des piscines de stockage d’assemblages usés, des calculs de protection et toutes autres études mettant en jeu des neutrons. 1, record 1, French, - approximation%20%C3%A9nerg%C3%A9tique%20multigroupe
