Neutronic spectral hardening of the Harmonie reactor: calculations and experiences
Description
Spectral hardening, i.e. the increase of the spectrum average energy of neutrons produced by Cadarache CEA Harmonie reactor, has been calculated and experimentally tested by the mean of a polyethylene shell surrounding the core. Results show that a 8cm polyethylene layer is enough to produce a spectrum with a hardness similar to that of a fission nuclear weapon. In these conditions, the reactor may be considered as well as a good simulator of the neutronic spectrum of the weapon

Le durcissement, c'est-a-dire l'augmentation de l'energie moyenne du spectre energetique des neutrons produits par le reacteur Harmonie du CEN Cadarache, a ete calcule et realise experimentalement a l'aide d'un manteau de polyethylene entourant le coeur. Les resultats montrent que 8 cm de polyethylene sont suffisants pour obtenir un spectre de durete comparable a celui d'une arme a fission. Dans ces conditions le reacteur peut etre considere comme un simulateur acceptable du spectre neutronique de l'armeFiles
