moderation ratio

sciences naturelles et appliquées - iate.europa.eu

▷

Optimized transition from the reactors of second and third generations to the thorium molten salt reactor... We developed parametric studies to optimize these TMSRs, amongst which the study presented here, based on one of the main TMSR parameters: the percentage of heavy nuclei in the fuel salt of the TMSR configuration, which modifies the moderation ratio of the reactor and thus influences both the initial fissile inventory and the spectrum of the reactor....

Neutronics of a liquid salt cooled- very high temperature reactor... The results show that the total void worth coefficient can be set negative provided that the fuel to moderator ratio is optimized and the moderating ratio of the coolant is sufficiently large; whereas the fuel and moderator temperature reactivity coefficients are negative at any fuel to moderator ratio
