LIQUID-METAL-COOLED FAST-NEUTRON REACTOR CORE HAVING A LOW DRAINING EFFECT

The invention relates to a liquid-metal-cooled fast-neutron reactor core having a low draining effect. The core comprises, from top to bottom, a neutron-absorbing upper zone (8), a liquid-metal plenum zone (10), an upper fertile zone (12), an intermediate fertile zone (14) and a lower fissile zone (...

Beschreibung
Zusammenfassung:	The invention relates to a liquid-metal-cooled fast-neutron reactor core having a low draining effect. The core comprises, from top to bottom, a neutron-absorbing upper zone (8), a liquid-metal plenum zone (10), an upper fertile zone (12), an intermediate fertile zone (14) and a lower fissile zone (16). The horizontal mid-plane (P1) of the intermediate fertile zone, of height HFE, lies beneath the horizontal mid-plane (P2) of the assembly formed by the lower and upper fissile zones and the intermediate fertile zone, the ratio of HFE to the height of this assembly varying from 0.25 to 0.40. Coeur de réacteur à neutrons rapides, refroidi par un métal liquide,à faible effet de vidange. Il comprend de haut en bas une zone neutrophage supérieure (8), une zone de plénum de métal liquide(10),une zone fissile supérieure(12), une zone fertile intermédiaire(14),une zone fissile inférieure(16);le plan médian horizontal(P1) de la zone fertile intermédiaire, de hauteur HFE, est situé au dessous du plan médian horizontal (P2) de l'ensemble formé par les zones fissiles inférieure et supérieure et la zone fertile intermédiaire;et le rapport de HFE à la hauteur de cet ensemble va de 0,25 à 0,40.
