Abstract

L'invention concerne un combustible nucléaire destiné à être utilisé dans des réacteurs nucléaires refroidis à l'eau. Le combustible, qui est constitué d'au moins 80 % de nitrure d'uranium, possède une densité d'actinide supérieure à 9,7 g/cm3 et une porosité ouverte inférieure à 0,1 %. Par conséquent, le carburant est résistant à des attaques provoquées par l'eau et la vapeur et peut être utilisé à des températures supérieures à 250 degrés Centigrade.
