Title (EN) ASSEMBLY FOR A PRESSURISED WATER NUCLEAR REACTOR COMPRISING RODS WITH TWO GADOLINIUM CONCENTRATIONS
(FR) ASSEMBLAGE POUR REACTEUR NUCLEAIRE A EAU SOUS PRESSION COMPRENANT DES CRAYONS A DEUX TENEURS EN GADOLINIUM
Abstract: front page image
(EN)The invention relates to a fuel assembly (1) for a pressurised water nuclear reactor. The inventive assembly comprises first nuclear fuel rods (15) having a first mass concentration of gadolinium and second nuclear fuel rods (17) having a second mass concentration of gadolinium. According to the invention, the second concentration is greater than the first concentration and, in addition, the first mass concentration is strictly greater than 2 %.
(FR)Cet assemblage de combustible (1) pour réacteur nucléaire à eau sous pression comprend des premiers crayons (15) de combustible nucléaire ayant une première teneur massique en gadolinium et des deuxièmes crayons de combustible nucléaire (17) ayant une deuxième teneur massique en gadolinium. La deuxième teneur est supérieure à la première teneur. La première teneur massique est strictement supérieure à 2%.
