Abstract
(EN)
A nuclear reactor vessel (1) has low alloy steel as its base material (11), and on the inside surface of the base material (11) are layered a plurality of build-up layers (22-24), which are formed by multilayer build-up welding with Inconel 690 alloy welding material, which is a Ni-base alloy based welding material. The build-up layer (22), out of the plurality of build-up layers (22-24), that is the initial layer layered directly onto the inside surface of the base material (11) is formed such that the Cr concentration does not exceed 16 mass% by build-up welding in which the dilution ratio is increased. High corrosion resistance can be obtained, and in post-weld heat treatment after the multilayer build-up welding, formation of a hardened layer at the weld boundary due to carbon in the base material diffusing to the welding material side can be suppressed.

L'invention concerne une cuve (1) de réacteur nucléaire ayant de l'acier faiblement allié comme matériau de base (11), et ayant, sur la surface intérieure du matériau de base (11), mises en couches, une pluralité de couches de rechargement (22-24), qui sont formées par une opération de soudage de rechargement à plusieurs couches au moyen d'un matériau de soudage de type alliage Inconel 690, qui est un matériau de soudage basé sur un alliage à base de Ni. La couche de rechargement (22), parmi la pluralité de couches de rechargement (22-24), qui est la couche initiale mise directement en couche sur la surface intérieure du matériau de base (11) est formée de telle sorte que la concentration de Cr ne dépasse pas 16 % en masse par le soudage de rechargement dans lequel le rapport de dilution est augmenté. Une haute résistance à la corrosion peut être obtenue, et dans le traitement thermique après soudage après le soudage de rechargement à plusieurs couches, la formation d'une couche durcie au niveau de la limite de soudure due à la présence de carbone dans le matériau de base se diffusant du côté matériau de soudage peut être supprimée.

 低合金鋼を母材11とする原子炉容器1であって、母材11の内面側には、Ni基合金系溶接材料であるインコネル690合金溶材で多層肉盛溶接して成る複数の肉盛層22~24が積層され、複数の肉盛層22~24のうちの母材11の内面側に直に積層される初層である肉盛層22は、希釈率を大きくした肉盛溶接によってCrの濃度が16mass%を超えないように形成されている。高い耐食性が得られ、多層肉盛溶接後における溶接後熱処理において、母材に含まれる炭素が溶接材料側に拡散して溶接境界部に硬化層が形成されるのを抑制することが可能である。
