Abstract

La présente invention concerne un écarteur permettant de maintenir une distance entre un tube de force et un tube de cuve de réacteur dans un réacteur nucléaire et, de façon plus précise, un écarteur fixé en position entre le tube de force et le tube de cuve de réacteur. La position axiale de lécarteur est maintenue par le fait que lécarteur a un profil extérieur en contact étroit ou légèrement serré avec un profil localement élargi du tube de cuve de réacteur. Un écarteur, un tube de cuve de réacteur correspondant et un procédé dinstallation dudit écarteur sont décrits.
