Abstract

1. Procedimiento para la fabricación de un cerramiento de núcleo soldado que encierra a los elementos combustibles de un reactor de agua a presión, con varios anillos de costillas perfilados paralelas, que están dispuestas horizontalmente y presentan escotes con un contorno poligonal correspondiente al núcleo del reactor, y con chapas de cerramiento fijadas verticalmente a los anillos de costillas perfilados y que forman una envuelta adaptada al contorno del escote, caracterizado porque se fijan mediante soldadura sobre los anillos de costillas perfilados en un lado, unas costillas con una altura correspondiente a la separación de los anillos de costillas perfilados; los anillos de costillas perfilados se van soldando sucesivamente uno tras otro formando una jaula; las chapas de cerramiento dobladas parcialmente formando una jaula; las chapas de cerramiento dobladas parcialmente formando perfiles se van montando formando la envuelta, apretándolas contra la jaula, las chapas de cerramiento se van soldando preferentemente partiendo del centro, sucesivamente con los anillos de costillas perfilados de la jaula y; las chapas de cerramiento se sueldan entre sí formando una envuelta estanca.
