Abstract
DISPOSITIVO DE GUIAMENTO DO SISTEMA DE CONTENÇÃO E RESFRIAMENTO DO NÚCLEO DERRETIDO DO REATOR NUCLEAR. A invenção está relacionada a um dispositivo de guiamento para um sistema de contenção e resfriamento do núcleo derretido do reator nuclear na ocasião de graves acidentes além da base do projeto. O dispositivo de guiamento, que é instalado abaixo de um vaso do reator e repousa em uma viga de consola, compreende uma porção cilíndrica em uma porção cônica com uma abertura, as paredes de tais porções sendo revestidas com um material resistente ao calor e de baixo derretimento e sendo dividido em setores por nervuras de reforço dispostas radialmente em relação a abertura. Uma estrutura de reforço do dispositivo de guiamento consiste de um anel de reforço externo superior, um anel de reforço externo inferior, uma virola de reforço interna, uma virola de reforço externa superior, uma virola de reforço média dividida em setores por nervuras de reforço, e uma virola de reforço externa inferior, bem como nervuras de apoio, uma base, uma placa inclinada superior que une o fundo cônico, as nervuras de reforço e a virola de reforço média, e uma placa inclinada inferior que une o fundo cônico, as nervuras de reforço e a virola de reforço superior externa. O resultado técnico consiste na contenção e resfriamento mais eficaz do núcleo derretido do reator nuclear.
