Abstract

UN COMPLEJO REACTOR (100) NUCLEAR INCLUYE TAPONES FUSIBLES (112) PARA EVITAR QUE UN POZO HUMEDO (120) PUEDA FLUIR DENTRO DE UN TANQUE SECO (106), INCLUYENDO EL RECIPIENTE DE REACCION (102). CUANDO SE CALIENTA EN EXCESO EL NUCLEO Y LA MEMBRANA FUNDIDA CAE AL PISO DEL TANQUE SECO, EL CALOR PROCEDENTE DE LA MEMBRANA FUNDE LOS TAPONES FUSIBLES Y EL AGUA ANEGA EL TANQUE SECO. EL AGUA IMPIDE UNA REACCION DEL HORMIGON DE LA MENBRANA, REDUCIENDO AL MINIMO EL AUMENTO DE PRESION DENTRO DEL TANQUE SECO Y TAMBIEN LAS PROBABILIDADES DE MATERIALES RADIOACTIVOS QUE PUEDAN LIBERARSE AL MEDIO AMBIENTE.
