Abstract

UN SISTEMA NUCLEAR DE ESTE TIPO QUE INCLUYE UN CONTENEDOR (14) DONDE ESTA SITUADO UN RECIPIENTE DE PRESION DEL REACTOR NUCLEAR (12), TIENE UNA ALBERCA DE CONTENCION (22) HACIA LA CUAL PODRA DESCARGARSE EL VAPOR (20, 28) DE FORMA QUE PODRA CONDENSAR Y REDUCIR LA PRESION EN EL RECIPIENTE DE PRESION EN CASO DE QUE SE PRODUZCA UN ACCIDENTE TAL COMO LA PERDIDA DE REFRIGERACION DEL REACTOR O UN FALLO EN LA TUBERIA DEL VAPOR. EL VAPOR TAMBIEN PODRA DESCARGARSE (32) DIRECTAMENTE AL ESPACIO DEL CONTENEDOR PARA REDUCIR POSTERIORMENTE LA PRESION EN EL REACTOR. CUANDO SE REDUCE LA PRESION DEL REACTOR HASTA UN CIERTO VALOR, UN SUMINISTRO DE AGUA POR GRAVEDAD DESDE UNA ALBERCA DE AGUA ELEVADA (36) TENDRA LA SUFICIENTE CAPACIDAD PARA FLUIR EN CONTRA DE LA PRESION DEL REACTOR Y DENTRO DEL REACTOR PARA SUMERGIR LAS VARILLAS DEL COMBUSTIBLE EN EL MISMO . UNO O MAS CONDENSADORES DE AISLAMIENTO (40) ESTAN SUMERGIDOS EN UNA GRAN ALBERCA DE AGUA (50), ESTA SE ENCUENTRA ELEVADA A CIERTA DISTANCIA POR ENCIMA DEL RECIPIENTE DE PRESION. AL MENOS UNO DE LOS CONDENSADORES DE AISLAMIENTO ESTA PROVISTO DE UNA ENTRADA COMUNICADA CON UN CONDUCTO DE ENTRADA ABIERTO (42) DISPUESTO EN EL CONTENEDOR. EL VAPOR SITUADO EN EL ESPACIO DEL CONTENEDOR PODRA ENTRAR EN EL CONDENSADOR DE AISLAMIENTO PARA ENFRIARSE, EN CUALQUIER MOMENTO EN QUE OCURRA UN ACCIDENTE Y EL VAPOR SE DESCARGUE DENTRO DEL CONTENEDOR. LA CONDENSACION DEL VAPOR EN EL CONDENSADOR HACE HERVIR EL AGUA DE LA GRAN ALBERCA PERO YA QUE ESTA ESTA ABIERTA (52) A LA ATMOSFERA, LA CONDENSACION DEL AGUA HERVIDA SE DESCARGA HACIA EL EXTERIOR. LA CONDENSACION QUE RESULTA DEL ENFRIAMIENTO QUE SE EFECTUA EN EL CONDENSADOR DE AISLAMIENTO REGRESA (46) A LA ALBERCA DE CONTENCION Y LOS GASES NO CONDENSABLES QUE ESTAN PRESENTES EN EL VAPOR QUE ESTA SIENDO CONDENSADO SE SEPARAN (60) DEL CONDENSADOR Y SE DESCARGAN (62) EN LA ALBERCA DE CONTENCION.
