Abstract

LA VASIJA DE UN REACTOR NUCLEAR QUE ESTA SUSPENDIDA DE LAS TOBERAS DE LA RAMA FRIA EN LA CAVIDAD DEL REACTOR ESTA PROVISTA DE UNA BARRERA TERMOAISLANTE INFERIOR SEPARADA DE LA VASIJA DEL REACTOR PARA FORMAR UNA CAMARA QUE PUEDE INUNDARSE DE AGUA REFRIGERANTE POR MEDIO DE VALVULAS PASIVAS PARA ENFRIAR DIRECTAMENTE LA VASIJA DEL REACTOR EN CASO DE ACCIDENTE GRAVE. LAS VALVULAS PASIVAS TAMBIEN INCLUYEN RESPIRADEROS BIESTABLES EN EL EXTREMO SUPERIOR DE LA BARRERA TERMOAISLANTE PARA LIBERAR VAPOR. UN ESCUDO DE NEUTRONES MODULAR Y DESMONTABLE QUE SE EXTIENDE EN TORNO AL EXTREMO SUPERIOR DE LA CAVIDAD DEL REACTOR BAJO LAS TOBERAS FORMA CON LA TRANSICION AHUSADA HACIA ARRIBA Y HACIA AFUERA EN LA SUPERFICIE EXTERIOR DE LA VASIJA DEL REACTOR UN CANAL DE LABERINTO QUE REDUCE LA FUGA DE NEUTRONES AL TIEMPO QUE ESTABLECE UNA VIA DE ESCAPE PARA EL VAPOR DURANTE UN ACCIDENTE GRAVE Y PARA EL AIRE REFRIGERANTE QUE SE HACE CIRCULAR A LO LARGO DE LAS PAREDES DE LA CAVIDAD DEL REACTOR FUERA DE LA BARRERA TERMOAISLANTE DURANTE EL SERVICIO NORMAL DEL REACTOR.
