Abstract

Una abrazadera de junta deslizante de tres puntos de una bomba de chorro de un reactor de agua en ebullición y procedimiento para su instalación, para atenuar el flujo de fugas de la junta deslizante inducido por vibraciones del conjunto de bomba de chorro de un reactor de agua en ebullición (8). Un collar (12a/12b) es instalado sobre la corona superior (2a) de un difusor (2). El collar, incluye un conjunto de sujetadores inferiores (14) y un conjunto de sujetadores superiores (16) que contactan con el mezclador de entrada (4) y con el difusor (2), respectivamente, para estabilizar horizontalmente el mezclador de entrada (4) en una posición fija dentro del difusor (2). Los sujetadores superiores (16) pueden ser anclados por realces (18) que aseguran un diseño de peso ligero del collar. Una junta en voladizo opcional puede atenuar fugas de la interfaz de la junta deslizante.
