Abstract

Un método para limpiar un ensamblaje de bomba de chorro de un reactor nuclear puede comprender insertar una herramienta de limpieza dentro del ensamblaje de la bomba de chorro de tal manera que una cara frontal de la herramienta de limpieza es adyacente a una superficie interna del ensamblaje de bomba de chorro y por debajo de un nivel de un primer líquido en el ensamblaje de la bomba de chorro; el método puede comprender adicionalmente dirigir una pluralidad de chorros frontales de un segundo líquido desde una pluralidad de orificios frontales sobre la cara frontal de la herramienta de limpieza de tal manera que la pluralidad de chorros frontales del segundo líquido golpea la superficie interna del ensamblaje de la bomba de chorro; el método además puede comprender mantener una distancia de reserva entre la cara frontal de la herramienta de limpieza y la superficie interna del ensamblaje de la bomba de chorro durante la limpieza del ensamblaje de la bomba de chorro.
