Abstract
UN PROCESO DE AMORTIGUACION DE FASE BETA Y APARATO PARA TRATAMIENTO EN CALIENTE DE ENCAMISADO TUBULAR PARA COMBUSTIBLE NUCLEAR QUE EMPLEA LOS PASOS DE APLICAR CALOR A AL MENOS UNA PORCION DE LA SUPERFICIE EXTERIOR DEL REVESTIMIENTO PARA ELEVAR LA TEMPERATURA SOBRE EL NIVEL DE LA TRANSFORMACION DE LA FASE BETA MIENTRAS SUMINISTRA UN MEDIO DE REFRIGERACION QUE COMPRENDE UNA CANTIDAD CONTROLADA DE GOTITAS DE AGUA EN UN GAS FLUYENTE (TAL COMO NITROGENO) A UNA PORCION DE LA SUPERFICIE INTERIOR DEL REVESTIMIENTO PARA MANTENER LA SUPERFICIE INTERIOR A UNA TEMPERATURA POR DEBAJO DE UNA TEMPERATURA EN LA QUE SE PRODUCE OXIDACION O CRECIMIENTO DE GRANO INDESEADOS. DESPUES DE ESTO, LA PORCION CALENTADA DE LA SUPERFICIE EXTERNA ES AMORTIGUADA APLICANDO UN FLUIDO DE REFRIGERACION PARA REDUCIR LA TEMPERATURA RAPIDAMENTE A UN NIVEL PARA MANTENER LA ESTRUCTURA DE GRANO METALURGICO DESEADA QUE RESULTA DE LA TRANSICION DE FASE BETA.
