Abstract
Procedimiento y aparato para sujetar y remover barras de veneno combustible de la armadura de un conjunto combustible, cuya barra de veneno tiene un vástago que sobresale de uno de sus extremos, cuya armadura tiene un ánima para recibir el vástago, procedimiento caracterizado porque comprende las fases de insertar el vástago en dirección axial en el ánima de la armadura, soldar una parte del vástago a la armadura, ejercer presión en el vástago en dirección axial con respecto al ánima con fuerza suficiente para vencer la fuerza que sujeta el vástago en el ánima y retirar el vástago del ánima.
