Abstract

Procedimiento para el ensayo de fugas en elementos de combustible de reactores nucleares, rellenos de helio, caracterizado por comprender las etapas de hacer que el helio penetre en la envoltura del elemento de combustible, por inmersión de este en helio; de cerrar la envoltura y trasladar el elemento de combustible a una cámara llena de un gas distinto del helio, a una presión tal que si existe una fuga en la envoltura del elemento de combustible, el helio puede difundirse desde la envoltura del elemento de combustible, a través de la salida, al interior de la cámara, sin desabsorción de helio desde la superficie de la envoltura del elemento de combustible y, finalmente, de ensayar el gas de la cámara en cuanto al contenido de helio, sin reducir la presión de gas en la cámara, por debajo de la presión a que el helio se desabsorbe de la superficie de la envoltura del elemento de combustible.
