Abstract
Perfeccionamientos en aparatos de medición para la fuerza elástica de rejillas distanciadoras para elementos combustibles de reactor nuclear, que presionan a la barra combustible circundada en cada caso por la malla del distanciador, contra por los menos dos botones de distanciador rígidos situados enfrente, caracterizados porque consta de un mandril dinamométrico que presenta el mismo diámetro que las barras combustibles a fijar mediante la rejilla distanciadora y contiene un brazo de flexión cuyo extremo libre está en contacto con el botón de distanciador elástico a medir, y cuyo otro extremo unido firmemente con el mandril está dotado de por lo menos una banda extrensométrica.
