摘要： Means for laterally supporting a nuclear steam generator against the effect of seismic loadings or other shock loadings imparted by external or internal causes are disclosed. Support is provided by means of a stiffening structure incorporating a shock suppressor apparatus which operates through the lever arm of a mechanical linkage. The apparatus is designed to permit unrestrained lateral movements caused by thermal growth of the equipment, but undesired lateral loadings, such as those caused by earth tremors or equipment failure, automatically render the apparatus operative to support the steam generator against these loadings.
