Abstract
An apparatus and method for stabilizing a spent nuclear fuel containment cask so as to prevent tipping under design basis earthquake conditions. In one aspect, the apparatus comprises a lamina and a slid plate in surface contact with the lamina, forming a slidable interface; wherein the slidable interface has a coefficient of friction within a range resulting in an acceptable level of net horizontal displacement of a cask resting on the apparatus under design basis earthquake conditions.
