Pariseau, W. G.

Modification of the thermoelastic/plastic finite element program to account for large displacements possibly associated with the development of an extensive plastic zone about a radioactive waste container emplaced in a typical repository room (SALT-4/T model) has been completed. Comparisons of radial stresses acting on the waste container and borehole wall displacements computed by the modified and conventional analyses techniques reveal little difference between the two sets of results over a 10 year heating period for salt strengths 25 percent of original values. Because no significant differences in results arise even under these exaggerated conditions, the more costly large displacement option need be used only sparingly as an occasional control check on the conventional procedure. As a consequence, economy of computer run time can be maintained without sacrifice of accuracy.
