Conclusions The data cited imply a high structural and dimensional stability on the part of plate type fuel elements used in the SM-2 reactor. The linearity of the volume increase with burnup allows us to assess changes in the physical, hydraulic, and heat-transfer parameters of the core. We note that a process of layer separation resulting in a loss of pressuretightness sets-in in some fuel elements with 30% uranium burnup, and this could be involved in failures during cooling or cooldown. Checking out this last point would enable us to settle on a criterion for the limiting allowable burnup. It is highly probable that this criterion will be related to the physics of the reactor, rather than to the degree of radiation damage of the reactor materials.
