Over the past two years a number of programs have been initiated that have introduced several variables to the production scene which can significantly influence Hanford dissolver capacity. The more important of these are the utilization of recovered acid for dissolution, the development of I and E fuel elements, and the advent of direct-casting methods for fuel element fabrication (dingot metal). Evaluation of the relative status of dissolution capability with potential production requirements has as a result become somewhat more complex due to the increasing difficulty of weighing the effects of the various parameters involved. It is the purpose of this report to present most of the details, relevent to dissolver operation, that are necessary for capacity evaluation, and from which conclusions as to dissolver adequacy can be drawn with reasonable confidence.
