Tank 41 Moveable Pump System Material Compatibility Report (U)

摘要

SRTC has designed a variable height pumping system for removal of low curie salt solution in High Level Waste (HLW) Tank 41. The harsh environment of Tank 41 can degrade many materials. The materials used in the Tank 41 Movable Pump System were chosen to provide a balance between schedule impact, cost, and resistance to degradation in service. In some cases materials were coated to increase their resistance to degradation, and in other cases replacement parts of more suitable materials were used. The materials used in the Tank 41 Moveable Pump system have a low chance of failure based on the material selected, the specific use for each material, and the four year design goal. This report documents the evaluation of the materials of construction for the service conditions.
