High Level Waste (HLW) Transfer Staging Alternatives Assessment

This document identifies potentially problematic transfers of high level waste (HLW) to the Waste Treatment Plant and assesses whether simple staging alternatives are available to resolve them. The problematic transfers are those transfers that could exceed allowable transfer-line operating pressures at the predicted critical velocity. If the actual waste properties for these transfers approach the bounding properties used in prior analysis, then there are no simple staging alternatives to resolve the problematic transfers. However, several alternatives were suggested that could work if it can be demonstrated that the actual median particle size is significantly less that the bounding value
