Title DWPF SMECT PVV Sample Characterization and Remediation.
Publication Date May 2013
Media Count 24p
Personal Author C. J. Bannochie C. L. Crawford
Abstract On April 2, 2013, a solid sample of material collected from the Defense Waste Processing Facility's Process Vessel Vent (PVV) jumper for the Slurry Mix Evaporator Condensate Tank (SMECT) was received at the Savannah River National Laboratory (SRNL). DWPF has experienced pressure spikes within the SMECT and other process vessels which have resulted in processing delays while a vacuum was re-established. Work on this sample was requested in a Technical Assistance Request (HLW-DWPFTAR- 2013-002). This document reports the results of chemical and physical property measurements made on the sample, as well as insights into the possible impact to the material using remediation methods proposed by DWPF. DWPF was interested in what the facility could expect when the material was exposed to either 8M nitric acid or 90% formic acid, the two materials they have the ability to flush through the PVV line in addition to process water once the line is capped off during a facility outage.
