December 2013

Catholic University of America Vitreous State Laboratory Tour and Discussion of Experiments Conducted in Support of Hanford Site Waste Treatment and Immobilization Plant Select Systems Design [HIAR-VSL-2013-11-18]

This Independent Activity Report documents an oversight activity conducted by the Office of Health, Safety and Security’s (HSS) Office of Safety and Emergency Management Evaluations on November 18, 2013, at the Catholic University of America Vitreous State Laboratory (VSL).  Bechtel National, Inc. (BNI) is the contractor responsible for the design and construction of the Hanford Site Waste Treatment and Immobilization Plant (WTP) for the U.S. Department of Energy Office of River Production.  This HSS activity is part of a multi-phase review that focuses on the technical adequacy of the low activity waste (LAW) documented safety analysis and supporting basis.  BNI uses the VSL experimental data and reports to develop and issue calculations that model LAW melter and off-gas processing system performance.
