Impact of Irradiation and Thermal Aging on DWPF Simulated Sludge Properties

摘要

The research and development programs in support of the Defense Waste Processing Facility (DWPF) and other high-level waste vitrification processes require the use of both nonradioactive waste simulants and actual waste samples. These waste simulants were designed to reproduce the chemical and, if possible, the physical properties of the actual high-level waste. This technical report documents a study on the impact of irradiating a Sludge Batch 3 (SB3) simulant on the physical properties of the sludge, additional tests on producing a SB3 simulant using crossflow filtration and on the impact of aging an SB3 simulant by additional thermal processing.
