PROPERTIES IMPORTANT TO MIXING FOR WTP LARGE SCALE INTEGRATED TESTING

摘要: Large Scale Integrated Testing (LSIT) is being planned by Bechtel National, Inc. to address uncertainties in the full scale mixing performance of Hanford Waste Treatment and Immobilization Plant (WTP). will use simulated waste rather than actual waste. Therefore, suitable simulants critical achieving goals test program. External review boards have raised questions regarding overall representativeness used previous tests. Accordingly, WTP requested Savannah River National Laboratory (SRNL) assist with development for LSIT. Among first tasks assigned SRNL was develop a list properties that matter pulse-jet mixer (PJM) tanks. This report satisfies Commitment 5.2.3.1 Department Energy Implementation Plan Defense Nuclear Facilities Safety Board Recommendation 2010-2: physical important scaling. In support simulant development, following two objectives are focus this report: (1) Assess chemical testing scaling relationships; (2) Identify governing associated ranges LSIT achieve Newtonian non-Newtonian objectives. includes sampling heel management systems.
