【 摘 要 】

The viscosity of a Hanford waste stream is potentially an indicator of its composition, including solids load, and of how well it has been mixed. Viscosity could be a useful control variable that might indicate the need for heating or dilution, for example. However, traditional off-line measurements are slow and samples can be difficult to take. Pausing processing to take samples disrupts and slows down production schedules and so, if viscosity measurements are necessary, requires increased capacity in the whole process. An alternative viscosity measurement that does not require sampling, and that is fast would be more useful than traditional techniques.
