Development of a Liquid Jet Sludge Re-suspension Model (used on Pulse Jets or Jet Ballasts)

摘要

A performance prediction method has been developed for a radioactive or inactive liquid jet sludge re-suspension system and it has been applied to a jet ballast (or pulse jet) system in active nuclear waste tanks at Sellafield. British Nuclear Group has frequently used such systems, including the RPP-WTP Vitrification plant design at Hanford (Hannigan 2001). A model has been developed based on work by British Nuclear Group and previously published work at Savannah River, Hanford and others (See references). Originally, this was developed as a semi-empirical model in 2001. Later most of the semi-empirical factors have been replaced by theory and measurement based concepts, so that for simple re-suspension systems the model may possibly be generalised to apply to other jet re-suspension systems at least for relatively shallow sludge beds.
