摘要

To clarify various kinds of precipitates formation behavior in high level liquid waste (I-ILLW) from the nuclear fuel reprocessing process, undissolved materials generated in concentration step under vacuum evaporation and aging step at various temperatures and nitric acid concentrations using simulated HLLW solution were closely investigated. Three kinds of material, mixed crystalline salt of barium and strontium (Ba0.5, Sr0.5M/SUB> (NO3)2), phosphomolybdic acid (P2O5?24MoO3?7H2O), and zirconium molybdate (Zr (OH)2- Mo
