The properties and the component of HLLW (High Level Liquid Waste) were studied.The genuine saline HLLW is a blue green liquid without any deposition.Its density and acidity are 1.399 g/ml(23±1 C) and 2.1 mol/L HNO 3, respectively. The activities of 137 Cs, 90 Sr, 99 Tc, 237 Np, 239 Pu, 241 Am,total α, total β, total γ are determined. The extractabilities of actinides in the genuine HLLW were examined with a five stage cross extraction experiment. More than 98% of Pu is in Pu 4+ species, and more than 70% of Np is in Np 4+ species. More than 99.97%α nuclides could be extracted by 30%TRPO Kerosene in 1 mol/L HNO 3 from the HLLW.
