摘要：In the 1950s, the high-level liquid waste (HLLW) was intended to be immobilized in the crystals of synthetic minerals. HLLW was calcinated in the fluid bed into dry powder in the Argonne laboratory of

摘要：During the process of bituminization, there has been more than 330 barrels waste accumulated. The flushing fluid containing TCE, water, asphalt etc. is radioactivity, causticity and toxicity and will be harmful to the environment in the long term storage.

摘要：As normal decontaminant acids and alkaline were used for decontamination of spent fuel reprocess-sing plant. But their efficiency is lower after repeating utilization due to the existing of hotspot (high doses spot). For fixed contaminants on the hotspots it is necessary to use more efficacious decontaminant.

摘要：The present research concerns in demonstration experiments in situ for dissolving behavior of the S-119 organic filth. The selected test conditions such as ambient temperature and atmosphere pressure, solvent AN1, solid to liquid ratio of 1:5 were adopted based on the experimental results in the laboratory. The sampling amount is about 100g S-119 organic filth.

摘要：In the high-level radioactive waste, some nuclides (237Np, 99Tc, 239Pu, 241Am, etc.) have the big toxicity and the long half-life, and these nuclides would destroy humanity survival environment if they

摘要：Humic acids strongly influence the chemical behaviour and migration behaviour of radionuclides due to its complexation and radox capacity under HLW deep-ground disposal conditions. The studies on interaction of humic acids with radionuclides require the isolation of humic acids from soil and the purification and characterization of obtained humic acids must be performed subsequently.

摘要：99Tc, a long-lived fission product, is one of the main components of high-level radioactive waste. Because of its toxicity and long-lived, it is always the research key point and occupies an important

摘要：An investigation of the source term of the spent radioactive resins was preformed in China Institute of Atomic Energy (CIAE). The intention of this task was to provide a reference or instruction for the

摘要：Same as the main preparation method for high purity of 123I in other countries, we would use also 99.9% of 124Xe gas via 124Xe(p,x) reaction and 123Xe decay to get the objective product 123I.

摘要：Apoptosis, also known as programmed cell death, is an indispensable component of normal human growth and development, immunoregulation and homeostasis. Apoptosis is nature’s primary
