  1. 1. Applications of On-Line Continuous Solvent Extraction in Nuclear Chemistry

    Författare :Rikard Malmbeck; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; reactor water; Seaborgium; BWR; mixer-settlers; Dubnium; Bohrium; transactinides; centrifuges; speciation; SISAK; solvent extraction; Iodine; Rutherfordium;

    Sammanfattning : Methods and procedures for on-line continuous chemical separation of iodine species in reactor water and for transactinides in heavy element chemistry have been developed. Radioiodine is one of the more important fission products in terms of nuclear reactor safety due to its high fission yield, significant radiobiological hazard and potential volatility. LÄS MER
