Concentrated porcine serum with ultrafiltration 30KDa was purified with DEAF-Sephacel column chromatography. Buffer solution with pH 7 to 9 and buffer concentration with 0.01M to 0.05M, and NaCl gradient with 0M∼0.5M, 0M∼0.8M and 0M∼1.0M were used respectively for chromatographic purification. Optimal conditions were at pH 8.0, buffer conc. 0.03M and salt conc, 0M∼0.5M with immunoprotein concentration 82% and production yield 43%. Purified immunoprotein was identified in the molecular weight 50KDa and 15KDa by electrophoresis.

A conversion technology of long-lived radioactive nuclides is to separate the elements involved in spent fuel and convert them into physical and chemical type suited to fuel for transmutation. This study has been investigated the experiments tar fluorination-dissolution of Zr , UO₂, and CeO₂. These compounds are components involved in spent fuel and especially, Zr is the cladding material of fuel. The fraction of fluorination-dissolution was increased linearly with time. Zr and UO₂ were converted respectively 24.2,5.2% after 3hours. CeO₂ was converted into fluoride only 0,19%. This is considered to be due to the solubility of H₂ in the LiF-BeF₂ molten salt. Because hydrogen is used to reduce CeO₂ to CeF₃ but the solubility of H₂ is very low in the molten salt.
