Monoamide compounds are porposed as complete incinereable extractants for aqueous reprocessing of nuclear spent fuel. The performance of the reprocessing processes where N,N-di-(2-ethyl)hexyl-butanamide is used as extractant is evaluated based on concentration profiles of U and Pu calculated with the consideration of acid and element concentration effects on the distribution ratios of U and Pu.

Separation of heat-producing fission products, i.e. Cs and Sr, will contribute to reasonable disposal of high level waste, because the wastes produces less heat. The separated Cs or Sr can be utilized as radiation source (Cs) or heat source (Sr). In the research on partitioning process, separation technology of Cs and Sr with inorganic adsorbents (zeolite, titanic acid) was developed. To enhance the applicability of this technology, it is important to develop a new adsorbent, which can separate Cs and Sr from highly acidic solution, i.e. several mol/L of nitric acid. Here, the results of literature survey on adsorbents of Sr are reported. Most of the literatures, which reported adsorptive distribution coefficients of Sr in nitric acid with HNO
concentration of 1 mol/L or more, were about antimonic acid compounds. The highest adsorptive distribution coefficient was reported in the literature of pure antimonic acid.. If a compound is consisted of Sb and an additional metal element, the reported adsorptive distribution coefficient of the compound seems to decrease. The selectivity of Sr against Eu seems to increase, if the nitric acid concentration increases.

The following items were studied for developing innovative equipment for analysis that provides high-sensitivity and rapid analysis for ultra small amount of samples utilizing microchip and thermal lens detector: Optimum flow condition for forming two-phase steady laminar flow in micro channel, applicability of thermal lens detector for U(VI) and H
concentration analysis, extraction properties of U(VI) from aqueous phase to organic phase in micro channel, and radiation resistance of microchips and capillary tubes. In this presentation the summary of these items are reported.
