A review on the current status and production technology for 188W-188Re generator system

The current status of 188W-188Re generator production technology were reviewed in PART 1. Main interests were given to the aspects of 188W reactor production, irradiated targets reprocessing and generator loading technologies, such as alumina type and gel type generators. In order to develop the more convenient and advanced 188W-188Re generator, further studies must be carried out to get the precise evaluation of production and burn-up cross section of 188W, the more easily realizable generator loading procedure, and also to optimize the column and generator design to compensate the deterioration of generator performance because of parent radionuclide decay. By irradiation of 186W enriched sample, 188W-188Re generator production experiments were performed to evaluate the possibility of 188W-188Re generator production using HANARO, and PART 2 describes about the experiments. The experimental results shows the possibility of practical 188W-188Re generator production using of low-specific activity 188W produced in HANARO. (author). 79 refs., 4 tabs., 26 figs
