Optimization for solidification of low-level-radio active resin using Taguchi analysis

Solidification of low-level-radioactive (LLW) resin was optimized using Tag uchi analytical methodology, The ingredients in LLW mortar which caused the solidification of cement were evaluated through consecutive measurements o f the effects of various concentrations of ingredients. Samples selected ac cording to Taguchi's method were separated into IS different categories and measured at the 7th, 21st, and 28th day after fabrication on developing ef fects. Evaluations of the various samples focused on whether the compressiv e and bending strength fulfilled the special criteria of the Taiwan Power C ompany (TPC). Similar results indicated that both furnace slag and fly ash were the dominant material resulting from the solidification of LLW mortar. The superior combination was obtained as furnace slag 24 wt. %, fly ash 24 wt. %, and cement 8 wt. % to mix 24 wt. % of resin with 20 wt.% of water, to fulfill the contemporary requirements of TPC.
