In the frame of the safe disposal of nuclear waste, ONDRAF/NIRAS (Belgium) has submitted a license application for the exploitation of a near surface facility for the disposal of short-lived low and intermediate level waste. A significant part of waste intended to be disposed of in the surface repository is Pu-contaminated. The mobility of Pu through engineered barriers, like concrete or mortar, is highly affected by the sorption properties of these barriers surrounding the waste in the disposal facility. The presented case studies aim to quantify the sorption of Pu to an engineered barrier while coping with multiple uncertainties. The experimentation included a factorial screening study, followed by response surface studies, with further augmentation with replication and validation points.
