The results obtained on glass in the NF-PRO project confirm the fundamental understanding of the dissolution mechanism also for very compacted near-field conditions in presence of material boundaries such as glass/iron corrosion product and glass/clay. NF-PRO has also reduced important uncertainties in the long-term performance of spent fuel under near- field conditions. A quantification of the remaining uncertainties in parameters and models is under way in the MICADO project. It has been shown that the instant release fractions (IRF) will not increase with time. Radiolysis effects were shown to be less important for fuel dissolution than previously thought. Although NF-PRO has improved our phenomenological understanding of the glass/SF dissolution processes, it is still difficult to reliably predict waste form performance under near-field constraints.",

N2 - For the first time, waste form behaviour (borosilicate glass and spent fuel) has been studied under near-field conditions in a fully integrated fashion. The results obtained on glass in the NF-PRO project confirm the fundamental understanding of the dissolution mechanism also for very compacted near-field conditions in presence of material boundaries such as glass/iron corrosion product and glass/clay. NF-PRO has also reduced important uncertainties in the long-term performance of spent fuel under near- field conditions. A quantification of the remaining uncertainties in parameters and models is under way in the MICADO project. It has been shown that the instant release fractions (IRF) will not increase with time. Radiolysis effects were shown to be less important for fuel dissolution than previously thought. Although NF-PRO has improved our phenomenological understanding of the glass/SF dissolution processes, it is still difficult to reliably predict waste form performance under near-field constraints.
