Abstract

Some test parameters have become issues in test development either because they are difficult to measure and control or because the significance of their effect on waste form dissolution and alteration is unknown. Issues identified by the MCC are Eh/pH system effects, SA/V effects, temperature effects on sampling, waste package composition effects, colloid formation and stability, radiolysis, and formation kinetics and stability of secondary reaction products. These issues are addressed by the MCC through literature reviews, workshops, and direct investigation with the objective of recommending methods for resolving them. This paper summarizes their status and attempts to identify needs required for their resolution.
