Properties of cement-solidified radioactive waste forms with high levels of loading
- 1. Pennsylvania State University, University Park, PA
Description
Waste forms developed for nuclear defense waste were based on the concept of matrix encapsulation in cementitious host matrices. The physical properties of these waste forms were studied to evaluate the extent of waste loading that might be feasible and still maintain a leach-resistant, strong, monolithic object. The data indicate that, for a minimum compressive strength of 21 MPa, waste loadings of 40 to 60 wt% are possible. Leaching of selected samples with 30 and 70 wt% waste loading indicates that leach rates for Cs and Sr comparable to those found for glass and ceramic waste forms can be achieved in cementitious composite materials
