Table 1 Impact of different redox buffering cases
Case | Rate of matrix dissolution | Initial release of radionuclides | Gradient within OP | Gradient over bentonite | Comment |
|---|---|---|---|---|---|
A | Low | Low | Low | Low | Depends on effective, fast buffering |
B | High | High | High | Low | |
C | High | High | Variable | Variable | |
D | High | High | Medium | High | Possible colloid formation at redox front |
