6. Conclusion

Andra has set a number of design requirements for the HA cell (storage container and liner). These provisions are designed to protect it from certain corrosion processes (stress corrosion, radiation corrosion) or to limit their effects. .

In addition, various design provisions are implemented to limit the presence of oxygen within the HA cell during the operating phase to ensure that the unalloyed steels (liner and storage container) remain in a protective or passivity range, leading to generalized corrosion rates of less than 10 µm.year...
