Nuclear-carrier disposal plans and practical facilities

Would France face a gap between a theoretical nuclear-carrier disposal plan and facilities able to carry it out?

The same distinction could apply: having a plan does not ensure that disposal facilities are ready in practice.

The answer treats nuclear-carrier disposal as a practical infrastructure question. Britain is said to have an advantage through Sellafield's nuclear-material facilities. The comparison with American facilities is expressly uncertain. A later follow-up repeats that a theoretical plan and an executable disposal programme are different things.
