I don't know if I can answer the question, but I'll try to address the issue.
The problem is that the capacities of the utilities and operators and insurance companies are not unlimited. Therefore, at some level, all countries provide backstops for third-party liability in some way. This is certainly the case in the European nuclear liability conventions, as well as in the U.S. There's no such thing as no liability. The backstops are provided because you couldn't get an insurance that had no liability limit on it.
