OK, I'm a reactor operator for a nuclear reactor and this report is talking about "beyond design basis" faults. Faults which were not taken account for within the safety case for the plant. Now, bear in mind that this area of the world is not susceptible to the kinds of earthquakes Japan is, and also the fact that tsunamis just cannot happen to most of France's plants because they're inland, would make the event that happened in Japan certainly beyond design basis.
Now, that's not to say that more safety cannot be added. Many of France's plants are relatively old and new ideas have been integrated into newer plants. All this report is talking about is that more things can be done to address big bang type stuff, stuff that's practicable and useful, like adding more generators and installing them onto roofs. Not prohibitively costly, and can be useful in most faults. There's always more things that can be done to all plants, it's a judge of whether it's practicable, economical and in all probabilities, worth it. If statistically, an event is not likely to happen for 10,000,000 years, are you really going to design it out?
This report isn't saying that France's plants are unsafe. The editor should be shot. In my opinion, Fukushima was a success. These plants were due to be taken out of service within a year, they were very very old, old design and old in age. Yet, even with a massive earth quake, and a beyond design basis fault that wasn't understood during their design phase, no-one died due to radiation and contamination is well controlled and understood. It's also worth noting that all the modern PWRs in Japan surrounding Fukushima all shut down properly with no issues.
