And none of those had to do with the age of the plant.
Additionally, probabilistic risk assessment (which is what generates the number 1 accident in X years) is a model, and a tool, used to determine what is the most safety significant components which you need to maintain. A tool, nothing more. People cite numbers believing that they are gospel truth that a plant will only have 1 accident every X years, but it is only a tool.
Additionally, PRA depends on your design basis being correct from the start. PRA does not model operator error very well as what happened in TMI (multiple operator errors combined with process errors, multiple latent failures, etc), and does not model bad designs like chernobyl. PRA also can't account for an incorrect design basis, like only 14ft tsunami vs. 45ft.
tl;dr, age of the equipment and strucutres has had nothing to do with any nuclear accident. Only human error at some level of the process (design, operation, etc).
