Sorry I was trying to discuss Japanese climate but my writing wasn’t best. As for the evidences, it’s hard to find a well compiled list but Fukushima did have a number of safety issues unaddressed for reasons other than budgetary causes.

Off-site center for disaster control built 5km(3mi) off site, effectively on-site, all backup generators being at basement levels, and recently discovered issue of emergency vent lines terminating inside the containment building comes to mind.
