I'd say that nuclear reactor design is an engineering disaster as it is now. There are too many chances that something bad happens. Why is it so? In the "2nd generation" they just took reactors used for nuclear marine propulsion, adapted to electrical energy production. That would have been fine if nuclear propulsion was not something military, but alas it was and so security was not the first goal of design. The choice of fuel (enriched uranium) was the first error.
