I can't speak to the chemical plants near you but with nuclear power, you always have incredibly dirty radioactive materials inside a container, with lots of complex plumbing leading into it, and under worst case conditions that stuff can potentially always get into the air and water and get spread far and wide.
Although in principle we could make it never fail over the lifetime of human beings, in practice, we as a species, don't know how to do that, and the proliferative effects of nuclear power and their association with nuclear bombs cannot be underestimated either.
To make nuclear power completely safe, is like trying to make water not wet. It's built into the nature of what we are doing with the materials, for utility-scale nuclear power they are always on the edge of melting down.
Because of these inherent properties it's also never been cheap; the extensive containment and safety you need to engage in, seriously impairs the economics and what you have to do to get around that problem, renders it an inflexible source of power. You have to run it essentially flat out to get the kWh price down to reasonable figures. The most successful systems (like in France) have hydroelectricity or other additional flexible supplies to balance out the power. But if you have that anyway, then overall, technologies like wind power are now usually cheaper and incredibly less risky and easier to install, and compared to nuclear power which is a more mature technology, still getting significantly cheaper over time.
Throwing money at such inherently risky technology like nuclear power to try to make it less risky is not a wise investment right now, and all the signs are that it is only getting less wise with time, other technologies are rapidly rendering it moot.
