We have environmental protection laws and safety regulations that will prevent you from supporting nuclear waste without massive precautions. Now, I'll concede that there is value in separating polluting industries from business and residential areas. In general, I think a system like Japan has that's much coarser and centrally administered to prevent kicking away the latter by wealthy home owners would be friendly desirable. The US zoning system is so fundamentally broken and full of overreach that no zoning would be a massive improvement.
