How is a thorium cycle more resistant to meltdown than a conventional uranium reactor? The thorium has to be converted to U-233 before it will fission. Then you have nearly the same situation as U-235 fission, including the problem of decay heat which causes most meltdowns.
Any nuclear station regardless of MW capacity is going to occupy many acres of real estate when you consider the support, security, containment and isolation facilities needed on site. Wind and solar is often installed on real estate that has little other usage value, such as deserts mountainsides, and water. They can be in remote areas since they need little human attention and are not a security risk.
