As much as we find them intriguing and wish for more of these advanced nuclear reactors, I find them to be extremely dangerous and hazardous if not taken proper care. The implications of the current nuclear power plants are critical enough for the residents living nearby. If we had to have more nuclear reactors, mini or advanced, what would be the global impact of having them at every other place? We do not want another Chernobyl incident to happen.
Nuclear power is indeed a step towards clean energy but it is not completely renewable due to the materials used. So instead of widespread installation of reactors across globe, we should find alternatives to expanding the existing set ups or finding remote areas where electricity is a dream and set up there to avoid human interaction as much as possible. Keeping in mind that the CO2 emissions caused by this is no less than that of a wind so nuclear is a great alternative. Additionally, we can have large scale deployments too.
