* Long-term storage plans tend to be pretty solid, but then people remotely near it get rallied to protest it.
* Any cases of that are management issues, not nuclear power generation issues.
* Making safe nuclear reactors is a well-understood challenge. Even if you do include all incidents that have happened with outdated, flawed reactors, going all the way back, nuclear reactors have cause far less environmental damage and far fewer deaths per power unit than fossil fuels do. Also, this article is about SMRs, which have very different requirements.
* Nuclear waste storage is a solved issue, this just repeats the first point.
• our past failures to get long-term storage of nuclear waste right
• the cost and time overruns for building nuclear plants in the last several decades
• the possible catastrophic failures even in a country like Japan
• the long term storage issue and its cost.
These serious unsolved issues are being hand-waved away again and again.
