Mentioning Chernobyl at all, at least to me, shows a deep lack of understanding about nuclear power infrastructure and capabilities in the 21st century. It cannot be stressed enough that Chernobyl was a fluke on top of a fluke, with bad design and dangerous elemental choices at its core. It is nothing like the nuclear power tech we would choose to use today. Thorium MSR poses literally near-zero risk of meltdown, and the meltdown potential of Thorium can be compared to Chernobyl in parts per million.
Considering all of this, mentioning the threat of another Chernobyl every time nuclear power is positioned as a viable option is like thinking that the Valdez disaster occurs every time we ship gas overseas.
