Vogtle Unit 4 is the newest nuclear reactor in the United States, achieving commercial operation on April 29, 2024, in Georgia. It is the second of two new AP1000 reactors (Units 3 and 4) built at Plant Vogtle, following Unit 3 which began service in July 2023. Together, they represent the first newly constructed US nuclear units in over 30 years.
Everything was wrong with the design, from the control rods to the safety systems and overrides.
Three Mile Island, which happened 6 years prior and even before Chernobyl unit 4 was first brought on line, would have automatically SCRAMed itself in the conditions that the operators of unit 4 put their reactor in. And infact, TMI did SCRAM itself to prevent runaway reactions when it had it’s accident, but a faulty indicators prevented operators from being aware a relief valve was locked open.
All of the other RBMK designs were retrofitted in the final years of the USSR and following it’s collapse to rectify some of the design problems, but Russia is the only country that still operates the design. Ukraine and Lithuania decommissioned theirs by 2009.
Compared to Western, modern designs Chernobyl wasn’t regulated. That’s kind of the reason it became such a catastrophe.
When was the last time the US built a reactor successfully?
Been building A1B rectors regularly and on time for a decade now. But to answer your question, this year.

A1B isn’t civilian.
Get better at research.
It was regulated, but for a test they ignored the regulations knowingly.
Its Russia. It was “regulated”.
This is critical, it blew up during an unsanctioned test in which the director ordered safety protocols ignored.
Nothing wrong with the design, the other three reactors have been working since then.
