The edge case was predicted, but market and political forces chose to ignore it. The GE Type II reactor had known issues. [0]
I should add that I am not strictly anti-nuclear, and it is super interesting that some of the largest funders of anti-nuclear propaganda have been actors from the fossil fuel industry. [1]

One of the major reasons thats we have a climate crisis is that we knee capped Nuclear in the 80s and prevent new reactors and new technology development for 40 years. That left the only providers able to fill the gap were fossil based (oil, coal and gas) - which pumped out significant CO2.
Not surprised at all that oil and gas is still trying to protect themselves from competition.
