As a rule of thumb, If something seemed too good to be true, but then never was adopted at scale; assume that it didn't worked as planned in the real life, and was silently discarded to save face. Lost of trust in a mega-project is a serious issue.

To start, the sellers of the project will be pressed to embellish the history and real capabilities of the system.

And mega-projects are a magneto for corruption. Part of the money will vanish, then somebody will typically hide it, cutting corners in safety, and then some horrified official looks at it and thinks: "No way I will sign the green light and associate my name with this mess".

This is a dilemma. Politicians can't never, ever admit that this never worked (and millions were burnt by their naivety). "best thing since chocolate with grapes, but can't be opened and will never be" is a common defense. Plus <blame deflected to outer group like hippies or public> for better measure.

I'm not saying that this is the case here, but it just happens a lot with mega projects and, lets face it, companies working on nuclear projects were all except honest or transparent with the public on those years
