"I’ve never seen a movie that’s set 200 years in the future and the planet is being powered by fission reactors—that’s nobody’s vision of the future," he said. "This is not a future technology. It’s an old technology, and it serves a useful purpose. But that purpose is running its course."Huh? Quite different tone than many nuclear advocates. Given what happened after Fukushima, it is not surprising.
Jaczko argued that more Fukushima-type accidents are inevitable if the world continues to rely on the current types of nuclear fission reactors, and he believes that society will not accept nuclear power on that condition. "For nuclear power plants to be considered safe, they should not produce accidents like this," he said. "By 'should not' I don’t mean that they have a low probability, but simply that they should not be able to produce accidents like this [at all]. That is what the public has said quite clearly. That is what we need as a new safety standard for nuclear power going forward." He acknowledged that new reactor designs such as small modular nuclear reactors and some Generation IV reactor designs could conceivably meet such a safety standard, but he didn't sound enthusiastic."[T]hey should not be able to produce accidents like this [at all]."? Not slightly remotely low probability? With that there is no way we can defend nuclear, or almost any other technology.
According to Wikipedia, he is no fan of nuclear before or during his stint at NRC. A strong prior.
