"Global electricity consumption is on track to grow 45 percent by 2040, and the team’s analysis shows that the exclusion of nuclear from low-carbon scenarios could cause the average cost of electricity to escalate dramatically."
Yet, the reason why nuclear is dying in the Western world is cost. Which is actually admitted in
"The researchers find that changes in reactor construction are needed to usher in an era of safer, more cost-effective reactors, including proven construction management practices that can keep nuclear projects on time and on budget."
So we need to do to changes to arrive at something that's economical? But the nuclear industry has been trying to do this for years and failed.
Maybe it's just me, but I think a prudent conclusion is that fission is dying because it's really, really difficult to build something a team of engineers who are experts in the field consider safe enough to prevent disasters. Greenpeace et al. has no say in safety designs for reactors as far as I can tell, that's a red herring.
Some people think that serial production of smaller reactors are key. But then why didn't the industry have this epiphany many years ago? Instead they're building larger and larger plants. I remain sceptical.
