I read it 14 years ago or so, after the Fukushima accident. I don't think the science has changed since then, or since the 90s when this project was shut down. There continue to be so much money in coal, gas, and oil and it's from there I think most of the opposition to nuclear stems from.
Apart from fast reactors, there's also the traditional reactors and storage of spent fuel. Finland's close to opening their process facility: https://en.wikipedia.org/wiki/Onkalo_spent_nuclear_fuel_repo...
