    The Phénix reactor shut down in 2009 so I think that was the end of France’s breeder reactors. India, China and Russia still have operating breeder reactors.

    Breeding from non-fissile material is different to reprocessing though. Reprocessing is a chemical process, not a nuclear one. The UK had an operational reprocessing capability - though it is being decommissioned now because it wasn’t cost effective with such a small fleet. Japan is still trying to bring its reprocessing plant online (after years of trouble). However France is doing it routinely for their domestic fleet and some foreign reactors IIRC. The USA made reprocessing illegal back in 1977 due to proliferation concerns. Despite that ban being repealed, they haven’t set up the regulatory infrastructure to be able to do it so no one has bothered. Maybe the new nuclear industry will shake that up a bit.

    They’re over by a factor of 6 which would add up to 21 hours, not 24. I don’t know what they’ve done to get 2.5 million, it should be 417 thousand with those numbers.

    Edit: Oh dear. They said each oven could completely cook 6 turkeys in a day so they rounded to that number. At least it no longer reads GW/day.

    1500 cubic meters

    Did you really pick the figure from the RBMK reactor type?

    For PWRs, 250 m³ of LILW per GW annum is 28.5 m³ of LILW per TWh.

    2.5 million turkeys in a 2.4 kW oven for 3.5 hours uses 0.021 TWh.

    So 2.5 million turkeys and 0.6 m³ total low and intermediate wastes generated. Most of this can be released after ~300 years with negligible activity over natural background. That is a long time but not “basically forever”.

    No permanent storage location for the waste has been found, to date.

    Onkalo

    to burn the unburned fuel you would have to breed the material

    France reprocesses spent fuel. With increased scale it would be cheaper and cut down on the volume of waste that must be dealt with regardless of if there’s a nuclear industry in the future.







  • Yeah the Rolling Stone article is written really weirdly. I don’t think it’s technically wrong anywhere but it reads really misleadingly when you compare it to the actual report.

    Like it leads with “the group identified the Tesla Model S and Tesla Model Y as two of the most dangerous cars” - meaning they are in the list - at sixth and twenty first places respectively. The mix is really weird though. As you mention the top of the list is cars like the Chevy Corvette and Porsche 911, but also things like the Mitsubishi Mirage and a load of Kia models. So it seems like there’s a lot to interpret there.

    Certainly it’s somewhat damning that despite the driver assistant technology, these models are not particularly safer. But I think other manufactures have a wide range of vehicles at different price points that also vary in safety, which brings their averages below Tesla’s in the final rankings.
