How much energy would it take to extract one ton of uranium from the ocean?

• Symmetry 6y ago
  Well, according to "Sustainable Energy Without the Hot Air" >Japanese researchers have found a technique for extracting uranium from seawater at a cost of $100–300 per kilogram of uranium, in comparison with a current cost of about $20/kg for uranium from ore. Because uranium contains so much more energy per ton than traditional fuels, this 5-fold or 15-fold increase in the cost of uranium would have little effect on the cost of nuclear power: nuclear power’s price is dominated by the cost of power-station construction and decommissioning, not by the cost of the fuel. Even a price of $300/kg would increase the cost of nuclear energy by only about 0.3 p per kWh. The expense of uranium extraction could be reduced by combining it with another use of seawater – for example, power-station cooling. https://www.withouthotair.com/c24/page_165.shtml https://www.withouthotair.com/c24/page_165.shtml https://www.withouthotair.com/c24/page_174.shtml https://www.withouthotair.com/c24/page_174.shtml

    Do you know if withouthotair is actively maintained? I used it in school more than a decade ago and I would love to reread a new version. I know the author died in 2016.

  This article estimates that the cost of seawater extraction would be roughly 10x the current market price, although not much word on the energy consumption. [0] https://sci-hub.tw/https://doi.org/10.1016/j.pnucene.2017.04.016 https://sci-hub.tw/https://doi.org/10.1016/j.pnucene.2017.04...
