> I highly doubt it but I'd love to see the math on that. It was very rough hyperbole/fermi estimate. Can't find figures for the US, so using europe. Europe has 2.5 million m^3 of low level waste and 1.5 million m^3 that's fairly imminent from refurbishments/decommisioning and replacement (an array of 6 by 6 football fields stacked 20 yards). This is only about ~50 years, so it will go up over time. Europe uses about 2660TWh/yr or 300GW At 500Wh/L (high but existing) that's 4 hours for the 2.5. At 300Wh/L it's 4 hours at 4 million m^3 A lot of that waste probably doesn't need containment after a decade or two, so it's only a ballpark. (and a real battery can't be that densely packed without overheating). Conversely 5% or so of it needs multiple centuries or millenia so it would accumulate much higher. |
