How large is the amount of plutonium in there? I highly doubt that it has the claimed potential.
- krasin 8mo agoI found the specs for the fuel source: https://upload.wikimedia.org/wikipedia/en/e/e9/SNAP-19C_Mound_Data_Sheet.pdf https://upload.wikimedia.org/wikipedia/en/e/e9/SNAP-19C_Moun... The high-power unit had 300 grams of Pu-238 in 1965. Given its 87.7 years half-life, only 187g of Pu-238 remaining. It's very hard to do much damage with this amount of radioactive material.
- onion2k 8mo agoIt decays to uranium-234 though, which still isn't exactly nice. It'll be a long time before it's a block of inert lead.
- krasin 8mo agoU-234 is ~3000x less radioactive than Pu-238, so having ~120g of U-234 is negligible. I really fail to see a problem with these tiny amounts of non-brittle material embedded into a solid case. It's still very dangerous, but it's locally dangerous (meters away), not at the scale of whole countries.
- khuey 8mo agoAround three pounds, and something like 40% of it has already decayed away since this happened in the 60s.
