| | | -- Note on radioactivity of blocks: |
| | | -- Source: <http://www.wise-uranium.org/rup.html> |
| | | -- The baseline radioactivity of an isotope is not especially |
| | | -- correlated with whether it's fissile (i.e., suitable as |
| | | -- reactor fuel). Natural uranium consists mainly of fissile |
| | | -- U-235 and non-fissile U-238, and both U-235 and U-238 are |
| | | -- significantly radioactive. U-235's massic activity is |
| | | -- about 80.0 MBq/kg, and U-238's is about 12.4 MBq/kg, which |
| | | -- superficially suggests that 3.5%-fissile uranium should have |
| | | -- only 1.19 times the activity of fully-depleted uranium. |
| | | -- But a third isotope affects the result hugely: U-234 has |
| | | -- massic activity of 231 GBq/kg. Natural uranium has massic |
| | | -- composition of 99.2837% U-238, 0.711% U-235, and 0.0053% U-234, |
| | | -- so its activity comes roughly 49% each from U-234 and U-238 |
| | | -- and only 2% from U-235. During enrichment via centrifuge, |
| | | -- the U-234 fraction is concentrated along with the U-235, with |
| | | -- the U-234:U-235 ratio remaining close to its original value. |
| | | -- (Actually the U-234 gets separated from U-238 slightly more |
| | | -- than the U-235 is, so the U-234:U-235 ratio is slightly |
| | | -- higher in enriched uranium.) A typical massic composition |
| | | -- for 3.5%-fissile uranium is 96.47116% U-238, 3.5% U-235, and |
| | | -- 0.02884% U-234. This gives 3.5%-fissile uranium about 6.55 |
| | | -- times the activity of fully-depleted uranium. The values we |
| | | -- compute here for the "radioactive" group value are based on |
| | | -- linear interpolation of activity along that scale, rooted at |
| | | -- a natural (0.7%-fissile) uranium block having the activity of |
| | | -- 9 uranium ore blocks (due to 9 ingots per block). The group |
| | | -- value is proportional to the square root of the activity, and |
| | | -- uranium ore has radioactive=1. This yields radioactive=1.0 |
| | | -- for a fully-depleted uranium block and radioactive=2.6 for |
| | | -- a 3.5%-fissile uranium block. |
