The Physics of Nuclear Power

Fissile: $_{92}^{235}U$ → 211.3 MeV → 86.75 TJ/kg. Crustal abundance 19.44 ppb. 4.83 MJ/liter.

Fertile: $_{92}^{238}U$ → $_{93}^{239}Pu$ → 211.5 MeV → 85.38 TJ/kg. Crustal abundance 2.7 ppm. 652 MJ/liter.

Fertile: $_{90}^{232}Th$ → $_{92}^{233}U$ → 200.1 MeV → 82.86 TJ/kg. Crustal abundance 12ppm. 2,813 MJ/liter.

Fusion: $_{3}^{6}Li$ + $_{1}^{2}H$ → $2\,_{2}^{4}He$ + 22.4 MeV → 270.2 TJ/kg. Crustal abundance 1.5 ppm. 1,150 MJ/liter.

$\sum _{m=1}^{\infty }\sum _{n=1}^{\infty }{\frac {m^{2}\,n}{3^{m}\left(m\,3^{n}+n\,3^{m}\right)}}$

An equivalent equation for the affine transformation is

$b'_{i}=b_{i}\oplus b_{(i+4)mod8}\oplus b_{(i+5)mod8}\oplus b_{(i+6)mod8}\oplus b_{(i+7)mod8}\oplus c_{i}$

where b' b and c are 8 bit arrays and c is 01100011.
