ERWs were two-stage thermonuclears with all non-essential uranium removed to minimize fission yield.
2.
This probably corresponds with the maximum pure-fission yield of the " Mod 0 ".
3.
The tritium, the fusion yield, the neutrons, and the fission yield were all increased accordingly.
4.
Pappas Dr . Philos degree on the thesis " A Radiochemical Study of Fission Yields ".
5.
The deuterium-tritium fusion in the boost gas at the center; the fast neutrons from fusion then ensure a full fission yield.
6.
All boosted fission weapons use tritium, which decays with time, reducing the designed fission yield by approx 4.4 % per year.
7.
These fission yields were calculated for 235 U assuming thermal neutrons ( 0.0253 eV ) using data from the chart of the nuclides.
8.
Many more neutrons per unit of energy are released in a thermonuclear explosion in comparison with a purely fission yield influencing the fission products composition.
9.
The same source suggests that the fission yield was 5 & middot; 10 18 fissions which would deliver 156 MJ of heat into the reactor.
10.
Reduction in the fission yield of a primary will reduce the thermonuclear nuclear yield by a similar proportion, or even lead to the thermonuclear fusion stage failing to ignite.
