weapon shortly before its
mission. Fat Man was 12 feet
long, 5 feet in maximum
diameter, and weighed
10,300 lb when fully
assembled (Sublette 2007).

4.3 Predetonation Yield
Material in this section is adopted from Reed (2011).
In the previous section, it was explained how uncontrollable spontaneous fissions
inevitably lead to some probability that a nuclear weapon will suffer a predetonation.
