Eternity Universe Alternate History

In the Eternity universe/Reality, Atomic bombs weren't detonated until
the 30th century. How would the lack of nuclear weapons have affected
the history of the 20th century?

However, there were nuclear power plants by the 24th century. They were
used to power the first Temporal Field generators. It took over a
century to extend a thin Temporal Field far enough uptime to tap the
energy of Nova Sol. This energy made it possible to make the field
large enough to hold a man, and eventually create Eternity. How was it
that there was nuclear power by the 24th century, yet no nuclear weapons
until the 30th century?
