The Pathfinder
Atomic Power Plant
built by Northern
States Power Company
near Sioux Falls
begins producing
electricity. It was
considered the
world's first
all-nuclear power
plant. After only
one year's
operation, however,
it was converted to
a conventional power
plant because of
technical problems.
