Nuclear explosives are, among other things, large-scale, low-cost
excavation devices. In this respect, with the proper pre-detonation
study and engineering, they are ideally suited for massive earth-moving
and “geological engineering” projects, including the construction of
harbors and canals. The western coasts of three continents, Australia,
Africa, and South America, are sparsely supplied with good harbors. A
number of studies have been undertaken as to the feasibility of using
nuclear explosives for digging deepwater harbors. Undoubtedly at some
time in the future, these projects will be carried out.
In addition, there are many places in the world where the construction
of a sea-level canal would provide shorter and safer routes for ocean
shipping, expedite trade and commerce, or open up barren and
unpopulated, but mineral-rich lands to settlers and profitable
development. The AEC Division of Peaceful Nuclear Explosives operates a
continuing program to develop engineering skills for such projects.[19]
Construction of a sea-level canal across the Central American isthmus is
one well-known proposal for this “Plowshare” program.
The use of nuclear explosives in this manner may one day change the very
shape of the world ocean.
