James Petigru, former SC Attorney

General• After South Carolina seceded in 1860,

Petigru famously remarked, "South

Carolina is too small for a republic and too

large for an insane asylum." This quote is

still used to describe contemporary South

Carolinian politics

• He died in

Charleston,

in 18632

Reprocessing - AGNS

• 1970 - Allied-General Nuclear

Services began constructing

commercial reprocessing plant at

Barnwell, SC

– Capable of 1500 tons/yr

– 400 acres

– ~$350M spent

• 1977 President Carter policy

change

• 1981 - Convinced that the project

could not proceed on a private

basis and that reprocessing was

commercially impracticable,

Allied halted the Barnwell project.
