Nuclear Dirigo
On April 22, 1959, Rear Admiral George J. King, superintendent of the Maine Maritime Academy, announced that following the completion of the 1960 training cruise, cadets would begin the study of nuclear engineering. Courses at that time included radiation physics, reactor control and instrumentation, reactor theory and engineering, thermodynamics, shielding, core design, reactor maintenance, and nuclear aspects.

The study of heavy elements produced in underground thermonuclear explosions requires the separation of trace quantities of actinide elements from several hundred to several thousand grams of fused rock containing the products from about 1017 fissions. After the sample is pulverized and dissolved in HNO3, HClO4, and HF, fluoride insoluble salts are precipitated. These are redissolved, and the actinides and lanthanides are extracted into tributyl phosphate from a solution that is highly salted with Al(NO3)3. The actinides and lanthanides are back-extracted intc water and then extracted into di-2-ethylhexyl phosphoric acid. Recovery from di-2-ethylhexyl phosphoric acid is achieved by esterification with decanol. The actinides are separated from the lanthanides by elution from a cation-exchange resin column with an ethanol-hydrochloric acid solution. Individual actinides are separated by elution from a cation-exchange resin column with α-hydroxyisobutyric acid.
