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.

A computational study of the thermodynamic and elastic properties of the tungsten-berylliuminterface structure and the behavior of a helium-vacancy pair near the tungsten/beryllium interface is carried out by first-principles calculations. Briefly, the following properties were calculated: (1) electronic properties of the tungsten/beryllium interface structure and (2) thermodynamic functions, Gibbs free energy, entropy, and enthalpy and anisotropies and isotropic (poly-crystalline) elastic moduli (bulk, torsion, Young’s moduli) of the tungsten/beryllium interface structure containing helium interstitial atoms or helium-vacancy pairs. The computational study was to provide a critical appraisal of the effect of helium interstitial atoms on the properties of the tungsten/beryllium interface structure. Calculated interface properties could be incorporated in an antiradiation damaging feature evaluation system to develop and test tungsten-based composites as plasma-facing materials.
