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.

Pressure Sensitive Paint (PSP) was investigated as a potential measurement technique for studying advanced heat exchanger designs. An experiment was setup to emulate a single rod in a helical coil steam generator (HCSG) being subjected to flow. Background, wind-off, and wind-on images were taken with a CCD camera while the PSP was under excitation light from a UV lamp. Instantaneous images were taken at 7 fps at Re 30,000. Analysis of the pressure field images found the average wind-off pressure to be 102.49 kPa and the average wind-on pressure to be 103.24 kPa. Such small changes in pressure can be verified with dynamic pressure transducer measurements also taken at the surface of the rod. The present study only discusses the results from the instantaneous pressure sensitive paint images captured from the experiment. Future work looks to make use of the sensitivity of pressure field measurements the PSP is capable of within a larger scale helical coil steam generator model.
