Lieutenant Keith Main

Lieutenant Keith Main, a nuclear power engineer, serves as lead engineer for advanced motor technology at the Naval Nuclear Propulsion Program Headquarters in Washington, DC.

With both a Bachelors and Masters degree in Electrical Engineering, Main provides technical and program direction, coordinating over 25 scientists at facilities that include Naval Nuclear Propulsion Program contractors and laboratories, Naval research facilities, and shipyards, in programs valued at over $10 million annually. For the past two years, Main has directed the reactor coolant pump hydraulic development for nuclear-powered submarines. He also directs several advanced development programs, including a state-of-the-art thruster for submarines, and an effort to increase the torque density, and thus reduce the size and weight, of large-scale permanent magnet motors.

Lieutenant Jeremy S. Bowen

Lieutenant Jeremy S. Bowen, U.S. Navy Quality Assurance Officer aboard the USS SCRANTON, ensures all work meets stringent requirements for quality and for safety.

A graduate of the United States Naval Academy with a degree in Systems Engineering, Bowen has served as electrical assistant, reactor controls assistant, main propulsion assistant, and now as quality assurance officer. He has utilized his theoretical knowledge in both mechanical and electrical systems applying them to the practical workings of a complex nuclear propulsion plant. Bowen’s performance resulted in early promotion to assistant engineer. In this role, he coordinated all the maintenance and training for a 170-man crew. He led 30 watchstanders through many complex procedures, and his technical recommendations led to outstanding performance by the ship. Bowen has been handpicked to lead a group of 25 instructors at one of the Navy’s two nuclear training facilities.

John Beausang

John Beausang is an engineer who entered the Advanced Concepts group at Lockheed Martin’s Knolls Atomic Power Laboratory (KAPL) in Schenectady, New York, while studying for a masters degree in physics.

At KAPL Beausang quickly distinguished himself as an authority on the thermodynamic limits of thermophotovoltaic (TPV) devices, replacing a major void in the group after the departure of a senior scientist and the subsequent loss of modeling skills in the group. Beausang developed a MATHCAD model that determined the thermodynamic limit of a perfect TPV device. This model provided valuable insights into diode performance, providing a clear vision of optimal TPV diode architecture. His work is driving the research and development of potential TPV applications for Naval ships. He authored a paper and presented his work to an international audience at the 5th Conference on TPV Technology. He has also mentored a new employee on the fundamental understanding of TPV physics and has worked with his peers to develop the path ahead to achieve high TPV efficiency.
