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.

SCK•CEN is at the forefront of Heavy Liquid Metal (HLM) nuclear technology worldwide with the development of the MYRRHA Accelerator Driven System. MYRRHA is a flexible fast-spectrum pool-type research reactor cooled by Lead Bismuth Eutectic and was identified as the European Technology Pilot Plant for the Lead-cooled Fast Reactor.
In this paper we will present selected topics from the R&D program on HLM thermal-hydraulics that are essential for the design, engineering and safety analysis of MYRRHA and other HLM-cooled reactors, including turbulent heat transfer in HLM, fuel assembly thermal hydraulics and flow-induced vibrations, control rod hydrodynamics, primary heat exchanger pool and integral system thermal hydraulics, sloshing and multi-physics modelling.
