Nuclear Reactor Thermal Hydraulics

In nuclear engineering and radiation science at S&T, the emphasis is on multiphase flow phenomena for light-water reactor safety. Nuclear reactor thermal hydraulics comprises areas of thermodynamics, fluid mechanics, and heat transfer of interest in the safety and operation of nuclear reactor systems. With the advent of passive safety systems and the increasing popularity of small modular reactor and advanced reactor designs, new approaches for heat transfer and reactor safety systems must be developed and tested.
