Abstract

This paper will demonstrate the potential of modern design for additive manufacturing by using computational fluid dynamics with design optimization. The Transformational Challenge Reactor Instrumentation and Control (I&C) Team has specifically requested that an instrumentation plane be designed for monitoring of the core-coolant-flow average temperature within ±5°C of the core outlet average temperature. However, because of systemwide constraints, this design space is allotted a pressure drop of only 0.5 psi. A successful design optimization study is discussed along with the thought process leading to the successful conclusion of an I&C plane with an average temperature of 497.3°C and a standard deviation of 1.03°C, all while maintaining a 3.38-kPa (0.49-psi) pressure drop across the outlet plenum.
