Can hydrogen be the transportation fuel in an otherwise nuclear economy?
Let’s face it: The global economy should be powered primarily by nuclear power. And it probably will by the end of this century, with a still-significant assist from renewables and hydro. Once nuclear systems are dominant, the costs come down to where gas is now; and when carbon emissions are reduced to a small portion of their present state, it will become obvious that most other sources are only good in niche settings. I mean, why use small modular reactors to load-follow when they can just produce that power instead of buffering it?

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.
