Securing the advanced reactor fleet
Physical protection accounts for a significant portion of a nuclear power plant’s operational costs. As the U.S. moves toward smaller and safer advanced reactors, similar protection strategies could prove cost prohibitive. For tomorrow’s small modular reactors and microreactors, security costs must remain appropriate to the size of the reactor for economical operation.

Nuclear energy has been considered an important part of the long-term energy mixture in China. Accompanying the development of the nuclear power program, extensive research and development (R&D) activities were initiated. Nuclear thermal hydraulics has been recognized as a key subject in the development of nuclear technology because the target of nuclear thermal hydraulics is to remove heat safely from the fuel. The thermal hydraulics activities in China cover three main areas, namely, reactor core thermal hydraulics, safety-related thermal hydraulics, and fundamental thermal hydraulics.
This paper gives a brief summary of the ongoing R&D activities in these three areas with a focus on a few selected topics: (1) transversal mixing and nonuniform heat transfer distribution in fuel assemblies, (2) two-phase distribution at external reactor vessel cooling conditions, and (3) heat transfer of supercritical fluids. The state-of-the-art ongoing works and challenging aspects are presented and discussed.
