Abstract Perfecting the induction process relies on fine-tuning every small detail. For the tool, this means the complex development process for the inductors using design software, high-precision production, and the correct positioning of the tool in the machine’s connection system. Applying different new and highly advanced 3D technologies such as FEM & CFD analysis and 3D printing of inductors will lead to a drastic increase of efficiency and the highest reproducibility for the entire process. When this happens, computer-aided accuracies of the inductors are compared with real manufactured inductors using 3D optical measurement methods and will reveal the advantages of this new process technology. The precision and process repeatability of this technology is showcased by various experimental test series’ that take the daily operational challenges for induction hardening as a benchmark.

The ongoing research at Texas A&M University (TAMU) aims to develop and implement measurement techniques to quantify fission product transport and related phenomena in a Gas-Cooled Fast Reactor (GCFR). This study summarizes the experimental measurements performed in a Proof-of-Concept Facility (PCF) to understand particle transport under various Reynolds numbers. Using high-resolution high-magnification optical measurement techniques, surrogate particle deposition was measured on the bottom wall surface of the PCF. The particle deposition over time was observed to decrease as the Reynolds number increased. In addition, the particle spatial distributions increased approaching the side wall of the PCF. This state-of-the art optical technique allows for the non-intrusive measurements of micron-sized particles near the wall surface.
