NRC engineers share their expertise at the University of Puerto Rico
Robert Roche-Rivera and Marcos Rolón-Acevedo are licensed professional engineers who work at the U.S. Nuclear Regulatory Commission. They are also alumni of the University of Puerto Rico–Mayagüez (UPRM) and have been sharing their knowledge and experience with students at their alma mater since last year, serving as adjunct professors in the university’s Department of Mechanical Engineering. During the 2023–2024 school year, they each taught two courses: Fundamentals of Nuclear Science and Engineering, and Nuclear Power Plant Engineering.

The aim of the work is to develop the fabrication technology of a small curved tungsten (W) macro-brush–type geometry using a vacuum brazing technique. Taking the design concept of the ITER divertor dome, the present mock-up has scaled down more than ten times in size. A feasibility study of the curved brazing was done, and design and fabrication of the special fixture for the curved profile brazing were carried out. The vacuum brazing technique was used to develop the joining of tungsten tiles in the curved profile of a CuCrZr block (heat sink) using silver-free brazing alloy (NiCuMn-37) with a specially designed custom-made fixture (Type 304 stainless steel). Nondestructive testing, particularly the ultrasonic immersion technique, was incorporated to inspect the quality of the brazed joint in the mock-up. The hardness value (HV) measured on the copper alloy was found to degrade from 143 to 46 HV (before and after brazing). The results of the experimental activity and methodology adopted to fabricate the small-sized trial W mock-up are presented and discussed in the paper.
