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.

Tritium in everyday water (potable water) is frequently of a level that is too low for measurement with conventional instrumentation that is affordable by small laboratories. Scintillation counters that can measure in fractions of Becquerels per litre are usually out of the reach of most laboratories, especially in developing countries. By concentrating the tritium by a known amount, it can reach measurable levels that can be converted back to the original concentration. Affordability of the concentrating process is vital in the overall process.
A simple concentrating process based on purification and electrolysis was designed and fabricated. The tritium isotope enrichment level, the volumetric reduction and the time frame required for the enrichment were determined using the simple designed and fabricated process, and an easily affordable scintillation counter.
The simple designed and fabricated system effectively concentrated the tritium in the sampled water several times the initial value. The enrichment resulted in the output product being measurable in a non-expensive scintillation counter.
