ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
Division Spotlight
Thermal Hydraulics
The division provides a forum for focused technical dialogue on thermal hydraulic technology in the nuclear industry. Specifically, this will include heat transfer and fluid mechanics involved in the utilization of nuclear energy. It is intended to attract the highest quality of theoretical and experimental work to ANS, including research on basic phenomena and application to nuclear system design.

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.

Westinghouse Electric Company recognizes the importance of supporting students pursuing a career in reactor physics. For this reason, Westinghouse will be sponsoring the first 100 student workshop registrants by covering their fees. Contact registrar@ans.org for a discount code before registering. Limited space available in each workshop. Once these seats are filled, you will be put on a waitlist. You must request a discount code before registering. No refunds will be made if you do not contact us before registering.
Organized by Joshua Hanophy (INL), Hansol Park (ANL) through the Advanced Reactor Technology and Nuclear Energy Advanced Modeling and Simulation Programs
The goal of the training session is to gain familiarity modeling the running-in phase of pebble bed reactors (PBRs) with the MOOSE-based tools Griffin and Pronghorn. Griffin includes capabilities for neutronics and depletion calculations and provides power densities to Pronghorn. Pronghorn uses the power densities to calculate temperatures using a porous medium flow model and user input thermal-hydraulic conditions as well as simplified models for the pebble bed reactor structures. Griffin can use pregenerated multigroup libraries for cross sections or a new feature that enables using its own cross sections generated online. This workshop will provide hands-on exercises for online cross section generation, run-in phase modeling with Griffin, thermal-hydraulics modeling with Pronghorn, and multiphysics running-in modeling including a control rod withdrawal event from a non- equilibrium core.
The training will be conducted via the INL High Performance Computing (HPC) center. Trainees can either apply for: A) an INL HPC account and code licenses directly via (https://inl.gov/ncrc/) or B) temporary INL HPC account and temporary access to the codes. Either way, details on the INL’s Nuclear Computational Resource Center training signup process will be shared with registered participants. Trainees must bring their own laptops. Details on the process will be shared with registered participants. Note the following cutoffs for INL HPC account and license applications:
Cutoff for U.S.A. nationals INL HPC account and licenses is April 15th, 2024.
Cutoff for foreign nationals INL HPC account and licenses is March 1st, 2024.
