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
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

Norway’s Halden reactor takes first step toward decommissioning
The government of Norway has granted the transfer of the Halden research reactor from the Institute for Energy Technology (IFE) to the state agency Norwegian Nuclear Decommissioning (NND). The 25-MWt Halden boiling water reactor operated from 1958 to 2018 and was used in the research of nuclear fuel, reactor internals, plant procedures and monitoring, and human factors.

RAPID (Real-time Analysis for Particle-transport In-situ Detection) leverages the innovative Multi-stage Response-function particle Transport (MRT) methodology to deliver real-time simulation capabilities for complex nuclear systems. RAPID solves for pin-wise, axially-dependent fission neutron distribution, critical/subcritical multiplication, and detector response. Novel algorithms for 3-D fuel burnup (bRAPID) calculation and 3-D reactor
kinetics (tRAPID) have been developed and validated using the Jozef Stefan Institute (JSI)’s TRIGA research reactor. Additionally, RAPID use for generation of ‘training’ and ‘testing’ datasets for development of AI/ML models and algorithms will be discussed.
Further, a multi-user virtual reality system (VRS) has been developed that provides a web application for input preparation, real-time simulation, and output processing and visualization in a virtual environment. For an introduction, please view the following demo https://www.youtube.com/watch?v=1Q2ytjBrmXc
Schedule
RAPID’s MRT methodology and formulation (15 min)
RAPID code system, its algorithms and their benchmarking and validation (75 min)
Break (10 min)
Demonstration of RAPID-2 (20)
VRS-RAPID demonstration (20 min)
Hands-on use by participants (40 min)
Requirements
There will be access to wireless internet so that the participants can have remote access to VRS-RAPID. The current version of VRS-RAPID is optimized for a Personal Computer using the Google Chrome browser, but it can be accessed through iPad, Tablet, etc. using any other browser.
To facilitate establishing individual accounts, participants are encouraged to contact Prof. Haghighat (haghighat@vt.edu) prior to the workshop.
