Webinar: MC&A and safety in advanced reactors in focus
Towell
Russell
Prasad
The American Nuclear Society’s Nuclear Nonproliferation Policy Division recently hosted a webinar on updating material control and accounting (MC&A) and security regulations for the evolving field of advanced reactors.
Moderator Shikha Prasad (CEO, Srijan LLC) was joined by two presenters, John Russell and Lester Towell, who looked at how regulations that were historically developed for traditional light water reactors will apply to the next generation of nuclear technology and what changes need to be made.

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.
