Embeded Workshop

RAPID Code System and its VRS Environment

Prof. Alireza Haghighat

Nuclear Engineering Program, Virginia Tech, Falls Church, VA, USA

RAPID (Real-time Analysis for Particle-transport In-situ Detection) is developed based on the MRT (Multi-stage Response-function particle Transport) methodology that enables its real-time simulation capability. The current version of RAPID is capable of simulating nuclear systems such as spent fuel pools, spent fuel casks, and reactor cores. RAPID solves for pin-wise, axially-dependent fission density, critical/subcritical multiplication, and detector response.

Additionally, 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

Topics to be covered:


  1. RAPID’s MRT methodology and formulation

  2. RAPID code system and benchmarking

  3. VRS-RAPID demonstration

  4. Hands-on use by participants


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. Participants are expected to bring their own devices.

To facilitate establishing individual accounts, participants are encouraged to contact Prof. Haghighat prior to the workshop.

The participation at the workshop is included in the conference fee.
To register to the workshop, please check the appropriate checkbox in the conference registration form.
The workshop will be held on Monday, September 9, 2019, in the morning, with the duration of 3 hours.
More information will be available shortly.
