RESEARCH REACTOR SIMULATOR

The research reactor simulator is a fast and robust PC based simulator of a small pool type research reactor developed for the purpose of:

PHYSICS
- Low power reactor, thermal power lower than 1MW
- Reactor physics with simple feedback
- For training and education
- Robust, fast, works on PC
- NOT for thermal hydraulics
- NOT for accident analyses
SIMULATION
- Point kinetic with external source
- Six group approximation
- Fourth stage Runge-Kutta integration
- 1 millisecond time step
- Xenon poisoning
- Temperature feedback effects
- Pulse operation
- Heating of primary water
- Automatic SCRAM
- Simulation speed from 0.01x slow motion to 1000x real time
TECHNICAL SPECIFICATIONS AND SYSTEM REQUIREMENTS
- No processor load for the graphical user interface
- 40 frames per second
- Custom elements for faster visualization
- Requires OpenGL 3.3 or newer
- Can run on an average computer or laptop
- Compiled for 64 bit operating systems
- Cross platform (Windows 7, WIndows 8, Windows 10, Mac OS, Linux)

Completely customizable settings allow user freedom to simulate their own reactor

DEMO VERSION

The demo version is a heavily stripped down version of the Research reactor simulator.
Keep in mind that this version has most of the features disabled (only allowing the user to move the regulating rod and to use stable power modes [Ctrl + D and Ctrl + F]).
You can download this version of the simulator HERE.

To use the program, just extract the files in the .zip archive to any folder.
Then, just execute the file named "Research reactor simulator [demo].exe".
Keep in mind that the two files contained within the .zip archive must be in the same folder when the program is executed.

SYSTEM REQUIREMENTS
  • 400MB of RAM
  • About 2MB of disk space (the simulator saves data to the disk while running, so this number may increase a little)
  • A graphics driver that supports OpenGl 3.3 or newer
  • C++ redistributable package (there is a good chance your computer already has it installed)

You may download this version of the manual HERE.

The Jožef Stefan Institute is the leading research institution in Slovenia and has been operating a TRIGA research reactor for more than 50 years. Reactor physics division at the JSI has more than 30 years of experience in reactor calculations and performing measurements of reactor physical parameters at research reactors and nuclear power plant Krško. The reactor simulator was developed by two enthusiastic students (Jan Malec and Dan Toškan) of physics at the Faculty of Mathematics and Physics, University of Ljubljana under supervision of adjunct professor of reactor physics Luka Snoj, also serving as head of the reactor physics division at the Jožef Stefan Institute.
