1. IAEA International Atomic Energy Agency How Should we Shape our Future PC Based Simulator Program? Chad Painter Nuclear Power Technology Development Section (NPTDS) May 2014

2. IAEA Simulator Enhancements Simulators need to continually evolve or they will become obsolete! OS and IT continues to evolve New operating system versions, require changes to software Touch screen technology, brings new opportunities to enhance learning experience 3D visualization tools also bring new learning opportunities Use of multi-screens more common place

3. IAEA Immediate changes based on our discussions Change PC-based to “basic principles” Add list of related publications Identify a version of IAEA distribution disc on our web site, so everyone knows current version. Incorporate Dr. Bereznai multimedia files into CANDU folder I need to work with IAEA to better define export control requirements

5. Other Enhancements Clearly identify AOO, DBA, and BDBA Include time advance option to speed up simulation Ability to output parameters to a spreadsheet, aids in analysis Modify BWR simulator to reflect Power/Feed water flow control as opposed to Power/Core flow map Add containment cooling and vent system to VVER simulator Incorporate the ability to modify plant parameters Incorporate “mathcad-like” files, assist in understanding basic physics

6. IAEA Do we need to upgrade our user documentation? Clearly distinguish between AOOs, DBA, and BDBA events Should we develop a IAEA document describing how best to use the simulators in a nuclear engineering curriculum? Would it be useful for the IAEA to host some sort of online forum for the sharing of best practices?

7. IAEA IAEA Learning Management System Web based Phase 1 course to understand reactor system basics Classroom Phase 2 course to work hands on with PC based simulators Benefit: minimize hotel & per diem costs for 2 week course What if we develop a Web based Video course?

8. IAEA Cloud Based Systems Provide platform independent software Improve global access Reduce cost to mail CD packages Allow better control of export sensitive technology

9. IAEA Plethora of Open Source Software Eclipse, Integrated Development Environment (IDE) Supports development of C++, JAVA, Python, Fortran and other codes; including Windows Builder (GUI builder software) Python and Java programming languages allow device independent software 3D visualization Blender, Sketchup, and VTK

10. IAEA Modelica-based Simulators? Modelica object-oriented, declarative, multi- domain modeling language component-oriented modeling of complex systems

11. IAEA Simulator Details? Severe Accident models Fuel performance models Dose prediction models e.g., effect of fuel failure on airborne levels in BWR steam plant Details related to other system components e.g., ability to change condensate inlet temperature and what the effects on condenser vacuum

12. IAEA What about Advanced Reactor Simulators? Integral water-cooled Small Modular Reactor High Temperature Gas-cooled Reactor Sodium-cooled Fast Reactor Lead-cooled Fast Reactor Molten Salt Reactor

13. IAEA What might the Future look like? Multi-screen mode with 3D visualization, incorporating touch screen technology, and built-in mathcad-like models

14. IAEA Next Steps……..group discussions Simulator Development and Future Needs Educational Applications and Needs Visualization technology and ideas for future Open Source Software and Web Applications
