IRIS is an advanced, integral, light-water-cooled, pressurized reactor of medium generating capacity (1000 MWt or 335 MWe). It is being developed by an international team led by Westinghouse that includes over 20 organizations from 10 countries. Basic IRIS design features will be presented, together with its main safety characteristics. Its unique “safety-by-design”™ approach allows significant simplification of the passive safety systems, improving safety while simultaneously reducing the overall cost. IRIS allows sequential introduction of single or twin-modules to match the energy demand growth. Its moderate size and short construction time significantly reduce the financial burden and present a competitive solution both for mature markets and for smaller/emerging markets with limited grid capacity or smaller utilities with limited financial resources. Selected research topics related to IRIS development will be highlighted, including shielding studies performed at Georgia Tech.


Dr. Bojan Petrovic joined Georgia Tech in 2007 as a Professor at the Nuclear & Radiological Engineering and Medical Physics Programs. Prior to that, he was a Fellow Scientist at the Westinghouse Science and Technology Department in Pittsburgh, Pennsylvania, where he was involved in advanced reactors design. Dr. Petrovic holds a B.Sc. degree in mathematics, and M.S. and Ph.D. degrees in Nuclear Engineering. Areas of his research interest include reactor physics and transport theory, advanced reactors design, and application of nuclear technology to industry and medicine.
