IAEA Collection of PC-Based Simulators for Education


WWERThe International Atomic Energy Agency (IAEA) has established a programme in nuclear reactor simulation computer programs to assist Member States in educating their nuclear professionals. The objective of the programme is to provide insight and understanding in the operational characteristics, reactivity control systems, safety systems, and response to transients and accident situations for a variety of common nuclear power plants. To achieve this, the IAEA arranges for the development and distribution of simulation software, and corresponding training materials, sponsors training courses and workshops, and distributes computer programs and documentation.


Currently the IAEA has Nuclear Power Plant simulation software available for distribution that simulate the behaviour of the following reactor types:

  • 4 Pressurized Water Reactor (PWR) Plant Simulators
    • Conventional two-loop PWR
    • Korean-type PWR
    • Russian-type PWR
    • Advanced Passive PWR
  • 2 Boiling Water Reactor (BWRs) Plant Simulators
    • Advanced BWR
    • Advanced Passive BWR
  • 2 Pressurized Heavy Water Reactor (PHWR) Plant Simulators
    • Conventional PHWR
    • Advanced PHWR

BWRThese desktop simulator codes provide insight and understanding of the designs as well as a clear understanding of the operational characteristics of the various reactor types. The simulators operate on personal computers and are provided for a broad audience of technical and non-technical personnel as an introductory educational tool. The preferred audience, however, are faculty members interested in developing nuclear engineering courses with the support of these very effective hands-on educational tools. The application of the simulator programs is limited to providing general response characteristics of selected types of power reactor systems and they are not intended to be used for plant-specific purposes such as design, safety evaluation, licensing or operator training.

PWR These simulators, including the associated documentation, are distributed at no cost to interested parties in IAEA Member States. Furthermore, the IAEA sponsors training courses and workshops on a regular basis, and would also be willing to support additional training events on this topic at the request of Member States. To request the simulators please fill out this simulator request form. The completed form should be sent to the competent official authority (Ministry of Foreign Affairs, National Atomic Energy Authority, or to the applicant's Member State Permanent Mission to the IAEA in Vienna, Austria) for transmission to Ms Marina Gam, the International Atomic Energy Agency, P.O. Box 100, Vienna International Centre, A-1400 Vienna, Austria.

Feedback on the use of these simulators would be appreciated and should be sent to Mr. Chad Painter


Workshops on PC-Based Simulator for Education

Since 1997, eighteen workshops have been held, in Egypt, Saudi Arabia, the Republic of Korea, Italy, Spain, the USA and in Vienna. The most recent workshop was held November 4-15, 2013 and was sponsored by TECNATOM.

Planning for a 2014 course is underway. Download the simulator request form
