set points, desired power level, reactivity insertion, and flow rate variation. Multiple
screens are available to obtain information during simulation. The display options
that can be selected are similar to those for the PWR simulation.
The BWR simulation has many screens and different settings to adjust in order to
create different models for real-life situations.

15.3.3 How to obtain an IAEA simulator?
The International Atomic Energy Agency (IAEA) sponsors the development and dis-
tribution of nuclear plant simulators for training and education. The simulation plat-
forms are developed for IAEA by commercial organizations. These simulators are
available to university professors and engineers of IAEA member states for use in
teaching the safety aspects and operation of nuclear power plants.
IAEA distributes the software and relevant documentation at no cost to request-
ing parties from member states and is made available through a SharePoint located
within IAEA’s Nucleus website. The requesting person/organization must register at
the following website to obtain a Nucleus login ID:
https://nucleus.iaea.org/Pages/default.aspx
Mail the completed Request Form to: Simulators.Contact-Point@iaea.org
