The International Atomic Energy Agency (IAEA) is developing an Advanced Reactor Simulation (ARS) software and associated training package for distribution to its Member States. It is a desk-top system using a personal computer with interactive controls. The plant types include PWR, BWR and PHWR in 600 MWe range. An example run using Westinghouse AP600 plant data for a medium-sized loss-of-coolant accident is presented. It demonstrates the simulator's reproduction of the transient behavior of the passive emergency safety systems.

 

Introduction

The IAEA assists its Member States in the introduction and experience of nuclear power. One element of the IAEA’s programme is the simulation of the operation of nuclear power plants, on computer.

Recently IAEA has published a technical document on the design and development status of small and medium sized reactors.[1] Subsequently it has consulted experts of several Members States in evaluation of the feasibility and defining the scope of a possible training program. The concluded objective is to make a desk-top simulator and training material available to all Member States; as an educational tool to better understand the behavior of nuclear reactors and for training purposes.

The intended target group includes a wide range of individuals, from post-graduate students to experts dealing with the introduction or expansion of nuclear power in their country.

The first training workshop on reactor simulation is planned to be held in 1997. During the workshop the IAEA-ARS software and training package will be distributed to the attendees. They will be expected to become instructors in their own countries for further distribution of the knowledge. As a result, a training program centered on the use of an Advanced Reactor Simulation (ARS) software with associated training package was formulated.
