FOREWORD
The IAEA has established a programme in nuclear reactor simulation computer programs to assist Member States in educating and training nuclear professionals in the operation and behaviour of nuclear power plants. The simulators enable hands-on training for nuclear professionals involved in teaching and training topics such as nuclear power plant design, safety, technology, simulation and operations. The simpler design of the simulators allows professionals to grasp the fundamentals without becoming lost in the details of a more complex full scope simulator. The objective is to provide, for various reactor types, insight and practice in reactor operational characteristics and their response to perturbations and accident situations.
Together with management and development, the IAEA regularly produces training material and provides training courses to assist professionals in Member States to understand the simulators and their associated technologies. This training is more cost effective and less time consuming than alternative methods and is highly suitable for Member States with limited resources.
This Exercise Handbook accompanies Training Course Series No. 65, Integral Pressurized Water Reactor Simulator Manual. It contains practical exercises as part of the educational and training material provided during IAEA training courses and workshops. The Manual provides an explanation of the theoretical concepts of integral pressurized water reactors and a description of the simulator’s features. The Exercise Handbook complements this by providing detailed, step by step operating instructions together with the required explanations to run various normal operations and transients in the simulator. The publications can be used both independently and together, and they serve as educational and training material for IAEA training courses and workshops. This publication provides comprehensive reference material to support human capacity building in all Member States improving their expertise in education and training related activities for small modular reactor technology.
The IAEA gratefully acknowledges the contribution of I. Parrado (Spain) to the preparation of this publication. The IAEA officer responsible for this publication was C. Batra of the Division of Nuclear Power.

1. INTRODUCTION
1.1. BACKGROUND
The International Atomic Energy Agency (IAEA) has a suite of nuclear reactor simulation
computer programs to assist its Member States in education and training. The objective is to
provide, for a variety of advanced reactor types, insight and practice in-reactor operational
characteristics and their response to perturbations and accident situations. To achieve this, the
IAEA arranges for the supply and development of a suite of basic principles nuclear power
plant simulators which are available for free to Member States upon request and are intended
for educational purposes. The IAEA also provides associated training material, sponsors
training courses and workshops, and distributes the documentation and computer programs.
The use of basic principle simulators to aid in teaching complex system interactions can
considerably improve students’ comprehension and retention of engineering course materials.
In addition, the use of simulators on nuclear fundamentals type training courses can greatly
add to trainees’ understanding of reactor operation and the role of various systems.
The IAEA’s existing suite of basic principles simulators are currently based on a variety of
large scale, water cooled nuclear reactor technologies. The basic principle simulator helps in
demonstrating the essential physical processes as well as fundamental system engineering
concepts. This type of simulator also serves training objectives such as providing an overview
of plant behaviour or a basic understanding of the normal as well as abnormal operation
modes.
Such simulators may consist of complete primary and secondary circuits, sometimes with a
reduced number of loops or redundancies. The scope of simulation focusses on the main
systems where auxiliary or supporting systems may be neglected. The control room or panels
very often have a fundamentally different design in comparison with conventional control
room design.
The IAEA’s suite of simulators is used on personal computers to develop understanding of the
various reactor designs as well as their operational characteristics. They are intended for
nuclear professionals involved in teaching and training on topics related to nuclear power
plant design, safety, technology, simulation and operations; and could also be used, in some
cases, for a broad audience of both technical and non-technical personnel as introductory
educational tool. The simulators are not expected to produce accurate results but do
demonstrate realistic trends and transients in response to changes made by the user.
In recent years the IAEA has seen an increase in the participation of its Member States in its
programme for the technology development of small modular reactors. Various designs are
under development in several Member States. A large number of the designs that are in
development are light water cooled and moderated small integral pressurized water reactors
(iPWRs). Common features of iPWR designs include modularity, passive safety systems for
core and containment cooling, and integrated design — where most or all primary
components are located inside the reactor vessel.
1.2. OBJECTIVES
The objective of this exercise handbook is to provide a basic set of pratical exercises to
understand various normal operations as well as possible transients in this type of reactor. It
also serves as a step-by-step guidance document during the training courses. Full instructions
2
on how to install the software and all of the background information is contained in the
accompanying Intergral Pressurized Water Reactor Simulator Manual (Training Course Series
No. 65).
1.3. SCOPE
This publication covers only a certain predefined list of standard operations and malfunction
transients. The simulator in itself is capable of simulating more transients and therefore users
can run various other transients depending upon his or her understanding level as well as the
capability of simulator. Sever accidents are out of scope of this simulator and therefore cannot
be simulated.
Most importantly, the responses manifested by the simulator, under accident situations,
should not be used for safety analysis purposes, despite the fact that they are realistic for
educational training.
1.4. STRUCTURE
The publication is divided into three sections. The first section provides the background
information along with the objectives, scope and structure of the document. The second and
third sections of this manual contain a set of exercises in normal and abnormal operation
respectively in order to help the user understand the working of an iPWR-SMR power plant.
Each exercise is made in the form of a table and contains five columns:
(a) Number of step in the exercise;
(b) Procedure step that indicates the user what has to be done;
(c) The display where the action has to be done;
(d) What is the expected response;
(e) A column where the user could indicate if the step has been done/succesful.
2. SIMULATOR EXERCISES FOR STANDARD OPERATIONS
This section contains the exercises required to allow the user to understand how to operate an
iPWR-SMR nuclear power plant under normal conditions.
In order to understand it, the following exercises are described:
1. Load maneuvering (10%) in turbine leading mode;
2. Load Maneuvering (10%) in reactor leading mode;
3. Reactor power decrease from 100% to 0% in turbine leading mode;
4. Reactor power rise from 0% to 100%;
5. Reactor trip and restart.
