Background
Real-time simulators came
to the nuclear industry as
training tools in the 1970s
– Limited computing power
– Limited fidelity and
realism
– Hand crafted software
– “Tuned” to make it work
– Used for training
Today’s NPP simulator is
high fidelity
– Predictive models
– Engineering grade
– Multiple uses

Introduction
• Digital instrumentation and control
(I&C) and digital control rooms
• New plants designs and the life
extension of older plants require
validation of these system designs.
• The real-time or dynamic simulator is
playing a valuable role in the design
of these new systems.

5. 5
Critical Issues on New Plant Design
and Construction
• Plants are using new technology.
• New control and information systems are being introduced that
have extensive and complex control and logics.
• Plants will integrate disparate technologies often for the first time.
• Coordination of technology providers for the unit operations and
the integration and design of the plant is a huge concern.
• Aggressive scheduling is required to improve the return on
investment.

6. 6
Requires High Fidelity Predictive
Models
• INL’s RELAP5-3D
Thermohydraulic Model
• Studsvik’s S3R Neutronics Model
• EPRI’s MAAP5 Severe Accident
Code
• GSE’s High Fidelity JADE
Modeling Tools
The key! Predictive models are necessary for
engineering simulators.

7. Case Study: Mochovce Nuclear Plant

8. 8
Two New Units at Mochovce
• Modern power plant consisting of
four Soviet VVER 440/V-213
– Units 1&2 operated since 1998 and
2000
– Units 3&4 to be started up in 2015
and 2016
• Owner: Slovenské Elektrárne and
Enel
• Primarily modern Siemens controls
and a modern control room with a
traditional plant design

9. 9
Project Objective
• High-fidelity full-scope simulator
– All new system models and controls
– New control room panels including emergency control
room
– Siemens and other vendors sub-contractor to GSE
– Simulator delivery critical to new plant schedule (critical
path)
– Plant controls still in development as simulator was
being constructed

Project Challenges
• Plant under construction /
Build simulator parallel with
plant / DCS database
availability and changes
• Size and complexity of the
project with unique features
DCS & backup panels
• Integrate with third party
vendors, and complex and
new technologies

12. 12
3rd Party Integrated Software
The simulator integrated many third party new
and complex technologies:
– Siemens /Areva DCS
– Invelt/Skoda Turbine Control System
– Skoda Reactor Rod Control System
– Rolls Royce Ex-core System
– SNIIP In-core System
– ZAT Electrical Distribution/Synchronization
– EnergoData Dispatching Center
– SafeCo Fire Detection and Protection System –
Stimulated

Reduce design cost and project risk for the
following:
– Validate plant system process designs
– Design & validate digital I&C strategy
– Design & validate human machine interface
– Use as a platform for human factor engineering (control
room design)
– Validate plant operation procedure
