Simulation aids power station training
programme
Simulation software has played a key role in the development of a state-of-the-art, hands-on training programme to improve the skills of operators at Surry Power Station.
A state-of-the-art, hands-on training programme was developed at Surry Power Station to improve the skills of operators in the use of controller modules that operate steam generator power-operated relief valves The steam generator controller modules operate automatically or manually to open or close relief valves that allow for safe venting of pressures that build up in the reactor's three steam generators during shutdown

VisSim 7 provides a better physical understanding of model behaviour through 3D plots and animations as well as better simulating the noise in real-world systems with new random number routines.
Simulation software eases 3D animation
VisSim is a Windows-based program for the modelling and simulation of complex nonlinear dynamic systems, combining an intuitive drag-and-drop block diagram interface with a powerful simulation engine.
"I developed computer-based simulations that allow operators to change controller settings, analyse the effects of the changes, then explore them mathematically", said Hal Warren, Senior Instructor-Nuclear Training, Surry Power Station.
"This helps them develop a better understanding of the effects generated by each change".
Warren developed a second simulation that depicts how station equipment responds to certain types of emergency events.

Upgrade for dynamic simulation package
Visual Solutions has released VisSim Version 6.0 for Windows 95/98/2000/NT/XP.
"It also explores operation of the atmospheric dump valves in automatic and manual modes, as well as common system failures that can occur and the actions that need to be taken by operators", he said.
"The simulations can be used at an employee's workstation or can be projected in a classroom environment to provide a rapid method for understanding complex process controller concepts".
Warren's simulations were designed on a Pentium PC using VisSim modelling and simulation software.
He said the feedback received from trainees indicated an improvement in the assimilation and retention of the training material, and instruction time was reduced from 10 to 2h.
"The simulations also provided us with a new method of troubleshooting systems and equipment without impacting station operations", he added.
For his efforts, Warren was awarded a training excellence award from the American Nuclear Society for achievement, excellence and innovation in nuclear training.
The simulations were also recognised by the Institute of Nuclear Power Operations (INPO) during a 1995 plant evaluation.
The Training Centre at the Surry VA power station is tasked with providing continuing education for its operating personnel in a formal classroom environment.
VisSim is a visual block-diagram based modelling and simulation applications environment that runs on Windows and Unix/X platforms.
Along with VisSim/Real-Time addon software, it is an ideal tool for modelling controls and plant functions for the purpose of commissioning new processes and for training operators.
