Products for the Nuclear Power Industry

RELAP5-HD™ Real-Time Solution

JADE™ and SimExec™ Tools
SimExec is the glue that binds all of the simulation technology together and manages all of the real-time tasks. SimExec is applicable for Microsoft Windows as well as LINUX/UNIX operating systems. It provides a true multi-user environment for your team of model developers or maintenance engineers.

Xtreme™ and OpenSim™ Tools

DesignEP and PSA-HD
GSE’s PSA-HD software integrates EPRI’s Modular Accident Analysis Program (MAAP5) into a real-time simulation environment connected to all of the other plant systems in the simulator. This gives realistic plant behavior, allowing operators to assess accident scenarios in a holistic environment, practice severe accident management guidelines and experiment with alternative action scenarios.
DesignEP integrates and simulates the operation and performance of the major systems related to the nuclear reactor core and containment at both PWRs and BWRs. It allows you to view the interaction, and cause and effect, not only between multiple systems within a plant, but also between multiple units at a single site.

REMARK™ Core Modeling

Integrated AV System for Instructor Stations
Products for the Thermal Power Industry

JADE™ and SimExec™ Tools
JADE is a set of integrated, high-fidelity modeling tools that provide full fossil plant simulation capabilities for fluid dynamics, electrical, logic and control systems. The JADE suite consists of JTopmeret, JElectric, JLogic, JControl and JDesigner.
SimExec is the glue that binds all of the simulation technology together and manages all of the real-time tasks. SimExec is applicable for Microsoft Windows as well as LINUX/UNIX operating systems. It provides a true multi-user environment for your team of model developers or maintenance engineers.
Products for the Petroleum Industry

JPro™ Dynamic Simulation Software
JPro simulation software is specifically designed for the refining, oil and gas, and chemical process industries. It is an easy-to-use tool kit that process engineers can use to develop high-fidelity, real-time simulations customized to specific processes or control systems. A robust graphical user interface provides simple drag-and-drop functionality. An extensive object library of process modules and standard equipment lets you intuitively build your process model quickly, and scale it easily. You can build a full or partial simulation model. The result is a custom, high-fidelity simulation model that can operate in real time, fast time or slow time.
