Generic Pressurized Water Reactor (GPWR) Simulator
with Digital Control Room HMI
Real Nuclear Operations Without the Cost of a Full-Scope Simulator
Traditional full-scope nuclear plant simulators require years to develop and millions of dollars to implement. GSE’s Generic Pressurized Water Reactor (GPWR) Simulator delivers the same high-fidelity modeling foundation used to train licensed operators—at a fraction of the cost and deployment time.
GPWR allows universities and research institutions to simulate plant behavior, operator decisions, and system interactions in a safe, controlled environment.
- Research & Human Factors: Extensive expertise in the design and licensing basis of plant systems. Our design solutions are developed to maintain and enhance system integrity while preserving licensing compliance.
- Control Room Design & Testing: Deep experience in electrical, instrumentation, and control systems for power plants, with specialized knowledge in medium- and low voltage systems and digital modernization.
- Nuclear Engineering Education: Comprehensive analysis and design services for power plant structures, including support systems and components essential to plant operation.
Not all generic sims are the same. GSE’s GPWR operates accurately across the full power range from 0%-100% power. High-fidelity nuclear simulation supports international research initiatives studying human performance in complex operational environments.

Facilities such as HAMMLAB at the Institute for Energy Technology (IFE) use similar simulation environments to study:
- Operator decision making
- Human-system interfaces
- Control room modernization
- Safety and operational performance
Researchers from utilities, regulators, and academic institutions across 20+ countries utilize these environments to advance nuclear safety and operational excellence.
With GPWR simulation, users can:
- Experience real nuclear plant system interactions
- Practice plant procedures and abnormal scenarios
- Develop team-based operational skills
- Study human-system interaction in complex environments
- Analyze plant performance and system response
