A real-time simulation solution for precise and safe fuel refueling training

RFS (Refueling Machine Simulator) powered by MPSP

A real-time, simulation-based RFS training system designed to maximize the safety and precision of fuel refueling operations, reflecting next-generation nuclear power plant operating environments.

A high-precision, real-time RFS (Refueling System) training simulator.

Accurately reproduces position control of refueling equipment, fuel loading and removal, interlock logic, and safety scenarios.
Highly effective for training in equipment operation and emergency procedure response.

A core tool for enhancing training immersion and operational safety.

Expected Utilization Benefits

Application Area	Impact and Value
Refueling Training	Repetitive learning following procedures identical to real operating environments, without exposure to risk factors
Improved Equipment Operation Capability	Enhanced real-time decision-making through control panel operations, response timing, and emergency actions
Optimized Training for New Personnel	Structured and standardized training provided without location constraints
Practical Technology Verification	Equipment performance validation possible based on failure modes or scenario-driven conditions

This is not merely a virtualization technology, but a human-centered advanced technical training solution that considers operator responsibility, safety assurance, and environmental sustainability.

The RFS simulator is an integrated simulation platform that extends its value across technology transfer, on-site operator training, and customer system integration.
