System Structure & Components
The HIMA NIACO2 system features a highly integrated and redundant architecture, with core components designed for the unique operational needs of nuclear power plants:
- Core Control Unit (CPU): The “brain” of the system, responsible for executing core safety logic and control algorithms with high precision and real-time performance.
- Power Module: Delivers stable power supply for the entire system, with mandatory dual power input for redundancy and fault tolerance.
- I/O Subrack: Interfaces with on-site nuclear power plant sensors and actuators; each subrack is configured with multiple I/O modules for multi-point signal collection and control.
- Communication Module: Enables reliable data transmission with upper-level systems (e.g., SCADA) and other on-site controllers, ensuring seamless information exchange in nuclear power plant control networks.
- Heat Dissipation Assembly: Fanless heat dissipation structure, engineered for efficient heat transfer to maintain stable system operation under high-temperature conditions in nuclear power facilities.

Key Application Areas
HIMA NIACO2 is the premier SIS solution for safety-critical systems in nuclear power plants, with core applications including:
- Reactor Protection System: Monitors and controls key operating parameters of nuclear reactors, ensuring reactor operation within strictly defined safety limits at all times.
- Radiation Monitoring System: Real-time detection of radiation levels inside nuclear power plants, with automatic emergency plan triggering for abnormal radiation values.
- Emergency Shutdown System (ESD): Instantly initiates automatic emergency shutdown procedures upon detection of dangerous signals, preventing safety hazards from escalating.
- Cooling System Control: Maintains the normal operation of nuclear reactor cooling systems, eliminating the risk of overheating accidents and ensuring reactor thermal stability.

Installation & Maintenance Guidelines
Professional Installation Requirements
- Cabinet Mounting: Install the system in industrial cabinets compliant with IEC 60204-1 standards, with reliable cabinet grounding to meet nuclear power plant electrical safety specifications.
- Heat Dissipation Considerations: While the fanless design minimizes heat-related failures, ensure adequate natural ventilation in the cabinet to prevent long-term heat accumulation and maintain optimal operating temperature.
- Power Connection: For 24V DC power access, strictly check polarity and use industrial-grade cables that meet nuclear power plant specification requirements; ensure stable connection for dual power supply inputs.
____________________________________________________________________________________________
Standard Maintenance Protocols
- Regular Inspections: Periodically check power voltage fluctuations, terminal block tightness, and the integrity of communication lines to eliminate potential hidden faults in advance.
- Spare Parts Management: As a nuclear power industry-dedicated device, it is recommended to stock key spare modules (e.g., I/O modules) on-site to ensure rapid replacement and minimize downtime in case of faults.
- Troubleshooting: The system is built with a self-test function; in the event of a fault, first check the system log and self-test indicator lights for quick fault localization and resolution
