Advanced Earthquake Detection & Automatic Shutdown Solution for Nuclear Safety
Seeing is Believing.

QuakeLogic Inc. successfully completed the design, supply, and implementation of an advanced Seismic Reactor Trip System for a nuclear reactor facility in Idaho, USA. This project enhances operational safety by enabling rapid detection of seismic activity and triggering automatic protective actions to safeguard critical infrastructure.
Project Overview
In high-risk environments such as nuclear facilities, even minor seismic disturbances can pose significant safety concerns. The client required a reliable, real-time earthquake detection and response system capable of:
- Detecting ground motion with high precision
- Providing instant alerts to operators
- Automatically initiating reactor trip protocols
- Integrating with existing control and safety systems

QuakeLogic delivered a robust, redundant, and real-time seismic monitoring solution tailored to nuclear safety standards.
System Architecture
The installed system consists of:
1. Seismic Sensors – pALERT F330 (3 Units)

- High-resolution MEMS accelerometers
- Real-time ground motion detection
- Network-based data transmission
- Strategic placement for optimal structural coverage
2. Central Processing & Display – CUBE System

- On-site data processing and decision-making
- Real-time visualization on integrated touchscreen display
- Multi-sensor voting logic (N-of-M) for reliability
- Audible and visual alarm system
- Integration-ready outputs for reactor trip activation
How the System Works
- Continuous Monitoring
The three pALERT F330 sensors continuously measure ground acceleration. - Data Transmission
Sensor data is transmitted in real-time to the CUBE unit via a dedicated network. - Intelligent Decision Logic
The CUBE system applies N-of-M voting logic to eliminate false triggers and ensure reliability. - Automatic Reactor Trip
When predefined thresholds are exceeded, the system instantly triggers a reactor shutdown signal, minimizing risk. - Operator Awareness
The system provides clear visual and audible alerts for immediate situational awareness.

Key Features & Advantages
- High Reliability: Redundant sensor configuration ensures accurate detection
- Fast Response Time: Millisecond-level detection and triggering
- Fail-Safe Design: Independent operation even during network interruptions
- Scalable Architecture: Easily expandable for additional sensors
- Industrial Integration: Compatible with SCADA, PLC, and safety systems
- On-Site Processing: No dependency on cloud connectivity

Applications
This solution is ideal for:
- Nuclear reactors and research facilities
- Power generation plants
- Critical infrastructure and industrial facilities
- High-value equipment protection systems
Project Outcome
The deployed system provides the client with:
- Enhanced seismic safety compliance
- Reduced risk of structural and operational damage
- Improved automated emergency response capability
- Increased confidence in facility resilience
