IMAS
Developed to perform comprehensive "fatigue monitoring" the AMTEC IMAS system became a primary tool to long term safety and availability of nuclear power plants.
Major task of the system
Monitoring of mechanical and thermal loads of systems, structures and components as a basis for assessment.
Scheme am function
- monitoring of loads using local sensors
(temperature, displacement, deformation, strain, pressure, force, …) - correlation to operation state / transient
(internal pressure, temperature, flow, valve position, …) - continuous monitoring in an independent network
- scan rate depending on task
- independent data storage and documentation
Highlights
- modular design
(flexible customization to different tasks) - continuous monitoring of different transducers
- quasi-static and dynamic measurements
- nearly unlimited input channels
- continuous check of limits
- transient recording
- in case of event: mail to person in charge (e.g. system engineer)
- access to data via utility network
- database for evaluation and assessment
- long-term documentation
