Nuclear Power Generation
Reliability
The increased component failure risk of aging reactors can lead to operation at reduced power or plant shutdowns
Performance
Difficulty to locate performance losses and sensor drifts
Decision-making
Need to build trust and organizational agility in problem solving and risk recognition.
Our Solution
Metroscope diagnoses steam cycle performance losses. The steam cycle or secondary systems account for 70% of reliability problems and can include many simultaneous and latent faults making these systems complex to analyze.
A Metroscope model can usually identify over 80 unique faults impacting power generation and availability
Tailored for each plant, our nuclear models have ~10,000 equations, simulating both nominal behavior and fault scenarios
Use case
Earlier detection of a heat exchanger tube rupture
- Tube rupture was detected at 3kg/s, instead of 9kg/s with standard practice
- Implementation of Metroscope allowed optimization of planned maintenance and equipment lifetime extension
Key benefits
Greater power output
Probability of plant shutdown and MWe losses are decreased due to equipment issues (e.g. at the condenser, MSRs, or feedwater reheaters)
Enhanced maintenance decisions
Fast and reliable process diagnosis can inform maintenance
Asset
