When Standard Diagnostics Reach Their Limits
Despite the widespread use of real-time monitoring systems, many vibration-related issues in critical assets—such as steam turbines, reactor coolant pumps, and generators—remain difficult to diagnose. Complex interactions between mechanical, fluid, and electromagnetic forces often generate vibration signatures that are difficult to interpret.
Engineers face an uncomfortable situation where they collect sufficient data, but still cannot pinpoint the exact root causes, leading to conservative derating, unnecessary shutdowns, and costly unplanned outages.
Inside the White Paper: Proven Methodologies for Nuclear Reliability
To secure the long-term operation of the existing fleet and support new build R&D, operators should move beyond basic predictive maintenance.
What you will find in this technical white paper is a proven 5-step implementation framework for nuclear operators, detailing how to:
- Deploy Portable Vibration Analyzers: Capture gap-free, high-frequency data in restricted environments where standard instrumentation falls short.
- Execute Advanced Dynamic Analysis: Utilize Operating Deflection Shape (ODS), synchronous order analysis, and Experimental Modal Analysis (EMA) to uncover hidden excitation sources.
- Ensure Regulatory Compliance: Standardize testing workflows to yield highly repeatable, traceable data that supports ASME NQA-1 and IEC standards.
- Refine Models & Safe Margins: Correlate experimental field measurements directly with simulation models to validate asset integrity.
Proven in the Most Demanding Energy Environments
These methodologies are actively used to solve critical issues on rotating machinery technically equivalent to those found in nuclear power plants.
