ASME OM-2-2024

Component Testing Requirements at Nuclear Facilities

ASME OM-2-2024 focuses on Component Testing Requirements at Nuclear Facilities and is part of the ASME Operation and Maintenance (OM) standards. This standard provides guidelines for inservice testing (IST) of components such as pumps, valves, and dynamic restraint devices at nuclear power plants. The goal is to ensure that these components are operationally ready to perform their intended functions through regular testing and monitoring for degradation trends.

The key features of ASME OM-2-2024 include:

1. Applicability to Diverse Reactors: While originally developed for water-cooled nuclear power plants, this standard addresses the needs of new and advanced reactors with different designs.
2. Focus on Safety and Functionality: It emphasizes ensuring components are correctly sized, properly specified, and made from materials compatible with operational conditions like system pressures, temperatures, and chemistry.
3. Degradation Monitoring: By trending degradation, the standard aims to identify and correct potential issues before components fail.
4. Accommodations for Online Testing: Recognizing operational constraints, the standard adapts testing methods for components that cannot be fully tested while the plant is online​
