IEEE 379-2014

379-2014 is a technical standard for failure criterion in nuclear power generating station safety systems, with a focus on how components and circuits are judged when safety performance is at stake. It is relevant to engineering decisions involving devices, systems, and station-level protective functions where clear pass or fail expectations help support consistent design and evaluation. In nuclear applications, that kind of clarity is important for managing risk, supporting compliance, and maintaining dependable safety-related operation.

Overview of 379-2014

This standard addresses failure criterion used in the context of nuclear power generating station safety systems. Its purpose is to provide a defined basis for determining when equipment, circuits, or related functions should be considered failed, which can influence design reviews, testing, and maintenance planning. For engineers working with safety-related components, 379-2014 helps establish a more consistent technical framework for judgment and documentation. The result is better alignment between design intent, operational expectations, and safety-focused evaluation practices.

Typical use cases

379-2014 is typically consulted when assessing safety system behavior in nuclear power station engineering, especially for circuits, control elements, and device-level functions that must perform reliably under defined conditions. It may be used during design verification, failure analysis, acceptance testing, or maintenance reviews for protective and safety-related equipment. The standard is also relevant when teams need a common failure definition for documenting engineering decisions across components that contribute to station safety functions and overall operational readiness.

Why it matters

In nuclear power applications, a clear failure criterion helps reduce ambiguity in design control, testing, and compliance activities. 379-2014 supports more consistent evaluation of safety systems by giving engineers a defined reference for when a condition should be treated as a failure. That matters for procurement specifications, troubleshooting, and risk reduction because even small differences in interpretation can affect safety-related decisions. Using the same criterion across teams also helps improve traceability and consistency in technical records.
