IEC TR 62987:2015

IEC TR 62987:2015 provides technical guidance for nuclear power plants with a focus on instrumentation and control systems important to safety, particularly the use of Failure Mode and Effects Analysis (FMEA) and related methods to support system justification. It is relevant when engineering teams need a structured, documented evaluation of how safety-related control systems may fail and how those failure effects are assessed. For organizations working in nuclear safety, technical review, and conformity assessment, the document supports disciplined risk management and engineering documentation.

Overview of IEC TR 62987:2015

This technical report addresses how FMEA and related analytical methods can be used to justify systems that perform safety-important functions in nuclear power plants. Its likely purpose is to help teams build a defensible technical assessment of system behavior, failure modes, and supporting evidence during design review or validation activities. IEC TR 62987:2015 is especially relevant where documented evaluation is needed to demonstrate operational consistency, support engineering specification decisions, and align analysis methods with safety-focused compliance workflows.

Compliance applications of IEC TR 62987:2015

IEC TR 62987:2015 may be used in engineering, verification activities, and procurement review for nuclear instrumentation and control systems that require safety justification. It can support technical assessment of control architectures, assessment reports, and laboratory evaluation programs where failure behavior needs to be understood and recorded. In practice, the document is useful for teams preparing technical validation evidence, organizing conformity assessment files, and reviewing whether proposed equipment and system designs are suitable for safety-related applications.

Importance of compliance with IEC TR 62987:2015

Using IEC TR 62987:2015 helps organizations apply a consistent analytical basis when assessing failure effects in systems important to nuclear safety. That consistency can improve safety decision-making, reduce review gaps, and strengthen the evidence package used in procurement, quality assurance, and regulatory preparation. For engineering groups, it also supports clearer traceability between failure analysis, design choices, and acceptance criteria, which is valuable during testing workflows and conformity assessment preparation.
