IEEE P1786/D2, Nov 2021

IEEE P1786/D2, Nov 2021 is a draft guide for applying human factors principles to computerized operating procedure systems (COPS) used at nuclear power generating stations and other nuclear facilities. It focuses on how these systems support operators during procedure-driven tasks, where clear presentation, workflow logic, and dependable interaction can affect plant performance and safety. For organizations involved in computing and nuclear engineering, this document helps frame design and evaluation decisions for operator-facing software.

IEEE P1786/D2, Nov 2021 overview

This draft guide addresses the human factors considerations that arise when operating procedures are delivered through computerized systems in nuclear environments. IEEE P1786/D2, Nov 2021 is relevant to interfaces, task support, navigation, and information presentation where operators rely on software to follow or manage procedures. As a draft technical document, it is useful for aligning design intent with operational demands, especially in settings where procedure execution must remain consistent, traceable, and easy to use under time-sensitive conditions.

Typical use cases

Typical use cases include computerized procedure systems in control rooms, training environments, and plant support tools that guide operators through routine or abnormal operating steps. IEEE P1786/D2, Nov 2021 may be applied when designing or reviewing displays, prompts, alerts, branching logic, and confirmation steps for nuclear facility workflows. It is also relevant when teams assess whether a COPS implementation supports operator decision-making, reduces ambiguity, and fits established operating practices across generating stations and related nuclear systems.

Why this standard matters

This standard matters because procedure systems in nuclear settings must support safe, consistent execution with minimal opportunity for confusion or missed steps. IEEE P1786/D2, Nov 2021 can help organizations evaluate whether computerized procedures are designed with operator workload, error prevention, and usability in mind. That is important for specification review, procurement, testing, and design control, since poorly aligned interfaces can increase operational risk or make procedures harder to follow during normal or abnormal conditions.
