IEEE P382/D4, July 2019

P382/D4, July 2019 is a technical standard for related actuators used in nuclear power generating stations and other nuclear facilities. It addresses component-level requirements that support controlled operation of devices within nuclear systems, where dependable performance and traceable specification are important. In this context, the document is relevant to engineering, procurement, and verification activities that depend on consistent actuator design and qualification expectations. For projects working under P382/D4, July 2019, it helps define a clear basis for compliant equipment selection and review.

About P382/D4, July 2019

This standard focuses on related actuators in nuclear environments, where mechanical movement, control response, and interface behavior can affect overall system reliability. P382/D4, July 2019 is best understood as a specialized requirements document for equipment associated with components, circuits, devices, and systems in nuclear power applications. It is typically used to support design consistency, technical evaluation, and documentation review for actuators that may be installed in safety-related or closely controlled plant systems.

Where is P382/D4, July 2019 used?

P382/D4, July 2019 is commonly relevant in nuclear power generating stations and other nuclear facilities where actuators are used to operate valves, dampers, or other controlled mechanisms. It may be applied during equipment specification, supplier assessment, maintenance planning, and engineering review for plant systems that rely on accurate motion and dependable actuation. The standard is particularly useful when a project needs a clear reference for related actuator selection and performance expectations in a nuclear setting.

Importance in practice

In practice, P382/D4, July 2019 helps reduce uncertainty in the design and procurement of actuator-related equipment for nuclear service. Clear technical requirements can support safer integration, more consistent testing, and better alignment between engineering intent and delivered hardware. For owners, designers, and suppliers, the standard can also improve traceability and help manage risk when equipment must perform predictably under controlled plant conditions. That makes it valuable for compliance and long-term reliability decisions.
