Nuclear power plants - Instrumentation and control systems important to safety - Selection and use of wireless devices

This document establishes requirements relevant to the selection and use of wireless devices in instrumentation and control (I&C) systems important to safety used in nuclear power plants (NPPs). Those I&C systems may fully consist of wireless devices. NOTE The word “use” refers to the integration of the device, its qualification, administrative control, and every other activity that may be necessary to use the device in an important to safety application. This document applies to the I&C of new NPPs and to backfit of I&C in existing NPPs. Every wireless device or wireless system that is important to safety is in the scope of this document. Both fixed and mobile devices and all data types (voice, process data, etc.) are included within the scope if they provide a safety classified function. This document restricts the use of wireless devices to systems supporting category C functions according to IEC 61226, excluding explicitly their use for categories A and B. Non-safety devices and systems may use this document as guidelines, for example to ensure that important to safety devices are not disturbed. – Clause 5 describes the fundamental requirements regarding safety and cybersecurity. – Clause 6 gives wireless-specific requirements that have to be included in the system design. – Clause 7 describes the requirements for the selection and integration of wireless devices. – Clause 8 deals with electromagnetic compatibility and spectrum management. – Clause 9 gives wireless-specific requirements regarding cybersecurity. – Clause 10 describes the requirements for the qualification of wireless devices and their environment
