NUCLEAR POWER PLANTS – INSTRUMENTATION AND CONTROL
SYSTEMS IMPORTANT TO SAFETY – SELECTION
AND USE OF WIRELESS DEVICES

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
a) Technical background, main issues and organization of this document
This document sets out requirements applicable to wireless devices that are used to perform
functions important to safety in nuclear power plants (NPPs).
It is intended that this document be used by operators of NPPs (utilities), systems evaluators
and by licensors.
b) Situation of this document in the structure of the IEC SC 45A standard series
IEC 62988 is a third level IEC SC 45A document covering the selection and use of wireless
devices in instrumentation and control (I&C) systems important to safety used in NPPs.
For more details on the structure of the IEC SC 45A standard series, see item d) of this
introduction.
c) Recommendations and limitations regarding the application of this document
It is important to note that this document is applicable to all important to safety systems
containing wireless devices, including systems performing category A and B functions (and in
such systems, wireless devices are prohibited by this document). Therefore, only systems
performing category C functions are required to follow the requirements of this document.
To ensure that this document will continue to be relevant in future years, the emphasis has
been placed on issues of principle, rather than specific technologies.
d) Description of the structure of the IEC SC 45A standard series and relationships
with other IEC documents and other bodies' documents (IAEA, ISO)
The top-level documents of the IEC SC 45A standard series are IEC 61513 and IEC 63046.
IEC 61513 provides general requirements for I&C systems and equipment that are used to
perform functions important to safety in NPPs. IEC 63046 provides general requirements for
electrical power systems of NPPs; it covers power supply systems including the supply
systems of the I&C systems. IEC 61513 and IEC 63046 are to be considered in conjunction
and at the same level. IEC 61513 and IEC 63046 structure the IEC SC 45A standard series
and shape a complete, coherent et consistent framework establishing general requirements
for instrumentation, control and electrical systems for nuclear power plants.
IEC 61513 and IEC 63046 refer directly to other IEC SC 45A standards for general topics
related to categorization of functions and classification of systems, qualification, separation,
defence against common cause failure, control room design, electromagnetic compatibility,
cybersecurity, software and hardware aspects for programmable digital systems, coordination
of safety and security requirements and management of ageing. The standards referenced
directly at this second level should be considered together with IEC 61513 and IEC 63046 as
a consistent document set.
At a third level, IEC SC 45A standards not directly referenced by IEC 61513 or by IEC 63046
are standards related to specific equipment, technical methods, or specific activities. Usually
these documents, which make reference to second-level documents for general topics, can be
used on their own.
A fourth level extending the IEC SC 45 standard series, corresponds to the Technical Reports,
which are not normative.

SIST EN IEC 62988:2022
– 6 – IEC 62988:2018 © IEC 2018
The IEC SC 45A standards series consistently implements and details the safety and security
principles and basic aspects provided in the relevant IAEA safety standards and in the
relevant documents of the IAEA nuclear security series (NSS). In particular, this includes the
IAEA requirements SSR-2/1, establishing safety requirements related to the design of nuclear
power plants (NPPs), the IAEA safety guide SSG-30 dealing with the safety classification of
structures, systems and components in NPPs, the IAEA safety guide SSG-39 dealing with the
design of instrumentation and control systems for NPPs, the IAEA safety guide SSG-34
dealing with the design of electrical power systems for NPPs and the implementing guide
NSS17 for computer security at nuclear facilities. The safety and security terminology and
definitions used by IEC SC 45A standards are consistent with those used by the IAEA.
IEC 61513 and IEC 63046 have adopted a presentation format similar to the basic safety
publication IEC 61508 with an overall life-cycle framework and a system life-cycle framework.
Regarding nuclear safety, IEC 61513 and IEC 63046 provide the interpretation of the general
requirements of IEC 61508-1, IEC 61508-2 and IEC 61508-4, for the nuclear application
sector. In this framework, IEC 60880, IEC 62138 and IEC 62566 correspond to IEC 61508-3
for the nuclear application sector. IEC 61513 and IEC 63046 refer to ISO as well as to
IAEA GS-R-3 and IAEA GS-G-3.1 and IAEA GS-G-3.5 for topics related to quality assurance
(QA). At level 2, regarding nuclear security, IEC 62645 is the entry document for the
IEC SC 45A security standards. It builds upon the valid high level principles and main
concepts of the generic security standards, in particular ISO/IEC 27001 and ISO/IEC 27002; it
adapts them and completes them to fit the nuclear context and coordinates with the
IEC 62443 series. At level 2, IEC 60964 is the entry document for the IEC SC 45A control
rooms standards and IEC 62342 is the entry document for the IEC SC 45A ageing
management standards.
NOTE 1 It is assumed that for the design of I&C systems in NPPs that implement conventional safety functions
(e.g. to address worker safety, asset protection, chemical hazards, process energy hazards) international or
national standards would be applied.
NOTE 2 IEC SC 45A domain was extended in 2013 to cover electrical systems. In 2014 and 2015 discussions
were held in IEC SC 45A to decide how and where general requirements for the design of electrical systems were
to be considered. IEC SC 45A experts recommended that an independent standard be developed at the same level
as IEC 61513 to establish general requirements for electrical systems. Project IEC 63046 is now launched to cover
this objective. When IEC 63046 is published this NOTE 2 of the introduction of IEC SC 45A standards will be
suppressed.

NUCLEAR POWER PLANTS – INSTRUMENTATION AND CONTROL
SYSTEMS IMPORTANT TO SAFETY – SELECTION
AND USE OF WIRELESS DEVICES



1 Scope
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.

• ISO Online browsing platform: available at http://www.iso.org/obp
3.1
authentication
provision of assurance that a claimed characteristic of an entity is correct
[SOURCE: ISO/IEC 27000:2018, 3.5]
3.2
category of an I&C function
one of three possible safety assignments (A, B, C) of I&C functions resulting from
considerations of the safety relevance of the function to be performed. An unclassified
assignment may be made if the function has no importance to safety.
Note 1 to entry: See also "class of an I&C system".
Note 2 to entry: IEC 61226 defines categories of I&C functions. To each category there corresponds a set of
requirements applicable on both the I&C function (concerning its specification, design, implementation, verification
and validation) and the whole chain of items which are necessary to implement the function (concerning the
properties and the related qualification) regardless of how these items are distributed in a number of
interconnected I&C systems. For more clarity, this document defines categories of I&C functions and classes of
I&C systems and establishes a relationship between the category of the function and the minimal required class for
the associated systems and equipment.
[SOURCE: IEC 61513:2011, 3.4]
3.3
class of an I&C system
one of three possible assignments (1, 2 or 3) of I&C systems important to safety resulting
from consideration of their requirement to implement I&C functions of different safety
importance. An unclassified assignment is made if the I&C system does not implement
functions important to safety.
Note 1 to entry: See also "category of an I&C function", "safety system".
