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 document(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.
IEEE Standards documents are developed within IEEE Societies and Standards Coordinating Committees of the
IEEE Standards Association (IEEE SA) Standards Board. IEEE develops its standards through a consensus
development process, approved by the American National Standards Institute, which brings together volunteers
representing varied viewpoints and interests to achieve the final product. Volunteers are not necessarily members
of IEEE and serve without compensation. While IEEE administers the process and establishes rules to promote
fairness in the consensus development process, IEEE does not independently evaluate, test, or verify the
accuracy of any of the information contained in its standards. Use of IEEE Standards documents is wholly
voluntary. IEEE documents are made available for use subject to important notices and legal disclaimers (see
https://standards.ieee.org/ipr/disclaimers.html for more information).
IEC collaborates closely with IEEE in accorda

Nuclear power plants - Instrumentation, control and electrical power systems important to safety - Categorization of functions and classification of systems (IEC 61226:2020)
EN IEC 61226:2021

This document establishes, for nuclear power plants2, a method of assignment of the
functions specified for the plant into categories according to their importance to safety.
Subsequent classification of the I&C and electrical power systems performing or supporting
these functions, based on the assigned category, then determines relevant design criteria.
The design criteria, when applied, ensure the achievement of each function in accordance to
its importance to safety. In this document, the criteria are those of functionality, reliability,
performance, environmental qualification (e.g. seismic) and quality assurance (QA).
This document is applicable to:
- the functions important to safety that are performed by I&C systems and supported by
electrical power systems (categorization of I&C functions),
- the I&C systems that enable those functions to be implemented (classification of I&C
systems),
- the electrical power systems that support those functions (classification of electrical power
systems).
The systems under consideration provide automated protection, closed or open loop control,
information to the operating staff, and electrical power supply to systems. These systems
keep the NPP conditions inside the safe operating envelope and provide automatic actions, or
enable manual actions, that prevent or mitigate accidents, or that prevent or minimize
radioactive releases to the site or wider environment. The I&C and electrical power systems
that fulfil these roles safeguard the health and safety of the NPP operators and the public.
This document follows the general principles given in IAEA Safety Requirement SSR-2/1 and
Safety Guides SSG-30, SSG-34 and SSG-39, and it defines a structured method of applying
the guidance contained in those codes and standards to the I&C and electrical power systems
that perform functions important to safety in a NPP. This document is read in association with
the IAEA guides together with IEC 61513 and IEC 63046 in implementing the requirements of
the IEC 61508 series. The overall classification scheme of structures, systems and
components for NPPs can be summarized as follows by Figure 1.

Nuclear power plants - Instrumentation and control important to safety - Electrical equipment condition monitoring methods - Part 6: Insulation resistance (IEC/IEEE 62582-6:2019)
EN IEC/IEEE 62582-6:2021

This part of IEC/IEEE 62582 contains methods for condition monitoring of organic and
polymeric materials in instrumentation and control cables using insulation resistance
measurements in the detail necessary to produce accurate and reproducible results during
simulated accident conditions. It includes the requirements for the measurement system and
measurement procedure, and the reporting of the measurement results.
NOTE Measurement of insulation resistance during simulated accident conditions with the aim of determining the
lowest value during the accident in order to assess cable performance involves special requirements given in this
document. Methods for measurement under stable (non-accident) conditions are available in other international
standards, e.g. IEC 62631-3-3.
The different parts of the IEC/IEEE 62582 series are measurement standards, primarily for
use in the management of ageing in initial qualification and after installation. IEC/IEEE 62582-
1 includes requirements for the application of the other parts of the IEC/IEEE 62582 series
and some elements which are common to all methods. Information on the role of condition
monitoring in qualification of equipment important to safety is found in IEC/IEEE 60780-323.

Nuclear power plants - Electrical power systems - Electrical power systems analysis (IEC 62855:2016)
EN IEC 62855:2021

IEC 62855 provides the electrotechnical engineering guidelines for analysis of AC and DC
electrical power systems in nuclear power plants (NPPs) in order to demonstrate that the
power sources and the distribution systems have the capability for safe operation and shut
down of the NPP, bringing it to a controlled state after an anticipated operational occurrence
or accident conditions and finally reaching a safe state.
The analytical studies discussed in this document provide assurance that the design bases
are satisfied to meet their functional requirements under the conditions produced by the
applicable design basis events. The studies provide assurance that the electrical power
system is capable of supporting safety functions during all required plant conditions.
NOTE The safety functions are described in IAEA Specific Safety Requirements SSR-2/1 related to the design of
the nuclear power plants..
Analytical studies validate the robustness and adequacy of design margins and demonstrate
the capability of electrical power systems to support plant operation for normal, abnormal,
degraded and accident conditions.
The analyses are used to verify that the electrical power system can withstand minor
disturbances and that the consequences of major disturbances or failures do not degrade the
capability of the electrical power systems to support safe shutdown of the plant and maintain
the plant in shutdown condition.
The analyses are performed with one or more of
• simulation tools (software and hardware) that have been verified and validated,
• hand calculations, and
• tests.
This document provides guidance on the types of analyses required to demonstrate that the
plant's auxiliary power system can perform the required safety functions. This document does
not provide specific details on how the analysis should be conducted.
This document does not cover digital controllers (such as controllers for rectifiers, inverters,
sequencers and electrical protection devices) used in electrical power systems. IEC 61513
gives recommendations that apply to the electronic controls and protective elements of the
electrical power systems.
This document does not include environmental conditions (i.e. temperature, humidity, etc.) or
external events (seismic, flooding, fire, high energy electromagnetic pulse, etc.) that may
impact equipment sizing or protection requirements. The external events lightning and
geomagnetic storms are included.
This document does not cover additional or unique requirements for stand-alone power
system, such as power supplies for security measures in NPPs. Pertinent clauses of this
document may be used as a guideline for such systems.
Redundancy in the power system design can increase the availability of electrical power to
critical plant equipment. Performing a probabilistic risk assessment (PRA) is a method of
assessing system availability and optimizing design for high reliability. This document does
not cover improving the reliability of NPP electrical power systems using statistical or diverse
and redundant schemes.
Requirements for safeguards of personnel involved with installation, maintenance and
operation of electrical systems and general personal safety are outside the scope of this
document. General guidance for lightning protection of equipment is provided in relevant
clauses of this document.
This document is intended to be used:
• for verification of the design of new nuclear power plants,
• for demonstrating the adequacy and impact of major modifications of electrical power
systems in operating nuclear power plants, and
• where there is a requirement to assess and establish operating limits and constraints for
existing plants.
Pertinent parts of this document can be used as guidance for decommissioning stages.

Nuclear power plants - Control rooms - Requirements for emergency response facilities (IEC 62954:2019)
EN IEC 62954:2021

This document presents the requirements for the on-site emergency response facilities
(referred to hereinafter as the “ERF”) which are to be used in case of incidents or accidents
occurring on the associated Nuclear Power Plant (NPP). The ERF consists of the Emergency
Response Centre (ERC), the Technical Support Centre (TSC) and the Operational Support
Centre (OSC), as shown in Figure 1.
It establishes requirements for the ERF features and ERF I&C equipment to:
• coordinate on-site operational efforts with respect to safety and radioprotection;
• optimize the design in terms of environment control, lighting, power supplies and access
control of the ERF;
• enhance the identification and resolution of potential conflicts between the traditional
operational means and emergency means (MCR/SCR and ERF, operating staff and
emergency teams, operational procedures and emergency procedures);
• aid the identification and the enhancement of the potential synergies between the
traditional operational means and emergency means.
This document is intended for application to new nuclear power plants whose conceptual
design is initiated after the publication of this document, but it may also be used for designing
and implementing ERF in existing nuclear power plants or in any other nuclear facility.
Detailed equipment design is outside the scope of this document.
This document does not define the situations (reactor plant conditions, hazards and
magnitudes of hazards) leading to mobilisation of emergency response teams and activation /
use of the ERF. These aspects are usually addressed in the NPP Emergency Plan. However,
the need for consistency of the ERF design and operation with the NPP Emergency Plan is
within scope.
