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.

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 - 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 - 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.

This document:
• provides requirements and recommendations for the overall Electrical Power System. In
particular, it covers interruptible and uninterruptible Electrical Power Systems including
the systems supplying the I&C systems;
• is consistent and coherent with IEC 61513. Like IEC 61513, this document also highlights
the need for complete and precise requirements, derived from the plant safety goals.
Those requirements are prerequisites for generating the comprehensive requirements for
the overall Electrical Power System architecture, and for the electrical power supply subsystems;
• has to be considered in conjunction with and at the same level as IEC 61513. These two
standards provide a complete framework establishing general requirements for
instrumentation, control, and Electrical Power System for Nuclear Power Plants.
This document establishes:
• the high level specification and requirement to implement a suitable Electrical Power
System in a NPP that supports reactor systems important to safety. It also enables
electrical energy production providing the transmission grid with active and reactive power
and electro-mechanical inertia;
• the relationships between:
– the plant safety requirements and the architecture of the overall Electrical Power
System and its sub-systems (see Figure 1) including:
a) the contribution to the plant Defence in Depth;
b) the independency and redundancy provisions;
– the electrical requirements and the architecture of the Electrical Power System and its
sub-systems;
– the functional requirements and the architecture of the Electrical Power System and its
sub-systems;
– the requirements associated with the maintenance strategy and the architecture of the
Electrical Power System and its sub-systems;
• the design of Electrical power sub-systems (e.g. interruptible and uninterruptible);
• the requirements for supporting systems of Electrical Power System (HVAC, I&C, etc.);
• the Electrical Power System life-cycle framework.
This document does not cover the specification of:
• I&C systems;
• the transmission lines connecting to substations outside the NPP;
• electrical equipment requirements already defined in the industrial IEC standards;
• electrical power for security systems (e.g., fences, surveillance systems, entrance
control);
• lighting and socket facility.

Nuclear facilities - Equipment important to safety - Seismic qualification (IEC/IEEE 60980-344:2020)
EN IEC/IEEE 60980-344:2021

This International Standard describes methods for establishing seismic qualification procedures
that will yield quantitative data to demonstrate that the equipment can meet its performance
requirements. This document is applicable to electrical, mechanical, instrumentation and control
equipment/components that are used in nuclear facilities. This document provides methods and
documentation requirements for seismic qualification of equipment to verify the equipment’s
ability to perform its specified performance requirements during and/or after specified seismic
demands. This document does not specify seismic demand or performance requirements. Other
aspects, relating to quality assurance, selection of equipment, and design and modification of
systems, are not part of this document. As seismic qualification is only a part of equipment
qualification, this document is used in conjunction with IEC/IEEE 60780-323.
The seismic qualification demonstrates equipment’s ability to perform its safety function(s)
during and/or after the time it is subjected to the forces resulting from at least one safe shutdown
earthquake (SSE/S2). This ability is demonstrated by taking into account, prior to the SSE/S2,
the ageing of equipment and the postulated occurrences of a given number of lower intensity
operating basis earthquake (OBE/S1). Ageing phenomena to be considered, if specified in the
design specification, are those which could increase the vulnerability of equipment to vibrations
caused by an SSE/S2.

Nuclear power plants - Instrumentation and control systems important to safety - Development of HDL-programmed integrated circuits - Part 2: HDL-programmed integrated circuits for systems performing category B or C functions (IEC 62566-2:2020)
EN IEC 62566-2:2020

This part of IEC 62566 provides requirements for achieving highly reliable HDL-Programmed
Devices (HPDs), for use in I&C systems of nuclear power plants performing functions of safety
category B or C as defined by IEC 61226.
The programming of HPDs relies on Hardware Description Languages (HDL) and related
software tools. They are typically based on blank Field Programmable Gate Arrays (FPGAs) or
similar micro-electronic technologies such as Programmable Logic Devices (PLD), Complex
Programmable Logic Devices (CPLDs), etc. General purpose integrated circuits such as
microprocessors are not HPDs. Annex B.8 provides descriptions of a number of different types
of integrated circuits.
This document provides requirements on:
a) a dedicated HPD life-cycle addressing each phase of the development of HPDs, including
specification of requirements, design, implementation, integration and validation, as well as
verification activities associated with each phase,
b) planning and complementary activities such as modification and production,
c) selection of pre-developed components. This includes micro-electronic technologies and
Pre-Developed Blocks (PDBs),
d) tools used to design, implement and verify HPDs.
This document does not put requirements on the development of the micro-electronic
technologies, which are usually available as "commercial off-the-shelf" items and are not
developed under nuclear quality assurance standards. It addresses the developments made
with these micro-electronic technologies in an I&C project with HDLs and related tools.
This document provides guidance to avoid as far as possible latent faults remaining in HPDs,
and to reduce the susceptibility to single failures as well as to potential Common Cause Failures
(CCFs).
Reliability aspects related to environmental qualification and failures due to ageing or physical
degradation are not handled in this document. Other standards, especially IEC 60987,
IEC/IEEE 60780-323 and IEC 62342, address these topics.
This document does not cover cybersecurity for HDL aspects of I&C systems. IEC 62645
provides requirements for security programmes for I&C programmable digital systems.
This document provides guidance and requirements to produce verifiable HPD designs and
implementations requiring justification due for their role in carrying out category B or C safety
functions. This document describes the activities to develop HPDs, organized in the framework
of a dedicated life-cycle. It also describes activities and guidelines to be used in addition to the
requirements of IEC 61226 for system classification and IEC 61513 for system integration and
validation when HPDs are included.

Nuclear power plants - Instrumentation, control and electrical power systems - Requirements for electromagnetic compatibility testing (IEC 62003:2020)
EN IEC 62003:2020

IEC 62003:2020 establishes requirements for electromagnetic compatibility testing of instrumentation, control, and electrical equipment supplied for use in systems important to safety at nuclear power plants and other nuclear facilities. The document lists the applicable IEC standards (principally the IEC 61000 series) which define the general test methods, and provides the necessary application-specific parameters and criteria to ensure that nuclear safety requirements are met.
This second edition cancels and replaces the first edition published in 2009. This edition includes the following significant technical changes with respect to the previous edition:
a) title modified.
b) expand the scope to encompass Electromagnetic Magnetic Compatibility (EMC) considerations for electrical equipment.
c) provide guidance for addressing the use of wireless technology.
d) enhance the description of the electromagnetic environment to provide clarification when selecting custom test levels or for test exemptions.
e) include example information to be contained within an EMC test plan.
f) provide guidance for characterization of the electromagnetic environment at the point of installation within a nuclear facility.
