Nuclear power plants - Control rooms - Supplementary control room for reactor shutdown without access to the main control room

Nuclear power plants - Control rooms - Supplementary control room for reactor shutdown without access to the main control room

IEC 60965:2016 establishes requirements for the Supplementary Control Room provided to enable the operating staff of nuclear power plants to shut down the reactor, where previously operating, and maintain the plant in a safe shut-down state in the event that control of the safety functions can no longer be exercised from the Main Control Room, due to unavailability of the Main Control Room or its facilities. The design has to ensure that the Supplementary Control Room is protected against the hazards, including any localised extreme hazards, leading to the unavailability of the Main Control Room. This new edition includes the following significant technical changes with respect to the previous edition: - requirements associated with regular testing of the supplementary control room (SCR); - requirements to assess the time available during which the reactor will be safe but unattended, in order to move from the main control room (MCR) to the SCR and for the SCR to become operational; - taking into account new requirements laid down by the IAEA.

Centrales nucléaires de puissance - Salles de commande - Salle de commande supplémentaire pour l’arrêt des réacteurs sans accès à la salle de commande principale

L'IEC 60965:2016 établit des exigences applicables à la salle de commande supplémentaire permettant au personnel d'exploitation des centrales nucléaires d'arrêter le réacteur, si celui-ci était en fonctionnement, et de maintenir l'installation dans un état d'arrêt sûr, pour le cas où les fonctions de sûreté ne pourraient plus être commandées de la salle de commande principale, en cas d'indisponibilité de celle-ci ou de ses équipements. La conception doit garantir que la salle de commande supplémentaire est protégée contre les risques, y compris les risques extrêmes locaux, entraînant l'indisponibilité de la salle de commande principale. Cette norme fournit aussi des exigences pour le choix des fonctions, la conception et l'organisation de l'interface homme-machine, ainsi que des procédures qui doivent être utilisées systématiquement pour vérifier et valider la conception fonctionnelle de la salle de commande supplémentaire. Les principales modifications techniques par rapport à l'édition précédente sont les suivantes: - exigences portant sur les essais classiques réalisés sur les SCS (salles de commande supplémentaires); - exigences permettant d'évaluer le temps disponible durant lequel le réacteur est en état sûr mais non surveillé, de façon à pouvoir se rendre de la SCP (salle de commande principale) à la SCS et à ce que la SCS devienne opérationnelle; - prise en compte de nouvelles exigences définies par l'AIEA.

Jedrske elektrarne - Nadzorne sobe - Dodatne nadzorne točke za prekinitev obratovanja reaktorja brez dostopa do glavne nadzorne sobe (IEC 60965:2016)

Ta mednarodni standard določa zahteve za dodatno nadzorno sobo, iz katere lahko operativno osebje jedrske elektrarne prekine obratovanje reaktorja in ohranja stanje njene varne zaustavitve, kadar nadzor varnostnih funkcij iz glavne nadzorne sobe ni več mogoč zaradi nerazpoložljivosti glavne nadzorne sobe ali njenih predelov. Dodatna nadzorna soba mora biti zasnovana tako, da zagotavlja zaščito pred nevarnostmi, vključno z morebitnimi lokaliziranimi izrednimi nevarnostmi, zaradi katerih glavna nadzorna soba ni razpoložljiva.
Standard določa tudi zahteve za izbiro funkcij, zasnove in ureditve vmesnika človek-stroj ter postopke, ki se morajo sistematično uporabljati za preverjanje in validacijo funkcionalne zasnove dodatne nadzorne sobe. Predvideva se, da se dodatna nadzorna soba, ki je na voljo za izvajanje postopkov zaustavitve zunaj glavne nadzorne sobe, v času običajnega obratovanja elektrarne ne uporablja, razen za namene rednega preskušanja. Zahteve odražajo uporabo načel človeškega inženiringa, saj se uporabljajo za vmesnik človek-stroj pri tovrstnem rednem preskušanju in neobičajnih pogojih v elektrarni.
Ta standard ne obravnava posebnih prostorov za odziv na izredne razmere (npr. center za tehnično podporo) ali prostorov, namenjenih za ravnanje z radioaktivnimi odpadki. Zunaj področja uporabe tega standarda je tudi podrobna zasnova opreme.
Ta standard upošteva načela posebnih varnostnih zahtev SSR-2/1 in varnostnih napotkov NS-G-1.3 Mednarodne agencije za atomsko energijo (IAEA).
Namen tega standarda je podajanje zahtev glede funkcionalne zasnove, ki se uporabljajo pri zasnovi dodatne nadzorne sobe jedrske elektrarne za izpolnitev varnostnih zahtev.
Ta standard je namenjen za uporabo za dodatno nadzorno sobo, katere konceptualna zasnova je vzpostavljena po izdaji tega standarda. Če ga želite uporabiti za obstoječe elektrarne ali zasnove, bodite še posebej previdni pri zagotavljanju dosledne podlage za zasnovo. To se navezuje na primer na dejavnike, kot je doslednost med dodatno nadzorno sobo in glavno nadzorno sobo, ergonomski vidik, stopnjo avtomatizacije in informacijsko tehnologijo, ter obseg sprememb za uvajanje v merilnih in nadzornih sistemih.

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 the

Nuclear power plants - Electrical power systems - Electrical power systems analysis
SIST 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
SIST 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.

SIST 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
SIST 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, control and electrical power systems - Requirements for electromagnetic compatibility testing
SIST 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.
