Jedrske elektrarne - Nadzorne sobe - Uporaba video prikazovalnikov (VDU)

Ta mednarodni standard dopolnjuje standard IEC 60964. Predstavlja zahteve glede načrtovanja za uporabo video prikazovalnikov (VDU) v glavnih nadzornih sobah jedrskih elektrarn. Za glavno nadzorno sobo jedrske elektrarne standard IEC 60964 vključuje splošne zahteve za postavitev, potrebe uporabnika ter metode preverjanja in potrjevanja, pri čemer se ti vidiki v zadevnem standardu ne ponavljajo. Poleg tega standarda je treba prebrati tudi standarde IEC 61227, IEC 61771, IEC 62241 in IEC 61839. Ta standard je oblikovalcu v pomoč pri ugotavljanju načinov uporabe video prikazovalnikov (vključno z zasloni na individualnih delovnih postajah in večjimi zasloni za skupinsko delo ali gledanje z večje razdalje) skupaj s konvencionalnimi (ploščatimi) zasloni ali namesto njih z naslednjim: – navajanje načel za sklicevanje na zmogljivost video prikazovalnikov; – navajanje primerov dobre prakse in vodenje oblikovalca, da se preprečijo pomanjkljivosti. Ta standard vključuje: a) zahteve za potrebe po informacijah: – v skladu s cilji glede informacij, kot so delovanje, vzdrževanje, zaščita, – omogočanje dovolj velikega prostora, tj. lokacija, ureditev, – uporaba hierarhije in/ali razmerij, – preprečevanje nepotrebnih informacij, – zagotavljanje, da so informacije pomembne, b) zahteve za dobro predstavitev, kot so: – čist in neutripajoč zaslon z ustrezno frekvenco osveževanja, – dovolj velik zaslon in optimalna razporeditev, – ustrezna velikost in mere simbola, – slikovit zaslon s simboli poleg alfanumerične zmogljivosti, – standardizirani splošni simboli in imena, – razporeditev, usmerjena v potrebe človeškega dejavnika, npr. stereotipi glede prebivalstva, – uporaba metod za združevanje v skupine in šifriranje, – uporaba ustrezne smeri pretoka, – ustrezne ravni abstrakcije podatkov v skladu s potrebami različnih predvidenih uporabnikov, c) metode za enostaven in hiter dostop do specifičnih informacij trenutnega zanimanja: – z enostavno izbiro posameznih formatov ali zbirk formatov v skladu z informacijskimi cilji, – z uporabo različnih vrst menijev (ikone sorodnih informacij) ali drugih načinov dostopa (zadnji prikaz, izbira na zaslonu itd.) z vklopljenimi ali izklopljenimi zaslonskimi tipkami, zasloni video prikazovalnikov ali kazalniki, – z uporabo programirane predstavitve (sprožene z binarnim signalom, npr. alarmom), d) merila načrtovanja za dosego ustrezne zanesljivosti vseh funkcij, potrebnih za dosego opredeljenih informacijskih ciljev. Ta standard je namenjen uporabi pri načrtovanju novih glavnih nadzornih sob jedrskih elektrarn v skladu s standardom IEC 60964, pri čemer se to začne po objavi tega standarda. V primeru njegove uporabe v obstoječih načrtih nadzornih sob ali območij, je potrebna posebna pozornost, ker nekatere navedene predpostavke (npr. stopnja avtomatizacije) morda ne veljajo. Če je potreben odklon od tega standarda pri posodabljanju, je treba vzroke zabeležiti.

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
...

EN IEC 62855:2021(Main)
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.

Nuclear power plants - Instrumentation and control important to safety - Electrical equipment condition monitoring methods - Part 6: Insulation resistance
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.
