IEC 62954:2019

Nuclear power plants - Control rooms - Requirements for emergency response facilities

IEC 62954:2019 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).
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.

Centrales nucléaires de puissance - Salles de commande - Exigences pour les moyens de réaction d'urgence

l'IEC 62954:2019 expose les exigences pour les moyens de réaction d'urgence (ci-après dénommés "ERF") utilisées en cas d'incidents ou d'accidents qui surviennent sur la centrale nucléaire associée. L'ERF comprend l'ERC (Emergency Response Centre, centre de réaction d'urgence), le TSC (Technical Support Centre, centre de soutien technique) et l'OSC (Operational Support Centre, centre de soutien opérationnel).
Il établit les exigences pour les fonctionnalités de l'ERF ainsi que pour les équipements I&C de l'ERF pour:
· coordonner les efforts opérationnels sur site pour ce qui concerne la sûreté et la radioprotection;
· optimiser la conception en termes de contrôle environnemental, d'éclairages, d'alimentations électriques et de contrôle d'accès de l'ERF;
· améliorer l'identification et la résolution de conflits potentiels entre les moyens opérationnels traditionnels et les moyens d'urgence (MCR/SCR et ERF, personnel d'exploitation et équipes d'urgence, procédures opérationnelles et procédures d'urgence);
· faciliter l'identification et l'amélioration des synergies potentielles entre les moyens opérationnels traditionnels et les moyens d'urgence.

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 reaso
