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.

IEC 62566-2:2020(Main)
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 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.
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.

IEC TR 63214:2019(Main)
Nuclear power plants - Control rooms - Human factors engineering

IEC TR 63214:2019 provides a summary of arguments and a technical basis for the development of a new Human Factors Engineering IEC standard and the alignment of IEC 60964. Based on the provided argumentation, the participating members will vote for such an approach. The proposed content of the new standard provides the basis for fruitful discussion within IEC SC 45A WG 8 and raises interest in the development of the new standard.
The scope of the new HFE IEC standard will follow a holistic approach towards the design of the plant-wide control rooms and all HMI, including e.g. the local control stations located throughout the plant. The general principle is to consider the complete nuclear installation design as a sociotechnical system, in a holistic and integrated way.

IEC 61225:2019(Main)
Nuclear power plants - Instrumentation, control and electrical power systems - Requirements for static uninterruptible DC and AC power supply systems

IEC 61225:2019 specifies the performance and the functional characteristics of the low voltage static uninterruptible power supply (SUPS) systems in a nuclear power plant and, for applicable parts, in general for nuclear facilities. An uninterruptible power supply is an electrical equipment which draws electrical energy from a source, stores it and maintains supply in a specified form by means inside the equipment to output terminals. A static uninterruptible power supply (SUPS) has no rotating parts to perform its functions.
This third edition cancels and replaces the second edition published in 2005. This edition includes the following significant technical changes with respect to the previous edition:
a) the principal objective of this edition is to address the requirements on the static uninterruptible power supplies in nuclear power plants;
b) in addition to Instrumentation and Control (I&C) power supplies include all static uninterruptible power supplies;
c) emphasize that the static uninterruptible power supplies shall protect the connected equipment (loads) from transients on the on-site AC distribution system (the immunity concept);
d) in accordance with the defence-in-depth concept, this standard applies to static uninterruptible power supplies for all equipment, not only for equipment important to safety, with a graded approach to verification and validation;
e) addition of the requirement that, when batteries are connected in parallel under abnormal operating conditions, they shall be properly protected with isolation devices to avoid any failure that may impair more than one division of the uninterruptible power supply.
