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.
