In the context of the life-extension program for the No. 3 unit of the Smolensk NPP, the life-exhausted RBMK-1000 control and protection system, the safety control systems of the power unit, and the analog-relay control apparatus of the technological equipment of the block control board (reactor and turbine departments) have been replaced with systems and software-hardware suites (SHS) developed by NIKIET. NIKIET has completed the full cycle of work from the structural development of the systems and SHS to implementation followed by follow-up support services. Based on experience in modernization of special RBMK CPS and SCS-T systems and the process control and protection systems of the technological equipment of reactor installations developed by NIKIET, a unique automated digital control system with a single multi-level and decentralized structure of a complex of technical means was created, which secures not only safe and reliable operation of the entire power unit but also the fulfillment of key requirements of the system. Currently, the fundamental solutions implemented in this system are used as standards for the development of automated monitoring and control systems for other facilities, specifically, reactor installations with fast reactors (BREST, MBIR).

在斯摩棱斯克核电厂 3 号机组延寿计划中，RBMK-1000 寿险控制与保护系统、动力装置安全控制系统、模拟继电器控制装置块控制板（反应堆和涡轮机部门）的技术设备已被 NIKIET 开发的系统和软件硬件套件 (SHS) 取代。NIKIET 已经完成了从系统和 SHS 的结构开发到实施以及后续支持服务的整个工作周期。基于 NIKIET 开发的专用 RBMK CPS 和 SCS-T 系统以及反应堆装置技术设备的过程控制和保护系统的现代化改造经验，形成了独特的自动化数字控制系统，技术手段复杂，结构单一，多层次分散，既保证了整个动力装置的安全可靠运行，又保证了系统关键要求的实现。目前，在该系统中实施的基本解决方案被用作为其他设施开发自动化监测和控制系统的标准，特别是带有快堆（BREST、MBIR）的反应堆装置。
