Emergency control room – remote shutdown at Krško
Slovenia
Following Slovenian nuclear regulations on nuclear power plant life extension—and in response to the Fukushima accident—the Slovenian Nuclear Safety Administration (SNSA) requested NEK to reassess its Severe Accident Management strategy. As a result, a new project was launched to enhance safety systems, including the installation of an emergency control room for remote shutdown.
The project covers engineering, design, procurement, and delivery of key components. It also includes technical site support during installation and commissioning. IDOM, in consortium with Tecnatom, is executing the project under an EPCC (Engineering, Procurement, Construction, and Commissioning) contract.
Importantly, the emergency control room will be located in a new bunker building at the Krško Nuclear Power Plant (NPP). This facility ensures operators can safely shut down the plant if the Main Control Room must be evacuated. The SNSA approved this upgrade as part of a broader modernization plan tied to a 20-year life extension for the plant.
Moreover, the project execution as well as design documentation is structured in three implementation phases. Each phase focuses on developing key equipment specifications, preparing design modification packages, and managing procurement and delivery of major components to the NEK site. Key systems include field instrumentation, transfer panels, I&C cabinets, nuclear instrumentation, the main emergency control board, and simulator panel replicas. All design work complies with strict nuclear safety and radiation protection standards.
This is the first project of its kind in Europe. Therefore, it positions IDOM to share its expertise with other PWR reactors across Europe and globally. As part of its long-term strategy, IDOM has also established a local presence by opening an office in Ljubljana.
