The Slovenian nuclear power plant, NPP Krško, is on track to exceed its planned electricity production of 5.453 billion kWh for 2024, ensuring stable operations while adhering to regulatory constraints. After securing approval for an operational extension until 2043, the plant is currently following a comprehensive action plan, slated for completion by the end of 2028.
NPP Krško’s management notes that extending the operational life of nuclear power plants beyond 60 years is becoming increasingly common. In the United States, for instance, eight nuclear plants have already received approval to operate for 80 years, with similar processes underway for other facilities. As a well-maintained plant with a focus on continuous improvements in nuclear safety, NPP Krško is a strong candidate for a potential life extension beyond 60 years.
To explore this possibility, NPP Krško will begin a feasibility study in 2025, aiming to evaluate the technical, financial, and risk factors involved in extending its operational lifespan. This study will provide insights into the requirements and measures needed to support such an extension.
Extending the plant’s operation beyond 60 years will involve a complex and lengthy administrative process, potentially spanning 10 years or more. This will require extensive analyses, including equipment replacement plans for components nearing the end of their operational life or those that can no longer be maintained. Furthermore, an independent expert review on radiological and nuclear safety, along with a new environmental permit and cross-border evaluations, will be required.
Given the extensive procedures involved, NPP Krško is taking proactive steps to ensure that it can secure the necessary permits and approvals for extending the plant’s operation well in advance, without delays.
