Smarter waste strategies: Helping deliver on the promise of advanced nuclear
At COP28, held in Dubai in 2023, a clear consensus emerged: Nuclear energy must be a cornerstone of the global clean energy transition. With electricity demand projected to soar as we decarbonize not just power but also industry, transport, and heat, the case for new nuclear is compelling. More than 20 countries committed to tripling global nuclear capacity by 2050. In the United States alone, the Department of Energy forecasts that the country’s current nuclear capacity could more than triple, adding 200 GW of new nuclear to the existing 95 GW by mid-century.

Technical Specifications are intended to ensure that nuclear power plants operate within the hypotheses for safety analysis and within the limits calculated from these analyses. It is only through strict adherence to them that it is guaranteed the plant safety operation and that design parameters are maintained as specified in the Safety Study. To this end, it is needed to comply with the Limiting Conditions for Operation (LCO), to implement the Surveillance Requirements within the specified frequency and to execute required actions within the time period if needed. Tecnatom has designed and developed a digital tool for online monitoring of Technical Specifications. It enables surveillance requirements planning, identifying their status and the time available for its implementation providing the user information to update their planning. The application compares continuously current plant status with the Technical Specifications. Each time a Limiting Condition for Operation is surpassed, the user will receive an alert and will count on a friendly interface to follow-up the required actions in a paper-based or flowchart view. The user interface shows the actions that are being executed and their remaining time. This digital tool facilitates Technical Specifications monitoring and compliance contributing to safe and reliable plant operation. Functionalities such as integration with digital plant monitoring or control systems, interactive representation of LCO, alerts and actions execution reports provide significant advantages compared with traditional follow-up based on paper documents reducing human errors and optimizing the planning. This system greatly reduces the chances for failing to meet the surveillance requirements and therefore the number of reportable events. It also contributes to better reaction by the operator in the event of non-compliance. It is also a powerful tool to support during operation modes transitions as it verifies the plant status complies with all the LCO in the current mode and those needed to change the operation mode.
