Innovative data handling, processing, fusion, and decision framework technologies used for assessing cemented waste package safety and maintenance strategies:Deliverable 7.7: Euratom project PREDIS

This work is a part of the European project, PREDIS, on pre-disposal treatment and management of low-level waste and intermediate-level waste, The state of the art report (D7.1) and the gap analysis (WP2) have identified the need for more research on adequate and industrially mature solutions (practices, data governance, technology, and tools) for monitoring the packages and supporting decisions in the preparation, handling, and long-term interim storage of low-level/intermediate-level cemented waste.In the frame of task 7.5, a data management framework was set up taking into account all information gained from read sensor data as well as processed and analysed data. These were collected and stored to enable and develop the decision-making process for cemented waste packages in pre-disposal storages. The work aimed to study and demonstrate data management practices, which help the end-users (waste, and data management organizations) to increase their organizational maturity. This was done by identifying the most relevant business processes and specifying possible technical enabler systems.The most relevant processes identified were the measurement process, system analysis process, information management process, and decision management process. Accompanying them, three enabler systems were specified, developed, and demonstrated for data platforms, and decision frameworks. System enablers were integrated into a data management framework, which manages integrated data from sensing to decision-making. This working report focuses on reporting the development work of the data platform, and the decision framework.This work is strongly connected to task 7.3 “Innovative integrity testing and monitoring techniques” (reported in D7.3) and task 7.4 “Digital twin” (reported in D7.5) which is on simulation and digital twins. <br/
