EKONT-2: advancement of a demonstrator for dry–mechanical decontamination of corners and inner edges in nuclear facilitiesis a project to build a tool for the decontamination of corners and inner edges. The aim of this project is to investigate the performance parameters of the currently used devices and to find ways to improve them. For this purpose, several demonstrators have already been developed and tested in a test setup.

A mobile platform has been converted into a robotic system to place tools for the automatic decontamination and direct measurement of walls in nuclear power plants. This paper describes the required drive sizing, sensor integration, controller integration, and safety technology applied to the mobile platform to ensure that it is able to operate and place the tools in the correct positions without endangering humans in its vicinity.

The research project aims to separate abrasive and steel particles with the help of magnetic separation and wet sieving produced by waterjet abrasive suspension cutting. For this purpose, a prototype separation system with a magnetic filter has already been built and tested, which can separate up to 98 % of the steel particles from the mixture.

The recognition of the importance of managing safety led to the development of safety requirements that are now implemented by the International Atomic Energy Agency's member states. These include the need to develop training and education for managers with nuclear safety responsibilities, to develop a science-based training programme for future decommissioning project managers and to extend the impact of the project through on-site training for operators involved in these projects.

EMOS is a mobile inspection unit that remotely and automatically records the entire surface of the drum, including lid and bottom, optically, evaluates it analytically and both stores it electronically and outputs the results in the form of an inspection report. In this way, recurring inspections of the drum stock can be completed under the same inspection conditions each time.

At the Institute for Technology and Management in Construction (
KIT-TMB), the focus is on the development of an automated solution for the (clearance) measurement of near-surface contaminations. A mobile elevating working platform is used as robot platform with a contamination array as tool. The array measures the surface activity on the wall areas and verifies compliance with the thresholds. The contamination array is based on two sensor concepts: measurement and localization.

SHARE project intends to provide an inclusive roadmap for decommissioning research, in technical and non-technical areas, enabling stakeholders to jointly improve safety, reduce costs and minimise environmental impact in the decommissioning of nuclear facilities. It is based on a broad analysis of stakeholder needs including R&D, R&I, education, training, regulations, legislation, project management, costing and standardisation among others.

The PLEIADES project aims to develop digital twins (DTs) through a BIM (building information modeling) technology-based platform. To structure the data, PLEIADES proposes a decommissioning-oriented ontology that provides a common understanding of the concept, with specific decommissioning terminology. Among others, each simulation using a DT will consider a physical and radiological environment and estimate the waste produced, the waste management process, and the waste management cost.
