Knowledge products delivered under the NDKM initiative

This document summarises the activities during the workshop on cutting methodologies applied to nuclear decommissioning, which took place at the EC Joint Research Centre (JRC) in Ispra, Italy, on March 24th and 25th, 2026.

This document provides a comprehensive overview of the operational procedures for managing Category 3 materials at the JRC-Ispra site. It details the lifecycle from identification and segregation to radiometric verification and disposal as conventional waste.

This document describes the waste acceptance criteria (WAC) applicable to radioactive and potentially radioactive materials routed to clearance from regulatory control and destined for reuse, recycling or disposal.

This document provides a comprehensive compilation of knowledge on the cutting methods and technologies most commonly employed in the nuclear industry for the segmentation of reactor internal components.

This document provides the end user with an overview of the established system and deployment thereof within State Enterprise Radioactive Waste (SERAW) for safe transport of radioactive materials, as well as the technical and human resources required to implement the activity. Thereafter, specific...

The State Enterprise Radioactive Waste (SERAW) provided a contribution to the Nuclear Decommissioning Knowledge Management Initiative by crafted an online mini-site which details an annual honey festival held on their premises. The mini-site presents the experience of SERAW in communicating with...

The document consolidates INPP’s practical experience from the first three VLLW burial campaigns at facility B19 and provides a reusable playbook for future campaigns. It captures the engineered barrier configuration, waste acceptance criteria, organisation and resourcing choices, quality and safety...

The implementation of a nuclear decommissioning programme requires building up a communication strategy with stakeholders and, among other, a continuous involvement of local population and authorities. This case study describes how JRC has tried a novel communication strategy through art by...

State Enterprise Radioactive Waste (SERAW) successfully decontaminated the primary circuit of units 1 to 4 at the Kozloduy Nuclear Power Plant (NPP) under Project 55-3: Decontamination of the Primary Circuits in Kozloduy NPP, Units 1 to 4. To execute the project, SERAW leveraged the same equipment...

​This document will provide the end user with an overview of the logistics of material coming from V1 NPP´s decommissioning. It will describe the main flows of materials and how they are processed or further used in recycling process. It will also present the necessary types of logistics and...

​This document will provide the end user with an overview of the transition group of tasks which have to be solved during the termination of operation of a nuclear power plant (NPP). The pre-decommissioning activities have been broken down in sets of activities which at times overlap.

The application of remotely operated equipment and robotic technologies are particularly relevant in high-radiation environments where minimizing personnel exposure is critical. The use of robotic cutting machines and remote control ensures precise cutting, segmentation, and safe extraction of...

This case study includes the description and results of a series of tests on different technologies and processes for incineration of radioactive waste conditioned into a bitumen matrix. These tests were performed in several incineration plants worldwide as part of a selection procedure for a...

This document will detail the experience gained and the lessons learnt from the design, authorisation, construction, operation, and maintenance of an interim storage facility (ISF) at JRC Ispra site´s nuclear facilities. This includes all the very low-level waste (VLLW) and low-level waste (LLW)...

This document will detail the process of successfully developing and authorising a prismatic container to collect solid low-level radioactive waste (LLW RAW) in a concrete matrix. The container is referred to as a final waste package (FWP) and it has been assessed through qualification calculations...

This product provides guidance for extracting, transporting, and storing VVER irradiated fuel in multipurpose dry cask storage.

This document describes the Project B1 for integrated fuel management, including intact, damaged, and experimental spent fuel assemblies. The process ensures the safe and efficient management of spent nuclear fuel, including its diverse states and meets high standards of safety and environmental...

This product conveys Spain's ENRESA's experience in repurposing the Turbine Building of the José Cabrera nuclear power plant into an Auxiliary Decommissioning Building (ADB). It describes the methodology, systems, and lessons learned collected in this project.

This document describes the experience of remotely controlled fragmentation of large, activated components of the V1 NPP primary circuits. It also describe lessons learned from the use of technical means and civil structures that were also used during the V1 NPP operation.
