Product Quality Control is the examination of radioactive waste to “verify the compliance of waste residue properties with the acceptance criteria of a
repository”. (DIN 25401-9)
• Develop a product quality control system, e.g. appropriate proof tools to check on radioactive waste properties & characteristics.
• Examine the long-term disposability of rad-waste residues from nuclear reprocessing (high-level vitrified waste containers)
• Process based product control: process qualification, inspections, documentation check.
• Overall & general tasks: method evaluation, advise (e.g. in politics). • Ever since 1985 PKS has been operating in the area of product
quality assurance of radioactive waste as a group of specialized experts on request of the German Federal Office for Radiation Protection (BfS).
Product quality control of radioactive waste

Nuclear safeguards
The IAEA and the German Government, represented by the Federal Ministry of Economics and Technology (BMWi), have agreed upon a Joint Programme on the Technical Development and Further Improvement of IAEA Safeguards in 1978.
IEK-6 coordinates the programme in close cooperation with the BMWi and works on nuclear measurement technologies, satellite imagery analysis and geoinformation systems.
The programme includes R&D tasks on measurement methods and techniques, safeguards data and information processing, containment and surveillance techniques, safeguards concepts for future technologies, and provides training of IAEA staff, consultancy support and the delegation of cost-free experts to the IAEA.
