Info

Management and Reactor Safety devision took over the responsibility for the German Support Programme coordination within Forschungszentrum Jülich. Since its establishment, the programme has comprised more than 150 tasks, providing research and development, training of IAEA staff, consultancy support, and the secondment of 17 cost-free experts to the IAEA. The achievements have been documented in almost 380 reports. Most of the technical developments have been implemented by the IAEA for routine inspection use. The European Atomic Energy Community (Euratom) started implementing safeguards instrumentation developed under the German Support Programme in a larger scale only after entering into force of the NPT Additional Protocol. In 2010, the German Support Programme consisted of 27 active tasks, among them the development of containment and surveillance systems (DCM-C5, EOSS), development of nuclear measurement methods and techniques (LIBS, DMCA, HM-5, Krypton-85 analysis), geophysical measurements for detecting undeclared activities, satellite imagery analysis ( Fig. 10) and the estimation of optimal inspection strategies by statistics and game theory.

3.8. Product Quality Control of Radioactive Waste & Packages Introduction Product Quality Control is the examination of radioactive waste to “verify the compliance of waste properties with the acceptance criteria of a repository” (DIN 25401-9). Already in the year 1985 the Product Quality Control Office for Radioactive Waste (PKS) has been installed at the Institute for Energy Research (IEK-6) on request of the German Federal Office for Radiation Protection (BfS). PKS advices and supports the BfS on the basis of §20 ATG (German atomic act) as an independent consulting expert group to verify the compliance of radioactive waste properties with repository relevant acceptance criteria. PKS renders expertise on technical methods for the conditioning and packaging of radiological waste and checks product quality control plans to be appropriate for the conditioning and disposal purposes. Moreover, PKS inspects reprocessing and conditioning plants, audits radwaste manufacturers and checks waste package inventory declarations and accompanying documentation prior to final disposal for the compliance with the required specifications and applicable relevant inventory limits. PKS also examines and assesses the methodological and analytical methods applied by the waste manufacturer. A large amount of PKS activities comprises the product quality control of radiological waste from the decommissioning of nuclear facilities, like phased-out nuclear power plants. The effect of product quality control contributes significantly to the safety of a nuclear waste repository. Hosting the Product Quality Control Office for radioactive waste in Germany at the institute IEK-6 underlines its position in the field of waste characterization and in the evaluation of the long-term safety properties of radioactive waste to be acceptable for a repository in Germany. PKS is organized two-fold: 1.) PKS-WAA is the sole group of experts authorized by BfS for the quality control of high- and medium-active nuclear waste from reprocessing facilities abroad (La Hague, France, and Sellafield, UK) and from the domestic high-level vitrification plant VEK of WAK Karlsruhe. 2.) PKS-I provides expertize for the BfS in the field of low- and medium-active German domestic waste from nuclear power plants, research institutions and Federal State Collecting Facilities to be characterized and prepared for final disposal. Basis for the quality control of waste & waste packages are the LAW / MAW Mine KONRAD waste acceptance criteria. This geological repository should be in operation in 2018. 20
