2012:02 Evaluation of activity build-up experiments
understand how the water chemistry affects the activity build-up on surfaces in different systems in Swedish nuclear power plants, which in turn provides information on conditions required to reduce the radiation ... about water chemistry conditions preferred to minimize the activity build-up. A number of experiments have previously been performed at Studsvik Nuclear AB. The effects on the activity build-up from iron, nickel...

2007:07 DECOVALEX-THMC Project - Task A
definition of the first phase, Task A-1, of the Task A of the international DECOVALEX project. The task is a working example of how interaction between THMC modelling and SA analysis could be performed. Starting ... Starting with the technical definition of the Task A, the report presents the results of preliminary THM calculations with a purpose of an initial appreciation of the phenomena and material properties that...

2008:07 Modelling of long term geochemical evolution and study of mechanical perturbation of bentonite buffer of a KBS-3 repository
(SKB) has recently completed a safety assessment project named SR-Can, related to the KBS-3 disposal concept. In this concept, the waste packages are surrounded by a buffer made of either MX-80 or Deponit CA-N ... study in support of SSI review of the SR-Can report. The purpose is to assess the geochemical evolution of both potential buffer materials due to the intrusion of different types of groundwater, with a similar...

2018:08 Calculated radiological consequences of applying European clearance levels to scrap metal from the decommissioning of Swedish nuclear facilities
generate materials with potential or known radioactive contamination. Clearance of materials means a decision that such materials can be released from regulatory control and used or disposed of without restrictions ... restrictions from a radiation protection point of view. According to regulations issued by the SSM, such decisions must be based on thorough measurements of the activity content and it must be shown that the...

2011:20 A Guidebook for Evaluating Organizations in the Nuclear Industry – an example of safety culture evaluation
Organizations in the nuclear industry need to maintain an overview on their vulnerabilities and strengths with respect to safety. Systematic periodical self- assessments are necessary to achieve this overview ... regulators in carrying out organizational evaluations. Organizational evaluation process is divided into five main steps. These are: planning the evaluation framework and the practicalities of the evaluation...

2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers
future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund et al. 2016), bathymetric ... as terrestrial data from a glacial morphological mapping campaign. A broad range of landforms could be observed in these data and the overall glacial morphology pointed towards a powerful glacial impact...

2010:25 Modelling Coupled Processes in the Evolution of Repository Engineered Barrier Systems using QPAC-EBS
Currently in Sweden, the SR-Site safety assessment for a spent nuclear fuel repository is being developed by the Swedish Nuclear Fuel and Waste Management Company (SKB). The planned SSM review of this work ... work requires access to a sufficient modelling capability to assess the combined performance of the engineered barriers (spent fuel canister, buffer and backfill) and the natural geosphere barrier. For the...

02:4 Qualification of Electrical Components in Nuclear Power Plants. Management of Ageing
finished and reported in Swedish in a limited publication 2000, Ingemansson Rapport H-14061-r-I. As the performed work was regarded to be of more general interest it is published again as a research report by ... by the Swedish Nuclear Power Inspectorate. To be used in the international cooperation in nuclear safety it was also translated into English by the inspectorate, which is this report. The republished Swedish...

2014:09 Further Development of the Core Simulator CORE SIM: Extension to coupled capabilities for BWRs
requires a set of input data from a commercial static core simulator. The driving perturbation can be specified both as a perturbation in thermo-hydraulic parameters or directly as a perturbation in macroscopic ... distribution of the noise in coolant density, pressure, enthalpy, inlet velocity, fuel temperature and neutron flux is obtained. In this work, some results of the noise simulations, performed for the case of a homogeneous...

2007:22 Safety Management An Introduction to a Frame of Reference Exemplified with Case Studies from Non-Nuclear Contexts
A systems perspective has been applied on safety management that will be the foundation for the frame of reference the authors intend to build during the three-year long project. The case studies are presented ... presented and form illustrations of both high quality safety management and weaknesses of the safety management and take a look at information feedback about the risks of the systems. An organizational perspective...
