2019:14 IAEA Safeguards: Staying Ahead of the Game
SSM perspective Background The Swedish Radiation Safety Authority (SSM) called for research proposals relating to non-proliferation. This call resulted in SSM accepting a proposal from the Vienna Center for Disarmament and Non-Proliferation (VCDNP) on “Improving IAEA Safeguards for Non-Proliferation and Disarmament: Assessing the Options for, and Feasibility of, Further Strengthening...

2013:09 An Application of the Functional Resonance Analysis Method (FRAM) to Risk Assessment of Organisational Change
The objective of this study was to demonstrate an alternative approach to risk assessment of organisational changes, based on the principles of resilience engineering. The approach in question was the Functional Resonance Analysis Method (FRAM). Whereas established approaches focus on risks coming from failure or malfunctioning of components, alone or in combination, resilience engineering...

2014:01 Cost Estimating for Decommissioning Nuclear Reactors in Sweden
In Sweden, decommissioning cost estimates are core inputs to the process of calculating licensee contributions to the Swedish national fund for radioactive waste management and decommissioning. Under the present system, the decommissioning cost estimates are produced by licensees every three years and formally submitted to the Swedish Radiation Safety Authority (SSM), which reviews the...

2014:27 Regulation applying to welding of pressure equipment – a comparative study
The PED was in force in November 1999 and has been mandatory in European Union Member States since May 2002. Most of the standards referred to in the PED are relatively new although some of the standards were adopted in the early 1990s. On the other hand, the ASME B&PV Code has been used for a long time now and is the result of several decades of industrial experiences. The authors present...

2012:03 The IAEA Integrated Regulatory Review Service Mission to Sweden in February 2012
The Swedish Government decided on January 22, 2009 to mandate the Swedish Radiation Safety Authority, SSM, to apply for an international review of the Author-ity and its areas of supervision, an ‘IRRS’ (Integrated Regulatory Review Service) carried out by the International Atomic Energy Agency (IAEA). On February 25, 2009, SSM made a formal request to the IAEA for an IRRS in Sweden. The time...

2015:09 PROSIR - Probabilistic Structural Integrity of a PWR Reactor Pressure Vessel
Following an OCDE round robin proposal, 16 participants from 9 countries (USA, Japan, Korea (6 participants), Sweden, Germany, Czech Republic, Spain, EC and France (3 participants)) have been involved in a round robin study called PROSIR, Probabilistic Structural Integrity of a PWR Reactor Pressure Vessel. The PROSIR project started already in 2003 and a final draft version of the main report...

2011:33 Mathematical modelling of ultrasonic testing of components with defects close to a non-planar surface
The report describes work that has been performed in order to model ultrasonic testing of components that contain a defect close to a non-planar surface. The studies have been performed in both 2D and 3D, and in 2D in both the anti-plane (SH) and the in-plane (P-SV). The results show that the presence of a non-planar back wall can reduce the detectability of defects close to the surface. The...

2016:26 Ensemble for deterministic sampling with positive weights
The aim of this project is to find a reliable method for determining an ensemble for Deterministic Sampling with only positive weights. This report is intended to work as a presentation of the project, as well as to work as a beginner’s guide to DS. In the report several methods for generating DS ensembles are presented, which can encode up to four moments and represent any kind of...

2010:10 Översikt av nationell och internationell kravbild avseende brandskydd på kärnkraftverk och hur dessa tillämpas i svensk kärnkraftindustri
De nationella föreskrifterna gällande säkerhet på kärnkraftsanläggningar har historiskt behandlat brandskydd på en mycket övergripande nivå och den gällande kravbilden i tillståndshavares SAR, STF, ledningssystem har utvecklats under lång tid men på ett divergerande sätt. Vissa tillståndshavare har valt att följa internationella...
