  • SSM Report 2008:01 A combined deterministic and probabilistic procedure for safety assessment of components with cracks – Handbook

    SSM has supported research work for the further development of a previously developed procedure/handbook (SKI Report 99:49) for assessment of detected cracks and tolerance for defect analysis. During the operative use of the handbook it was identified needs to update the deterministic part of the procedure and to introduce a new probabilistic flaw evaluation procedure. Another identified need...

  • 2008:47 Selected Models for Key Processes in a Nuclear Waste Repository

    The conceptual design of the disposal of spent nuclear fuel in Sweden is based on a multibarrier system. In the KBS-3 concept, the bentonite buffer is a barrier with the primary purpose of surrounding and protecting the canister. The bentonite buffer is expected to prevent or minimise the water exchange with the surrounding rock and protect the canister against mechanical damages caused by...

  • 2008:23 SKI’s and SSI’s review of SKB’s safety report SR-Can

    This report summarises the Swedish Nuclear Power Inspectorate’s (SKI) and the Swedish Radiation Protection Authority’s (SSI) joint review of the Swedish Nuclear Fuel & Waste Management Co’s (SKB) safety report SR-Can, on post-closure safety for a KBS-3 spent nuclear fuel repository at Forsmark and Laxemar respectively (SKB TR-06-09). As of 1 July 2008 the Swedish Radiation Safety...

  • 2008:29e Safety and Radiation Protection at Swedish Nuclear Power Plants 2007

    The safety level of the plants is maintained at an acceptable level. SKI has in its regulatory supervision not found any known deficiencies in the barriers which could result in release of radioactive substances in excess of the permitted levels. SKI considers that improvements have been implemented during the year in the management, control and following up of safety work at the plants. In...

  • 2008:38 Methodology for description and evaluation of cost profiles and cost structure during transitions period

    A demanding task for our generation is to assure the appropriate financial resources are invested in the Swedish Nuclear Waste Fund. This will enable future generations to execute the decommissioning and dismantling of nuclear power reactors and other nuclear facilities in a prudent manner. The main aim is to fulfil the demands of environmental and health codes in a pan-European context...

  • 2008:57 Discrete Feature Model (DFM) User Documentation

    This manual describes the DiscreteFeature Model (DFM) software package for modelling groundwater flow and solute transport in networks of discrete features. A discretefeature conceptual model represents fractures and other waterconducting features around a repository as discrete conductors surrounded by a rock matrix which is usually treated as impermeable. This approximation may be valid for...

  • 2008:50 Study on Developments in Accident Investigation Methods: A Survey of the “State-of-the-Art”

    The objective of this project was to survey the main accident investigation methods that have been developed since the early or mid-1990s. The motivation was the increasing frequency of accidents that defy explanations in simple terms, for instance cause-effect chains or “human error”. Whereas the complexity of socio-technical systems is steadily growing across all industrial domains,...

  • 2008:48E Review Statement and Evaluation of the Swedish Nuclear Fuel and Waste Management Co´s (SKB) RD&D Programme 2007

    The review of the RD&D Programmes (Research, Development, Demonstration) prepared by the Swedish Nuclear Fuel and Waste Management Co (SKB) is a recurrent task that the Swedish Nuclear Power Inspectorate (SKI) must carry out as a regulatory authority with the support of reviewing bodies of which the most important is the Swedish Radiation Protection Authority (SSI). The review statement for...

  • 2008:12 Recent Research on EMF and Health Risks. Fifth annual report from SSI’s Independent Expert Group on Electromagnetic Fields, 2007

    The report for 2007 is divided into four different frequency fields: static fields, extremely low frequency fields (ELF), intermediate fields (IF) and radiofrequency fields (RF). Recent volunteer studies have shown that movement in very strong static magnetic fields (>1T, used in magnetic resonance imaging) can induce electrical fields in the body and sensations of vertigo in some people and...

  • 2008:09 The Generalised Ecosystem Modelling Approach in radiological assessment

    An independent modelling capability is required by SSI in order to evaluate dose assessments carried out in Sweden by, amongst others, SKB. The main focus is the evaluation of the long-term radiological safety of radioactive waste repositories for both spent fuel and low-level radioactive waste. To meet the requirement for an independent modelling tool for use in biosphere dose assessments,...
