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...

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...

2007:26 Safety Culture Enhancement Project Final Report
At the International Conference on Safety Culture in Nuclear Installations, organized by IAEA in 2002, one concluding remark was that the regulators should encourage a sincere interest in safety culture among licensees. In line with this SKI wanted to explore a proactive path to encourage the licensees in their safety culture work. SKI also had the ambition to gain more information on the MTO...

2007:31e Safety and Radiation Protection at Swedish Nuclear Power Plants 2006
Safety related problems in the electric systems of the Forsmark 1 reactor were the dominant event in Swedish nuclear power plants in 2006. The incident has had a significant impact on our attitude towards the reliability of how safety systems function both in Sweden and abroad. In connection with SKI’s review of the incident it was found that the company’s management system was not...

2008:06 Synthetic Aperture Focusing Technique in Ultrasonic Inspection of Coarse Grained Materials
Experience from the ultrasonic inspection of nuclear power plants has shown that large focused transducers are relatively effective in suppressing grain (structure) noise. Operation of a large focused transducer can be thought of as an integration (coherent summation) of individual beams reflected from the target and received by individual points at the transducer surface. Synthetic aperture...

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,...
