2007:20 Internationellt samarbete inom OECD/NEA 2006 avseende nukleär kriticitetssäkerhet
Deltagande i internationellt samarbete inom OECD/NEA:s Nuclear Science Committee och dess Working Party on Nuclear Criticality Safety har fortsatt under 2006 med stöd av SKI. Inga stora projekt där jag varit mycket aktiv har pågått. Däremot har jag deltagit i arbetet genom granskning av förslag till slutrapporter, vid bedömning av nya projekt samt i fortsatt...

2007:23 On Safety Management, A Frame of Reference for Studies of Safety Management with Examples From Non-Nuclear Contexts of Relevance for Nuclear Safety
The authors present the theoretical framework. There they also discuss the pros of using the system perspective to build a useful frame of reference of safety management using non- nuclear organizations; this as a way to create models useful for the nuclear power industry but based on general understanding of the concept of safety management. The chosen organizations are used extensively to...

2007:33 Analys av mänsklig tillförlitlighet HRA-begreppets tillämpbarhet vid revisionsavställning
Analyser av mänsklig tillförlitlighet, Human Reliability Analysis (HRA) har använts under en längre tid i kärnkraftverkens probabilistiska säkerhetsanalyser. SKI har nyligen genomfört en utredning om befintliga metoder inom området HRA (litteraturstudie) och hur dessa metoder används av tillståndshavarna för de svenska kärnkraftverken...

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 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...

2007:05 Development of an Input Model to MELCOR 1.8.5 for Oskarshamn 3 BWR
An input model has been prepared for the Oskarshamn 3 rector. Demonstrations calculations, at current nominal operating conditions in Oskarshamn 3 for 3300 MW thermal power, were performed for three cases: (1) initial, steady-state conditions, (2) total loss of AC power and (3) large steam line LOCA. The results are presented in the report. 200 Lars Nilsson SKI English An input model has been...

1986:12 Chernobyl - its impact on Sweden
In case of a radiological emergency in Sweden, the Swedish National Institute of Radiation Protection (SSI) has the responsibility of organ1z1ng a special task force with experts both from SSI and from other authorities. Reports of increased radiation l evels reached SSI around 10 am on April 28, 1986, and the task force convened at 1030 am. A large number of measurements were made all over...

2010:22 Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods, Stage 16
This report constitutes Stage 16 of a long-term research and development program concerning the development of diagnostics and monitoring methods for nuclear reactors. Results up to Stage 15 were reported in SKI and SSM reports, as listed below and in the Summary. The results have also been published in international journals and have been included in both licentiate- and doctor’s degrees.

2010:45 Evaluation of models for cyclic plastic deformation – A literature study
Analysis of nuclear components subjected to cyclic plastic deformation is normally based on the American standard ASME III. With the focus to improve the modeling of the stress-strain response under non-monotonic loading, several models for the analysis of cyclic plastic deformation have been developed in recent years. However, experience shows that the analysis and evaluation of plastic...

2010:37 Utvärdering av regler och normer för betongkonstruktioner i svenska kärnkraftsanläggningar
Syftet med projektet var att ta fram rekommendationer för tillämpning av regelverk för betongkonstruktioner i svenska kärnkraftsanläggningar genom att jämföra och utvärdera dels relevanta krav utgivna av europeiska och nordamerikanska myndigheter, och dels relevanta normer och standarder, riktlinjer eller liknande för betongkonstruktioner. Baserat på...

2010:07 Indicators of safety culture – selection and utilization of leading safety performance indicators
Safety indicators play a role in providing information on organizational performance, motivating people to work on safety and increasing organizational potential for safety. The aim of this report is to provide an overview on leading safety indicators in the domain of nuclear safety. The report explains the distinction between lead and lag indicators and proposes a framework of three types of...
