2009:16 Influence of Hardening Model on Weld Residual Stress Distribution
Weld residual stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important in order to arrive at proper conclusions when assessing detected flaws, for inspection planning and for assessment of leak-before-break margins. Therefore, it is very important to have...

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...

2008:30 A model for fission gas release from mixed oxide nuclear fuel
Nuclear fuel containing mixed oxide (MOX) pellets have been used since the 1960's. MOX fuel pellets are made from a mixture of uranium and plutonium oxide. MOX allows the large quantities of fissile isotopes produced and remaining in spent nuclear fuel from light water reactors to be recycled. Producing MOX fuel can be seen as a method to more efficiently use the natural uranium since...

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...

96:51 The Flooding Incident at the Ågesta Pressurized Heavy Water Nuclear Power Plant
This report is a Master's thesis in Nuclear Reactor Engineering to be submitted to the SKi (Swedish Nuclear Power Inspectorate). The work has been performed at the Division of Nuclear Power Safety, KTH,Stockholm. It is an independent investigation of the consequences of the flooding incident at the Agesta HPWR, in Stockholm, Sweden, which occurred on the 1st of May 1969. The issue was raised...

2015:19 Recent Research on EMF and Health Risk - Tenth report from SSM’s Scientific Council on Electromagnetic Fields, 2015
The objective of the report is to cover the previous year’s research in the area of electromagnetic fields (EMF). The report gives the Authority an overview and provides an important basis for risk assessment. The Swedish Radiation Safety Authority’s (SSM) scientific council monitors the current research situation and provides the Authority with advice on the assessment of risks,...

2013:30 Laser pointers and Eye injuries - An analysis of reported cases
The safety limits that exist for human exposure of laser radiation are essential to reduce the risk of injuries. These values, however, give very little information on what tissue damages that may be expected at various elevated exposure levels. Similarly, the Swedish Radiation Protection Authority (SSM) has very little information on how such tissue damage is related to the impairment of the...

2012:02 Evaluation of activity build-up experiments
This project aims to 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 exposure to power plant staff. The study was done to obtain knowledge about water chemistry conditions preferred to minimize the activity build-up. A number of...

2011:27 Riskanalyser inom extern strålbehandling
Strålsäkerhetsmyndigheten (SSM) arbetar pådrivande för att skydda människor och miljö från oönskade effekter av strålning. Inom sjukvård används strålning vid olika diagnostiska undersökningar och behandlingar. SSM verkar för att användningen av strålning inom sjukvård är säker för såväl...

2011:14 Rapport från SSM:s vetenskapliga råd om ultraviolett strålning 2010
Strålsäkerhetsmyndighetens vetenskapliga råd för UV-frågor ger myndigheten råd inom områden som rör sambandet mellan UV och biologiska effekter, vilket exempelvis har betydelse för förebyggande av hudcancer. Rådet ger också vägledning inför ställningstaganden i frågor där det krävs en vetenskaplig prövning...
