• 2009:24 UV-radiation induced disease – roles of UVA and UVB

  There is a large uncertainty concerning the impact of UVA and UVB radiation on the skin and eye. For example, UVA radiation used to be considered low risk since it was believed that DNA damage could only be caused by UVB radiation. However, recent studies show that UVA and UVB can give rise to similar DNA damages in human skin. Because of the potentially greater exposure to UVA while using...

• 1999:13 Determination of the Neutron and Photon Dose Equivalent at Work Places in Nuclear Facilities of Sweden

  Various mixed neutron-photon fields at workplaccs in the containment of pressurised water reactors and in the vicinity of transport containers with spent fuel elements were investigated with spectrometers and dosimeters.The spectral neutron fluences evaluated from measurements with multisphere systems were recommended to be used for the calculation of dosimetric reference values for...

• 2023:09 Rapport från SSMs vetenskapliga råd om ultraviolett strålning 2022

  SSM perspektiv Bakgrund Strålsäkerhetsmyndighetens (SSM) vetenskapliga råd för UV-frågor bevakar det aktuella forsknings- och kunskapsläget vad gäller oönskade effekter av UV-strålning. Rådets arbete redovisas i en rapport årligen. Rådets arbete ger myndigheten stöd för bedömning av hälsorisker och åtgärder...

• 2025:01 Safety Concept Evaluation with Failure Tolerance Analysis

  SSM perspektiv Bakgrund Hög funktionssäkerhet uppnås genom att använda redundans. Redundanser (enkelfelstålighet) blir i sin tur effektiva genom att tillämpa ytterligare konstruktionsprinciper såsom fysisk och funktionell separation och diversifiering. Tillståndshavare av kärnkraftsreaktorer måste visa att krav uppfylls, inklusive kraven på...

• 2020:07 Fibre Clogging in Nuclear Power Plants

  SSM perspective Background Emergency core cooling systems in boiling- and pressurized water reactors use strainers. Their purpose is to out foreign material suspended in the cooling water so this material does not reach the reactor. After the 1992 event at Barsebäck nuclear power plant when the strainers of the emergency cooling system was clogged due to fibers in the cooling water, all...

• 2021:01 In situ NMR condition monitoring of cable insulations in Nuclear Power Plants

  SSM perspective Background As the nuclear power plants are ageing, it is important to verify that every component installed can function safely in the intended environment. Cables are among the most common components in a nuclear power plant and are required to function during normal operation as well as in the event of an accident. There is a need within the nuclear industry for...

• 2021:02 On Water Induced Sensitization of Ni (Fe,Cr) alloys towards Stress Corrosion Cracking in LWR Piping from 1st Principles Modelling

  SSM perspective Background In Swedish Light Water Reactors (LWR), stress corrosion cracking of reactor components and welds occurs from time to time. As the nuclear power plants are ageing, it is essential to study and further understand the mechanism for environmentally induced sensitization. Natural cracking is a phenomenon that is difficult to predict and very hard to study since it occurs...
