2013:12 Multivariatanalys av radioaktivitetsdata dels från utsläpp till luft och vatten från OKG och Clab dels i omgivningen av Oskarshamn
De svenska kärntekniska anläggningarna genomför regelbundet mätningar av utsläppt radioaktivitet till luft och vatten samt mätningar av radioaktivitet i olika provslag i omgivningen. Omgivningskontrollen genomförs enligt ett program framtaget av dåvarande Statens strålskyddsinstitut, nuvarande Strålsäkerhetsmyndigheten (SSM). Det nuvarande...

2010:21 Childhood leukaemia around nuclear facilities
The first indication of a possible relationship between living close to a nuclear installation and the risk of childhood leukaemia came from the United Kingdom in 1983. A cluster of childhood leukaemia in the town of Seascale which is located close to Sellafield was reported in a TV documen-tary. Since then almost 200 studies have been carried out in order to investi-gate the occurrence of...

2007:02e Radiation Environment in Sweden, summary
The radiation environment to which the population of Sweden is exposed is dominated by medical investigations and background radiation from the ground and building materials in our houses. That is the conclusion of the first general Swedish summary of environmental monitoring data and dose calculations within the field of radiation. The report shows that people’s behaviour in the form of...

2020:12 Assessment of the QT-COOL coolant channel module against the PBF RIA 1-2 experiment
SSM perspective Background The fuel rod analysis program SCANAIR has been developed by IRSN (Institut de Radioprotection et de Sûreté Nucléaire) for analysis of reactivity initiated accidents (RIA) in light water reactors. The Swedish Radiation Safety Authority (SSM) has access to SCANAIR in exchange for annual contributions for its further development. This ensures a possibility...

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...

2021:05 Cladding tube rupture under LOCA: Data and models for rupture opening size
SSM perspective Background The Swedish Radiation Safety Authority (SSM) follows the research on fuel performance closely. One aspect that is currently being studied in several research projects is the risk of release of fragmented fuel into the primary coolant in case of an accident. This risk depends on complex conditions were one is the possibility and size of a rupture of the fuel rod...

2021:07 Scenariourval i HFE-processen Arbetssätt och kriterier vid utvärdering av konstruktionens anpassning till människans förmåga
SSM perspektiv Bakgrund På en kärnteknisk anläggning genomförs under dess livstid så kallade anläggningsändringar i syfte att åtgärda identifierade brister, eller för att av andra skäl modernisera eller förbättra anläggningens konstruktion. Vid anläggningsändringar som påverkar arbetsuppgifter som har betydelse...
