• 2021:14 Reliability, Feasibility and Significance of Measurements of Conductivity and Transmissivity of the Rock Mass for the Understanding of the Evolution of a Repository of Radioactive Waste

  SSM perspective Background The conducted research was part of the international research project DECOVALEX 2019 (DEvelopment of COupled models and their VALidation against EXperiments). DECOVALEX 2019 consisted of seven different research projects called Task A to G. SSM were involved in Task G, which were composed of three different teams from Technical University of Liberec (TUL), Seoul...

• Poddavsnitt 19: Spåren efter Tjernobyl - 35 år efter olyckan

  Den 27 april 1986 larmade mätutrustning vid kärnkraftverket i Forsmark. Först trodde personalen att utsläppen kom från någon av deras reaktorer och man evakuerade anläggningen, men ganska snart stod det klart att reaktorerna i Forsmark var intakta. Att utsläppen kom utifrån via vindar österifrån. Det var reaktor 4 i Tjernobyl i dåvarande...

• 2021:09 Mechanisms important for material modelling in weld residual stress analysis

  SSM perspective Background The prediction of weld residual stresses (WRS) is very complex as many mechanisms and phenomena influence the development of WRS during welding. For accurate prediction, the constitutive material models used are essential and must be able to describe the material response of the weldment constituents. For example, selection of a material model should only depend on...

• 2021:10 Establishment and use of attention values in environmental fatigue assessments

  SSM perspective Background As Swedish NPPs reach their original technical design life, re-assessment of the fatigue life of structural components is needed for safe long term operation (LTO). In these re-assessments one must consider that new knowledge has shown that environmental effects on fatigue life must be considered. One common method to verify the fatigue life of structural components...

• 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...

• 2021:06 Quality Assurance Review of the Swedish Nuclear Fuel and Waste Management Company’s LOT Experiment (Phase S2 and A3) at the Äspö Facility in Sweden

  SSM perspective Background This report presents a quality assurance (QA) review of the work done by SKB to retrieve the S2 and A3 parcels from the Long term test of buffer material (the LOT experiment) at the Äspö Hard Rock Laboratory. Each LOT parcel comprises a heated copper tube surrounded by bentonite, with a number of copper coupons and various other test and monitoring instruments...

  Strålsäkerhetsmyndighetens forskningsmedel fördelas via utlysningar

  Strålsäkerhetsmyndigheten (SSM) ändrar sina rutiner när det gäller forskningsfinansiering och fördelar från och med 2021 huvuddelen av forskningsmedlen via utlysningar. Förändringen utgår från myndighetens nya policy för forskningsfinansiering och är ett led i att öka transparensen för myndighetens forskningsprocess.
