• 2013:04 Research and Development Program in Reactor Diagnostics and Monitoring with Neutron Noise Methods, Stage 18

  The program executed in Stage 18 consists of the following three parts: Application of CoreSim with a two-dimensional model of vibrating fuel assemblies, for the calculation of ex-core detector noise throughout a fuel cycle; An investigation of the neutron noise, induced by propagating perturbations, in various thermal and fast reactor systems, in two-group theory; A consistent derivation of...

• 2013:01 Validation of Weld Residual Stress Modeling in the NRC International Round Robin Study

  Weld residual stresses (WRS) 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 on weld residual stresses is important to make proper decisions when cracks in weld joints are detected. During the latest years, there has been a strong development in both analytical procedures to...

• 2013:31 Aesthetic ultrasound devices – current state of knowledge and suggested measurement set-up for characterization of exposure

  This report concerns the ultrasound devices used for the aesthetic purposes of body contouring and fat reduction (ablation of adipose tissue). Such devices have recently become more frequent on the Swedish market. These ultrasound devices are currently not medically regulated in Sweden and little is known about their safety and potentially harmful exposure when using them. This report aims to...

• 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...

• 2013:19 Eighth report from SSM:s Scientific Council on Electromagnetic Fields

  The Swedish Radiation Safety Authority`s (SSM) scientific council monitors the current research situation and gives the authority advice on the assessment of risks, authorization and optimization within the area. The council gives guidance when the authority shall give an opinion on policy matters when scientific testing is necessary. The council shall submit a written report on the current...

• 2013:14 Approaches used for Clearance of Lands from Nuclear Facilities among Several Countries – Evaluation for Regulatory Input

  SSM has recently established new regulations for clearance of materials, rooms, buildings and land (SSMFS 2011:2). The regulations specify that license holders for practices involving ionising radiation shall take measures after the cessation of the practice to achieve clearance of rooms, buildings and land. The regulations state nuclide specific clearance levels in becquerel per m2 for rooms...

• 2013:06 The sixth round of implementation according to PARCOM recommendation 91/4 – Report from Sweden

  According to the PARCOM Recommendation 91/4 contracting parties shall, in accordance with the guidelines annexed to this recommendation, every four years present a statement on progress made in applying best available technology (BAT) in order to minimise and, as appropriate, eliminate any pollution caused by radioactive discharges from all nuclear industries, including research reactors and...

• 2012:23e Integrated assessment of radiation safety in health and medical services

  The county councils do not meet the Swedish Radiation Safety Authority’s requirements in terms of radiation safety. This implies that their health and medical services have deficiencies in this area that could lead to serious consequences for patients and staff, a conclusion based on the Swedish Radiation Safety Authority’s compilation of information from the nine county councils that...

• 2013:20 Terrestrial Biosphere Modelling of C-14 Research

  The need to address radiological impacts from 14C released to the biosphere has been recognized for some time. However, because of its role in biological processes and its ecological cycling, the standard methods employed to model long-term radionuclide transport and accumulation in the biosphere cannot be used satisfactorily for 14C. In 2011, the Swedish Radiation Safety Authority (SSM)...

• 2013:34 Technical Note, Seismology – Post-glacial seismicity and paleoseismology at Forsmark

  Metoden som SKB använder för att förutse seismisk risk för slutförvaret skiljer sig i två avseenden från gängse förfarande. För det första, förkastningsrörelser inom förvaret är beräknade utifrån numeriska bergmekaniska modeller i stället för genom en Probabilistisk riskanalys för förkastningsrörelse...
