• 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 ... scientific council monitors the current research situation and provides the Authority with advice on the assessment of risks, authorization and optimization within the area. The council gives guidance when...

• 2015:04 DiD-PSA: Development of a Framework for Evaluation of the Defence-in-Depth with PSA

  interpretation of the definitions of Defence in Depth given by IAEA which outline a framework to meet PSA. For each level of defence and combinations of levels, methods to give estimates from a PSA perspective ... the discussion of the basic definitions and the basis for defence-in-depth, as defined by IAEA, leading to somewhat modified and further developed definitions that support the link to a developed PSA.

• 2015:38 Evaluation of fatigue in austenitic stainless steel pipe components

  Transferability of experimental results obtained for smooth test specimens under constant amplitude loading to realistic components subjected to variable amplitude loading is an important issue in the design ... design against fatigue. There is a lack of experimental fatigue data for austenitic steel components and the present study is an important contribution to fill this gap. Objective The present study is aimed...

• 2015:20 The effects of mild, acute hypoxia on cognitive performance

  Room air with reduced oxygen levels that prevent materials to ignite and combust is a cost-effective and increasingly popular fire prevention method. For system safety reasons, the effects of hypoxia, that ...  that is, the lack of sufficient oxygen (that is, less than 21% oxygen which is the approximate oxygen level of normal air), on cognitive performance of persons working under such conditions are important...

• 2015:11 Investigation of the Distribution of Phosphorus in Copper

  different amounts of phosphorus, 6 and 80 wtppm, respectively, have been investigated. The matrix of both alloys was analysed using atom probe tomography (APT). The matrix P concentration in the 80 wtppm P ... the bulk concentration and it was therefore concluded that the majority of the P atoms resides in the matrix. Grain boundaries in the alloy con- taining 80 wtppm P were investigated using transmission electron...

• 2015:43 Robust structural verification of pressurized nuclear components subjected to ratcheting

  Pressurized components in nuclear applications that are subjected to cyclic loading may exhibit progressive deformation, so called structural ratcheting. If the component is made out of a material that are ... ratcheting. The combined effects of structural- and material ratcheting are not taken into account in the methods and material models currently used for structural verification of pressurized nuclear components...

• 2015:07 TEM-lamella lift-out from the crack tip region of Alloy 600 for high resolution electron microscopy examination

  contributes to the development of a method for high-quality TEM lamella preparation from crack tip regions of nuclear materials. A standard compact tension (CT) specimen of Alloy 600 previously tested for ... corrosion crack growth in simulated PWR primary water was used to demonstrate the benefit of the proposed method. This report describes the procedure for cutting the CT specimen in order to access the crack...

• 2015:10 SafePhase: Safety culture challenges in design, construction, installation and commissioning phases of large nuclear power projects

  lifecycle phases of a nuclear power plant present new human-technology- organization challenges to regulators and licensees. Organizational processes and practices that have evolved in one phase of development ... definition of “good safety culture” in practice might be unclear. The objective of the SafePhase study is to improve the understanding of safety culture challenges facing regulators and power companies in different...

• 2015:50 Assessment of structures subject to concrete pathologies (ASCET)

  Nuclear Power Plants around the world are at the moment approaching, or in, their Long Term Operation stage of their operational phase. In addition, several NPPs have recently been carrying out uprate and life ... exchange of components important to safety, in order to extend their lifetime. As a result, ageing management has emerged as one of the main concerns of the nuclear community. The ASCET (Assessment of Nuclear...
