• 2022:08 Geophysical surveys on sub marine land- and rock slides and on alpine glaciers

  SSM perspective Background The future climate evolution and the impact it might have on a repository for radioactive waste is important when assessing the long-term safety. In a project funded by SSM (Holmlund ... wasting on the bottom of the deep trough through the Southern Quark were found. The genesis, timing and size of these deposits are important to resolve in order to assess their potential impact on nuclear...

• 2016:23 Technical Note, Modelling of the thermal evolution of the KBS-3 repository at Forsmark and associated induced seismic activity

  Phase Introduction The Swedish Radiation Safety Authority (SSM) reviews the Swedish Nuclear Fuel Company’s (SKB) applications under the Act on Nuclear Activities (SFS 1984:3) for the construction and operation ... encapsulation facility. As part of the review, SSM commissions consultants to carry out work in order to obtain information and provide expert opinions on specific scientific and technical issues. The results from...

• 2012:61 Geochemical Constraints on Buffer Pore Water Evolution and Implications for Erosion

  PCO2, SiO2(aq) and Na/Ca in groundwaters (and any future intruding glacial meltwaters) in the near-field at the site. This conclusion would not be evident from modelling approaches using mixing only. Modelling ... suggesting that the buffer may be partially altered prior to glacial meltwater intrusion. David Savage SSM English Mineralogical data from the Forsmark Site show that smectite and calcite occur at all depths...

• 2024:17 Atomistic studies on the adsorption and desorption of radionuclides on fuel crud and system surfaces in Light Water Reactors

  SSM perspective Background Radiation safety is of particular concern during power plant maintenance. Radionuclides produced by the neutron bombardment in the core during operation may accumulate on system ... filter system or piping and contribute to the radiation field. Some ions that are prone to neutron capture often become trapped in the deposits on the fuel cladding surfaces, also called CRUD. It is important...

• 2010:24 On Cost Estimate for Decommissioning of one Isotope Central

  sustainable and long term credibility of the Swedish financing system for nuclear waste liabilities. SSM conducts systematic examinations and reviews of the estimates submitted by the Swedish nuclear industry ... study for “bench-marking” purposes, in such cases when there is a need to supplement and correct field data from the industry. In the present study, data has been retrieved and organized such that the...

• 2019:27 Effect of residual stress on ductile fracture at low primary loads – Numerical study

  SSM perspective Background Present report is a continuation of earlier work reported in SSM2009:27 regarding an analysis strategy for fracture assessment of defects in ductile material and SSM2011:19 on ... on the influence from residual stresses on crack initiation and ductile crack growth at high primary loads. The Swedish procedure for safety assessment of components with defects is documented in a handbook...

• 2009:16 Influence of Hardening Model on Weld Residual Stress Distribution

  Weld residual stresses 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 of these events is important ... present report is the result of an effort to acquire and to develop the latest research results in the field of WRS and especially the influence of hardening model. The choice of hardening model has been the...

• 2017:22 Effect of weld repairs on residual stresses in nickel base dissimilar metal welds

  affect the residual stresses through e.g. increased tensile stresses and increased plastic straining on the surfaces of the piping in contact with the light water reactor environment. This may in turn reduce ... by numerical simulation with two dimensional axi-symmetric assumptions. Conclusions are drawn based on comparison of the weld residual stresses before and after weld repair. The results show that the inside...
