  • 2013:10s Kvalificering av elkomponenter i kärnkraftverk - Hantering av åldring

    Syftet med arbetet har varit att skapa ett underlag att användas vid planering av arbetet med miljökvalificering av framför allt komponenter i inneslutningen. Principerna är även tillämpbara utanför inneslutningen i områden som kommer att utsättas för ökad miljöpåkänning i samband med olika händelser. Rapporten är...

  • 2014:01 Cost Estimating for Decommissioning Nuclear Reactors in Sweden

    In Sweden, decommissioning cost estimates are core inputs to the process of calculating licensee contributions to the Swedish national fund for radioactive waste management and decommissioning. Under the present system, the decommissioning cost estimates are produced by licensees every three years and formally submitted to the Swedish Radiation Safety Authority (SSM), which reviews the...

  • 2014:27 Regulation applying to welding of pressure equipment – a comparative study

    The PED was in force in November 1999 and has been mandatory in European Union Member States since May 2002. Most of the standards referred to in the PED are relatively new although some of the standards were adopted in the early 1990s. On the other hand, the ASME B&PV Code has been used for a long time now and is the result of several decades of industrial experiences. The authors present...

  • 2014:52 Beständiga förändringar av säkerhetskulturen

    Projektet har genomförts dels som en litteraturstudie och dels som en intervjuserie vid svenska kärnkraftverk. Litteraturstudien resulterade i en beskrivning av viktiga komponenter inom området säkerhetskultur, faktorer som anses möjliggöra eller förhindra att en god säkerhetskultur uppnås samt metoder och arbetssätt för att utveckla och förbättra...

  • 2013:27 Numerical simulations of headed anchors break in reinforced and non-reinforced concrete structures

    The design codes for anchorage of equipment in concrete structures have been developed since the time the Swedish power plants were designed. Furthermore, the design basis has been updated and in some cases new mechanical loads have been added. As a consequence, it can be difficult for some anchorages to meet the requirements of today. In the design of anchorage equipment the beneficial effect...

  • 2014:28 Numerical simulation of ductile crack growth in residual stress fields

    The study has shown on the capability of the cell model in capturing the effects on ductile tearing from limited pre-load levels and a residual stress field. Some of the conclusions are as follows: No distinctive influence on the material fracture toughness is observed from pre-loading (work hardening), both tensile and compressive, at room temperature of 1.5 or 3 % total strain. The cell...

  • 2014:18 Evaluation of the Halden IFA-650 loss-of-coolant accident experiments 2, 3 and 4

    The analytical tools, which are fuel rod computer codes, that Quantum Technologies AB use and develop, contain models of several of the phenomena that are acting on the nuclear fuel (cladding temperature, fission gas driven pressure, strain and stress in the cladding, rod rupture, etc.) and how the separate effects interact in the complex integrated manner. The codes are under constant...

  • 2014:09 Further Development of the Core Simulator CORE SIM: Extension to coupled capabilities for BWRs

    The developed tool is fully MatLab based and requires a set of input data from a commercial static core simulator. The driving perturbation can be specified both as a perturbation in thermo-hydraulic parameters or directly as a perturbation in macroscopic cross-sections. As output, the 3-dimensional spatial distribution of the noise in coolant density, pressure, enthalpy, inlet velocity, fuel...
