2010:46 Development of the PRO-LOCA Probabilistic Fracture Mechanics Code, MERIT Final Report
The MERIT project has been an internationally financed program with the main purpose of developing probabilistic models for piping failure of nuclear components and to include these models in a probabilistic code named PRO-LOCA. The principal objective of the project has been to develop probabilistic models for piping failure of nuclear components and to include these models in a...

2018:17 Assessment of structures subject to concrete pathologies (ASCET), phase 2
Background ASCET is an international research project initiated by WGIAGE1 OECD2 / NEA3. WGIAGE4 Concrete subgroup is a working group within the OECD / NEA whose task is to address issues concerning the maintenance of the integrity of concrete structures, proposals for general principles to optimally handle the challenges of integrity, especially with regard to aging of concrete structures.

2009:15 Improvement and Validation of Weld Residual Stress Modelling Procedure
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 in order to arrive at proper conclusions when assessing detected flaws, for inspection planning and for assessment of leak-before-break margins. Therefore, it is very important to have...

2009:10 Regleringen av matarvattenflödet i en BWR. Med exempel från Forsmark 2
Säkerheten i kärntekniska anläggningar ska upprätthållas genom att radiologiska olyckor förebyggs. I reaktorer sker detta genom att det finns flerfaldiga barriärer och ett så kallat djupförsvar. I djupförsvaret ingår att åtgärder vidtas för att tillförsäkra lugn och störningsfri drift utan transienter som kan...

2009:26 Tillämpning av stabil spricktillväxt vid brottmekanisk bedömning av defekter i sega material
Vid brottmekaniska analyser studeras i huvudsak haverimekanismerna sprött brott och plastisk kollaps samt kombinationen av dessa. Den styrande mekanismen bestäms av komponentens materialegenskaper, styrande belastning och defektens geometri. Proceduren enligt SKI-rapport 99:49 är idag en av de mest använda metoderna vid brottmekaniska analyser. Proceduren som baseras på...

2009:27 Analysis Strategy for Fracture Assessment of Defects in Ductile Materials
SSM has supported research for investigating the role of secondary stresses when fracture assessments are performed for cracked structures made of ductile materials. There are evidences that indicate that some secondary stresses, such as weld residual stresses, are not as important as primary stresses for estimating the safety margin against rupture (measured by the J-integral) for the type...

2007:15 Evaluation of the FRAPTRAN -1.3 Computer Cod
The FRAPTRAN-1.3 computer code has been evaluated regarding its applicability, modelling capability, user friendliness, source code structure and supporting experimental database. The code is intended for thermo-mechanical analyses of light water reactor nuclear fuel rods under reactor power and coolant transients, such as overpower transients, reactivity initiated accidents (RIA),...
