• 2009:25 APRI-6 Accident Phenomenaof Risk Importance

  Kunskap om de fenomen som kan uppträda vid svåra haverier i en kärnkraftanläggning är viktig förutsättning för att kunna förutse anläggningens beteende, för att kunna utforma rutiner och instruktioner för haverihantering, för beredskapsplaneringen

• 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

• 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

• 2009:17 Effect of Welding Residual Stresses on Crack Opening Displacement and Crack-Tip Parameters

  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

• 2009:12 Evaluating safety-critical organizations – emphasis on the nuclear industry

  The regulator identified a few years ago a need for a better understanding of and a deeper knowledge on methods for evaluating safety critical organisations. There is a need for solid assessment methods in the process of management of organisational changes as well as in continuously performed

• 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
