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

2015:43 Robust structural verification of pressurized nuclear components subjected to ratcheting
Background 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 deformation hardening, it may also exhibit material ratcheting. The combined effects of structural- and material ratcheting are not taken into account in the methods and material...

2014:21 Effects of additives on uranium dioxide fuel behavior
This report will form a basis for the reviews that SSM does when the license holders applies for use of nuclear fuel with additives. The report is also intended as a reference to the models that Quantum Technologies AB has developed. The report and the models will be a valuable source of information for SSM and other parties when discussing the performance of doped fuel. Ali Massih SSM...

2019:25 Maskulinitet, risk och säkerhet vid ett svenskt kärnkraftverk
SSM perspektiv Bakgrund Likt anställda vid ett järnverk, ett pappersbruk eller en oljeplattform omges även personalen vid ett kärnkraftverk av olika slags risker som hanteras genom ett mer eller mindre lyckosamt säkerhetsarbete. Kärnkraften är en högriskbransch och riskerna för de personer som arbetar inom den har inte enbart med reaktorn och den radioaktiva...

2019:29 Myndighetsstöd: Artificiell Intelligens – tillämpning inom kärnkraften
SSM perspektiv Bakgrund Området artificiell intelligens (AI) genomgår en omfattande utveckling och stora satsningar görs inom FoU på olika håll runt om i världen. Vinnova fick under 2017 i uppdrag av regeringen att genomföra en kartläggning och analys av hur väl artificiell intelligens (AI) och maskininlärning kommer till användning i svensk...

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 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...

2011:20 A Guidebook for Evaluating Organizations in the Nuclear Industry – an example of safety culture evaluation
Organizations in the nuclear industry need to maintain an overview on their vulnerabilities and strengths with respect to safety. Systematic periodical self- assessments are necessary to achieve this overview. This guidebook provides suggestions and examples to assist power companies but also external evaluators and regulators in carrying out organizational evaluations. Organizational...

2011:24 Utredning och kartläggning av tillfällen då människan räddat och förbättrat en situation där automatiken inte räckt till eller fungerat fel
ÅF har genomfört en litteraturstudie och beskrivit en aktuell bild över rådande automations-filosofier och på vilket sätt människan påverkas av olika nivåer av automation. De har även kartlagt och beskrivit tre händelser inom kärnkraftsindustrin där människan ingripit och räddat eller förbättrat en situation där...

2011:16 Modelling of ultrasonic testing of cracks in cladding
During the last two decades, SSM has supported research to develop a model for the non-destructive test situation based on ultrasonic technique. Such a model is important in many ways, for example to supplement and plan experimental studies and to perform parametric studies in qualification situation. Modeling can be a useful tool when the inspection system shall be technically justified.
