2025:01 Safety Concept Evaluation with Failure Tolerance Analysis
Bakgrund Hög funktionssäkerhet uppnås genom att använda redundans. Redundanser (enkelfelstålighet) blir i sin tur effektiva genom att tillämpa ytterligare konstruktionsprinciper såsom fysisk och funktionell ... separation och diversifiering tillämpas i tillräcklig utsträckning. Sedan 2013 har den finska myndigheten STUK ställt specifika krav på så kallade feltoleransanalyser (FTA). I Sverige finns för närvarande inga...

2003:33 Characterization of the Microstructure in Recrystallized Zircaloy-2 Cladding Irradiated to a High Neutron Dose
Bakgrund Då bränslestavarna bränns ut i härden på kärnkraftsreaktorerna utsätts stavarnas kapslingsmaterial för en neutronbestrålning som leder till stora förändringar i materialet. Materialet hårdnar samtidigt ... samtidigt som det blir mindre tåligt för att deformeras. De små så kallade sekundärfaspartiklar som finns i materialet och som anses ha stor betydelse för materialets korrosionsegenskaper amorfiseras och börjar...

If a reliable leak ... detection system is implemented in a pipe system, the only way a break can occur is if the stress state (i.e. system loads and weld residual stresses) are distributed in a way that an initiated circumferential...
