2. 1. Effects of Irradiation and Thermal Ageing on the Nanoscale Chemistry of Steel Welds

   Author : Kristina Lindgren; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; spinodal decomposition; thermal ageing; low alloy steel; reactor pressure vessel; irradiation damage; atom probe tomography; core barrel; clustering;

   Abstract : Structural materials of nuclear power plants degrade during operation due to thermal ageing and irradiation from the reactor core. Effects on the materials are an increase in hardness and tensile strength, and a decrease in ductility and fracture toughness, i. e. embrittlement. READ MORE

4. 2. Radiation Induced Precipitation in Reactor Pressure Vessel Steel Welds

   Author : Kristina Lindgren; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; precipitation; irradiation damage; low alloy steel; reactor pressure vessel; atom probe tomography;

   Abstract : Radiation induced clustering and precipitation affect the mechanical properties of the reactor pressure vessel (RPV) of a nuclear power plant, i.e. the material becomes embritteled. The combination of low Cu (0. READ MORE

5. 3. Simulation of radiation damage in Fe and Fe-Cr

   Author : Christina Lagerstedt; Jan Wallenius; Cristophe Domain; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

   Abstract : Steel is an important structural material in nuclear reactors used for example in pressure vessels and fast reactor cladding. In reactor environments it has been observed that ferritic steels are more resistant to swelling than the austenitic steels typically used. READ MORE
