2. 1. Corrosion resistant alumina-forming alloys for lead-cooled reactors

   Author : Jesper Ejenstam; Inger Odnevall Wallinder; Il Soon Hwang; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

   Abstract : Generation IV nuclear power technologies provide attractive solutions to the common issues related to conventional nuclear power plants currently in operation worldwide. Through a significant reduction of the long-term radiotoxicity of nuclear waste, a more efficient use of nuclear fuel resources, and implementation of inherent safety features, Generation IV will make nuclear power sustainable and thus increase the public acceptance of nuclear power.

   Abstract : Concentrated solar power (CSP) is an interesting technology that involves storing solar energy in the form of heat and subsequently converting it into electricity. The third-generation (Gen3) CSP plants aim to operate at temperatures >700°C, necessitating the deployment of new heat storage materials that can withstand such high operating temperatures.

   Abstract : Liquid lead as heat transfer fluid presents attractive features for future power technologies, such as next-generation nuclear reactors, thermal solar power, and thermal storage. Liquid lead has excellent heat transfer properties well suited for operating at high temperatures. READ MORE

6. 4. High-temperature corrosion properties of chromia- and alumina-forming alloys

   Author : Tommy Sand; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-temperature corrosion; Alumina scale; Chromia scale; Cr-evaporation; Nitridation; Oxidation;

   Abstract : Electricity production, transportation, and manufacturing industry are some of the largest sources of greenhouse gas emissions. In many cases, these processes are carried out at high temperature and energy efficiency is limited by material degradation, so-called ‘high-temperature corrosion’. READ MORE

7. 5. Alloys in Contact with Molten Salts for Thermal Storage Applications

   Author : Esraa Hamdy Mohamedin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase transition; Molten salts; High-temperature corrosion; Alumina-forming alloys; Carburisation; Thermal energy storage TES ; Laves phase; Concentrated solar power CSP ;

   Abstract : The combination of a concentrated solar power (CSP) plant and a thermal energy storage (TES) system is a promising technology for power generation, in that it overcomes the challenges commonly faced by renewable energy systems, such as intermittency, dispatchability, and the gap between the energy supply and energy demand. The third generation (Gen3) CSP plants are designed to increase plant efficiency by using supercritical carbon dioxide (sCO2) instead of steam for the Brayton cycle gas turbines, requiring a minimum operating temperature of 750°C for the TES materials.
