Strength and Creep-Fatigue Analysis of a Molten-Salt Storage Tank

Molten chloride salt technology for next-generation CSP plants: Compatibility of Fe-based alloys with purified molten MgCl2-KCl-NaCl salt at 700 °C

“…The embrittle sigma phase precipitates at GBs, leading to the degradation of these steels' mechanical properties (especially anti-creep property) at high temperatures [56], indicating that the 700 °C seems not the optimum service temperature of SS 310. For the future application of chloride-TES tank, stainless steels with better thermal stability at >700 °C are required, which should have reasonably high-temperature mechanical properties, especially anti-creep properties [57].…”

Creep-fatigue damage analysis of a large horizontal molten-salt storage tank

“…A lot of researchers have spent their efforts to study the safety of high temperature equipment and components. By using finite element method, Zeng [1] carried out creep-fatigue assessment for a large non-anchoring vertical molten-salt storage tank in accordance with ASME-NH, and found that the creep damage of equipment was larger than the fatigue damage at high temperature. Dukare [2] performed creep-fatigue damage assessment of 2.25Cr-1Mo steel in a process reactor at high temperature according to ASME-NH Code Methodology.…”
