摘　　要：The paper discusses the structural design of a futuristic 700℃ MS(Molten salt)Storage Shell,which considers many elements in providing an adequate and comprehensive design.In designing the structural carbon steel for the tank,temperature is an important consideration because steel has a yield strength at 700℃,that is 33%of its nominal yield,while the Young’s Modulus at 700℃ is 50%of its nominal Young’s Modulus.At this temperature,thermal stresses can yield or tear the structural steel unless free expansion of the structure is allowed.This is accomplished with sand layers below each layer of steel and by including a small gap behind the side carbon steel layer.A roof shell design for the tank is also presented in this paper,comparing various roof shell types and their designs.All designs include thermal insulation and an inner stainless steel corrosion layer to protect the structural and thermal insulation elements of the tank from the MS.
