Synopsis : Alloying design and manufacturing results of "Cask Forging" to transport nuclear reactor spent fuel are described. As a result of investigating chemical composition to satisfy appropriate properties such as TS 45 kgf/mm2 and Tndt -40 through the 300 mm wall thickness of a dry-type TN 12/12 cask, 0.1%C-1.2%Mn-1.5%Ni steel was developed. Forging products, based on this alloy design and adoption of 100 t ingots by using our newly developed "Hollow Ingot Technique," showed sufficient mechanical properties as desired. The product was acceptable for materials specified by K1R curve in ASME Code. Other alloying steels can be produced: Ni-less 2% Mn steel for alternative use, and low C-1.3%Mn-2.25%Ni steel for arctic service. |
