More Information
Summary:The Chinese Fusion Engineering Tokamak Reactor （CFETR） is an important intermediate device between ITER and DEMO. The Water Cooled Ceramic Breeder （WCCB） blanket whose structural material is mainly made of Reduced Activation Ferritic/Martensitic （RAFM） steel, is one of the candidate conceptual blanket design. An analysis of ripple and error field induced by RAFM steel in WCCB is evaluated with the method of static magnetic analysis in the ANSYS code. Significant additional magnetic field is produced by blanket and it leads to an increased ripple field. Maximum ripple along the separatrix line reaches 0.53% which is higher than 0.5% of the acceptable design value. Simultaneously, one blanket module is taken out for heating purpose and the resulting error field is calculated to be seriously against the requirement.
