THERMOMECHANICAL LAYOUT OF THE NET FIRST WALL ASSEMBLY
The FE computations are carried out for the water cooled version of the first wall structure and include plane, grooved and thin wall concepts respectively. For different wall support conditions and material parameters with inclusion of pressure loads in the ducts the computations are firstly done for the water coolant and then for helium coolant flow (after removing the liquid lead and the water coolant tubes from the ducts) respectively. There are alltogether 26 different cases investigated and documented. Here is the summary of the main results: + The first wall when mounted on the blanket, is subjected to high bending stresses. If it is not supported on the blanket, the stresses are mainly due to the wall's temperature variations and these are rather low within the plane wall width. + The rounded corners of the rectangular ducts are subjected to high stresses, especially for plane wall concept. + The martensitic steel appears to be a good engineering material.
