“…The Japan Atomic Energy Agency (JAEA) has proposed the TBM design, which has a solid frame structure and solid breeder structure, taking into account manufacturability using the hot isostatic pressing (HIP) process, as shown in Fig. 1 [1][2][3]. In this design, the solid frame structure of the TBM comprises the FW and fabricated rectangular cooling channels.…”

“…Therefore, what type of level combination is used in an experiment should be taken into account. If any two columns are selected, nine possible combinations exist as a row: (1,1), (1,2), (1,3), (2,1), (2,2), (2,3), (3,1), (3,2), and (3,3). It can easily be proven that each combination appears exactly the same number of times as the number of rows.…”

The first wall of a fusion reactor blanket faces the core plasma directly. The first wall endures high heat loads that lead to high thermal stresses. To ensure the reliability of the first wall structure, it is desirable to reduce the thermal stress. In this study, structural optimization of the blanket first wall was carried out using the Taguchi method. The finite element method was used to conduct a numerical simulation to investigate the thermo-mechanical responses of the blanket first wall. The optimal configuration of the blanket first wall was derived.

“…The conducting plate is 0.01 m-thick copper. Each fin of the conducting plates has an important function to cancel harmful components of eddy current loops by superposition with the eddy current passing on to the neighboring fin [10]. The conducting plate is irradiated up to 5-10 dpa during 2-3 year operation.…”

“…In addition, the blanket must be robust against the electromagnetic forces acting on fast plasma disruptions with the current quench time of ∼0.03 s. Previously proposed 1.2 m × 1 m-sized blanket modules [5] are too large to survive to such disruptions. To sweep away this difficulty, the assembly of blanket modules with small cross section is being considered [16]. The module dimension in the toroidal direction is about 0.3 m and about 0.8 on the high field (∼11 T) and low field (∼4.2 T) side, respectively.…”
