The thermophysical and mechanical properties of the copper heat sink material intended for use in ITER

Assessment of thermo-mechanical behavior in CLAM steel first wall structures

“…So, most heat loads of plasma heating and neutron heating are removed via heat sink layer. With SS316L as structural material, the maximum stress is at the interface of Be layer and CuCrZr layer, with the range of 140-180 MPa, which are within the allowable values of yield strength [10,11,14,16]. But, the reliability is difficult to evaluate because of residual stresses extremely difficult to predict at the joints.…”

“…During the past decade, researchers performed a considerable amount of work on the experimental tests and finite element (FEM) simulations to examine the performances of FW under heat flux and neutron with SS316LN as a structural material [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19]. Hatano et al [3] examined the integrity of the HIP bonded interface, fatigue life time, and fracture behavior of the panel.…”

Consolidation of HIP bonding technologies for the ITER first wall panels

“…These have the advantage of slightly superior mechanical properties and a higher resistance to cracking [3]. The main disadvantages are that the heat treatment must be integrated with the bonding processes and that care is needed to avoid a loss in properties due to excessive grain growth.…”

Direct measurement of neutral/ion beam power using thermocouple analysis

“…and the symbols are defined in Table 1 with values for constants appropriate to the MAST hypervapotrons [3].…”
