Measurement and Analysis of Neutron and Photon Flux Spectra in an ITER Shield Mockup with Open Channel and Cavity [PDF]

Journal of Nuclear Science and Technology, 2000
The neutron performance of the ITER shielding system has been experimentally investigated on the basis of an integral experiment for a shield mock-up with open streaming channel. The mock-up simulates the first wall, the shielding blanket, the vacuum vessel, the toroidal field coil and a radial channel through the shield blanket used for the mechanical
