Description
Summary:The preliminary design of XRCS Survey spectrometer for ITER has been developed addressing many challenges snch as designing a ∼ 8.0 m long, vacuum extending sight-tube that interfaces crystal spectrometer, placed in the port-cell, with equatorial port-plug (EPP-11) while allowing ∼ 50 mm machine movements, and optimizing neutron shield design so that systems can fit into the available space and still the shutdown dose rates (SDDR) remains within the safe limits. The design detailing has been done for the sight-tube and its components addressing the ITER specific requirements. Engineering and neutronic analysis are performed tor estimating the thermal displacement, stresses in the front-end components, neutron flux on the sight-tube components, SDDRs in the interspace region etc.
