Abstract

Abstract

With the support of the modelling conversion platform cosVMPT, the 360° model is needed to solve this inaccuracy from asymmetry. The detailed structure of all main components for China Fusion Engineering Test Reactor (CFETR) has been developed. The whole model consists of Central Solenoid (CS), Vacuum Vessel (VV), Port (16 upper/lower ports, 6 equatorial ports in which 2 oblique are ones used for NBI beam channel), Thermal Shielding (VVTS & CTS), Toroidal and Poloidal Field Coils (TFC & PFC), Cryostat and the House Building. The water-cooled ceramic breeder (WCCB) blanket and water cooled divertor with full detailed structure is inserted, while spare ports are filled with shielding material. The preliminary calculation has been performed by MCNP code combining with the advanced “on-the-fly” GVR method, which was introduced to generate the global weight window to accelerate the neutron transport, and the reliable neutron and photon flux map was obtained. This work realizes the application of cosVMPT platform and OTF method in complicated fusion reactor, and it validates their robustness. In addition, the results of 360° model has been compared to that of sector model, to verify the validity and applicability of using sector model to simplify the modelling and calculation.
