Description
The development of system code for CFETR (China Fusion Engineering Test Reactor) is in progress for the optimization of the CFETR design in both core physics and engineering. As one of the key modules, the neutronics interface module has been implemented within the engineering framework of CFETR system code. The neutronics interface module, which is designed to work in conjunction with the general neutronics codes, is constituted by three sub-modules at present: the Tokamak fusion neutron source modeling sub-module, the neutronics modeling sub-module and the post processing sub-module.
This work presents the parameter study on helium cooled ceramic breeder blanket neutronics with the neutronics interface module of the CFETR system code. The parameterized 3-D neutronic model of CFETR was set in the first place. Afterwards, the workflows of neutronic analyses were established. Several concerned geometric and material composition parameters of CFETR blanket were selected as arguments of certain ranges to pass the sensitivity analyses for target parameters (such as the tritium breeding ratio). And then, the workflows were abstracted as mathematical models and the so-called response surfaces for target parameters were established. Based on the workflow or the response surfaces, the fast estimation and optimization of target parameters could be achieved. Finally, an optimal set of parameters was proposed for CFETR helium cooled ceramic breeder blanket.
