Preliminary analysis of neutronics performance for Chinese ITER HCSB-TBM

Neutronics performance analysis can provide database for the evaluations and systems design of ITER Test Blanket Module(TBM).In this paper,the neutronics performance of Helium Cooling Solid Breeder(HCSB)-TBM are calculated and analyzed.Firstly,neutronics calculations are performed using the Monte Carlo particle transport code MCNP/4C,and the Fusion Evaluated Nuclear Data Library(FENDL/2) offered by IAEA.The neutronics calculations include nuclear heating and tritium production rate.Then,inventory code EASY-2007 is used to perform the activation calculations of TBM.Activity and afterheat are presented and discussed in the paper.The results demonstrate that the current design can meet the enineering requirement from the neutronic point of view.
