Neutronics analysis for the test blanket modules proposed for EAST and ITER

Abstract

The dual-functional lithium lead-test blanket module (DFLL-TBM) system, which is designated to demonstrate the integrated technologies of both the He single coolant (SLL) blanket and the He-LiPb dual coolant (DLL) blanket, is proposed for testing in ITER to check and validate the feasibility of the Chinese LiPb blankets. Considering the conflict between the limited ITER resources for TBM testing and the requirement of various blanket concepts proposed by the parties, EAST, the superconducting tokamak being operated in China, can serve as a valuable pre-testing platform with some comparable design parameters to ITER for DFLL-TBM. In the contribution, neutronics calculations and activation of the TBMs in EAST are carried out and compared with those in the D–D and D–T phase of ITER. The results from EAST can make an analogy to ITER (to some extent).

ITER activities and fusion technology

“…Conversion programmes from the CAD data to the semialgebraic representation used by Monte Carlo codes such as MCNP have been developed by FZK [70] and IPP China [71]. These programmes have been applied to the CAD model of the 40 degree ITER torus sector consisting of all components relevant for the neutronic analyses.…”

CAD-based Monte Carlo automatic modeling method based on primitive solid

“…SuperMC/MCAM is the geometry and physics modeling part of SuperMC. Previous version SuperMC/MCAM 4.8 which modeling for MCNP was a mature and efficient modeling program which has been used widely Zheng et al, 2007;Huang et al, 2006;Lu et al, 2009).…”

Preliminary study on CAD-based method of characteristics for neutron transport calculation

“…MCAM has already been applied to many complex nuclear facilities successfully, including the International Thermonuclear Experimental Reactor (ITER) [19], the super-conducting tokamak EAST [20] being operated in China, the FDS series reactors design [21] and Compact Reversed Shear Tokamak Reactor (CREST) [22], etc.…”
