Application of MCAM in generating Monte Carlo model for ITER port limiter

On the basis of the pre-processing and conversion functions supplied by MCAM(Monte-Carlo Particle Transport Calculated Automatic Modeling System),this paper performed the generation of ITER Port Limiter MC(Monte-Carlo) calculation model from the CAD engineering model.The result was validated by using reverse function of MCAM and MCNP PLOT 2D cross-section drawing program.The successful application of MCAM to ITER Port Limiter demonstrates that MCAM is capable of dramatically increasing the efficiency and accuracy to generate MC calculation models from CAD engineering models with complex geometry comparing with the traditional manual modeling method.
