“…These groups provide up to date CAD models of the regions of interest. The work presented here effectively extends earlier work [1] to report on additional nuclear analysis requested by the IO groups listed above. In particular, this work presents analysis for BMs on the outboard side of ITER.…”

“…This request was due to part of SB09 being directly exposed to the plasma and due to thin regions which may be difficult to get water cooling into place (see figure 1). The model used for this analysis was the same partially detailed 20 degree upper port model used in section 2.3 of reference [1] that was derived from the 40 degree BL-Lite model.…”

“…In earlier work [1], we showed that the design of BMs in the heating neutral beam (HNB) port 1 opening did not provide enough shielding to the VV/port extension to meet the 0.6 W/cm 3 VV heating limit. Note, there are 3 HNB ports in ITER and they are located in sector 02 and 03 at the equatorial mid-plane.…”

“…The basic approach we follow for nuclear analysis of a given BM has been described in earlier work [1] but for completeness, will be briefly described here again. A 3-D, "vacuum vessel inward", 40-degree global, partially simplified CAD model of the ITER machine was created from the latest detailed Catia based CAD files of ITER.…”

In the ITER design, the blanket modules (BM) provide thermal and nuclear shielding for the vacuum vessel (VV), magnets, and other components. We used the CAD based DAG-MCNP5 transport code to analyze detailed models inserted into a 40 degree partially homogenized ITER global model. The regions analyzed include BM09, BM16 near the heating neutral beam injection (HNB) region, BM11-13 near the upper ELM coil region, and BM18. For the BM16 HNB region, the VV nuclear heating behind the NB region exceeds the design limit by up to 80%. For the BM11-13 region, the nuclear heating of the VV exceeds the design limit by up to 45%. For BM18, the results show that He production does not meet the limit necessary for re-welding. The results presented in this work are being used by the ITER Organization Blanket and Tokamak Integration groups to modify the BM design in the cases where limits are exceeded.
