## 3 Nuclear Analyses
### Summary of the Nuclear Load's Spatial Distributions Analyses  
In this section, the main highlights of the analysis related to the assessment of the nuclear load's spatial distributions on the inner and outer target, both with WCLL and HCPB blanket, are outlined as follows:  
* The maximum and minimum values and their positions (in terms of row (R) and column (C) of the array) of nuclear heating (W/cm\({}^{3}\)), nuclear damage (dpa/FPY) and He-production (appm/FPY) on the main PFC elements (W-monoblocks, Cu/CuCrZr, Eurofer of PFC-CB supports) are well summarized in Table 6 (WCLL inner target), Table 7 (WCLL outer target), Table 8 (HCPB inner target) and Table 9 (HCPB outer target). * All these nuclear quantities show their maximum values generally located on the baffle region and external edges of the inner and outer target (both with WCLL and HCPB). This is since the baffle region has a higher view factor on the plasma than the straight leg of the vertical target: this entails a more intense neutron fluxes, especially
