The simple stellarator blanket module is largely reduced to calculating masses given on blanket and shield sizes as defined in the input file.
It also calculates neutron heat depositions based on the neutron decay length (this enters the cost function via shield pumping powers e.g.).
-Most of the blanket constraints implemented in tokamak PROCESS, namely `icc=52,53,54,55` are not available with `blktmodel = 0` and the KIT HCPB model, `blktmodel = 1` should be used instead.
