The current "Moderator Booster" option only specify one material and radius. In practice, a moderator booster will contain additional layers to represent the hydride metal (YH2, ZrH2, etc.) and the envelope. Several layers may be required for high-accuracy representation.
For instance, we may need to represent the following:
- YH2 moderator 0.5-1cm radius
- gap: a few microns
- coating: a few 10s of microns
- liner (Nb for AMM technology)
- enveloppe: SiC, FeCrAl, TZM, SS, etc.
- gap: a few microns
It would be recommended to add option to define the "moderator booster"the same way TRISO are defined:
'Moderator Booster Materials': ['YH2', 'He', 'Cr', 'Nb', 'SiC', 'He'],
'Moderator Booster Radii': [0.5,0.001,0.002, 0.01, 0.05, 0.001], # cm
Please also advise how we can assign cost to the different elements (whether based on weight, or unit cost of the moderator booster).
