Detection of Cm244 SF neutrons in electrorefiner with salt deck

models neutron flux in electrorefiner hot cell
eutectic salt included
model for electroreduced used fuel in metal form+LiCl-KCl eutectic salt
salt also contains 9 wt% UCl3 to kick start the electrorefining process
different batch sizes are modeled
composition U31.9-TRU0.4-NM0.2-RE0.5-Li0.2-K33.5-Cl33.3 wt%
alloy is a solid metal+salt cylinder
cathode that houses the electroreduced metal+salt is a carbon coated cylinder
carbon is a 5 cm thick closed cylinder
cathode/electroreduced alloy is 'housed' in 'equipment'
equipment is a 5 cm thick steel closed cylinder
hot cell has 'wall thickness' for later shielding calculations
shielding is 30 cm boron frits-baryte
vacuum must be last cell card
cells cannot overlap; these are red dotted lines on the VISED
