  This report is in partial fulfillment of deliverable D1.1 Optimization of the
SPI model and summarizes axisymmetric ITER SPI parameter scans performed by the
NIMROD code for several ITER equilibria. These axisymmetric parameter scans are
to assess the sensitivity of various injection parameters in preparation for 3D
MHD SPI simulations. The scans are comprised of 5 scenarios: S1 - fragment size
scan : 3 uniform pencil beam, 1 distributed size pencil beam S2 - velocity scan
: v = [250,500,750]m/s S3 - velocity dispersion scan : dv/v = [0.2,0.4] (linear
distribution) S4 - poloidal extent of plume : [15' ,45' ] (linear distribution)
(dv/v=0.2) S5 - poloidal injection angle : +/-[20' ,45' ] (dv/v=0.2) These
scans are performed with several ITER equilibria representative of the
operating range, from low current and thermal energy (H123 5MA, 29MJ Hydrogen
H-mode) to high current and high thermal energy (DT24 15MA, 370MJ D-T H-mode).
