Following the success of the previous years work in modeling the divertor and pump duct of ITER, more 2-D variations of the geometry were introduced. These consisted of reducing the vertical height of the pump duct by 10% and 25%. These changes were folded in to the other geometrical variables. Results show that D/T recycling is basically uneffected by the reduced pump duct size. The He recycling is effected. Less helium is pumped as the pump duct is closed. The helium is still pumped more efficiently than the D/T, but the enhancement factor is reduced. Shifting the profile by 20 cm still produced more pumped helium, but this effect is also lessened as the duct is narrowed.
