Abstract :
The cryopump concept for the ITER 2001 proposed by ITER-JCT was assessed. Some modifications were recommended. For these modified arrangements, Monte-Carlo calculations were performed to define the pumping probability of the cryopump together with the divertor duct. Results show that the ITER requirement can be fulfilled with small restraints if the pump inlet diameter is enlarged to 1000 mm and the neutron shield in the duct is taken out.
