It is envisaged that ITER should produce as much as 700 MW of fusion power. This equates to the production of 2.4810 14MeV neutrons/s which will give an uncollided flux at the first wall of approximately 410 n/cm/s and a total with the addition of the collided to some 10 n/cm/s. ITER is therefore a significant nuclear facility and it is essential that an efficient and coherent strategy for nuclear analysis is in place. This paper reviews the status of the methods applied to date and recommends the future strategy which ITER should adopt to address the continuing requirements and responsibilities. This is done by consideration of the application of radiation transport codes, the creation of suitable models, developments in information technology, and the management tools which will be required. Areas in which new codes and techniques need to be developed will be identified.
