Iter nuclear analysis strategy and requirements

The principle needs of ITER with regard to nuclear analysis can be divided into the broad categories of safety and licensing, plant operation, and decommissioning although there is much overlap and interdependence within these categories. 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 an ITER reference neutronics model, the application of a neutronics results database, and the management tools which will be required. Areas in which new codes and techniques need to be developed will be identified.
