Abstract
One of the most severe problems for fusion reactors is the power load on the divertor target plates. In order to reduce the power load in the divertor radiation cooling by seeding of impurities is essential. Presently unseeded type-I ELMy H-modes appear not to offer a solution to those problems. Alternative operating scenarios with tolerable transient heat loads have to be developed. One of the potential alternative scenarios is the ELMy H-mode with impurity seeding. The paper summarises the work aimed at the reduction of the heat load to the target plates, both during, and inbetween ELMs, using the radiation of a purposely injected impurity. Two scenarios, the impurity seeded type-I ELMy H-mode and the impurity seeded type-III ELMy H-mode are compared. The ability of both scenarios to meet the integrated ITER requirements for Q=10 and acceptable target power loads is discussed in the paper.
