The operating conditions in fusion power reactors are extremely severe. Materials which can be exposed to neutron fluences of the order of magnitude of 200 dpa without drastic changes in their properties are not yet available. The existing alloys which are currently considered for further development do not comply with the conditions for low activation materials. Both conditions require development of new materials. In order to meet the present time schedule for the design and construction of a DEMO fusion reactor, a strategy is needed to: (i) organise development; (ii) derive irradiation data for high fluences by extrapolation from data obtained in existing facilities; (iii) decide which new facilities are necessary; (iv) assemble the data set required for the engineering design.
