Abstract

The successful development of nuclear process heat depends critically on the evaluation, qualification and development of metallic materials for components operating at the highest temperatures within the primary and secondary circuits. Although the main topics of this specialist meeting are the concepts and the design of the components, one major problem for the construction of the plant is the availability of specified alloys for use at high temperatures, especially in view of the fact that established design rules and accepted codes are available only for temperatures up to about 800oC. In the FRG, therefore, an extensive materials evaluation and development programme is underway. In addition to the principal project partners, the steel and tube-making companies, several research institutions in Germany and the successor of the Dragon-Project metals group, HTMP, are involved in this programme.
