Materials for the High Temperature Reactor (HTR)

摘要

Selection and understanding of material behaviour is a vital part of the development of an advanced nuclear powerplant. For the High Temperature Reactor development program within Europe this issues is being investigated for the keycomponents of the reactor circuit through the support of the European Union Fifth Framework Programme. Material issuesare being addressed for the reactor vessel and certain high temperature regions including the turbine and the graphite core.This paper reviews the main elements of the work program and provides some initial findings with regard to material choicesand structural integrity needs.
