Protective coatings for the hot gas duct tested were a NiCrAlY basis layer followed by a Y2O3 stabilized Zr02 layer. Other components which need to be especially designed are the isolation valves. Two different kinds have been investigated, axial-type and ball-type valves. Further tests before application are still necessary [41]. 

MATERIALS FOR NUCLEAR POWER PLANT AND PROCESS COMPONENTS 

Priority tasks have been the selection of high temperature, high strength alloys and testing of candidate commercial alloys. The material characteristics investigated included creep behavior, fatigue properties, structural stability, and corrosion resistance [32]. 

The characterization program for high-temperature alloys included the alloy types  

Creep rupture strength experiments have been conducted in the ZEMAK I - IV laboratory facilities in Julich. Fig. 2-15 shows some measurement results. Also fatigue tests with periodic stress - strain impact have been made to simulate load changes.

In the Westinghouse sulfuric acid hybrid cycle shown in Fig. 2-10 (see also appendix A.3.2.), HTGR heat will be used for the H2SO4 decomposition step. Both high-temperature and electric steps have been experimentally investigated at the Research Center Julich. The above hybrid cycle has undergone a detailed balance and cost analysis already in a plant design based on nuclear power [8].
