Two 500-kw fused-fluoride-to-NaK heat exchangers, two 500-kw NaK-to-air radiators, and a 20-tube highvelocity heat exchanger were fabricated for a heatexchanger development program. A construction procedure, utilizing both inert-arc-welding and hightemperature dry-hydrogen brazing, was used successfully on all of the units. The tube-to-header joints were welded and back-brazed; the manifold joints were inertarc-welded with full penetration; and the tube-to-fin joints were brazed. A detailed description of the fabrication of each type of component is discussed and a cost analysis of the 500-kw units is presented. (auth)
