DEVELOPMENT TESTING AND PERFORMANCE EVALUATION OF LIQUID METAL AND MOLTEN SALT HEAT EXCHANGERS
Development testing was done on prototype, bifluid (molten salt- NaK) salt exchangers and on liquid-metal (NaKair) radiators in support of the ANP program. The molten salt was a Na-Zr-UF₄ mixture, and the NaK was 56 wt.% Na and 44 wt.% K Performance tests were conducted on prototypes of the main heat exchangers for the Aircraft Reactor Test. The flow range on the molten-salt side of the exchanger varied from Reynolds numbers of 1000 to 6000, and the NaK- flow operating range varied from Reynolds numbers of 15,000 to 200,000. Data were taken on 2025-, and 100-tube bundles at stant-up and after 500 and 1000 hr of operation No deterioration of the salt coefficient occurred wnvith time of operation. In general, the data were found to lie F Screening tes 40% below the Dittus-Boelter line in the Reynolds range of interest. The effects of tube spacer arrangements on the unit performance were investigated. Pressure-drop data are presented for 1.75- and 0.5-Mw Aircraft Reactor Test prototype radiator units. (C.J.G.)
