A complete cycle consisted of 16 hr of power opera- tion, with maximum and minimum NaK temperatures of 1275 and 1005OF, respectively, and 8 hr of isothermal operation at 1285OF. The rate of NaK temperature change during the transition from one condition to the other was approximately 7OF/sec, The heat exchanger log-mean temperature difference changed from O°F during isothermal operation to 74OF during power operation.
