Abstract : Heat transfer to Na at low Pe numbers, by M.S. Pirogov: Results are reported of tests on heat transfer to Na in a Cu tube over a range of Pe numbers from 17 to 416. The temperature of the Na inlet and outlet was measured by thermocouples. Special measurements revealed that the Te in the Na flow is uniform in these zones. The experimental conformed, with qualification, to the Martinelli-Lyons formula. Separation of Li isotopes in ordinary ion-exchange column, by G. M. Panchenkov, E. M. Kuznetsova, and L. L. Kozlov. Experimental and theroretical data are discussed. For a solution containing LiCl, Li3C6H5O7, LiC7H5O2, and LiOH filtered in an ion exchange column where sulfonated coal in hydrogenous form acted as the ion exchanger, the isotopic ratio of the samples were 13.3, 14.4, 14.1, and 14.2, respectively. The theoretical determination of the critical volume for solutions of different Li salts is discussed.
