Local and the average heat transfer data were determined by passing liquid Na through a staggered pipe bundle by means of a closed, forced- circulation loop. The 0 content of the Na was reduced to 2.6 x 10/sup -3% by placing a cold trap in the system, and carrying out the tests under a protective Ar atmosphere. The amount of heat transferred was measured by means of an electrocalorimeter in the hydraulically stabilized portion of the system at Na temperatures between 200 and 350 deg C, at flow rates ranging from 0.1 to 2.0 m/ sec and Reynolds Nos. between 4700 and 90,000. It was found that in the rear portion of the pipe the heat transfer coefficient decreases smoothly. The peripheral heat transfer distribution showed a maximum, but the second maximum, usually observed when nonmetallic liquids are used, was not noted. Comparison with previously reported heat transfer data of Hg (C. Pickard et al., Trans. ASME 80: liquid metals; a similar agreement was found also with the theory developed by R. Cess and R. Crosh (Trans. ASME
