Additional measurements were made of steam-void fraction, temperatures, and pressures in the KEWB capsule experiment. Analysis of data indicated that friction in the volume transducer piston was large during most of the transients. The dynamic piston friction was reduced to negligible magnitudes. A method for calculating the transient heat flux from the fuel disc was formulated. Boiling stability experiments were begun with a 2-ft-long rod bundle, consisting of a square array of 18 stainless-steel rods 0.25-in. dia, spaced on 0.312-in. centers. The rods are electrically heated in a natural-circulation loop, at one atmosphere pressure. A survey was began on theories and data on hydrodynamic instabilities in natural-circulation boiling systems. Preparation of apparatus for measurement of flow-void transfer functions in a SPERT IA channel was essentially completed. (M.C.G.)
