DEVELOPMENT OF HYDRAULIC BALL (HY-BALL) CONTROL SYSTEM. Quarterly Progress Report No. 3, January-March 1963

Technical Report ·
OSTI ID:4717510
Physics analyses of power distributions for the Hy-Ball controlled core were continued. Axial power distributions were computed for a two-zone fuel- enrichment scheme and also for a single-zone poison scheme; the computations included all effects with the exception of changes due to fuel burnup and variations in void distribution. Computations for determining radial power distributions begun previously were completed. The pre-test analytical studies of the effects on Hy-Ball column operation due to steam formation within the control system were completed. The pre-test analytical evaluation of methods, such as the use of thermal insulation, for reducing the amount of steam formed within the control system was completed. Detailed parameter studies were conducted on several control valve systems and also on several buffer systems to determine which systems are the most promising. Tests were conducted on the parallel-stepped Hy-Ball control system, using the cold-test loop which operates with water at room temperature. This system will be also tested, using the hot- test loop which operates with water at 572 un. Concent 85% F; construction of the hot-test loop is about 90% completed. (auth)
