Radionuclide scrubbing in water pools - gas-liquid hydrodynamics

Creators

  • 1. Battelle Columbus Labs., OH

Description

During severe core damage accidents, the amount of radioactive aerosols retained in the water pools of BWR and PWR power plants is expected to be dependent on the gas-liquid hydrodynamics of the system. Experimental studies of gas-liquid hydrodynamics have been conducted to support aerosol removal experiments at Battelle Columbus and to provide data for model validation. Tests have been conducted using mixtures of condensable (superheated steam) and noncondensable (air, helium, or hydrogen) gases injected into water pools. Expressions have been developed which describe the initial vapor globule size and emission frequency at the injector outlet, the breakup of hydrodynamically unstable vapor globules, the ultimate size distribution of gas bubbles in a water pool, and the spatial variations in the bubble rise velocities as a function of injector geometry and flow conditions
