摘要：
Filtered containment venting system (FCVS) is an essential technology in nuclear power plants for the removal of iodine. A laboratory scale venturi scrubber has been designed, developed and fabricated.The maximum removal efficiency of iodine is obtained as 82.32% at 3 x 10(-3) kmol/m(3) of KI solution, used as the scrubbing liquid for the throat gas velocity of 18 m/s and liquid flow rate of 0.033 kg/s with iodine inlet concentration of 0.39 kg/m(3). A semiempirical model has been developed to predict the removal efficiency of iodine scrubbing using the experimental results and the variables which show the impact on the scrubber performance.
