<p>PROBLEM TO BE SOLVED: To reduce the burden of a rear-stage waste gas processing system so as to reduce its processing cost by providing a pulsator capable of reducing the amount of radioactive gas generated. SOLUTION: This pulsator includes a container main body 1 for temporarily retaining a radioactive waste liquid 3 and dispensing it into a waste liquid disposal system, a cylindrical element 17 disposed within the main body 1 and having its lower end opened near the bottom of the main body 1, and an actuating air feeding and exhausting means 20 for feeding and exhausting actuating air 7 to and from the upper end of the cylindrical element 17. The waste liquid 3 in the cylindrical element 17 is made to flow in and out as the actuating air 7 is fed and exhausted by the feeding and exhausting means 20 so as to agitate the waste liquid 3 in the main body 1. The cylindrical element 17 is constructed as a multiple body comprising a main cylindrical element 15 and an appropriate number of auxiliary cylindrical elements 16 surrounding the main cylindrical element 15 in concentric circles, and the feeding and exhausting means 20 is constructed so that the actuating air 7 introduced into the main cylindrical element 15 is discharged into the auxiliary cylindrical elements 16 and reused.</p> |
