The transport behavior of trace-amount of radio nuclides such as I and Cs (Cs) in sodium have been studied on both conditions of normal sodium-steam reaction and sodium burning brought by excess steam supplying. trapping of these radio nuclides transported into gas phase in gas bubbler or scrubber, which is a component of waste gas treatment system, was also discussed. main experimental results were as follows: (1) under the normal sodium-steam reaction, partition ratio of Cs trans-ported into gas phase was 410, while those of I and Na were one hundred times smaller than that of 134cs. Chemical forms of Cs and I transported into gas phase were estimated to be cesium hydroxide and inorganic iodine such as nai, respectively. (2) when the sodium burning occurred by excess steam supplying, partitionratios of Na, I increased 250500 times larger than those under the normal sodium-steam reaction, while for Cs, it increased about 25 times larger than that under normal reaction. sma
