1 SafeN130 Movable Apparatus for Radioactive Noble Gases Removing

2 Introduction The movable apparatus for removing radioactive noble gases which is developed from DS SCIENCE INC (Model SafeN130), is a prevention device for the worker's radioactive exposure and the environment pollution by removing the existing radioactive noble gases in the inside air of high pollution area(s/g, PZR etc.) in the building of nuclear power plant during OverHaul(O/H) period. Features Removing the noble gases up to 99% (Xe, Kr, Ar etc.) The bigger removing capacity than the existing removing capacity. about 28times(2.5CFM 70CFM) Movable compact size Easy to use (Convenient Assemble and Disassemble) Moving by 2 person. When the temperature is 4 ~90, the humidity is 10%~99% and the inhaling rate is Developed by Original Korea technology 0.05m 3 /min~10m 3 /min of the inhaling air, the maximum removing rate of this device is following, the decontamination factor (DF, the valuation of output value from input) is in less then 10E+04±100 purification ability, it can impound and remove up to 99% until 100Ci radioactive capacity of all gases.

4 Test result The analysis test at the former section of the first noble gases removing device - Confirming supplying the Xenon gases in to the trap by supplying variety concentration Xenon(Xe) (680ppm, 455ppm, 240ppm, 87ppm) The analysis test at the rear section of the second noble gases removing trap - Confirming detecting Xenon(Xe) in the gas which is passing first and second noble gases removing trap. As blow table, Xenon(Xe) is not detected. (Total test period : 22hours) The test result, confirming that Xenon gas is absorbed by noble gas removing device and after increasing temperature, the gas is exhausted. (We can confirm the noble gas device absorb the Xenon(Xe)) SafeN130 Specifications Ⅰ. Radioactive noble gases removing device Ⅱ.
