Research Abstract

Studies have been made for developing a sensitive device for monitoring possible release of fission products from fuel elements of a pool-type reactor. Nitrogen gas bubbles were introduced into the reactor-coolant water to extract dissolved fission rare gases, ^<88>Kr, ^<89>Kr and ^<138>Xe, and their daughter nuclides, ^<88>Rb, ^<89>Rb and ^<138>Cs, were counted with high efficiency. Various causes that influence the efficiency of extraction the rare gases and of collection the daughter nuclides were studied by two continuous method. : (1) a "rotating bottle filled with collecting solution method" in which the bubbled gas was injected the solution and the rare gases were collected into the solution and (2) a "counter-current flow column method" in which the bubbled gas was fed from the bottom into the column and flows upward in the column, otherwise the carrier solution was led into the top of the column along the inner wall laminated with cotton mesh and flows downward counter-currently to the gas flow. During the flow, the solution collects the daughter nuclides of the rare gases and takes them out of column. On the both methods effluent solution was transferred continuously to a detector head of Ge-detector for gamma-ray spectrometry.
