ABSTRACT:
A method is disclosed for determining the concentration of fission products in the reactor coolant of a liquid metal cooled nuclear reactor. Reactor coolant is bypassed at constant temperatures and constant velocity through a flow sampling system containing a sampling tube. After a period of time, the sampling tube is isolated and removed from the bypass system; the liquid metal coolant is removed from the tube; and, the radionuclides deposited on the sampling tube are measured by gamma spectroscopy. The concentration of fission products in the reactor coolant is then determined from the measured radioactivity of the deposited nuclides.
