Sorption of fission products on surface of loop contour

Distribution of the fission products has been studied in a loop contour of the atomic reactor with the aid of the unique procedure residing in that the samples of a coolant have been taken periodically from a ''small' water loop of the reactor SM-2 where a defect fuel element has been placed with a known value of the open fuel surface, i.e. with a known amount of fission products yield in the coolant. The amount of fission products sorbed on the surfaces of rustproof tubes of the contour has been calculated. The treatment of the results makes it possible to develop a sorption model for the fission products from water low parameter and to determine the coefficients of sorption on a rustproof surface of the contour at neutral pH
