Abstract

When a nuclear reactor is dismantled the residual radioactivity in concrete used in the reactor poses problems of treatment and disposal. Neutron activation techniques were used for the quantitative determination of chlorine, calcium, nickel, cobalt, europium, samarium, and niobium in 21 samples of concrete taken from different German, Italian, English and French nuclear reactors. In addition to those elements giving the largest quantities of long-lived radioisotopes, the study shows that numerous other elements can be determined analytically without chemical separation. Knowledge of the strengths of the different elements permits the radioactivity of concretes used in nuclear reactors to be calculated at the time of their eventual dismantlement.
