“…3 35 Cl is found as an impurity in concrete and many other components associated with the reactor. [4][5][6] Although the levels of 35 Cl are low (ppm), the high neutron reaction cross section (43 barns), and the volume of material (tonnes), result in the nuclear reaction being an important contributor to the radionuclide inventory of the concrete. The full speciation of chlorine in nuclear wastes has yet to be determined, but studies have indicated that 35 Cl in concrete will be mainly present as chloride.…”

A method has been developed for the measurement of chlorine and iodine radionuclides in concrete wastes generated from the decommissioning of nuclear power stations. Sequential oxidation of 129 I and 36 Cl from samples of concrete takes less than 7 h and the method is relatively simple and can be used to reliably determine low levels of 129 I and 36 Cl. Generally, recoveries for the procedure are high (in excess of 70%) and large sample sizes can be tolerated ( ~1-10 g). This paper describes the development of the method and demonstrates a relatively simple, repeatable process for the measurement of 129 I and 36 Cl in concrete wastes. The equipment and the methods used should be available at most reactor sites or nuclear plants.
