Radiochemical Neutron Activation Analysis for Trace Chlorine in Steels and Alloys

摘要

Chlorine is usually present at low concentrations in reactor materials and thermal neutron activation of ~35Cl produces ~36Cl, which has a long half-life and is a radio- muclide of significance in nuclear waste disposal. This paper describes a radiochemical method that has been developed to measure low concentrations of Cl in reactor stainless steels, so that the amount of ~36Cl in radioactive wastes can be estimated.
