Abstract

Charged particle activation analysis is used for the determination of boron, carbon and nitrogen in zircaloy. Carbon can be determined instrumentally using the ^12^C (d,n) ^13^N reaction. For the determination of boron and nitrogen the ^10^B (d, n) ^11^C and the ^14^N (α, αn) ^13^N reactions are used. ^11^C is separated as ^11^Co~2~ formed by dissolution of the sample in an oxidizing solution. Carbondioxide is trapped in sodiumhydroxyde. ^13^N is separated as ^13^NH~3~ which is trapped in 10 ml of 0.2 M hydrochloric acid. The yield of the chemical separations is determined experimentally. Concentrations of 0.163, 113.4 and 36.8 μg g~−1~ are obtained for boron, carbon and nitrogen respectively.
