Impurity analysis of an irradiated low activation vanadium alloy specimen are being performed by radioactivity measurement. Result of gamma-ray spectrum measurement for the specimen irradiated 15 years ago will be reported. Merits of the analysis using a material testing reactor will also be discussed by comparing with those using a 14 MeV neutron source.
