The natural uranium assembly, “QUINTA”, was irradiated with 2, 4, and 8GeV deuterons. The 232Th, 127I, and 129I samples have been exposed to secondary neutrons produced in the assembly at a 20-cm radial distance from the deuteron beam axis. The spectra of gamma rays emitted by the activated 232Th, 127I, and 129I samples have been analyzed and several tens of product nuclei have been identified. For each of those products, neutron-induced reaction rates have been determined. The transmutation power for the 129I samples is estimated. Experimental results were compared to those calculated with well-known stochastic and deterministic codes. •The natural uranium assembly, "QUINTA", was irradiated with 2, 4, and 8GeV deuterons.
