The natural uranium assembly, "QUINTA", was irradiated with 2, 4, and 8 GeV deuterons. The Th-232, I-127, and I-129 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 Th-232, I-127, and I-129 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 I-129 samples is estimated. Experimental results were compared to those calculated with well-known stochastic and deterministic codes.
