A new system proposed for the generation of radioisotopes with accelerator neutrons by deuterons (GRAND) is described by mainly discussing the production of $$^{99}$$Mo used for nuclear medicine diagnosis. A prototype facility of this system consists of a cyclotron to produce intense accelerator neutrons from the $$^{nat}$$C(d,n) reaction with 40 MeV 2 mA deuteron beams, and a sublimation system to separate $$^{99m}$$Tc from an irradiated $$^{100}$$MoO$$_{3}$$ sample. About 9.7 TBq/week of $$^{99}$$Mo is produced by repeating irradiation on an enriched $$^{100}$$Mo sample (251g) with accelerator neutrons three times for two days. It meets about 10% of the $$^{99}$$Mo demand in Japan. The characteristic feature of the system lies in its capability to reliably produce a wide range of high-quality, carrier-free, carrier-added radioisotopes with a minimum level of radioactive wastes without using uranium. The system is compact in size, and easy to operate; therefore it could be used worldwide to produce radioisotopes for medical, research, and industrial applications.
