English: Foreseeing a growing demand for radioisotopes and advanced research in nuclear science, the necessity for another reactor with comparatively higher neutron flux was felt way back in the 1970s, which ultimately resulted in the construction and commissioning of the R-5 reactor (later renamed as Dhruva reactor) at BARC, Trombay.
