A case study is presented here on the continued development efforts at the Bhabha Atomic Research Centre on instrumented pipeline inspection gauge for Indian Oil Corporation Limited over the last two decades. A marvel of technology involving challenges of non-destructive testing techniques, mechanical, magnetism, electronics, data processing and analysis, operational safety requirements and portability, qualifications of the tools and characterization of defects with acceptable accuracy were achieved to be at par with the internationally available tools. These tools are being extensively deployed in the field. The homegrown technology for in-line inspection has brought down the cost of the tool and that of the services per kilometre. Different technologies are now being pursued to ensure that the in-line inspection work in the country is carried out in an ‘Atmanirbhar’ way.Full Text

This article provides a case study of antenna control servo system development in the Department of Atomic Energy over the last five decades, starting with the pioneering efforts for Ooty Radio Telescope (1970) and Arvi Earth Station (1971). While tracing the evolution of technology, the challenges and motivations, we evaluate these efforts against the basic tenets espoused by Homi Bhabha and Vikram Sarabhai for the growth of science and technology in India, viz. self-reliance with commercial viability.Full Text
