Director, BARC – B. Bhattacharjee

Shri B. Bhattacharjee took over as Director, on April 3, 2001. Earlier, he was Project Director, Rare Materials Project, Mysore, and Director, Chemical Engineering and Technology Group, BARC. He was a key person in the building of the Uranium Corporation of India Limited, Jaduguda, Bihar, which supplies the entire uranium needed for India’s nuclear electricity programme. Later, Bhattacharjee switched over to multidisciplinary R & D activities at BARC, Mumbai, for the development of High Speed Rotor (HSR) needed for producing enriched uranium and other strategic materials. The successful commissioning of HSR technology in India has put the country among a select band and enabled production of some materials of “strategic importance”. Bhattacharjee played a key role in two other projects: desalination plant coupled to a nuclear electricity station and the Special Materials Project. BARC has already supplied 15 desalination plants to different States. A massive desalination plant, adjacent to the Madras Atomic Power Station at Kalpakkam (NDDP), was also constructed under his guidance.

Director, BARC – A. N. Prasad

Dr. A. N. Prasad, is a distinguished nuclear scientist and an international authority on the issue of Safeguards. He earned his Masters degrees in nuclear power engineering from the Indian Institute of Science, Bangalore, did his advanced nuclear science and technology from Bombay and nuclear chemical engineering from Oak Ridge School of Reactor Technology, USA.  He played a key role in the setting up of India’s first fuel reprocessing plant at Trombay in 1964 to separate plutonium. With this, India became only the fifth country in the world to develop this technology, the others being USA, the then USSR, the UK and France. During his long tenure in the nuclear establishment he continued to work on high technology areas of relevance to the nuclear fuel cycle, particularly specializing in what is called the ‘back end of the fuel cycle’. He was also chairman of the safeguards committee of the Department of Atomic Energy for a number of years. In recognition of his outstanding contributions to the development of nuclear technology in India, he was appointed director of BARC and member, Indian Atomic Energy Commission, in May 1993.

Chairman, AEC – Ratan Kumar Sinha

Ratan Kumar Sinha is an Indian nuclear scientist and mechanical engineer. He had served as the Secretary to the Government of India, Department of Atomic Energy(DAE) and Chairman of the Atomic Energy Commission(AEC), Government of India from April 2012 to October 2015. Prior to that, Ratan Kumar Sinha had served as Director of Bhabha Atomic Research Centre (BARC), Mumbai from May 2010 to June 2012.[2]During his four decades of illustrious career, Ratan Kumar Sinha held several important positions related to design & development of nuclear reactors for the Indian nuclear programme. He has been actively involved in the development of Advanced Heavy Water Reactor (AHWR) and Compact High Temperature Reactor (CHTR), two of the highly acknowledged technological innovations which are suitable for large scale deployment of nuclear power, particularly in Indian scenario.

As Chairman, AEC and Secretary, DAE, Ratan Kumar Sinha had put special thrust on several key deliverables for sustainable development and deployment of nuclear energy. Major thrust areas, in continuation to his research at BARC, include advanced nuclear energy systems for thorium utilisation and accelerator technology. He had given high priority to application of radiation technology in the areas of healthcare management, agriculture, food preservation and water purification. He had also strengthened outreach activities of DAE for spreading awareness about the peaceful uses of atomic energy among the general public. He had been instrumental in kick starting several public outreach campaigns to present the human face of India’s nuclear capabilities. Under his leadership, DAE displayed its first ever tableau in the 66th Republic Day Parade 2015 and had launched its social media page on Facebook ( as a part of public outreach initiatives.

Ratan Kumar Sinha has coined the phrase राष्ट्र की सेवा में परमाणु (Atoms in Service of the Nation) which has been imbibed as the motto of the Department of Atomic Energy. Motto of DAE is a part of the new logo of DAE launched in January 2014.
