<P> At a meeting of the Atomic Energy Commission on 15 March 1955 , the decision was made to construct a small nuclear reactor at Trombay . The reactor would be used for training personnel for the operation of future reactors and for research , including experiments in nuclear physics , studying the effects of irradiation and the production of isotopes for medical , agricultural and industrial research . In October 1955 , an agreement was signed by the United Kingdom Atomic Energy Authority and the Indian Department of Atomic Energy , under which Britain would supply uranium fuel elements for a pool - type reactor to be designed by India . The agreement further ensured the `` close cooperation and mutual assistance between the Department and the Authority in the promotion and development of the peaceful uses of atomic energy , '' and provided for future design and collaboration in the construction of a high flux reactor at a later date . Named Apsara , the reactor was housed in a 100 x 50 x 70 concrete building . India 's and Asia 's first nuclear reactor , Apsara reached criticality at 3 : 45 p.m on 4 August 1956 and was inaugurated by Prime Minister Nehru on 20 January 1957 . </P>
