<P> On 23 March 1948, Prime Minister Jawaharlal Nehru introduced the Atomic Energy Bill in the Indian Parliament, and it was subsequently passed as the Indian Atomic Energy Act . Modelled on the British Atomic Energy Act 1946, the Act granted sweeping powers to the central government over nuclear science and research, including surveying for atomic minerals, the development of such mineral resources on an industrial scale, conducting research regarding the scientific and technical problems connected with developing atomic energy for peaceful purposes, the training and education of the necessary personnel and the fostering of fundamental research in the nuclear sciences in Indian laboratories, institutes and universities . Around the same time, the Government of West Bengal sanctioned the construction of a nuclear physics institute under the University of Calcutta; the cornerstone was laid in May 1948, and the institute was inaugurated on 11 January 1950 by Irène Joliot - Curie . </P> <P> With effect from 1 June 1948, the Advisory Board for Research in Atomic Energy, together with its parent organisation the CSIR, was folded into the new Department of Scientific Research and placed directly under the Prime Minister . On 3 August 1948, the Atomic Energy Commission of India (AEC) was established and made separate from the Department of Scientific Research, with Bhabha as its first chairman . In January 1949, the AEC met to formulate a uniform under - and post-graduate university syllabus for theoretical and fundamental physics and chemistry, to guarantee sufficient numbers of nuclear scientists and to ensure they would receive consistent levels of training and education . In the same year, the Tata Institute of Fundamental Research was designated by the CSIR as the hub for all major nuclear science research projects . In 1950, the government announced it would purchase all available stocks of uranium and beryllium minerals and ores, and declared large rewards for any significant discoveries of the same . On 3 January 1954, the Atomic Energy Establishment, Trombay (AEET) was established by the Atomic Energy Commission to consolidate all nuclear reactor research and technology - related developments; on 3 August, the Atomic Energy Commission and all its subordinate agencies, including the Tata Institute of Fundamental Research and the nuclear research institute at Calcutta University, were transferred to the new Department of Atomic Energy and placed under the direct charge of the Prime Minister's Office . </P> <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> <P> In April 1955, the Canadian government under Prime Minister Louis St. Laurent offered to assist in building an NRX - type reactor for India under the Colombo Plan, of which both India and Canada were then members . Prime Minister St. Laurent expressed hopes the reactor would serve India well in the development of peaceful atomic research and development . On behalf of the Indian government, Nehru formally accepted the offer that September, stating the reactor would be made available to any accredited foreign scientists, including those from other Colombo Plan member states . On 28 April 1956, Nehru and the Canadian High Commissioner to India Escott Reid signed an agreement for a "Canada - India Colombo Plan Atomic Reactor Project ." Under the terms of the agreement, Canada would provide a 40 MW CIRUS reactor for solely research purposes, including the initial manufacture and engineering of the reactor, and would also provide technical expertise, including training Indian personnel in its operation . India would supply the reactor site and foundation, and would also pay all "internal" costs, including the construction of the reactor complex, the costs of local labour and any shipping and insurance fees . Under Article II of the agreement, India would make the reactor facilities available to other Colombo Plan nations . Article III stipulated that the "reactor and any products resulting from its use will be employed for peaceful purposes only;" at the time, however, there were no effective safeguards to ensure this clause . A further agreement was made with the United States government to supply 21 tons of heavy water for the reactor . Construction of the reactor began later in 1956, with Indian technical personnel sent to Chalk River for training . CIRUS was completed in early 1960 and after achieving criticality in July 1960, was inaugurated by Nehru in January 1961 . Construction of a third research reactor, ZERLINA (Zero Energy Reactor for Lattice Investigations and New Assemblies) began at Trombay in 1958; ZERLINA was also commissioned in 1961 . </P>
