Operation Smiling Buddha or Operation Happy Krishna was the assigned code name of India's first successful nuclear bomb test on 18 May 1974. The bomb was detonated on the army base Pokhran Test Range (PTR), in Rajasthan, by the Indian Army under the supervision of several key Indian generals.
Pokhran is a town and a municipality located 112 km east of Jaisalmer city in the Jaisalmer district of the Indian state of Rajasthan. It is situated in the Thar Desert region. Surrounded by rocks, sand and five salt ranges, the word "Pokaran" (पोकरण) means "place surrounded by five salt-ranges" in Rajasthani. The site for India's first and second underground nuclear weapon test is near Pokhran.
India possesses nuclear weapons and previously developed chemical weapons. Although India has not released any official statements about the size of its nuclear arsenal, recent estimates suggest that India has 164 nuclear weapons and has produced enough weapons-grade plutonium for up to 200 nuclear weapons. In 1999, India was estimated to have 800 kilograms (1,800 lb) of separated reactor-grade plutonium, with a total amount of 8,300 kilograms (18,300 lb) of civilian plutonium, enough for approximately 1,000 nuclear weapons. India has conducted nuclear weapons tests in a pair of series namely Pokhran I and Pokhran II.
Raja Ramanna was an Indian physicist who is best known for his role in India's nuclear program during its early stages.
Homi Jehangir Bhabha, FNI, FASc, FRS, Hon.FRSE was an Indian nuclear physicist who is widely credited as the "father of the Indian nuclear programme". He was the founding director and professor of physics at the Tata Institute of Fundamental Research (TIFR), as well as the founding director of the Atomic Energy Establishment, Trombay (AEET) which was renamed the Bhabha Atomic Research Centre in his honour. TIFR and AEET served as the cornerstone of the Indian nuclear energy and weapons programme. He was the first chairman of the Indian Atomic Energy Commission and secretary of the Department of Atomic Energy. By supporting space science projects which initially derived their funding from the AEC, he played an important role in the birth of the Indian space programme.
Anil Kakodkar, is an Indian nuclear physicist and mechanical engineer. He was the chairman of the Atomic Energy Commission of India and the Secretary to the Government of India, he was the Director of the Bhabha Atomic Research Centre, Trombay from 1996 to 2000. He was awarded the Padma Vibhushan, India's second highest civilian honour, on 26 January 2009.
Since their public debut in August 1945, nuclear weapons and their potential effects have been a recurring motif in popular culture, to the extent that the decades of the Cold War are often referred to as the "atomic age".
The Bhabha Atomic Research Centre (BARC) is India's premier nuclear research facility, headquartered in Trombay, Mumbai, Maharashtra, India. It was founded by Homi Jehangir Bhabha as the Atomic Energy Establishment, Trombay (AEET) in January 1954 as a multidisciplinary research program essential for India's nuclear program. It operates under the Department of Atomic Energy (DAE), which is directly overseen by the Prime Minister of India.
The Pokhran-II tests were a series of five nuclear bomb test explosions conducted by India at the Indian Army's Pokhran Test Range in May 1998. It was the second instance of nuclear testing conducted by India; the first test, code-named Smiling Buddha, was conducted in May 1974.
CIRUS was a research reactor at the Bhabha Atomic Research Center (BARC) in Trombay near Mumbai, India. CIRUS was supplied by Canada in 1954, but used heavy water supplied by the United States. It was the second nuclear reactor to be built in India.
The Nuclear Command Authority (NCA) of India is the authority responsible for command, control and operational decisions regarding India's nuclear weapons programme. It comprises a Political Council headed by the Prime Minister of India and an Executive Council headed by the National Security Advisor.
The Dhruva reactor is India's largest nuclear research reactor. It was the first nuclear reactor in Asia proper. Located in the Mumbai suburb of Trombay at the Bhabha Atomic Research Centre (BARC), it is India's primary generator of weapons-grade plutonium-bearing spent fuel for its nuclear weapons program. Originally named the R-5, this open pool reactor first went critical on 8 August 1985 after 10 years of construction. However, the unit did not attain full power until 1988. The reactor experienced at least one serious accident when 4 metric tons of heavy water overflowed from the reactor core in 1985 following vibration problems.
Chagai-I is the code name of five simultaneous underground nuclear tests conducted by Pakistan at 15:15 hrs PKT on 28 May 1998. The tests were performed at Ras Koh Hills in the Chagai District of Balochistan Province.
The Department of Atomic Energy (DAE) is an Indian government department with headquarters in Mumbai, Maharashtra, India. DAE was established in 1954 with Jawaharlal Nehru as its first minister and Homi Bhabha as its secretary.
The Atomic Energy Commission of India is the governing body of the Department of Atomic Energy (DAE), Government of India. The DAE is under the direct charge of the Prime Minister.
Rajagopala Chidambaram is an Indian Physicist who is known for his integral role in India's nuclear weapons program; he coordinated test preparation for the Pokhran-I (1975) and Pokhran-II (1998).
India's three-stage nuclear power programme was formulated by Homi Bhabha, the well-known physicist, in the 1950s to secure the country's long term energy independence, through the use of uranium and thorium reserves found in the monazite sands of coastal regions of South India. The ultimate focus of the programme is on enabling the thorium reserves of India to be utilised in meeting the country's energy requirements. Thorium is particularly attractive for India, as India has only around 1–2% of the global uranium reserves, but one of the largest shares of global thorium reserves at about 25% of the world's known thorium reserves. However, thorium is more difficult to use than uranium as a fuel because it requires breeding, and global uranium prices remain low enough that breeding is not cost effective.
The Prime Minister's Office (PMO) consists of the immediate staff of the Prime Minister of India, as well as multiple levels of support staff reporting to the Prime Minister. The PMO is headed by the Principal Secretary, currently Pramod Kumar Mishra. The PMO was originally called the Prime Minister's Secretariat until 1977, when it was renamed during the Morarji Desai ministry.
Valangiman Subramanian Ramamurthy is an Indian nuclear physicist with a broad range of contributions from basic research to Science and Engineering administration.Prof.Ramamurthy started his career in Bhabha Atomic Research Centre, Mumbai in the year 1963. He made important research contributions in the area of nuclear fission, medium energy heavy ion reactions, statistical and thermodynamic properties of nuclei and low energy accelerator applications. During the period 1995-2006, Prof.Ramamurthy was fully involved in Science administration as Secretary to Government of India, Department of Science and Technology, (DST), New Delhi.Other important assignments held by him include Director, Institute of Physics, Bhubaneswar, (1989-1995), DAE Homi Bhabha Chair in the Inter-University Accelerator Centre, New Delhi (2006-2010), and Director of the National Institute of Advanced Studies, Bengaluru (2009-2014). He is a former chairman of the Recruitment and Assessment Board of the Council of Scientific and Industrial Research and has served as a member of the design team of the first Indian nuclear experiment in Pokhran on 18 May 1974. The Government of India awarded him the third highest Indian civilian honour of Padma Bhushan in 2005.
Satinder Kumar Sikka was an Indian nuclear condensed matter physicist, crystallographer and a former Scientific Secretary to the Principal Scientific Advisor of the Government of India. He was known to have played a crucial role, along with Raja Ramanna, Rajagopala Chidambaram and Basanti Dulal Nagchaudhuri, in the design and development of a Hydrogen Bomb by India, which was tested at the Pokhran Test Range in May 1998, under the code name, Operation Shakthi. He was also involved in the Smiling Buddha tests, conducted in 1974. He was awarded the fourth highest civilian award of the Padma Shri, by the Government of India, in 1999.
