which is the first nuclear submarine to be designed and built in india
Arihant-class submarine The Arihant-class submarines are nuclear powered ballistic missile submarines built under the Advanced Technology Vessel (ATV) project.[21][22][23][24][25][26] They will be the first nuclear submarines designed and built by India.[27] The submarines are 112 m (367 ft) long with a beam of 11 m (36 ft), a draught of 10 m (33 ft), displacement of 6,000 tonnes (5,900 long tons; 6,600 short tons) and a diving depth of 300 m (980 ft). The complement is about 95, including officers and sailors.[28] The boats are powered by a single seven blade propeller powered by an 83 MW (111,000 hp) pressurised water reactor and can achieve a maximum speed of 12–15 knots (22–28 km/h) when surfaced and 24 knots (44 km/h) when submerged.[28]
Indira Gandhi Centre for Atomic Research Indira Gandhi Centre for Atomic Research (IGCAR) is one of India's premier nuclear research centres. It is the second largest establishment of the Department of Atomic Energy (DAE), next to Bhabha Atomic Research Centre (BARC), located at Kalpakkam, 80Â km south of Chennai, India.[1] It was established in 1971 as an exclusive centre dedicated to the pursuit of fast reactor science and technology, due to the vision of Dr. Vikram Sarabhai.[2] Originally, it was called as Reactor Research Centre (RRC). It was renamed as Indira Gandhi Centre for Atomic Research (IGCAR) by the then Prime Minister of India, Rajiv Gandhi in December 1985.[3] The centre is engaged in broad-based multidisciplinary programme of scientific research and advanced engineering directed towards the development of Fast Breeder Reactor technology, in India.[1]
