Reactor of India's first nuclear submarine INS Arihant goes 'critical'

August 10, 2013

Reactor_of_IndiaNew Delhi, Aug 10: India on Friday night activated the miniature reactor on board the country's first indigenous nuclear submarine INS Arihant.

With this, the country has moved a step towards completing the nuclear troika - capability to launch nuclear weapons from land, air and sea.

According to a news channel report, all systems of the indigenously-made 83 MW pressurised light-water reactor are "go" after many rounds of checking and re-checking.

The 6,000-tonne submarine at the secretive ship-building centre at Visakhapatnam will soon be launched to sea on the Eastern coast.

India is the only nation in the Indian Ocean region to have a nuclear submarine and the sixth in the world to have the capability to design and construct a nuclear submarine

The orange beacon atop the conning tower came to life on July 26, 2009, as Prime Minister Manmohan Singh's wife Gursharan Kaur had pressed the button to symbolise the launching of the vessel into water.

In the middle of the body - comprising an outer hull through which the water goes in and an inner pressurised hull - on the starboard side are two rectangular vents, meant to take in water when the vessel dives into the sea. It is like a "cocoon within a cocoon", an official had explained.

INS Arihant is longer than any of the submarine in the Indian Navy's fleet so far. A nuclear submarine is powered by a nuclear reactor, which generates tremendous heat driving a steam turbine. It has unlimited underwater endurance and speed twice that of its conventional counterparts.

The submarine can carry 12 nuclear missiles K-15. Keeping in line with its "no first use policy", the submarine will help India in developing a "credible second strike capability" in case of nuclear attack, said officials.

Indian Navy has been operating conventional diesel-electric submarines, which have to surface to charge their batteries.

Mumbai, Feb 18: A group of citizens on Tuesday demanded a thorough inquiry into the death of special CBI judge Brijgopal Harkishan Loya in 2014.

The group has written a letter to Maharashtra Chief Minister Uddhav Thackeray, seeking a time-bound probe into the death of Loya.

Loya, who was hearing the high-profile Sohrabuddin Sheikh fake encounter case of Gujarat, died of a cardiac arrest in Nagpur on December 1, 2014, when he had gone to attend the wedding of a colleague's daughter.

Social activist Ashok Pai, addressing a press conference on behalf of the group, also demanded proper compensation for the judge's family, saying he was on an "official" tour.

Pai said on Tuesday he met NCP president Sharad Pawar, whose party is a key constituent of the Maha Vikas Aghadi (MVA) government in Maharashtra, and raised these demands with him.

Pawar assured to look into the demands, he said at the press conference at the Mumbai Marathi Patrakar Sangh.

"We have handed over a letter to Maharashtra Assembly speaker Nana Patole and dispatched a copy of the letter to Chief Minister Uddhav Thackeray (seeking a probe into Loya's death)," Pai said.

As the matter relates to "mysterious" death of a sitting judge of the CBI, all facts about it must be made public after a detailed and time-bound probe, Pai said.

The Loya death case had reached the Supreme Court.

The Supreme Court had held that Loya had died of "natural causes" and had rejected PILs seeking an SIT probe into the death, questioning their motive.

The SC had held that petitions were moved by political rivals to settle scores which was a serious attempt to scandalise the judiciary and obstruct the course of justice through a "frontal attack" on its independence.
