PM congratulates DRDO, Indian Navy for INS Arihant nuke reactor going critical
In his message, Dr. Singh said:
"I am delighted to learn that the nuclear propulsion reactor on board INS
Arihant, India's first indigenous nuclear powered submarine, has now achieved
criticality. I extend my congratulations to all those associated with this
important milestone, particularly the Department of Atomic Energy, the Indian
Navy and the Defence Research and Development Organization.
Dr. Singh further said that
Saturday's development represents "a giant stride in the progress of our
indigenous technological capabilities."
"It is testimony to the ability
of our scientists, technologists and defence personnel to work together for
mastering complex technologies in the service of our nation's security,"
he added.
The Prime Minister said that he
looked forward to the early commissioning of the INS Arihant.
The INS Arihant achieved nuclear
criticality early on Saturday morning.
Sources were quoted by the media, as
saying that the 83-megawatt pressurized light-water reactor attained
"criticality" after several months of "checking and
re-checking" of all the systems and sub-systems of the 6000-tonne
submarine at the secretive ship-building centre at Visakhapatnam.
The INS Arihant was till now being
tested in the harbor on shore-based, high-pressure steam.
With the reactor going critical now,
the submarine will eventually head for open waters for extensive "sea-
acceptance trials", which will include firing of its 750-km range K-15
ballistic missiles.
The sea trials will take at least
another 18 months before INS Arihant can become fully operational.
When that happens, India will
finally get the long-elusive third leg of its nuclear triad - the capability to
fire nuclear weapons from the land, air and sea.
The first two legs - the rail and
road-mobile Agni series of ballistic missiles and fighters like Sukhoi 30MKIs
and Mirage-2000s capable of delivering nuclear warheads - are already in place
with the armed forces.
The capability to deploy
submarine-launched ballistic missiles (SLBMs) is crucial since India has a
declared "no first-use policy" for nuclear weapons, and hence needs a
robust and viable second-strike capability. (ANI)
