Koodankulam Reactor II Reaches Criticality, 9 Years behind Schedule
["Though it was originally planned to complete the construction of the
first two reactors within 60 months from the ‘first pouring of
concrete’ on March 31, 2002, it took 11 years for the Nuclear Power
Corporation of India Limited, the proponent of the project, to take
the first reactor to the criticality stage, owing to various reasons
including delay in supply of compo(nents.)"
So, there is a time overrun of more than nine years.]

Kudankulam plant reaches milestone

The second reactor of Kudankulam Nuclear Power Project (KKNPP)
attained criticality at 8.56 p.m. on Sunday.
The second reactor of Kudankulam Nuclear Power Project (KKNPP)
attained criticality at 8.56 p.m. on Sunday.
The event was greeted with thunderous applause from the employees,
technocrats and members of the Russian specialist group, exchange of
greetings and warm hugs.
As the top brass of the Nuclear Power Corporation of India Limited
including its Chairman and Managing Director S.K. Sharma witnessed the
milestone event from the control room, the nuclear fission started in
the second reactor at the scheduled time.
On commencing the First Approach to Criticality (FAC) at 7.52 p.m. on
Friday by withdrawing the control rods from the reactor, boron
dilution started four hours later to allow neutron concentration to go
up, which eventually led to the criticality of the reactor.
Once the reactor starts generating 400 MWe of power, possibly within
45 days from the date of criticality, it is likely to be connected to
the grid. Generation of power will be raised to 500 MWe, 750 MWe, 900
MWe and 1,000 MWe in stages. At every stage, various tests will be
conducted and the technical parameters verified as mandated by the
Atomic Energy Regulatory Board (AERB). Based on the results of the
tests at each stage and with AERB clearances, which will take two to
three weeks, subsequent stages will be reached to take the VVER
reactor constructed with Russian technical assistance to its maximum
capacity of 1,000 MWe.
Loading of 163 enriched uranium fuel assemblies into the light water
coolant reactor began on May 11 and was completed on May 19.
The KKNPP submitted its reports to the AERB and got the nod for
criticality after the Ministry of Environment, Forest and Climate
Change experts, inspected the second unit and submitted their report
to the Supreme Court.

The first unit, after attaining criticality in July 13, 2013 was
synchronised with the southern grid in October the same year. It has
generated 5,777 million units of power till May 2016. Tamil Nadu is
getting its share of 562.50 MWe from the first unit and neighbouring
Andhra Pradesh, Karnataka and Kerala are getting 50 MWe, 221 MWe and
133 MWe respectively from the first reactor while the Union Territory
of Puducherry’s share stands at 33.50 MWe.
Tamil Nadu is expected to get a minimum of 462.50 MWe from the second unit.
Having successfully accomplished the mission by operationalising the
first two reactors, the KKNPP will now pay more attention for
commencing the work on the construction of the third and fourth
reactors, each with a capacity of 1,000 MWe, at an outlay of Rs.
39,500 crore.
