Chennai: The 1,000
MW nuclear power plant at Kudankulam in Tamil Nadu restarted power
generation on Sunday evening, said Power System Operation Corporation
Ltd (POSOCO) which operates the national grid.
The unit went down on February 4 night following a steam leak in the feed water system in the turbine building.
The unit was expected to restart on February 7 but got delayed, said POSOCO.
On Sunday, the unit touched a peak generation of 413 MW at 10.41 pm while the average generation for the day was five MW.
India's atomic power plant operator Nuclear Power Corporation of India Ltd (NPCIL) is setting up two 1,000 MW atomic power plants at Kudankulam in Tirunelvelli district, about 650 km from here, at an outlay of over Rs.17,000 crore.
The first unit attained criticality, which is the beginning of the nuclear fission process, in July 2013.
Subsequently it was connected to the southern grid in October 2013.
However, commercial power generation began only on December 31, 2014.
The unit also experienced breakdowns after commercial production started.
The unit was shut down in June 2015 for 60 days for refuelling and annual maintenance.
Operating at full capacity, the unit supplies power to Tamil Nadu (562.5 MW), Puducherry (33.5 MW), Kerala (133 MW), Karnataka (221 MW) and Andhra Pradesh (50 MW).
The NPCIL skipped several deadlines in restarting the first unit and finally on January 21, 2016 the reactor restarted the fission process and was connected to the southern grid on January 30.
According to the official position, the second 1,000 MW unit at Kudankulam is expected to go critical, or start the fission process, for the first time sometime this year.
However, sources in the know told IANS that the unit may go critical early next year.
The second unit has to get some parts from Russia as some of its components have been used in the first unit so that the latter could start operating fast.
The fuel has to be loaded into the second reactor.
A senior official in the Atomic Energy Regulatory Board (AERB) recently told IANS that the results of the second unit's commissioning and inspection reports are being studied.
"After the reports are studied AERB might lay down some conditions which have to be completed before NPCIL applies for the permission to load the fuel," he had said.
The AERB has given its nod for site preparation work for building the third and fourth units at Kudankulam. The two units would cost about Rs.40,000 crore.
