Kudankulam n-plant restarts


Chennai: On Sunday evening, a 1000 MW nuclear power plant at Kudankulam in Tamil Nadu restarted power generation. The Power System Operation Corporation Ltd (POSOCO) will be operating the national grid.

The unit went down on February 4 night following a steam leak in the feed water system in the turbine building.

As per reports, the unit was expected to begin functioning on February 7 but it was delayed. The unit touched the peak of its power generation of 413 MW at 10.41 p.m.

The average power generation per day as per the rates 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.

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.

The fuel has to be loaded into the second reactor. A senior official in the Atomic Energy Regulatory Board (AERB) recently made a statement 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.
