Queried about the tripping, a senior official of the Atomic Energy Regulatory Board (AERB), preferring anonymity, told IANS: "There is no problem as far as the safety of the plant is concerned. Such things happen even in other thermal/hydel power plants as well."
A source closely associated with KNPP told IANS: "The tripping of the unit due to reverse power may be due to several reasons including due to the problem in the transmission line/grid. Normally it would take some days for a unit of KNPP size to stabilise".
The Nuclear Power Corporation of India Ltd (NPCIL) has set up two 1,000 MW Russian reactors at Kudankulam in Tirunelveli district, around 650 km from here. The total outlay for the project is over Rs.17,000 crore.
KNPP is India's first pressurised water reactor belonging to the light water reactor category.
The first unit attained criticality, which is the beginning of the fission process, for the first time in July 2013.
In August, the AERB gave its nod to KNPP to raise the reactor power levels to 50 percent and synchronisation of the unit with the power grid.
The NPCIL earlier said it would connect the first unit to the grid end-August, generating 400 MW power.
