The first fuel assembly was successfully loaded into the reactor of the second unit of Kudankulam Nuclear Power Plant (KNPP) on Wednesday — signalling that power generation at the unit will commence soon.
A total of 163 fuel assemblies will be loaded into the reactor. Upon completion of the required tests the second unit will be brought to the first criticality status under the absolute supervision and approval of the Atomic Energy Regulatory Board.
KNPP started commercial operations on December 31, 2014 and the first unit generates 1000 MW of power.
According to sources, this is the first NPP in the world where the post-Fukushima safety enhancement requirements have already been implemented and being operated successfully.
“The analysis was conducted for the possibility of KNPP core cooling under postulated beyond design basis accident with tsunami which leads to failure of power supply systems and water supply systems similar to those happened at Fukushima NPP. It was defined that Kudankulam NPP is equipped with sufficient passive systems ensuring core cooling as well as restriction of radiation exposure even in case of long-term black out of electricity sources and failure of the water supply systems provided in the design,” the sources said.
