Hours after restarting it, Japan shuts down a reactor at the largest nuclear station in the world

Today, a nuclear reactor in the largest nuclear power station in the world was shut down, after it was restarted for the first time since the Fukushima nuclear disaster in 2011, due to a technical defect that occurred hours after it resumed operation.
Yesterday evening, Reactor No. 6 at the Kashiwazaki-Kariwa Nuclear Energy Complex in north-central Japan was restarted for the first time in 14 years, as workers began lifting the control rods that work to absorb neutrons from the reactor core to begin the nuclear fission process.
But the process was halted hours later due to a technical malfunction related to the control rods, which are necessary to safely start and stop the reactors, according to Tokyo Electric Power (TEPCO).
The company, which also runs the stricken Fukushima plant, confirmed that there were no safety problems resulting from the technical defect.
The head of the Kashiwasake-Kariwa nuclear plant, Takeyuki Inagaki, announced in a press conference that he had decided to stop operating the reactor to ensure safety.
