Reuters

Japan’s Tokyo Electric Power (Tepco) will delay the restart of its Kashiwazaki-Kariwa nuclear power plant, which was originally scheduled for Tuesday, public broadcaster NHK reported on Monday, after an alarm malfunction.
It would have been the first reactor restart for Tepco since its Fukushima Daiichi nuclear power plant was hit by a powerful tsunami in 2011.
The company had planned to restart Unit No 6 at Kashiwazaki-Kariwa on Tuesday and Unit No 7 around 2030, as Japan seeks greater energy security and lower fossil fuel import costs.
NHK, ‍citing sources, said the delay was due to an alarm malfunction that occurred during equipment testing over the weekend and the new restart date should be within a few days.
Tepco said the company was examining the impact of the malfunction. It plans to hold a press conference later on Monday.
Kashiwazaki-Kariwa’s total capacity is 8.2 gigawatts. Tepco has planned to ‌resume commercial operations of reactor No 6, which has 1.36 GW capacity, on February 26.

On Saturday, an alarm, designed to go off when two or more control rods are withdrawn from the reactor fuel core, did not sound during a test at the nuclear complex.
Workers withdrew one rod and then tried to pull out another, but the alarm did not activate, according to Tepco. The company judged that the glitch could threaten the reactor’s safe operation and suspended the control rod test.
The reactor contains 872 fuel assemblies and its fission is controlled by operating 205 control rods, Tepco said.
The firm’s seven reactors at the plant in Niigata prefecture have been offline for checks since March 2012 and have been unable to restart amid public concern over the safety of nuclear power in Japan following the Fukushima disaster.
The Nos 6 and 7 reactors cleared nuclear regulators’ safety checks in 2017 but were temporarily barred from operation due to inadequate counterterrorism measures.
