On December 23, Japan’s Tokyo Electric Power Company restarted the nuclear fuel rod removal operation of Unit 3 of the Fukushima nuclear power plant, according to Japanese media reports. The operation was interrupted in August and was scheduled to restart in September, but has been delayed because of a persistent machine failure. On March 11, 2011, a 9.0-magnitude earthquake struck the northeastern Pacific region of Japan, which caused severe damage to the Fukushima Daiichi nuclear power plant and the Fukushima Daiichi Nuclear Power Plant following a tsunami. As a result of the earthquake, radioactive material from the Fukushima Daiichi nuclear power plant leaked outside.
It is reported that the Fukushima Daiichi nuclear power plant has 6 units, unit 1 to 3 reactor core nuclear fuel melting, and 1, 3, 4 fuel plant hydrogen explosion, unit building damage.
The removal of nuclear fuel rods from Unit 3 of the Fukushima Daiichi nuclear power plant began in April 2019, four years later than originally planned. Problems continued after the start of the operation, which was often interrupted, most recently in August, when restarts were repeatedly delayed due to machine failures.
Reported that the 23 began the operation to remove unused nuclear fuel rods, so far, the operation has removed 28 unused nuclear fuel rods. There are now 538 nuclear fuel rods in Unit 3, of which 514 are used.
