Fukushima nuclear plant: Removal of fuel rods from damaged reactor begins

Fukushima nuclear plant: Removal of fuel rods from damaged reactor begins 190415141638 01 fukushima plant file super tease 960x540


Three reactors partially melted down at the plant, operated by Tokyo Electric Power Co. (TEPCO), in the wake of the earthquake and subsequent tsunami on March 11, 2011, as radioactive material leaked into the air and the Pacific Ocean.

Japan’s nuclear agency deemed the incident a Level 7 event — the highest level of nuclear crisis, matched only by the Chernobyl disaster of 1986.

As the Fukushima plant was melting down, more than 300,000 people living nearby were evacuated, according to the Red Cross.

More than 20,000 people died or went missing in the quake and tsunami, while hundreds of thousands more lost their homes.

On Monday, TEPCO announced the beginning of work to remove fuel rods from the storage pool in reactor building No. 3. The building was damaged by a hydrogen explosion during the disaster.

“Currently, there are 566 fuel rod assemblies remaining in the spent fuel pool,” TEPCO said in a press release. “As part of the decommissioning efforts, removal of the remaining fuel rods eliminates a major risk.”

Using a remotely operated machine, workers at the plant will transfer the fuel assemblies one by one from the pool into an underwater transport container. The container will be sealed, cleaned, then loaded via crane onto a truck.

The cask will be relocated into a pool on site, within a “structurally sound” building.

In November 2013, operators at the Fukushima plant started removing some 1,500 spent fuel rods from damaged reactor No. 4, which was not operational and was being used as temporary storage at the time of the accident. Last September, the Japanese government recognized the first death associated with the estimated $50 billion cleanup operation, after a man in his 50s, who worked at the plant from 1980 to 2015, died of lung cancer.
