Fukushima Reactor 1 Now Fully Exposed

reactor-1-on-nov-10-2016

The No. 1 reactor building at the crippled Fukushima No. 1 nuclear power plant is completely exposed after the last of 18 temporary protective covers was removed on Nov. 10.

 

Crippled Fukushima Reactor Fully Exposed for the First Time Since 2011 Disaster
The last cover was removed from the Fukushima-1 Nuclear Plant reactor No. 1, local media reported on November 10. Now all the temporary protective constructions have been demolished, and the reactor is completely exposed for the first time since 2011’s nuclear catastrophe.

Demolition works conducted by the plant’s operator Tokyo Electric Power Co (TEPCO) have been ongoing for two years. Today a large crane lifted off a 20-ton cover, the last of the 18 panels installed after the event.

The next step is the removal of 392 fuel assemblies from the spent fuel pool and melted nuclear fuel from inside the building, Japanese daily Asahi Shimbun reported

According to Japanese national broadcaster NHK, the fuel extraction will only start in four years. TEPCO is currently installing the necessary equipment and assessing the state of the reactor building’s interior in efforts to remove debris from the collapsed roof over the spent nuclear fuel pool. TEPCO has to be sure to avoid stirring the radioactive dust while shrouding the reactor building with tarpaulins.

The covers were installed in October 2011 as a temporary measure against the spread of radioactive substances after the triple meltdown of the plant.

The tragedy at the Fukushima-1 plant happened on March 11, 2011 after a devastating earthquake and tsunami struck the northeast coast of Japan, leading to the leakage of radioactive material from the plant into the surrounding environment. The nuclear accident is the largest one since the Chernobyl catastrophe in 1986. It is expected to take about 40 years to entirely clean up the area.

Last cover removed from crippled reactor in Fukushima

The No. 1 reactor at the Fukushima No. 1 nuclear power plant is completely exposed for the first time in five years after the last of the temporary protective covers for the crippled structure was removed Nov. 10.

The next step will be to extract nuclear fuel inside the reactor building, which was wrecked by a hydrogen explosion in the early stages of the March 2011 nuclear disaster.

The covers were installed the following October as a temporary measure against the spread of radioactive substances after the triple meltdown triggered by the Great East Japan Earthquake and tsunami.

A large crane lifted off the 20-ton cover, the last of the 18 panels installed, around 6 a.m. on Nov. 10.

Plant operator Tokyo Electric Power Co. began removing the covers one by one in September.

The 392 fuel assemblies are stored in the spent nuclear fuel pool inside the building. Melted fuel also remains inside the reactor.

TEPCO will assess the state of the reactor building’s interior in efforts to remove debris from the collapse of a roof over the spent nuclear fuel pool.

It will take precautions to prevent dust containing radioactive substances from being stirred up by shrouding the reactor building with tarpaulins.

Destroyed N°1 Nuclear Reactor Building Exposed at Fukushima Daiichi

 

Video shot from a Kyodo News airplane on Nov. 4, 2016, shows the destroyed No. 1 reactor building at the disaster-hit Fukushima Daiichi nuclear plant, after the removal of 16 of 18 panels covering the building. Tokyo Electric Power Co. plans to dismantle the remaining two panels the following week to complete the panel removal work that started in July 2015 as part of decommissioning the plant.

Fukushima plant building exposed as TEPCO opens old wounds

The cover on reactor 1 was installed around the building of the devastated the reactor 1 in October 2011 and Tepco plans to dismantle it by December. It remains 17 panels of 20 tonnes to move. Inside, the spent fuel pool with 392 fuel assemblies in it, which Tepco intends to empty starting 2020 …


Now this uncovered “reactor” freely spits its radioactive lungs again in the open air. Yes that’s right. Tepco had mounted this cover to avoid polluting the air. Today we go back to square one.

The three reactors 1, 2 and 3 have lost their seal and radionuclides roam freely. There is simply no way to seal leaks. Even when the pool will be emptied, the problem will still be the same.

The levels of radioactivity escaping from the three reactors are unknown until Tepco wants to give us some figures, still without any true independent body to verify.

The devastated outer layer of Fukushima No. 1 nuclear power plant’s No. 1 reactor building has been exposed for the first time in almost five years in the painstaking reactor decommissioning process.

Plant operator Tokyo Electric Power Co. began removing on Sept. 13 the exterior walls of the cover installed around the structure to prevent the dispersal of radioactive materials on Sept. 13.

Shortly past 6 a.m., a large crane began removing a massive piece of the cover installed around the reactor building. The panel dismantled that day measured 23 by 17 meters and weighed 20 tons.

The cover was installed in October 2011 as a temporary measure after a nuclear meltdown occurred following the Great East Japan Earthquake and tsunami in March that year. The meltdown caused a hydrogen explosion, blowing the walls off the building.

Once the cover is dismantled, the operator can assess the state of the building’s interiors and remove the debris fallen onto the spent fuel pool inside.

Steady progress is necessary in reconstruction, but we hope they will carry on the procedure with safety as the No. 1 priority,” said a Fukushima prefectural government official.

TEPCO said that it plans to remove the remaining 17 panels of the covering by the end of the year. The portion covering the roof has already been removed.

Once the cover is removed, the utility will begin drawing up plans to remove the 392 fuel assemblies from the spent fuel pool and melted nuclear fuel from inside the building.

The plant operator said that it plans to be extra careful during the procedure. It will shroud the building in tarpaulins once the cover is removed as a precautionary measure against dust and other materials containing radioactive materials from being carried aloft by the wind.

The utility and central government’s joint schedule for the decommissioning process of the reactor states that the removal of the fuel rods from the pool will start in fiscal 2020.

Fukushima plant building exposed as TEPCO opens old wounds

The outer layer of the crippled No. 1 reactor building at the Fukushima No. 1 nuclear power plant is exposed as Tokyo Electric Power Co. removes one of the panels covering the facility at 6:22 a.m. on Sept. 13.

TEPCO resumes removal of Fukushima plant cover

The operator of the Fukushima Daiichi nuclear power plant has resumed work to remove a temporary cover from a damaged reactor building.

Tokyo Electric Power Company had covered the partially collapsed No. 1 reactor building to prevent radioactive materials generated by the 2011 accident from spreading.

It started the removal process in July last year, the first step in the retrieval of spent nuclear fuel from a storage pool in the building.

The operation was suspended after sheets from the roof area were removed to assess the building’s condition.

On Tuesday, cranes were used to detach the panels from the side of the building, and the debris inside was exposed for the first time in 5 years. Each panel is 23 by 17 meters and weighs 20 tons.

TEPCO officials say they will spray chemicals to ensure that radioactive substances do not disperse even in strong winds.

They say they plan to complete the operation by the end of November, so that the debris can be removed. The removal of spent fuel is due to begin in 2021.

Industry ministry official Masato Kino who monitored the progress at the scene said difficult procedures will continue, but the first step has been taken. He said he hopes to carefully and safely proceed.
